Description
Technical Field
The invention belongs to the technical field of gas transportation, and particularly relates to an analysis surge system for gas transportation pressure regulation.
Background
There are some technical problems in the current gas transportation field, which relate to the surge phenomenon and energy loss in the gas pressure regulating valve system. The method specifically comprises the following problems:
1. surging problem: surge phenomena of pressure regulating valves often occur in gas delivery pressure regulating valve systems. Surging refers to the fact that when the pressure regulating valve is affected by upstream and downstream pressure fluctuations, the diaphragm vibrates irregularly, thereby causing instability in gas flow and unstable operation of the pressure regulating valve. Surge can cause fluctuations in system pressure as well as affecting the stability and service life of the pressure regulating valve.
2. Influence of pressure fluctuations: the pressure fluctuation in the upstream and downstream directions can generate severe vibration on the diaphragm of the pressure regulating valve, thereby causing deformation of the diaphragm and further expanding the pressure fluctuation. This interaction causes a surge event to occur and reduces the performance and operating efficiency of the pressure regulating valve.
3. Energy loss problem: the pressure wave generated by the upstream and downstream pressure fluctuation is blocked when transmitted to the pressure regulating valve, so that the pressure regulating valve not only can surge the diaphragm, but also can generate severe vibration. At present, two modes of dealing with vibration of a valve body are mainly adopted, one mode is that a pressure regulating valve is fixedly connected with an upstream pipeline and a downstream pipeline, and a supporting structure is arranged on the periphery of the pressure regulating valve, so that impact of vibration on the pipeline is reduced; the other is that the pressure regulating valve is connected with the upstream and the downstream through a flexible pipe fitting, and a damping structure is arranged to absorb the vibration pressure of the pressure regulating valve. The method one is the simplest scheme, which is equivalent to hard vibration-resistant energy and has poor effect, and the method two is to solve the energy generated by vibration and also cause energy waste.
Based on the above problems, a new gas delivery pressure regulating valve system is needed to reduce the negative effects of the above problems.

In the description of the present embodiment, it should also be noted that the terms "disposed," "connected," and "connected" are to be construed broadly, unless explicitly stated or limited otherwise.
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1 to 3, the present embodiment discloses a surge analysis system for fuel gas transportation and pressure regulation, which includes a main valve body 100 and a pilot valve 200, wherein a pressure stabilizing port of the pilot valve 200 is communicated with a control chamber 110 of the main valve body 100 to control pressure regulation. The upstream of the main valve body 100 is connected to the front surge tank 300, and the downstream is connected to the rear surge tank 400. The front pressure stabilizing box 300 is internally provided with a first air bag 310, the first air bag 310 is connected with a first pressure stabilizing component 320 through a pipeline, the first pressure stabilizing component 320 comprises a first cylinder 321 and a first gravity block 322, the top of the first cylinder 321 is of an open structure, the first gravity block 322 is in sealed sliding contact with the inner side wall of the first cylinder 321, and the first air bag 310 is communicated with the bottom of the first cylinder 321; the rear-mounted surge tank 400 is internally provided with a second air bag 410, the second air bag 410 is connected with a second surge module 420 through a pipeline, the second surge module 420 comprises a second cylinder 421 and a second gravity block 422, the top of the second cylinder 421 is of an open structure, the second gravity block 422 is in sealing sliding contact with the inner side wall of the second cylinder 421, and the second air bag 410 is communicated with the bottom of the second cylinder 421. Further, the inlet of the pilot valve 200 is connected to the pre-surge tank 300 through a pipe, and the outlet is connected to the post-surge tank 400 through a pipe.
The actuation pressures of first voltage regulator assembly 320 and second voltage regulator assembly 420 may be adjusted by applying different amounts of pressure to first weight 322 and second weight 422, respectively, such as placing weights of different weights, or using weight blocks of different weights. The principle of the front surge tank 300 is the same as that of the rear surge tank 400, and when pressure fluctuation occurs upstream during operation of the gas system, the pressure fluctuation is conducted to the front surge tank 300, the front surge tank 300 generally has a larger volume, part of the pressure fluctuation is absorbed in the tank through the gas in the first gas bag 310 and the compressibility of the gas itself, more pressure fluctuation acts on the first gas bag 310, so that the first gas bag 310 contracts or expands, and the gas volume change in the first gas bag 310 is transferred to the first voltage stabilizing component 320, so that the first gravity block 322 rises or falls. The same is true of the operation of the post surge tank 400. The first gravity block 322 and the second gravity block 422 are calibrated by taking the gravity of the gravity block as calibration, so that the pressure of the gas in the first gas bag 310 and the second gas bag 410 is kept dynamically constant, and the pressures in the front pressure stabilizing box 300 and the rear pressure stabilizing box 400 are stabilized, so that the pressure fluctuation facing the upstream and downstream of the main valve body 100 is converted into the potential energy fluctuation of the gravity block, the pressure stabilizing effect is achieved, the energy generated by the pressure fluctuation is stored and released in the form of gravitational potential energy, the generation of heat energy is reduced, the energy waste is reduced, and the kinetic energy loss of gas transportation is reduced. In addition, the first airbag 310 and the second airbag 410 are respectively connected with the first voltage stabilizing component 320 and the second voltage stabilizing component 420, and once the first voltage stabilizing component 320 or the second voltage stabilizing component 420 leaks, only the gas in the first airbag 310 or the second airbag 410 leaks, and the first airbag 310 and the second airbag 410 are filled with safety gas, so that safety can be ensured. Of course, the first cylinder 321 should be provided with a limiting structure for preventing the first gravity block 322 from separating from the first cylinder 321, and the second cylinder 421 should also be provided with a limiting structure for preventing the second gravity block 422 from separating from the second cylinder 421, where the limiting structure is a conventional technical means and will not be described herein. Further, the inlet of the pilot valve 200 is connected with the front surge tank 300 through a pipe, and the outlet is connected with the rear surge tank 400 through a pipe, so that the pilot valve 200 can be adjusted earlier than the main valve body 100 receives the pressure change, and the flow change of the pilot valve 200 acts on the front surge tank 300 and the rear surge tank 400, so that the influence on the system pressure is less.
As a further scheme of this embodiment: a first elastic member 323 is connected between the first cylinder 321 and the first gravity block 322; a second elastic member 423 is connected between the second cylinder 421 and the second weight 422. The first elastic member 323 and the second elastic member 423 have smaller elasticity, so that the influence on the gas pressure in the air bag is reduced, the first gravity block 322 and the second gravity block 422 can slowly return to the vicinity of the middle position after one fluctuation, and when the system pressure and the set pressure deviate, the elasticity of the elastic members is applied to the gravity block, so that the deviation between the gravity and the system pressure can be trimmed. Meanwhile, an operator can sense the slight change of the pressure in the system by observing the deviation of the position of the gravity block, and then adjust the pressure of the gas transportation system in other modes. This embodiment is not suitable for gas delivery systems where pressure often varies.
In this embodiment, by providing a displacement sensor or a visual detector, the pressure fluctuation condition and the abnormal condition of the gas transportation system can be intuitively observed by observing the action conditions of the first gravity block 322 and the second gravity block 422, and the factors such as the pressure fluctuation direction, the size, the frequency, the duration, the period and the like which may cause the surge of the main valve body 100 are analyzed. The embodiment can reduce the use of the pressure instrument to a certain extent.
As a further scheme of this embodiment: the first gravity block 322 and the second gravity block 422 are respectively provided with a deflation channel 324, the deflation channels 324 are respectively communicated with the first voltage stabilizing component 320 and the external space and the second voltage stabilizing component 420 and the external space, and the deflation channels 324 are provided with pressure release valves 325. When the upstream or downstream pressure of the main valve body 100 is abnormally increased, and the system pressure still exceeds the normal value after the stroke of the first gravity block 322 or the second gravity block 422 reaches the limit, the pressure release valve 325 is opened under the high pressure, so that the safety gas in the first air bag 310 or the second air bag 410 is discharged for pressure release, the safety valve of the gas system is prevented from being directly started, the waste of the gas is reduced, and the safety is higher. After one pressure release, the operator should replenish the released gas in time.
As a further scheme of this embodiment: referring to fig. 4 to 6, the main valve body 100 is connected to the front and rear surge tanks 300 and 400, respectively, through flexible pipe members 700, and the flexible pipe members 700 may be conventional pipe members such as metal hoses, expansion joints, etc. The main valve body 100 is provided with a plurality of damping modules 120, the damping modules 120 comprise a third cylinder body 121, one end of the third cylinder body 121 is closed and fixedly installed on the main valve body 100, and the other end of the third cylinder body is open.

The closed space between the third cylinder 121 and the damper piston 122 is connected to the front-stage surge tank 300 and the rear-stage surge tank 400 through pipes, respectively, and the pipes are provided with check valves 500, respectively, which allow only the gas to flow into the third cylinder 121 from the front-stage surge tank 300 and to flow into the rear-stage surge tank 400 from the third cylinder 121. A third elastic member 600 is further provided between the main valve body 100 and the external fixing structure. The shock absorbing module 120 absorbs shock energy by the expansion and contraction of the shock absorbing piston 122, and when the shock absorbing piston 122 moves outwards, the shock absorbing module 120 can only suck medium from the front pressure stabilizing box 300 under the action of the check valve 500; when the damping piston 122 moves inward, the damping module 120 can only discharge the medium to the rear-mounted surge tank 400 and suck the medium one by one under the action of the check valve 500, thereby achieving the purpose of transferring the medium from the front-mounted surge tank 300 to the rear-mounted surge tank 400. The suction point in the front surge tank 300 and the discharge point in the rear surge tank 400 may be disposed in a region where the flow rate of the fluid is low, at least a region where the flow rate is less than the average flow rate, and the flow of the fluid is promoted by the action of the damper piston 122 to convert the vibration energy into the kinetic energy of the fluid, thereby utilizing the vibration energy.
The drawings of the present embodiment are applicable only as technical descriptions, and the art should consider the fluid mechanics in the actual design, and reduce the fluid kinetic energy loss by performing reasonable fluid mechanics design on the front surge tank 300 and the rear surge tank 400.
