Detailed Description
As shown in fig. 1-8, the automatic charging and dissolving device for cationic dye glacial acetic acid comprises a charging pipeline 1, a flow meter 2, a charging pump 3 and a plurality of angle seat valves, wherein the angle seat valves can adopt electric angle seat valves and pneumatic angle seat valves. The pneumatic angle seat valve is optimal, has excellent control precision and reaction efficiency, is convenient to maintain and has low failure rate. As shown in fig. 1, the angle seat valve of the present invention comprises four angle seat valves, namely, a feed angle seat valve 4, a discharge angle seat valve 5, a water inlet angle seat valve 6 and a water outlet angle seat valve 7. And the feeding pipeline 1 is sequentially provided with a feeding pump 3, a feeding angle seat valve 4, a flow meter 2 and a discharging angle seat valve 5 along the conveying direction of the material. And the feeding pipeline 1 at the upper end and the lower end of the flow meter 2 is provided with a water outlet bypass pipe 8 and a water inlet bypass pipe 9, and the water inlet angle seat valve 6 and the water outlet angle seat valve 7 are respectively positioned on the water inlet bypass pipe 9 and the water outlet bypass pipe 8. The feed pipe 1 is generally connected to a water inlet bypass pipe 9 and a water outlet bypass pipe 8 through a three-way joint 10, and two bypass pipes need two three-way joints 10.
Through the switching of feeding angle seat valve 4, ejection of compact angle seat valve 5, angle seat valve 6 and play water angle seat valve 7, can realize normal reinforced and the washing to the flowmeter, guaranteed flowmeter 2's life and detection accuracy. When feeding is needed, the feeding angle seat valve 4 and the discharging angle seat valve 5 are opened, the water inlet angle seat valve 6 and the water outlet angle seat valve 7 are closed, the feeding pump 3 pumps glacial acetic acid, and the flow meter 2 counts the feeding amount and is used as a data source for automatic control. When the flowmeter 2 needs to be washed, the water inlet angle seat valve 4 and the water outlet angle seat valve 5 are opened, the feeding angle seat valve 6 and the discharging angle seat valve 7 are closed, and the washing water washes the flowmeter 2.
The pneumatic angle seat valve can adopt the conventional angle seat valve, but when the common angle seat valve works, the valve core is controlled by the pneumatic control force output by the pneumatic mechanism. For a pipeline system with a complicated follow-up pipeline structure, a long conveying distance and a high lifting height, the conventional pneumatic angle seat valve cannot completely meet the use requirement because the limit value of the internal pressure of the pipeline is large and the pressure change is large under different feeding and conveying conditions, and the stability of the valve core is completely controlled by the pneumatic control force.
Therefore, the invention also discloses a pneumatic angle seat valve which can mechanically lock the position of the valve core at the end of the plugging stroke, and reduce the requirement on the pneumatic precision of a pneumatic mechanism.
Referring to fig. 2 and 3, the angle seat valve includes a valve body 11, a pneumatic mechanism 12, and a valve core 13, where the valve body 11 is tubular, and one end of the valve body is an inlet end, and the other end of the valve body is an outlet end, where the upper left end is the outlet end and the lower right end is the inlet end in fig. 2. Regarding the combination form of the valve body 11 and the pipeline, it may be that the two ends of the valve body 11 are provided with flanges or snap-in discs for connecting with the pipeline. One side of the valve body 11 is provided with a coupling seat 14 inclined toward the outlet end, and the coupling seat 14 is used for mounting the pneumatic mechanism 12. As shown in fig. 2, the pneumatic mechanism 12 is mounted on the connecting base 14, and the telescopic end of the pneumatic mechanism 12 faces into the connecting base 14 and is connected with the valve rod 15. The valve core 13 is arranged at the end part of the valve rod 15, and two telescopic strokes are realized under the pushing of the valve rod 15.
A valve seat 16 is arranged in the valve body 11 at a position opposite to the connecting seat 14, and a valve hole 17 matched with the valve core 13 is arranged on the valve seat 16. The pneumatic mechanism 12 drives the valve core 13 to make linear motion through the valve rod 15, so that the valve core 13 is utilized to seal or open the valve hole 17. In order to ensure the stability of the valve core 13 for plugging the valve hole 17, the valve hole 17 on the valve seat 16 is a stepped round hole, the large end of the valve hole faces the connecting seat 14, and a circle of annular sealing edge 18 with a semicircular cross section is arranged on the stepped surface of the valve hole 17. An annular sealing gasket 19 is arranged on the valve core 13 at a position opposite to the sealing rib 18, and after the valve core 13 extends into the valve hole 17, the sealing rib 18 is pressed by the sealing gasket 19 to form blocking of the valve hole 17.
In order to lock the valve element 13 in the state of blocking the valve hole 17, as shown in fig. 3, the invention is particularly characterized in that the mouth of the small end of the valve hole 17 is formed with a ring-shaped locking shoulder 20, and the locking shoulder 20 is used for cooperating with the locking head 27 and is in abutment with the locking shoulder 20 when the locking head 27 is extended.
Since the locking head 27 is in the non-blocking state (i.e., the open state of the angle seat valve), the valve element 13 needs to have a function of freely sliding up and down without interfering with the valve hole 17. However, in the blocking state (i.e., in the closed state of the angle seat valve), the locking head 27 on the valve element 13 can be extended again. Namely, it has the following functions: the valve core 13 can transversely retract, and the lifting of the valve core 13 is not influenced; but also laterally so as to form a stop with the locking shoulder 20.
In order to realize the above functions, as shown in fig. 3, the valve core 13 of the present invention includes a stepped frustum-shaped core column 21, a circular column cavity 22 is provided inside the core column 21, a main piston forming a sliding fit with the column cavity 22 is provided at an upper portion of the column cavity 22, the valve rod 15 penetrates into the column cavity 22 and is fixedly connected with the main piston, and the valve rod 15 and the top of the core column 21 form a sliding fit with gas tightness. In order to ensure stability between the valve stem 15 and the stem 13, the upper end of the stem 21 extends outwards, opposite the valve stem 15, forming a stabilizing sleeve 32. In this form, to provide a gas-tight sliding, a sealing ring may be provided directly between the stabilizer sleeve 32 and the valve stem 15, for example, a sealing groove may be provided on the inner side wall of the stabilizer sleeve 32, the sealing ring being located in the sealing groove and being held in close contact with the valve stem 15.
The bottom of the column cavity 22 of the core column 21 is also provided with a central blind hole 23, and the size of the central blind hole 23 is smaller than that of the column cavity 22, so that the main piston can drive a subsequent component to obtain a larger stroke through a plurality of smaller piston strokes in the movement process. Referring to fig. 8, a plurality of circular cross holes 24 extending along the radial direction of the stem 21 are formed in the sidewall of the stem 21 corresponding to the lower end of the central blind hole 23, a locking piston 25 is disposed in each circular cross hole 24, and a cylinder cavity 22 between the locking piston 25 and the main piston, the central blind hole 23 and the circular cross holes 24 are filled with driving oil. That is, during the up-and-down movement of the main piston, the main piston pushes down the driving oil, so that the lock piston 25 is pushed to move laterally, and the lock member (lock head 27) is extended by the lock piston 25. When the main piston rises, the lock piston 25 can be pressed back under the influence of the external pressure.
Regarding the installation manner of the locking head 27, as shown in fig. 3 and 8, a containing cavity 26 is further provided on the outer side wall of the stem 21 corresponding to the outer end of the circular cross hole 24 for communication, the containing cavity 26 is square, and a matching locking head 27 is provided in the containing cavity 26. The locking head 27 is connected to the locking piston 25 by a connecting rod 28.
In the using process:
when the valve hole 17 is blocked, as shown in fig. 4 and 5, the valve rod 15 drives the valve core 13 to move into the valve hole 17, and the sealing edge 18 presses the sealing gasket 19. As shown in fig. 6 and 7, the valve rod 15 is further pressed downward to drive the main piston to press downward in the cylinder cavity 22, the main piston pushes the locking piston 25 by using the driving oil, and then the locking head 27 is pushed out from the receiving cavity 26, and the locking head 27 is abutted by the locking shoulder 20, so as to form a limit lock for preventing the valve element 13 from retracting.
When the valve hole 17 is opened, as shown in fig. 2 and 3, the valve rod 15 drives the main piston to retreat to the upper part of the column cavity 22, and the locking head 27 retreats to the containing cavity 26 under the action of the external pressure, so that the valve core 13 is unlocked. The valve rod 15 retracts until the main piston contacts the top surface of the column cavity 22, and then the stem 21 is driven to lift up, and the valve core 13 withdraws from the valve hole 17.
Of course, when the above action is adopted, the transverse movement stroke of the locking head 27 is completely dependent on the vertical movement stroke of the main piston, which is completely dependent on the control stroke of the pneumatic mechanism; this greatly increases the requirement for precision of pneumatic control force of the pneumatic mechanism, and in order to solve the above problems, the master piston of the present invention is composed of a first plug body 29 and a second plug body 30, and a buffer spring 31 is disposed between the first plug body 29 and the second plug body 30. The first plug body 29, the second plug body 30 and the buffer spring 31 jointly form the main piston, so that the main piston is self-compressed, the self volume can be changed in a self-adaptive mode under large pneumatic control force, and the pneumatic control difficulty is greatly reduced.
In addition, because the variable main piston has a certain volume deformation capacity, the internal pressure of the pipeline is gradually increased after the charging pump 3 is continuously operated. Excessive line internal pressure will return the locking piston 25 to some extent, which will cause the second piston 30 to be pressed up due to the incompressibility of the driving oil, and to some extent, the locking head 27 may be completely pressed back into the receiving cavity 26, which may result in the locking failure of the locking head 27.
In order to solve the above problem, the present invention may further provide that, as shown in fig. 8, a high pressure locking assembly is further disposed inside the locking head 27, and the high pressure locking assembly is used to form a secondary locking to the locking head 27 when the pressure inside the pipeline is high, so as to prevent the locking head 27 from being pressed back. It comprises a high pressure locking hole 33 arranged in the locking head 27, said high pressure locking hole 33 being perpendicular to the locking shoulder 20 and being a stepped hole with a small section close to the locking shoulder 20 and a large section remote from the locking shoulder 20. Be provided with high pressure piston 34 in the high pressure locking hole 33 major segment, be provided with stop pin 35 in the subsection, stop pin 35 is connected with high pressure piston 34, stop pin 35 overcoat is equipped with reset spring 36, reset spring 36 is located between the ladder face of high pressure piston 34 and high pressure locking hole 33. The locking shoulder 20 is also provided with a pin hole 37 for cooperation with the locking pin 35.
After the valve core 13 completes the plugging of the valve hole 17, and when the pipeline pressure at the inlet end of the valve body 11 exceeds a threshold value, the pipeline pressure can overcome the elastic force of the return spring 36, and the end part of the locking pin 35 is pressed and conveyed into the pin hole 37, so that the locking pin 35 forms the anti-backing locking for the locking head 27. When the line pressure at the inlet end of the valve body 11 is lower than the threshold value, the return spring 36 can drive the locking pin 35 to be fully retracted into the high-pressure locking hole 33.
