Abstract
The present invention is a kind of control valve without external driven by energy, belongs to valve technology field.The invention discloses operation principle and the structure composition of this product.Including valve body, spool, valve seat, Pneumatic-hydraulic actuator, reversal valve, handwheel, power transmission shaft, support shaft and pipe-line system.Its technical characteristic is to connect executor and valve body and piston type valve seat by pipe-line system, makes the operation of valve just can control the break-make of valve without the external energy, tube track media self-energy.Provide the benefit that the severe occasion of valve installation environment, without being manually entered operation, solves and avoids in industrial pipeline and Municipal pipeline because valve operation occurs that the accident of person life security occurs.
Description
Technical field
The present invention relates to valve technology field, particularly relate to the piston type valve seat self sealing valve that a kind of self-powered controls.
Background technology
At present, apply at city thermal pipeline and Oil and Natural Gas Transportation Pipeline, general all do not match the external energy (as electric energy, gas can etc.), this allow at present on the type pipeline valve of application to operate as requisite switching device and necessarily send workman to go into the well manual operation.And often occur during workman's down-hole operation some contingencies (such as because of steam make that ambient temperature is too high, carbon monoxide poisoning, gas concentration lwevel too high suffocate, combustible gas deflagrating etc.), easily cause personal injury event.It addition, the work phase of city thermal pipeline conveying only some months in winter, in the time period not used for a long time, valve sealing face gets rusty easily to such an extent as to is difficult to drive time next time enables.
Summary of the invention
The technical problem to be solved is for the above-mentioned state of the art, and provides a kind of without the external energy, uses the energy of pipeline fluid itself as driving, it is possible to the passive intelligent being not required to artificial down-hole operation controls valve.
(0004) present invention solves the method that above-mentioned technical problem used and is:
(0005) the piston type valve seat self sealing valve that a kind of self-powered controls is made up of valve body, spool, valve rod, valve seat, Pneumatic-hydraulic actuator, handwheel, pipe-line system, reversal valve and connector.It is characterized in that: valve body uses full welding valve body or combination type valve body, spool uses spherical or cock shape structure, and seat design becomes separable piston type self sealss form.
(0006) driver of valve uses pneumatically or hydraulically executor (being determined, the most consistent) by pipeline pumped (conveying) medium, and the pumped (conveying) medium that the power of executor is connected to main pipeline by pipe-line system provides.
(0007) piston type self sealss valve seat can carry out being freely separating and closing and reduces valve operation moment of torsion and play oneself's sealing function.
(0008) switch drive of executor and the separation of valve seat and Guan Bi are controlled by two four-way change-over valves respectively.
(0009) pipeline system design becomes metal hose, can be conveniently integrated into pithead position control or remotely control.
(0010) handwheel band clutch design, during Pneumatic-hydraulic actuator action, handwheel disengaging does not works;When operating without Pneumatic-hydraulic actuator, Isolating Switch closes, and handwheel can operate valve switch.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with the accompanying drawings the present invention is described in further detail.
Fig. 1 to Fig. 2 show the principles and structure schematic diagram of the present invention.The piston type valve seat self sealing valve that a kind of self-powered controls, its composition includes:
01 valve body
02 spool
03 protection valve
04 valve seat
05 reversal valve A
06 reversal valve B
07 Pneumatic-hydraulic actuator
08 handwheel driver
09 pipe-line system
10 power transmission shafts
11 support shafts
12 pistons
13 piston rings
14 valve base sealing rings
15 location briquettings
16 sealing gaskets
As shown in Figure 1; 03 protection valve generally lies in opening (just cutting out during valve maintenance); pipeline medium carries out power transmission through 09 pipe-line system; flow to 04 valve seat medial surface (by valve center line one side) by 05 four-way change-over valve A, promote 04 valve seat to do piston like motion and separate spool (valve torque is greatly reduced).Pipeline fluid enters 07 Pneumatic-hydraulic actuator A mouth by 06 four-way change-over valve B simultaneously, promotes 10 power transmission shafts to make 02 spool do 90 degree of actions that turn clockwise, thus realizes valve opening.
As in figure 2 it is shown, first open switching 06 four-way change-over valve B, make pipeline fluid enter 07 Pneumatic-hydraulic actuator A mouth, promote 10 power transmission shafts to make 02 spool do 90 degree of spinning movements counterclockwise, thus realize spool return.Again switch 05 four-way change-over valve A, make pipeline fluid enter 04 valve seat lateral surface (by valve two ends one side), promote 04 valve seat to do piston like motion and fit tightly spool, make up to sealing effectiveness, thus realize valve and completely close.
09 pipe-line system uses metal hose structure, is all integrated in a control box, is installed to pithead position, facilitates the operation of 05 reversal valve A and 06 reversal valve B without having gone into the well.
In valve maintenance or in emergency circumstances, the on-off control of valve has been driven by handwheel.First closing 03 protection valve, open the Isolating Switch in 08 handwheel driver, make power transmission shaft depart from 07 Pneumatic-hydraulic actuator, the switch motion that operated by handwheel at this moment can be used to carry out valve carries out repair and maintenance to facilitate.
The preferred version of the ultimate principle of the present invention, technical characteristic and the present invention has more than been shown and described.For those skilled in the art, some improvements and modifications without departing from the principles of the present invention, should be regarded as protection scope of the present invention.Claimed scope is defined by appending claims and equivalent thereof.
