Description
Technical field
This utility model relates to a kind of collection transfer device, controls device particularly to gas gathering and transportation.
Background technology
The defeated process of petroleum gas collection is generally transported by gathering and transporting device, one is that security performance is high, two is save production cost, potential safety hazard is there is in natural gas in the process producing transhipment, realizing automatic closing and alarm generally by installing relief valve, pressure release etc., along with production-scale expansion, relief valve can not realize safety in production, causes that potential safety hazard strengthens.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, it is provided that gas gathering and transportation controls device.
nullIts technical scheme is: include main valve、Pilot valve、First connecting pipe、Second connecting pipe、Filter、Anti-explosion pressure gage、Explosion-proof controller，The top inlet of described main valve connects pilot valve by the second connecting pipe，The bottom inlet of described main valve connects pilot valve by the first connecting pipe，The first described connecting pipe is provided with filter and anti-explosion pressure gage，Described explosion-proof pressure list catenation explosion-proof controller，It is provided with air cavity inside described main valve，Valve pocket it is provided with inside air cavity，Valve core of main valve it is provided with inside valve pocket，The bottom of valve core of main valve is supported by main valve，The top of described valve core of main valve connects main spool spring，Main spool spring compression valve core of main valve realizes the Guan Bi of main valve，Described pilot valve includes supporting spring、Regulate screw、Valve rod、Piston，The bottom of valve seat is provided with piston，The top of piston connects valve rod，The top of valve rod connects adjustment screw by supporting spring，Described valve seat is provided with oil leak hole.
Described piston is provided with damping hole.
The beneficial effects of the utility model are: simple in construction, it is achieved that safety in production transport, applied range, can produce accurate, stable differential pressure signal, and intensity is high, non-leakage, blockage resisting, adapts to the pipeline of various sizes, is applied to the occasion of High Temperature High Pressure.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model；
In upper figure: main valve 1, pilot valve the 2, first connecting pipe the 3, second connecting pipe 4, filter 5, anti-explosion pressure gage 6, explosion-proof controller 7；Air cavity 1.1, valve pocket 1.2, valve core of main valve 1.3, main spool spring 1.4, main valve 1.5；Support spring 2.1, regulate screw 2.2, valve rod 2.3, piston 2.4.
Detailed description of the invention
In conjunction with accompanying drawing 1, the utility model will be further described:
nullThis utility model includes main valve 1、Pilot valve 2、First connecting pipe 3、Second connecting pipe 4、Filter 5、Anti-explosion pressure gage 6、Explosion-proof controller 7，The top inlet of described main valve 1 connects pilot valve 2 by the second connecting pipe，The bottom inlet of described main valve 1 connects pilot valve 2 by the first connecting pipe 3，The first described connecting pipe 3 is provided with filter 5 and anti-explosion pressure gage 6，Described explosion-proof pressure list catenation explosion-proof controller 7，Described main valve 1 is internal is provided with air cavity 1.1，Air cavity 1.1 is internal is provided with valve pocket 1.2，Valve pocket 1.2 is internal is provided with valve core of main valve 1.3，The bottom of valve core of main valve 1.3 is supported by main valve 1.5，The top of described valve core of main valve 1.3 connects main spool spring 1.4，Main spool spring 1.4 compresses valve core of main valve 1.3 and realizes the Guan Bi of main valve 1，Described pilot valve 2 includes supporting spring 2.1、Regulate screw 2.2、Valve rod 2.3、Piston 2.4，The bottom of valve seat 2.5 is provided with piston 2.4，The top of piston 2.4 connects valve rod 2.3，The top of valve rod 2.3 connects adjustment screw 2.2 by supporting spring 2.1，Described valve seat 2.5 is provided with oil leak hole 2.6.
Described piston 2.4 is provided with damping hole.
When the upstream pressure of safety protective valve is lower than set-pressure; support spring on pilot valve pushes spool to valve base sealing; gas medium enters valve core of main valve epicoele by the second connecting pipe through pilot valve, and valve core of main valve is close to valve seat under spring force, and arranged at safety valve is in zero leakage condition.
When the upstream pressure of safety protective valve is more than set-pressure; medium overcomes the pressure supporting spring, and pilot valve spool moves, and over-pressure gas piston enters piston cavity of resorption; lifting surface area increases; promoting and move on piston, piston is slow by shifting speed due to the work of damping hole, and pilot valve is easily opened; on main valve, the gas of intracavity is discharged from pilot valve outlet; epicoele pressure release, main valve is opened, and medium discharges rapidly.
The above, be only preferred embodiment of the present utility model, and this utility model is all revised possibly also with the technical scheme of above-mentioned elaboration or is revised as equivalent technical scheme by any those of ordinary skill in the art.Therefore, any simple modification carried out according to the technical solution of the utility model or substitute equivalents, belong to the greatest extent the scope that this utility model claims.
