Description
Technical field:
The present invention is relevant with equilibrium valve, and is especially relevant with the pressure regulator valve of band pilot valve.
Background technique:
The pressure regulator valve of existing band pilot valve removes to control a big membrane valve with little valve (pilot valve) and opens and closes, and realizes the pressure of large pipeline is regulated.Command valve is a little valve that is made of the nozzle shutter concepts, and following shortcoming is arranged:
1, asymmetric, the unbalanced polymorphic structure combination of overall structure, complex structure, mechanical relationship complexity, power consumption.
2, the nozzle baffle mechanism requires height to precision, sensitivity, medium cleaning degree, and operation environment is restricted.
3, it is big to establish direct-acting type diaphragm, spring, volume in the pilot valve, power consumption.
Summary of the invention:
The purpose of this invention is to provide a kind of simple in structurely, energy-conservation, highly sensitive, volume is little, makes and safeguards easily non-motile shuttle control regulation valve with low cost.
Of the present invention being achieved in that
Non-motile shuttle control regulation valve of the present invention, the upstream extremity of main valve 1 is connected with an end of threeway 4 by pipeline, first stop valve 2 is arranged on the pipeline, threeway 4 respectively with the diaphragm cavity of main valve 1, the axial bore of shuttle-type command valve 5 connects, the radial hole of shuttle-type command valve 5 is connected by the downstream of pipeline with main valve 1, second stop valve 2 is arranged on the pipeline, the valve shaft 11 of main valve 1 and valve head 12 are movingly, valve head 12 and valve seat 13, open and close and cooperate, valve head 12 is connected with barrier film 14, constitute diaphragm cavity 16 with valve gap 15, spring 17 is arranged in the diaphragm cavity 16 between valve gap and valve head upper end, the valve body 20 of shuttle-type command valve 5 is connected by bolt 24 with valve gap 22, be fixed with shuttle cover 19 in the valve body 20, the axial bore of shuttle cover 19 is communicated with the axial bore of valve body 20, and shuttle valve seat 27 is arranged on the axial bore, radial hole on the shuttle cover 19 communicates by the radial hole of valve pocket 28 with valve body 20, and peg or spindle 18 and spool 23 are connected with an end of the interior spring 27 of shuttle cover 19 respectively.
The end that spool 23 passes valve gap 22 and shuttle cover 19 is connected with spring 27.
Filter 3 is arranged on the connecting tube of the upstream extremity of main valve 1 and threeway 4.
The present invention has following advantage:
1, good integrity, the symmetrical balance formula, mechanical relationship is distinct, and is simple in structure.
2, big, the good rigidity of peg or spindle intensity can be born high temperature, high pressure, deep-etching, medium and rugged environment, high-power reliable operation.
3, mechanical relationship is distinct, amplifies the back with small pressure reduction and promotes the main valve keying.Highly sensitive, regulation range is wide, energy-conservation.
Description of drawings:
Fig. 1 is non-active shuttle control pilot valve figure of the present invention.
Fig. 2 is a non-motile shuttle control regulation valve system diagram of the present invention.
Embodiment:
The non-moving shuttle-type pilot valve of the present invention, valve body 20 is connected by bolt 24 with valve gap 22, and shuttle cover 19 is arranged in the valve body, and peg or spindle 18 slides in shuttle cover 19, and spring 27 makes peg or spindle 18 keep the trend of overlapping 19 axial end bore closures with shuttle.Spool 23 is used to adjust the thrust of spring 27.The axial bore of valve body 20 links to each other with the main valve epicoele; The radial hole of valve body 20 links to each other with the main valve downstream.
Barrier film 14 is arranged in the main valve 1`, and valve head 12 links to each other with barrier film 14, moves axially along valve shaft 11.Diaphragm cavity medi-spring 17 has to valve seat 13 directions valve head 12 and moves the trend of closing.Through hole is arranged at the diaphragm cavity top.Main valve body is all established fluid bore and is linked to each other with throttle element 4 by upstream flange with by downstream flange Pan Chu.So that link to each other with pilot valve respectively.Pilot valve and main valve are connected to a system.
Principles of Regulation:
The present invention is a kind of pressure regulator valve, and no matter much variations take place for upstream pressure and flow, and the pressure in downstream remains at a relative steady state value a little less than upstream pressure.This adjusting energy is taken from the energy of line transportation medium self.The modulating valve main valve, is realized opening or closing, thereby is realized downstream pressure relative equilibrium and stable constantly in the dynamic process of balance upstream and downstream pressure difference at the non-active shuttle control pilot valve.
Non-active shuttle control pilot valve principle:
Force value Δ P after the counteracting of shuttle chamber is after amplifying through upstream pressure after the throttling adjusting and downstream pressure in utilization, and moving up and down of control main valve realizes adjusting.
When downstream pressure raise, Δ P reduced, and spring makes peg or spindle to closing the trend operation, makes main valve close the trend operation downwards.Otherwise the trend that then obtains main valve is upwardly opened is moved.Thereby realization transient equiliblium.
