Main piston gasket.
Using double-piston balanced type combination valve core structure, the working condition pressure of pneumatic reversing solenoid valve can be improved, it can
It works under high pressure.At high pressure, when air pressure pushes auxiliary piston to move in a straight line spool long axis, drive auxiliary piston is sealed
Pad and valve port of valve body are detached from, then main piston will be such that main piston gasket and valve port of valve body seals, realize gas circuit commutation.Piston
Design and spring can play the role of buffering, and otherwise hyperbar can bring quick washing and damage gasket and valve port of valve body,
Permanently effective work is not utilized.
It seals after valve port interface on valve body and the gasket fitting on piston, since hyperbar piston motion is non-
Often rapidly, it then impact can be brought to the gasket on spool, will affect sealing effect after long-time, increase buffer spring, it can
The use of gasket is extended to the impact damage of gasket to reduce piston valve port when the operating condition high speed of high pressure gas is closed
Service life.
Preferably, valve body uses the valve mouth structure of circular arc and inclined-plane, is formed between the inclined-plane and main piston gasket of valve port
One acute angle, valve port and main piston sealing gasket joining synapsis are circular arc.
The aperture rounding arc of valve port, in addition the purpose of design on inclined-plane is exactly to improve sealing performance.In minimum operting differential pressure
The area of sealing surface can be reduced to guarantee the leakproofness of valve, in maximum operating pressure differential with the sealing that pressure increase contacts
Face also increases, and also mitigating valve port when high speed piston is closed in this way, to the impact damage of gasket, extend gasket uses the longevity
Life.
Preferably, auxiliary piston circumferentially offers the annular groove for installing star sealing ring two, in auxiliary piston and valve body
Star sealing ring two is installed between wall；Main piston circumferentially offers the annular groove for installing star sealing ring one, main work
Star sealing ring one is installed between plug and valve interior wall.
Increase star sealing ring in piston radial, piston forms the radial double containment with axial direction, when keeping piston mobile
Maximum thrust is obtained, ensure that the reliability of the work and sealing of reversing solenoid valve.
Preferably, one end that valve deck is connect with valve body has lug boss, and when valve deck is connect with valve body, boss is in valve body
It is interior, and the circumferential direction of the lug boss offers the annular groove for installing star sealing ring two, sets between valve deck and valve interior wall
Star sealing ring two is installed.
Preferably, one end that bottom cover is connect with valve body has lug boss, and when bottom cover is connect with valve body, boss is in valve body
It is interior, and the circumferential direction of the lug boss offers the annular groove for installing star sealing ring one, sets between bottom cover and valve interior wall
Star sealing ring one is installed.
Axially projecting valve port sealing structure is increased in valve body, keeps the primary seal of reversing solenoid valve close by original radial direction
Envelope is changed to axial end face sealing, and the frictional force for solving traditional radial seal is big, be prone to wear and sealing ring is easy by high pressure
Gas is gone out the defects of groove, and star sealing ring is increased, so that foring between valve body and bottom cover, valve deck radial double with axial direction
Sealing, so that better tightness.
To adapt to naval vessel technical conditions, valve body, spool, the guide valve seat etc. of high-pressure pneumatic reversing solenoid valve of the present invention
06Cr19Ni10 stainless steel material can be used in key part.
The beneficial effects of the present invention are:
The present invention can satisfy the demand of the pneumatic commutation control solenoid valve in China's new type of ship high-pressure gas pipeline, and
And the blank of the pneumatic commutation control solenoid valve of domestic mesohigh is compensated for, meeting the needs of naval vessel uses simultaneously, it is appropriate to carry out
Extensive land market can be derived from after remodeling.
