Making, dismounting maintenance procedures is complicated.
Utility model content
For the profile of air relief valve, structure complexity in prior art, it is not easy to processing and fabricating, dismounting maintenance procedures complexity
Deficiency, the purpose of this utility model is to provide a kind of three-way pressure reducing valve.
For achieving the above object, the technical solution adopted in the utility model is as follows:
Three-way pressure reducing valve, including threeway main body, relief pressure valve cartridge and spool shell；Described spool is provided with spring, piston and
String draws plug；One end diameter of described piston is more than the diameter of the other end, and its larger-diameter one end outer sheath is provided with spring, relatively
One end of minor diameter is provided with intermediate throughholes, and described string draws one end by the small diameter of described piston of plug to stretch into described centre
Fix in through hole and with described piston and be connected；Described piston can upper and lower slip in spool under string draws plug and spring effect.
Further, it is provided with drainage screen between described relief pressure valve cartridge and threeway main body.
Further, be equipped with at described piston and described spool outer casing inner wall contact position, relief pressure valve cartridge wall contacts double
Layer sealing ring.
Further, it is provided with rubber cushion between described relief pressure valve cartridge and threeway main body.
Further, described three-way valve body also can be led to fitting and is connected with nut.
Further, it is equipped with rubber cushion between described connector and three-way valve body, nut.
This utility model uses string to draw plug, spring and piston structure, draws plug to enter described piston by changing string
The degree of depth can realize the regulation of air relief valve preset pressure, regulates simple to operation, takes up room little；Described three-way pressure reducing valve is whole
Body simple in construction, dismount easy to maintenance, volume reduce, production cost can be reduced, compare traditional structure be more readily processed, intensity
Height high, pressure；And this utility model uses double-layer seal rings to strengthen the sealing of described valve body, effectively prevent situations such as leaking
Generation.
