Description
Technical field
The utility model is related to a kind of special gas corollary apparatus more particularly to a kind of gas piping safety valves.
Background technology
Safety valve is the widely used safety device of pressure system.When the pressure medium in pressure system is more than specified value
When, safety valve automatically turns on.When pressure medium is reduced to certain value, safety valve blowback is simultaneously automatically closed.Direct acting type is pacified
Full valve substantially divides spring and Weight type two types.What is be most widely used at present is spring loaded safety valve, working condition
When, it provides sealing force by spring, ensures equipment normal operation.When pressure rise, pressure medium overcomes spring force to make valve
Door is opened, and system pressure declines, and when pressure drops to certain value, valve returns seat under spring force.Servo high-pressure helium
Air source can be used for the primary energy of servo-drive system, to prevent pressure reducing valve downstream gas pressure from increasing extremely, in the outlet of pressure reducing valve
High pressure gas safety valve is provided on pipeline.When decompression valve outlet pressure is increased to 31MPa extremely, safety valve is opened to decompression
Valve downstream carries out pressure releasing, ensures downstream product safety.
Utility model content
The utility model provide in order to solve problem above it is a kind of it is simple in structure, installation is easy to clean, in valve body without dead
Angle, good airproof performance open and close fast, stable, service life length the gas piping safety valve of speed.
The technical solution of the utility model is：The safety valve include spherical valve body, clip, valve rod, valve seat, valve deck,
Bonnet, spring, upper spring seat, lower spring cup, locking nut and bearing, the clip are arranged in the middle part of valve body, the valve
Seat is equipped with valve seat insert, valve seals is equipped between the clip and valve body, it is close that the valve rod is equipped with valve rod
Seal, the upper spring seat and lower spring cup be arranged on valve rod up and down two parts, the spring be arranged on upper spring seat and
Between lower spring cup, the bonnet is arranged on valve body top, and locking nut is equipped between the bonnet and valve body.
The utility model is simple in structure, installation is easy to clean, in valve body without dead angle, good airproof performance, open and close that speed is fast, operation
Stabilization, service life are long.
