General flow control valve is controlled using electrified, when the flow control valve of electrification control breaks down power-off suddenly, stream
Adjustable valve understands dead electricity and closes valve, and the pressure in pressure duct can be excessive at this time, may blow Valve breakage and make
Into serious security incident.
Utility model content
The purpose of this utility model is that be the defects of overcoming the prior art, and provide it is a kind of it is simple in structure, safe and reliable,
Good airproof performance, and it is capable of the bypass valve of quick pressure releasing.
To achieve the above object, the utility model uses following technical scheme：A kind of quick pressure releasing bypass valve, including perform
Mechanism, stent, valve body, valve rod, valve seat and the ball valve with valve seat cooperation able to turn on or off；The valve body is horizontally set under stent
Side, the executing agency is connected by stent with valve body, the valve rod be threaded through valve body is interior and upper end is connected with executing agency, under
End is fixedly connected with ball valve, and the valve body includes intake tunnel and exhalant canal, and the valve seat is arranged in exhalant canal, ball valve
It is arranged between intake tunnel and exhalant canal, the valve body both ends are connected with water inlet pipe and outlet pipe；Water inlet pipe is logical with water inlet
Road connects, and outlet pipe is connected with exhalant canal, and shunt valve, shunt valve one end connection are parallel between water inlet pipe and outlet pipe
The both ends that outlet pipe and shunt valve are connected to water inlet pipe, the other end are able to and the intake tunnel of valve body and exhalant canal company
It is logical.
Further, the shunt valve is equipped with manual modulation valve.
Further, the manual modulation valve is ball valve.
Further, the executing agency is pneumatic actuator.
The beneficial effect of the utility model compared with prior art is：The beneficial effect of the utility model compared with prior art
Fruit is：The utility model has been installed in parallel manual modulation valve in the bypass of flow control valve, which can control bypass
The conducting of pipe.When flow control valve breaks down or powers off, the manual modulation valve on shunt valve is opened, Jie in system pipeline
Matter flow to outlet pipe from water inlet pipe by shunt valve, and the medium or gas in pipeline can be drained from bypass, so that anti-locking system
Pressure in pipeline is excessive.The utility model is simple and compact for structure, highly practical, and suitable for the system pipeline of high pressure, operation is just
Victory, is conducive to marketing.
