Description
Technical field
The utility model is related to a kind of thermovalve, and a kind of temperature-sensitive for more particularly to being used in pneumatic system pipeline discharges
Valve.
Background technology
When being not suitable for being opened or closed using electric-control system the equipment such as corresponding door, come usually using atmospheric control
The switch of door is controlled, there is temperature detecting function, in the prior art temperature in use sensor detection temperature in atmospheric control
Signal, the temperature signal that will be detected feeds back to executing agency, and after ambient temperature exceedes certain value, executing agency is moved
Make, open or close door, in pneumatic system use electronic component, when occurring situations such as fire, although in general with
Compressed air is carried out opening or closing for driving gate and is closed, but electronic component is often subject to influence and leads to not use, and corresponding door cannot
Normally open or close.
Utility model content
For defect of the prior art, the purpose of this utility model is to overcome above-mentioned deficiency of the prior art
A kind of place, there is provided temperature-sensitive relief valve, solves to use electronic component dangerous and insecure problem, this hair in pneumatic control system pipeline
Bright simple structure, it is safe and reliable.
What the purpose of this utility model was realized in:A kind of temperature-sensitive relief valve, including valve body, valve element, spring, temperature-sensitive
Glass tube and fixed seat, are provided with air inlet and gas outlet on the valve body, be connected through valve pocket between air inlet and gas outlet, described
Fixed seat is threaded in valve body one end, and temperature-sensitive glass tube is supported between fixed seat and valve element, and the valve element is equipped with
In valve pocket and air inlet and gas outlet are isolated, the spring is supported between valve element and the inner bottom part of valve pocket, described
Temperature-sensitive glass tube interior sealing has expanded by heating medium, and the gas outlet is arranged on valve body, when temperature-sensitive glass tube receives thermal fracture,
The air inlet and gas outlet communicate.
When ambient temperature is normal, compressed air is constantly passed through air inlet, air pressure and valve seat and the spring bullet of valve core chamber
Power is equal, and temperature-sensitive glass tube is withstood between valve element and fixed seat, and air inlet is obstructed with gas outlet；It is past according to real work needs
Different expanded by heating media are enclosed in different temperature-sensitive glass tubes, so as to be set in different temperature expansion points, when environment temperature
When degree reaches setting value, glass tracheal rupture makes air inlet be communicated with gas outlet, and the airline pressure being connected with air inlet declines,
So as to export a decompression signal, make coupled pneumatic system output action, open or close corresponding door or other set
It is standby；The utility model is operationally safe and reliable, simple structure, can be applied to fireproof partition door etc. in pneumatic system pipeline.
In order to improve the sealing between valve element and valve body, seal is provided between the valve element and valve pocket inwall.
For the ease of the installation of valve element, the valve element is provided with location hole, temperature-sensitive glass tube phase towards temperature-sensitive glass tube side
The projection for being provided with insertion location hole should be held.
Used as further improvement of the utility model, the air inlet is axially arranged along valve body and is located remotely from fixed seat
The valve body other end.
Used as further improvement of the utility model, the expanded by heating medium is can not burning liquid.
Used as further improvement of the utility model, the expanded by heating medium is non-combustible gas.
