The utility model is in operation, and the electric signal detected is passed to control device, control device by explosion-proof sensor
The electric signal detected is converted into wireless signal, and passes to valve will be shown on remote control equipment, remote control equipment
On off state, operator such as needs control valve according to service condition, then sends wireless signal, nothing by remote control equipment
Line message recipient is received and sends controller after wireless signal to, and controller control actuator regulator bar is rotated, and passes through valve
The rotation of bar drives flap to carry out being turned on or off for valve.When pressure is greater than explosive-proof grade in valve, OPS can make
Corresponding evacuation prepares, and reduces casualty accident.
Telescopic joint can compensate the vibration of the pressure and pipeline that absorb valve, be broken valve inner at the last moment
Pressure shunt, so as to reach explosion-proof effect, improves safety coefficient.
The beneficial effects of the utility model are as follows：The utility model is realized by setting explosion-proof sensor and control device
To the remote control of valve, explosion accident can effectively be prevented；Corrosion-proof lining layer and pad is set to make it have
Preferable corrosion resistance and sealing property, set heat-insulating anti-explosion membrane to absorb the heat that flap is produced with valve body friction, drop
The low heat transfer to valve inner fluid, improves the explosion-proof effect of itself；The telescopic joint connected by valve body two ends, shunting
The pressure of valve inner, further increases explosion-proof effect, improves safety coefficient, and more easily can install and safeguard.
