Problems solved by technology

[0002] At present, the common gas pressure reducing valves on the market do not have a gas leakage alarm device, let alone a gas leakage control device. Ordinary families and restaurants use gas and natural gas to leak, which can easily cause fires and explosions, threatening the lives and property of the people. Therefore, in order to protect the lives and properties of the people, people need a device with simple installation, gas leakage alarm, and gas leakage control gas valve closure.

example 1

[0025]Example 1: Common household kitchens use gas tanks to boil water, and the gas tanks are equipped with the gas leak protector pressure reducing valve of the present invention. Gas stove, water is being boiled on the gas stove, the owner goes out, the water boils, and the flame is extinguished, the unburned gas is continuously discharged into the room, and the indoor gas concentration continues to rise, reaching the threshold value of the gas signal detection design, and the gas signal The detection circuit is self-locking and starts the solenoid valve control circuit, closes the solenoid valve, cuts off the gas supply, starts the sound and light alarm circuit to drive the buzzer to emit a harsh alarm sound, and drives the gas leakage alarm luminous tube to flash. As the gas no longer leaks, the indoor gas concentration continues to decrease, but the gas signal detection circuit has been self-locked, so the solenoid valve is still in the off state, and the sound and light a...

Abstract

The invention discloses a pressure reducing valve of a gas leakage protector, which is simple to install, gives an alarm when gas leakage occurs and controls closing of a gas valve when gas leakage occurs, replaces a common gas pressure reducing valve on the market, provides a protective barrier for people to use liquefied gas and natural gas, and enables people to use liquefied gas and natural gas more safely. The pressure reducing valve of the gas leakage protector comprises a leakage-proof rubber ring, a locking screw, an electromagnetic valve, a pressure reducing valve body and a gas anti-skid outlet, a shell is arranged on the lower portion of the pressure reducing valve body, and a gas detection alarm control circuit, a battery and a buzzer are installed in the shell. The gas detection alarm control circuit comprises a gas concentration alarm control circuit, a gas flow alarm control circuit and a battery power shortage alarm circuit.

Description

technical field [0001] The invention relates to the field of combustible gas alarms, in particular to a pressure reducing valve for a gas leakage protector. Background technique [0002] At present, the common gas pressure reducing valves on the market do not have a gas leakage alarm device, let alone a gas leakage control device. Ordinary families and restaurants use gas and natural gas to leak, which can easily cause fires and explosions, threatening the lives and property of the people. Therefore, in order to guarantee the life and property safety of the people, people need a device that is simple to install, gas leakage alarm, and gas leakage control gas valve closing. Contents of the invention [0003] The purpose of the present invention is to provide a device with simple installation, gas leakage alarm, and gas leakage control gas valve closure, to replace the common gas pressure reducing valve on the market, and to add a protective barrier for people to use liquefi...
