A Timed Domestic Gas Safety Valve

Abstract

The invention relates to the technical field of pipeline equipment, and discloses a timing household gas safety valve, which includes a self-closing valve body, a moving magnet is movably connected to the self-closing valve body, and a closing plug is movably connected to the moving magnet. A fixed magnet is installed below the moving magnet. When the user forgets to close the valve during the use of gas, since the gas flow has not changed for a long time, the air pressure in the compression tank and piston cylinder will gradually increase, which will move the moving magnet, trigger the valve to close, and cut off the gas, which can avoid Overcooking can also prevent the overflowing water from dousing the gas, causing gas leakage and improving gas safety. Secondly, when the gas end leaks, a relatively stable airflow will be formed in the gas pipeline, triggering the valve to close. When there is an unperceivable and easy leakage at the end, it will frequently trigger the gas shutdown, which can not only improve the prevention of gas leakage, but also play the role of gas leakage detection.

Description

technical field [0001] The invention relates to the technical field of pipeline equipment, in particular to a timing household gas safety valve. Background technique [0002] see Figure 6 , is a common gas safety valve on the market, including a valve body, a setting magnet, a sealing plug and a driving block. When the pressure in the valve body drops, the volume of the expansion bag shrinks, and the magnetic force between the driving block and the setting magnet becomes larger, and the setting magnet Attract the drive block to move, drive the plug to move, and close the gas valve. [0003] Although this type of gas valve is automatically closed when the pressure of the valve body drops after the gas leaks to improve the safety of gas use, if the user forgets to close the gas during normal use, it is easy to extinguish the fire and cause an accident. A gas leak may cause a safety accident. [0004] Secondly, the existing safety valves often need to cooperate with electron...

Problems solved by technology

[0003] Although this type of gas valve is automatically closed when the pressure of the valve body drops after the gas leaks to improve the safety of gas use, if the user forgets to close the gas during normal use, it is easy to extinguish the fire and cause an accident. Gas leakage, causing safety accidents

[0004] Secondly, the existing safety valves often need to cooperate with electronic gas leakage detection equipment when detecting gas leakage. After detecting that the gas concentration in the air is too high, the control valve is closed. Automatically closed when streaming, there is a big security risk
