The unified installation of pipeline gas facilitates the realization of fully enclosed management. Although the safety of pipeline gas is much higher than that of bottled liquefied gas cylinders, gas leakage accidents still occur from time to time. great safety hazard
[0004] In order to detect gas leakage, some users will install a gas alarm to detect whether the gas has leaked through the gas leakage detection sensor in the gas alarm, and then send out an alarm sound to remind the user that the gas has leaked; the current gas alarm can only Detection, prompting the user through an alarm, cannot directly cut off the gas path after the gas leaks, so it is necessary to develop a solenoid valve that can be linked with the gas alarm to automatically cut off the gas path when the gas leaks

The invention relates to a gas electromagnetic valve powered by a low-voltage battery. A valve body of the gas electromagnetic valve is provided with an air inlet and an air outlet. A valve port is arranged between the air inlet and the air outlet. A base is fixed to the valve body and internally provided with a main control board. The main control board is provided with a wireless receiving and transmitting module which is in signal connection with a gas alarm device. An electromagnet assembly is further arranged in the base and comprises a magnet iron core, a movable iron core and a coil. Anelectric loop is formed by the coil and the low-voltage battery in the base. The part, on the periphery of the movable iron core, below the coil is provided with a permanent magnet. A seal ring is fixed between the valve body and the base. A seal pad is fixed to the lower end of the movable iron core, penetrates through the seal ring and is matched with the valve port. A spring is arranged between the seal pad and the seal ring, a reset pull rod is fixed to the upper end of the movable iron core, and the upper end of the reset pull rod penetrates through the magnet iron core and stretches outof the base. The gas electromagnetic valve has the advantages that the structure is simple and reasonable, safety and reliability are achieved, linkage with the gas alarm device is adopted, and a gaspath is automatically cut off when gas leaks.
Description
technical field [0001] The invention relates to the technical field of gas alarm linkage devices, in particular to a gas solenoid valve powered by a low-voltage battery. Background technique [0002] The main component of gas is methane. When the concentration in the air reaches 10%, it can suffocate people to death. When the content reaches 5%-15%, it will deflagrate when encountering a fire source. Therefore, the damage caused by gas leakage is extremely great. [0003] With the development of social economy, people have higher requirements for their quality of life and living environment after meeting the basic needs of life. The unified installation of pipeline gas facilitates the realization of fully enclosed management. Although the safety of pipeline gas is much higher than that of bottled liquefied gas cylinders, gas leakage accidents still occur from time to time. a great safety hazard. [0004] In order to detect gas leakage, some users will install a gas alarm t...
