Gas safety valve with anti-leakage alarm function

Abstract

The invention relates to the technical field of gas safety equipment, and discloses a gas safety valve with an anti-leakage alarm function. The gas safety valve with the anti-leakage alarm function comprises a safety valve body, the middle of an inner cavity of the safety valve body is movably sleeved with a valve element, and a sealing ring is arranged in a gap between the safety valve body and the valve element; and two sets of pressure rubber rings are arranged on the portions, located on the two sides of the valve element, of the inner cavity of the safety valve body correspondingly, capillary tubes are arranged in the two sets of pressure rubber rings correspondingly, and a balance sleeve pipe is fixedly installed at the bottom end of a buzzer. According to the gas safety valve with the anti-leakage alarm function, a main contact guide rod, a triggering connecting rod and structures on the triggering connecting rod are arranged, a set of triggering mechanisms can be effectively arranged in the safety valve, only when the triggering mechanisms are opened and gas is connected, the buzzer and a heating spray pipe can be triggered to be started, so that the safety of the gas valvein the using process is guaranteed, the phenomenon of false triggering cannot occur when the gas safety valve is closed, and the reliability and the stability are high.

Description

technical field [0001] The invention relates to the technical field of gas safety equipment, in particular to a gas safety valve with an anti-leakage alarm function. Background technique [0002] As the most common cooking and heating equipment in family life, gas appliances mainly generate heat by burning flammable gases. However, because these gases are flammable and explosive, they must be used in daily use. Install a safety valve on the pipeline to reasonably control the opening and closing of the gas pipeline, and can cut off the gas in time when it leaks, thereby effectively preventing the occurrence of major safety accidents. [0003] However, the gas safety valve itself is a potential safety hazard. Because it needs to be opened and closed frequently during its use, it is inevitable that there will be gaps between the valve body and the valve core and between the valve core and the sealing ring. The phenomenon of wear and tear, and this kind of wear is also undetect...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a gas safety valve with an anti-leakage alarm function, which has the advantages of being able to automatically block the safety valve itself, has high safety and reliability, and has high sealing performance after leakage is blocked. The gas safety valve itself is a safety hazard. Because it needs to be opened and closed frequently during its use, it will inevitably cause wear and tear between the valve body and the valve core and between the valve core and the sealing ring. The phenomenon, and this kind of wear and tear is also undetectable by people during inspection, so that after people smell the pungent smell of gas leakage, when they habitually close the gas safety valve, they cannot know that the safety valve itself is damaged. There is a phenomenon of leakage, and then the problem of cutting off the main gas valve is ignored
