Description

Technical Field

[0001] The utility model relates to a rust-proof gas water heater valve, belonging to the technical field of water heater valves. Background Art

[0002] A gas water heater, also known as a gas water heater, refers to a gas appliance that uses gas as fuel and transfers heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water. The components include: a valve body assembly, which controls the working procedure of the entire water heater. It includes a water valve, a gas valve, a micro switch and an igniter, etc. When the water heater is installed, valves should be installed on the water inlet pipe, the water outlet pipe and the gas pipe; Patent No. CN202121134199.9 discloses a regulating valve for a gas water heater. The utility model facilitates the fixing of the gas water heater valve body by passing the gas pipelines connecting the two ends of the valve body through the tops of the two first positioning rings respectively. The elastic deformation of the spring and the fixation of the limit block enable the third positioning ring to stably drive another gas wiring pipe to be fixed to the other end of the gas water heater valve body, thereby avoiding the loosening of the connector of the gas water heater valve due to the long-term use of the gas water heater valve for opening and closing, which not only avoids gas leakage, but also avoids unnecessary economic losses.

[0003] The disadvantage of the valve disclosed above is that when the valve is installed on the gas pipeline, it does not have the effect of detecting the gas concentration. Too high a concentration of gas can easily cause the internal pressure of the pipeline to increase, which is dangerous. For this reason, we design a rust-proof gas water heater valve.
