Hebei Qingxian men developed gas terminal timer valve

People often forget to close the valves behind the watch after using gas, and there are a lot of accidents. In order to prevent more incidents from happening, Zhao Hongdong, a man from Qing County, Hebei, has developed a gas terminal timer valve. After the appointment time is reached, the timer valve will automatically cut off the pipeline gas to protect the user's gas safety. This invention fills the gap of the gas pipeline terminal without a reliable timing valve, and Zhao Hongdong recently took back the national invention patent certificate issued by the State Intellectual Property Office and the test report of the certification of the National Gas Appliance Quality Supervision and Inspection Center.

After graduating from high school, Zhao Hongdong has been studying electronics, machinery, and other specialties and has started an electrical equipment company. Zhao Hongdong said that the valve behind the watch is located under the gas meter and is connected to the stove by a rubber hose. Usually, the valve can only be opened or closed by a person. This also made many people careless, forget to close the gas valve, leaving a security risk. In order to avoid the risk of these gas users, he began to work on the valve behind the watch. Zhao Hongdong said that the timer valve he developed is different from the ordinary valve. It is in the safety insurance every time it is used. It is automatically turned on after the required time. Usually, it takes 20 minutes each time, up to one hour, not waiting for the accident. , it is the closing time. In addition, timing valves are more airtight than ordinary valves and their service life is extended to 8 years.
