Description

Technical Field

[0001] The utility model relates to the technical field of stop valves, in particular to a stop valve with a leakage alarm function. Background Art

[0002] The stop valve is a pipeline control device that is mainly used to cut off or connect the flow of fluid. The stop valve is widely used in industrial control systems to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. There are many kinds of stop valves currently available on the market, but there are still some disadvantages;

[0003] For example, in actual use, when the fluid flows inside a general stop valve, if there is a fluid leakage and no alarm occurs, the fluid will leak more and more, and it cannot be repaired in time, which will lead to the safety risk of scalding of personnel and even threaten life safety. At the same time, there is no filtration system inside the general stop valve. If the fluid contains large particles and circulates inside the stop valve for a long time, it will cause the stop valve to be blocked. In addition, the valve stem of the general stop valve is threaded, and it is exposed to dust for a long time. Therefore, we propose a stop valve with a leakage alarm function to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a stop valve with a leakage alarm function to solve the problem of the current stop valve proposed in the above background technology that when the fluid flows inside the stop valve, if the fluid leaks, no alarm can be given, the fluid will leak more and more, and it cannot be repaired in time, which will lead to the safety risk of scalding of personnel and even threaten life safety. At the same time, if there is no filtering system inside the general stop valve, if the fluid contains impurities and particles and circulates inside the stop valve for a long time, it will cause the stop valve to be blocked. In addition, the valve stem of the general stop valve is threaded, which is exposed to dust for a long time. Problems such as erosion.
