Description

Stop valve with leak protection prevents blockking up structure
Technical Field
The invention relates to the technical field of stop valves, in particular to a stop valve with a leakage-proof and anti-blocking structure.
Background
The stop valve is a mechanical device for controlling the flow, flow direction, pressure, temperature, etc. of fluid medium in flow, and is a basic component in a pipeline system, and the connection modes of the stop valve are divided into three types: the valve is characterized in that the valve is connected by a flange, a screw thread and a welding joint, and a stop valve, also called a stop valve, is one of the most widely used valves, is popular because the friction force between sealing surfaces in the opening and closing process is small, the stop valve is durable, the opening height is small, the stop valve is easy to manufacture, convenient to maintain, suitable for medium and low pressure and high pressure, and the closing principle of the stop valve is that the sealing surface of a valve clack is tightly attached to the sealing surface of a valve seat by the pressure of a valve lever to prevent medium circulation.
When the existing stop valve is used for sealing a water through hole, the valve clack seals the hole opening at the upper end of the water through hole by itself, the bottom of the valve clack continuously rubs against the inner edge of the hole opening at the upper end of the water through hole, the sealing performance of the valve body is reduced after long-time use, and the condition of water leakage occurs, so that the performance of the stop valve is reduced, and forced sealing cannot be performed, moreover, as the sundries in the pipeline are more, the sundries can enter the interior of the stop valve along with the water flow to cause the interior of the stop valve to be blocked, the pressure in the stop valve can be increased, and the potential safety hazard exists, meanwhile, when the internal pressures of the water inlet pipe and the water outlet pipe are unequal, the pressure of inlet water is lower than that of outlet water, backflow can occur in the pipeline, most of the existing stop valves are of an integral casting structure, it is extremely inconvenient to oil maintenance and maintenance to its inside, for this reason we have proposed a stop valve with leak protection anti-clogging structure.
