Description

High-tightness stop valve Technical Field The utility model relates to the technical field of stop valves, in particular to a high-tightness stop valve. Background The stop valve is also called a stop valve, is the most widely used valve, 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 and convenient to maintain, is not only suitable for medium and low pressure, but also suitable for high pressure, and the closing principle of the stop valve is that the sealing surface of the valve clack is tightly attached to the sealing surface of the valve seat by means of valve rod pressure, so that medium circulation is prevented. The utility model provides a high leakproofness welded stop valve of publication No. CN202220811918.4, including the valve body, the top of valve body is fixed with the apron, and the axle center department at apron top is fixed with the sleeve pipe, and first screw hole has been seted up to the axle center department of apron, and first screw hole and sleeve pipe intercommunication each other, has seted up inlet chamber, play water cavity and sealed chamber on the valve body, and inlet chamber and play water cavity all communicate each other with sealed chamber, the apron is used for sealed chamber's sealing, and the first screw hole and the sealed chamber intercommunication each other on the apron, first screw hole threaded connection has first double-screw bolt. According to the utility model, the first stud is driven to move downwards by screwing the slide bar, so that the first stud pushes the two sealing plugs on the fixed plate to move downwards, synchronous sealing of the water inlet cavity and the water outlet cavity is realized, the sealing performance of the stop valve is improved, the fixed plate pushes the slide block to slide along the two slide rails, the slide block is matched with the two slide rails, and the sealing performance of the stop valve is improved again.
