Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sealing ball valve, concretely is a kind of sealing ball valve. BACKGROUND

[0002] Sealing ball valve is a kind of valve that rotates to open and close, and its opening and closing part is a ball. By rotating the ball 90 degrees around the axis of the valve stem, the opening and closing purposes are achieved. Sealing ball valves are widely used in industries such as petroleum, chemical, power and water conservancy, and have unique structure and high sealing performance. The valve body is usually composed of a main valve body and two auxiliary valve bodies. The ball has a journal at the upper end and an axle hole at the lower end. A series of bearings and packing boxes and other components keep the ball on the centerline of rotation, ensuring that it does not deviate during rotation.

[0003] The sealing device of the existing sealing ball valve is prone to damage. After the sealing ring is damaged, the ball valve will lose its sealing effect, resulting in the scrapping of the sealing ball valve and the need to replace a new one. Most PVC sealing ball valves are installed outdoors, and the handle switch part is prone to corrosion and breakage, leading to the scrapping of the sealing ball valve. Therefore, we need to propose a sealing ball valve. UTILITY MODEL CONTENT
