Abstract

The invention provides a valve good in sealing performance. The valve comprises a valve body. According to the valve good in sealing performance, first threads are formed at the two ends of the valvebody; the center end of the top of the valve body is fixedly connected with a rotating seat; the bottom of the rotating seat is fixedly connected with multiple reinforcing ribs; the bottoms of the reinforcing ribs are fixedly connected with the top of the valve body; each reinforcing rib is of a polyhedron structure, wherein the side face of the polyhedron structure is triangular, and the front face of the polyhedron structure is rectangular; the rotating seat is of a hollow cylinder structure; a rubber ring is fixedly connected in the rotating seat and is of a hollow cylinder structure; a valve rod is rotationally connected in the rubber ring; a second thread is formed at the top of the valve rod, and the periphery of the second thread is connected with a handle in a sleeved manner; a rubber sleeve is bonded and fixed to the surface of the handle; antiskid grain is arranged on the surface of the rubber sleeve; and a fixed nut is spirally connected to the top of the second thread. Through the additionally-mounted rubber ring, sealing performance of the valve can be increased, and liquid leakage can be avoided.

Description

technical field [0001] The invention relates to the technical field of water valve production, in particular to a valve with good sealing performance. Background technique [0002] A valve is a commonly used mechanical component with a wide range of applications. Commonly used valves have a variety of structures. For example: the valve includes the valve body, valve core, valve stem and wheel disc. The valve core is located in the valve body, the bottom end of the valve stem is fixedly connected with the valve core, and the top end of the valve stem is fixedly connected with the wheel disc. There is an inlet and an outlet on the valve body. By rotating the wheel, the valve stem drives the valve core to rotate. The rotation of the valve core realizes the opening and closing of the valve, thereby realizing the flow of fluid through the valve or preventing its flow through the valve. In the existing valve structure, due to the limitation of the manufacturing process, the p...
