Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of regulating valves, in particular to a regulating valve with a small-diameter valve port. Background Art
[0002] A small-diameter regulating valve is a device used to control the flow rate and pressure of fluids, suitable for fluid regulation in small-diameter pipeline systems. It usually consists of components such as a valve body, a valve disc, a valve stem, a valve seat, and an actuator. The valve disc of a small-diameter regulating valve is usually a disc or a sphere, and the flow rate and pressure of the fluid are adjusted by rotating or moving up and down. The gap between the valve body and the valve disc can be controlled by adjusting the position of the valve stem, thereby achieving the regulation of flow rate and pressure.
[0003] The actuator of a small-diameter regulating valve can be manually operated or automatically controlled. For existing regulating valves applied to water flow management, since the diameter of the connection between the valve and the water pipe is in a fixed state, it is impossible to clean the inside. After long-term use, some residues will accumulate inside, resulting in corrosion of the valve body interior and thus reducing the service life of the valve body. Moreover, some existing valve body interiors cannot filter the passing fluid, which will reduce the use effect of the valve body. Therefore, it is urgent to solve the above problems.
