Description

Wear-resistant flow regulating valve Technical Field The application relates to the technical field of valves, in particular to a wear-resistant flow regulating valve. Background The flow regulating valve acts on the regulation of medium and low pressure such as ore pulp, waste water and the like and uses, and this product simple structure is durable, and convenient to use is nimble, and stand wear and tear flow regulating valve is a valve that is used for controlling fluid flow specially, has good wear resistance, and stand wear and tear flow regulating valve controls the flow of medium in the body through the aperture of regulating valve. The working principle of the valve is similar to that of a common flow regulating valve, but the valve can better cope with the working condition with serious abrasion by adopting wear-resistant materials and structural design. At present, the publication date is 2023, 11 and 14, the Chinese patent application with publication number CN 220016143U provides a flow regulating valve, which comprises a valve body, a pipe body and a rotating mechanism, wherein the valve body comprises a pipe body, a valve cover, a screw, a sealing ring and a nut, the pipe body is arranged on the upper surface of the valve body, the pipe body extends to the bottom of the valve body, the pipe body comprises a flange, a water inlet pipe and a water outlet pipe, the water inlet pipe is arranged on the outer side wall of the bottom of the valve body, the water outlet pipe is arranged on the outer side wall of the valve body far away from the water inlet pipe, the water outlet pipe, the valve body and the water inlet pipe are arranged on the coaxial line, the valve body is positioned between the water outlet pipe and the water inlet pipe, and the water outlet pipe, the valve body and the water inlet pipe are mutually communicated.
