Abstract

The invention discloses a technique to decrease resistance of straight-flow type water pump controlled valve, which comprises the following steps: setting the intake valve clap as circular arc; setting cone lid as cone; forming a flow guiding body with the intake valve clap and the cone lid. This invention possesses reasonable craft and good idea, which can be spreaded widely.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to a technology for reducing resistance of a water pump control valve. Background technique [0002] Current various water pump control valves generally have the defect of large shape resistance when water is normally passed through. Contents of the invention [0003] The object of the present invention is to provide a resistance reduction technology of a once-through water pump control valve that can effectively overcome the above-mentioned defects and has a small shape resistance during normal water flow. [0004] In order to achieve the above object, the present invention adopts the following technical solution: a technology for reducing resistance of a straight-through water pump control valve, which mainly includes the following steps: the inlet disc is provided in an arc shape, the conical cover is in a conical shape, and the two forms A diverter. [0005] Due ...
