Convenient-to-mount rotatable valve with anti-corrosion structure

Abstract

The invention relates to a convenient-to-mount rotatable valve with an anti-corrosion structure. The rotatable valve comprises a valve deck, a clamping plate and a traction rod, wherein a fixing discis arranged at the top end of the valve deck, and a top cover is distributed in the middle part of the top end of the fixing disc; and the clamping plate is welded to the two sides of the top end of the middle part of the top cover, a waist tightening hole is formed in the middle part of the clamping plate, and a fixing screw penetrate through the interior of the waist tightening hole. According to the convenient-to-mount rotatable valve with the anti-corrosion structure, through the arrangement of the clamping plate and the waist tightening hole, the waist tightening hole transversely penetrates through the middle part of the clamping plate, the whole clamping plate can effectively limit and fix the traction rod, meanwhile, the fixing screw penetrates through the middle part of the traction rod, and the traction rod is longitudinally fixed through the fixing screw, so that it is guaranteed that the sliding range of the whole traction rod is within the length range of the waist tightening hole, and it can be effectively guaranteed that the whole traction rod is distributed in a horizontal plane; and meanwhile, the whole clamping plate is connected with the top cover in a welding mode, so that the connecting strength of the clamping plate is high, and the clamping plate is not prone to break in the using process.

Description

technical field [0001] The invention relates to the field of rotary valves, in particular to a rotatable valve with an anti-corrosion structure for easy installation. Background technique [0002] Rotary valve, also known as star valve, is a regulating valve that changes the valve from open to closed by rotating a rotating part such as a rotating baffle 90 degrees. Flow is allowed or cut off by a rotating part. A rotary valve whose rotating parts can be rotated 90 degrees is called a 1 / 4 rotary valve. Sometimes the classification of 1 / 4 rotary valves can be extended to rotary valves with a rotation angle of less than 270 degrees. There are valves and pipe fittings, which are used in the connection or control system of pipelines. Valves and pipe fittings cannot exist independently and complement each other. Valve fittings are available in carbon steel and stainless steel, as well as PVC, or other materials. [0003] The existing rotary valves do not have a good preventive ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a rotatable valve with an anti-corrosion structure that is easy to install, so as to solve the problem that the existing oral irrigator proposed in the above background technology has a large volume and cannot be used by different groups of people, and the water pressure during flushing It is easy to cause damage to the oral cavity if it is too large, and the poor flushing stability will easily cause large shaking problems
