Valve plate and one-way valve

Abstract

The present invention discloses a valve plate comprising valve clacks and mounting pillars connected to the valve clacks, wherein a plurality of valve clacks are distributed radially; a partition groove is formed between two adjacent valve clacks; the mounting pillars are arranged at the junction of each valve clack; an annular convex rib is arranged on the lower surface of each valve clack; the annular convex ribs are arranged between the partition grooves and the mounting pillars and are collinear with axes of the mounting pillars. By virtue of the annular convex rib structure, the useless contact area between the valve clacks and valve seat water pressing grooves can be reduced; the returning elastic force used for sealing a connection hole is correspondingly increased; the valve clacks are accurately clung to the periphery of the connection hole, thereby achieving the better effect of sealing the connection hole. During long-term operation, the material of the valve plate is aged, fatigued and shrunk, so the elasticity is reduced; the elastic returning force is capable of ensuring the sealing effect all the time, thereby preventing the water in a low-pressure area from reversely flowing or leaking the water to a high-pressure area. The invention also discloses a one-way valve comprising the valve plate.

Description

technical field [0001] The invention relates to the technical field of pressure stabilizing pumps, and more specifically, to a valve plate and a check valve for a stabilizing pump. Background technique [0002] The existing one-way valve of the voltage stabilizing pump is the most typical of the Chinese patent with the application number 200520052218.8 published by Foshan Delta Electric Technology Co., Ltd. This patent discloses a piston valve (also known as a one-way valve). [0003] The disc of the one-way valve is in the shape of a flower, radially divided into three valve discs, each pressure water area is slightly concave downward, the bottom surface of the valve disc is gentler than the concave surface of the water pressure area, and each valve disc is respectively covered on each pressure water area . The valve plate is made of rubber material with good elasticity. After long-term use, the material of the valve plate will age, and the fatigue elasticity will decreas...

AI Technical Summary

Problems solved by technology

The valve plate is made of rubber material with good elasticity. After long-term use, the material of the valve plate will age, and the fatigue elasticity will decrease, resulting in a decrease in the recovery elastic force, which cannot guarantee the sealing effect, and the sealing reliability will decrease, so that the water in the low pressure area Reverse flow, or leakage of water into high pressure areas

[0004] In addition, the valve plate of the piston valve is installed on the corresponding position of the valve seat through pins. Since this installation method also needs connecting parts such as pins, the installation process is more complicated, and it is fixed by pins, which is unreliable. There is loose phenomenon
