Problems solved by technology

At present, the valve plate of the existing butterfly valve will be subject to strong impact when it is closed. After a long time, the valve plate will be damaged and the use effect of the butterfly valve will be affected. At the same time, the handle is not easy to disassemble, and the handle may be accidentally touched during use.

Abstract

The invention discloses a butterfly valve structure with a buffering function. The butterfly valve structure comprises a valve body; the inner bottom of the valve body is rotatably connected with a valve shaft which penetrates through the valve body; the side wall of the valve shaft is fixedly connected with a valve plate, and grooves are symmetrically formed in the two sides of the valve plate; first connecting rods are symmetrically fixedly connected into the two grooves correspondingly; the end, away from the valve plate, of each first connecting rod is rotatably connected with a lever; oneend of each lever is rotatably connected with a second connecting rod; the second connecting rods located in the two grooves are fixedly connected with buffer plates jointly; the ends, away from thesecond connecting rods, of the levers are connected to the inner walls of the grooves through first springs; and the other ends, away from the second connecting rods, of the levers are connected to the side walls of the buffer plates through second springs. The buffer plates are arranged on the surface of the valve plate, impact damage to the valve plate is relieved, the service life is prolonged,and a handle is easy to disassemble, so that mistaken touch during using is avoided.

Description

technical field [0001] The invention relates to the technical field of valve bodies, in particular to a butterfly valve structure capable of buffering. Background technique [0002] Butterfly valve, also known as flap valve, is a regulating valve with simple structure, which can be used for switch control of low-pressure pipeline medium. A kind of valve, the valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. At present, the valve plate of the existing butterfly valve will be subject to a strong impact when it is closed. After a long time, the valve plate will be damaged and the use effect of the butterfly valve will be affected. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a butterfly valve structure that can be buffered. The surface of the valve plate is provided with a buffer...
