Description

Technical Field

[0001] The utility model relates to the field of elastic ball type butterfly valves, in particular to an elastic ball type butterfly valve. Background Art

[0002] A butterfly valve, also known as a valve, is a reciprocating fluid control device. It has many functions. It can control the pressure and flow of the fluid. It can be used to control the flow of liquid or gas out of the pipeline to avoid damage to the pipeline caused by excessive pressure. The butterfly valve can be used to adjust the flow rate and can effectively control the flow and pressure of the fluid in the system. The butterfly valve can prevent the leakage of liquid or gas in the pipeline and more effectively protect the equipment and pipeline system.

[0003] In the prior art, the valve seat and the butterfly plate of a traditional butterfly valve mostly adopt a cylindrical inner plane fit. This structural fit has certain disadvantages. The butterfly plate and the valve seat cannot fit too tightly. If the fit is too tight, it is difficult to open and close the valve. Without force, it is difficult to open the valve or completely close the valve. When the valve is closed with force or when it is hit, the butterfly plate is easily deformed and damaged, and its service life is short. Therefore, those skilled in the art provide an elastic ball butterfly valve to solve the problems raised in the above background technology. Utility Model Content
