Description

Duckbilled welding butterfly valve

Technical Field

The utility model relates to a valve, in particular to duckbilled formula welding butterfly valve.

Background

The butterfly valve is also called a flap valve, is a regulating valve with simple structure, and can be used for the switch control of low-pressure pipeline media. The butterfly valve opening and closing piece is a disc-shaped butterfly plate and rotates around the axis of the butterfly plate in the valve body, so that the opening and closing or adjusting purpose is achieved. The butterfly valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like.

The duckbill butterfly valve is named after the actuator is exactly like a duckbill type, most of the existing duckbill butterfly valves are provided with locking mechanisms, the safety coefficient of the valve is improved through the locking mechanisms, and misoperation is avoided. If the butterfly valve needs to be controlled, the actuator is required to be continuously applied with holding force, and the actuator is rotated to control the valve to open and close. Because the control operation needs to apply continuous gripping force to the actuator in the control process, when the valve is debugged and tested or a pipeline system needs to be frequently controlled in the daily maintenance, debugging and testing processes, the frequent and continuous gripping control operation is more strenuous for workers with smaller gripping force. And the locking mechanism is unlocked by gripping, so that the safety factor is lower, and misoperation is easily caused, and the invention is developed according to the problems.
