进口开关型气动蝶阀mported switch type pneumatic butterfly valve

Product Description:

The utility model comprises a pipeline, one side of the pipeline is fixedly connected with a first flange, the side of the pipeline away from the first flange is fixedly connected with a second flange, the middle of the top of the pipeline is fixedly connected with a support pipe, the top of the support pipe is fixedly connected with a valve box, and the side of the valve box close to the first flange is fixedly equipped with a first sealing cover. By setting the valve box, the air inlet is connected with the air pump, and the exhaust port is connected with the external exhaust equipment. The air is supplied to the inside of the air chamber through the air pump, and then the first piston is pushed to move to the middle of the valve box. When the first piston moves, the rack at both ends will drive the gear to rotate around the axis of the connecting rod. When the connecting rod rotates, the fixed rod will rotate to open. When it needs to be closed, The gas inside the gas chamber is discharged through the exhaust port, so as to achieve the effect of convenient use.

进口开关型气动蝶阀characteristic:

Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a pneumatic valve that uses the circular butterfly plate rotating with the valve stem for opening and closing to realize the action. It is mainly used as block valve, and can also be designed to have the function of regulation or section valve and regulation. Butterfly valve is more and more used in low-pressure large and medium diameter pipeline.
