Tin bronze butterfly valve cutting and throttling function
- Jun 02, 2018 -

Tin bronze butterfly valve is also called flap valve to a certain extent. To a certain extent, it is a simple structure regulating valve. When it is used, the butterfly valve that can be directly used for low pressure pipeline medium switching control is the closing part (valve or The disc is a disc that rotates around the valve shaft to open and close. The valve can be used to control air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media. Type of fluid flow.


Tin bronze butterfly valve mainly plays the role of cutting off and throttling in the pipeline. In the process of operation, the butterfly valve opening and closing part is a disc-shaped butterfly plate, and can be wound in the valve body around its own during operation. The axis rotates so that it can effectively achieve its opening and closing or adjustment purposes.


The butterfly plate is driven by the valve stem. If it turns 90°, it can complete one opening and closing. By changing the deflection angle of the disc, you can control the flow of the media. Operating conditions and media: Butterfly valves are suitable for generating furnaces, gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation, environmental protection, building water supply and drainage, and other engineering systems. The flap or butterfly plate is a disk, which rotates around the valve shaft to open and close a valve. It mainly acts as a cutting and throttling in the pipeline.


The opening and closing member of the tin bronze butterfly valve is a disk-shaped butterfly plate. During operation, the valve body rotates around its own axis, so that the purpose of opening and closing can be achieved, and the butterfly valve is fully opened to full during operation. Off is usually less than 90°. The butterfly valve and the butterfly rod do not have self-locking capability. To position the butterfly plate, a worm gear reducer is installed on the valve stem. The use of a worm gear reducer not only allows the butterfly plate to have self-locking capability, allows the butterfly plate to stop at any position, but also improves the valve's operating performance.
