Audited Supplier G41J Rubber lined diaphragm valve
Diaphragm valve is a special type of valve with truncation function, and its opening and closing parts are composed of a diaphragm made of steel flap and soft material (rubber and fluorine plastic composite), and the inner cavity of the valve body and the inner cavity of the valve cover are separated to achieve the purpose of truncating the medium in the tube.
Advantages of diaphragm valves
1, simple structure, fewer parts Diaphragm valve is only composed of three main components of the valve body, diaphragm and valve cover assembly.
2, easy to disassemble and maintenance under normal circumstances, the damaged part of the diaphragm valve is the diaphragm, replace the diaphragm, do not remove the valve from the pipeline, just remove the valve cover, replace the diaphragm can be completed in a short time on the site.
3, good sealing performance Because the diaphragm is made of soft materials such as rubber or plastic, it has better sealing, but the mechanical life of the diaphragm is short. The medium in the valve will not leak from the connection of the valve body and valve cover. The upper and lower reaches of the valve can be completely cut off without internal leakage.
4, there is no dead Angle valve body flow channel is streamlined, smooth flow channel, no dead Angle, the medium flowing through the valve can not be deposited in the valve and moldy deterioration, and easy to wash, the flowing medium such as containing fibers or particles will not be stuck.
5, no packing structure diaphragm valve does not need to use packing, non-corrosive to the valve stem, valve cover (because the diaphragm separates the lower valve body from the upper valve cover cavity).
6, wide use can be used for cutting and throttling.
7, corrosion resistance due to the diversity of the lining, so that it has good chemical resistance.
8, suitable for a variety of working conditions diaphragm valve is especially suitable for dangerous chemicals and radioactive fluids. Because the valve does not produce pollution, it is widely used in product processing, pharmaceutical, food, nuclear industry and other industries that do not allow pollution.
