Sanitary Diaphragm Valve can be applied to a variety of fluid control needs
The sanitary diaphragm valve is equipped with a flexible diaphragm or a combined diaphragm in the valve body and the valve cover, and its closing part is a compression device connected to the diaphragm. The valve seat can be weir-shaped or the pipe wall of the straight-through flow channel. The advantage of the sanitary diaphragm valve is that its operating mechanism is separated from the medium passage, which not only ensures the purity of the working medium, but also prevents the possibility of the medium in the pipeline impacting the working parts of the operating mechanism.
The sanitary diaphragm valve consists of a sanitary diaphragm valve and an actuator. It uses compressed air as a power to regulate the flow of fluid media in the process pipeline. Due to the use of a valve body with a corrosion-resistant lining and a corrosion-resistant diaphragm, a stuffing box-free structure, a throttling element as an elastic diaphragm, and a smooth valve body flow channel, the film diaphragm valve has the advantages of small negative force, large flow, no leakage, convenient and reliable, fireproof and explosion-proof, and is widely used in industrial automation systems. Flow regulation of strong acid, strong alkali, strong corrosion, high viscosity, grain-containing, fiber-containing, toxic and non-polluting media.
Working principle of sanitary diaphragm valve:
The closing and opening of sanitary diaphragm valve is realized by the pressure from the pipeline acting on the reinforced rubber diaphragm. When the pressure medium enters the valve control chamber, the diaphragm is pressed down to close the valve channel. When the pressure in the control chamber is discharged to the atmosphere or downstream pipeline, the diaphragm rises and the valve channel is opened. The valve has no valve stem, sealing gasket, directional seat, etc. The only moving part in the channel is the diaphragm, so there is no rust and locking phenomenon, and it has higher stability. A variety of structural forms and control forms can be applied to a variety of fluid control needs.
