Structure and working principle of diaphragm valve:
The diaphragm valve structure is a special form of shut-off valve, and its opening and closing member is a diaphragm made of soft material, which separates the valve body cavity from the valve cover cavity. Diaphragm valve is actually just a "clamp" valve, an elastic and flexible diaphragm connected to a compression element with a screw. The compression element is operated by the valve stem to move up and down. When the compression element rises, the diaphragm is raised, creating a passage. When the compression element falls, the diaphragm is pressed against the valve body weir (if it is a weir valve) or the bottom of the contour (if it is a straight through valve). Diaphragm valve is suitable for switching and throttling purposes.The main Diaphragm Valve product names of China Diaphragm Valves Network include: Fluorine Diaphragm Valve,Engineering Plastic Diaphragm Valve,Flange Fluorine Lined Butterfly Valve,Flange Fluorine Lined Diaphragm Valve,Flange Fluorine Lined Globe Valve,Flange Fluorine Lined Plug Valve,Flange Wedge Fluorine Lined Gate Valve
The reason for the structural design of the diaphragm valve itself is particularly suitable for ultra pure media or heavily polluted, highly viscous liquids, gases, corrosive or inert media. When combined with control equipment, diaphragm valves can better replace other traditional control systems, especially suitable for solid and easily contaminated inert media. The product is mainly used in the biopharmaceutical, food, and industry sectors; In the industrial water treatment of industries such as power, chemical, electroplating, etc., diaphragm valves are also used in the production of semiconductor wafers. Diaphragm valves are particularly suitable for transporting corrosive and viscous fluids, such as mud, food, drugs, textile adhesives, etc. Because the operating mechanism of diaphragm valves in pipelines is not exposed to the transport fluid Diaphragm Valve Products, they are non polluting and do not require packing. The valve stem packing part is also unlikely to leak.
Working principle of diaphragm valve: The closing and opening of diaphragm valve is achieved 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 and the valve channel is closed. When the pressure in the control chamber is discharged to the atmosphere or downstream pipeline, the diaphragm rises and the valve channel is opened. Valves do not have valve stems, gaskets, directional seats, etc. The only component that moves in the channel is the diaphragm, so there is no rusting or locking phenomenon, and it has higher stability. Multiple structural and control forms, suitable for various fluid control needs.
