Sanitary Diaphragm Valves Meet The High Requirements Of Hygiene And Are Used In Wineries
Sanitary Diaphragm Valve is a valve used in the sanitary field, commonly used in industries such as food, pharmaceuticals and biotechnology. It has a special design and material selection to ensure the hygienic and pollution-free flow of products. It is usually made of stainless steel or other corrosion-resistant materials, and is easy to clean and leak-free. Its structure includes two isolation diaphragms, which isolate the fluid when the valve is closed, effectively preventing cross contamination. This valve is widely used in process control systems that require a high level of hygiene to ensure product quality and safety. It refers to valve fittings used in places with high requirements for hygiene levels in industries such as pharmaceuticals and food. Generally, it is purchased by pharmaceutical factories or food factories for maintenance and configuration of related equipment. The purchasers are basically pharmaceutical and food equipment system integrators and wholesale buyers, etc.
Sanitary diaphragm valves are used to take liquids such as wine and vinegar. It includes two parts, the upper part is the opening and closing plate, and the lower part is the main body. The main body consists of a cover, a main shell and a valve core. A vent is provided on the wall of the liquid outlet pipe of the main shell. One end of the vent is connected to the vent pipe, and the other end of the vent is connected to the atmosphere. A lifting rod is fixed in the valve core of the product, and a spring seat is provided on the valve core, and a spring is placed on the spring seat. A through hole is opened in the center of the top of the cover of the product. The opening and closing plate is placed on the cover of the main body, and the opening and closing plate is connected to the lifting rod. A handle and a vent plug are fixed on the opening and closing plate. The container is usually closed and isolated from the air to maintain the original taste of the condiment and extend the storage time. When discharging the liquid, the required air can be filled in at the same time to make the discharge smooth. The valve has a simple structure, is easy to make, has good sealing performance and is easy to operate.
The sanitary diaphragm valve is remotely controlled by a drive device or manually operated by a handle. There are three standards for the drive device: normally closed, normally open and air-to-air. It has the advantages of simple structure, beautiful appearance, quick disassembly and assembly, flexible operation, small fluid resistance, safe and reliable use. It is suitable for the control of water, gas, oil and corrosive media in chemical, petroleum, metallurgy, water heating, food, medicine and other industries.
Sanitary diaphragm valve can be remotely operated by a pneumatic head or manually operated by a handle. It is very suitable for the control and opening/closing tasks of pipeline fluid. It is widely used in sanitary brewing, dairy products, beverages and other food industries as well as in the pharmaceutical field under aseptic conditions.
Working principle of sanitary diaphragm valve: The close fit between the valve body and the diaphragm provides valve body sealing and valve seat sealing, ensuring the isolation of the internal and external environments of the pipeline, so it is suitable for aseptic processes. Opening and closing are achieved by the up and down movement of the valve stem. When the stem is in the upper position, the spherical diaphragm bends upward to form a conducting state. When the valve stem moves from top to bottom, it drives the valve core to bend the diaphragm, forcing the diaphragm to be close to the valve seat area or, closing the path to the pipeline fluid. It can be operated manually, pneumatically, or controlled by an intelligent controller. It can be operated remotely by a pneumatic head or manually by a handle. It is very suitable for pipeline fluid control and on/off tasks.
