working principle: The sanitary quick-install butterfly valve is a stainless steel valve that uses a circular butterfly plate as an opening and closing part and rotates with the valve stem to open, close and adjust the fluid passage. The butterfly plate of the sanitary quick-install butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the stainless steel butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is fully opened.
Sealing of sanitary quick-install butterfly valve: The sanitary quick-install butterfly valve is a centerline stainless steel soft-sealed butterfly valve. Its sealing principle is to ensure that the sealing surface of the sanitary quick-install butterfly valve has a suitable surface roughness value during processing. Synthetic rubber valve The seat forms a suitable surface roughness value for the sealing surface during compression molding. When the stainless steel butterfly valve is closed, through the rotation of the valve plate, the outer sealing surface of the valve plate squeezes the synthetic rubber valve seat, so that the synthetic rubber valve seat produces elastic deformation. The elastic force is used as the sealing pressure to ensure the sealing of the valve.
Application: Sanitary fast-installed butterfly valve is specially used in dairy products, food, pharmaceutical, beer, cosmetics and other industrial fields.
Concept: The sanitary butterfly valve is a stainless steel valve that uses a circular butterfly plate as an opening and closing part and rotates with the valve stem to open, close and adjust the fluid channel. The valve is not only simple in structure, small in size, light in weight, and low in material consumption. , The installation size is small, and the driving torque is small, the operation is simple and fast, and it also has a good flow adjustment function and closing and sealing characteristics. It is the dominant valve form in the use of large and medium caliber, medium and low pressure.
Function and application: The sanitary butterfly valve adopts standard electronic polishing, and the smooth surface ensures cleanness, no medium accumulation area, and no potential pollution. All steel parts are made of acid-resistant stainless steel, and the seals are made of food silicone rubber or polytetrafluoroethylene, which meets food hygiene standards. It is widely used in many industries such as food, brewing, beverage, dairy products, fine chemical pharmacy and biological engineering.
Operation: The butterfly plate is installed in the diameter direction of the pipeline. In the cylindrical channel of the sanitary valve, the disc-shaped butterfly plate rotates around the axis. The angle of rotation is within the range of 0°~90°. When the rotation reaches 90°, the valve will It will enter the fully open state and needs to be installed according to the manufacturer’s installation instructions. The heavy butterfly valve needs a firm foundation.
Medium: Sanitary butterfly valve is suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, oil that require complete sealing, zero gas test leakage, high life expectancy, and operating temperature of 10℃ to 150℃. Products and various acid-base and other thin-walled pipelines. (Ie liquid, gas, oil, various highly corrosive chemical media)
Product features: 1. Novel and reasonable design, unique structure, light weight, and rapid opening and closing. 2. Small operating torque, convenient operation, labor-saving and smart. 3. It can be installed in any position and is convenient for maintenance. 4. The sealing material has the characteristics of anti-aging, corrosion resistance and long service life.
