A butterfly valve is a valve in which a closing member (valve or disc) is a disc that rotates around the valve shaft to open and close, and is mainly used for cutting and throttling on the pipe. The butterfly valve opening and closing member is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjusting. The butterfly valve is normally less than 90° from full opening to full closing. The butterfly valve and the butterfly rod have no self-locking capability. For the positioning of the butterfly plate, a worm gear reducer is added to the valve stem. The use of a worm gear reducer not only enables the disc to have a self-locking capability, but also stops the disc at any position and improves the valve's operating performance.
Butterfly valves, whether manually or automatically, can be used in fluid product applications in the food processing, pharmaceutical and chemical industries. The utility model has the advantages of simple structure, beautiful appearance, quick assembly and disassembly, quick switch, flexible operation, small fluid resistance and safe and reliable use. Replace the flange, pipe thread, trapezoidal thread and other shortcomings caused by the traditional connection method in China. Can be used with a variety of actuators. The utility model has the advantages of compact structure, convenient assembly and disassembly, and the like.
All steel parts are made of acid-resistant stainless steel, and the seals are made of food silicone rubber or PTFE, which meets food hygiene standards. It is widely used in many industries such as food, brewing, beverage, dairy, fine chemical pharmaceutical and bioengineering.
The mechanical performance advantages of sanitary manual butterfly valves have the following points:
After the introduction of Xiaobian, what are the main characteristics of the sanitary manual butterfly valve , do you understand? More technical articles on Wenzhou Rifeng Technology Co., Ltd.
What are the main characteristics of sanitary manual butterfly valves?
The sanitary manual butterfly valve uses standard electronic polishing, and the smooth surface ensures cleanness and no media accumulation area, which will not cause potential pollution. Quickly disassemble the valve, making the valve open and quick and easy to repair, reducing process downtime. The device is a valve that uses a circular disc as the opening and closing member and rotates with the valve stem to open, close and adjust the fluid passage. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, and easy to operate.
1. Butterfly valve rubber sealing ring and valve plate are imported, which guarantees the performance and service life of the butterfly valve.
2. The high-precision CNC lathe finishing valve body ensures the reliable interchangeability of the butterfly valve, eliminating the trouble of not being able to guarantee the performance of the rubber due to the replacement of the rubber.
3, the valve stem is fitted with a nylon sleeve, which reduces the friction and thus opens and is flexible and easy.
4. The steel parts are made of stainless steel, the rubber is made of food rubber, and the sanitary quality is high.
5. The diameter of the valve body and the inner diameter of the pipe are narrow. The valve plate with a streamlined shape is in the same direction as the fluid. The flow rate is large and the resistance is small, and no material accumulates.
6. The handle adopts the pulling type and the pulling type, which can withstand large operating torque and is not easy to be broken.
7. The opening and closing range is 0~90 degrees, which can be fixed at every 15 degrees, with adjustable, quick opening and closing, and convenient operation.
8. The valve body is detachable and connected, with simple structure and convenient maintenance.
9, the shape is light and beautiful, the surface is bright and not sticky, no burr tied hands.
10. After strict strength and sealing test, quality is guaranteed.
11. Sampling is carried out with a fatigue life test of not less than 30,000 times to ensure its service life.
