What is a high performance butterfly valve - China High Performance Butterfly Valve Manufactures

Oct 27,2022

High-performance butterfly valve, also known as flap valve, is a kind of regulating valve with simple structure. A high-performance butterfly valve that can be used for medium switching control in low-pressure pipelines, which means that the closing member (butterfly plate or butterfly plate) is a butterfly plate, which rotates around the valve shaft to realize opening and closing. Butterfly valve is a kind of valve. Valves can be used to control the flow of various fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Mainly play the role of cutting and throttling the pipeline. The opening and closing part of the high-performance butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.

Wafer Type High Performance Double Offset Butterfly Valve

The high-performance butterfly valve is a valve that uses the reciprocating motion of the disc type opening and closing member to about 90° to open, close or adjust the flow of the medium. It not only has simple structure, small size, light weight, few consumables, small installation size, small driving torque, simple and quick operation, but also has good flow regulation and closing sealing characteristics. At the same time, it is also one of the valve varieties that has developed rapidly in the past ten years. High-performance butterfly valves are widely used. The variety and number of its uses are constantly expanding, and it is developing in the direction of high temperature resistance, high pressure, large diameter, high sealing performance, long life, excellent adjustment characteristics, and one valve for multiple purposes. Its reliability and other performance indicators have reached a high level.

Applying chemically resistant synthetic rubber to high performance butterfly valves can improve butterfly valve performance. Since synthetic rubber has the characteristics of corrosion resistance, erosion resistance, dimensional stability, good resilience, easy molding, and low cost, synthetic rubber with different properties can be selected according to different application requirements to meet the working conditions of high-performance butterfly valves.

Because PTFE has the characteristics of strong corrosion resistance, stable performance, not easy to age, low coefficient of friction, easy to form, and dimensionally stable, it can be filled and added with appropriate materials to improve its comprehensive performance, so as to obtain better strength and friction. coefficient. Low-performance butterfly valve sealing materials overcome the limitations of synthetic rubber. Therefore, polymer materials represented by polytetrafluoroethylene and its filling and modified materials have been widely used in high-performance butterfly valves, thereby improving the performance of high-performance butterfly valves.
