Polytetrafluoroethylene Proportional Butterfly Valve
working principle
The butterfly valve is a kind of valve that uses a disc-type
opening and closing member to reciprocate around 90 ° to open,
close or adjust the flow of medium. Butterfly valves are not only
simple in structure, small in size, light in weight, low in
material consumption, small in installation size, small in driving
torque, easy in operation and fast, but also have good flow
adjustment function and close sealing characteristics at the same
time. One of the fastest valve varieties. Butterfly valves are
widely used. The variety and number of its use is still expanding,
and it is developing towards high temperature, high pressure, large
diameter, high sealing, long life, excellent adjustment
characteristics, and multi-function of one valve. Its reliability
and other performance indicators have reached a high level.
With the application of chemically resistant synthetic rubber on
butterfly valves, the performance of butterfly valves has been
improved. Because synthetic rubber has the characteristics of
corrosion resistance, erosion resistance, dimensional stability,
good resilience, easy forming, and low cost, and can choose
different properties of synthetic rubber according to different use
requirements to meet the working conditions of butterfly valves.
Because polytetrafluoroethylene (PTFE) has strong corrosion
resistance, stable performance, not easy to age, low friction
coefficient, easy to form, stable in size, and can be filled and
added with appropriate materials to improve its comprehensive
performance, get better strength, friction The sealing material of
butterfly valve with lower coefficient overcomes the limitation of
synthetic rubber, so polymer polymer material represented by
polytetrafluoroethylene and its filling modified material have been
widely used in butterfly valve, so that the performance of
butterfly valve It has been further improved to produce butterfly
valves with a wider temperature and pressure range, reliable
sealing performance and longer service life.
