The Introduction of Stainless Steel Butterfly Valves
At present, as a component which used to piping system implement off and flow control,stainless steel butterfly valves have been widely used in the petroleum, chemical industry, metallurgy, water and electricity in many areas are extremely broad in application.
In the publicly known stainless steel butterfly valves technology, the seal forms enclosed structure, sealing material for the rubber, PTFE and so on. As the restrictions of the structure, stainless steel butterfly valves are not suited to industries of high temperature, high pressure and corrosion resistance.
The advantages and disadvantages of stainless steel butterfly valves:
1\The advantages of stainless steel butterfly valves:
(1) Open and close easily and quickly, saving, fluid resistance and stainless steel butterfly valves can often operate.
(2) Simple structure, small size and light weight.
(3) Stainless steel butterfly valves can carry mud and leave the least fluid in the pipe.
(4) Low pressure, stainless steel butterfly valves can achieve a good seal.
(5) Regulated performance.
2\Stainless steel butterfly valves defects:
(1) Using the small range of pressure and temperature.
(2) Poor sealing.
According to the form of the structure, stainless steel butterfly valves can be divided into bias plate, vertical plate, inclined plate and the lever type. By sealing form stainless steel butterfly valves can be divided into relatively closed and hard sealed type.
