Rubber Lined Butterfly Valve
Introduction:
Rubber lined butterfly valve, as a component used to realize on-off and flow control of pipeline system, has been widely used in petroleum, chemical industry, metallurgy, hydropower and many other fields. In the well-known butterfly valve technology, the sealing form is mostly the sealing structure, and the sealing materials are rubber, PTFE, etc. Due to the limitation of structural characteristics, it is not suitable for high temperature, high pressure, corrosion resistance, wear resistance and other industries. The existing advanced butterfly valve is a tri eccentric metal hard seal butterfly valve. The valve body and valve seat are integral components, and the sealing surface layer of valve seat is welded with heat resistant and corrosion resistant alloy materials. The multi-layer soft laminated seal ring is fixed on the valve plate. Compared with the traditional butterfly valve, this butterfly valve has the advantages of high temperature resistance, easy operation, no friction when opening and closing, and follows the torque of the transmission mechanism when closing.
Characteristic:
1. New and reasonable design, unique structure, light weight, quick opening and closing.
2. Small operating torque, convenient operation, labor saving and dexterous.
3. It can be installed in any position and is convenient for maintenance.
4. The sealing element can be replaced, and the sealing performance is reliable to achieve zero leakage of two-way sealing.
5. The sealing material has the characteristics of aging resistance, corrosion resistance and long service life. Standards adopted
