Industrial Wafer Type Triple Eccentric Hard Seal Butterfly Valve
wafer
Q235A,WCB,CF8,CF8M
1 year
Purpose and functions:
The hard-sealed manual triple-eccentric butterfly valve has a triple-eccentric design structure (multi-layer or elastic sealing structure can be used). This structure ensures that the valve plate seal only contacts the valve seat when it is in the closed position, so there will be no friction or wear, and A torque is generated so that the elastic seal has sufficient compaction performance to ensure uniform contact between the sealing surfaces. It is widely used in various demanding occasions, such as petroleum refining, natural gas mining, chemical industry, power stations, iron and steel metallurgy, urban heating and other medium working conditions.
Features:
There is no friction between the sealing pairs: The sealing pair of the valve is designed using unique geometric principles. There is no friction between the butterfly plate sealing ring and the valve seat during the entire switching process.
Anti-fly-out valve stem: When the connection between the valve stem and the butterfly plate fails during use, the valve stem will not rush out of the valve body and harm the operator.
High temperature resistance: There are no rubber or plastic parts in the entire valve internal structure, and the valve has high temperature resistance.
Bearing protection: The bearings in high-temperature valves are protected by pre-compressed flexible graphite rings. The medium in the pipeline cannot enter the bearings, which improves the valve's anti-jamming ability.
Torque shut-off characteristics: The triple-eccentric butterfly valve relies on torque to shut off, and there will be no over-closing (no limit adjustment required).
Zero leakage: When the valve is closed, the multi-layered metal sealing ring is embedded in the valve seat hole, producing a strong fitting force; when the valve is subjected to a forward pressure test, zero leakage can be achieved.
