First, Overview
1. Scope of use
Applicable to the furnace, gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system in the transport of all kinds of corrosive, non-corrosive fluid medium pipeline, used to regulate and cut off the flow of media.
2, flange type soft seal butterfly valve features
(1) Novel design structure, small overall size, light weight.
(2) The butterfly plate adopts double eccentric, quick opening and closing, easy operation and labor saving.
(3) No sliding friction between the butterfly plate and the sealing ring, sealing surface damage, long service life, reliable sealing, easy to adjust.
3, flange type hard seal butterfly valve has the characteristics
(1) The butterfly plate seal ring is a hard and soft laminated metal sheet, which has the double advantages of hard metal seal and elastic seal.
It has excellent sealing performance in both low and high temperature conditions.
(2) Adopt the three-dimensional eccentric structure, the valve seat and the butterfly plate almost no friction, with the tighter the sealing function.
(3) The sealing surface of the valve body is made of surfacing stainless steel and cobalt-based hard alloy. The sealing surface is damaged and the service life is long.
(4) Structure, flexible operation, labor saving, convenient, not affected by high and low medium pressure, reliable sealing performance.
