Butterfly valve use occasions

Butterfly valve, also known as flap valve, is a simple structure of the control valve, but also can be used for low-pressure pipeline medium switch control. The use of butterfly valve: butterfly valve widely used for flow control. As the butterfly valve in the pipeline pressure loss, about three times the gate valve. Therefore, the choice of butterfly valve, piping system should be fully taken into account the impact of pressure loss, but also should consider the firmness of the disc medium to withstand the pressure of the pipe when closed and the elastic temperature of the seat material under high temperature can withstand the operating temperature limit. Butterfly valve structure length and overall height is relatively small, open, close the speed block, with good fluid control features, its architecture is the most suitable principle for the production of large-caliber valves. When a butterfly valve is required for control flow, it is of paramount importance that the correct size and type of butterfly valve be selected so that it works more efficiently. In general, in the throttling, regulation and control of mud medium, requiring short structural length, opening and closing speed. Low-voltage cut-off, it is recommended to use the butterfly valve. 1, in the two-bit regulation, narrow mouth of the channel, low noise, cavitation and gasification phenomenon, a small amount of leakage to the atmosphere, with corrosive media, the optional butterfly valve. 2, In special conditions, the throttling regulation or strict requirements, or severe wear and tear, low temperature conditions, such as the use of butterfly valves, the need to use special design metal seal with the adjustment device of the three eccentric or double eccentric butterfly valve. 3, metal to metal surface seal three eccentric butterfly valve except as a large pressure swing adsorption gas separation device program control valve, but also can be widely used in petroleum, petrochemical, chemical, metallurgy, electric power and other fields, gate valve, globe valve, etc. is good replacement product. 4, the middle line of the butterfly valve is required for fresh water, sewerage, seawater, salt water, steam, natural gas, food, medicine, oil and so on, which are required to be completely sealed, gas leaked into another, with high life expectancy and working temperature of -10-150 degrees Acid and alkali and other pipelines. 5, metal to metal wire seal Double eccentric butterfly valve for urban heating, gas supply, water supply and gas, oil, acid and other pipelines, as the regulation and closure devices. 6, soft eccentric butterfly valve for dust removal pipeline bidirectional opening and closing and regulation, are widely used in metallurgy, light industry, electricity, petrochemical systems, gas pipelines and waterways.

Chuck Flap Wheel
