The main advantages of pneumatic butterfly valve flange gas has the advantages of simple structure, small volume and light weight, low cost, pneumatic butterfly valve of the notable features, installed in the upper passage, after the two position five way solenoid valve control easy to operate, but also adjust the flow of medium. Fluid resistance small, medium and large caliber pneumatic butterfly valve fully open when the effective flow area is large, open and close rapidly and 90 to complete the rotation angle plate pulling hoist, because the shaft on both sides of the disc hand medium force are equal, the direction of torque generated on the contrary, the opening and closing torque is small, can achieve a good seal under low pressure butterfly valve, sealing material is nitrile rubber, fluorine rubber, edible rubber, PTFE as the sealing performance is good, the hard seal butterfly valve for the hard and soft laminated metal sheet has advantages of ametal sealandsealthe, both at low temperature, both with excellent sealing performance.
Pneumatic flange butterfly valve, working principle, applicable environment analysis
Butterfly valve plate installed in the direction of the diameter of the pipe. In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees ~90 degrees between, when rotates to 90 degrees, the valve opens the card completely.
Butterfly valve structure is simple, small size, light weight, only by a few parts. The utility model has the advantages of quick opening and closing when rotating 90 DEG, simple operation and good flow control characteristic at the same time. When the butterfly valve is in the fully open position, the butterfly plate thickness is the only resistance when the medium passes through the valve body, so the pressure drop produced by the valve is very small, so the flow control characteristic is better. Butterfly valve with bullet sealing and metal sealing two seal type. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.
Metal sealed valves are generally longer than resilient seals, but they are difficult to seal completely. The metal seal can adapt to higher working temperature, and the elastic seal has the limitation of temperature.
If the butterfly valve is used as a flow control, the main thing is to correctly select the size and type of valve. Butterfly valve structure and principle, especially suitable for making large-diameter valves. Butterfly valves are not only widely used in petroleum, gas, chemical, water treatment and other general industries, but also applied to the cooling water system of thermal power stations.
Working principle of stainless steel pneumatic butterfly valve
Stainless steel pneumatic butterfly valve is used to rotate with the orange do open and close the valve, to enable the action of the pneumatic valve main shut-off valve used to do, can be designed to have a regulation or a section of the valve and control function, the butterfly valve in the low pressure large diameter pipeline on the use of more and more.
