1, butterfly valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, fast switching, 90 degree reciprocating rotary, the driving characteristics of torque, for the truncated, switched on, adjust the line of medium, has good sealing off fluid control features and performance.
2, butterfly valve to transport slurry, accumulation of fluid in the pipe mouth at least. Low pressure, can achieve a good seal. Good regulation performance.
3, streamline design of the disc, the fluid resistance loss is small, it is a kind of energy-saving products.
4, pole structure of the stem to pass, after quenching, with good mechanical properties and corrosion resistance, scratch resistance. Butterfly valve opening and closing only when the valve stem rotates without lifting operation, easy to damage the stem packing, sealing and reliable. And the butterfly plate taper pin fixed, extended end to prevent out of design, in order to avoid accidental fracture junction in the stem and disc collapse when the valve stem out.
5, connections are flanged, wafer connections, welded connections and lugs on the clip connection.
Drive in the form of manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic linkage executing mechanism, can realize remote control and automation.
1, convenient opening and closing rapidly, fluid resistance small, labor saving, can often operate.
2, has the advantages of simple structure, small size, short length of the structure, small volume, light weight, suitable for large diameter valves.
3, to transport slurry, accumulation of fluid in the pipe mouth at least.
4, low pressure, can achieve a good seal.
5, good regulation performance.
6, fully open the valve seat channel effective flow area is larger, the fluid resistance is
