The features of the plastic ball valves

2021-09-20
Plastic ball valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, fast switching, reciprocating and rotating 90 degrees, small driving torque characteristics, for truncation, connect, adjust the line of medium, has good sealing off fluid control features and performance.
Plastic ball valve to transport slurry, accumulation of fluid in the pipe outlet at least.Low pressure, can achieve a good seal.Good regulation performance. Plastic ball valve streamline design, so that fluid resistance loss is small, can be described as an energy saving products.
Stem structure for the pass, after quenching and tempering treatment, has a good comprehensive mechanical properties and corrosion resistance, scratch resistance. Ball valve opening and closing when the stem only for rotary motion without lifting operation, stem packing is not easy to damage, reliable sealing. And the butterfly plate cone pin fixed, extended end to prevent out of design, in order to avoid accidental fracture at the junction of stem and disc when stem collapse. Connections are flanged, wafer connections, welded connections and lugs on the clip connection. Drive the form of manual, worm gear drive, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, remote control and automatic operation can be achieved.
