1, the butterfly valve has the characteristics of simple structure, small size, light weight, material consumption, small installation size, rapid switching, 90 ° reciprocating rotation, small driving torque and the like for cutting off, connecting and regulating the medium in the pipeline, Has good fluid control features and close the sealing performance.
2, the butterfly valve can transport mud, the liquid accumulated in the pipe port at least. Under low pressure, a good seal can be achieved. Good regulation.
3, the streamlined design of the disc, the fluid resistance loss is small, can be described as an energy-saving products.
4, stem for the rod structure, after quenching and tempering, there are good comprehensive mechanical properties and corrosion resistance, abrasion resistance. When the butterfly valve is opened and closed, the stem only rotates for the movement without lifting. The packing of the stem is not easily damaged and the seal is reliable. Cone pin with the butterfly plate fixed, the outstretched end of the anti-flush design, so as to avoid accidental fracture stem and disc junction stem collapse.
5, the connection flange connection, on the folder connection, butt connection and lugs folder connection.
Drive in the form of manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic linkage and other implementing agencies, enabling long-distance control and automation.
