butterfly valve
Butterfly valve is a valve that uses a circular butterfly plate as the opening and closing element and rotates with the valve stem to achieve the opening and closing action. The butterfly valves produced by Shanghai Meiyan Yi Pump Valve have the advantages of simple design structure, rapid opening and closing, small pipeline area occupation, light weight, and small opening and closing torque. According to different sealing requirements for butterfly valves, they can be designed to have functions of cutoff, adjustment, or both cutoff and adjustment. The maximum diameter of the butterfly valve of Shanghai Meiyan Yi Pump Valve can reach 6000mm. Large diameter butterfly valves or butterfly check valves are generally equipped with slow closing damping devices to prevent water hammer from causing valve accidents. The butterfly plate of butterfly valves has various structures, mainly including midline butterfly valves and eccentric butterfly valves. And the sealing forms are divided into soft sealed butterfly valves, hard sealed butterfly valves, as well as clamp butterfly valves, flange butterfly valves, butt welded butterfly valves, electric butterfly valves, pneumatic butterfly valves, hydraulic butterfly valves and other different models and specifications. The main difference between the center line butterfly valve and the eccentric butterfly valve lies in the position of the valve stem. The fluid resistance of the center symmetrical plate is relatively small, but the sealing surface is prone to abrasion and leakage, so it is mostly used for flow regulation; The sealing performance of the inclined plate is good, but it is difficult to process; The sealing performance of the offset plate is also good, and it is easy to process and maintain, but the fluid resistance is relatively high. The following product images are for selection reference only.
