According to the deformation mode after being loaded, the electric butterfly valve can be divided into bag type electric butterfly valve, membrane type electric butterfly valve and hybrid electric butterfly valve. Among them, the membrane electric butterfly valve includes the constrained membrane electric butterfly valve and the free membrane electric butterfly valve. Since the free film electric butterfly valve has the advantages of light weight, good mechanics and performance, this type of air butterfly valve is widely used as the secondary suspension of bogie in high-speed EMUs in China. The electric butterfly valve shown in Figure 1 is a free film electric butterfly valve. An orifice is arranged in the center of the lower cover plate of the free film electric butterfly valve, and the lower end of the orifice is connected with an additional air chamber. Electric butterfly valve: a butterfly valve made of the compressibility of air in a closed container. It is widely used in self-adjusting air suspension of commercial cars, buses, rail vehicles, machinery and building bases. The electric butterfly valve technology is applied to the valves of industrial equipment, which effectively improves the working efficiency and safe service life of the equipment. Dongfeng electric butterfly valve does not have an internal control rod, piston or sliding sealing device like the ordinary cylinder device, which greatly reduces the cost of using pneumatic or hydraulic cylinders and wins more economic benefits for customers.
characteristic:
● Low cost and wide range of specifications
● Long service life, no need for maintenance and lubrication, no need for internal lever or piston
● Soft medium without friction effect
● Bending capacity, side load capacity, compact original height
