The structure of the electric butterfly valve is a piston rod inserted into the cylinder, which is filled with oil. The throttle valve has a throttle valve on the piston, so that the oil in the two parts of the space separated by the piston can supplement each other.
Damping force is generated when viscous fluid passes through the orifice. The smaller the orifice, the greater the damping force, the greater the oil viscosity, and the greater the damping force. If the size of the throttle valve is constant, the damping will affect the absorption of the electric butterfly valve when it works very fast. Therefore, establish a disc valve butterfly valve at the outlet hole. When the pressure changes, the valve opens, the orifice opening becomes larger, and the damping is smaller. Since the piston is bidirectional, there are butterfly valves on both sides of the piston, called compression valves and extension valves.
Electric butterfly valve is a special element used to reduce or eliminate shaking and shock. Electric butterfly valves are usually made of materials and metal butterfly valves. In our factory, electric butterfly valves commonly used in electronic equipment are electric butterfly valves and metal butterfly valves. The electric butterfly valve is used as the elastic element of the electric butterfly valve, with Jinqu as the support framework.
Due to the use of materials, this electric butterfly valve has greater damping, which can effectively absorb the shivering with higher frequency. When the shivering frequency string passes through the common seismic area, it will not have too large amplitude. It can accept instantaneous large deformation, so it can accept impact force and has better shock isolation function. The electric butterfly valve of butterfly valve uses metal materials as elastic elements (such as butterfly valve steel plate and steel wire). The common ones are cylindrical butterfly valve and conical butterfly valve. The benefit of this electric butterfly valve is that it is insensitive to the environment response, and is suitable for harsh environments such as high temperature, cold, oil pollution, etc.
The operation function is stable and not easy to be aged, and the stiffness change planning can be very soft or hard. The pneumatic electric butterfly valve is a new type of electric butterfly valve opened since the 1960s. Its structural feature is that a floating piston is installed at the lower part of the cylinder barrel, and a sealed gas chamber formed by the floating piston and one end of the cylinder barrel is filled with high-pressure nitrogen.
