Electric butterfly valves and hoses are pipe fittings that transport various fluids with pipes as the core elements. Their working nature is to play a compensation role in the connection between pipes, pipes and equipment, and equipment and equipment. Therefore, people often confuse the electric butterfly valve with the hose. In fact, there are some differences in their working principles. In some situations where the electric butterfly valve and hose cannot be replaced each other, the unreasonable design will not get the expected compensation effect.
Definition of electric butterfly valve: if the outer surface of the electric butterfly valve is free of wire or with woven mesh sleeve, the electric butterfly valve is equipped with tie rod, hinge, reinforcing ring and other restraint devices, and it is an annular pipe assembly with a ratio of less than 3.
Electric butterfly valves are often called electric butterfly valves in western countries. Generally, the electric butterfly valve compensates the position movement of the pipeline system caused by temperature difference by its axial expansion or angle change ratio; To absorb the vibration when the equipment is started, stopped or under normal operating conditions.
