Dongfeng electric butterfly valve is a kind of precisely designed fiber bellows, which does not provide force or support load, but fills compressed air into the air compressor to realize force transmission and elastic effect. According to the requirements for stroke, the electric butterfly valve is generally designed as 1-3 curves, and can be designed and manufactured as 4 or more curves when necessary, Under certain conditions, two electric butterfly valves can also be used together
The electric butterfly valve is nonlinear, and its stiffness changes with the load, so its natural frequency almost remains unchanged under any load, so that the butterfly valve device has almost unchanged performance; It has good performance of absorbing high-frequency vibration and sound insulation; It can bear axial load and radial load at the same time. Through the adjustment of internal pressure, different bearing capacities can be obtained. Therefore, it can meet the needs of various loads
Within the effective stroke, the rigidity, height, cavity volume and bearing capacity of the electric butterfly valve are adjusted by increasing or decreasing the inflation pressure. At the same time, its rigidity, height, cavity volume and bearing capacity will change smoothly and periodically with the increase or decrease of the load, thus realizing the flexible transmission of bearing capacity Effective adjustment of stroke and efficient control of vibration amplitude and vibration load. Air chamber can also be attached to realize automatic adjustment
