Manufacturing principle of electric butterfly valve
As we all know, electric butterfly valves are all made of round section steel wire, and the ratio of the uniform diameter of butterfly valves to the diameter of steel wire is equivalent. The butterfly valve index (also called the winding ratio) is a butterfly valve made of rectangular section steel wire. The butterfly valve index refers to the uniform diameter of the butterfly valve, which is equivalent to the ratio of the width of the data on the side perpendicular to the butterfly valve axis.
In the practical application of electric butterfly valve, the elasticity index of the butterfly valve inside the low-frequency damping electric butterfly valve is usually selected between 4N. The smaller the steel wire diameter, the higher the elasticity value can be obtained, but it is better to select between 7 and 13. The smaller the elasticity index value of the butterfly valve in the electric butterfly valve of the butterfly valve, the greater the deformation of the wire and the more accurate the winding. During the operation, the inner side of the butterfly valve data is prone to generate excessive stress, which affects the fatigue strength of the data; However, if the elasticity index value of the butterfly valve in the electric butterfly valve of the butterfly valve is too small, the butterfly valve will tend to be unstable. Chinese national standard GB1239-62 stipulates that the butterfly valve index value of ordinary cylindrical screw butterfly valve is between 4 and 16. For example, in the electric butterfly valve of butterfly valve, the butterfly valve is composed of two metal wires with the same diameter, which are wound into a butterfly valve with the same number of turns and height. The elasticity of the butterfly valve can be judged from the butterfly valve index value. The smaller the elasticity index value of the butterfly valve in the electric butterfly valve of the butterfly valve, the greater the tension of the electric butterfly valve of the butterfly valve, and the harder the butterfly valve. On the contrary, the larger the butterfly valve index, the smaller the tension of the butterfly valve electric butterfly valve, and the softer the butterfly valve.
As long as the butterfly valves match each other, the electric butterfly valve of the butterfly valve can play its best role, which is why there is so much information to understand and so many details to understand when selecting butterfly valves.
