What is the difference between electric butterfly valve and composite electric butterfly valve?
Electric butterfly valve is a common valve element nowadays. Do you know the difference between electric butterfly valve and composite electric butterfly valve? If you don't know, let's take a look at the introduction of Dongfeng's article.
Electric butterfly valve: It is a kind of high elastic body with ordinary manufacturing materials. The butterfly valve has a small elastic modulus and a large elastic deformation after being loaded to absorb shock and oscillation. It can bear multi-directional loads at the same time, but its high temperature resistance and oil resistance are worse than those of steel butterfly valves. It can be made of oil resistant if there are special requirements. This product has good shock absorption effect, small resonance field, long life span, low cost, cold resistance, good air tightness, waterproof, electrical insulation, and is the best choice for shock absorption.
Composite butterfly valve: it is composed of metal spiral butterfly valve and high-quality vulcanization wrapped outside. Integrating the advantages of metal butterfly valve and butterfly valve, it overcomes the shortcomings of metal butterfly valve, such as high rigidity, high working noise, small bearing capacity, poor shape and mechanical stability. It has advantages of higher load and large deformation, better noise reduction effect of valve, stable operation, short resonance range, etc. In general, compared with butterfly valve, the former is limited by the shape of metal screw butterfly valve, with high linearity requirements and heavy weight, but its large load bearing capacity is not comparable to pure butterfly valve.
