Hanger electric butterfly valve (hanging butterfly valve electric butterfly valve) is mainly made of metal butterfly valve, combined with certain damping materials, and has the functions of low frequency, large damping, wide application range, and obvious vibration isolation and noise reduction effect. Hanger electric butterfly valve is a combination of steel butterfly valve and series type vibration isolation and noise reduction element, which is suitable for vibration reduction of various pipelines and fan coil units, fresh air units, variable air volume air conditioning boxes, axial flow fans, etc. The electric butterfly valve of the hanger is easy to install, and the lateral damping block is used to increase the vertical damping coefficient, improve the longitudinal and transverse rigidity, and ensure the normal and safe operation of the equipment.
Dongfeng Electric Butterfly Valve Factory is mainly committed to the development and production of hanging butterfly valve electric butterfly valve (electric butterfly valve), pipeline electric butterfly valve (electric butterfly valve), new damping electric butterfly valve and other products. It is a professional manufacturer of electric butterfly valves in China. Its products are widely used in various pipelines and equipment in industries such as steel, power generation, petrochemical, cement steel and urban heating, It has been applied to key projects in 31 provinces, cities and autonomous regions across the country. Its performance has spread all over the country and is trusted by users
Firstly, the butterfly valve shall meet the following requirements: the radius of the butterfly valve shall be four times greater than the zero point of its height under the rated load; The butterfly valve shall have a certain additional stroke, at least equal to 50% of the rated static deflection; The number of butterfly valve coils shall not be too small, generally not less than six; The butterfly valve manufactured in this way can ensure that the horizontal rigidity of the electric butterfly valve is enough so that the equipment is stable and not prone to toppling, the elasticity is durable, and the lasting vibration reduction capacity is guaranteed. However, the price of the electric butterfly valve of this kind of butterfly valve is often higher.
According to the weight of the water pump, it is reasonable to select the type. Generally, the compression capacity of the butterfly valve after the weight of the electric butterfly valve of the pressure bearing water pump of the butterfly valve should be more than 20 mm, not more than the rated compression capacity of the electric butterfly valve, so as to ensure the best vibration isolation effect of the electric butterfly valve.
