Shanghai Dongfeng Electric Butterfly Valve Manufacturing Co., Ltd., located in Shanghai Baoshan Development Zone, is a modern professional vibration and noise reduction enterprise integrating design, development, manufacturing, sales, installation and maintenance. Since its establishment, after years of development and independent innovation, the company has grown rapidly in the fierce market competition. Over the years, the company has been relying on the design institute, relying on the advantages of scientific research and production consortium, and constantly adopting new technologies and processes. Shanghai Dongfeng Electric Butterfly Valve is a professional manufacturer of shock absorbers in China. It is mainly engaged in the development and production of butterfly valve electric butterfly valve, damping damper, air-conditioning electric butterfly valve, electric butterfly valve, suspended butterfly valve damper, pipeline electric butterfly valve, fan electric butterfly valve and other series of products, which are widely used in steel, power generation, petrochemical All kinds of pipes and equipment in cement, steel, urban heating and other industries have been applied in national key projects, with achievements all over the country, and are trusted by users.
The butterfly valve shall meet the following conditions: the radius of the butterfly valve damper shall be four times greater than the zero point of its height under the rated load; Butterfly valve damper 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 of butterfly valve damper shall not be too small, generally not less than six coils; The butterfly valve manufactured in this way can ensure that the horizontal rigidity of the shock absorber is enough so that the equipment is stable and not prone to toppling, the elasticity is durable, and the lasting shock absorption capacity is guaranteed. However, the price of the butterfly valve shock absorber is often higher.
According to the weight of the water pump, the reasonable model selection is made. Generally, the compression amount of the butterfly valve after the weight of the pressure bearing water pump of the butterfly valve damper should be more than 20 mm, not more than the rated compression amount of the electric butterfly valve, so as to ensure the best vibration isolation effect of the damper. What needs to be mentioned is that at present, a popular butterfly valve shock absorber hides the butterfly valve completely inside the shell, and the state of the butterfly valve cannot be seen intuitively outside, which is somewhat incorrect!
Because, after using this kind of valve for a period of time, if the butterfly valve is seriously rusted, the manager cannot detect and replace it in time, which may lead to the terrible consequences of butterfly valve breaking, water pump sinking and pipeline breaking. Although the price of this kind of butterfly valve shock absorber is slightly lower, it should not be used as far as possible.
