Shanghai Dongfeng Electric Butterfly Valve Manufacturing Co., Ltd., located in Shanghai Baoshan Industrial Park, 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 electric butterfly valves in China. It is mainly engaged in the research and production of butterfly valve electric butterfly valve, damping electric butterfly valve, air conditioning electric butterfly valve, electric butterfly valve, hanging butterfly valve electric butterfly valve, 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 electric butterfly valve of the butterfly valve shall be more than four times of its zero point under the rated load; The electric butterfly valve of the butterfly valve shall have a certain extra stroke, at least equal to 50% of the rated static deflection; The coil number of electric butterfly valve of butterfly valve 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 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, the reasonable model selection is made. Generally, the compression capacity of the butterfly valve after the weight of the electric butterfly valve 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. What needs to be mentioned is that at present there is a popular electric butterfly valve, which completely hides the butterfly valve inside the shell, and cannot directly see the status of the butterfly valve 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 electric butterfly valve is slightly lower, try not to use it.
