Firstly, the butterfly valve shall meet the following conditions: 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.
Reasonable selection shall be made according to the weight of the equipment. Generally, the compression capacity of the butterfly valve behind the pressure bearing equipment of the electric butterfly valve of the butterfly valve shall be more than 20mm, 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, a popular electric butterfly valve of butterfly valve is on the market. It completely hides the butterfly valve inside the shell, and the state of the butterfly valve cannot be seen intuitively outside, which is incorrect!
After a period of time, if the butterfly valve is seriously rusted and the manager cannot detect and replace it in time, the butterfly valve may be broken, until the pump sinks and the pipeline is pulled off. Although the price of this kind of electric butterfly valve is slightly lower, try not to use it.
The electric butterfly valve of the butterfly valve has a very low frequency. It is used for high-frequency vibration equipment. The vibration isolation effect is very good, and the structure is compact, but the size and shape are not very large. This makes it more convenient to install and reliable and safe to use. Although the shape is relatively small, the application life is not short.
The electric butterfly valve of butterfly valve has a strong adaptability to work. It can work normally even at minus 40 degrees or minus 110 degrees. This is the working state that ordinary electric butterfly valves cannot reach. Whether it is active vibration isolation, passive vibration isolation or shock vibration, it has a very significant effect and can effectively block the sound transmission of solids. It has achieved ideal results in isolation of vibration, reduction of noise, remediation of vibration pollution and environmental protection.
The butterfly valve electric butterfly valve is mainly used for vibration isolation of fans, air conditioning boxes, air conditioning units, generator sets, air compressors, water pumps, cooling towers and other high-frequency changing mechanical equipment.
