Requirements of electric butterfly valve for butterfly valve selection:
1. First, the radius of the butterfly valve should 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;
2. 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.
Selection of electric butterfly valve for water pump butterfly valve:
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.
The electric butterfly valve is mainly used for anti vibration of pipelines and equipment in nuclear power plants, thermal power plants, chemical plants, steel plants, etc. It is often used to control the vibration of pipeline system caused by fluid vibration excitation (such as fluid pulsation, two-phase flow, high-speed flow, wind vibration, etc.). The electric butterfly valve of the butterfly valve can effectively control the vibration and swing of various frequencies, but it limits the normal thermal displacement of the pipeline to a certain extent. The additional force generated by the electric butterfly valve of the butterfly valve on the pipeline shall be fully considered in the design.
The electric butterfly valve of the butterfly valve is composed of the butterfly valve and the shell. For the most important butterfly valve component of the electric butterfly valve of the butterfly valve, how to select a suitable butterfly valve is crucial. The suitability of the butterfly valve directly determines the quality of the electric butterfly valve of the butterfly valve.
The biggest feature of the electric butterfly valve of the damping butterfly valve is that the fracture will never occur during the transportation and operation of the electric butterfly valve of the damping butterfly valve, which can increase the service life of the electric butterfly valve. Moreover, this electric butterfly valve can bear a large weight, and users can choose different damping butterfly valves according to their different needs.
This electric butterfly valve has low frequency but excellent vibration isolation effect. It is compact in structure and not very large in size and shape. 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.
