Requirements for ball valve selection of pneumatic butterfly valve:
1. First, the radius of the ball valve should be four times greater than the zero point of its height under the rated load; The ball valve shall have a certain additional stroke, at least equal to 50% of the rated static deflection;
2. The number of ball valve coils shall not be too small, generally not less than six; The ball 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 ball valve shock absorber is often higher.
Selection of pneumatic butterfly valve for pump ball valve:
According to the weight of the water pump, the reasonable model selection is made. Generally, the compression of the ball valve of the ball valve damper after the weight of the pressure bearing water pump should be more than 20 mm, not more than the rated compression of the pneumatic butterfly valve, so as to ensure the best vibration isolation effect of the damper.
Ball valve pneumatic 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 ball valve damper 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 ball valve damper on the pipeline shall be fully considered in the design.
Ball valve pneumatic butterfly valve is composed of ball valve and shell. For the most important ball valve assembly of ball valve pneumatic butterfly valve, it is very important to select the appropriate ball valve. The suitability of the ball valve directly determines the quality of the ball valve pneumatic butterfly valve.
The biggest feature of the damper ball valve damper is that the fracture will never occur during the transportation and operation of the damper ball valve damper, which can increase the service life of the damper. Moreover, this pneumatic butterfly valve can bear a large weight, and users can choose different damping ball valve dampers according to their different needs.
This pneumatic butterfly valve has low frequency but excellent vibration isolation effect, compact structure and small size. 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.
