The most important part of the ball valve damper is the ball valve. The proper ball valve with good quality will have a vibration damping effect, which will be flexible and durable, and have a long service life. If the ball valve is not properly installed, the whole ball valve damper will be scrapped. What is a good way to purchase ball valves?
Firstly, the ball valve shall meet the following conditions: the radius of the ball valve shall 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; 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, and the elasticity is durable to ensure the lasting shock absorption capacity. However, the price of this ball valve pneumatic butterfly valve is often higher.
Reasonable selection shall be made according to the weight of the equipment. Generally, the compression capacity of the ball valve behind the pressure bearing equipment of the ball valve damper shall be greater than 20mm, not more than the rated compression capacity of the pneumatic butterfly valve, so as to ensure the best vibration isolation effect of the damper. What needs to be mentioned is that a ball valve damper is popular in the market at present, which completely hides the ball valve inside the shell, so the state of the ball valve cannot be seen intuitively outside, which is incorrect!
After a period of time, if the ball valve is seriously rusted and the manager cannot detect and replace it in time, the ball valve may be broken, until the pump sinks and the pipeline is pulled off. Although the price of the ball valve damper is slightly lower, it should not be used as far as possible.
The pneumatic butterfly valve of ball valve has a 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.
Ball valves and pneumatic butterfly valves have strong adaptability to work. They can work normally even at minus 40 degrees or minus 110 degrees. This is the working state that ordinary pneumatic 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.
Ball valve pneumatic butterfly valve is mainly used for vibration isolation of various high-frequency changing mechanical equipment such as fans, air conditioning boxes, air conditioning units, generator sets, air compressors, water pumps, cooling towers, etc.
The use of pneumatic butterfly valve has a good effect. The hardness can be controlled by adjusting the formula, which can meet the requirements for stiffness. Many people say that the use of pneumatic butterfly valve has no effect. What is the matter? Let's take a look.
