The suspended 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 the pneumatic butterfly valve of the ball valve on the pipeline shall be fully considered in the design.
The suspended ball valve damper is a vibration control device that is sensitive to displacement. The suspended ball valve damper is mainly applicable to 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.). 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 manufacturer of suspended 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 the suspended ball valve damper on the pipeline shall be fully considered in the design.
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 suspended ball valve shock absorber is often higher.
Model selection: the compression capacity of the ball valve of the general suspended ball valve damper after the pressure pump weight is more than 20 mm, 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 at present, there is a popular hanging ball valve damper on the market, which completely hides the ball valve inside the shell, and the state of the ball valve cannot be seen intuitively outside, which is somewhat incorrect! Because after using this kind of valve for a period of time, if there is serious corrosion of the ball valve, the manager cannot detect and replace it in time, which may lead to the terrible consequences of breaking the ball valve, sinking the pump, and pulling off the pipeline. Although the price of this suspended ball valve damper is slightly lower, it should not be used as far as possible.
