The pneumatic ball valve damper is an elastic element that uses the reaction force of compressed air in the pneumatic ball valve as the elastic restoring force. Today, Dongfeng Xiaobian told you about the points and maintenance of pneumatic ball valve:
Performance of pneumatic ball valve:
1。 The nonlinear performance curve can be designed into an ideal shape.
2。 Small mass, small internal friction, high frequency vibration has good vibration isolation and noise reduction ability.
3。 By adjusting the internal pressure of the pneumatic ball valve, its stiffness and bearing capacity can be adjusted.
4。 The production process is complex and the utilization rate is high. According to the working deformation mode, pneumatic ball valves are divided into three types: capsule type, membrane type and hybrid type.
Maintenance of pneumatic ball valve:
When the pneumatic ball valve is kept, if there is slight air leakage on the cover and capsule of the self sealing pneumatic ball valve, it is usually not treated, or the pneumatic ball valve is discharged and then expanded, which can generally eliminate the leakage. The pneumatic ball valve leaks repeatedly and seriously. If necessary, it should be replaced and checked. Replace the wrong part or replace the whole valve. For the pneumatic ball valve in industrial application, the contact part with the upper and lower capsules will cause wear of the relative sliding friction surface. The capsules will cause serious wear on the cord layer of the capsules, especially for the lateral swinging frame in the general direction, wearing the pneumatic ball valve and the lower edge of the contact part of the cap capsule or the test capsule. Pay attention to check whether the capsule surface allows slight scratches and wear, However, if the steel wire layer is worn, a new product should be replaced. In the process of producing pneumatic ball valves, this process is actually very complicated, but we should pay attention to that, in order to ensure its performance and aesthetic requirements, this polishing is indispensable. This is a very critical step. Today, I will talk to you about the general problems that need attention when polishing pneumatic ball valves, First of all, we know that the surface of the pneumatic ball valve produced generally may have many defects or burrs, and it is very stable in performance, such as corrosion resistance, so we need this polishing to improve the effect, followed by cleaning in the process of operation, But this method and liquid are different from our usual cleaning work. Generally, they are acid cleaning, so the danger is very high. We must pay attention to the protective measures, and there are strict rules for the thoroughness of the cleaning. Generally, not only should the cleaning be uniform, but also the surface should not have any oil residue, After polishing, we need to check the effect.
Compared with the traditional screw ball valve, the pneumatic ball valve has many advantages:
1。 The stiffness of the pneumatic ball valve varies with the load and is vertical. The height, bearing capacity and stiffness of the ball valve are widely used, which makes the ball valve device have ideal performance.
2。 According to the height control of pneumatic ball valve and the change of ball valve load, the height of high control valve is used to maintain a certain height.
3。 The pneumatic ball valve is non-linear. The performance curve can be designed as the ideal shape of axial, radial and rotary integrated isolation, and can also be transferred.
4。 By adjusting the internal pressure, the pneumatic ball valve can obtain different bearing capacity and adapt to different load requirements.
5。 High frequency vibration isolation and sound insulation performance of pneumatic ball valve. Pneumatic ball valve is composed of air and, with small internal friction. It is not because of the inherent vibration of the ball valve itself, so it can isolate high-frequency vibration. In addition, the pneumatic ball valve has no metal contact, so the sound insulation effect is very good. The pneumatic ball valve is compressed into the compressed air in the sealed container, and the role of the ball valve is reflected by the compressibility of the gas. The common pneumatic ball valve device consists of a ball valve body, an additional air chamber and a height controller.
