How to maintain and repair the pneumatic ball valves with different treatment methods.
The inner part of the valve is filled with inert gas, and the product produces elastic function through the piston. The product works without external power, does not lift disorderly, and can stretch freely. (The lockable balloon valve can be positioned arbitrarily) It has a wide range of uses, but the installation should pay attention to the reasonable use and installation method. Here, Shanghai Dongfeng will summarize and rectify the following installation precautions for pneumatic ball valves!
1、 Fair use and installation mode
1. The piston rod of the balloon valve must be installed in the downward position instead of upside down, so as to reduce friction and ensure good damping quality and buffer function.
2. Determining the installation position of the fulcrum is the guarantee for the accurate operation of the pneumatic ball valve. The balloon valve must be installed with an accurate method, that is, when it is closed, let it move over the central line of the structure, otherwise, the balloon valve will often automatically push the door open.
3. The balloon valve shall not be subjected to tilting force or transverse force during operation. It shall not be used as handrail.
4. In order to ensure the reliability of sealing, the piston rod surface shall not be damaged, and paint and chemicals shall be applied on the piston rod strictly. It is also not allowed to install the balloon valve at the required position before spraying and painting.
5. The balloon valve is a high-pressure product, which is strictly and randomly analyzed, baked and bumped.
6. Pneumatic ball valve Pneumatic ball valve piston rod rotates strictly to the left. If the valve direction needs to be adjusted, it can only be rolled to the right.
7. Operating ambient temperature: － 35 ℃ － ＋ 70 ℃. (. Custom made 80 ℃)
8. When installing connection points, they should roll flexibly without jamming.
9. The selected size should be reasonable, the force size should be appropriate, and the stroke size of the piston rod should have an 8mm margin.
10. Do not use pneumatic ball valve beyond the recommended safe extension height
11. In order to extend the service life of the pneumatic ball valve, please do not use the pneumatic ball valve below. low compression height
12. Do not use the pneumatic ball valve under the pressure of more than 0.7Mpa.
13. Do not use the pneumatic ball valve in a twisted state
2、 Instructions for storage, transportation and use of pneumatic ball valves
1. Transportation, loading and unloading shall be done without rough work
2. It should be stored in a dry and ventilated warehouse to avoid direct sunlight.
3. The installation position shall have enough installation space to avoid contact with oil, acid-base substances and sharp substances.
4. Avoid touching the pneumatic ball valve with sharp tools: the matching parts shall be smooth without edges and corners.
The manufacturer of pneumatic ball valve reminds that please do not inflate the components without any restrictions. Components must be limited by suspension or other suitable structures. Do not exceed the pressure recommended in the design manual. Improper use or excessive inflation will cause component damage, function damage or severe personal injury.
