How to judge the common specifications and models of pneumatic ball valves? What is the meaning of three eccentric?

The building is made of reinforced concrete and other materials. The drainage system should be arranged first in the building. Pneumatic ball valves must be used wherever they are used. The pneumatic ball valve shall be properly selected among the pneumatic ball valves and welded together after connection to ensure good waterproof sealing effect.
The drainage system in high-rise buildings is in a relatively hidden wall, so the model and performance of pneumatic ball valve need to be selected. It is quite convenient to install pneumatic ball valves in the basement and sewage equipment, and the operation is also quite flexible. What's more, the selection of pneumatic ball valves in high-rise buildings will not damage the walls, and will not cause the walls to be ugly. In addition, we can also directly use pneumatic ball valves in septic tanks and sewage treatment plants, because pneumatic ball valves play a very important role in underground sewage disposal projects. It can not only resist huge impact, but also has strong liquidity and force transmission function.
When selecting the material of the pneumatic ball valve, select the corrosion resistant material, which can effectively increase the service time of the pneumatic ball valve and other conveying devices used in construction projects. The American standard double flange pneumatic ball valve is installed in the pipeline, which not only compensates for the insufficient expansion and contraction of the pneumatic ball valve pipeline, but also is used to cause great inconvenience to the construction unit when the distribution position of the pneumatic ball valve begins to be stressed, deformed, distorted and damaged during the process of changing the medium of the pneumatic ball valve, The American standard double flange power transmission joint can expand and contract axially within a certain range to overcome the displacement, misalignment, expansion and expansion of pneumatic ball valves at various angles. The pneumatic ball valve can be freely retracted in the pneumatic ball valve. Once the maximum expansion and contraction amount is exceeded, it will play a limiting role. So as to ensure the safe operation of pneumatic ball valve. The American standard double flange pneumatic ball valve is suitable for welding with the pneumatic ball valve while connecting with the flange. During installation, adjust the installation length of the two ends of the product and the pneumatic ball valve or flange, tighten the gland bolts diagonally and evenly, and then adjust the nuts, so that the pneumatic ball valve can expand and contract freely within the scope of expansion and contraction, lock the expansion and contraction, and the pneumatic ball valve can operate safely.
