The building is made of reinforced cement and other materials. The drainage system should be arranged first in the building. The electric ball valve must be used wherever it is used. The electric ball valve shall be properly selected among the electric 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 electric ball valve need to be selected. It is quite convenient to install the electric ball valve in the basement and sewage equipment, and the operation is also quite flexible. What's more, we choose the electric ball valve in high-rise buildings, which will not damage the wall, and will not cause the wall to be ugly. In addition, we can also directly use electric ball valves in septic tanks and sewage treatment plants, because electric ball valves play a very important role in underground sewage works. It can not only resist huge impact, but also has strong liquidity and force transmission function.
When selecting the material of the electric ball valve, select the corrosion resistant material, which can effectively increase the service time of the electric ball valve and other conveying devices used in construction projects. The double flange electric ball valve is installed in the pipeline, which not only compensates for the insufficient expansion of the electric ball valve pipeline, but also is used to cause great inconvenience to the construction unit due to the stress, deformation, distortion and damage of the electric ball valve at the distribution position of the electric ball valve during the medium change of the electric ball valve, The double flange electric ball valve can expand and contract axially within a certain range to overcome the displacement, misalignment, expansion and expansion of the electric ball valve at various angles. The electric ball valve can be freely retracted in the electric 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 the electric ball valve. The double flange electric ball valve is suitable for connecting with the flange and welding with the electric ball valve at the same time. During installation, adjust the installation length between the two ends of the product and the electric ball valve or the flange, tighten the gland bolts diagonally and evenly, and then adjust the nuts, so that the electric ball valve can expand and contract freely within the expansion range, lock the expansion amount, and the electric ball valve can operate safely.
