Microsoft Yahei ball valve installation instructions< br/> The ball valve is a control component in the pipeline system that can quickly cut off and connect the medium. In order to ensure the safety of people and property, the corresponding ball valve must be correctly selected, and the installation, use and maintenance must be standardized.
When installing and tightening, use a wrench on the hexagonal or octagonal part on the same side of the thread. Do not wrench the hexagonal or octagonal part on the other end of the valve to avoid deformation of the valve. PTFE raw material tape or thread must be used Sealing glue to seal.
When installing and tightening the valve, you must use a corresponding torque wrench or pipe wrench. Just screw in the effective thread length. Do not cause excessive pressure on the inner end surface, causing damage to the ball surface and leakage. To ensure the normal use of the valve, try to ensure the normal use of the valve in the pipe. Install filters at road entrances.
The handle of the ball valve is designed according to the use environment and environment of the valve and the corresponding torque. Do not use a larger force arm instead to avoid damage to the valve due to excessive operating torque. At the same time, excessive closing speed will produce water hammer that instantly doubles the pressure. effect. Frequent fluctuations in pipeline pressure or temperature will reduce its life, and corresponding preventive measures should be designed.
The valve stem sealing packing is polytetrafluoroethylene. If there is corrosion and leakage, the gland can be tightened to compensate for the packing. When replacing the packing, the medium pressure must be relieved.
