The electric ball valve cannot be installed without the function of the fixing bracket. The electric ball valve cannot be installed without the function of the fixed support. The success of the installation of the fixed support is directly related to the normal operation of the expansion joint. During the operation of the equipment, the electric ball valve can relieve the thrust of the blind plate during the operation of the pipeline. However, at the pump outlet and at the pipe turning angle The sliding pipeline connection of infinite buttress and directional limit buttress support shall adopt force transfer joint and limit force transfer joint to avoid the thrust concentrated at the pipe corner or the near end of the pump, causing impact damage to the equipment.
There are strict regulations for installing the electric ball valve: 1. Pay attention to the setting and stress of the fixed support during installation, and the expansion end of the expansion device shall not be pulled out due to the cracking of the fixed support when pressing. 2. The installation must be designed by the design department, otherwise the pipeline is prone to problems.
3. Pay attention to the setting distance of the guide bracket. The first guide bracket should be installed at a distance of 4D (4 times) from the pneumatic valve, and the second guide bracket should be installed at a distance of 14D from the pneumatic valve. Three points can be set arbitrarily. Because the power transmission joint can transmit the thrust of the blind plate when starting the pump to all parts of the pump and pipeline through the power transmission bolt (i.e. full thread bolt), the electric ball valve, power transmission joint, expansion joint (expansion joint) and valve joint, clamp flexible joint (flexible clamp joint is referred to as clamp joint for short) and quick joint all play a common role in pipeline connection, It plays the role of expansion and displacement compensation for pipeline operation. In fact, in the use of various pipelines, electric ball valves are used to protect pipelines to a certain extent, especially to facilitate the installation and maintenance of pipelines.
