The vertical distance between the vertical installation joint of the pneumatic ball valve and the ground should not be less than 0.6m; when the pneumatic ball valve is installed vertically between floors, the single linear length of the pneumatic ball valve should not be greater than 3.6m; the single floor over 3.6m should be made in more than two sections , Intermediate fixing brackets should be installed between the layers. The connection point of the pneumatic ball valve should not be in the part through the floor. When the pneumatic ball valve is installed through the floor hole, no sewage or debris should enter the inside of the busbar.
1. Pneumatic ball valve plug and feed hole (bifurcation interface) should be located in a safe, reliable and convenient position for installation and maintenance. When the pneumatic ball valve is installed vertically, the spring bracket should be installed on the pneumatic ball valve first, and then the pneumatic ball valve and the spring bracket should be fixed on the channel steel fixing frame, and the spring nut of the bracket should be locked; Loosen the nut layer by layer, so that the weight of the pneumatic ball valve is naturally carried on the spring of the bracket. After the pneumatic ball valve is connected tightly, its bending degree is not more than 1 degree. The distance between two pneumatic ball valves installed vertically adjacent to each other should not be less than 0.1m. When the linear laying length of the pneumatic ball valve exceeds 60m, an expansion (telescopic) joint should be provided.
2. After installing the plug-in box, the front and rear claw-shaped cards should be fixed on both sides of the pneumatic ball valve, and the screws should be tightened. For plug-in boxes with large switches inside, load-bearing support arms should be installed at the bottom when they are installed vertically; load-bearing hoop should be installed when they are installed horizontally. Transition connection of the pneumatic ball valve The start end of the pneumatic ball valve is connected to the terminal of the power distribution cabinet, and the transition connection should be made of tinned hard copper bar. When connecting the start end of the pneumatic ball valve to equipment with high vibration such as transformers, generator sets, etc., copper braided soft connections should be used.
3. When the copper bus bar is connected to the aluminum conductor, a copper-aluminum transition bar or a copper-aluminum transition piece should be used. The safe power transmission operator of the pneumatic ball valve must be a qualified professional electrical installer, and non-professionals must leave the viewing area. When power is supplied, the pneumatic ball valve system cannot carry any electrical load, and all the wiring devices are in a disconnected state. Maintenance of pneumatic ball valve Pneumatic ball valve is regularly inspected and repaired at least once a year during long-term operation. Check that the total load current must not exceed the design current and the rated current of the main pneumatic ball valve.
