Xiao Bian believes that mastering a little, home installation hydropower installation knowledge, is very necessary, because this can be a small problem in the home water and electricity, do not panic, you can also solve it, then, the decoration home Xiaobian, Let me introduce to the pro, what are the home installation hydropower installation knowledge , as well as the hydropower installation skills, I hope that the introduction of Xiaobian can make friends no longer a rookie in the installation of water and electricity.
First, the introduction of home installation hydropower installation knowledge
1. The water pipe is slotted, and the water pipe is slotted: the construction method, the first line, and then the slot. Pipeline grooving must be parallel and vertical as required (if there is a hydraulic construction drawing, the construction drawing is better). The lines that must be paralleled are always controlled at 60-90 cm high (from the ground), and the pipes with faucets must be vertical. The depth is controlled at 4 cm. After the trunking is opened, the person in charge of the construction will record the size and position of the slotted pipe. It is convenient to know the position of the pipeline when the sanitary ware is installed.
2, water pipeline installation, water pipeline installation: material requirements, PPR pipe, aluminum plastic pipe. Most users bought aluminum-plastic pipes three years ago, and there are more users of PPR pipes in the past two years. The pipeline is divided into cold water pipes and hot water pipes. Hidden pipes are used to prevent the use of galvanized iron pipes. First, through the hydropower installation construction drawings, the construction personnel and the owner discuss the water location and use functions. Arrange the hydropower master to discharge all the faucets and water locations. If there is a construction drawing, it can be arranged according to the construction drawing. If the construction road water function is not in place for a long time, communicate with the owner to increase the water use function.
3, wire circuit wiring, wire circuit wiring: material requirements, 2.5-6 square meters copper core wire, 16mm or more wire pipe. Wiring requirements: Most electrician masters do not consider the connection between strong and weak electricity, switches, air-conditioning outlets and electrical outlets in circuit wiring. Therefore, slotting also saves a lot of processes.
4, the requirements of strong electricity and weak electricity wiring at the bottom limit of 30 cm, air-conditioning outlets dedicated to more than 6 square meters of wire grouping, electrical outlets dedicated 4 square meters group, switch 2.5 square meters or more dedicated grouping. The air conditioning line group is more than 2 meters away from the ground. The electrical line group ground wiring, switch and lighting line group wall top line. The bottom of the switch socket must be installed horizontally and vertically so that the rear panel installation will be flatter. The switch sockets of the kitchen shall be arranged and installed according to the function of the design of the kitchen cabinet. After all the electric lines are arranged, the person in charge of the construction keeps track of the layout and discharge size of the line, so as to facilitate the installation of various home accessories in the later stage.
Second, the introduction of hydropower installation skills
1. There must be electrical (strong electricity, weak electricity), water supply and drainage design and construction drawings before construction.
2, the threading pipe should choose a certain size (thickness), not only to make the wire wear, but also to leave enough space, so that the heat generated by the wire when passing a large current can be dissipated. Generally, the ratio of the cross-sectional area of ​​the wire to the cross-sectional area of ​​the threaded pipe is 1/3 to 1/. It is forbidden to block the threading pipe by wires.
3. Different voltages, different circuits, and different signal lines are strictly prohibited from being worn in the same threading pipe.
4. It is strictly forbidden to lay the wires directly in the wall, in the floor, under the floor or on the ceiling without any protection.
The above is a small series for everyone to introduce, home installation hydropower installation knowledge and hydropower installation skills are different, I hope that through the introduction of Xiaobian, parents can master some home improvement hydropower installation knowledge, if you want to understand, more home improvement Information, please continue to pay attention to, decoration home network.
