Home decoration lecture: The history of the most complete family of water and electricity installation knowledge decoration friends must see
Hydropower is the source of survival for modern people. Therefore, architects must install hydropower when they are building houses. Therefore, water and electricity decoration is very important for the entire home improvement. Household hydropower installation is a complex and crucial project. During the decoration process, it will be very inconvenient in the future. Before the owners of the households install water and electricity in the home, they must learn more about the installation knowledge, and then perform the installation operation according to the hydropower installation specifications. This will not only enable better installation, but also can effectively save expenses. Then, what are the steps and specifications for household water installation ? If you have this need, you may wish to follow me to learn about it! Home water installation knowledge First, the transformation of houses, first of all according to the installation of the design drawings on the part of the transformation of the house, such as the removal of certain walls, the modification of certain parts. Second, the pipe is grooved. The groove of the pipe includes two parts. One is the groove of the water pipe and the other is the slotting of the telecommunication line. The owner is best able to personally look at the construction quality during construction. Generally, the horizontal and vertical lines must be played before the trenching. The construction should be carried out according to the line. During the construction, it must be checked whether or not to follow the hydropower diagram. If there is any change, it must be changed. To indicate. Third, the water pipeline installation, the water pipe material is generally PPR pipe, aluminum plastic pipe, especially PPR pipe majority, in this one, mainly pay attention to the placement of the faucet, this piece of the owner must personally to supervise and observe, so as to ensure Meet functional utility. Fourth, the wire wiring: Now the more common wire on the market is more than 2.5-6 square meters of copper wire, in particular, here we must pay attention to, to strong and weak, switches, air conditioning sockets and electrical outlets to separate lines, and Note that the bottom of the switch socket assembly must be horizontal and vertical, so that the rear panel installation will be more flat. Here we must pay particular attention to the switch sockets of the kitchen, because the function of the kitchen is relatively strong, and it needs to be arranged and installed according to the use function. Fifth, water pipeline inspection: After the construction is completed, water pipeline inspection is indispensable, so that it can eliminate hidden water safety problems. The test method usually used is pressure test, that is, all the mouths are gambling and death. Use a pressure gauge to test the water. Check all pipe fittings after pressure. Sixth, waterproof, waterproof pipe must pay attention to the problem, after the installation of the pipeline, can be mixed with cement sand seal all the wet area of ​​the slot, necessary to do half-wall and full wall. Home Hydropower Installation Specification 1. Before the construction, there must be electrical (strong, weak), water supply and drainage design and construction drawings. 2. It is forbidden to lay the conductor directly in the wall, floor, under the floor or ceiling without any protection. 3, different voltages, different loops, different signal lines are strictly prohibited to wear in the same threading tube. 4, the installation of lamps should be done after the paint is completed. Installing lamps on brick-concrete structures, using wooden wedges, applying hooks, bolts, or expansion bolts, etc. is strictly prohibited. There should be no less than two bolts (or screws) for the fixture. Luminaires must not be installed on combustible components. 5. The switch of the lamp and electrical equipment must be installed on the "phase line" (ie, the control phase line), otherwise, the switch off, the light off and the electrical equipment is still energized, and it is easy to cause electric shock. 6. There are two protection methods for the power system: ground protection and zero protection. At present, China generally adopts the ground protection method. Note that in the same system, it is forbidden to adopt two protection methods at the same time, otherwise it will cause a safety accident. 7. It is forbidden to use a mobile switch on the bedside. If the fixture is a screw base, the center tongue of the screw base should be connected to the control phase. 8. The interface of each line should be smooth and the connection between the plates should be firm. The power inlet box interface box should be protected by a protective ring (lock nut). 9, in order to update and maintain the wire in the future, buried in the wall, underground or ceiling shed pipe, the elbow bend at the turn (ie cold bend radius) should be 5 to 10 times the diameter of the threaded pipe. 10. It is forbidden to connect the wire in the threading pipe. That is, if the length of the wire is not long enough, the joint of the wire cannot be in the threading pipe. Generally, it should be connected in the junction boxes such as switches, sockets and lamp holders. 11, threading pipe should choose a certain size (thickness), not only to enable the conductor to wear, but also to leave enough open space, so that the heat generated by the wire when passing a large current can be dissipated. The ratio of the cross-sectional area of ​​the general conductor to the cross-sectional area of ​​the conduit is 1/3 to 1/2. It is forbidden for the wire to block the conduit. 12, the water supply pipe can be PP-R pipe, brass and so on. 13, the dark grid water supply pipeline must be strictly checked whether all connected parts are tightly installed, firm, to the right, and then do the hydrostatic test, test the water for a period of time before buried. 14. The drainage pipeline should have a certain slope, and the socket is tightly connected to ensure no leakage. The spacing between the brackets and elevators for the fixed pipes is reasonable and firm. 15. The installation position of sanitary appliances should be accurate, and the support and bracket should be flat and firm. The floor drain should be installed at the lowest point of the ground and be 5mm recessed. The connection between the toilet and the floor or the nozzle is sealed with sludge or silicone, and cement should not be used. The cement will expand and cause cracks in the bottom of the toilet. 16. The hot water faucet in the hot and cold taps should be installed on the left side. The electric water heater should have a grounding protection device. When it is used for the first time, the air in the gall bladder should be removed. After filling the water, it can be started by electricity.
