Hydro-electricity reform is a troublesome thing. Hydro-electricity reform refers to the renovation process of replacing all or part of the waterway and the circuit used by the original developer according to the decoration configuration, family population, living habits, and aesthetic concepts. Hydropower renovation is a crucial link in home decoration, and its quality is closely related to the safety of homeowners. Next, Xiaobian introduced the list of hydropower reform materials and acceptance techniques for hydropower reform.
Hydroelectric reform material list
1, wire category
The materials required for wires are relatively clear. They mainly include indoor house wires, single core wires, fixed telephone lines, special network cables connecting computers and wireless networks, and computer-related video and audio cables, and network crystal heads. The related auxiliary materials that need to be purchased include: waterproof tape (preferably waterproof insulation tape), wire special pipe (so that the loading wire is more neat and safe), cassette, TV distribution box, circuit breaker, elbow spring, three links, Into the box joint lock, direct head, horizontal tube.
2, waterway materials
The most common are PPR-dedicated pipes, faucets for washing machines, basin faucets for bathrooms and balconies, kitchen sinks and basins, toilets, tissue boxes, towel racks (single and double bars), bath racks, and makeup Mirrors and other related materials include deodorant floor drains, triangle valves, raw materials, back silk, thick white paint, hooks, and shifters.
3, switch type
There are many kinds of circuit switches, which can be selected according to the needs of the family. The main types are single-open single control switch, double open single control switch, three open single control switch, single open double control switch, double open double control switch, etc. Good is a double open type switch.
4, socket class
The use of sockets is inseparable from the use of indoor lines. Common sockets include two or three-hole sockets, two-hole sockets, three-hole sockets, special air-conditioning sockets (mostly 16A), and video sockets (single-link 500 Hz and double-link 500Hz two kinds), computer socket, telephone socket, audio socket, whiteboard and so on. The specific purchase quantity and specifications can be combined with the actual purchase of the home. If there is a fixed telephone placed near the outlet, there is no need to use an additional outlet.
Hydropower renovation acceptance skills
1. Hydropower acceptance steps and tools
Acceptance tools generally have supervision or construction parties to prepare, tools include pressure test pumps, flow wrenches, raw tape, plugs, jacks, pressure gauges, water tanks, connecting hoses, ammeters, etc., owners can bring their own tape measure, small notebook , small flashlights, etc., to facilitate the measurement and recording of various data in the field. Material acceptance includes pipeline inspections of waterways and circuits, whether the materials and checklists belong to the same brand and model, whether the conduits are damaged or not, and the length of use. The wiring inspection shall be based on whether the wiring of the clean water circuit complies with the specifications, including the distance, position, and direction of the water pipes, and the distribution of the wires. Pressure and electrical tests are required. Pressure test must be performed on the waterway inspection, and the circuit inspection needs to use an ammeter to test whether there are any problems in each channel. Finally, the inspection of other details, such as the condition of the drainage pipe, the drainage gradient, the position of the wire box, etc.
2, hydropower material inspection must be careful
The first step in hydropower acceptance is to inspect the material quality of wires and pipes, and secondly to look at the length of use for future settlement. First check whether the brand of the plumbing is the same as the list of decoration materials. All plumbing pipes use LPC PPR pipe. Hot and cold water pipes must have clear instructions. Cold and hot water pipes cannot be used as hot water pipes. The wire material must see if the brand of the wire is consistent with the list. In this case, the paved wires used Qingfeng brand wires. Second, the hoses used to wrap the wires are connected to PVC pipes.
3, water and electricity pipeline layout inspection
The layout of the pipeline is a question from the university. When it comes to hydropower acceptance, it is necessary to see the following points to ensure the safety of water for household use in the future. The wiring of the water pipes firstly requires “horizontal and verticalâ€, and the direction of the pipe should be reasonable. Generally, the left and right pipes and the upper and lower pipes are balanced with an angle of 90 degrees between the pipes. The wire should be a live wire. When checking, the exposed wire can be pulled back and forth. It should be able to twitch flexibly. There must be no joints or kinks in the wire line tube, and the wire should remain arcuate at the bend.
4, water pressure test and circuit test
The key steps for acceptance of hydropower are to suppress the test water and test circuit usage. These two steps are the key to checking the construction quality. When the acceptance of the waterway starts, the upper water pipe needs to be fully closed and a pressure test should be conducted. The pressure to be suppressed is generally 0.6 MPa and is closed for 24 hours. Check whether there is any leakage in the pipeline. The owner can prepare a newspaper and lay it at the joint of the water pipe. After a period of time, observe whether the newspaper has water traces caused by leakage. The circuit test first checks whether the wiring of the electrical box is reasonable, whether the main switch of the home circuit is classified clearly, and avoid using the same leakage switch in the whole house line.
Editor's summary: The list of hydropower reform materials and acceptance techniques for hydropower reform are introduced here, and we hope to help everyone. If you want to know more related information, you can pay attention to this website information.
