The PPR check valve is an important component in plumbing applications, typically used to prevent backflow of water or fluid in a piping system. The valve is designed to allow water or fluid to flow in only one direction, and to close off the flow in the opposite direction.
The function of the PPR check valve is to ensure that water or fluid flows in the right direction, preventing the risk of contamination, damage to pumps or other equipment, or even the reversal of flow that could cause a system to fail. In many cases, these valves are used to prevent backflow or siphoning of water or other fluids, which could cause contamination of the water supply or other issues.
How to correctly install the PPR pipe is the key to ensure the smooth operation of the pipeline system, and the hot melt method is described in detail below:
1. When hot melting the ppr water pipe, keep your hands stable. You need to heat the ppr pipe to a certain time before you can take the ppr pipe out of the mold and then insert it quickly.
2. Before use, it is necessary to ensure that the incision of the pipe is smooth, there is no burr problem, and the welding part between the pipe and the pipe fittings should be cleaned to avoid dust.
3. Next to choose the matching heating head, the heating device to reach 250~260 degrees, with a marker on the pipe above the depth of welding.
4. In the specified time for heating, the pipe and pipe fittings in a vertical way to promote, to reach more than 5 seconds, the whole process can not be too strong, otherwise there will be bending phenomenon.
hot melt water pipe welding precautions:
1. When heating with the hot melt machine, its temperature can reach about 260 degrees, so we must wear protective gloves when operating, to do a good job of safety protection.
2. After the end of heating to use a special bracket for cooling, to prevent fire phenomenon, but also put the heating plate in a safe position, to prevent contact, to avoid the phenomenon of scalding.
3. When welding, you need to turn on the hot melt machine, when the temperature reaches 260 degrees, its indicator light will turn green, in this case can be welded.
4. Before welding should also consider the welding environment, such as the temperature can not be lower than 5 ° C, if the temperature is relatively low in winter, the heating time should also be appropriately extended.
5. The welded PPR pipeline must be tested for water tightness to check whether there is a place where the welding is not in place to ensure the long-term safe use of the PPR pipe.
