Background
The indoor water supply system of the building in China mainly adopts PPR pipes which are connected in series in a hot melting connection mode to form a dendritic water supply structure, the water supply system needs more water supply accessories, the quality of a connecting point adopting the hot melting connection is difficult to check, and the problems of uneven water distribution and large hidden danger of water leakage are easily caused.
In order to solve the problems, indoor water supply systems which supply water in parallel branches are gradually adopted in the market. The water supply system with parallel branches is connected to a central water distributor via a pipeline and distributes the water quantity uniformly to the individual water consumption points via the central water distributor. Compared with the traditional series connection dendritic water supply mode, the water supply system has the advantages of few connection points, small hidden water leakage danger, stable water pressure, uniform water flow and the like.
Due to the parallel branched indoor water supply system, a central water separator needs to be installed in the pipeline. At present, central water distributors adopted in the market are mostly copper water distributors, stainless steel water distributors, copper-plastic water distributors and the like. When the metal material is adopted as the water separator, the problem of high heat loss is easily caused due to the high heat conduction coefficient of the metal material, and the energy-saving effect is poor. And secondly, because the main bodies and the water diversion ports of the copper water segregator and the stainless steel water segregator are formed by secondary processing, the problems of cracking and water leakage of connection points and the like are easily caused by a water hammer effect in a water supply system in the using process. Thirdly, the water separator is connected with a pipeline by threads in the process of connection, and is sealed by a matched rubber ring, so that the rubber ring is easy to lose or leak to cause water leakage in the installation process; after the rubber ring is used for a period of time, the sealing performance of the rubber ring is gradually reduced due to the increase of the service life, and the hidden danger of water leakage exists.
