Problems solved by technology
[0004] The existing installation methods of plastic water pipes are all on-site fusion welding. Due to the large amount of dust and sand on the installation site and the large difference in the proficiency of the installation workers in welding technology, it is difficult to guarantee the quality of fusion welding. If the heating time is too long and the temperature is too high, there will be welding shrinkage rings in the pipe at the welding place. Severe shrinkage rings will even block the pipeline. The welding shrinkage ring is easy to hide dirt and breed algae and bacteria, which is an important reason why the tap water or drinking water reaching the end of the hygienic waterworks is unqualified

Embodiment 1
[0023] Embodiment 1: As shown in Figure 1, the two joints respectively adopt the inner wire interface and the welding joint, and are welded together by an inner wire elbow 2, a straight pipe section 1 and a welding elbow 3, and there is no Obvious fusion welding shrinkage ring, wire plug 5 is housed in the inner wire interface, and plastic cover 4 is covered on the interface of fusion welding elbow.
Embodiment 2
[0024] Embodiment 2: As shown in Figure 2, the two joints respectively adopt an outer wire interface and a welding joint, and are welded together by an outer wire elbow 6, a straight pipe section 1 and a welding elbow 3, and there is no Obvious fusion welding shrinkage ring, the interface of the outer wire is covered with a stuffy cover 7, and the interface of the fusion welding elbow is covered with a plastic cover 4.
Embodiment 3
[0025] Embodiment 3: As shown in Figure 3, both joints adopt outer wire interfaces, which are welded together by two outer wire elbows 6 and a straight pipe section 1. There is no obvious fusion welding shrinkage ring in the pipe, and the outer wire interfaces Loam cake has stuffy cover 7 and is equipped with outer silk decorative cover.

The invention relates to a design and installation method of cold and hot water supply lines used in kitchens and washrooms, which comprises the following steps: when building a brick wall or pouring a concrete wall, a die plate is used for reserving a groove of a pre-buried water pipe assembly on the wall; a water main is laid and fixed along the wall edge, the ground is poured, and the ground accessing to the groove is not poured at the time; after the solidification of the pouring, an external interface at the upper end of the pre-buried water pipe assembly is calibrated, positioned, initially fixed, then treated with fusion welding and communicated with the underground main; and after passing the press test, the ground around the interface is back poured, and the pre-buried water pipe assembly is concealed. The pre-buried water pipe assembly comprises a straight pipe section and two interfaces arranged at the two ends of the straight pipe section, wherein, the two interfaces can adopt interfaces with internal thread or joints with external thread and are correspondingly provided with pipe plugs or blank caps, and one of the two interfaces can also adopt a fusion welding interface. The method is convenient for decoration, and avoids damages to the wall when in decoration and unnecessary waste.
Description
technical field [0001] The invention relates to a design and installation method of cold and hot water supply pipelines for kitchens and toilets and a pre-embedded water pipe assembly. Background technique [0002] The water supply pipelines of kitchens and bathrooms in existing commercial houses are generally surface-mounted. Surface-mounted water pipes not only affect the decoration of kitchens and bathrooms, but also affect the installation of their facilities. The water pipes were removed, and the hidden pipes were re-grooved on the wall. Some decorators broke the steel bars and damaged the wire casings and wires when they grooved. The above-mentioned common phenomenon is a great waste of limited resources and labor, and it violates the basic national policy of establishing a conservation-oriented society. [0003] Although there are continuous demands for fine decoration of kitchens and bathrooms in commercial housing, the existing water supply design and installation ...
