X-shaped cold and hot water cross-connection block and parallel laying system of hot and cold water pipelines based on hot melt

Abstract

The invention discloses an X-shaped cold and hot water cross-connection block and a parallel laying system of water pipelines based on hot melting. The cross-connecting block is a square main body. The cold water and hot water flow channels inside the connecting block intersect at intervals. One flow channel is bent upward and the other flow channel is bent downward. The projections of the two flow channels are X-shaped cross and are not connected to each other. For the superior arc bow. The two ends of the cold water and hot water flow channels are respectively connected to the four diagonal corners of the square main body connecting block, and each side of the connecting block can derive a cold water pipe and a hot water pipe connection port. Two cold water and two hot water pipe interfaces can also be derived from the upper and lower surfaces of the connecting block of the square body. Each connection port can be connected with the PPR pipe by hot-melt fusion to form a cold water and hot water delivery pipeline that is perpendicular to each surface and can be connected in parallel. It can form a cold and hot water pipeline system in which cold water and hot water pipelines are laid and transported in parallel on the same plane and drawn out in parallel at multiple points. It has simple structure, convenient installation, firm and beautiful appearance, and increases the water delivery efficiency and stability. It is suitable for all cold and hot water pipelines. Hot water piping system. Also suitable for parallel conveying of different media.

Description

technical field [0001] The invention relates to the technical field of pipeline laying in construction engineering, in particular to a hot-melt-based X-shaped hot and cold water cross-connection block and a parallel laying system for cold and hot water pipelines. Background technique [0002] The places where human beings live and work need the supply of cold water and hot water, and the supply of water needs to be solved by the laying of water pipelines and water pipelines. The source of cold water is mainly supplied through the tap water pipe network system; hot water is usually supplied by electric water heaters, gas water heaters, and solar water heaters after heating the cold water. The temperature of the water is adapted to the requirements of use (such as people's bath water). Thus, cold water and hot water need to be simultaneously supplied to a point of use at one location or points of use at multiple different locations. At present, in the laying of cold water an...

Problems solved by technology

Even if bridge pipe fittings are used to reduce the distance between the centerlines of the two intersecting pipes, it is difficult to lay cold and hot water pipes in parallel

In addition, the small bending radius of the bridge pipe fittings and the reduction of the water passing area at the connection with the pipe will cause the loss of the water passing pressure in the pipeline, and sometimes cause the feeling that the water flow is not smooth

The actual pipeline laying effect is: the thickness of the intersection of the pipeline is large; the centerline of the intersecting cold and hot water pipelines is not on the same plane, and the laid pipeline must have an inclined angle, so that the pipe at the outlet of the pipeline terminal The centerlines of the roads are not parallel, which makes it difficult to connect external water equipment and is prone to water leakage; due to the different thickness of the laid pipelines, the aesthetics of the laid pipelines themselves are poor, and when covering, such as tiles and other coverings, the coverage will also be increased The difficulty of laying the parts affects the flatness and aesthetics of the wall and the ground
