Hot melting based X-type cold and hot water cross connecting block and cold and hot water pipe parallel laying system

Abstract

The invention discloses a hot melting based X-type cold and hot water cross connecting block and a water pipe parallel laying system. The cross connecting block is a square main body. A cold water flow channel and a hot water flow channel are spaced and crossed in the connecting block, one flow channel curves upwards, and the other flow channel curves downwards. Projections of the two flow channels are crossed in an X shape and do not communicate with each other. The cross section of each flow channel is in a major arc arch shape. The two ends of the cold water flow channel and the two ends ofthe hot water flow channel communicate with four opposite angles of the square main body of the connecting block. One cold water pipe connector and one hot water pipe connector can be derived from each side face of the connecting block. Two cold water pipe connectors and two hot water pipe connectors can be derived from each of the upper and lower surfaces of the square main body of the connecting block. All the connectors can be connected with PPR pipes in a hot melting mode to form cold water and hot water delivery pipes perpendicular to the faces and capable of being connected in parallel.The multi-point parallel derivative cold and hot water pipe system provided with the cold water and hot water pipes laid in the same plane for delivery can be formed. The hot melting based X-type cold and hot water cross connecting block is simple in structure, convenient to install, firm and attractive in appearance, improves the water delivery efficiency and stability and is suitable for all cold and hot water pipe systems and also suitable for delivering different mediums.

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 h
