[0001] The utility model relates to the technical field of underground drainage pipe fittings, in particular to an underground drainage PVC pipe fitting. Background Art
[0002] The main component of PVC pipe fittings is polyvinyl chloride, and its heat resistance, toughness and ductility can be enhanced by adding other ingredients. PVC pipe fittings are found in various drainage places, and their better pipe bodies can better drain water into underground sewage pipes.
[0003] When PVC pipe fittings of the prior art are used for underground drainage in rural areas in remote cold regions, the PVC pipe fittings are usually wrapped with thermal insulation cotton covers and buried underground for drainage. Some debris remains in the underground PVC pipe fittings, causing water to remain in the pipe. The PVC pipe is often susceptible to low temperatures and freezes. When the PVC pipe freezes, it will affect the drainage use of rural residents. It is more laborious to dig up the soil layer to heat the PVC pipe to melt the ice. For this reason, we propose an underground drainage PVC pipe fitting. Utility Model Content

After the underground pipe of the underground drainage PVC pipe fitting freezes, hot water can be poured into the heat-introducing pipe fitting, and the hot water can be introduced into the frozen position in the underground pipe with the help of the pipe fitting structure. The frozen position in the underground pipe can be melted after being irrigated with hot water and then flow out of the underground pipe. The underground pipe of the underground drainage PVC pipe fitting can be conveniently maintained by melting ice in winter with the help of the heat-introducing pipe fitting of the utility model, which facilitates the use and maintenance of the underground drainage PVC pipe fitting in rural areas in winter and can effectively solve the problems in the background technology.

[0019] Among them, the cross-shaped groove body of the slitting groove 16 is centrally opened on the surface of the rubber disc 15, and a circular hole is expanded at the rubber disc 15 in the middle of the slitting groove 16; after the slitting groove 16 and the circular hole are opened at the middle disc body of the rubber disc 15, hot water will fall from the slitting groove 16 after flowing to the rubber disc 15, and the notch will be opened, so that the hot water can flow into the upper pipe 7.
[0020] Among them, a handle 14 is fixed to the upper cover plate of the plug cover 13, and the lower cover plug of the plug cover 13 is inserted downward into the bucket 12; the plug cover 13 can be lifted by holding the handle 14, and the lower cover plug of the plug cover 13 can be softly inserted into the bucket 12 for sealing.
[0021] Among them, the bottom mouth of the bucket 12 is vertically interconnected with the upper embedded tube 11, and the tube body of the upper embedded tube 11 is inserted into the vertical filling tube 10 and fixed by glue; hot water can flow into the bottom mouth of the bucket 12 and flow into the upper embedded tube 11, and the upper embedded tube 11 and the vertical tank tube 10 are reinforced with glue after being embedded.
