Problems solved by technology

[0002] The current solar and air energy water pipes are easy to freeze in cold seasons. People usually use heating tape to keep warm or use antifreeze instead of water or take the method of emptying the water pipe to prevent freezing. Power consumption, the use of antifreeze will increase the cost, and the method of pipe emptying will make the emptying invalid when the pipe forms a backwater bay in the low-lying place

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. When the equipment is installed, the plastic hot-melt composite pipe of the required length is cut off, and the inner liner is gently expanded to the inner wall at the upper nozzle of the pipe to be tightly attached to it, and the upper expansion ring is pressed into the nozzle to make the inner lining The pipe and the hot melt pipe are integrated at the expansion ring, and then the upper nozzle is connected to the upper equipment through the thermal fuse. When the pipe is emptied, the water in the upper equipment is drained first, and then the air is passed through the expansion ring. The ventilation gap is input into the interlayer between the outer pipe wall and the inner liner, making it easier for the inner liner to shrink together. At the lower nozzle of the pipe, gently expand the inner liner to the inner wall to closely adhere to it, and then conn...

Abstract

A special anti-freezing plastic composite pipe is composed of a pressure-resistant plastic hot melting pipe and a non-pressure-resistant thin film lining pipe. The lining pipe is composed of an elastic thin plastic film, the lining pipe is attached to the inner wall of the plastic hot melting pipe but can be freely separated from the inner wall of the plastic hot melting pipe, the hot melting pipe is used for bearing water pressure, and the lining pipe is used for water flowing. The composite pipe not only can well convey water, but also can assist complete emptying of all pipelines.

Description

technical field [0001] The invention relates to a plastic water delivery pipe, in particular to an antifreeze plastic water delivery pipe. Background technique [0002] The current solar and air energy water pipes are easy to freeze in cold seasons. People usually use heating tape to keep warm or use antifreeze instead of water or take the method of emptying the water pipe to prevent freezing. Consumption of electric energy, the use of antifreeze will increase the cost, and the method of pipeline emptying will make the emptying invalid when the pipeline forms a backwater bay in a low-lying place. Contents of the invention [0003] The purpose of this invention is to provide a special solution to the problem of water accumulation in low-lying places after the pipeline is emptied. We design a composite hot-melt pipe. This plastic composite pipe is made of a pressure-resistant plastic main pipe and a non-pressure-resistant film lining. It is characterized in that the pressur...
