Seal-partition direct burial pipe fitting and direct burial pipe with direct burial pipe fittings

Abstract

The invention discloses a seal-partition direct burial pipe fitting and a direct burial pipe with the direct burial pipe fittings. The seal-partition direct burial pipe fitting comprises an inner pipe and a seal plate, wherein an inner hole of the seal plate is coaxially sealed, and is connected and fixed on the outer side surface of the inner pipe in a sleeving manner; outer protective pipes are fixedly arranged on the two sides of the seal plate in a sealing manner; and warm-keeping materials are arranged among the inner pipe, the seal plate and the outer protective pipes. Sealing effects of partition bins in the prior art are not good, underground water can enter from the damaged partition bin to the adjacent partition bin, and a warm-keeping effect of a pipe network is influenced, so that the seal-partition direct burial pipe fitting with a good partition bin sealing effect and the direct burial pipe with the direct burial pipe fittings are provided.

Description

technical field [0001] The invention relates to a thermal pipeline directly buried in the ground, in particular to a sealed partition type directly buried pipe fitting and a directly buried pipe with the directly buried pipe fitting. Background technique [0002] Directly buried thermal insulation pipes and pipe fittings are mainly used in the central heating industry. They are composed of inner pipes, polyurethane insulation layers and outer protection pipes. Their working environment is directly buried in the soil all year round. Therefore, when the steel pipe leaks or the outer protective pipe cracks, the maintenance personnel of the pipe network often cannot detect the leak point of the pipeline at the first time, which will cause the medium water in the steel pipe or the groundwater in the environment to penetrate into the insulation layer. If this situation is not dealt with in time, the high temperature and humid working environment will accelerate the aging speed of ...

Problems solved by technology

[0005] For this reason, the technical problem to be solved by the present invention is that the sealing effect of the partition warehouse in the prior art is not good, and the groundwater will still enter the adjacent partition warehouse from the damaged partition warehouse, which will affect the heat preservation effect of the pipe network, and then provide a partition Sealed partition type direct-buried pipe fittings with good sealing effect and direct-buried pipes with such direct-buried pipe fittings
