Problems solved by technology

[0004] In the process of laying the heating pipeline, due to the needs of construction, the heating pipeline needs to be laid in bends, and when the heating air passes through the above-mentioned bends, it is very easy to cause the inertia of the above-mentioned bends. The outer wall is scoured, causing excessive wear of the outer wall, causing premature failure of the heating pipe, causing a large amount of hot steam and hot water to leak out. Since most of the heating pipes are buried underground, the repair difficulty and cost are relatively high, and once it occurs Large-scale leakage accidents of hot steam and hot water are likely to affect the surrounding environment and even cause casualties

Embodiment 1

[0038] see Figure 1-5 and Figure 8 , a pre-embedded pipe for a heating pipe network with a curved protection structure, comprising a metal heating pipe 1, the outer side of the metal heating pipe 1 is fixedly connected with an insulating layer 2 that matches itself, and the metal heating pipe 1 is fixed on the outside. A buffer groove 3 is excavated. The buffer groove 3 is located on the outer wall of the bend of the metal heating pipe 1. The notch of the buffer groove 3 is fixedly connected with a buffer rubber pad 4 that matches itself. A plurality of filling balls are placed in the buffer groove 3. 5. The protective grid clusters 6 are fixedly connected to the plurality of filling balls 5. The filling balls 5 include elastic rubber balls 501. Prefabricated holes 502 are drilled on the elastic rubber balls 501. The arc length of the prefabricated holes 502 does not exceed the length of the elastic rubber balls 501. A quarter, the prefabricated hole 502 is located at the e...

Abstract

The invention discloses a pre-embedded pipe for a heating pipe network with a curved protection structure, belonging to the field of pre-embedded pipes for heating, and a pre-embedded pipe for a heating pipe network with a curved protection structure. In the area where the buffer groove is located, there are buffer rubber pads, filling balls and protective grid clusters to form a flexible part. When the surface of the buffer groove is washed by hot steam, the common elasticity of the buffer groove, buffer rubber pads, filling balls and protective grid clusters can be passed through the buffer groove. Deformation to reduce the scouring force of the hot steam on the surface of the buffer tank, reduce the wear degree of the buffer tank, make the buffer tank less likely to form cracks, not easily cause the failure of the metal heating pipe and the buffer tank, and not easily affect the normal use of the metal heating pipe. It is possible to reduce the excessive erosion of the buried heating pipes at the bends, not easily cause the early failure of the heating pipes, not easily cause a large amount of hot steam and hot water to leak out, and reduce the cost of daily maintenance.

Description

technical field [0001] The invention relates to the field of pre-embedded pipes for heating, in particular to a pre-embedded pipe for heating pipe networks with a curved protection structure. Background technique [0002] In high temperature areas, after winter comes, the temperature usually drops below minus ten degrees Celsius, and it is difficult for the human body to live normally at such a low temperature for a long time. Therefore, heating devices such as "kang" have appeared in the northeast region. Usually it is a family unit. The energy utilization rate and thermal insulation effect of such heating devices generally depend on the construction level at that time. At the same time, the single-family construction design also makes the energy utilization efficiency low from a macro point of view. [0003] The urban central heating pipe network is a pipeline system that transports and distributes the heating medium from the urban central heating source to the heat users....
