Description

Technical Field

[0001] The invention relates to the field of pipeline insulation, and in particular to a pipeline insulation device. Background Art

[0002] The existing technology of pipe insulation uses the method of wrapping insulation cotton and protective layer on the pipe surface to achieve the insulation effect. This insulation method has the following disadvantages:

[0003] 1. The joints of the pipe protective layer are prone to "bulging", and pipe fittings often have water and air ingress;

[0004] 2. The connection strength of the pipeline protective layer is not enough, and it is easy to crack when it expands and contracts;

[0005] 3. The insulation cotton collapses due to gravity and cannot meet the insulation requirements. Summary of the invention

[0006] The purpose of the present invention is to provide a pipe insulation device with waterproof support to solve the problems of water ingress, air ingress, insufficient connection force, collapse, low installation accuracy, etc. during the insulation process of traditional pipes.

[0007] In order to solve the above technical problems, the purpose of the present invention is achieved through the following technical solutions:

[0008] The thermal insulation cotton is fixedly wrapped on the outside of the pipeline, and the pipeline thermal insulation device is connected to the connection between the thermal insulation cotton segments, and together with the thermal insulation cotton, it constitutes the external thermal insulation system of the pipeline; the pipeline thermal insulation device is composed of an upper waterproof support, a lower waterproof support, a windproof sealing strip, an outer protective layer of the pipeline, a metal binding belt, an outer protective layer of the waterproof support and an internal support;

[0009] An upper water guide groove is arranged in the middle part of the upper waterproof support, which can guide and discharge a small amount of seepage water. Grooves that can be buckled and positioned for internal supports are arranged on both sides of the upper water guide groove. The internal supports make the upper waterproof support and the pipeline bear forces on each other to prevent the pipeline insulation device from collapsing due to gravity problems. Positioning holes that can be buckled and positioned for the lower waterproof support are arranged on both sides of the groove; a lower water guide groove that can correspond to the upper water guide groove is arranged in the middle part of the lower waterproof support, which can guide and discharge a small amount of seepage water. Convex grooves that can be buckled and positioned for the groove are arranged on both sides of the lower water guide groove. The convex grooves are fixedly connected to the grooves through the positioning holes, and the installation efficiency is improved by structural connection; the relationship between the upper waterproof support and the lower waterproof support is that the upper covers the lower, so as to avoid water seepage at the overlap;

[0010] The pipeline outer protective layer is fixedly arranged on the outer layer of the thermal insulation cotton, and the waterproof support outer protective layer is fixedly arranged on the outer layer of the pipeline outer protective layer; the upper waterproof support and the pipeline are mutually stressed by the metal binding belt arranged on the outer layer of the waterproof support outer protective layer, so as to prevent the thermal insulation cotton from collapsing. During installation, this is the stress point of the metal binding belt, so it also plays a role in improving the strength of the parts.

[0011] The back of the upper water guide trough is provided with a raised limiting strip which can increase the structural strength and position the outer protective layer of the pipeline.

[0012] The outer protective layer of the pipeline is provided with a waterproof groove, which is arranged in the lower water guide groove and on both sides of the raised limit strip. During installation, margins are left on both sides of the waterproof groove, which can eliminate the translation amount of the pipeline insulation device during thermal expansion and contraction. Its function is similar to that of the upper water guide groove, which can become the first barrier for waterproofing, and water can be discharged through the leakage hole arranged at the bottom of the waterproof support outer protective layer.

[0013] The windproof sealing strip is directly bonded to the groove and the convex groove, and the outer layer is covered with a pipe outer protective layer and a waterproof support outer protective layer in sequence, and is tied and fixed with a metal binding belt. In the installed state, the sealing meets the GB / T7106-2019 standard, thereby achieving a windproof function.

[0014] The two sides of the waterproof support outer protective layer are provided with raised limit points that can meet the national standard for pipeline insulation and limit the installation of metal binding belts, and the bottom is provided with leakage holes that can discharge a small amount of water that has penetrated into the pipeline insulation device in time. The leakage holes simultaneously meet the drainage requirements of the upper water guide groove, the lower water guide groove and the waterproof groove.

[0015] The beneficial effects of the present invention are:

[0016] The pipe insulation device described in the present invention can be used in conjunction with the insulation cotton of traditional pipe insulation and the outer protective layer of the pipe, so that the pipe can achieve the effects of waterproof, windproof, translatable, and anti-collapse during the insulation process. The unique structural design of the upper waterproof support and the lower waterproof support can not only ensure the strength during installation, but also provide a positioning function for the installation of other parts, thereby improving the installation accuracy and service life of the entire pipe insulation.
