Abstract

The utility model relates to a thermal insulation tube salver used for the middle and high temperature pipeline, the thermal insulation tube salver is opened with a fixation hole having a matched size with the pipeline, the bottom of the tube salver is provided with a bottom frame (5), the fixation hole comprises an inner layer (3), a middle layer (2) and a surface layer (1) closely cooperated from the inner to the outer, wherein the inner layer (3) is made from silicic acid aluminium fibre, the middle layer (2) is made from adiabatic thermal insulation material, the surface layer (1) is made from a steel board, a slide board (6) is soldered at the bottom of the bottom frame (5), which ensures the tube salver to expand with the pipeline and slide on a fixation board (8) along the axial direction. The tube salver has the advantages of beautiful figuration, convenient installation and flexible sliding. The heat losses of the tube salver are only about 20 percent of the general tube salver, so the tube salver also has the advantages of low heat loss. As the tube salver need not be soldered with the pipeline when being installed, the pipeline is not injured, so the service life of the pipeline is improved.

Description

A kind of insulating pipe bracket

Technical field

The utility model relates to and a kind ofly is applicable to that heating power conveyance conduit in the industries such as thermoelectricity, oil, chemical industry, chemical fibre is fixed on the conduit saddle on the support, particularly a kind of medium and high temperature pipeline insulating pipe bracket.

Background technique

The medium and high temperature pipeline conduit saddle that uses both at home and abroad mostly is T type structure at present, conduit saddle and pipeline enclosure will weld dunnage, the heat of the part on the pipeline will be directly passed to support and be caused heat loss by heat bridge and the conduit saddle that dunnage forms, and the welding when installing simultaneously causes damage to pipeline.

The model utility content

The purpose of this utility model is to provide that a kind of thermal loss is little, simple installation, compact structure, do not damage the medium and high temperature pipeline insulating pipe bracket of pipeline.

For achieving the above object, insulating pipe bracket of the present utility model has the fixed hole that matches with line size, and fixedly hole wall is divided into mesosphere and top layer from inside to outside, and the conduit saddle bottom comprises underframe, slide plate, fixed plate.Wherein the mesosphere is made of heat insulation thermal insulating material, and the top layer adopts steel plate to make, and slide plate is welded on the bottom of underframe, and conduit saddle is slided on fixed plate vertically with pipe expansion.

As a kind of improvement of the present utility model, for the ease of installing, top layer, mesosphere can be made into cooperation half and half watt shape structure up and down closely, two halves respectively have bolt hole up and down on the top layer, by bolt two halves connection up and down, firm, for the upper half part on the top layer that reduces cost can be made two band shape hoops that separate.In order to make mesosphere and tube contacts tight, increase an internal layer that adopts alumina silicate fiber felt at surface of contact, internal layer also plays the effect of shock-absorbing and insulation simultaneously.

As another kind of improvement the of the present utility model, influence conduit saddle slip flexibility in order to prevent the conduit saddle slide plate from getting rusty, slide plate adopts stainless steel to make.Adopt the polyfluortetraethylene plate thermal insulation between fixed plate and the slide plate.

The utility model is compared with existing conduit saddle, has beautiful shape, simple installation, slip flexible characteristic.Because the utility model conduit saddle is provided with thermal-protective coating, to compare with existing conduit saddle during use, the conduit saddle outside wall temperature reduces about 150 ℃～250 ℃, and thermal loss only is about 20% of a common conduit saddle, therefore also has the little characteristics of thermal loss.Owing to do not need to weld when installing, can not cause damage, so improved the working life of pipeline to pipeline with pipeline.

Fig. 2 is that the left side of the utility model insulating pipe bracket is looked.

Embodiment

Insulating pipe bracket is made with the internal layer 3 usefulness alumina silicate fiber felts that pipeline 4 closely contacts, mesosphere 2 is adopted bottom, the slide plate 6 that steel plate is made, slide plate 6 is welded on underframe 5 for heat insulation thermal insulating material, top layer 1 and can be slided at fixed plate 8 upper edge pipeline axials, influence the slip flexibility for anti-limited slip plate gets rusty, slide plate adopts stainless steel.Insulating pipe bracket adopts split watt shape structure up and down, has bolt hole on top layer 1, divides body portion by bolt connection, firm up and down.In order to reduce cost, top layer 1 upper half part is made two band shape hoops that separate, and in order to prevent to get rusty, the outer surface of conduit saddle can be coated with the last layer rust proof paint, for better thermal insulation, is lined with tetrafluoroethylene plate 7 at the surface of contact of fixed plate and slide plate.

Claims
