Abstract
The utility model relates to a quickly-fitted composite heat-insulation case for the pipelines of heat engineering, which is characterized in that two semi-cylindrical heat-insulation shells are fixedly arranged in an outer protective casing with a laterally opened opening to form a structure capable of opening and closing. Overlapping edges are arranged at the laterally opened opening of the protective casing, and pressure-sensitive adhesive tapes are also attached at the laterally opened opening for the connection of the opening of the casing. One end of the protective casing is provided with a flaring for the butt-joint of the heat-insulation case. The butt-joint surfaces and both ends of the two heat-insulation shells are respectively provided with a concave convex tabling structure and a butt-joint structure with conical surfaces in order to improve the sealing performance of the heat-insulation case. The heat-insulation case having a good integral heat-insulation effect is convenient to realize the standard production and carry out the construction of pipelines, and is favorable for reducing the engineering cost.
Description
The utility model relates to the thermal insulation apparatus that is used for thermal technology's pipeline, but is a kind of composite material lagging of quick mounting.
The insulation of pipeline, the particularly insulation of thermal technology's pipeline directly relate to the heat-energy losses and the efficiency of transmission of line transportation medium.For reducing thermal loss, improve efficiency of transmission, generally take the material that coated thermal conductivity is low outside delivery pipe to do thermal insulation layer, in the hope of reducing fed sheet of a media and extraneous exchange.Traditional thermal insulation layer is based on inorganic material, for example vermiculite, expanded perlite, asbestos etc., and these materials are generally powder shape, fibrous, directly use relatively difficulty, need make watt, use behind the cover, felt.Because the influence of the mechanical strength of these materials and method of construction etc., its working life, heat insulation effect are all undesirable.In recent years ask because the development of chemical industry, a kind ofly do thermal insulation layer by foaming polyurethane resin, external application is progressively promoted the use of with the thermal insulation pipe of glass fibre reinforced plastics protecting jacket.This heat preserving method is that the thermal insulation layer of conveyance conduit, external protection are directly made in factory, only need connect and partial insulation during installation.The advantage of this method is: good heat insulating, outer jointing jacket intensity height, attractive and durable can improve speed of application in plant produced.Its shortcoming is: 1, connect the naked pipe that must reserve certain-length at pipe end for guaranteeing, nozzle stub and bend pipe also can only use naked pipe, and the scene of wanting, these positions is incubated, and its site operation difficulty is bigger, also very easily are stranded construction and are not good at causing thermal loss.2, the pipeline after thermal insulation layer lays in factory, volume is bigger, and thermal insulation layer is also relative rapid wear, increased the difficulty of transportation, lifting.
The purpose of this utility model is at the problems referred to above, and provide a kind of high insulating effect, but the composite material lagging of quick mounting, this Pipeline thermal insulating sleeve had both had the advantage of glass fibre reinforced plastics sheath foaming polyurethane resin thermal insulation pipe, simultaneously again in transportation, construction be better than existing heat preserving method on working life.
For achieving the above object, the technical solution of the utility model is: a kind of quick-mounting complex heat-preservation cover with inner thermal insulating layer and outer jointing jacket is provided, and the internal layer of this lagging is the heat-preservating shell of two semicircle tubulars, is fixed in the outer jointing jacket of lateral openings; The lateral openings place of its protecting jacket is provided with overlap edge, and this overlap edge inboard is installed with pressure sensitive tape: the end at protecting jacket is provided with the enlarging of joining, and the enlarging built-in is equipped with pressure-sensitive adhesive layer.
The technical solution of the utility model also comprises: be respectively arranged with concavo-convex chimeric sealing configuration on two involutory surfaces of the heat-preservating shell of two semicircle tubulars; An end face of the thermal insulation layer that is made of heat-preservating shell is provided with conical interface, and another end face is provided with circular cone hole shape interface; Inboard at protecting jacket is provided with arc groove with the place of contact mutually of the cylindric heat-preservating shell of two halves.
The utility model compared with prior art has following advantage:
1, forms the composite structure lagging by involutory heat-preservating shell that sealing is set and plastic protective sleeve, its integral heat insulation effect and be better than prior art working life.
2, can all realize batch production production (comprising standard elbow, threeway).The user only need be by drawing purchasing standard lagging.
3,, only need improve construction speed during pipeline construction by hot insulated line normal construction not owing to can adopt standard piece to assemble fast.
4, the damage thermal insulation layer of needn't worrying when pipeline transport, lifting, thus convenient transportation, simplify mounting process.
5, can adopt multiple thermal insulating material, applicability is wide, and overall cost is low.
Fig. 1 is the radial section figure of this quick-mounting complex heat-preservation cover;
Fig. 2 is the axial section and the connection schematic representation of quick-mounting complex heat-preservation cover:
Fig. 3 is the I partial enlarged drawing of Fig. 1;
Fig. 4 is the II partial enlarged drawing of Fig. 1.
The utility model is described in further detail below in conjunction with drawings and Examples.
Provide as accompanying drawing, just expect to be bonded in the semicircle tubular heat-preservating shell 1 make on the protecting jacket 2 of the lateral openings of making by semi-hard plastics by insulation for two, form compound cover body structure to be opened/closed.Have section on the conjunction plane of the cylindric heat-preservating shell of two halves and be trapezoidal concavo-convex embedded structure 3, to guarantee the sealability after the closure.Arc groove 9 is arranged on the protecting jacket 2, make two and half tubular heat-preservating shells 1 it be the axle freely openable.Protecting jacket 2 has overlap edge 4 at opening; this overlap edge inboard has pressure sensitive tape 10, after lagging is contained on the pipeline, the protective film on the pressure sensitive tape is torn; just firmly compress and form solid and reliable butt joint at opening, so far one section quick-mounting complex heat-preservation cover installs.Conical interface 7 and the circular cone hole shape interface 8 that matches, the butt joint of end face and reliable sealing when being used to install are set respectively at the two ends of the lagging of being made up of semicircle tubular shell 1.One end of protecting jacket 2 has the enlarging 5 that is used to join, and there is pressure-sensitive adhesive layer 6 enlarging 5 inboards, during installation, install the last period earlier, tear the protective film on the pressure-sensitive adhesive layer off, next section is installed again and presses to cement fixed interface.The heat preservation construction of whole pipeline is finished in order repetitive operation successively.
The heat-preservating shell 1 of this lagging can require to adopt materials such as polyurethane foam plastics, ureaformaldehyde foamed plastics, water glass ten vermiculites to make according to serviceability temperature.Protecting jacket 2 adopts semi-hard ageing-resistant plastic board, and the outer surface color can be selected by the line transportation medium.Half tubular heat-preservating shell 1 can adopt glue or integral foam to connect by production technology with protecting jacket 2.
When pipe diameter＞350 millimeter, the protecting jacket of this lagging can adopt upper and lower overlap edge connecting structure, its objective is to stack transportation.
