Abstract

The invention relates to a pipes' temperature protection device, especially, a compound insulating pipe knot which can be fast installed and dismantled. It includes two pipe knots that can be combined into a body. There is an insulating layer on the pipe knots and there is a containment vessel in outer side of insulating layer. Its characters lie in: there is a reinforce net in inner side of the insulating layer; there is a connecting fitting on two pipe knots groupware which can combine two pipe knots groupware into one body. Step-shape sealing surface is formed on portrait end face and side end face. The step surface can match with step surface of pipe knots groupware whose upside and downside is close to side face. With merits of firm structure, convenient installation and dismantlement, the device adapts to industrialized production, can reduce labor intensity and improve work efficiency. It is one of ideal attemperators used for hot working pipes' heat preservation.

Description

Combined insulation pipe covering

Technical field

The invention belongs to a kind of pipe insulation protective equipment, but particularly relates to the combined insulation pipe covering of a kind of quick mounting and dismounting.

Background technique

In the prior art, the application of thermal technology's pipeline heat-insulating technology is commonplace, its objective is in order to reduce the energy loss of line transportation thing, the efficient of pipeline transmission is provided, pipe insulation is made of thermal insulation layer and protective layer, existing heat preservation technology adopts the method for construction of layering substep, to be wrapped on the pipeline body as thermal insulating materials such as the rock wool of thermal insulation layer or glass wools earlier, again aluminium skin or iron sheet etc. are pressed into pipe shape, be wrapped in the thermal insulation layer outside, form protective layer, perhaps wiping one's face with cement material etc. forms protective layer; This technology is simple, application is general, but have that the field fabrication difficulty is big, high material consumption, inefficient problem, during site operation, environment also there is certain pollution, back dismounting difficulty, the not reproducible use of part material are installed in insulation, cause waste of material and secondary environmental pollution, and the care and maintenance inconvenience of pipeline.

Summary of the invention

The purpose of the invention be to provide a kind of simple in structure, dismounting and easy for installation, intensity is high, good heat insulating, reusable, and the long combined insulation pipe covering of life cycle.

The technical solution of the invention is such: combined insulation pipe covering comprises two pipe box assemblies; described two pipe box assemblies can be combined into one; on described pipe box assembly, be provided with thermal insulation layer; the thermal insulation layer outside is provided with containment vessel; it is characterized in that described thermal insulation layer inboard is provided with reinforcing network; be provided with link on two pipe box assemblies, this link can join two pipe box assemblies together.

The invention compared with prior art, owing to be provided with reinforcing network in the thermal insulation layer inboard, the link of quick combination or separation is set on two pipe box assemblies, longitudinal terminal surface and side direction end face at the pipe box assembly are equipped with step surface, it can match with the step surface of adjacent with the side up and down pipe box assembly, form step-like sealing surface, because the invention has sound construction, mounts and dismounts conveniently, helps industrialized production, can alleviate operation labor intensity and improve advantages such as work efficiency rate, it is one of desirable thermal insulation apparatus that is used for thermal technology's pipe insulation.

Below in conjunction with accompanying drawing and fact Example, the invention is described further:

Embodiment

At Fig. 1, among Fig. 2 and Fig. 3, the described combined insulation pipe covering 1 of the invention comprises two

pipe box assemblies

2,4, described two

pipe box assemblies

2,4 can be combined into one, on described pipe box assembly, be provided with thermal insulation layer 7, thermal insulation layer 7 outsides are provided with containment vessel 9, the surface of described thermal insulation layer 7 is provided with reinforcing network 10, at two

pipe box assemblies

2,4 are provided with link 3, this link 3 can be with two

pipe box assemblies

2,4 join together, longitudinal edge and transverse edge in described

pipe box assembly

2 and 4 are step surface, the step surface of described two

pipe box assemblies

2 and 4 longitudinal edge can fit, and forms step-like sealing surface 6, to reach the effect of sealing; Be provided with caltrop 5 in thermal insulation layer 7, the two ends of this caltrop combine with reinforcing network 10 and containment vessel 9 respectively, to strengthen reinforcing network 10, thermal insulation layer 7 and containment vessel 9 threes' combination stability, also can adopt the high temperature binder to cohere between thermal insulation layer 7 and containment vessel 9; Described containment vessel 9 adopts fire-retardant composite fiberglass material to make; also available high strength plastics or iron sheet or materials such as corrosion resistant plate or aluminium skin are made; described thermal insulation layer 7 is made of thermal insulating material 8; described thermal insulating material 8 selects for use aluminium silicate wool or materials such as rock wool, glass wool to make, and described reinforcing network 10 adopts steel wire or glass fibre network cloth or thin-sheet metal orifice plate to make.

Described combined insulation pipe covering 1 its profile of the invention is " garden is tubular ", " elbow-shaped ", " threeway shape " and shapes such as " four-way shapes ", to adapt to the needs of actual use; The use of the invention is very convenient, only needs the pipe box body is enclosed within on thermal technology's pipeline, and with link amalgamation pipe box body together being linked into an integrated entity gets final product.
