Description

Anti-stepping stainless steel thermal insulating pipe sheath

Technical field

The utility model relates to a kind of stainless steel thermal insulating pipe sheath, belong to the pipe insulation device.

Background technique

In the prior art, for the mode of pipe insulation mainly is at the coated outside of pipeline or direct one or more layers adiabator layer of application, it normally adopts on-the-spot installation mode to realize, in case in the pipeline coated outside or directly be coated with and load onto adiabator layer, when needs overhaul of the equipments or other need be removed or remove, so just be difficult to they be removed or remove, and in case necessity work through removing or removing, the a lot of dust of these material production, can not use by secondary, cause very big economic waste, and thermal insulation property is had a greatly reduced quality, the labor intensity of installation is big, and efficient is low.Commonly used is a kind of assembling type pipe insulation device in the market, it is to make the insulation external member in advance, the employing two halves composite structure that has, the employing block structure that has, during installation, as long as a plurality of external members are assembled into pipe box mutually and pipeline are wrapped up in it, can reach good heat insulation effect, but enhancing along with people's environmental consciousness, it is found that the insulation external member shell that uses glass fibre reinforced plastic material to make, the influence that can't bear high temperature for a long time, its working life is shortened in accelerated ageing easily.In some special occasions, in nuclear power engineering, the high clean free from dust of fitness for purpose requires long service life in addition, and maintenance easily can not repeat repeatedly to recycle, and satisfies the long-term purpose of using.Though some occasion also has use stainless steel material manufacturing pipe box shell, employed stainless steel sheet is thinner, and bearing capacity is not enough, easy deformation, thus influence thermal insulation property and working life.

The model utility purpose

The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of simple in structure, and easy to use and reliable, installation is simple, the efficient height, and structural strength is good, the stainless steel thermal insulating jacket of good heat insulating.

The purpose of this utility model is finished by following technical solution, and it mainly is made up of the two halves external member, and described external member is semi-cylindrical shaped, and inside and outside wall constitutes by corrosion resistant plate, is equipped with stiffener liner and thermal insulating material inside and outside this between the stainless steel flaggy.

Described outer wall is made by the figured stainless steel plate that can get anti-skidding effect, and described stiffener liner is that crisscross stiffener constitutes, and it is the thermal insulating material of nano composite that while and stiffener liner place the thermal insulation layer between the inside and outside stainless steel lining simultaneously.

Described semi-cylindrical shaped external member interior sidewall surface is provided with radial elastic saw tooth belt liner, this liner dentation end face bends, with radially become less than 90 degree or with the axial angle that becomes greater than 0 degree.

Described external member two ends respectively are provided with into end face sun interface and cloudy interface, and described two end interfaces are mutually the end face interface.

The utility model is a kind of improvement to prior art, and it adopts stainless steel material to make the internal and external layer of pipe box, is lined with stiffener in it, to keep the structural strength of pipe box, have simple in structure, easy to use and reliable, installation is simple, efficient is high, and structural strength is good, characteristics such as good heat insulating.

Description of drawings

Fig. 1 is the structural representation of half pipe box described in the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is done detailed introduction: shown in Figure 1, the utility model mainly is made up of two halves external member 1, and described external member 1 is semi-cylindrical shaped, and two halves are combined and just are combined into a cylindrical shape, in pipeline is wrapped in.Described external member 1 inwall corrosion resistant plate is made, and outer wall is made by the figured stainless steel plate, can get anti-skidding effect after the moulding; Inside and outside this, be equipped with stiffener liner 3 and thermal insulation layer 4 between the stainless steel flaggy.

Stiffener liner 3 shown in the figure is that crisscross stiffener constitutes, and it is the thermal insulating material of the nano composite of routine that stiffener liner 3 places the thermal insulation layer 4 between the inside and outside stainless steel lining simultaneously, also available other the common careful water type of no fiber thermal insulating material, and described thermal insulating material can be two-layer or more than, increasing its heat insulation effect, and described stiffener liner 3 can obviously increase the strength and stiffness of stainless steel internal and external layer.

Described semi-cylindrical shaped external member 1 interior sidewall surface of the utility model (pipeline is wrapped in an interior side) is provided with radial elastic saw tooth belt liner 5, these liner 5 dentation end face bends, with radially become less than 90 degree or with the axial angle that becomes greater than 0 degree, to form its certain elasticity, and make external member become point to contact with its interior pipeline that is wrapped, avoid heat radiation thereby this structure that better heat insulation effect is arranged.

External member 1 described in the utility model is a section identical shaped and prefabricated component structure, and described external member 1 two ends respectively are provided with into end face sun interface 6 and cloudy interface 7, and described two end interfaces are mutually the end face interface.Described semi-cylindrical shaped external member 1 outer side surface is provided with fastener member 8, is used for carrying out fixedly connected with after the splicing of two halves external member with fastener member.And said structure is after carrying out two halves splicings with fastener member 8, more successively mutually before and after mutual grafting by described positive interface 6 and cloudy interface 7, be assembled into the heat-insulating cover of a Len req.
