Abstract

The invention discloses a coating and nano compound thermal-insulation tube sleeve, which comprises two half shells which can be jointed together to form a complete tube sleeve body, wherein at least one thermal-insulation layer is arranged on each of the inner walls of the two haft shells; at the vertical joint position of the two half shells, the end face of the joint position of one of the half shells is a longitudinal waterproof convex rib, the end face of the joint position of the other half shell is a longitudinal waterproof recess matched with the longitudinal waterproof convex rib, and the longitudinal waterproof convex rib and the longitudinal waterproof recess are connected in an embedding way; a fireproof coating layer is coated on each of the inner wall surfaces of the two half shells in the at least one thermal-insulation layer; and the thermal-insulation layer is a nano flexible thermal-insulation layer of which the outside is adhered to the shell by a mesh fabric. The coating and nano compound thermal-insulation tube sleeve has the characteristics that: the structure is simple; use is convenient and reliable; a certain sealing effect can be achieved; water inflow is prevented; the service life of the tube sleeve is prolonged; the thermal-insulation effect of the tube sleeve is strengthened; the use cost of the tube sleeve is reduced; daily maintenance is convenient; and the like.

Description

A kind of application and nano composite heat insulation pipe box

Technical field

What the present invention relates to is a kind of case that connecting tube carries out pipe protection and insulation usefulness outward, especially a kind of pipe box with complex heat-preservation of being exclusively used in.

Background technique

Existing connecting tube is mainly used in fluid transmission pipes such as heat distribution pipeline, oil product etc., and they are in outdoor exposed environments basically, expose to the sun and rain, and the Environmental Conditions that has is very abominable, causes easily that pipe splits, breakage, the working life of reducing pipeline; And for heat distribution pipeline, the great amount of heat that then can run off, energy loss is serious; For this reason; At present a lot of connecting tubes all can be used the pipe box case, and this pipeline case is on the outer wall of connecting tube, to coat layer protective layer at first, and this protective layer comprises having protective layer heat insulation effect, that have thermal insulation layer; But this protective layer is in case brushing just is difficult to dismounting on tube wall, even behind the mandatory dismantling also be disposable destructive the dismounting.So a kind of removable pipe box case prefabricated, that the scene of taking just can directly be installed has appearred in market now; This removable pipe box case is spliced by the two halves pipe box at least, and the needs based in the splicing are equipped with hasp or the flange edge that interconnects usefulness like the jointing positions at the two halves pipe box; The jointing positions of two halves pipe box need be used the parts that are similar to fastening piece at least; Like said hasp etc. it is interconnected, owing to after the actual splicing, exist certain splicing slit in jointing positions; These slits bring crack will for whole pipe box case, make the rainwater inside of dipping tube cover case easily easily.Therefore not only profile is not attractive in appearance for being seen in the market pipe box case, and easy deformation reduces the working life and the using effect of pipe box case, and only relies on conventional adiabator layer to be incubated, and heat preservation effect is unsatisfactory.

Summary of the invention

The objective of the invention is to overcome the deficiency that existing technology exists, and provide a kind of simple in structure, easy to use, reliable; Can play the rainproof effect of certain sealing; Prolong its working life, increase its using effect, and can also play the application and the nano composite heat insulation pipe box of fine heat insulation effect.

The objective of the invention is to accomplish through following technological scheme; It includes two half-shells that can be spliced into a complete pipe box body each other; On said two halves outer casing inner wall, be respectively arranged with one deck thermal insulation layer at least, the jointing positions up and down of described two half-shells, wherein a half-shells jointing positions end face is vertical waterproof convex tendon; Second half shell jointing positions end face is the vertical waterproof groove that cooperates with it, and both mutual chimeric connections; Be coated with on the two halves outer casing inner wall face in the described thermal insulation layer of one deck at least and be shaped on one deck fireproof paint layer.

Described thermal insulation layer is the soft thermal insulation layer of one deck nanometer, it is bonded on the shell with grid cloth in the outside of said nano thermal insulation layer.

Described two half-shells are spliced into straight length each other; Side ports at this straight length is formed with a reducing; This reducing internal face is provided with a hoop waterproof convex tendon or a groove; And being formed with the enlarging that matches with said reducing at the opposite side port, this enlarging is provided with corresponding hoop waterproof groove or convex tendon; Described thermal insulation layer is fixed on the indent shell wall that forms between at one end said reducing inboard and the said enlarging of the other end inboard.

The internal face of described two half-shells is provided with many shallow walings that are uniformly distributed with and shallow many horizontal stiffening ribs of intercross arrangement with it.

The invention belongs to a kind of improvement to existing technology, it has simple in structure, and is easy to use and reliable, can play certain sealing effect, prevents into water, prolongs its working life, increases its heat insulation effect, reduces its user cost, is convenient to characteristics such as running repairs maintenance.

Embodiment

To combine accompanying drawing that the present invention is done shown in detailed introduction: Fig. 1-4 below; It includes two half-shells 1 that can be spliced into a complete pipe box body each other the present invention, on said two half-shells, 1 inwall, is respectively arranged with one deck thermal insulation layer 2 at least, the jointing positions up and down of described two half-shells 1; Wherein a half-shells jointing positions end face is vertical waterproof convex tendon 3; Second half shell jointing positions end face is the vertical waterproof groove 4 that cooperates with it, and both mutual chimeric connections, owing to be the chimeric splicing of end face; Therefore have the rainproof effect of better seal, see shown in Figure 2; Be coated with on the two halves outer casing inner wall face in the described thermal insulation layer of one deck at least 2 and be shaped on one deck fireproof paint layer 5 and constitute composite heat-insulating layer.

Shown in Figure 4, described thermal insulation layer 2 is the soft thermal insulation layer of one deck nanometer, it is bonded on the shell 1 with grid cloth 6 in the outside of said nano thermal insulation layer.

Shown in Figure 1; Described two half-shells 1 are spliced into straight length each other; Side ports at this straight length is formed with a reducing 7, and this reducing internal face is provided with a hoop waterproof convex tendon 8 or a groove, and is formed with the enlarging 9 that matches with said reducing at the opposite side port; This enlarging is provided with corresponding hoop waterproof groove 10 or convex tendon; Said structure can form a kind of pipe structure of meeting sb. at the airport, and just at the straight tube pipe box of said same size, one section enlarging 7 of a straight tube pipe box can be matched with the reducing 5 of another root straight tube pipe box; And the groove 8 that utilizes their hoop waterproof convex tendons 6 separately to match is connected, and it plays same sealing and rainproof effect; Described thermal insulation layer 2 is fixed on the indent shell wall that forms between at one end said reducing 7 inboards and the said enlarging of the other end 9 inboards.

Shown in Figure 3, the internal face of described two half-shells 1 is provided with many shallow walings 11 that are uniformly distributed with and shallow many horizontal stiffening ribs 12 of intercross arrangement with it.Also be provided with supporting fastening screw 13 on the jointing positions madial wall shown in the figure accordingly, be convenient to two half-shells and when splicing, aim at each other.
