Description

A kind of HVAC pipe of antirust insulation

Technical field

This utility model is related to HVAC Manifold technology field, specially a kind of HVAC pipe of antirust insulation.

Background technology

HVAC pipe is mainly used in cleaning system and sends airduct, central air-conditioning ventilation duct, industrial supply and exhaust ventilation duct, environmental protection system back to System suction airduct, mining drainage gas pipe, the occasion such as mining gummed cloth air duct, it is seen that the scope of application of HVAC pipe widely, The simple structure of traditional HVAC pipe, on the one hand during long range propagation, not only heat insulation effect is poor, and in transmitting procedure Heat loss is serious, on the other hand when HVAC pipe conveys hot water or steam, as HVAC pipe is common steel tube or galvanized pipe, With being continuously increased for use time, inner-walls of duct easily produces rust, then As time goes on cause the corruption of HVAC pipe Erosion ruptures, and disassembly and separation renewal cost is very high, for the problems referred to above, special to propose a kind of HVAC of antirust insulation Pipe.

Utility model content

The purpose of this utility model is to provide a kind of HVAC pipe of antirust insulation, to solve to propose in above-mentioned background technology Problem.

For achieving the above object, this utility model provides following technical scheme：A kind of HVAC pipe of antirust insulation, including it is outer Polyethylene tube, the outer Interior Wall of Polythene Pipe are cased with two ends between outer tube, and outer Interior Wall of Polythene Pipe and outer tube outer wall and are equipped with Hot melt adhesive layer, the outer tube wall are cased with heat-insulation layer, and the heat-insulation layer inwall is cased with inner tube, and said inner tube inwall is cased with cohesion second Alkene pipe, interior polyethylene tube one end internal diameter are equal to interior polyethylene tube other end external diameter.

Preferably, the outer tube and inner tube are stainless steel tube, compo pipe or iron pipe etc..

Preferably, one end of the interior polyethylene tube is equipped with external screw thread, and the interior polyethylene tube other end is provided with interior spiral shell Stricture of vagina.

Preferably, the heat-insulation layer is set to foam glass layer.

Preferably, the interior Interior Wall of Polythene Pipe is provided with semicircle groove.

Compared with prior art, the beneficial effects of the utility model are：A kind of HVAC pipe of antirust insulation, simple structure, Design is ingenious, easy to use, carries out antirust treatment to outer tube and inner tube by the setting of interior polyethylene tube and outer polyethylene tube, prevents Only inner and outer tubes are got rusty under long-time use, solve inner and outer tubes corrosion in the case of long-time use Problem；By filling heat insulating wall between inner and outer tubes, the insulation effect of hot water and steam during long range propagation is served, Solve the problems, such as because of long range propagation hot water and steam heat loss.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of this utility model protection.

Fig. 1-3 are referred to, this utility model provides a kind of technical scheme：A kind of HVAC pipe of antirust insulation, including it is outer poly- Ethylene tube 1,1 inwall of outer polyethylene tube are cased with two ends between outer tube 2, and 2 outer wall of 1 inwall of outer polyethylene tube and outer tube and are all provided with There is hot melt adhesive layer 3, outer polyethylene tube 1 prevents 2 long-time of outer tube from getting rusty using lower contact with extraneous humid air or ground, heat Melt layer 3 facilitates quick connection of this utility model in work progress, 3 inwall of the outer tube to be cased with heat-insulation layer 4, heat-insulation layer 4 Playing prevents hot water and steam from serious heat loss is produced in long distance delivery, and 4 inwall of the heat-insulation layer is cased with inner tube 5, described 5 inwall of inner tube is cased with cohesion ethylene tube 6, and interior polyethylene tube 6 prevents inner tube 5 from producing rust in long-time conveying hot water and steam And then corrode, 6 one end internal diameter of the interior polyethylene tube is equal to 6 other end external diameter of interior polyethylene tube, facilitates two interior polyethylene tubes Connection, while improve inner tube 5 antirust ability.

Specifically, the outer tube 2 and inner tube 5 are stainless steel tube, compo pipe or iron pipe etc., product price it is cheap and The ability of opposing destruction is strong.

Specifically, one end of the interior polyethylene tube 6 is equipped with external screw thread 7, and 6 other end of interior polyethylene tube is provided with Female thread 8, facilitates the dismounting and replacing between two interior polyethylene tubes 6.

Specifically, the heat-insulation layer 4 is set to foam glass layer, and foam glass layer has good heat insulating, sound absorption, prevents The characteristics of tide, fire prevention, high-strength light.
