Description

Sponge heat-preserving hose for air conditioner

Affiliated technical field

The present invention relates to a kind of heat-preserving hose, especially a kind of sponge that utilizes that is used for Heating,Ventilating and Air Conditioning (HVAC) transporting cold wind or chilled water is realized the heat-preserving hose of insulation.

Background technique

Flexible hose is owing to need not consider pipeline rout, easy construction when stretchability and good bandability, good damping result and design, be applied to the Heating,Ventilating and Air Conditioning (HVAC) industry at home and abroad more and more, such as the thermal insulation wind pipe that is used for transporting cold wind, be used to carry the attemperater of chilled water.

The flexible heat-insulating airduct mainly is located at the ventilation air blow and return pipe end that moves towards relative complex at present, connecting central air-conditioner air main and air-conditioned room uses, what generally adopt is aluminium foil insulation vent hose, it is the aluminium foil hose of interior pipe for supporting with screw type high tension steel wire, outer surface coats insulation with glass wool, the outermost surface protection against the tide is composited by the aluminium foil fibre cloth, this structural thermal insulation flexible pipe in use exposes a lot of defectives: 1) internal layer aluminium foil hose strength is too poor, glass wool can not be wrapped, thermal insulation property is bad, causes heat to lose greatly; 2) fiber of glass wool spills easily and causes environmental pollution, and tiny fiber can cause the human body infringement after being sucked by human body; 3) outer foil is damaged easily, produces condensed water glass wool is made moist, and causes insulation failure; 4) whole typing is poor, easy deformation, and working life is short; 5) inconvenience is installed, has only site operation.

Existing water pipe heat preserving mode is normally at water pipe external application adhesive tape parcel foamed material, be used for the conveying chilled water of air-conditioning, water heater etc., the hose of hot water also is like this, because foamed material is soft excessively, intensity is low excessively, when the parcel water pipe, push because of twined by adhesive tape, the foam heat-insulation layer internal structure is damaged in various degree, thereby causes thermal insulation property to descend; Foam heat-insulation layer is easily aging, easily comes off, thereby influences water inlet thermal insulation property and working life; In addition, the installation water pipe heat-insulating layer is very inconvenient like this during construction, workload is big, and because the installment work uncontrollability, installation quality can not well be guaranteed.

Summary of the invention

The objective of the invention is to solve the problem that exists in the above-mentioned existing product, a kind of heat-preserving hose that utilizes sponge heat-insulating to have characteristics such as good heat insulating, easy for installation, survivable, long service life is provided.

Sponge heat-preserving hose for air conditioner of the present invention is to adopt following scheme to realize: comprise flexible inside and outside flexible pipe and the heat-preserving hose between inside and outside flexible pipe; Inner flexible tube is bellows or the paper tinsel layer flexible pipe that supported by screw type high tension steel wire, and outer flexible tube is a plastic flexible pipe, and heat-preserving hose is placed in the inner flexible tube outside for be foamed into flexible pipe by sponge; The mouth of pipe of heat-preserving hose is realized being connected between flexible pipe and the flexible pipe by bilateral pipe binding clasp.

Above-mentioned bellows is iron pipe, aluminum pipe or Stainless Steel Tube, has certain support strength.

Above-mentioned paper tinsel layer is aluminium foil, stainless steel foil.

Above-mentioned bilateral pipe binding clasp comprises that there is externally threaded bilateral pipe at two ends, respectively has one to enclose the rubber band of circle interpolation that clamps bar and surround at the clamping bar at the two ends of bilateral pipe, and each makes the clamping bar that rubber band is clamped with a nut screw-in two ends screw thread again.

Place a duroplasts circle in the mouth of pipe of above-mentioned inner flexible tube, make insulation pipe insert clamped clamping between duroplasts circle and rubber band behind the bilateral pipe, so just clamp better and pressed from both sides flat heat-preserving hose easily.

Nut of above-mentioned bilateral pipe binding clasp external application is fixed a suspension rod, and then realization heat-preserving hose and building is fixing, promptly fix the fixing suspension rod of a roots and tops and building on bilateral pipe binding clasp, this suspension rod bottom then is fixed on the bilateral pipe by a nut.

The invention has the beneficial effects as follows: the thermal insulation wind pipe or the attemperater that are used for central air-conditioner or domestic air conditioning, it adopts the foam sponge good heat insulating to human body safety, bilateral pipe binding clasp connects makes on-the-spot installation simple and convenient, it is that soft plastic can be crooked but be difficult for puncturing heat-preserving hose long service life of the present invention that flexible pipe bulk strength height is difficult for flattening deformation, outer surface.

Specific embodiments:

With reference to the accompanying drawings the concrete structure of this sponge heat-preserving hose for air conditioner is described in detail below.

As shown in fig. 1, it comprises flexible inner flexible tube 3, outer flexible tube 1 and the heat-preserving hose 2 between inner flexible tube 3, outer flexible tube 1, wherein inner flexible tube 3 is a bellows, and outer flexible tube 1 is a plastic flexible pipe, and heat-preserving hose 2 is placed in inner flexible tube 3 outsides for being foamed into flexible pipe by sponge.

The material of bellows is iron pipe, aluminum pipe or Stainless Steel Tube.

Inner flexible tube 3 also can be the paper tinsel layer flexible pipe that is supported by screw type high tension steel wire, and the paper tinsel layer is aluminium foil, stainless steel foil.

As shown in Figure 2, the mouth of pipe of heat-preserving hose is realized being connected between flexible pipe and the flexible pipe by bilateral pipe binding clasp, and fixes a suspension rod 8 on bilateral pipe binding clasp, to realize the fixing, very convenient firm of heat-preserving hose and building.

Shown in Fig. 2,4, bilateral pipe binding clasp comprises that there is externally threaded bilateral pipe 9 at two ends, one circle clamping bar 9a is respectively arranged at the two ends of bilateral pipe 9 and clamping rubber band 5 of circle interpolation that bar 9a surrounds, each makes with a nut 6 screw-in two ends screw threads and clamps bar 9a with rubber band 5 clampings again.

During on-the-spot the installation; in the mouth of pipe of inner flexible tube 3, place a duroplasts circle 4; heat-preserving hose inserts bilateral pipe 9 backs between duroplasts circle 4 and rubber band 5 like this; and along with the continuous clamping of clamped 9a of the screw-in of nut 6 achieves a fixed connection; because an overfill protection of inner duroplasts circle 4 can be realized heat-preserving hose ground clamping and not flat by folder well.

As shown in Figure 3, a step 9b is respectively arranged in the two ends of bilateral pipe 9, inner flexible tube 3, outer flexible tube 1, heat-preserving hose 2 and rubber band 5, the duroplasts circle 4 of forming heat-preserving hose all withstand on this step 9b after inserting, can play impermeable effect to the sponge of heat-preserving hose 2 like this, avoid insulation failure, make it can be used for attemperater.

Above-mentioned suspension rod 8 bottoms of fixing with building are fixed on the bilateral pipe 9 by a nut 7, and suspension rod 8 tops are promptly fixed with building.

The present invention is fit to attemperater, thermal insulation wind pipe and uses, the heat-preserving hose part can factory earlier with interior, in, outer three layers package,, very convenient, quick, firm during site operation as long as the mouth of pipe inserted in the bilateral pipe binding clasp clamp.
