Abstract
The utility model relates to a weldless corrugated jointing pipe, which is used on split air conditioners. The weldless corrugated jointing pipe has a corrugated pipe and a non-corrugated pipe, and is mainly characterized in that the corrugated pipe and the non-corrugated pipe or the corrugated pipe and the jointing pipe (such as a jointing pipe which is used for connecting valve doors, etc.) are the same pipe but not the pipe which is formed in the way that two pipes are welded together. The utility model is made from red copper material. Compared with the prior art (welded pipes are applied at present), the weldless corrugated jointing pipe has the advantages that the leakage phenomenon of welded part does not exist; the pressure resistant and vacuum resistant performance is good; impurities being left in the pipe during the welding process is avoided, and silver material and energy consumption during the welding process are saved. In addition, the weldless corrugated jointing pipe also has the advantages of convenient installation, beautiful appearance and long service life.
Description
The utility model relates to the corrugated connecting tube that uses on detachable air conditioner, or claims ripple to connect flexible pipe.
Detachable air conditioner is made up of the two-part that are installed in indoor and outdoor, and the refrigerant in two-part is carried by pipe, for ease of bending, therefore makes bellows at the turning of delivery pipe (copper tube).In the prior art in the joint of bellows and non-bellows or bellows and valve adapter etc. all by two pipes by welding, the major defect of its existence is: leakage phenomenon can occur at weld; The 2nd, trouble is installed, the horn mouth of weld is longer, and softness is not enough; The 3rd, leave impurity in the pipe during welding; The 4th, influence beautiful shape and working life.
The purpose of this utility model provides a kind of two ends at bellows and is extended to non-bellows or connected adapter by same pipe, rather than two pipes weld, and promptly are not bellows and non-bellows welding or bellows and are connected the nothing welding corrugated connecting tube of taking over welding.
The technological scheme that the utility model does not have the welding corrugated connecting tube is: bellows and non-bellows are arranged, and its bellows is the extension of same pipe with non-bellows or bellows with being connected adapter.
The utility model does not have the welding corrugated connecting tube, has pipe to shrink joint at the pipe end of bellows, is shaped on horn mouth at the head that shrinks joint.
The utility model does not have the welding corrugated connecting tube, and shrinking (as by stretching) at one of bellows by same pipe is non-bellows.
The utility model is the nothing welding corrugated connecting tube that is suitable for using on the detachable air conditioner, compared with the prior art, has following advantage and good effect: the one, there is not the leakage phenomenon of weld, and performances such as withstand voltage and vacuum-resistant are better than welded bellows; The 2nd, leave impurity when avoiding welding in the pipe; The 3rd, the ag material and the energy when having saved welding; The 4th, install very convenient; The 5th, beautiful shape, long service life.
Fig. 1 does not have the subjective figure of welding corrugated connecting tube;
Fig. 2 does not have welding corrugated connecting tube component diagram;
Fig. 3 has welding corrugated connecting tube component diagram;
Fig. 4 does not have another instance graph of welding corrugated connecting tube.
Below in conjunction with Fig. 1---Fig. 4 elaborates to embodiment of the present utility model.
The utility model relates to the corrugated connecting tube that uses on detachable air conditioner, make by the red copper material, after tube wall by copper pipe is processed into ripple, crooked easily, add that again the present technique characteristics are bellowss with the joint of non-bellows or bellows are the extensions of same pipe with being connected the joint of taking over, not two pipe welding, so being also referred to as does not have welding ripple connection flexible pipe.Not having a welding ripple to connect flexible pipe be bellows 1 with non-bellows 9 is that transition 10 with the root pipe is connected, generally earlier a certain section of copper pipe is processed bellows 1, is stretched as non-bellows 9 at one again, and bellows 1 is big or small consistent with the internal diameter of non-bellows 9,10 like this.Can shrink (stretchings) at an end of bellows equally and take over 2 for connecting, taking over to hold have horn mouth 3,8(such as Fig. 1, Fig. 2 and shown in Figure 4), horn mouth and nut 4,6 and plug screw 5 or one-way valve 7 match.Prior art (as shown in Figure 3), when bellows 1 is connected with non-bellows with connecting leg 14 or bellows, an end 12 of connecting leg 14 is inserted in the end 11 of bellowss 1, again by oxygen welding at joint 13 sealings, and want ag material, make in connecting leg 14 other ends horn mouth 3 '.If bellows is connected with non-bellows, just the end with non-bellows inserts in the bellows, again by welding.
The utility model does not have the welding corrugated connecting tube also can be widely used in aviation and petrochemical industry.
Claims (3)
1, a kind of nothing welding corrugated connecting tube that uses on detachable air conditioner has bellows and non-bellows, it is characterized in that bellows is the extension of same pipe with non-bellows or bellows with being connected adapter.
2, nothing welding corrugated connecting tube as claimed in claim 1 is characterized in that the pipe end of bellows 1 has pipe to shrink joint 2, is shaped on horn mouth 3,8 at the head that shrinks joint 2.
3, nothing as claimed in claim 1 welding corrugated connecting tube is characterized in that of bellows 1 is punctured into non-bellows 9,10 by same pipe.
