Abstract
The utility model discloses a corrugated shock absorbing pipe, which comprises a corrugated pipe. A weaving pipe is wrapped on the outer periphery of the corrugated pipe, pipe joints are connected to two ends of the corrugated pipe, connecting pipes are arranged among the corrugated pipe and the pipe joints, and the weaving pipe is connected to the outer peripheries of the connecting pipes in a pressing manner. The corrugated shock absorbing pipe is simple in welding connection although increasing working procedures by sequentially connecting the weaving pipe, the corrugated pipe and the pipe joints to the inside and the outside of the walls of the connecting pipes one by one, is reliable in connection relationship, can realize automatic welding, improves air tightness and safety, and prolongs service life.
Description
Technical field
The utility model relates to the chiller plant connecting tube, relates in particular to a kind of ripple shock-absorbing pipe.
Background technique
Existing ripple shock-absorbing pipe generally is made up of four parts such as metal bellows 1, braided metal silk screen 2, copper connecting tube 3, overcoats 4, after these four parts are connected together, two ends directly adopt brazing that these four parts are linked together, though assembling is simple, but the difficulty of brazing is bigger, and can't adopt the automatic welding of mechanization, reject rate is higher.The ripple shock-absorbing pipe external leakage hidden danger that adopts this technology to make is more.Owing to the rosin joint of braided metal silk screen, under the effect of ripple shock-absorbing pipe internal pressure, the braided metal silk screen is very easily deviate from from weld, causes unsafe accident during use, also greatly reduces working life simultaneously.
China's utility model patent patent No. 200920045798.6 discloses a kind of band sheath bellows, this band sheath bellows comprises the bellows main body and is enclosed within the outer sheath of bellows main body, described sheath has braiding structure, and the maximum outside diameter of its internal diameter and bellows main body matches.What this kind bellows was mainly considered is the protective action of woven tube, and under the effect to pressure, the problem that comes off of woven tube and the technology that is welded to connect are not each other improved and this do not proposed any technology enlightenment yet.
Summary of the invention
The utility model provides that a kind of sound construction, tightness and Security are good, the ripple shock-absorbing pipe of long service life.
A kind of ripple shock-absorbing pipe comprises that periphery is enclosed with the bellows of woven tube, and the bellows two ends are connected with pipe joint, are provided with connecting tube between described bellows and the pipe joint, and the connecting tube periphery is crimped with woven tube.By connecting woven tube, bellows, pipe joint three inside and outside the connecting tube tube wall one by one, though increasing, operation is welded to connect simply, annexation is reliable, can realize the automation welding, improves tightness and Security, increases the service life.
Described connecting tube inner tubal wall connects bellows and pipe joint.Corrugated tube end be provided with a straight length be connected the pipe inner tubal wall both can automation withhold connection, the reliability connecting tube inner tubal wall welded bellows and the pipe joint that connect for increasing.Described connecting tube inner tubal wall two ends are provided with indent annulus be connected bellows and pipe joint outer wall.The indent circle ring inner wall that connects bellows as preferred connecting tube is provided with the indent wire loop, and wire loop adopts soldering to be connected with bellows, comprises silver brazing and copper brazing, leaks to eliminate welding.Connecting tube adopts argon arc welding to be connected with bellows, to enlarge using scope and occasion.Connecting tube adopts brazing to be connected with pipe joint, connects so that install.
Described connecting tube outer tube wall circumference is provided with the indent annulus that holds the woven tube end, the woven tube end places the snap ring that is cooperated by indent annulus periphery in the indent annulus, engagement connection guarantees that woven tube can not deviate from from indent annulus position in use, avoids bellows directly to be subjected to the damage of inner axial tube pressure.
Ripple shock-absorbing pipe of the present utility model is by connecting in the middle of the connecting tube, make the connection between bellows, woven tube and the pipe joint turn to split from one, welding turns to easily from difficulty, and the reliability of finished product, Security just can improve greatly, and this has also just improved working life greatly.

Embodiment
Shown in Fig. 2,3, the utility model ripple shock-absorbing pipe comprises that periphery is enclosed with the bellows 6 of woven tube 7, and bellows 6 two ends are connected with pipe joint 10, are provided with connecting tube 9 between described bellows 6 and the pipe joint 10, and connecting tube 9 peripheries are connected with woven tube 7.It is simple to make that by connecting tube 9 crimping woven tube 7, bellows 6, pipe joint 10 threes the integral installation of ripple shock-absorbing pipe connects, and airtight performance is improved.Woven tube 7, bellows 6, pipe joint 10, connecting tube 9 generally all adopt the metallic material manufacturing, are preferably stainless steel and copper material.
Connecting tube 9 inner tubal walls connect bellows 6 and pipe joint 10.Be provided with indent annulus be connected bellows 6 and pipe joint 10 outer walls as preferential connecting tube 9 inner tubal wall two ends.Be provided with indent wire loop 12 for increasing welding fastness and airtight performance at the indent circle ring inner wall that connecting tube 9 connects bellows 6, this place adopts argon arc welding to connect connecting tube 9 and bellows 6.
Connecting tube 9 outer tube wall circumference are provided with the indent annulus 13 that holds woven tube 7 ends.Indent annulus 13 peripheries are combined with snap ring 8.Snap ring 8 engaging woven tube 7 are fixed in the indent annulus 13, in use are difficult for deviating from owing to woven tube 7 is subjected to the control of snap ring 8 engaging power, and then protect inner bellows 6, increase the service life.
