Description
Technical field
The utility model relates to a kind of condensation tube, particularly relates to a kind of connecting elbow being positioned at condensation tube crooked position place.
Background technique
All need in condenser to arrange condensation tube, in order to fully ensure heat exchange effect, condensation tube needs to have certain length, particularly large-scale condenser, and the length of condensation tube is longer.For realizing concentrated heat exchange, condensation tube needs to bend.Under prior art condition, when mounted the mode of long tube by bending can be bent, also can weld bend pipe at bending part by the mode of welding.The shaping condensation tube of wrap direction, operation bothers, to obtain the shape of condensation tube wayward.Prepare condensation tube by welding manner, operating speed is slow, high to welding requirements, and leaking easily appears because of corrosion in solder joint place.
Summary of the invention
For overcoming above-mentioned defect, the utility model technical issues that need to address: provide a kind of condensation tube connecting elbow, this bend pipe, as the curved section of condensation tube, is convenient to the shaping of condensation tube.
For solveing the technical problem, the technical solution of the utility model: a kind of condensation tube connecting elbow, comprise the connecting tube taken the shape of the letter U, the two end part of connecting tube are equipped with connecting structure, connecting structure comprises the coupling head of tubular, it is characterized in that, in coupling head, be provided with collar, the interior oral area of collar is provided with some oblique latches stretching to connecting tube, is provided with O-ring seals in coupling head.This connecting elbow is as a part for condensation tube, when carrying out the preparation of condensation tube, the copper tube of straight-bar type is plugged in coupling head, on collar, the outer end of latch is flexibly pushed up and is pressed on the outer circumferential face of copper tube, to realize the clamping to copper tube, prevent copper tube from throwing off mutually with connecting elbow.O-ring seals realizes coupling head and copper tube hermetic seal between the two.
In coupling head, be provided with packing ring, packing ring is between O-ring seals and collar, and O-ring seals is positioned at inside coupling head.By arranging packing ring, can prevent latch from having an impact to O-ring seals when deformation.
The truncation surface of packing ring is in " convex " font, and collar is shelved on the plush copper position of packing ring, has interval between packing ring and O-ring seals.The shape of packing ring truncation surface, is convenient to latch and has enough spaces when deformation, and is convenient to packing ring keeps stability in coupling head.
In coupling head, be provided with retainer ring, the inner of retainer ring is crimped on packing ring, and the plush copper position on packing ring is positioned at retainer ring, is crimped on the convex shoulder of side outside retainer ring in the outer port part of coupling head after deformation.Press solidly packing ring by retainer ring, structural compactness is good, is convenient to preparation.
Be provided with coaxially in retainer ring and unload circle, the outer end of unloading circle reaches the outside of retainer ring, and the outer circumferential face unloading circle inner is the butt conical surface, and this butt conical surface is for supportting the latch on collar outward; The outer circumferential face unloading circle is provided with bulge loop, and the seam on retainer ring inner peripheral surface carries out axial limiting by the clamping to bulge loop to unloading circle.Unloading circle by arranging, latch can be supportted outward, conveniently copper tube is extracted out in connecting elbow, be convenient to change copper tube or connecting elbow.
The internal diameter of described coupling head is greater than the internal diameter of connecting tube.This makes to be convenient to limit the axial position of copper tube in coupling head, is conducive to the shaping of condensation tube entirety.
Therefore, the beneficial effects of the utility model: the condensation tube entirety with this connecting elbow is split-type structural, be by the copper tube of straight-bar type and connecting elbow shaping by inserting mode.Do not need to take integrally bending to the preparation of condensation tube, or shaping, easy to process by welding manner, structure is simple.O-ring seals in coupling head effectively can ensure the sealing between connecting elbow and copper tube.Be provided with when unloading circle in coupling head, can change copper tube or connecting elbow easily.
Accompanying drawing explanation
Fig. 1 is the longitudinal sectional view of this condensation tube connecting elbow.
Fig. 2 is the amplification view at this connecting elbow first line of a couplet joint area place.
Embodiment
See in figure, the structure of the utility model condensation tube connecting elbow comprises the connecting tube 1 of U-shaped, is provided with connecting structure at the two ends place of connecting tube 1, and connecting structure comprises columnar coupling head 3.Coupling head 3 is in the end of connecting tube 1 by expanding and shaping, and the diameter of coupling head 3 is greater than the diameter of connecting tube 1.
In coupling head 3, side is provided with O-ring seals 2, and the arranged outside in O-ring seals 2 in coupling head 3 has step surface, and packing ring 6 is shelved on this step surface, and makes to have interval between packing ring 6 and O-ring seals 2.The truncation surface of packing ring 6 is in " convex " font, and the plush copper position on packing ring 6 is towards the outer port part of coupling head 3.The exterior edge face at the plush copper position of packing ring 6 is shelved with collar 7, and collar 7 is generally be made up of stainless steel, and the interior oral area of collar 7 is one-body molded some latches 8, and latch 8 is oblique stretches to connecting tube 1.
Fixing for ease of realizing packing ring 6, in coupling head 3, be provided with retainer ring 5.The inner end of retainer ring 5 is crimped on packing ring 6, and the plush copper position on packing ring 6 is positioned at retainer ring 5.The outer circumferential face of the outer side of retainer ring 5 forms convex shoulder, and the outer port part of coupling head 3 is by the interior convex shoulder be crimped on after deformation on retainer ring 5.
Be provided with actively in retainer ring 5 and unload circle 4, the outer end of unloading circle 4 reaches the outer side of retainer ring 5, and the outer circumferential face unloading circle 4 the inner is frustoconical, when unloading circle 4 towards coupling head 3 axial medial motion, the outer circumferential face unloading circle 4 the inner matches with latch 8, for supportting outer for latch 8.For positioning unloading circle 4, in order to avoid unload circle 4 to deviate from coupling head 3, one-body molded on the outer circumferential face unloading circle 4 have bulge loop 9, and retainer ring 5 inner peripheral surface is provided with seam, by the clamping of seam to bulge loop 9, and makes to unload circle 4 and can not deviate from coupling head 3 easily.
When this connecting elbow is prepared, the shaping coupling head 3 by expanding operation, then put into O-ring seals 2, packing ring 6, collar 7 successively, unload circle 4 and retainer ring 5, then carry out interior to deformation to coupling head 3 outer port part, and coupling head 3 outer port part is crimped on the convex shoulder on retainer ring 5.Finally, connecting tube 1 is made to bend to U-shaped.
When carrying out condensation tube and preparing, directly being inserted in coupling head 3 in the copper tube self-unloading circle 4 of direct rod shape, on collar 7, the outer end of latch 8 is flexibly pushed up and is pressed on the outer circumferential face of copper tube.When outwards extracting copper tube, due to the clamping effect of latch 8, copper tube can stably remain in coupling head 3, and the copper tube of many direct rod shapes and multiple connecting elbow link together and constitute curved condensation tube.
When needing to change, make to unload circle 4 towards the inner axial motion of coupling head 3, unload the inner side stay of circle 4 and open latch 8, namely can easily copper tube be extracted in coupling head 3, realize changing.
