Abstract
The utility model discloses a hose joint fixed connection structure, which comprises an external connecting pipe, a middle connecting pipe, a protective pipe, a corrugated pipe, and a wire mesh pipe. The middle connecting pipe has a straight through structure, steps are arranged on the outer wall thereof, and the part, on which the leftward large end surface is fixedly connected with the corrugated pipe and the wire mesh pipe, is arranged inside the protective pipe. The protective pipe is fixedly connected with the rightward large end surface of the middle connecting pipe, and the left end part of the middle connecting pipe is in socket joint with the thin-walled external connecting pipe and is fixedly connected therewith. The external connecting pipe is made of red copper, and other components are made of stainless steel. The hose joint fixed connection structure adopts the middle connecting pipe as a transition socket joint structure, and all joints are connected by molten welding, thereby resulting in reliable connection, high strength and tight sealing. Most of all, the heat from the subsequent welding of the external connecting pipe can not influence the quality of the previous molten welded joint. The hose joint fixed connection structure is suitable for air conditioners and refrigerating devices with different specifications.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly a kind of hose coupling.
Background technique
During the compressor operation of large power air-conditioned device and refrigeration plant, certainly lead to vibration, in order to reduce the side effect of vibration, with pipeline that the compressor inlet/outlet is connected between set up flexible pipe with vibration absorption ability.Normal conditions bottom hose section material is a stainless steel, and socket is the red copper material, and poor because of red copper and stainless weldability, prior art adopts method for welding to realize effectively connecting.Soldering is the thawless a kind of welding of a kind of mother metal, and this welded joint also easily at the later process hose coupling when copper pipe is done to dissolve welding with connection, melts preposition soldered joint because of being heated and to cause hose coupling seal failure, reduction in strength except that intensity is low.
The model utility content
The utility model is primarily aimed at the deficiencies in the prior art, provides a kind of merogenesis structure, connection reliably, not to be subjected to adjacent welding heat affected hose coupling fixed connection structure.
The utility model is achieved through the following technical solutions technical goal.
The utility model hose coupling fixed connection structure, it comprises externally connected pipe, middle adapter, pillar, bellows and wire mesh tube.Taking in described is the straight-through tube structure, and outer tube wall is provided with step, and the position of fixedlying connected with wire mesh tube towards left large end face and bellows places in the pillar.Improvements are: described pillar is fixedlyed connected towards right large end face with middle adapter, also fixedlys connected with the externally connected pipe socket of thin-walled in middle adapter right part.
Be both the pillar and the middle adapter of stainless steel in the said structure, adopt the argon shield welding easily to achieve a fixed connection.Externally connected pipe is the thin-walled copper tube, and middle adapter right-hand member liner constitutes the lining docking structure in externally connected pipe, adopts the argon shield welding to achieve a fixed connection with this understanding.The middle right-hand member mouth of pipe of taking over is that internal taper hole can reduce liquid resistance and flow noise.
The utility model compared with prior art, jointing all adopts molten solder to connect in the structure, that joint connects is reliable, intensity is high, sealing is tight, the thermal destruction that the most important thing is the follow-up welding of externally connected pipe not preposition molten solder joint quality.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
In order to further specify technical solutions of the utility model, do the detail explanation below with reference to the accompanying drawings and in conjunction with the embodiments.
Hose coupling fixed connection structure shown in the drawings, it comprises externally connected pipe 1, middle adapter 2, pillar 3, bellows 4 and wire mesh tube 5.Taking over 2 in described is the straight-through tube structure, and outer wall is provided with step, and the position of fixedlying connected with wire mesh tube 5 towards left large end face and bellows 4 places in the pillar 3.Pillar 3 is fixedlyed connected towards right large end face with middle adapter 2, and the middle adapter 2 right-hand member mouths of pipe are internal taper hole, significantly reduces liquid resistance and flow noise.Also fixedly connected with the externally connected pipe 1 left end socket of thin-walled in middle 2 right parts of taking over.Externally connected pipe 1 is the red copper material in the present embodiment, and all the other members are stainless steel.At first, routinely flexible pipe 4, wire mesh tube 5 are fixedlyed connected with middle adapter left side.Then, pillar 3 and middle adapter 2 are adopted the argon shield welding towards right large end face.At last, with the externally connected pipe and the middle adapter 2 right-hand member sockets of red copper material, externally connected pipe 1 is implemented the argon shield welding under middle adapter 2 right-hand member liners.Argon shield welding is a kind of molten solder, strength of welded joint height, good sealing effect, most important be externally connected pipe 1 follow-up welding thermal destruction not preposition molten solder joint quality.
