Abstract
The utility model discloses a needle valve connection structure in an air conditioner pipe assembly, comprising a needle valve and a bottom pipe connected with the needle valve, wherein the pipe wall of the bottom pipe is provided with a T drawhole, the needle valve is welded to the T drawhole by a transition pipe, and the end part of the transition pipe, which is welded with the T drawhole, is provided with a convex part of which the outer diameter is more than the inner diameter of the T drawhole. The needle valve connection structure in an air conditioner pipe assembly of the utility model is characterized in that the pipe wall of the bottom pipe is provided with the T drawhole, so that the external diameter of the convex part of the transition pipe, which is welded with the T drawhole, is more than the inner diameter of the T drawhole, the welding leakage can be reduced, and meanwhile, the refrigerant inflow amount in the pipeline can be improved.
Description
Technical field
The utility model relates to a kind of needle-valve syndeton, relates in particular to the needle-valve syndeton in a kind of air-conditioning organ pipe assembly.
Background technology
In air-conditioning organ pipe assembly needle-valve erection welding process, as shown in Figure 1, existing connected mode is with bottom tube 2 punchings, needle-valve 1 is directly inserted in the bottom tube 2 weld again.
In the operation of air conditioner process, this kind connected mode has certain obstruction to produce to the refrigerant that flows through, and simultaneously, this kind connected mode is revealed easily, thereby to the complete machine performance and the parameter generating influence of air-conditioning, to user's using and keep in repair and cause very big inconvenience from now on.
The utility model content
The utility model provides the needle-valve syndeton in a kind of air-conditioning organ pipe assembly at the drawback of prior art.
Needle-valve syndeton in the air-conditioning organ pipe assembly described in the utility model, the bottom tube that comprises needle-valve and connection thereof, the tube wall of described bottom tube is offered T and is pulled out the hole, described needle-valve is welded in T by a transition conduit and pulls out the hole, this transition conduit and T pull out the tube end that eyelet welding connects and are provided with protuberance, and the external diameter of described protuberance pulls out the internal diameter in hole greater than T.
In the needle-valve syndeton described in the utility model, described protuberance is a bulge loop.
In the needle-valve syndeton described in the utility model, described protuberance is a plurality of protruding bubbles.Described protruding bubble is 2 to 4.
In the needle-valve syndeton described in the utility model, described protuberance is a plurality of protruding thorns.Described protruding thorn is 2 to 4.
In the needle-valve syndeton described in the utility model, described T pulls out the diameter in hole greater than the transition conduit diameter.
Needle-valve syndeton in the air-conditioning organ pipe assembly described in the utility model, by tube wall T is set and pulls out the hole at bottom tube, and the protuberance external diameter that makes transition conduit and T pull out the hole weld pulls out the internal diameter in hole greater than T, makes to reduce the welding leakage rate, can improve refrigerant influx in the pipeline simultaneously.
Description of drawings
Fig. 1 is the schematic diagram of needle-valve syndeton in the air-conditioning organ pipe assembly in the prior art;
Fig. 2 is the schematic diagram of the needle-valve syndeton in the air-conditioning organ pipe assembly described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
Needle-valve syndeton in the air-conditioning organ pipe assembly described in the utility model, as shown in Figure 2, comprise needle-valve 1 and the bottom tube 2 that connects thereof, the tube wall of described bottom tube 2 is offered T and is pulled out hole 3, described needle-valve 1 is welded in T by a transition conduit 4 and pulls out hole 3, be provided with protuberance 5 at transition conduit 4 and the tube end that T pulls out hole 3 welding, the external diameter of described protuberance 5 pulls out the internal diameter in hole 3 greater than T.
Particularly, in the utility model, described protuberance 5 can be bulge loop or protruding bubble or protruding thorn etc., and its version is not unique, and the external diameter that only need satisfy protuberance gets final product greater than the internal diameter that T pulls out hole 3.
When described protuberance 5 was protruding bubble, its quantity can be 2 to 4.
When described protuberance 5 was protruding thorn, its quantity can be 2 to 4.
As preferred implementation, the diameter that can T pulls out hole 3 is set to greater than transition conduit 2 diameters.
Needle-valve syndeton in the air-conditioning organ pipe assembly described in the utility model, by tube wall T is set and pulls out hole 3 at bottom tube 2, and protuberance 5 external diameters that make transition conduit 4 and T pull out hole 3 welds pull out the internal diameter in hole 3 greater than T, make and can reduce the welding leakage rate, can improve refrigerant influx in the pipeline simultaneously.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification and the embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
Claims (7)
