Description
Technical field
The utility model is related to a kind of joint design, specifically refers to a kind of joint design of air-conditioning refrigerant pipeline.
Background technology
At present, in the refrigerant line of coach air conditioner, its joint is connected only one of which O-ring with end and is sealed, and
And be mounted in the O-ring groove of end.But this connected mode typically can be only applied to R134a pressure in 1.5MPa-
In the system of 1.8MPa, when system of the R407d pressure in 2.3MPa-2.6MPa is applied to, easily there is asking for leakage in joint
Topic.It would therefore be desirable to a kind of structure is improved, the joint design of high pressure systems is can apply to.
Utility model content
The purpose of this utility model is to provide for a kind of pipeline joint structure, and the joint design is reasonable in design, is suitable for
In high pressure systems, good airproof performance, joint cross-sectional area is big, and refrigerant flow is high.
In order to achieve the above object, the utility model provides following technical scheme：A kind of pipeline joint structure, including end
End and joint, the end include bigger diameter end, miner diameter end and protruding end, and the bigger diameter end is connected with miner diameter end by protruding end,
The external diameter of the protruding end is more than the external diameter of miner diameter end, what the bigger diameter end, miner diameter end and protruding end were integrated, and the joint sets
There are connection end and the groove ends being connected with connection end, the internal diameter of the connection end is less than the internal diameter of groove ends, the connection end
Internal diameter is less than or equal to the external diameter of miner diameter end, and the axial length of the connection end is equal to the axial length of miner diameter end, the miner diameter end
Outer O-ring is provided with protruding end junction, is that groove ends are provided with interior O-ring, the connection end is provided near the side of protruding end
Compression end, the external diameter of the internal diameter less than protruding end of the compression end, and more than the internal diameter of connection end, the axial direction of the compression end is long
Diameter of the degree less than outer O-ring.
It is further preferred that the miner diameter end outer wall is provided with external screw thread, the connection end inwall is provided with internal thread, and outer spiral shell
Line is engaged with internal thread.
It is further preferred that the end passes through clamp connection with joint.
The beneficial effects of the utility model：The joint design is reasonable in design, while setting two O-rings, is adaptable to height
Pressure system, good airproof performance, joint cross-sectional area is big, and refrigerant flow is high.

Specific embodiment
We are described further with reference to accompanying drawing to a kind of pipeline joint structure described in the utility model below.
As shown in fig. 1, a kind of pipeline joint structure of the present embodiment, including end 1 and joint 2, the end 1 includes
Bigger diameter end 11, miner diameter end 12 and protruding end 13, the bigger diameter end 11 are connected with miner diameter end 12 by protruding end 13, the protruding end
13 external diameter is more than the external diameter of miner diameter end 12, what the bigger diameter end 11, miner diameter end 12 and protruding end 13 were integrated, the joint 2
Connection end 21 and the groove ends 22 being connected with connection end 21 are provided with, the internal diameter of the connection end 21 is less than the internal diameter of groove ends 22,
, less than or equal to the external diameter of miner diameter end 12, the axial length of the connection end 21 is equal to miner diameter end 12 for the internal diameter of the connection end 21
Axial length, the miner diameter end 12 is provided with outer O-ring 5 with the junction of protruding end 13, is that groove ends 22 are provided with interior O-ring 6, described
Connection end 21 is provided with compression end 3 near the side of protruding end 13, and the internal diameter of the compression end 3 is less than the external diameter of protruding end 13, and
More than the internal diameter of connection end 21, the diameter of the axial length less than outer O-ring 5 of the compression end 3.The joint design is being used
When, outer O-ring 5 is first enclosed within the junction of miner diameter end (12) and protruding end 13, interior O-ring 6 is embedded in groove ends 22, then
Miner diameter end 12 is inserted into connection end 21 so that the ends contact groove ends 22 of miner diameter end 12, while the contact projection end of compression end 3
13, outer O-ring 5 is compressed, improve sealing.Such setting can ensure the pipe thickness of end 1, adapt to high pressure systems.
In the present embodiment, the outer wall of the miner diameter end 12 is provided with external screw thread, and the inwall of the connection end 21 is provided with internal thread, and outward
Screw thread is engaged with internal thread.The end 1 passes through clamp connection with joint 2.Two kinds of connected modes can be used simultaneously, it is ensured that
The fastness of connection.
Protection domain of the present utility model is not limited to above example and its conversion.
