Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
Embodiment one:
As depicted in figs. 1 and 2, a kind of insulator, including shell 1 are provided in the present embodiment, have at least two in shell 1
The item air flow circuit 2 mutually isolated using insulating materials, is correspondingly arranged at least two groups pipe interface, multi units tube on shell 1
Road interface is connect with more air pipe lines respectively.In the present embodiment, said for two air flow circuits 2 are set in shell 1
Bright, air flow circuit 2 can also be arranged three or more.
The first pipe interface 5 and the second pipeline that shell 1 is correspondingly arranged by insulating body 3, mounting base 4 and at least two groups connect
Mouth 6 forms.Wherein, the first pipe interface 5 is arranged on insulating body 3, and the second pipe interface 6 is arranged in mounting base 4, the
It is the air flow circuit 2 of perforation between one pipe interface 5 and the second pipe interface 6.
In the present embodiment, the generally spheroid of insulating body 3, mounting base 4 is plate-like structure, and insulating body 3 is in side
With the mounting plane 7 for cooperating with the first pipe interface 5, the other side is connect by transition part 8 with mounting base 4.Such as Fig. 1 institute
Show, mounting plane 7 is one, and multiple first pipe interfaces 5 are mounted on the same mounting plane 7.As shown in figure 3, installation is flat
Face 7 may be arranged as multiple, one the first pipe interface 5 of installation in each mounting plane 7.At four angles of mounting base 4
On be respectively arranged with a mounting hole 9, mounting hole 9 is counter sink, is fixedly connected by fasteners such as screws with fixing seat, fixation
Seat installation is on the car body.
In the present embodiment, the insulating body 3 and mounting base 4 of shell 1 are integrally formed by insulating materials, and air flow circuit 2 is also
It is formed when integrated molding, the first pipe interface 5, the second pipe interface 6 are the connector with internal thread, are connected with air pipe line
When connecing, pipe fitting is installed on the connector at the first pipe interface 5, the second pipe interface 6.First pipe interface 5 and second
Pipe interface 6 is directly embedded in insulating body 3 and mounting base 4 when insulating body 3 and mounting base 4 form, and such structure makes
It obtains between pipe interface and shell 1 without in addition setting sealing structure, simplifies the structure of insulator, also simplify insulator
Processing technology, reduce manufacture and material cost.
Since electric insulation depends on the distance between air pipe line inlet and outlet, and only need to realize between two groups of pipe interfaces
The isolation of air, therefore the insulator can reduce the spacing between two groups of pipe interfaces as much as possible, two groups of pipelines connect
As long as the spacing between mouthful guarantees that Standard tubing fittings (the straight coupling and elbow etc.) form connecting with air pipe line and installation are empty
Between requirement, be conducive to reduce insulator overall volume, and then be conducive to save installation space, improve installation effectiveness, drop
Low pipeline arranges difficulty.
