For the problems of above prior art, the object of the present invention is to provide a kind of more gas circuit rotary joints, knots
Structure advantages of simple can import the gas of a variety of air pressures simultaneously.
To achieve the goals above, the technical scheme is that
A kind of more gas circuit rotary joints comprising have: the fixing sleeve of fixed setting comprising have multiple entrance holes；Rotation
Axis is threaded through in the fixing sleeve；The inside of the rotary shaft offers a plurality of air flue for leading to an end face by side wall；It is described
Compartment of terrain is arranged with multiple spacers in rotary shaft；The spacer and the rotary shaft clearance fit；The spacer and the importing
Hole face；Air inlet is offered on the spacer；It is arranged with oil seal washer respectively on the two sides of the spacer, the rotary shaft.
As a kind of specific embodiment, that one end for offering air flue of the rotary shaft is connected with for connecting equipment
Flange；The stomata communicated with the air flue is offered on the flange.
Further, the rotary shaft is connected with retaining ring far from that one end of the flange.
Exhaust is also provided on the fixing sleeve between two adjacent entrance holes as a kind of specific embodiment
Hole；Region between the two neighboring spacer of gas vent face.
As a kind of specific embodiment, that one end close to the flange of the rotary shaft is arranged with snap ring.
A kind of more gas circuit rotary joints of the invention have following advantageous effects compared with the prior art:
Multiple entrance holes on the fixing sleeve are used to import the gas of different air pressures, and the gas of different air pressures respectively enters
In the annular housing surrounded by the two neighboring oil seal washer and the spacer, and then entered by the air inlet, and due to
The spacer and rotary shaft clearance fit, therefore, the gas entered by the air inlet can smoothly enter into the air flue, from
And deliver the gas to equipment.
In order to better understand and implement, the invention will now be described in detail with reference to the accompanying drawings.

Specific embodiment
Referring to Fig. 1, a kind of more gas circuit rotary joints, the present embodiment is to illustrate example with two gas circuit rotary joints comprising
Have: the fixing sleeve 1 of fixed setting, fixing sleeve 1 include the first entrance hole 110 and the second entrance hole 120；Rotary shaft 2, wears
In fixing sleeve 1；The inside of rotary shaft 2 offers the first air flue 210 and the second air flue 220 for leading to an end face by side wall；Rotation
Compartment of terrain is arranged with the first spacer 31 and the second spacer 32 in shaft 2, and the first spacer 31 and the second spacer 32 are led with first respectively
Enter 120 face of hole 110 and the second entrance hole；First spacer 31 and second set with 2 clearance fit of rotary shaft；First spacer
The first air inlet 310 is offered on 31, and the second air inlet 320 is offered on the second spacer 32；In the first spacer 31 and second
The two sides of spacer 32 are arranged with oil seal washer 4 in rotary shaft 2.
Rotary shaft 2 is connected to above-mentioned first air flue 210 and that one end of the second air flue 220 is connected with flange 5, and flange 5 is used for
It is connect with external equipment.
In order to improve the stability of the gas circuit rotary joint, rotary shaft 2 is connected with retaining ring 7 far from that one end of flange 5, rotation
That one end of the close flange 5 of shaft 2 is arranged with snap ring 6.
The working principle of the present embodiment is described below:
Fixing sleeve 1 is fixedly installed, and flange 5 and external equipment are affixed, and external equipment is by the first air flue 210 and the second air flue
220 gas supply.The first entrance hole 110 and the second entrance hole 120 above fixing sleeve 1 are separately connected the gas source of different air pressures, adjacent
Two oil seal washers, 4, two oil seal washers 4 between spacer and fixing sleeve 1 surround an annular airtight cavity, gas jointly
It can store wherein, guarantee does not leak outside.The gas of two kinds of different air pressures is separated and is transmitted well.Due to the first spacer
31 and second spacer 32 with 2 clearance fit of rotary shaft, when rotary shaft 2 is rotated with external equipment, the gas of two kinds of different air pressures
Body is entered by the first air inlet 310 and the second air inlet 320 respectively, then is transmitted respectively by the first air flue 210 and the second air flue 220
To external equipment.
In view of the abrasion of oil seal washer 4 will lead to the problem of collaborating, the first entrance hole 110 and the second entrance hole 120 it
Between, gas vent 130, the region between 130 face the first spacer 31 of gas vent and the second spacer 32, row are offered on fixed strip 1
The gas collaborated can be discharged in stomata 130 in time.
The present embodiment only introduces the rotary joint of two gas circuits, those skilled in the art it should be clear that three gas circuits or
The more gas circuits of person can still use design of the invention.
The invention is not limited to above embodiment, if not departing from the present invention to various changes or deformation of the invention
Spirit and scope, if these changes and deformation belong within the scope of claim and equivalent technologies of the invention, then this hair
It is bright to be also intended to encompass these changes and deformation.
