Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, gas circuit end face rotary seal structure comprising airtight closing disk 1, it is fixed in airtight closing disk 1 to connect
It is connected to sealing gland 2, sealing gland is connected by screw in airtight closing disk, is formed between 2 gentle seal disc 1 of sealing gland
The installation space 3 of the annular groove-shaped of one opening has in the installation space 3 equipped with sealing support ring 4, and the sealing supports
Ring 4 includes sealing ring body 40, and the left and right sides of sealing ring body 40 are equipped with T-slot 41, sealing ring is equipped in T-slot 41
42, sealing ring 42 is equipped with air hole 43, and the outer ring surface of the sealing ring body 40 is equipped with air inlet 44, the bottom of T-slot
The venthole 45 that face is connect with air inlet 44, the airtight closing disk 1 be equipped with it is corresponding with T-slot go out flow channel 10.
In the utility model, gas enters from the air inlet on the outer ring surface of sealing ring body, is then flowed into T-slot
It is interior, pressure is formed between sealing ring and T-slot, sealing ring is pushed, and ensures that sealing ring is pressed with airtight closing disk and sealing
Sealing effect between lid, further, the sealing support ring of the utility model is not as the gentle seal disc of sealing gland carries out
Rotation, reduces seal disc and the problem of aging occurs.

The steel ball 402 of gentle seal disc connection, the steel ball of setting slide between sealing ring body and sealing gland and airtight closing disk,
The friction between sealing ring body and sealing gland and airtight closing disk is reduced, frictional resistance is reduced.
Needle roller 403 is equipped between the inner ring surface and airtight closing disk 1 of the sealing ring body 40, the ball of setting is on the one hand
The support of an axial direction can be carried out to sealing ring body, while can also reduce the friction between sealing ring body and airtight closing disk
Power.
The sealing ring 42 includes sealing ring ontology 420, and the one side of sealing ring ontology is equipped with seal convexity, and 421 is close
Both sides up and down and the sealing ring ontology for sealing protrusion form sealing station terrace 422,1 on the sealing gland 2 and/or airtight closing disk
Equipped with corresponding with sealed step face and cooperation annular projection 430, annular projection is coordinated with sealing station terrace, is had preferable
Sealing effect.
In conclusion the utility model has the advantages that：
In the utility model seal ring body be fixedly connected by air inlet, during the work time, sealing support ring not with
It airtight closing disk and sealing gland rotates always, the friction between sealing ring and airtight closing disk and sealing gland can be reduced, after
And the problem of improving sealing ring aging.
