The second sealing ring 10.9 is equipped between 10.8, described two jump-ring slot 10.2.7；Second sealing ring, 10.9 both ends respectively with
Two circlips 10.8 contact, and outer wall is contacted with 10.2 inner wall of inner support axis.It, can be hard by implementing above-mentioned technical proposal
When pipe is connect with gas-tpe fitting 10, by the clearance seal between tracheae and inner support axis 10.2, to further increase airtight effect
Fruit.And the structure is convenient for changing sealing ring.
The beneficial effects of the present invention are: more tracheaes can be also turned on, air inlet pipe and an air outlet pipe number is selected as needed
Amount, meet it is single into have more, mostly into having more or mostly into the functional requirement singly gone out；Heel row can be mixed according to by the multiple gases entered
It out, and at most can three gas outlets of simultaneous selection；It can be adapted to that hardness is larger and the lesser two kinds of tracheaes of hardness；Difference can be adapted to
The hose of size；High reliablity when connecting with tracheae, air-tightness is good, and can be with fast assembling-disassembling.
