Working principle:
When tire patching, inflator pump is connect with 2 upper air interface 21 of self-mending liquid valve, the self-mending liquid being connected to out on liquid interface 22
Pipe 3 is connected with tire.At this moment, since seal plug 4 has blocked the inside of liquid interface 22 out, the space of bottle body 1 and self-mending liquid
It is not yet connected between pipe 3；Simultaneously as the exit of escape pipe 23 is provided with anti-backflow spool 5 and reset spring 6, resetting
Under the elastic force effect of spring 6, the sealing ring 5a on anti-backflow spool 5 blocks the outlet of escape pipe 23, effectively prevents bottle body 1
Self-mending liquid flows backward the blocking for into inflator pump and leading to air flue.
Start inflator pump, the sealing ring 5a on air pressure promotion anti-backflow spool 5 leaves the outlet (reset guide of escape pipe 23
The lower part of bar 53 is still located in escape pipe 23), the outlet passageway 23a in escape pipe 23 is connected with the inner space in bottle body 1,
Then self-mending liquid in bottle body 1 is pressed to out liquid interface 22 by air pressure, and seal plug 4 is pushed into plug and retracted in chamber 2a (originally certainly by pressure
Fluid infusion is disposable product), inner space and self-complementary liquid pipe 3 in bottle body 1 is connected, so that self-mending liquid be injected in tire.
During tire patching, if inflator pump is out of service, anti-backflow spool 5 will reset spring 6 effect under return, sealing ring 5a with go out
The outlet contact of tracheae 23 forms sealing.
The most preferred embodiment of the utility model has illustrated, the various change or remodeling made by those of ordinary skill in the art
All without departing from the scope of the utility model.
