Body passage b170 is entered in the air cavity b of gas injection air cavity 150, and at the same time, gas passage a and bleeder port 420b, center are vented
Hole 410a, exhaust passage 210 are connected, and the air cavity a and outside atmosphere for realizing gas injection air cavity 150 are connected, and high pressure is not present in air cavity a
Gas so that gas-stopping spring 550 promotes ring set 540 of holding one's breath to block stomata c530a;
S5:In above-mentioned steps S4, the gases at high pressure that are continuously applied by the air cavity b for entering to gas injection air cavity 150 and by
Gases at high pressure promote the air tube seat 510 of gas injection component 50 to be discharged into contract, and by the gas in air cavity a to air, you can
Complete the action of automatic accomodation needle tubing 520.
In above-mentioned step S4, valve element 40 towards regulation and control air cavity 140 control pressure port direction motion process in, triggering lock
Close mechanism 30 with it to match, realize to locking of the locking mechanism 30 to valve element 40.
When completing to rectify and improve inflation work, it is only necessary to which automatic ejection type can be achieved in the gland 320 for pressing locking mechanism 30
The reset of air valve, in the process, locking bar 310 is vertically with the central axial direction of mandrel 410 to contract so that lock tooth 310a with
Locked groove 410b is disengaged from relation, in the presence of pressure-controling spring 450, promotes valve core reset.
More perfectly, the air inlet port for regulating and controlling air cavity 140 is threaded with spiral cover 110, more specifically, regulates and controls air cavity
140 air inlet port is also threaded with adapter sleeve 120, and the spiral of spiral cover 110 is connected to the suspension end of adapter sleeve 120, connection
Cover to be provided with 120 centers and extend to the regulation and control inner chamber of air cavity 140 and for limiting air inlet of the valve element 40 towards regulation and control air cavity 140
The limited post of port motion, its act on be in order to avoid valve element 40 departs from the presence of pressure-controling spring 450, and can be with
Determine the original state of valve element 40.
More perfectly, the gas injection of gas injection air cavity 150 it is open-ended setting and opening be threaded with end cap 130,
Suspension ring are may be provided with end cap 130;It is easy to the handling of gas injection component 50 by dismantling end cap 130.
