Journey schematic diagram,
As shown in Figure 4, the schematic diagram rotated for rotary handle 603 of the present invention.Wherein rotary handle 603 is revolved by different angle respectively
When turning, workflow of the invention is as described below：
1）As shown in figure 5, the rotary handle 603 does not connect in 0 degree of position, hydrogenation rifle with hydrogen cell automobile hydrogenation mouth 1
Connect, be now hydrogenated with rifle exhaust gas inside pipeline UNICOM, air inlet pipeline is closed, and hydrogenation rifle is generally in closed mode；
As shown in fig. 6, rotating rotary handle 603 to 45 spends position, hydrogenation rifle insertion hydrogen cell automobile hydrogenation mouth 1, hydrogenation
The handle chassis 602 of rifle drives sliding sleeve 201 to move forward, and forces gripping dogs 2 to overcome the elastic force of steel wire collar 202 to go forward side by side conduct to receipts
Contracting, it is engaged with hydrogen cell automobile hydrogenation 1 trapezoidal annular groove of mouth.Meanwhile Outlet check valves core 4 is hydrogenated with hydrogen cell automobile
Mouth 1 overcomes the elastic force of outlet spring to be moved rearwards after mutually contradicting, Outlet check valves core 4 is opened by top, opens and is hydrogenated with rifle escape pipe
Road path, now gas exhaust piping open；
As shown in FIG. 7 and 8, rotate rotary handle 603 to 90 again to spend, camshaft 601 rotates simultaneously, driving operation valve element 502
After move, now operate valve element 502 slowly oppress floating seal tapered sleeve 805 and further compressing inlet one-way valve core 801 overcome into
The active force of mouth spring 804, forces it to be moved rearwards, and inlet one-way valve core 801 is slowly moved with aerating seal assembly 802 to divide
From the exhaust channel of now slowly closing exhaust valve pocket 806 simultaneously prepares to open aerating path；
As shown in Figures 9 and 10, it is rotated further rotary handle 603 to rotate simultaneously from 90 degree to 180 degree position, camshaft 601, drives
Operation valve element 502 continues to be moved rearwards, and now operates valve element 502 and the taper-face contact of floating seal tapered sleeve 805 and is fully sealed simultaneously
Further oppress inlet one-way valve core 801 overcome the active force and high pressure hydrogen of entry springs 804 caused by sealing force, force into
Mouth nonreturn valve core 801 is moved rearwards to be kept completely separate with the motion of aerating seal assembly 802, now inlet one-way valve core 801 and aerating
Path UNICOM, aerating path is integrally formed in the present invention, while exhaust channel is closed.
Now, hydrogen water conservancy diversion valve body 701, water conservancy diversion valve element 807, inlet one-way valve core 801, floats through air induction hose joint 703
Dynamic sealing tapered sleeve 805, operation valve element 502 enter in outlet valve body 401, full of valve chamber, form high pressure chest；In gas pressure power

Radial rotating, prevent from taking off rifle caused by improper operation during filling hydrogen, the security incident such as draw guns by force；High pressure hydrogen passes through
Outlet check valves core 4 is crossed into after being hydrogenated with mouth, the check valve inside hydrogen cell automobile can be opened under gas pressure power, it is past
Filling hydrogen in automobile high-pressure cylinder.
2）When Hydrogen Vapor Pressure is equal with the pressure in hydrogenation rifle in hydrogen cell automobile steel cylinder, the hydrogenation of automobile side
Mouth rear end check valve can close automatically under the force of a spring, and filling hydrogen stops.
3）, it is necessary to which operation of being taken arms or drawn guns, at this moment, being hydrogenated with rifle has one after being hydrogenated with generator terminal and stop signal occur
Point residual high pressure hydrogen, it is necessary to which operation is exhausted after could draw guns or take arms safely, specific implementation process is：Rotary handle
603 rotate backward to 90 degree of positions, and by driving operation valve element 502 to move forward, inlet one-way valve core 801 is in entry springs
Move forward under 804 rebound effect and be bonded with aerating seal assembly 802, cut-out inlet one-way valve core 801 and hydrogenation path
Between gas circuit connection, now turn off hydrogen source；
Again continue to rotate backward handle to 45 degree of positions, operation valve element 502 continues to move along, with floating seal tapered sleeve 805
Depart from, open the exhaust channel of exhaust valve pocket 806, hydrogenation rifle inner high voltage hydrogen is discharged into concentration emptying by exhaust hose joint
In pipeline, safety vent is carried out, ensures the safety of operating environment, rotary handle 603 to 0 is finally rotated again and spends, be hydrogenated with rifle
Handle chassis 602 returns to initial position, and sliding sleeve 201 moves afterwards under spring action, and the radial dilatation of gripping dogs 2 is opened, with adding
The failure of hydrogen mouth trapezoidal annular groove interlocking pattern, hydrogenation rifle Outlet check valves core 4 and hydrogenation mouth joint by outlet acting force of the spring to
Sinciput opens separation, and Outlet check valves core 4 is combined with inlet seal component, closes the outlet of hydrogenation rifle, extracts hydrogenation rifle.
