Steel ball.
When needs use burner, the hand-holdable above-mentioned briquetting 13 of user, by above-mentioned pressure
Block 13 presses toward above-mentioned valve body 1, now, and briquetting 13 meeting being fastened on above-mentioned spool 3
Band movable valve plug 3 is internal mobile to valve body 1.When user will be arranged on briquetting 13 and valve master
When spring 17 between body 1 is compressed to maximum, above-mentioned spool 3 moves in valve body 1
To maximum, now, the position of the key pin 4 being radially arranged on spool 3 will be above card access surface
The position of 9.Simultaneously, when briquetting 13 is pressed by user, briquetting 13 1 side
Wear the dynamic spool 3 fastened with it direction in valve body 1 to move, on the other hand, briquetting
13 by driving reset push rod 18 mechanism, i.e. briquetting 13 while band movable valve plug 3 moves,
Also push rod 18 will be pressed, and make push rod 18 along the direction being perpendicular to air inlet valve body 5 axis
Move in air inlet valve body 5.
The end of the above-mentioned push rod 18 being slidably matched with inclined tab 25 is taper, push rod 18 end
The tapering of taper is consistent to the angle of pushing block 11 inner inclination with inclined tab 25.
Above-mentioned push rod 18 is moved to the direction within air inlet valve body 5 by the pressure of briquetting 13,
And be slidably matched by the inclined tab 25 of the end of taper and pushing block 11, by inclined-plane move former
Reason, the power that push rod 18 is perpendicular to air inlet valve body 5 axis direction changes into pushing block 11 along air inlet
The power that valve body 5 axis direction moves.
The power that above-mentioned pushing block 11 is applied by push rod 18 in secondary inlet chamber 7 along air inlet valve body 5
Axis direction moves, and touches mutually with elastic packing bar, makes elastic packing bar by pushing block 11
Thrust and compress, thus open main inlet chamber 6.
The body of rod 26 of above-mentioned elastic packing bar is hollow lever 26, above-mentioned articulated joint 28 and bar
Body 26 clamping.
When the hinged block 27 of elastic packing bar is pressed by pushing block 11, hinged block 27 will
The power that pushing block 11 applies passes to compression spring 30, makes compression spring 30 under force
It is compressed, so that diaphragm seal 29 separates with sealing land 10, makes in main inlet chamber 6

Circulation air cavity 8.
Then, user rotates briquetting 13.While briquetting 13 rotates, fasten with it
Spool 3 rotates the most simultaneously, makes the key pin 4 being radially arranged on spool 3 rotate to card access surface
Above in the of 9.Now, for avoiding user to be rotated excessively by briquetting 13, it is arranged on inwall
Projection 15 rotates to time above card access surface 9 at key pin 4, above-mentioned projection 15 just be arranged on valve
Limited block 16 clamping in main body 1.
While above-mentioned briquetting 13 band movable valve plug 3 rotates, by being arranged on seal disc 38 end
The inserted block 42 in face drives adjustment pin 50 synchronous rotary coordinated with its grafting.
Above-mentioned adjustment pin 50 is and supporting member 52 threaded being fixed on housing 2.
When adjustment pin 50 rotates under the drive of spool 3, adjustment pin 50 is along valve body 1 axis
Direction is moved to the direction within housing 2.Now, adjustment pin 50 will drive setting
Injection baffle plate 51 in regulation moves to the direction within housing 2 together, and is arranged on and props up
Spring 48 between support plate 40 and spring holder 49 can be compressed.Above-mentioned injection baffle plate 51 is being adjusted
Separating with valve body 1 under the drive of joint pin 50, now, circulation air cavity 8 is easy in housing 2
Space be connected, gas will pass through injection baffle plate 51 and valve body 1 between gap enter
Enter in housing 2, and enter into burner by the venthole 47 being arranged on housing 2,
The gas of burning is provided for user.
The present embodiment above-mentioned all of " O " RunddichtringO can use fluorubber or nitrile rubber or
Silicone rubber is made, and wherein, " O " RunddichtringO of the present embodiment uses fluorubber to make.
And when Manual air control valve of the present invention closed by needs, only briquetting need to be reversely rotated again
13.Now, the key pin 4 being radially arranged on spool 3 along with spool 3 rotation with
Card access surface 9 departs from, and above-mentioned briquetting 13 is by the spring being arranged between briquetting 13 and valve body 1
Reset under the effect of the reverse elastic force of 17, and the power that above-mentioned push rod 18 applies at briquetting 13 disappears
After mistake, by back-moving spring 19 opposition reset, and with baffle ring 12 clamping.
After push rod 18 resets, the thrust that pushing block 11 applies without push rod 18, by compressing
The opposition return of spring 30, and make diaphragm seal 29 weight being arranged on hinged block 27
Newly seal with sealing land 10 and coordinate.
Above-mentioned spool 3 under the reverse rotation of briquetting 13 moving along valve body 1 axis direction,
Direction along valve body 1 axis is moved outside valve body 1, above-mentioned is arranged on seal disc 38
On " O " RunddichtringO 34 with coordinate inclined-plane 37 seal coordinate.
Above-mentioned adjustment pin 50 rotates again reset along with the reverse rotation of spool 3, above-mentioned sets
Put the spring 48 propping up between support plate 40 and spring holder 49 and discharge the elastic force compressed, by bullet
On spring dish 49 push up, " O " RunddichtringO 33 being arranged in seal groove 39 all the time with injection baffle plate
51 seal cooperation.By the jacking of above-mentioned spring 48, make injection baffle plate 51 and valve body 1
Seal and coordinate.
Now, inlet chamber and circulation air cavity 8 and circulation air cavity 8 are with the space within housing 2 all
To block, gas cannot arrive the space within housing 2, i.e. from inlet chamber through circulation air cavity 8
Realize the closedown of the present invention.
The above is only the preferred embodiment of the present invention, it is noted that lead for this technology
For the those of ordinary skill in territory, on the premise of without departing from the technology of the present invention principle, it is also possible to
