10, so that 12 lower end combustion gas of spool is isolated with valve body external coordination, realizes sealing, prevent gas leakage.
As shown in figs. 9-10, plectrum 6 is arranged in 12 upper end of spool.The shape of plectrum 6 is circle, and directed circle is set on plectrum 6
All outer plectrum boss 601 outstanding.Third elastic component 11, the preload of third elastic component 11 are provided between plectrum 6 and spool 12
Power makes plectrum 6 realize reset.Plectrum boss 601 can rotate.In the present embodiment, third elastic component 11 can be spring.
As shown in Fig. 2-3, Figure 10, valve deck 5 is mounted on 15 top of valve seat.It is provided on valve deck 5 logical for plectrum boss 601
The the first locked groove 501A and the second locked groove 501B crossed, and for stop plectrum boss 601 first only lock boss 502A and
Second only lock boss 502B, first only lock boss 502A and second only lock between boss 502B that there are gaps 503.Valve deck 5 or so
Both sides are also respectively provided with a through-hole 505, and the through-hole 506 is corresponding with the through-hole 155 on valve seat 15.In the present embodiment, it can adopt
The through-hole 505 of valve deck 5 is sequentially passed through with screw, through-hole 155 on valve seat 15, valve deck 5 is fixed on valve seat 15.
Plectrum boss 601 can pass through from gap 503, realize rotation, with turn to second only lock boss 502B when, plectrum
Boss 601 is only locked boss 502B by second and is blocked, and rotation is cannot achieve, and is only locked by plectrum 6.
In the present embodiment, at the first locked groove 501A it is valve body closed position, first only locks at boss 502A for big fire
Power stops lock position, is small fire file location at the second locked groove 501B.
As shown in Fig. 6-7, Fig. 9, Figure 11, the groove 101 for placing split washer is provided among shaft 1, lower end is set
There is spring stand 102.Shaft 1 passes through valve deck 5, lower end to be arranged in the accommodating chamber 123 of spool 12, and coordinates with accommodating chamber 123
It is clamped and realization and 12 synchronous rotary of spool, while being abutted against with mandril 7.In the present embodiment, shaft 1 drives mandril 7 to move
When, 7 lower end groove 701 of mandril, spool auxiliary aperture 121 are aligned and are connected to the first auxiliary air inlet channel 151B of valve seat, this
When accessory channel be connected to.
Further include split washer 2, the first gasket 3, the first elastic component 4, third elastic component 11, banking stop such as Fig. 2, Figure 11
13 and gear shifting device 14, wherein the first elastic component 4, the first gasket 3 are inserted in shaft 1 from bottom to top, 4 lower end of the first elastic component with
Valve deck 5 abuts against, will be on the groove 101 of 2 package packing rotating shaft 1 of split washer.Gear shifting device 14, banking stop 13 are successively set on spool 12
Upper end, the side of gear shifting device 14 is equipped with concave tooth 142 and double wedge 141, and corresponding with the screwing through hole 156 on valve seat 15.The
Three elastic components, 11 lower end is sleeved on outside the accommodating chamber 123 of spool 12, and is abutted against with banking stop 13, upper end with dial, 6 abut against.
In the present embodiment, the first elastic component 4 can be spring.
Can also include steel ball 161, feel adjustment spring 162 and feel adjusting screw 163, wherein steel ball such as Figure 11
161 one end and the concave tooth 142 of gear shifting device 14 abut against, and the other end is abutted with feel adjustment spring 162；Feel adjusting screw
163 pass through 15 screwing through-hole 156 of valve seat, and steel ball 161 and feel adjustment spring 162 are fixed on gear shifting device 14.In this reality
It applies in example, gear shifting device gear, steel ball, feel adjustment spring and feel adjusting screw cooperate, each fiery when firepower being made to adjust
There is feel feedback at power gear, user is facilitated to understand firepower size in time, it is easy to operate.
The operation principle of plug valve in the present embodiment is illustrated with reference to Fig. 2-11.
In valve body closed position, the upper end of plectrum 6 contacts under the effect of third elastic component 11 with the faces B 504B in valve deck 5, dials
Piece boss 601 is caught in the first locked groove 501A, and need to press shaft 1 plectrum 6 is made to move down could unlock, and realizes that shaft 1 rotates；
When shaft 1 goes to the first only lock boss positions 502A under pressing state, plectrum boss 601 is only locked convex by first
Platform 502A is blocked, and realizes that maximum fire is only locked, and need to cancel 1 pressing force of shaft, plectrum 6 is under the effect of third elastic component 11, plectrum 6
It is contacted with the faces A 504A in valve deck 5, plectrum boss 601 can pass through from gap 503, realize rotation；
When shaft 1 goes to small fire file location, plectrum boss 601 directly slides into second under the effect of third elastic component 11 and only locks
Slot 501B, and plectrum 6 contacts under the effect of third elastic component 11 with the faces the B 504B of valve deck 5.
When small fire is tuned up fire, shaft 1 and plectrum 6 reversely rotate, when boss 502B is only locked in rotation to second, plectrum boss
601 by second only lock boss 502B blocks, cannot achieve rotation, shaft 1 need to be pressed, plectrum 6 is allowed to fall off the faces the B 504B of valve deck,
Reaching the faces the A 504A height of valve deck can just continue to realize that reverse rotation, this pressing position feed position consistency with auxiliary flow, this
When accessory channel be connected to；
When pressing shaft 1, there are pretightning force, 11 pretightning forces of third elastic component for the first elastic component 4 and third elastic component 11
Upwards firmly by plectrum 6, while 1 lower end of shaft applies pressure to 7 upper end of mandril, and mandril 7 is made to move down, 1 down stroke of shaft with
It is consistent that mandril 7 moves down stroke, and 8 pretightning force of the second elastic component increases, and 7 lower end groove 701 of mandril is made to enter 12 lower end combustion gas of spool
Cavity 122 flows to the outer shroud outlet 151 of valve seat 15, to realize at this point, combustion gas flows through accessory channel from 12 lower end of spool
Gas flow increases temporarily, completes combustion gas auxiliary supply, so that changeover portion is stablized burning, avoid and returned in firepower adjustment process
Fiery phenomenon；
When 1 pressing force of shaft cancels, shaft 7 is upward in the case where the first elastic component 4 and third elastic component 11 pre-tighten force effect
Mobile set back is set, and plectrum 6 restores in the case where third elastic component 11 pre-tightens force effect and 5 contact condition of valve deck, and mandril 7 is second
Elastic component 8 moves up under acting on, and 7 bottom of mandril realizes that sealing, auxiliary aperture 121 are blocked, assisted with the cooperation of spool 12
Passageway break terminates combustion gas and supplies temporarily.
In other embodiments, pressing type of drive of the shaft 1 in rotating adjustment process can also be used to pull and be driven
Flowing mode substitutes；When 1 motive force of shaft cancels, mandril 7 moves under the effect of the second elastic component 8, at this point, the mandril 7 is most
Lower end can also continue to be connected to 12 blow-by of spool, accessory channel, and then play the gas flow of enhancing outlet passageway, make to cook
Firepower of preparing food is more sufficient, meets the needs of user's moment high flame.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to the protection model of the present invention
It encloses.
