Boss 601 is only locked boss 502B by second and is blocked, and cannot achieve rotation, is only locked by plectrum 6.
It in the present embodiment, is valve body closed position at the first locked groove 501A, first only locks at boss 502A for high 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, and lower end is arranged in the accommodating chamber 123 of spool 12, and cooperates 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 mobile
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.
It further include split washer 2, the first gasket 3, the first elastic component 4, third elastic component 11, limit film 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, limit film 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
The lower end cap of three elastic components 11 abuts against outside the accommodating chamber 123 of spool 12, and with limit film 13, upper end with dial, 6 abut against.
In the present embodiment, the first elastic component 4 can be spring.
It can also include that steel ball 161, feel adjustment spring 162 and feel adjust 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 adjusts 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 adjust screw and cooperate, each fire when adjusting firepower
There is feel feedback at power gear, user is facilitated to understand firepower size in time, it is easy to operate.
The working principle of plug valve in the present embodiment is illustrated below with reference to Fig. 2-11.
In valve body closed position, the upper end of plectrum 6 is contacted under the effect of third elastic component 11 with the face B 504B in valve deck 5, is dialled
Piece boss 601 is caught in the first locked groove 501A, and need to press shaft 1 and move down plectrum 6 could unlock, and realizes that shaft 1 rotates;
When shaft 1 goes to the first only lock position boss 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 face 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 face the B 504B of valve deck 5.
When small fire is tuned up fire, shaft 1 and plectrum 6 are reversely rotated, 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 face the B 504B of valve deck,
The face the A 504A height for reaching valve deck, which can just continue to realize, to be reversely rotated, this pressing position and auxiliary flow feed position consistency, 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, moves down mandril 7,1 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 ring 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 temporarily increases, and completes combustion gas auxiliary supply, so that changeover portion is stablized burning, avoid and return in firepower adjustment process
Fiery phenomenon;
When the revocation of 1 pressing force of shaft, shaft 7 is upward under the first elastic component 4 and the effect of 11 pretightning force of third elastic component
Mobile set back is set, and plectrum 6 restores under the effect of 11 pretightning force of third elastic component and 5 contact condition of valve deck, and mandril 7 is second
Elastic component 8 moves up under acting on, and sealing is realized in 7 bottom of mandril and the cooperation of spool 12, and auxiliary aperture 121 is blocked, assisted
Passageway break terminates combustion gas and temporarily supplies.
In other embodiments, the pressing driving method of shaft 1 during the rotation adjustment process can also be driven using pulling
Flowing mode substitution;When the revocation of 1 motive force of shaft, 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 utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
