Described main valve body 1 upper end is provided with valve gap 11, and valve gap 11 is provided with slide guide bar 113, is provided with axially extended through hole 114 in the slide guide bar 113; Main valve plug 108 upper ends are connected with hand switch spare 4, and hand switch spare 4 is installed in the described through hole 114, and hand switch spare 4 middle parts are provided with annular groove 41; Also be provided with the guiding slip groove 111 that is communicated with through hole 114 on the slide guide bar 113, be set with sliding sleeve 112 on the slide guide bar 113, sliding sleeve 112 is provided with and passes the screw 122 that described guiding slip groove 111 extend in the described annular groove 41 and can circumferentially slide within it, described sliding sleeve 112 sidewalls are provided with projection 123, and side valve body 2 is provided with by projection 123 slips and pushes the manual overvide 5 of control electromagnetic valve core 203 actions.Manual overvide 5 comprises the push rod 51 of one end roof pressure below projection 123, push rod 51 the other ends are located in the side valve body 2 and the upper end of pushing up electromagnetic valve core 203, be coated with snap ring 52, support pad 53 on the push rod 51 and be located at snap ring 52 and support pad 53 between described push rod 51 is resetted Returnning spring 54.By pressing down sliding sleeve 112, the projection 123 on the sliding sleeve 112 presses down push rod 51, and push rod 51 backs down electromagnetic valve core 203, thereby makes combustion gas flow to connecting passage 202 from storage chamber 201.Drive main valve plug 108 by rotation manual switch member 4 and rotate, connecting passage 202 is communicated with spool chamber 104.
Modulating valve 302 comprises valve rod 312, the projection 322 of projection about valve rod 312 upper ends are provided with, projection 322 is inserted in the axially extended breach 118 in main valve plug 108 lower ends, modulating valve 302 lower end screw threads are connected with can respond to combustion temperature and promote described modulating valve 302 actions regulates the dynamical element 6 of gas flow, be coated with the valve block 332 of combustion gas break-make between control described spool chamber 104 and the described outlet chamber 301 on the valve rod 312, be provided with roof pressure valve block 332 between valve block 332 and the dynamical element 6 and make the supported spring 342 that seals between itself and the main valve body 1.
Course of action of the present utility model is as follows:
Complete closed state: have combustion gas to enter into storage chamber 201 in the gas-entered passageway 101, cut off air-flow by electromagnetic valve core 203 but store between chamber 102 and the outlet passageway 103.
Connect main fire, enter temperature automatically controlled state: by pressing down sliding sleeve 112, the projection 123 on the sliding sleeve 112 presses down push rod 51, and push rod 51 backs down electromagnetic valve core 203, thereby makes combustion gas flow to connecting passage 202 from storage chamber 201.Drive main valve plug 108 by rotation manual switch member 4 and rotate, connecting passage 202 is communicated with spool chamber 104.The rotating band ovable valve stem 312 of main valve plug 108 rotates, because valve rod 312 and power lever 61 are threaded, valve rod 312 rotates valve rod 312 is moved down, and moves down thereby drive valve block 332, is communicated with spool chamber 104 and outlet chamber 301, connects the big flow of main fire.Regulate adjustable screw main part 16 this moment again and connect main fiery small flow, and enter temperature automatically controlled state.
The realization of main fiery small flow: after connecting spool chamber 104 and outlet chamber 301, this moment configuration switch dynamical element 6 detect ambient temperature be on the setting temperature in limited time, the action of switch dynamical element 6 heat expansions is expanded, valve rod 61 is moved up drive valve block 332 to move up, thereby make spool chamber 104 and the big flows of outlet chamber 301 main fire obstructed.Adjustable screw main part 16 has been connected main fiery small flow, and combustion gas flows to main fiery small flow passage 15 by spool chamber 104, enters then in the outlet chamber 301.Enter main fiery small flow state.
The realization of the big flow of main fire: after connecting spool chamber 104 and outlet chamber 301, when switch dynamical element 6 detects ambient temperature when spending less than the setting temperature upper limit 5, switch dynamical element 6 shrinkages action is shunk, make valve rod 61 move down drive valve block 332 and move down, connect spool chamber 104 and outlet chamber 301.The distance that valve block 332 moves down increases, and combustion gas just increases from the flow that spool chamber 104 flows into outlet chamber 301, makes flame of combustion become big.
Automatically regulate the process of air-flow size: switch dynamical element 6 is to detect ambient temperature when lower than setting temperature, just starts safety valves for gas work, is maintained to certain level to guarantee ambient temperature.When switch dynamical element 6 detects ambient temperature is to prescribe a time limit on the setting temperature, the not conducting of main passage of spool chamber 104 and outlet chamber 301 at this moment, behind the adjustable screw assembly of establishing in connection spool chamber 104 that combustion gas is provided with on main valve body 1 and the fiery small flow passage 15 of the master of outlet chamber 301 16, spool chamber 104, outlet chamber 301 are communicated with, make valve body be in main fiery small flow combustion regime, behind the constant temperature certain hour, beginning slowly descends ambient temperature at this moment.
When switch dynamical element 6 detects ambient temperature when spending less than the setting temperature upper limit 5, switch dynamical element 6 is made contractive action, switch dynamical element 6 shrinkages action is shunk, making valve rod 61 move down drive valve block 332 moves down, connect spool chamber 104 and outlet chamber 301, the distance that valve block 332 moves down increases, and combustion gas just increases from the flow that spool chamber 104 flows into outlet chamber 301, makes flame of combustion become big.
When switch dynamical element 6 detects ambient temperature and does not reach the minimum of setting temperature yet, the switch dynamical element 6 main reaction forces that are subjected to supported spring 342 continue to do contractive action, drive valve block 332 and continue down motion, the air-flow by the air outlet is increased, realize big fire burns.
Otherwise when temperature rose, switch dynamical element 6 was made turgor movement, and switch dynamical element 6 reduces the air-flow of air outlet because the elastic force effect of supported spring 342 is up moved, and realizes little fire burns, reduces temperature.
