Description
[technical field]
The utility model relates to a kind of gas ignition switch.
[background technology]
Since the gas ignition switch of existing external pressure in use gaseous-pressure generally than higher, the sealing property of the needle of gas valve and the syndeton of gas nozzle is relatively poor, gas seal has wearing and tearing and can't seal, so just the gas ignition switch need be dismantled, change gas seal member, otherwise be easy to generate disappointingly, so just be easy to generate that combustion gas leaks even the danger of gas explosion.The gas valve body switch that has adopts the structure of plug valve, though solved the problem of losing heart to a certain extent, because plug valve wearing and tearing for a long time between seal head and the nozzle in use for some time, the gap is just strengthened, thereby strengthened leakage, particularly under the situation of high pressure.
[summary of the invention]
The purpose of this utility model is to provide a kind of good seal performance, safety durable, gas ignition switch simple in structure at the deficiency of existing burnt gas switch.
The purpose of this utility model is achieved in that
A kind of gas ignition switch comprises the valve body that is made of left and right valve body, combustion gas controlling organization, gas ignition mechanism, blast tube, nozzle; The combustion gas controlling organization comprises rotating shaft, and with the spool that is connected with rotating shaft, spool is threaded with valve body, and can be in valve body move left and right, it is characterized in that the rear end of seal spool head is fastened in the spool bore of spool, the front end of seal spool head is then with sealed nozzle.
Aforesaid a kind of gas ignition switch is characterized in that seal spool head front end is a sharp cone distal, and sharp cone distal is plugged in the nozzle bore sealed nozzle.
Aforesaid a kind of gas ignition switch is characterized in that the front end of seal spool head also can be designed to a bellmouth, and the end that nozzle and seal head join is provided with conical pipe, and conical pipe can be plugged in the bellmouth sealed nozzle.
Aforesaid a kind of gas ignition switch is characterized in that gas ignition mechanism comprises shifting block, piezoelectric ceramics, electronic card, hammer, the spring on the spool that is arranged on the combustion gas controlling organization.
Aforesaid a kind of gas ignition switch is characterized in that blast tube comprise clearance channel between air inlet pipe, spool and the valve body, the air inlet pipe hole that communicates with spool bore in the spool, hole, the nozzle bore that spool bore communicates with clearance channel.
Advantage of the present utility model is simple in structure, good seal performance, safety durable; And the seal spool head sealing that the utility model adopted is strong, durable, need not change for a long time, and the certain protection effect has also been played in sealing, the security of valve body.

[specific embodiment]
A kind of gas ignition switch comprises the valve body 3 that is made of left and right valve body 1,2, combustion gas controlling organization 4, gas ignition mechanism 5, blast tube 6, nozzle 7; The shifting block 8 of gas ignition mechanism 5 is arranged on the spool 9 of combustion gas controlling organization 4, can control gas ignition mechanism 5 simultaneously by control combustion gas controlling organization 4 lights a fire, and control the open and close and the channel sized of blast tube 6 simultaneously, realize the Synchronization Control of combustion gas controlling organization 4 and gas ignition mechanism 5.
Combustion gas controlling organization 4 comprises rotating shaft 10, with the spool 9 that is connected with rotating shaft 10, wherein spool 9 is threaded with valve body 3, make spool 9 can be in valve body 3 move left and right, tail end at spool 9 is fastened with seal spool head 11, the other end of seal spool head 11 can when rotating shaft 10 drive spools 9 are moved to the left, also just drive the nozzle bore 12 that seal spool head 11 is opened nozzle 7 with nozzle 7 sealings in valve body 3.
Blast tube 6 comprises the hole 16 that clearance channel 14 between air inlet pipe 13, spool 9 and the valve body 3, air inlet pipe 13 communicate with spool bore 15 in the spool 9, hole 17, the nozzle bore 12 that spool bore 15 communicates with clearance channel 14.The combustion gas of air inlet pipe 13 can be from the hole 16 enters spool bore 15, enters clearance channel 14 by hole 17, at last from nozzle bore 12 ejections.In spool 9, be provided with needle 18, be stuck in the spool 9 by flexible member 19, needle 18 can block combustion gas and 16 enter spool bore 15 from the hole, when pressing 9 rotations of lower rotary shaft 10 drive spools, flexible member 19 can drive needle 18 and open the hole 15 that air inlet pipe 13 communicates with spool bore 15 in the spool 9, make combustion gas 16 enter spool bore 15, enter nozzle bore 12 from the hole, thus the open and close and the channel sized of the combustion gas in the control blast tube 6.
Gas ignition mechanism 5 comprises shifting block 8, piezoelectric ceramics 21, electronic card 22, hammer 23, the spring 24 on the spool 9 that is arranged on combustion gas controlling organization 4, after rotating shaft 10 drives spool 9 rotations, shifting block 8 can be stirred hammer 23 away from piezoelectric ceramics 21, after hammer 23 breaks away from shifting block 8, under the effect of spring 24, reset rapidly, and bump piezoelectric ceramics 21, produce the spark ignition combustion gas, so can control the igniting of gas ignition mechanism 5 simultaneously by rotating shaft 10.
The rear end of seal spool head 11 is fastened in the spool bore 15 of spool 9, and front end is a sharp cone distal 25, and 25 of sharp cone distal are plugged in the nozzle bore 12, with nozzle 7 sealings.
