Description

The dual gas supply stopcock
Technical field
The utility model relates to a kind of gas appliance, as gas roastor, gas range etc., the essential parts of especially a kind of double-source gas apparatus, specifically a kind of dual gas supply stopcock.
Background technique
As everyone knows, general gas appliance such as gas roastor, the source of the gas that kitchen range etc. are commonly used has rock gas and liquefied petroleum gas (LPG), because the calorific value difference of two kinds of combustion gas, its nozzle arrangements is also different during therefore concrete the use, existing for this reason gas appliance can use rock gas can use liquefied petroleum gas (LPG) again in order to make same apparatus, all improve at aspects such as reduction valve and nozzles, designed double-air-supply nozzle, under the situation of correct connection source of the gas, can satisfy usage requirement basically, method commonly used is to realize the selection and the use of source of the gas by changing valve and control valve on air feed is selected, if but select wrong source of the gas with changing valve, then may easily produce fire because flame is too high, exist hidden danger is installed, structurally also seem comparatively complicated simultaneously.Therefore be badly in need of a kind of stopcock that is installed on the dual gas supply gas circuit of design, make gas appliance can only be operated under the selected source of the gas state, if promptly the work source of the gas of She Dinging is a rock gas, then this valve can only pass through rock gas after being threaded to rock gas, the liquefied petroleum gas (LPG) suction port is closed automatically, and vice versa.And according to the knowledge of the applicant, it is available still not have Related product at present.
Summary of the invention
The purpose of this utility model is a problem of being badly in need of a kind of safe way valve at the double-source gas apparatus, designs a kind of dual gas supply stopcock.
The technical solution of the utility model is:
A kind of dual gas supply stopcock, mainly comprise valve body 1, valve gap 2, upper valve rod 3 and spool 4, valve gap 2 is installed on the valve body 1, spool 4 during upper valve rod 3 passes valve gap 2 and is installed in valve body 1 links to each other, and it is characterized in that described valve body 1 is provided with gas inlet 5 and liquid gas inlet 6 and gas outlet 7 and the liquid gas outlet 8 that all communicates with valve pocket; Described spool 4 is provided with the arc convex section 9 that is used to stop up gas inlet 5 or liquid gas inlet 6, main center at spool 4 has air outlet hole 10, have the air outlet channel 11 that communicates with air outlet hole 10 on the main wall of spool 4, gas outlet 7 on this air outlet channel 11 and the valve body 1 or liquid gas outlet 8 communicate.
In the described valve body 1 solenoid valve 12 is installed, the upper end step face of solenoid valve 12 and the entrance point of the air outlet hole 10 on the spool 4 offset; Described upper valve rod 3 is connected with lower valve rod 13, and an end of lower valve rod 13 passes spool 4 and offsets with solenoid valve 12, also is set with spring 14 on lower valve rod 13.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment one.
As Fig. 1,2,3,4.
A kind of dual gas supply stopcock, mainly comprise valve body 1, valve gap 2, upper valve rod 3 and spool 4, valve gap 2 is installed on the valve body 1, spool 4 during upper valve rod 3 passes valve gap 2 and is installed in valve body 1 links to each other, as shown in Figure 1, 2, valve body 1 is provided with gas inlet 5 and liquid gas inlet 6 and gas outlet 7 and the liquid gas outlet 8 that all communicates with valve pocket; Described spool 4 is provided with the arc convex section 9 that is used to stop up gas inlet 5 or liquid gas inlet 6, main center at spool 4 has air outlet hole 10, on the main wall of spool 4, have the air outlet channel 11 that communicates with air outlet hole 10, gas outlet 7 on this air outlet channel 11 and the valve body 1 or liquid gas outlet 8 communicate, as shown in Figure 3.Solenoid valve 12 is installed in valve body 1, and the upper end step face of solenoid valve 12 and the entrance point of the air outlet hole 10 on the spool 4 offset; Described upper valve rod 3 is connected with lower valve rod 13, and an end of lower valve rod 13 passes spool 4 and offsets with solenoid valve 12, also is set with spring 14 on lower valve rod 13.Between the entrance point of the upper end step face of solenoid valve 12 and the air outlet hole 10 on the spool 4, sealing gasket 15 is installed.
The working principle of present embodiment is:
As shown in Figure 4, after two kinds of sources of the gas pass through corresponding pressure maintaining valve respectively, corresponding inlet from stopcock 19 of the present utility model inserts respectively, two kinds of gas outlets on the valve body are connected with corresponding inlet on the double-air-supply nozzle 17 respectively, solenoid valve 12 in the valve body is connected with thermocouple 16, the induction end of thermocouple 16 places burner 18 next doors, and the flame that produces when burner 18 work can touch the induction end of thermocouple 16, thereby makes thermocouple 16 produce certain electromotive force.
After gas circuit and circuit connect, if use rock gas, then upper valve rod 3 is put to turn to putting fire screen along rock gas, during turn, upper valve rod 3 drives spools 4 turns, when some fire screen, spool 4 can be closed liquefied petroleum gas (LPG) (LP) inlet 6, makes 5 conductings of rock gas (NG) inlet, simultaneously, air outlet channel 11 on the spool 4 communicates with rock gas NG outlet 7, and liquefied petroleum gas (LPG) LP outlet 8 is closed.At this moment, press upper valve rod 3 and maintenance, upper valve rod 3 can be depressed solenoid valve 12 by lower valve rod 13, the conducting of whole rock gas gas circuit.Igniting can make burner 18 burnings, makes thermocouple 16 produce electromotive force during burning.The electric current that produces can make solenoid valve 12 adhesives.If unclamp hand this time, entire machine can keep working state, if want to change the firepower size of burner 18, can follow turn upper valve rod 3, thereby the contact ratio of air outlet hole 10 on the drive spool 4 and the gas outlet 7 on the ports valve body 1 changes the size of gas circuit air-flow.
After gas circuit and circuit connect, if use liquid gas (LP), then with upper valve rod 3 along the turn of LP direction to putting fire screen, during turn, upper valve rod 3 drives spool 4 turns, when some fire screen, spool 4 can be closed NG inlet 5, just LP 6 conductings that enter the mouth, simultaneously, air outlet hole 10,11 on the spool 4 communicates with LP outlet 8, and NG outlet 7 is closed, and operating process is the same.
If run into fortuitous event burner 18 is extinguished; then thermocouple 16 no longer produces electromotive force, and solenoid valve 12 can be thrown off because of losing electric current, and the epithelium of solenoid valve 12 terminations (sealing gasket 15) can be closed whole gas circuit; combustion gas is not leaked, play the effect of " blowout protection ".
Embodiment two.
Shown in Fig. 1,2,3,5.
Present embodiment and embodiment's one difference are solenoid valve 12 is not installed in the valve body 1, and thermocouple is not installed near burner during use yet, correspondingly also do not have extinguish protection function, but its structure are simple relatively, and cost is lower, and all the other and embodiment one are identical.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
