Abstract
The utility model which discloses an aqueous vapor linkage valve body of a gas water heater comprises a valve shell body, and a gas path which is communicated with a main burner, an aqueous vapor linkage device and a microswitch which is connected with the aqueous vapor linkage device are arranged in the shell body, and an electromagnetic valve is arranged in the gas path of the shell body, and the utility model is characterized in that a small gas path which is arranged in the shell is provided with the electromagnetic valve and is communicated with a small burner in a combustion chamber. The aqueous vapor linkage valve body of a gas water heater of the utility model has the advantages of timely and safe ignition and no burning explosion, and is the perfect aqueous vapor linkage valve body in present gas water heaters.
Description
The utility model relates to a kind of valve means, specifically relates to a kind of aqueous vapor linkage valve of gas heater.
The aqueous vapor linkage valve of the gas heater of known technology generally comprises valve chest, be provided with a gas circuit that communicates with main burner and aqueous vapor linkage in the housing, in the gas circuit of housing, be provided with a magnetic valve, when opening water valve, in the combustion chamber, fill combustion gas, the ignition switch sparking.The shortcoming of said structure is, owing to fill combustion gas earlier, lights a fire again in the combustion chamber, and meeting appearance point ignition delay, thus easily produce the phenomenon of " firing ", simultaneously also dangerous.
The purpose of this utility model is to provide a kind of water and gas coupled valve of gas water heater body of lighting a fire timely and safe.
For achieving the above object, the utility model adopts following scheme to realize: this aqueous vapor linkage valve is made of valve chest, be provided with a gas circuit that communicates with main burner and aqueous vapor linkage in the housing, in this gas circuit, be provided with a magnetic valve, it is characterized in that, also be provided with a little gas circuit in the housing, also be provided with a magnetic valve on the gas circuit, small fire burner set in this gas circuit and the combustion chamber is connected.
After adopting said structure, owing to also be provided with a little gas circuit in housing, small fire burner set in this gas circuit and the combustion chamber is connected, therefore, opening inlet valve, behind the starting aqueous vapor linkage, igniting needle to the sparking of small fire burner place, is opened the magnetic valve on the little gas circuit earlier again, light little fire, just start main gas path device after little fire is lighted,, more safety problem can not occur so " firing " phenomenon can not occur.
Be described further below in conjunction with drawings and Examples.
Fig. 1 is the utility model broken section structural representation;
Fig. 2 is the structural representation of the utility model band burner;
Fig. 3 is the utility model fundamental diagram.
As shown in Figure 1 and Figure 2, the utility model aqueous vapor linkage valve is made of valve chest 1, be provided with gas circuit 8, a stingy road 7 that links to each other with small fire burner 6 and an aqueous vapor linkage 2 that communicates with main burner 5 in the housing 1, in the gas circuit of housing 1, be equipped with a magnetic valve 3,4, be provided with water inlet pipe and water outlet pipe 9,10 in the housing, also be provided with the microswitch 11 that links to each other with the aqueous vapor linkage on the housing.
As shown in Figure 3, operation principle operating process of the present utility model is such: at first open inlet valve, behind the starting aqueous vapor linkage 2, igniting needle is struck sparks to small fire burner 6 places earlier, open the magnetic valve 4 on the stingy road 7 again, light little fire, (unignited little fire should shut down in 7 seconds); Confirm to open magnetic valve 3 again after little fire is lighted, light main fire.Then can not opens solenoid valve 3 if little fire is unignited, if continuous 7 seconds unignited little fire, then water valve is reset in shutdown; After confirming that main fire is lighted, close little fire, should repeat above-mentioned action automatically if main fire extinguishes (water valve is still when work).So, " firing " phenomenon can not occur, more safety problem can not occur.
