Description

Structure improved gas heater burner's gas-separating valve
Technical field:
The utility model relates to gas water-heater, relates in particular to burner gas-separating valve device in the gas water-heater.
Background technique:
Early stage gas water-heater is to be made of critical pieces such as aqueous vapor interstage valve, burner, heat exchangers, the output of the combustion power of burner mainly is that the adjusting by aqueous vapor interstage valve gas valve core realizes, the output of combustion power changes and is subjected to great limitation; Therefore, after 2000, people work out a kind of burner gas-separating valve that can realize two sections combustion gas outputs, make the combustion power output variation of burner that improvement arranged; The combustion gas output of described this kind burner gas-separating valve is divided into two sections, and one section is full power output, and another section is half of full power output.This kind burner gas-separating valve, as shown in Figure 1, by valve seat 101, valve gap 102, rotating shaft 103, spring 104, rubber stopper 105, and seal washer 106 major parts such as grade are formed; Its working principle is: valve seat 101 bottoms are provided with suction port 100, and valve seat 101 and valve gap 102 are formed a blast tube 107, and this blast tube is divided into two sections, and the rotation of rotating shaft 103 has two gears; When rotating shaft 103 during in first position, rely on the pressure of spring 104, make rubber stopper 105 with 108 sealings of blast tube 107 epimere suction ports, at this moment, combustion gas can only be passed through blast tube 107 hypomere passages, and half burning zone burning of supplied burner has realized half-power output; When rotating shaft 103 rotates to the another location, rotating shaft 103 is raised, rubber stopper 105 moves with rotating shaft 103, thereby blast tube epimere suction port 108 is opened, at this moment, combustion gas is the blowing mouth 109 by blast tube 107 epimere passages simultaneously, second half burning zone burning of supplied burner, the burner combustion section is all burnt, and has realized full power output.
Though this kind burner gas-separating valve makes burner realize dividing the operating mode of two sections burnings, the gas water-heater of being installed still exists the phenomenon of the too hot inconvenient shower of adjustable hot water in summer, and, the waste combustion gas; In addition, this kind burner gas-separating valve also exists such as adjusting knob and moves more problems such as up and down because of rotating shaft 103 often, the inconvenience that causes people to use.
Summary of the invention:
At the technical deficiency of the existing two sections combustion gas output of gas water-heater burner gas-separating valve, the purpose of this utility model is to provide a kind of structure improved gas heater burner's gas-separating valve; Described burner gas-separating valve by structure improvement, can divide three sections or multistage to do combustion gas output to the burner of configuration, so that described gas water-heater is when using summer, conveniently regulates water temperature, and economizes on gas; Simultaneously, by structure improvement, described burner gas-separating valve is simple and reliable for structure, good stability.
For achieving the above object, the utility model adopts following design proposal when for three sections depressed structures of branch:
