The utility model has the advantages of simple structure, easy manufacture and low cost; the utility model combines a gas passage with small load amounta and a gas passage with large load amounts to share one gas passage, which completely achieves double effects of energy saving and security.
Description
Technical field
The utility model relates to a kind of differential aqueous vapor interstage valve assembly that is used for gas heater, more particularly belongs to the improvement technology of aqueous vapor interstage valve assembly.
Background technology
At present, water and gas coupled valve of gas water heater adopts the water heater air-channel system of buffering igniting, anti-detonation more.Chinese patent " water and gas coupled valve of gas water heater body ", the patent No.: 02225039.5, this utility model discloses a kind of water and gas coupled valve of gas water heater body that is made of valve chest, be provided with gas circuit and an aqueous vapor linkage and the microswitch that links to each other with the aqueous vapor linkage that communicates with main burner in the housing, in the gas circuit of housing, be provided with a magnetic valve, it is characterized in that, also be provided with a little gas circuit in the housing, gas circuit is provided with magnetic valve, and small fire burner set in this gas circuit and the combustion chamber is connected.Adopt the water and gas coupled valve of gas water heater body of said structure to have the timely and safe advantage of igniting, " firing " phenomenon can not occur.It is the more satisfactory aqueous vapor linkage valve of present gas heater.And Chinese patent " a kind of anti-explosion gas water heater controller for gas ", the patent No.: 01256061.8, a kind of explosion-proof control device of gas heater is provided, it comprises: small fire burner, main burner, gas valve body, air valve, water valve, water-control switch, the aqueous vapor interstage valve, the nozzle distributing pipe, ignitor, the signal feedback device, main solenoid valve, little thermoelectricity magnet valve, intelligent controller, wherein gas valve body comprises little fiery gas valve and main gas valve and fuel gas inlet hole, be provided with little fiery combustion gas through hole between the two, intelligent controller can be after receiving small fire burner normal combustion feedback signal, the igniting of instruction main burner, after receiving the undesired signal of small fire burner or main burner, instruct little thermoelectricity magnet valve and main solenoid valve to close.But the little gas circuit of this type of aqueous vapor interstage valve does not have double insurance without the valve of interstage valve, has certain potential safety hazard.Service life of battery has been shortened in also long-term work of little magnetic valve simultaneously (the power supply power consumption is big) greatly, is unfavorable for environmental protection.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiency of prior art and a kind of simple in structure, working stability, security performance height, the water and gas coupled valve of gas water heater of long service life are provided.
The utility model can take following technical measures to solve: the explosion-proof aqueous vapor interstage valve of a kind of gas heater includes valve body 1, main solenoid valve 2, sealing ring A3, interstage valve 4, water valve body 5, microswitch assembly 6, secondary magnetic valve 7, sealing ring B8.Wherein main solenoid valve 2 and secondary magnetic valve 7 are packed on the valve body 1, and the left end of the right-hand member of valve body 1 and interstage valve 4 is solidly installed, and microswitch assembly 6 is packed in the end of keeping right of interstage valve 4, and the left end of the right-hand member of interstage valve 4 and water valve body 5 is solidly installed.Its structural feature is: main solenoid valve 2 and secondary magnetic valve 7 shared blast tubes 14, little load combustion gas and big load combustion gas are with firing in burner 9.
Outstanding effect of the present utility model is:
1), of the present utility model simple in structure, make easily;
2), cost of the present utility model is low, merged little load blast tube and the big shared blast tube 14 of load blast tube, reaches the effect of double insurance fully;
3), the utility model finishes and starts the operating voltage of in time cutting off secondary magnetic valve 7 after the course of work, can reach energy-saving effect.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment 1
Be elaborated below in conjunction with the utility model structural representation, as shown in Figure 1,
The explosion-proof aqueous vapor interstage valve of a kind of gas heater includes valve body 1, main solenoid valve 2, sealing ring A3, interstage valve 4, water valve body 5, microswitch assembly 6, secondary magnetic valve 7, sealing ring B8.Wherein main solenoid valve 2 and secondary magnetic valve 7 are packed on the valve body 1 successively, and the left end of the right-hand member of valve body 1 and interstage valve 4 is solidly installed, and microswitch assembly 6 is packed in the end of keeping right of interstage valve 4, and the left end of the right-hand member of interstage valve 4 and water valve body 5 is solidly installed.Main solenoid valve 2 and secondary magnetic valve 7 shared blast tubes 14, little load combustion gas and big load combustion gas are with firing in burner 9.
Operation principle: when using the utility model, differential aqueous vapor interstage valve is contained on the water heater that uses combustion gas, by with the supporting use of burner, form the gas circuit and the combustion control system 13 of water heater.There are the current of certain pressure fashionable at water valve body 5 water inlets, promotion is connected the valve between interstage valve 4 and the water valve body 5, with also opening microswitch assembly 6, controller 13 gets the high-tension ignition of electric afterpulse formula, behind the delayed firing 0.5 second, secondary magnetic valve 7 is opened, and combustion gas enters in the burner 9 through the valve that the little load of minor valve enters air valve body and interstage valve 4 again, and generation was burnt when 11 high-tension ignition spark moments of igniting pin on combustion gas and the controller 13 contacts.After the flame probe 10 of controller 13 detected flare up fire, time-delay 1-2 opened main solenoid valve 2 second again, and the valve that enters air valve body and interstage valve 4 by big valve full load amount increase combustion gas enters burner 9 burnings more again.The 0.5-1 that delays time simultaneously can cut off the operating voltage of secondary magnetic valve 7 after second, continue to provide combustion gas to burner 9 burnings by the valve full load amount of main solenoid valve 2, and heat is by heat exchanger 12 heat conduction water routes.(finish the operating voltage of in time cutting off secondary magnetic valve 7 after the above-mentioned course of work, can reach energy-saving effect).The air-path control system of this structure is to utilize same gas circuit and will reach the effect of double insurance fully through the valve of interstage valve 4 to burner.
