Abstract
The utility model relates to a valve for a gas fuel water heater, which is free from explosion and is safe as well as environment-protecting. The valve for a gas fuel water heater comprises a valve body and an electromagnetic valve. The valve for a gas fuel water heater is characterized in that the valve body is provided with two communicated valve chambers, and each valve chamber is respectively provided with the electromagnetic valve; passages controlled by the two electromagnetic valves are connected in parallel; the flux of the two electromagnetic valves are different. When a gas water heater is ignited, users can turn on the electromagnetic valve which has a smaller flux at first so as to cause the gas quantity of a fire discharging outlet to be smaller; as a consequence, explosion can be prevented; after the successful ignition, the other electromagnetic valve can be turned on so as to ensure the flux of the valve for a gas fuel water heater.
Description
Technical field
The utility model relates to a kind of gas water-heater valve.
Background technique
Existing gas water-heater comprises valve body and solenoid valve with valve; Valve body is provided with gas-entered passageway and outlet passageway, is provided with valve pocket between gas-entered passageway and the outlet passageway, and gas-entered passageway, valve pocket and outlet passageway constitute blast tube, and wherein outlet passageway communicates with burning fire row; Solenoid valve comprises coil, spool, spring, stuffing box gland and sealing valve glue, the stuffing box gland of solenoid valve is sealed the port of the valve pocket of valve body, its sealing valve glue is positioned at valve pocket and links to each other with spool, and during normality, spring will seal the outlet passageway of spool top on valve body, gas-entered passageway does not communicate with outlet passageway, valve is in closed condition, after the electromagnetic coil energising, and spool pull-up sealing valve glue, gas-entered passageway is communicated with outlet passageway, and valve is in open mode; This gas water-heater is mainly used on the full-automatic gas-fired water heater with valve, its principle is that after the gas water-heater water flowing, controller warms oneself in front of a fire earlier to arrange and sends pulse igniting, and then connect gas water-heater with the electromagnetic coil on the valve, combustion gas through gas water-heater with the valve row's air feed that warms oneself in front of a fire; Its shortcoming is that ignition point produces that combustion gas that detonation promptly accumulates in fire row mouthful is one by one lighted suddenly and burning that quick-fried sound takes place; More seriously, it is bad when in case the igniting pin is caused the ignition function fashion by dust pollution, behind loss of ignition several times, accumulate in inflammable gas in the water heater in a large number to external diffusion, if the user on and on repays the pilot fire, in a single day successfully will blast and light a fire, if igniting is unsuccessful, cause environmental pollution in then a large amount of harmful combustion gas discharging air, so also have poor stability, problem of environment pollution caused.
Summary of the invention
The purpose of this utility model is to produce the problem of detonation, poor stability in order to solve existing gas water-heater with the water heater ignition point that exists in the valve, and a kind of new gas water-heater valve is provided.
Technological scheme:
The purpose of this utility model is achieved in that a kind of gas water-heater valve, comprises valve body and solenoid valve, it is characterized in that valve body is provided with two valve pockets that communicate, and each valve pocket is equipped with solenoid valve respectively, two passage parallel connections that solenoid valve is controlled.Gas water-heater when igniting, at first open one of them solenoid valve, make ignition point, fire row's mouthful gas quantity is less, thereby can not cause detonation, another solenoid valve is opened after light a fire successfully again, uses the flow of valve with the assurance gas water-heater.
Described gas water-heater valve is characterized in that the flow of described two electromagnetic valve is inequality.During the gas water-heater igniting, at first open the wherein less solenoid valve of flow, make ignition point, the gas quantity of fire row mouth is less, again another solenoid valve is opened after lighting a fire successfully, to guarantee the flow of gas water-heater with valve, enter normal operating condition after, the less solenoid valve of flow can cut out, and also can not close.
Beneficial effect:
Owing to adopted technological scheme described in the utility model, effectively detonation can not take place during igniting in the gas quantity of control ignition moment fire row mouth; It is bad when even the igniting pin is caused the ignition function fashion by dust pollution, the inflammable gas that accumulates in the water heater behind loss of ignition several times can be not too many yet, reduced the release of harmful combustion gas, compared with valve, reduced the pollution of harmful combustion gas environment with existing gas water-heater.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Shown in the accompanying drawing structural representation of gas water-heater described in the utility model with an embodiment of valve.
Among the figure 1, valve body, 101, gas-entered passageway, 102, outlet passageway, 103, main valve chamber, 104, secondary valve pocket, 105, primary valve, 106, secondary valve port, 107, connecting passage, 2, the main valve coil, 201, main valve glue, 202, main valve plug, 203, the primary seal cover, 3, secondary valve coil, 301, secondary valve glue, 302, auxiliary valve core, 303, secondary stuffing box gland.
Embodiment:
Shown in the accompanying drawing embodiment of gas water-heater described in the utility model with valve, as seen from the figure, described gas water-heater valve, comprise valve body 1, main electromagnetic valve and secondary solenoid valve, valve body 1 is provided with main valve chamber 103 and secondary valve pocket 104, connecting passage 107 is communicated with main valve chamber and secondary valve pocket, main electromagnetic valve is housed on the main valve chamber, on the secondary valve pocket secondary solenoid valve is housed, main electromagnetic valve is by main coil 2, main valve plug 202, main valve glue 201 and primary seal cover 203 constitute, secondary solenoid valve is by secondary coil 3, auxiliary valve core 302, secondary valve glue 301 and secondary stuffing box gland 303 constitute, the passage that main electromagnetic valve is controlled is in parallel with the passage of secondary electromagnetic valve, and primary valve 105 is greater than secondary valve port 106.
Claims (2)
1, a kind of gas water-heater valve comprises valve body and solenoid valve, it is characterized in that valve body is provided with two valve pockets that communicate, and each valve pocket is equipped with solenoid valve respectively, two passage parallel connections that solenoid valve is controlled.
2, according to the described gas water-heater valve of claim 1, it is characterized in that the flow of described two electromagnetic valve is inequality.
