Abstract
The utility model relates to a gas source alarm used for preventing the gas leakage before entering a gas stove, etc. The utility model comprises a gas regulating valve 1, a pressure regulating device 2, a buzzer 13, a power supply, etc. The utility model is characterized in that the central position of a gas cushion 8 in the cavity of the pressure regulating device 2 is provided with a push rod 10 which passes through the center of the gas locker 9 of the pressure regulating mouth of the pressure regulating device, and two metal reeds 11, 12 are arranged above the push rod 10, the reeds 11, 12, the buzzer 13, and the power supply are connected in series. The structure of the utility model is simple, and the utility model is a reliable safety alarm device for the gas stove.
Description
The utility model relates to a kind of and the matching used source of the gas warning device of gas furnace.
At present, when using gas furnace,, so just easily cause combustion gas in the process of gas furnace, leaking, easily cause danger, occur accident because the forgeing of people, faulty operation etc. make fuel gas source be easy to be in the gas source valve open mode.
The purpose of this utility model is to provide a kind of energy reminds people in time to turn off the fuel gas source alarm of gas source valve after using combustion gas.
Scheme of the present utility model is as follows: it comprises Air-regulating valves 1, pressure regulator 2 and hummer 13, its architectural feature is: Air-regulating valves 1 is to be fixed with rotary switch 4 on the following square nut 16 of the source of the gas knob 3 of fuel gas source Air-regulating valves, the inwall of the lower end of rotary switch 4 is corresponding to the side outer wall shape of nut 16 so that rotary switch 4 fastening on nut 16, simultaneously, rotary switch 4 can be shifted one's position on nut 16, each is fixed with a metallic conduction sheet 6 and 5 respectively on the lateral wall on the madial wall of source of the gas knob 3 and rotary switch 4 tops, when the source of the gas knob is opened, metallic conduction sheet 6 and 5 is in contact with one another, after source of the gas knob 3 is closed, metallic conduction sheet 6 and 5 disconnects simultaneously, and the gas outlet of Air-regulating valves 1 is connected by knob 15 with the fuel gas inlet of pressure regulator 2.Pressure regulator is made up of shell, air cushion 8, vent plug 9, push rod 10, the top that air cushion 8 is positioned at pressure regulator chamber air intake opening separates the pressure regulator cavity up and down, push rod 10 passes the center of vent plug 9 and is fixed on the air cushion center, above push rod, turn the shape support by one and be fixed with two metal spring leafs 11 and 12, reed switch respectively with power supply, hummer 13 and gas
Conducting strip 6 on knob and the rotary switch and 5 series electrical connect.
The utility model is simple in structure, and is easy to use, is the reliable safety alarm device of gas furnace.
Fig. 1 is a structural representation of the present utility model.
Air-regulating valves 1 is to be fixed with rotary switch 4 on the following square nut 16 of the source of the gas knob 3 of fuel gas source Air-regulating valves among Fig. 1, the lower end inwall of rotary switch 4 is the side outer wall shape corresponding to nut 16, so that rotary switch fastening on nut 16, simultaneously, rotary switch can also be in nut 16 up conversion positions, respectively be fixed with a metallic conduction sheet 6 and 5 respectively at the madial wall of source of the gas knob and the lateral wall on rotary switch top, metallic conduction sheet 6 links to each other with the conductive jack 7 that is fixed on the rotary switch lower end respectively with 5, when the source of the gas knob is opened, metallic conduction sheet 6 and 5 is in contact with one another, after the source of the gas knob was closed, metallic conduction sheet 6 and 5 disconnected simultaneously.The gas outlet of Air-regulating valves 1 connects by knob 15 activities with the fuel gas inlet of pressure regulator 2, with the matching used pressure regulator of gas furnace 2 chambeies in air intake opening above, by air cushion 8 the pressure regulator cavity is separated up and down, the outlet of pressure regulator is linked to each other with gas furnace by snorkel.The feature of pressure regulator 2 is to be fixed with a push rod 10 in air cushion 8 centers, push rod 10 passes the center of the vent plug in the mouth 9 on the pressure regulator and stretches out outside the pressure regulator, the top of push rod 10 is turned the shape support and is fixed on two parallel placed metal reeds 11 and 12, reed 11 and 12 has at interval, reed 12 electrically connects with power supply, hummer string shape, and another terminal of the lead-in wire of reed 11 and hummer is connected on the jack 7.When opening source of the gas knob 3, even conducting strip 6 and 5 is in on-state simultaneously, at this moment, combustion gas is entered in the pressure regulator by Air-regulating valves, if do not open gas stove switch, because pressure regulator lower chamber internal gas pressure increases, and air cushion 8 is bulged, air cushion 8 upwards pushes reed 11, reed 11 and 12 is in contact with one another, power connection then, hummer begin to report to the police, and turn off the source of the gas knob with prompting, after gas stove switch is opened, combustion gas can not form than hyperbar in the pressure regulator lower chamber owing to entered the gas furnace burning, and hummer can not reported to the police.
