Abstract

The utility model relates to a safety valve for a gas range. The utility model is composed of a valve body, a push rod, an electromagnetic valve, a thermocouple, a timer, etc. The thermocouple is fixed above the flame of the gas range. The electromagnetic valve is controlled by the temperature change of the thermocouple to open and close in order to make the chuck of the electromagnetic valve open or close the gas hole of the valve body. The utility model has the advantages that when gas is extinguished accidentally, the safety valve for a gas range can automatically close in order to prevent the gas from leaking out. The utility model guarantees the safety of people's lives and property.

Description

Safety valve for gas range

The utility model relates to a kind of gas-cooker safety valve.

When the fuel gas of burning is extinguished because of contingency, the function that general gas-cooker valve is not closed automatically, the personnel that often cause poison or cause and cause heavy losses to the people's lives and property by fire.

But the gas-cooker safety valve of automatic-closing valve when the purpose of this utility model is to provide a kind of combustion gas to be extinguished.

Gas-cooker safety valve of the present utility model comprises valve body, push rod, timer, magnetic valve and thermocouple, valve body is by forming with the inlet chamber of pipeline connection and the discharge chamber that is communicated with cooking stove, described magnetic valve is installed in the inlet chamber of valve body, the sucker on its motion bar top is under spring action, pore between valve body inlet chamber and the outlet chamber can be sealed, described push rod is installed in the outlet chamber of valve body, the one end withstands on the sucker of magnetic valve, the other end stretches out outside the valve body, be wound with back-moving spring on the push rod, described timer is installed in the valve body outside, the cam of timer drives push rod, depress the sucker of magnetic valve, described thermocouple is fixed on cooking stove flame top, and magnetic valve is controlled break-make by thermocouple.During use, rotate timer knob, make its cam drive the push rod motion, push rod overcomes the elastic force of back-moving spring in the magnetic valve depresses sucker, and valve body inlet and outlet chamber is communicated with, and combustion gas can enter discharge chamber by inlet chamber, enter cooking stove again, after cooking stove was lighted, thermocouple was heated, and made the magnetic valve energising, electromagnet firmly holds sucker, keep pore open-minded, timer then automatically reset in one minute, and push rod sets back under action of reset spring.If combustion gas is extinguished, thermocouple turns cold, the magnetic valve outage, and sucker moves upward under spring action the pore sealing, and combustion gas no longer leaks outside.

The utility model has the advantages that the gas-cooker valve can be closed automatically when combustion gas is extinguished by accident, thereby guaranteed the safety of people's life and property.

Fig. 1 is a structural representation of the present utility model.

Embodiment: referring to Fig. 1, the utility model is by valve body 3, push rod 4, magnetic valve 8, thermocouple 9 and timer 1 are formed, valve body 3 is made up of inlet chamber and discharge chamber two parts, inlet chamber is communicated with fuel gas pipeline by connecing mouth, discharge chamber then is communicated with cooking stove by connecing mouth and sebific duct, magnetic valve 8 is installed in the inlet chamber of valve body 3, when magnetic valve cuts off the power supply, under the effect of spring 7, sucker 6 is with the inlet chamber and the sealing of the pore between the discharge chamber of valve body 3, push rod 4 is installed in the discharge chamber of valve body 3, the one end withstands on the sucker 6 of magnetic valve 8, the other end stretches out valve body 3 outsides, be wound with back-moving spring 5 on the push rod 4, timer 1 is installed in valve body 3 outsides, the cam 2 of timer 1 is pressed in the end that push rod 4 stretches out valve body 3, knob 10 can drive the cam 2 that is fixed in the rotating shaft, push rod 4 is depressed, push rod 4 promotes sucker 6 again and moves downward, pore between inlet chamber and the discharge chamber is opened, the time that timer 1 limits is 1-2 minute, after the cam 2 of timer 1 resetted, push rod 4 moved upward under the effect of back-moving spring 5, contacted with cam 2 profiles all the time, the break-make of magnetic valve 8 is by thermocouple 9 controls, thermocouple 9 is fixed on cooking stove flame top, after thermocouple 9 is heated, and magnetic valve 8 energisings, sucker 6 is inhaled down, pore is opened, after combustion gas is extinguished, when thermocouple 9 is reduced to uniform temperature, magnetic valve 8 outages, sucker 6 seals pore under spring 7 effects.If in the inlet chamber of valve body 3 and discharge chamber two magnetic valves 8 and two push rods 4 are installed respectively, then a valve can be controlled two cooking stoves.

Claims

1, a kind of gas-cooker safety-valve, it is characterized in that comprising valve body 3, push rod 4, magnetic valve 8, thermocouple 9 and timer 1, described valve body 3 is made up of the inlet chamber that is communicated with gas pipeline and discharge chamber two parts of being communicated with cooking stove, described magnetic valve 8 is installed in the inlet chamber of valve body 3, the sucker 6 on its motion bar top can seal the pore between valve body 3 inlet chambers and the discharge chamber under spring 7 effects, described push rod 4 is installed in the discharge chamber of valve body 3, push rod 4 one ends withstand on the sucker 6, its other end stretches out valve body 3, be wound with back-moving spring 5 on the push rod 4, described timer 1 is installed in valve body 3 outsides, the cam 2 of timer 1 drives the sucker 6 that push rod 4 is depressed magnetic valve 8, described thermocouple 9 is fixed on cooking stove flame top, and the break-make of magnetic valve 8 is by thermocouple 9 controls.

2, gas-cooker safety valve according to claim 1 is characterized in that in described valve body 3 inlet chambers two magnetic valves 8 being installed, and two push rods 4 supporting with two magnetic valves 8 are installed in its discharge chamber respectively.
