Abstract

The gas automatic gas closing valve is a timing automatic gas closing valve which can timely and automatically close the fire source according to the needs of the fire use time, which is used for the gas cooker. It includes a solenoid valve, a timing circuit module is connected to the solenoid valve, and a battery box, a timing switch and an adjusting knob are arranged on the timing circuit module. After ignition, set the fire use time by adjusting the knob and timing switch. When the time is up, the timing circuit module controls the solenoid valve to turn off the gas source, so that the stove fire is extinguished, so as to achieve the purpose of automatically turning off the fire at a fixed time, and avoid forgetting to turn off the fire resulting losses.

Description

Gas automatic shut-off valve

technical field

The utility model relates to an automatic device for regularly closing gas, in particular to a gas automatic closing valve for a gas stove.

Background technique

Existing gas ranges generally have the function of electronic ignition, and some more advanced gas ranges on the market also have the function of automatically shutting off the gas and extinguishing the fire in case of accident (when the soup overflows to extinguish the range fire). However, in the absence of the above accidents, if the fire is used for a long time and the fire is forgotten to be turned off, the stove will be burned out, and an accident may occur.

Contents of the invention

The purpose of the utility model is to provide a gas automatic shut-off valve for a gas cooker, which can timely and automatically shut off the fire source according to the needs of the fire use time.

In order to achieve the above purpose, the technical solution adopted by the utility model is: the gas automatic gas shut-off valve includes a solenoid valve, a timing circuit module is connected to the solenoid valve, and a battery box and an adjustment device are arranged on the timing circuit module.

The adjusting device is a timing switch and an adjusting knob arranged on the timing circuit module.

The timing circuit module is respectively connected with the solenoid valve and the battery box through wires.

Since the electromagnetic valve is arranged before the air inlet of the gas stove, and the fire time is set in advance through the adjusting knob and the timing switch, when the time is reached, the timing circuit module controls the electromagnetic valve to close the gas source, so that the stove fire is extinguished, thereby achieving The purpose of automatically turning off the fire at regular intervals is to avoid losses caused by forgetting to turn off the fire.

Description of drawings

Fig. 1 is a structural schematic diagram of a gas automatic gas closing valve.

Detailed ways

The gas automatic closing valve includes a solenoid valve 1 and a timing circuit module 4, the inlet joint 5 of the solenoid valve 1 is connected to the gas pipeline, and the gas outlet joint 6 of the solenoid valve 1 is connected to the gas source inlet of the gas stove. The timing circuit module 4 is provided with a battery box 7 , a battery pack 8 and a regulating device. The adjusting device is a timing switch 2 and an adjusting knob 3 arranged on the timing circuit module 4 . For the convenience of use, the timing switch 2 and the adjusting knob 3 are arranged on the outer wall of the gas stove at positions that are convenient for operation. The timing circuit module 4 is respectively connected with the solenoid valve 1 and the battery box 7 through wires.

Its working principle is: after the user ignites the cooker, first set the fire time by adjusting the knob 3 according to the needs, and then press the timer switch 2 to start timing. After the set time is reached, the timer circuit module 4 drives the solenoid valve 1 to close and cut The gas source realizes the timing and automatic shutdown of the gas stove. If the fire is used up before the set time, the gas stove can be turned off manually as in normal use, and the regulating device will automatically reset after reaching the set time. If you still need to continue to use the fire after the set time is reached and the gas source is cut off, you only need to ignite the fire again and reset the time. The utility model has the advantages of simple structure and convenient operation, which can avoid accidents and losses caused by forgetting to turn off the fire when it is installed on the gas cooker.
