Embodiment Construction

[0022] like Figure 1-4 As shown, the gas pipeline is automatically closed when the temperature drops, including a first gas pipeline 1 and a second gas pipeline 2, and a sleeve 3 is sealed between the first gas pipeline and the second gas pipeline. The lower inner wall at the port of the first gas pipeline in the pipe is hinged with a first magnet 4. The first magnet is a valve for closing the first gas pipeline. The magnetic poles of the first magnet are located at the upper and lower ends respectively; A second magnet 5 is provided, and the second magnet is located above the first magnet at the same time, and the magnetic poles of the second magnet are also located at the upper and lower ends respectively, and the second magnet can be flipped up and down. The opening of the first gas pipeline is an oblique section, and the oblique section faces downward, which is convenient for the first magnet to close the first gas pipeline.

[0023] The second magnet is a nickel-iron al...

Abstract

The invention discloses an automatic closing device for a gas pipeline during cooling. The automatic closing device comprises a first gas pipeline and a second gas pipeline; a casing pipe is sealed between the first gas pipeline and the second gas pipeline in a sleeved manner, a first magnet is hinged to the inner wall below the position, arranged in the casing pipe, of a first gas pipeline port, a first magnet is used by a valve to close the first gas pipeline, and magnetic poles of the first magnet are located at the upper end and the lower end; a second magnet is arranged above the casing pipe, and the second magnet is located above the first magnet at the same time; magnetic poles of the second magnet are also located at the upper end and the lower end, and the second magnet can vertically turn over; and the second magnet is a ferro-nickel magnet, and is connected with a thermosensitive metal line, and a probe at the other end of the thermosensitive metal line is connected to a cooking bench to be used for temperature measuring. The automatic closing device is obviously stable in effect, and the potential safety hazard that the cooking bench flames out accidently, and gas leakage is caused can be effectively eradicated.

Description

technical field [0001] The invention relates to a pipeline closing device, in particular to an automatic closing device for gas pipelines when the temperature drops. Background technique [0002] During cooking, the gas stove is often adjusted to a low fire state, and the wind from the window and the overflow of soup may extinguish the flame; in addition, the gas supply pressure is insufficient, intermittent, and the flame fluctuates up and down, and the flame may also go out. Turn off the flame, and the gas will leak immediately. People are usually not in front of the stove when stewing food with a low fire. If you continue to be busy with other affairs at this moment, you don't know that a potential safety hazard has quietly arrived. Contents of the invention [0003] In order to overcome the defects of the prior art, the object of the present invention is to provide a device for automatically closing the gas pipeline when the stove is turned off to cool down. [0004]...
