Problems solved by technology
[0003] However, when the existing technology is actually used, when the cooking time is relatively long, the user will often leave the kitchen to deal with other things in order to save time. The temperature of the gas valve is also gradually increased. If the user cannot detect and close the gas valve in time, there will be a safety hazard such as an explosion.

Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0025] see Figure 1-6 , the present invention provides a technical solution: including a connecting pipe 1, a first flange 2 is fixedly installed at both ends of the connecting pipe 1, and the end of the first flange 2 far away from the connecting pipe 1 is fixed with a second flange through bolts Two flanges 3, the end of the second flange 3 away from the position of the first flange 2 is fixedly installed with a protection tube 4, and the inner wall of the ...

The invention discloses a safety protection valve for fuel gas. The safety protection valve comprises a connecting pipe, first flange plates are fixedly connected to the two ends of the connecting pipe correspondingly, second flange plates are fixedly connected to the ends, away from the connecting pipe, of the first flange plates through bolts, protection pipes are fixedly connected to the ends,away from the first flange plates, of the second flange plates, and sealing assemblies are fixedly arranged on the inner walls of the ends, away from the connecting pipe, of the protection pipes. Hightemperature is transmitted into the valve, an air storage air bag or a corrugated pipe is deformed or damaged by high temperature, so that air in the corrugated pipe and the air storage air bag flowsout from through holes in a pushing plate, the corrugated pipe and the air storage air bag are in a non-full state, extrusion force is not generated on a driving block any more, therefore, under theaction of damping springs in the sealing assemblies, the sealing assemblies complete isolation sealing operation, gas circulation in the protection pipes and the connecting pipe is avoided, and thus the purpose of high-temperature cutting off is achieved.
Description
technical field [0001] The invention relates to the technical field of gas valves, in particular to a gas safety protection valve. Background technique [0002] Gas valves are mainly used in kitchens, bathrooms and other places. The gas inlet of the gas valve is connected to the gas delivery pipeline, and the gas outlet of the gas valve is connected to the gas equipment through a hose. The user controls the ventilation of the gas using equipment by rotating the manual lever of the gas valve. and die. [0003] However, when the existing technology is actually used, when the cooking time is relatively long, the user will often leave the kitchen to deal with other things in order to save time. The temperature of the gas valve is also gradually increased. If the user cannot detect and close the gas valve in time, there will be a safety hazard such as an explosion. Contents of the invention [0004] The purpose of the present invention is to provide a gas safety protection va...
