Gas tank gas supply safety device

Abstract

The invention provides a air feed safety device of fire-damp pressure chamber, that is arranging an up-down moving spring tip a in a tip base hole arranged in a contact end at fire-damp pressure chamber top air feed position, and arranging an air hole communicated with the tip base hole at external end of the contact end, and an end of the air hole is connected to a stove burner by a mash gas pipe, on the other end a metering pin valve capable of adjusting air supply is screwed, a pair of switching elements having a top control section corresponding to the upper end of the spring tip are pivoted on the contact end; when the switching elements rotate upwards, the top control section pushes the spring tip to make the lower end of the spring tip push the air feed nozzle to discharge, the mash gas is supplied to the stove burner through the tip base hole, air hole and the pipe, however if the pressure in the mash gas chamber is over high, the mash gas pressure may push the spring tip upwards, thus the switching element naturally slide down, the spring tip releases the air feed nozzle to stop air feed, which ensures the safety of gas oven.

Description

technical field [0001] The present invention provides a gas tank gas supply safety device, so that when the gas supply adjustment joint is installed, the danger of gas leakage will not occur at all, and at the same time, when the pressure in the gas tank is too high, it will automatically shut down and stop the gas supply. Gas, thereby ensuring the safety of the stove and users. Background technique [0002] Generally, the gas supply gas tank of a portable field mini-stove usually has a gas supply nozzle in the middle of the upper recess that can be pressed to release the gas gas, and the gas tank supplies gas to the stove as follows: figure 1 Shown, be to establish a joint 1 to be provided with upper and lower screw holes 11,12, and set a jack post 14 below the wall portion 13 between the two screw holes, and on the wall portion 13 around this jack post 14 A plurality of perforations 15 are provided, and the screw hole 11 at the upper end of the joint 1 is screwed with the...

AI Technical Summary

Problems solved by technology

[0003] However, no matter the gas tank joints for supplying gas of the aforementioned two different stoves all adopt the same structural method, but all have the same problem that needs to be improved. During the process, the gas supply nozzle 22 will be pushed down slowly, causing the gas to be released immediately, and then overflow from the gap of the screw joint. Therefore, users often have an experience that when the joint 1 When screwed with the gas tank 2, there will be high-pressure gas leakage and sound, which will not only waste gas, but also cause danger due to gas leakage

[0004] Secondly, when the gas is supplied to the stove for combustion, if the abnormal pressure in the gas tank 2 increases, it may cause the fire to increase in vain and cause danger to the user, but the stove we have seen so far There are no safety measures to ensure the safety of users
