Embodiment 1

[0027]SeeFigure 1-4 , The present invention provides a technical solution: a gas cylinder quick automatic shut-off valve includes a main pipe body 10, one end of the main pipe body 10 is connected with an air inlet pipe 11, the air inlet pipe 11 is movably sleeved with an external threaded joint 111, and the other end of the main pipe body is provided with In the internal threaded joint 12, a ball valve 13 is arranged in the main pipe body 10, and a valve stem 14 is connected to the upper end of the ball valve 13, and the valve stem 14 extends upward through the main pipe body 10 to extend outside;

[0028]The driving mechanism 20 includes a first housing 21 and a motor 23. The first housing 21 is arranged on the upper side of the main body 10, and a connecting plate 24 is arranged at the lower end of the first housing 21. The connecting plate 24 passes through a fastening assembly 30 Connected to the main body 10, the motor 23 is fixedly installed inside the casing, the output shaft o...

Embodiment 2

[0036]SeeFigure 1-3A magnet 44 is fixedly installed on the other side of the second housing 41. The gas detection mechanism 40 can be adsorbed on the gas cylinder through the magnet 44. When a gas leak occurs, the gas leak can be detected in time and the main body 10 is cut off. Respond in time to further improve the safety performance.

Embodiment 3

[0038]Seefigure 1 ,figure 2 ,Figure 5 ,Figure 6 ,Figure 7 withFigure 8 A suction pump 60 is fixedly installed on the inner bottom wall of the second housing 41. A suction pipe 61 is provided on the side of the suction pump 60 close to the air intake groove, and an exhaust pipe 62 is provided on the side far away from the air intake groove. The tube 62 extends upward through the second housing 41 to the outside. The left and right ends of the second housing 41 are respectively provided with a connecting plate 70, a fixing sleeve 71 is provided on the connecting plate 70, and a supporting rod 80 is penetrated in the fixing sleeve 71, A telescopic rod 81 is connected to the outer end of the support rod 80.

Abstract

The invention discloses a quick automatic cut-off valve for a gas cylinder. The quick automatic cut-off valve comprises a main tube body, a drive mechanism and a gas detection mechanism, wherein one end of the main tube body is connected to a gas inlet pipe, the gas inlet tube is movably sleeved with an external thread connector, the other end of the main tube body is provided with an internal thread connector, a ball valve is arranged in the main tube body, and a valve rod is connected to the upper end of the ball valve; the valve rod upwards gets out of the main tube body; the drive mechanism comprises a first shell and a motor; the first shell is arranged at the upper side of the main tube body; a connecting plate is arranged at the lower end of the first shell; the connecting plate isconnected to the main tube body through a fastening assembly; the motor is fixedly mounted inside the shell; the output shaft of the motor is in drive connection to the valve rod; a controller is arranged in the shell; the controller is electrically connected to the motor; the gas detection mechanism comprises a second shell and a gas-sensitive inductor which is fixedly mounted inside the second shell. While gas leakage occurs, the main tube body can be quickly cut off, so that gas in the gas cylinder stops conveying outwards, and thus, the quick automatic cut-off valve is high in safety and is high in practicability.

Description

Technical field[0001]The invention relates to the technical field of gas leakage prevention, in particular to a gas cylinder quick automatic shut-off valve.Background technique[0002]In ordinary household kitchens, gas cylinders are used to store gas stoves for cooking. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas and biogas, and coal gas.[0003]The existing gas cylinder is connected to the gas stove through a hose, which is likely to cause gas leakage due to loose connection clamps, aging and cracking of the hose, rat bites or other factors, leading to gas safety accidents. Therefore, the present invention proposes to solve the above problems. The problematic cylinder quickly shuts off the valve.Summary of the invention[0004]The purpose of the present invention is to provide a quick automatic shut-off valve for gas cylinders to solve the problems raised in the background art.[0005]In order to achieve the above object, the present invention ...
