Gas bottle safety joint

Abstract

The invention discloses a gas bottle safety joint, which includes a knob and a joint body, wherein an inlet joint with a through hole is arranged in the knob, an inlet end of the inlet joint is connected with a nozzle, the through hole part of the inlet joint is a step hole whose diameter at the inlet end is larger than that at the outlet end, a spring is arranged in the through hole part, and a limit piece glidingly matched in the step hole is arranged at an end part, close to the inlet end of the inlet joint, of the spring; and the joint body is divided into an inlet cavity and an outlet cavity, the outlet end of the inlet joint is communicated with the inlet cavity of the joint body, a baffle plate provided with a through hole is formed between the inlet cavity and the outlet cavity, and a gas leakage preventing protective device is arranged in the outlet cavity of the joint body. The gas bottle safety joint has the advantages of overcurrent protection, overheat protection, leakageprotection in case of pressure regulator dismounting by mistake, dynamic display of fuel gas pressure, gas leakage detection from a gas bottle to a stove, and the like. The gas bottle safety joint belongs to the technical field of gas valves.

Description

technical field [0001] The invention belongs to the technical field of gas valves, in particular to a gas cylinder safety joint connected to the gas outlet of the gas cylinder. Background technique [0002] At present, the outlet of propane and liquefied petroleum gas cylinders is connected to a pressure regulator, and the gas outlet end of the pressure regulator is connected to the gas stove. A regulating device that keeps the pressure and flow of gas constant. There is no protective device installed between the gas cylinder and the pressure regulator, which has the following disadvantages: 1. When the outlet pressure of the gas cylinder is too high, it is very easy to cause insufficient gas combustion and gas leakage at the stove in the gas stove; If the outside temperature rises (such as a fire), the gas supply cannot be cut off in time, which will easily cause the gas stove hose to leak and fuel the fire; 3. When the user forgets to close the gas cylinder valve and dire...

Problems solved by technology

There is no protective device installed between the gas cylinder and the pressure regulator, which has the following disadvantages: 1. When the outlet pressure of the gas cylinder is too high, it is very easy to cause insufficient gas combustion and gas leakage at the stove in the gas stove; If the outside temperature rises (such as a fire), the gas supply cannot be cut off in time, which will easily cause the gas stove hose to leak and fuel the fire; 3. When the user forgets to close the gas cylinder valve and directly unscrews the pressure regulator, a large amount of gas Leakage, there are potential safety hazards; 4. In actual use, everyone often does not close the valve of the gas cylinder for convenience, and it is impossible to detect whether there is a gas leak in the pipeline
