Description

Technical Field

[0001] This utility model relates to the field of angle valves, and more particularly to a safety angle valve for gas cylinders. Background Technology

[0002] Angle valves are commonly used to control fluids in pipelines. They are also called angle valves or angle-type valves. Gas cylinder angle valves are valves installed on cylinders containing liquefied petroleum gas, propane, butane, etc., to control the flow and stop of gas. Gas cylinder angle valves are usually located on the valve head of the cylinder and are used to connect to the gas pipeline and control the output of gas.

[0003] When gas cylinder angle valves are used in environments such as kitchens, a layer of oil often adheres to the surface of the valve, making maintenance of the gas cylinder angle valve more complicated. Secondly, gas cylinder angle valves are sometimes damaged by bumps during operation. Furthermore, the connection of the gas outlet of traditional gas cylinder angle valves is quite complicated, and it takes a lot of time to remove the connecting pipe.

[0004] Therefore, those skilled in the art have provided a safety angle valve for gas cylinders to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a safety angle valve for gas cylinders. By fitting the pipe to be connected into the clamping ring and the fixing shell, and then cooperating with the limiting ring, the connected pipe can be fixed through the internal and external threaded grooves.
