Abstract

The invention provides a high-pressure gas cylinder with a valve body with a high-pressure gas buffering function. A valve element is located on the upper portion of the valve body under the action ofa shock absorber and a spring, at the moment, a gas channel of the valve element is located above a gas inlet of a gas inlet guide pipe, and therefore the gas cylinder is in a closed state. When a rotating valve is rotated to enable the valve element to move downwards and the gas channel of the valve element is located at the gas inlet of the gas inlet guide pipe, gas can be sprayed out of the gas cylinder, and due to the fact that a gradually-enlarged ventilation groove is formed in an adjusting plate from bottom to top, and the widest position of the ventilation groove is the same as the gas inlet of the gas inlet guide pipe, through up-down movement of the valve element, the ventilation groove can adjust the flow of the gas sprayed out of the gas inlet of the gas inlet guide pipe, andin addition, a first pressure reduction cavity, a connecting channel and a second pressure reduction cavity form a pressure reduction effect. Therefore, the high-pressure gas cylinder has the high-pressure gas buffering function, gas flow control can be achieved only by rotating the rotating valve, and operation is very convenient.

Description

technical field [0001] The application belongs to the field of pressure vessel devices, and in particular relates to a high-pressure gas cylinder with a high-pressure gas buffer function valve body. Background technique [0002] A pressure vessel is a closed device that holds gas or liquid and carries a certain pressure. In the industry, gas cylinders larger than 8MPa are often called high-pressure gas cylinders. High-pressure gas cylinders are one of the special equipment specified in the "Special Equipment Safety Supervision Regulations". High-pressure gas cylinders are mainly used to store high-pressure gases, and are required to withstand 10 ~30MPa high pressure. [0003] Therefore, the domestic standard high-pressure valves are currently used on gas cylinders. However, when users use them, they often have to be equipped with a pressure reducer or a pressure reducing valve. gas. In addition, users must have certain professional knowledge and safe operation ability of ...
