Problems solved by technology

[0003] However, as a gas source for inflation, it is necessary to continuously fill each gas cylinder with gas, that is, each gas cylinder is individually tested, so that the air tightness detection of each gas cylinder is a repeated step, so that the gas of the gas cylinder The tightness detection takes a long time, which makes the efficiency of the airtightness detection of the gas cylinders low, which seriously affects the utilization rate of the gas cylinders

Embodiment Construction

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention provides a gas cylinder airtightness detection method and device. The method comprises the following steps: carrying out inflation treatment on a gas cylinder group to obtain gas cylinder pressure; detecting whether the gas cylinder pressure is matched with preset pressure or not; and when the gas cylinder pressure is matched with the preset gas pressure, a gas return valve of the gas cylinder group and a gas inlet valve of the next gas cylinder group are opened, so that the gas cylinder group serves as a gas source of the next gas cylinder group. In the process of detecting the gas tightness of the current gas cylinder group, after the gas is filled into the gas cylinder group, when the gas pressure of the gas cylinders reaches the preset gas pressure, the gas tightness of each gas cylinder of the current gas cylinder group is determined to be good, and then the gas in the current gas cylinder group is filled into the next gas cylinder group through the gas return valve and the gas inlet valve; in other words, the gas in the current gas cylinder group is used as the gas source of the next gas cylinder group, so that the gas for detecting the gas tightness is reused, the gas pressurization time when different gas cylinder groups are detected is shortened, and the efficiency of detecting the gas tightness of the gas cylinders is improved.

Description

technical field [0001] The invention relates to the technical field of gas cylinders, in particular to a gas cylinder airtightness detection method and device. Background technique [0002] As the main container for storing gas, the gas cylinder is convenient for transportation during the process of convenient storage, has strong transportation and storage stability, and is convenient for transportation and storage of gas. Among them, the airtightness of gas cylinders is an important product index, which directly determines the qualified rate of gas cylinders. The traditional method is to pressurize and inflate the gas cylinder, and detect the air pressure in the gas cylinder to determine the airtightness of the gas cylinder. [0003] However, as a gas source for inflation, it is necessary to continuously fill each gas cylinder with gas, that is, each gas cylinder is individually tested, so that the air tightness detection of each gas cylinder is a repeated step, so that th...
