Simple leakage detection instrument for liquid container and using method thereof

Abstract

The invention relates to a simple leakage detection instrument for a liquid container and a using method thereof. The instrument comprises a high-pressure gas source (1) and a U-shaped tube (6), wherein the two sides of the U-shaped tube (6) have different tube wall thicknesses and are filled with liquid (Y); the high-pressure gas source (1) is connected with a thin tube inlet in the U-shaped tube (6) through a gas inlet guide tube (5) in which a pressure-stabilizing valve (2) and a stop valve (4) are connected in series; the U-shaped tube (6) is vertically arranged and provided with an upward orifice; and a gas outlet guide tube (7) is connected to a thick tube outlet of the U-shaped tube (6). The using method of the instrument is simple and comprises the following steps that: the gas outlet guide tube (7) is communicated with a detected container device (8), and the stop valve (4) is opened to perform high-pressure gas transmission, wherein the sealing property of the detected container device (8) (such as a container piece, or a pipeline piece with volume) is unqualified if continuous rising bubbles (P) are generated in the liquid (Y) in the thick tube section of the U-shaped tube (6), and the sealing property of the detected container device (8) is qualified if the continuous rising bubbles (P) are not generated in the liquid (Y).

Description

technical field [0001] The invention relates to leak detection technology, in particular to a simple and convenient method for using a liquid container leak detection instrument. Background technique [0002] The most commonly used simple leak detection method for container devices is: such as the "water leak detection" method for bicycle inner tube leak detection in water. Small container-type test pieces, however, cannot be leak-tested on dry land. [0003] If the above-mentioned simple and rapid liquid leak detection method can be applied on dry land to detect leaks of containers, even for large boilers or large piping systems such as large boilers or large piping systems before they are put into use, such a simple liquid type rapid leak detection can be performed method, wouldn't it be better? Contents of the invention [0004] Purpose of the present invention: to apply and expand the above-mentioned "water leak detection" test principle to the extent that it can als...
