Abstract

The invention discloses a system for package container constant temperature airtight test. The system comprises a first water supply pipeline, a second water supply pipeline, a first water pump, a water tank, a first air supply pipeline, a first exhaust pipeline, a controller, a display and a water supply device; the water tank comprises a water channel and an upper cover; an inlet of the first water pump is communicated with the first water supply pipeline, an outlet of the first water pump is communicated with the water channel through the second water supply pipeline; a first control valveis arranged on the first water supply pipeline, and a second control valve is arranged on the second water supply pipeline; a right side of the upper cover is hinged with the right side of the water channel; a pressure-stabilizing valve, a first air inlet valve and a first pressure sensor are orderly arranged on the first air supply pipeline; one end of the first exhaust pipeline is communicated to the first air supply pipeline at a back side of the first air inlet valve, and a first exhaust value is arranged on the first exhaust pipeline. The airtight test is performed on the package container by utilizing the system, thereby accurately observing and judging whether the container is in leakage and accurately confirming a leakage point of the package container.

Description

technical field [0001] The invention belongs to the technical field of packaging container airtightness test, in particular to a system for constant temperature airtightness test of packaging container. Background technique [0002] Packaging containers are used as equipment for containing chemical and chemical products. Their airtight performance and mechanical properties seriously affect the safety of chemical and chemical product transportation and storage. Therefore, it is necessary to conduct airtight tests on packaging containers to evaluate the airtight performance and mechanical properties of packaging containers. In the traditional airtight test of packaging containers, soapy water is applied to the outside of the packaging container, and then compressed air is added into the packaging container. Damaged leakage, if there is no air bubbles on the outside of the packaging container, it means that the packaging container is not damaged. Using the method of smearing s...
