Abstract

The invention discloses a sealing performance detection device, and relates to the technical field of sealing performance detection. The device comprises an operation table, a detection container is arranged at the upper end of the operation table, and a controller used for controlling the detection container is further arranged at the upper end of the operation table; the detection container comprises an upper cover, a flange frame, a lower cover and a transparent acrylic cylinder. Through the design of electromagnetic sealing, the sealing performance is stable, and the defect that the sealing performance slides down due to aging of a mechanical locking structure is completely overcome; the traditional principle that a cylinder pneumatically controls the lifting of an objective table is changed into the principle that an electromagnet is electrified to generate magnetic force, so that the problems of failure and danger caused by water leakage to damage an equipment circuit and the like due to aging of a mechanical locking sealing structure of the cylinder and a lower cover and sealing performance reduction caused by overlarge detection air pressure are effectively avoided. Through the cooperative design of the multiphase flow sensor, the misjudgment probability caused by human eye observation is reduced.

Description

technical field [0001] The invention relates to the technical field of leak detection, in particular to a leak detection device. Background technique [0002] In the traditional airtightness test, pressurized gas is first poured into the airtight container where the product to be tested is placed, and then the product to be tested is put into water (the stage is driven down by the cylinder until the product to be tested is submerged in water). The container is depressurized and exhausted. If bubbles appear in the water, it means that the product to be tested is not sealed, and vice versa; [0003] However, in the traditional sealing test, the sealed lid needs to be taken and placed manually. When the lid is heavy, it is even more labor-intensive. The upper lid and the flange locked by the mechanical locking structure ensure the airtightness of the container itself, but the mechanical structure uses After a long time, it will age and loosen, and the locking force is not enou...
