Embodiment Construction

[0019] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0020] refer to figure 1 As shown, the present invention provides a method for detecting the sealing performance of plate parts, comprising the following steps:

[0021] The first step is to apply soap liquid on the board parts to be tested;

[0022] The second step is to prepare a cylinder body 2 with a flat bottom, and place the cylinder body 2 on the plate part to be detected, so that a sealed cavity is formed between the cylinder body 2 and the plate part to be detected . In order to improve the detection accuracy and efficiency, it is necessary to arrange a flexible ring-shaped part 3 at the bottom of the cylinder body 2 in advance. The f...

Abstract

The invention relates to the technical field of sealing property tests, and discloses a method for detecting sealing property of plate parts. The method comprises the following steps: step S1, coating liquid soap on a to-be-detected plate part; S2, preparing a cylinder which is smooth on the bottom, placing the cylinder on the to-be-detected plate part, so as to form a sealing cavity between the cylinder and the to-be-detected plate part; S3, using a vacuum pump to vacuate the sealing cavity; S4, and observing whether the to-be-detected plate part has bubbles in real time, if bubbles occur, the sealing property of the part being poor, and if no bubbles occur, the sealing property of the part being good. The method uses the vacuum-pumping method to detect. In detection, the part is coated with the liquid soap, and the cylinder is placed on the to-be-detected plate part, and the vacuum pump is started, and then the sealing property of the part can be determined through observing whether bubbles occur on the to-be-detected plate part.

Description

technical field [0001] The invention relates to a method for testing the sealing performance, more specifically, to a method for testing the sealing performance of plate parts. Background technique [0002] For equipment with high sealing performance requirements, especially large-scale equipment such as ships, most of these equipment are assembled together by welding plate-shaped parts. When the sealing of plate parts is poor, it is easy to cause major safety accidents. Therefore, how to design a method that can quickly test the sealing performance of plate parts to eliminate potential safety hazards is one of the research directions of those skilled in the art. Contents of the invention [0003] The purpose of the present invention is to provide a method for detecting the sealing performance of plate parts that can quickly realize the detection. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is as follows: [0005]...
