Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the application more clear, the technical solution in the embodiment of the application will be described in more detail below in conjunction with the drawings in the embodiment of the application.

[0028] In order to perform qualitative and quantitative air leakage analysis on mechanical connection holes, the present application provides an air leakage detection device. Such as figure 1 As shown, the air leakage detection device (or air leakage detection sensor) provided by the present application includes a columnar body 1 , an elastic membrane 2 and an optical fiber sensor 3 . The columnar body 1 is roughly columnar, which can be in the shape of a cylinder or a regular hexagon. There is a first opening 11 on the lower end surface of the columnar body 1 , a second opening 12 on the upper end surface of the columnar body 1 , and an inner cavity 14 is formed extending from the first opening 11 to the s...

Abstract

The present application relates to an air leakage detection device, which includes: a columnar body, the columnar body has a first opening on a first end surface and a second opening on a second end surface, from the first opening to the first Two openings are extended to form an inner cavity; an elastic film, the area of ​​which is at least not smaller than the area of ​​the second opening and fixedly covered at the second opening; an optical fiber sensor, the optical fiber sensor is arranged on the first opening Two openings, at least in contact with the elastic membrane, are used to cause the wavelength of the optical fiber sensor to change when the inner cavity is filled with gas to expand and deform the elastic membrane. The air leakage detection device, system and method of the present application can effectively detect whether there is air leakage in the mechanical connection hole. If there is an air leakage phenomenon in the mechanical connection hole, the air leakage detection device and system of the application can quickly give a response, which can effectively achieve real-time detection the goal of.

Description

technical field [0001] The application belongs to the technical field of gas detection, and in particular relates to a gas leakage detection device and method for mechanical connection holes. Background technique [0002] Leakage generally refers to the phenomenon that substances or liquids that should not flow out or leak out in the industry flow out or leak out of mechanical equipment, causing losses. In the mechanical equipment that needs to be sealed, there are various mechanical connection holes, and sealant is applied to the holes or sealing rings to seal them to form a sealed space. However, in actual production and use, due to various uncertain factors, such as loose connections, aging and damage of sealing rings, cracking and peeling of sealants, etc., the sealing performance of some mechanical connection holes cannot meet the requirements, thus occurring The phenomenon of leakage. In order to solve this problem, it is necessary to carry out a tightness test on th...
