Detailed Description
The present invention will be described in further detail with reference to the following embodiments and the accompanying drawings.
In the embodiment, the catalyst is placed on the detection table, the air inlet pipe and the air outlet pipe of the catalyst are blocked by the cylinder to keep the whole sealing performance, and the pressure difference pipes at the front end and the rear end are connected together in parallel by the connecting piece.
As shown in figures 1-3, the utility model discloses a catalyst airtightness detection mechanism, which comprises a detection table for placing a catalyst main body, wherein a support base 1 is arranged on the detection table, two guide rail cylinders 2 with the same propelling direction are arranged on the support base 1, push rods of the two guide rail cylinders 2 are parallel to each other, a support plate 3 is arranged on the support base 1, a pressure groove 4 is arranged on the support plate 3, a connecting pipe 5 connected with a differential pressure pipe is arranged in the pressure groove 4, and a plug head 6 for performing piston motion in the connecting pipe 5 is arranged at the front end of the push rod.
The connecting pipe 5 is divided into a front section connected with the differential pressure pipe and a rear section connected with the push rod, the diameter of the front section is smaller than that of the rear half part, the principle is that the pressure action on the section of the front section and the section of the rear section is mutual, but the sectional area of the front section is smaller than that of the rear section, so that the pressure of the rear section is smaller than that of the front section, and the power required by the guide rail cylinder 2 can be smaller.
The front section is positioned in the pressure groove 4, and the plug head 6 is tightly attached to the inner wall of the rear section to move. Be provided with the corresponding spinning cylinder 7 with indent 4 on the backup pad 3, the anterior segment diameter is littleer better compresses tightly in indent 4.
In the preparation stage, the front section of the connecting pipe 5 is connected with the differential pressure pipe through the threaded flange, so that the connection between the connecting pipe and the differential pressure pipe is tighter, and the accuracy of air tightness detection is also ensured.
The push rod is provided with a position mark along the length direction of the push rod, the position mark is a length mark, if the air tightness is in a problem, the serious degree of the air tightness can be visually embodied, and the advancing speed of the push rod is higher if the problem is serious.
The specific implementation is that the connecting pipe 5 is tightly connected with the differential pressure pipe, the air inlet pipe and the air outlet pipe are blocked by the cylinders, which is equivalent to that the inside of the whole catalyst is a closed space, if the inside of the air tightness of the catalyst has no problem, the guide rail cylinder 2 can not push the plug head 6 in the connecting pipe 5 to slide, and if the inside of the air tightness of the catalyst can be pushed, the air tightness of the catalyst is indicated to have a problem.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the embodiments are only used to help understanding the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the present description should not be construed as a limitation to the present invention.
