A gas leakage calibrator

Abstract

The technical solution of the present invention is: a gas leakage calibrator is composed of a box, an operation control panel, a differential pressure sensor, a zero leakage solenoid valve, a simulated leak plate, an air inlet, and a panel. The operation control panel, the differential pressure sensor, the zero leakage solenoid valve, the simulated leak plate and the air inlet are connected to the box by screws. The air inlet, the differential pressure sensor and the zero leakage solenoid valve are connected to the simulated leak plate through an air pipe, so that the size of the leak hole on the simulated leak plate is automatically adjusted by manually operating the operation control panel, so that the size of the leak hole on the simulated leak plate corresponds to the corresponding leakage rate. First of all, the gas leakage calibrator device has universal applicability and is applicable to wheels of different models. Secondly, it replaces manual calibration, has high accuracy, good repeatability, and greatly improves work efficiency and accuracy. It solves the problem of meeting fast-paced production and accuracy to a greater extent in future production and development processes.

Description

Technical Field

[0001] The invention relates to a gas leakage calibrator, and belongs to the field of automobile production mechanical equipment. Background Art

[0002] At present, gas leakage calibration is done manually, and it is impossible to determine whether the value of each calibration is accurate, which affects the final production data results, and thus repeated calibration affects the production rhythm. In view of this, a gas leakage calibration device is urgently needed in the industry, which can automatically adjust the size of the simulated leak plate through the operation control panel so that the size of the simulated leak plate corresponds to the corresponding leakage rate. Summary of the invention

[0003] In order to solve the problems of unstable manual calibration, low working efficiency, low stability, low data stability, etc., the present invention provides a gas leakage calibrator to solve the problems of the prior art.

[0004] The technical solution of the present invention is that a gas leakage calibrator is composed of a box 107, an operation control panel 106, a differential pressure sensor 104, a zero leakage solenoid valve 103, a simulated leak plate 102, an air inlet 101, and a panel 105. The operation control panel 106, the differential pressure sensor 104, the zero leakage solenoid valve 103, the simulated leak plate 102, and the air inlet 101 are connected to the box 107 by screws, and the air inlet 101, the differential pressure sensor 104, and the zero leakage solenoid valve 103 are connected to the simulated leak plate 102 by an air pipe. Thus, the size of the leak hole on the simulated leak plate 102 is automatically adjusted by manually operating the operation control panel 106, so that the size of the leak hole of the simulated leak plate 102 corresponds to the corresponding leakage rate.

[0005] The advantages of the present invention are as follows: First, the gas leakage calibration device is universally applicable and is applicable to wheels of different models. Second, it replaces manual calibration, has high accuracy, good repeatability, and greatly improves work efficiency and accuracy. Finally, the gas leakage calibration device is easy to operate, has high accuracy, and consumes little time. It solves the problem of meeting fast-paced production and accuracy to a greater extent in future production and development processes. BRIEF DESCRIPTION OF THE DRAWINGS
