Embodiment Construction

[0030] specific implementation plan

[0031] 1) Record the relevant data of the bottle to be tested.

[0032] 2) Install the test bottle

[0033] 3) Exhaust

[0034] Open the valves 16 and 11 to inject test water into the water jacket 15, and close the valve 11 after the air in the water jacket is exhausted A , close valve 16 when the water surface in the measuring tube is aligned with the "level line" of the bracket; open valves 8 and 9, start hydraulic pump 21, stop hydraulic pump 21 after exhausting the air in the pressure-bearing pipeline, and close valve 8 .

[0035] 4) While the internal liquid level position of the pressure measuring tube 1 changes, the height position of the active measuring tube is adjusted when the digital control is driven, so that the absolute position of the internal liquid level remains unchanged

[0036] 5) Stand still

[0037] Automatically read the scale value at the water surface in the measuring tube 1. After standing for 30s, monitor ...

Abstract

The invention relates to a device for testing a gas cylinder by using a computer control moving burette jacket method, belonging to the technical field of gas cylinder quality detection and formed by connecting and assembling a water jacket part, a moving burette part, a pressure detection part, an electric control part and a microcomputer tracking part. The device is characterized by being capable of detecting the liquid level change of a burette, generated by gas cylinder deformation, and being provided with a digital control drive to control the burette position in real time while detecting the liquid level change to ensure that the absolute position of the liquid level in the burette is unchanged. Full deformation and residual deformation are obtained through the burette data change and the residual deformation rate is calculated. The invention solves the problem of easy interference to a weight method by outside conditions, has many hardly avoidable factors of generating errors, such as negative pressure generated by liquid level rise of a weight container, and the like, improves the testing accuracy, ensures that the testing operation is convenient and the result is visual, and is an ideal device for testing the gas cylinder by using the burette hydraulic method.

Description

technical field [0001] Gas cylinders are mobile pressure vessels used internationally. They are used in a wide range and range, and can be filled repeatedly. There are tens of millions of steel seamless gas cylinders in service in my country. Along with the implementation of environmental protection vehicle (such as LPG vehicle) projects and the popularization and application of natural gas vehicles in China, the use of gas cylinders is also increasing day by day. The medium stored in the gas cylinder includes oxygen, nitrogen, hydrogen, oil and natural gas and other high-pressure gases. In order to reduce the possibility of property loss and personal casualties caused by gas cylinder leakage or explosion, it is necessary to conduct regular hydrostatic tests on the gas cylinders before they leave the factory and the gas cylinders in service to determine the elastic and plastic deformation of the gas cylinders. The hydrostatic test of the gas cylinder can accurately obtain th...
