Embodiment

[0025] 1) Positive and negative pressure inspection operation of the breathing valve:

[0026] (1) Turn off the power switch of the vacuum pump, turn the air-operated three-way valve 14 to the positive pressure detection position and connect with the breathing valve 13;

[0027] (2) The power supply of the booster pump is powered on, and the booster pump inflates the buffer gas tank;

[0028] (3) Open check valve 5;

[0029] (4) Adjust the pressure regulating valve 6, and observe the breathing valve 13 and the pressure gauge 7 to see if the exhaust can be exhausted within the specified pressure, if the exhaust is qualified;

[0030] (5) close check valve 5,

[0031] (6) Turn on the power supply of the vacuum pump, and the vacuum pump will evacuate the buffer gas tank,

[0032] (7) Open the one-way valve 18, observe the vacuum value of the vacuum gauge, and close the vacuum pump when the vacuum reaches the standard prescribed negative pressure;

[0033] (8) Rotate the three...

Abstract

The invention provides a comprehensive air pressure test bed for a vehicle-mounted steel tank, of which structure is composed of a test bed, a positive / negative pressure source, a tested tank positive pressure test pipeline, a loading-unloading flexible pipe positive pressure test pipeline, a breather valve positive pressure test pipeline and a breather valve negative pressure test pipeline, wherein the positive / negative pressure source, the tested tank positive pressure test pipeline, the loading-unloading flexible pipe positive pressure test pipeline, breather valve positive pressure test pipeline and the breather valve negative pressure test pipeline are installed in the test bed, the positive / negative pressure source is composed of a pressure pump and a vacuum pump connected with a buffering air tank by a pipeline; and an air source is connected with a tested tank connector by being connected in series with a first three-way pipe, a first one-way valve, a first pressure regulating valve, a pressure gauge, a second three-way pipe and a third one-way valve through the pipelines to form the tested tank positive pressure test pipeline; the comprehensive air pressure test bed for the vehicle-mounted steel tank has benefits of effectively solving a problem of detecting air tightness of the vehicle mounted tank and comprehensive quality performance of the breather valve and the unloading flexible pipe.

Description

technical field [0001] The invention relates to a test device, in particular to a vehicle-mounted steel tank air pressure comprehensive test bench. Background technique [0002] Fuel oil and many flammable and explosive chemical raw materials need to be stored or transported using steel pipes, and the steel pipes on the vehicle also need special hoses for loading and unloading. The breathing valve does not have systematic testing equipment for comprehensive inspection and testing, which brings potential safety hazards to production and user use. Contents of the invention [0003] The technical task of the present invention is to overcome the above disadvantages and provide a vehicle-mounted steel tank air pressure comprehensive test bench with simple structure, reasonable design, convenient use, and fast and safe detection of vehicle-mounted tanks, breathing valves and loading and unloading pipes. [0004] The technical solution of the present invention is realized in the...
