Abstract
The utility model relates to an air bottle vacuum test system, comprising a computer test platform, a tested valve and a vacuum pump, wherein the tested valve is laid in one thermotank and heated by a heating rod which is controlled by a solid state relay on the computer test platform and the thermotank is communicated with the vacuum pump and the computer test platform controls the temperature and pressure in the thermotank by measuring the data received from a measuring pressure transmitter and the tested valve heating device temperature measuring element, and the temperature transmitter by vacuum. The computer automatically controls the whole test process and the data processing is accurate, therefore the whole test system reliability is high and the operation is stable and the maintenance work is reduced.
Description
Technical field
The utility model relates to a kind of computer testing system, relates in particular to a kind of bottle valve vacuum test system.
Background technology
Present test to bottle valve vacuum test performance index, because test macro will adapt to great pressure constant interval (0.05～45MPa), and many devices (as common variable valve, solenoid valve) can't operate as normal when high pressure, promptly enable operate as normal, also short, the reliability reduction of its life-span, therefore, we also consider this point when carrying out the whole test system conceptual design.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of bottle valve vacuum test system, solves in the prior art when high pressure normally worker's defective.
Technical scheme
A kind of bottle valve vacuum test system, comprise the computer testing platform, tried valve, vacuum pump, the described valve that tried is placed in the constant temperature oven, heat by heating rod, described heating rod is controlled by solid-state relay TV by the computer testing platform, described constant temperature oven and vacuum pump communicate, and described computer testing platform is by vacuum measurement pressure unit PT and tried temperature and pressure in the Data Control constant temperature oven that valve heating arrangement temperature element TE, temperature transmitter TT receive.
A check (non-return) valve FZ is housed between described vacuum pump and constant temperature oven, and it leads to is that constant temperature oven leads to vacuum pump.
Temperature display watch TI and vacuum measurement pressure display table PI all are housed on described temperature transmitter and the vacuum measurement pressure unit.
Beneficial effect
The utility model is by the computer controlled automatic whole test process, so data processing accurately makes whole test system reliability height, working stability reduces maintenance work.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
This experimental test scheme is tried valve and is placed constant temperature oven as shown in Figure 1, and constant temperature oven carries temperature control equipment, and computer testing system can be communicated by letter with this device.Test macro is at first opened gas admittance valve, is tried the valve pressure stability near atmospheric pressure the time, computer testing system start-up temperature regulating device, when temperature reaches regulation, stop to heat up, close gas admittance valve, test macro begins to vacuumize, and when reaching specified vacuum degree 13.3Pa, stops to vacuumize.Test macro continuous detecting vacuum tightness if vacuum tightness does not descend in official hour 8 hours, is then opened gas admittance valve, stops the constant temperature oven temperature control system.The test macro function
(1) vacuum tightness is controlled automatically;
(2) temperature is controlled automatically
(3) vacuum tightness detects automatically;
(4) gas control interlocking.
The correspondence position of wiring shown in Fig. 2,3 of device joins.
