Embodiment
As shown in Fig. 1 ~ Fig. 4, the reverse air-tightness detection device of a kind of full-automatic outlet valve, comprises cabinet 1, cabinet 1 is provided with industrial computer 2, cabinet 1 is provided with on instrument 3, described cabinet 1 fixture 5 is installed, and fixture 5 connects cylinder, and fixture 5 is controlled its clamping and unclamped by cylinder.
In cabinet 1, be provided with and detect gas circuit 4.On cabinet 1, be also provided with manual operation interface 6, computer operation interface 7.
Described detection gas circuit 4 comprises constant volume cavity 4-2, evacuating valve, venting valve, in constant volume cavity 4-2, be provided with pressure transducer 4-1, constant volume cavity 4-2 jockey 5, pressure transducer 4-2 connects industrial computer 2, industrial computer 2 connects evacuating valve, venting valve, and constant volume cavity 4-2 connects vacuum pump 4-8 by evacuating valve.Described vacuum pump 4-8 is provided with flowmeter, often opens ratio adjusting valve 4-7, vacuum pump 4-8 by flowmeter, often open ratio adjusting valve 4-7 and connect evacuating valve.Described evacuating valve is solenoid valve 4-5 or the hand valve 4-6 that bleeds of bleeding, and described venting valve is venting hand valve 4-3 or pressure-releasing electromagnetic valve 4-4.
As shown in Figure 3, described instrument 3 comprises: digital display manometer 3-1, flow of digit display table 3-2, digital display stopwatch 3-3.
As shown in Figure 2, manual operation interface 6 by: airtight measurement button 6-1, airtight measurement stop button 6-2, clamp pressing button 6-3, fixture release button 6-4, extraction valve 6-5, air release 6-6 form.
The course of work:
Outlet valve is installed on fixture 5, opens dedicated test software, click starting outfit.Click and start test button or press airtight measurement button 6-1, cylinder operation, fixture 5 clamps, vacuum pump 4-8 starts automatically simultaneously, and now flowmeter detects and vacuumizes flow, by detection software picture and flow of digit display table 3-2, is shown and is vacuumized flow, simultaneously, flow signal is passed to industrial computer 2 through flow transmitter, and industrial computer 2, according to setup parameter, is controlled and is often opened the automatic bleeding regulating flow of ratio adjusting valve 4-7 by I/O control card.After flow reaches and set to require, industrial computer 2 is opened automatically by the I/O control card solenoid valve 4-5 that bleeds; Or can realize by the hand valve 4-6 that bleeds.Now constant volume cavity 4-2 is vacuumized, by detecting software picture and digital display manometer 3-2, show negative pressure value.
