First air feed path is from air feed path inlet side, is connected with magnetic valve 110, Pressure gauge 130, pressure-reducing valve 150, Pressure gauge 140, safety valve 160 and magnetic valve 120 in turn.Magnetic valve 110 is for controlling the circulation of the gas from air supply source; Pressure gauge 130 is for detecting the pressure of the gas from air supply source; Pressure-reducing valve 150 is by the high pressure relief from air supply source air-flow to the pressure limit that can be used in detecting, and safety valve 160 is for ensureing detection system safety; Magnetic valve 120 for controlling the circulation of air-flow to two detection path, from the gas of air supply source feed to detection path via after this magnetic valve.
Connect detection path after air feed path, present embodiment is connected with two detection path, also can change as required.
Air feed path is branch's two-way after magnetic valve 120, be communicated with detection path A, B respectively by proportional dump valve 170A, 170B, proportional dump valve 170A, 170B are driven by analogue collection module 220, the pressure of detection path can be adjusted to be detected section of pressure needed for target detection thing.
Detection path A is connected with 3 position-5 way magnetic valve 180A, electrical ball valve 190A and Pressure gauge 200A in turn after proportional dump valve 170A, is finally communicated with target detection thing.3 position-5 way magnetic valve 180A is used for detection path and exhaust described in opening and closing; Electrical ball valve 190A is for realizing the absolute tightness of this detection path; Pressure gauge 200A is used for the force value detecting gas in target detection thing in real time.
Detection path B is connected with 3 position-5 way magnetic valve 180B, electrical ball valve 190B and Pressure gauge 200B in turn after proportional dump valve 170B.Each parts connect corresponding identical with detection path A with function.
Each valve is all controlled automatically by switching value acquisition module, and driving and each manometric force value collection of proportional dump valve are realized automatically by analogue collection module.Switching value acquisition module and analogue collection module all carry out communication by RS485 bus.
Control cabinet shown in Fig. 2 is assembled with switching value acquisition module 2 pieces, analogue collection module 2 pieces, power supply 2 pieces.
The control core of native system is strong formula integrated computer, supporting airtight inspection software is arranged in strong formula integrated computer, realize the automation of whole airtight testing process, automatic fast aeration is realized mainly through the opening and closing of each proportional dump valve of Based Intelligent Control and magnetic valve and aperture, by Real-time Collection gage pressure value, and FEEDBACK CONTROL adjustment the blowing pressure realizes accurate pressure regulation, whether exceed standard whether realize automatic interpretation detection data qualifier by calculating testing process range of pressure fluctuations.
When carrying out the airtight detection of thunder bullet product, a point following step completes: self-inspection stage, aeration phase, equilibrium stage, test phase and empty stage.
The self-inspection stage: air supply hose is connected with system gas circuit entrance, after system power supply, switching value acquisition module 210 drive magnetic valve 110,120,180A, 180B open, analogue collection module 220 drives proportional dump valve 170A, 170B to start working, and first blows down the various impurity in device internal duct and joint; Then with flexible pipe, air tightness detecting system two outlet is connected, carry out equipment self-inspection, switching value acquisition module 210 drives electrical ball valve 190A, 190B closed, analogue collection module 220 gathers the pressure data of Pressure gauge 200A, 200B and is uploaded to host computer by RS485 bus, airtight inspection software supporting in host computer is by the change of real-time monitor force, and whether automatic decision air tightness detecting system exists leakage.
Aeration phase: the flexible pipe pulling down connection two outlet, with flexible pipe, two outlets and amphitypy product to be measured (can be two thunders or two bullets or thunder bullet) be connected respectively, then in airtight inspection software, Selecting parameter or input is carried out, after air tightness detecting system receives and gets out enabling signal, send control signal, by switching value acquisition module 210 by magnetic valve 180A, 180B opens, and open electrical ball valve 190A, 190B, inflate to product workpiece, proportional dump valve 170A, 170B ensures to be inflated to the pressure of specifying, after reaching authorized pressure, host computer sends signal and makes magnetic valve 180A, 180B and electrical ball valve 190A, 190B closes, aeration phase terminates.
Equilibrium stage: at equilibrium stage, magnetic valve 180A, 180B and electrical ball valve 190A, 190B all close.Because test product internal pipeline is complicated, test product holds cavity temperature and ambient temperature imbalance simultaneously, needs time enough, reaches plateau to make system internal gas pressure.After this stage terminates, in detection system, pressure reaches balance, the force value of detection system is saved, as judging whether product to be measured exists the compression force reference value of leakage.
Test phase: after system internal gas pressure reaches plateau, start to carry out Real-time Collection and monitoring to every data, namely test phase is entered into, at test phase, each valve is all identical with the valve state of equilibrium stage, if there is Leakage Gas, then test product internal pressure reduces, pressure change in test product cavity volume can be recorded by Pressure gauge, and is sent to host computer in real time by analogue collection module 220, thus makes correct judgement to the air-tightness of product.
Empty stage: after above each operation completes, host computer controls electrical ball valve 190A, 190B by switching value acquisition module 210 and opens, and control 180A, 180B are exhausted, gas in test product is all entered air, System recover is to atmospheric pressure, and all valves are returned to original state, for the airtight detection of next part product is ready.
In the utility model, two detection path can work simultaneously, independent control, both airtight detection can be carried out to single thunder bullet product, also can carry out airtight detection to the thunder bullet product of two different models simultaneously, by carrying out Selecting parameter or input in airtight inspection software, the fast aeration of airtight testing process can be realized, accurate pressure regulation, detects continuous acquisition and the automatic interpretation of data.
The unspecified part of the present invention belongs to general knowledge as well known to those skilled in the art.
