Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1-Fig. 3, medical filter leakage testing device comprises support body 1, is fixed on water tank 2 in the support body, is installed in the electric cabinet 20 on support body one end and is arranged on the castor 22 of support body bottom.Filter dive cylinder 16 is equipped with by dive cylinder erecting frame in place, the corresponding water tank of described support body top position, and by shutoff cylinder erecting frame the clamping cylinder 8 that can move up and down and the shutoff cylinder 23 of horizontal motion is installed.Described dive cylinder erecting frame comprises dive cylinder linear axis web joint 3, dive cylinder supports plate 13 and dive cylinder web joint 14, at dive cylinder linear axis web joint 3 two ends dive cylinder linear axis 4 and dive cylinder linear bearing 19 are installed respectively, it is fixing with dive cylinder web joint 14 that described dive cylinder linear axis passes dive cylinder supports plate 13.The affixed dive riser 17 of described dive cylinder supports plate 13 central bottom and the dive base plate 21 that is connected with dive riser 17 are provided with filter pedestal for placed 6 at dive base plate 21.Described filter dive cylinder 16 is packed on the dive cylinder web joint 14, and its piston rod is connected with dive cylinder supports plate 13 by screw 15.
Described shutoff cylinder erecting frame comprises that symmetry is installed in shutoff cylinder mounting bracket 9 and the shutoff cylinder linear axis mounting bracket 11 of bottom, dive cylinder supports plate 13 two ends, is equipped with shutoff cylinder linear axis 10 and shutoff cylinder linear bearing 12 on the described shutoff cylinder linear axis mounting bracket.Described shutoff cylinder linear axis 10 is connected with shutoff connecting link 7 by shutoff cylinder linear bearing 12, and filter shutoff 5 is equipped with in described one of them shutoff connecting link lower end, and the other end of filter shutoff is by shutoff rubber cushion 25 Bonding pressure relays; Another shutoff connecting link 7 lower ends are connected with pressure detection shutoff 18, and pressure detection shutoff 18 1 ends are by shutoff rubber cushion 25 Bonding pressure sensors.In the present embodiment, adopt two symmetrically arranged shutoff cylinders 23, each shutoff cylinder one end is connected with shutoff cylinder mounting bracket 9, the other end connects shutoff connecting link 7, described clamping cylinder 8 upper ends are connected with shutoff cylinder mounting bracket 9, clamping cylinder 8 is used for pushing down respectively two interfaces of filter 24 so that filter shutoff 5 with pressure detection shutoff are connected can distinguish exactly and are connected with two interfaces of filter.The effect that compresses cylinder 8 is fixing filter three-pronged connector, moves when preventing the shutoff of shutoff cylinder and causes shutoff not tight, and error causes leaking hunting.
Described electric cabinet 20 is provided with manual enclosed switch, hand-operated lifting switch, emergency stop switch, manual gas-filled switching tube, manual-automatic switch and automatic start switch, after control starts automatically, finishes exercises by programmed control.
Principle of work of the present utility model is: forward manual-automatic switch to automated location, operating personnel are placed on filter on the dive base plate 21 of leakage testing device, and two interfaces of filter are placed above the filter pedestal for placed 6, again gas-charging connection is connected to the filter interface.At this moment, start automatic start switch, two clamping cylinders 8 are descending and two interfaces of filter are fixed simultaneously, then automatically start two symmetrically arranged shutoff cylinders 24 in opposite directions direction motion, and the shutoff 18 of the filter shutoff 5 of promotion Bonding pressure relay and Bonding pressure sensor moves in opposite directions and two Interface realizations of filter can be sealed, whether filter shutoff 5 detects connectors unobstructed, and whether shutoff 18 namely detects connector unobstructed and carry out pressure detection.As shown in Figure 3, the inflation of filter 24 is by inflation inlet 24-1 air inlet, and admission pressure can be set.Filter shutoff 5 left ends connect the unobstructed detection that pressure switch carries out three-pronged connector, if unobstructed namely have signal output, under shutoff 18 right-hand member three-pronged connectors also unobstructed condition, pressure transducer just carries out the pressure detection of filter.Pressure switch is connected on the pressure display unit by tracheae, reaches the closed output signal of pressure back contact and judges that three-pronged connector is unimpeded.
Start hand-pump system, make it reach setting value by gas charging system to the filter inflation, pressure switch action proof trident connector is unimpeded, then automatically starts next program shutoff 18 and detects the unimpeded detection of three-pronged connectors and reach set pressure.
Start the hand-operated lifting switch, the dive cylinder crane DL synchronization that the automatic lifting program makes filter dive cylinder 16 and is made of dive cylinder linear axis 4, dive cylinder supports plate 13, dive riser 17 and dive base plate 21 etc., and filter is immersed then carry out leak test in the water tank and detect.After the leak test detection reached setting-up time, the formation cranes such as filter dive cylinder 16 and dive base plate 21 rose synchronously, if leakage phenomenon occurs in the leak test testing process, filter dive cylinder and dive cylinder crane can automatic-ascending and warnings.
This device also is provided with autoalarm, and autoalarm is installed in the pressure display unit, finishes warning by different acoustic realization fault alarm and detection.
