Abstract
The utility model discloses a vacuum tester. The tester comprises a pressure reducing valve, a solenoid valve a, a solenoid valve b, a vacuum generator, a T-junction, a pressure sensor, a speed regulator valve, a filter, a test port, a timer and a buzzer. The vacuum generator has two ports. A first port is an air inlet which is connected with compressed air through the solenoid valve a and the pressure reducing valve. A second port is a vacuum port which is successively connected with the pressure sensor and the buzzer through one end of the T-junction. The pressure sensor is successively connected with the timer and an indicating lamp. The other end of the T-junction is connected with a product to be tested successively through the solenoid valve b, the speed regulator valve, the filter and the test port. The tester can be used for detecting a sealing medical apparatus product whose leakage performance is not allowed to be detected by positive pressure, such as the leakage performance of an interventional balloon catheter and the like.
Description
Technical field
The utility model relates to a kind of vacuum test instrument.
Background technology
Because some sealing medical device product do not allow to use positive-pressure detection leaks as got involved foley's tube etc.Therefore, must a kind of negative pressure testing tool of exploitation, there is Non-Destructive Testing, the feature such as simple to operate, easy to maintenance.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of vacuum test instrument, for detection of not allowing to use positive-pressure detection to reveal the leaks of the sealing medicine equipment of property.
The problem existing in order to solve prior art, the technical solution adopted in the utility model is:
Vacuum test instrument, include reduction valve, solenoid valve a, solenoid valve b, vacuum generator, three-way connection, pressure transducer, flow speed control valve, filtrator, test port, timer and hummer, described vacuum generator has two ports, and first port is that air intake opening passes through solenoid valve a, reduction valve connects pressurized air; One end that second port is vacuum port by three-way connection is connected with pressure transducer and hummer in turn, described pressure transducer is connected with pilot lamp with timer successively, and the other end of three-way connection connects product to be measured by solenoid valve b, flow speed control valve, filtrator, test port successively.
Advantage and effect that the utility model has are:
Vacuum generator of the present utility model is owing to having two ports, first port connects pressurized air, make second port of vacuum generator obtain vacuum pressure, again by the port of three-way connection Bonding pressure sensor and test products, by connecting test product, make product obtain vacuum test pressure, and and hummer, timer obtains pressure after setting the dwell time by pressure transducer and changes the result of determination that the electric signal sending embodies the product property revealed, therefore the sealing medical device product that can not allow to use positive-pressure detection leaks for detection of some is as got involved the leakage of foley's tube etc.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure: reduction valve 1, solenoid valve a2, solenoid valve b10, vacuum generator 3, three-way connection 4, pressure transducer 5, flow speed control valve 6, filtrator 7, test port 11, timer 8, hummer 9, test port 11, pilot lamp 12.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model vacuum test instrument, include reduction valve 1, solenoid valve a2, solenoid valve b10, vacuum generator 3, three-way connection 4, pressure transducer 5, flow speed control valve 6, filtrator 7, test port 11, timer 8 and hummer 9, described vacuum generator 3 has two ports, first port is air intake opening, and air intake opening connects pressurized air by solenoid valve a2, reduction valve 1; Solenoid valve a2 is connected with switch by circuit, and second port is vacuum port, and vacuum port is connected with three-way connection 4, and one end of three-way connection 4 is connected with pressure transducer 5 and hummer 9 in turn, and hummer is set test pressure lower than alarm pressure alarm for working as.Pressure transducer 5 is connected with pilot lamp 12 with timer 8 successively by circuit, and timer 8 is for the setting of dwell time.The other end of three-way connection 4 connects product to be measured by solenoid valve b10, flow speed control valve 6, filtrator 7, test port 11 successively, make product to be measured obtain the test pressure of setting, pressure transducer 5 is connected with solenoid valve b10 with after solenoid valve a2 parallel connection, through vacuumizing, pressurize, when pressure is during higher than alarm pressure, hummer can be reported to the police and with this, test products property revealed be judged.
Principle of work of the present utility model is as follows:
First port of vacuum generator connects compressed-air actuated port, make second port of vacuum generator obtain vacuum pressure, again by the port of three-way connection Bonding pressure sensor and test products, by connecting test product, make product obtain vacuum test pressure, and obtain pressure after setting the dwell time with hummer, timer by pressure transducer, change the result of determination that the electric signal sending embodies the product property revealed.
The course of work of the present utility model is as follows:
(1) air intake opening of vacuum generator 3 passes into pressurized air, by reduction valve 1 steady pressure, passes to normally closed solenoid valve a, b cut-off;
(2) set test pressure, alarm pressure, for example, set test pressure :-80Kpa, alarm pressure :-79Kpa, when product leakage 1Kpa pressure alarm;
(3) set the dwell time;
(4) product is connected to test port 11, presses switch, solenoid valve a, b open, and solenoid valve a controls and produces vacuum pressure, and test port gas pressure value is controlled in solenoid valve b switching;
(5) pressure transducer 5 shows current pressure, now timer 8 provides the time of a steady pressure, because product and pipeline have a constant volume, flow speed control valve 6 is used for controlling gas flow rate, be directly proportional to product volume, now pressure transducer can be controlled solenoid valve a, b, to pressure, reaches and sets test pressure solenoid valve a, b closure, now, solenoid valve b rear section will keep setting test pressure;
(6) timer 8 starts to calculate the dwell time, during this, if be greater than-79Kpa of pressure hummer can report to the police, if be greater than-79Kpa and to reach setting-up time pilot lamp 12 bright;
(7) unload product, pressure transducer 5 resets, and completes once test, so circulation.
