Abstract
The utility model relates to a positive pressure tester. The tester comprises a pressure reducing valve, a speed regulator valve, a solenoid valve, a T-junction, a pressure sensor, buzzer, a timer, an indicating lamp, a filter and a test port. One end of the pressure reducing valve is connected with high pure nitrogen. The other end of the pressure reducing valve is connected with the solenoid valve through the speed regulator valve. The solenoid valve is connected with the T-junction. One end of the T-junction is successively connected with the pressure sensor and the buzzer. The pressure sensor is successively connected with the timer and the indicating lamp. The pressure sensor is connected with the solenoid valve through a circuit. The other end of the T-junction is connected with a product to be tested through the filter and the test port. The positive pressure tester of the utility model is connected with the product to be tested through the test port. Through inflation and pressure maintaining, when pressure is lower than alarm pressure, the buzzer gives out an alarm and leakage determination is performed on the tested product according to the alarm. The positive pressure is used to detect pressure resistance and leakage performance of a sealing medical apparatus product.
Description
Technical field
The utility model relates to a kind of positive pressure tester.
Background technology
Because some sealing medical device product need be used positive-pressure detection resistance to pressure, leaks.Therefore, must a kind of normal 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 positive pressure tester by normal pressure test component resistance to pressure, leaks, for having working pressure requirement or leaking the product requiring.
The problem existing in order to solve prior art, the technical solution adopted in the utility model is:
Positive pressure tester, include reduction valve, flow speed control valve, solenoid valve, three-way connection, pressure transducer, hummer, timer, pilot lamp, filtrator and test port, one end of described reduction valve connects high pure nitrogen, the other end of reduction valve is connected with solenoid valve by flow speed control valve, solenoid valve connecting tee joint, one end of three-way connection is connected with pressure transducer and hummer in turn, described pressure transducer is connected with pilot lamp with timer successively, and pressure transducer is connected with solenoid valve by circuit; The other end of three-way connection is connected product to be measured with test port by filtrator.
Advantage and effect that the utility model has are:
The positive pressure tester of the utility model connects product to be measured by test port, through gas overcharging, and pressurize, when pressure is during lower than alarm pressure, hummer can be reported to the police and with this, test products property revealed be judged, realizes and uses the resistance to pressure of normal pressure to sealing medical device product, and leaks detects.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure: reduction valve 1, flow speed control valve 2, solenoid valve 3, three-way connection 4, filtrator 5, test port 6, pressure transducer 7, hummer 8, timer 9, pilot lamp 10.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the positive pressure tester of the utility model, include reduction valve 1, flow speed control valve 2, solenoid valve 3, three-way connection 4, pressure transducer 7, hummer 8, timer 9, pilot lamp 10, filtrator 5 and test port 6, the air intake opening of described reduction valve 1 connects high pure nitrogen, the other end of reduction valve 1 is connected with solenoid valve 3 by flow speed control valve 2, solenoid valve 3 connecting tee joints 4, one end of three-way connection 4 is connected with pressure transducer 7 and hummer 8 in turn, described pressure transducer 7 is connected with pilot lamp 10 with timer 9 successively, timer is for the setting of dwell time, pressure transducer 7 is connected with solenoid valve 3 by circuit, the other end of three-way connection 4 is connected product to be measured by filtrator 5 with test port 6.Test port 6 communicates with pressure transducer 7 by filtrator 5, three-way connection 4, and pressure transducer 7 connects hummer 8, and hummer 8 is for working as alarm pressure lower than set pressure alarm.Pressure transducer 7 is controlled the open and close of solenoid valve 3, makes product to be measured obtain set pressure.
Principle of work of the present utility model is as follows:
The air intake opening of reduction valve 1 connects high pure nitrogen, presses starting switch, and pressure transducer 7 is converted to electric signal by current production chamber pressure value, controls the open and close of solenoid valve 3, until actual pressure reaches set pressure, and closed electromagnetic valve.Reach after set pressure, pressure transducer sends electric signal and starts timer 9, sets the dwell time, and dwell time internal pressure is unchanged, illustrates that product do not reveal; Pressure decreased, pressure transducer 7 sends electric signal, starts hummer 8, prompting product leakage.
?specific works process of the present utility model is as follows:
(1) air intake opening passes into high pure nitrogen, by reduction valve 2, pressure is adjusted to a little more than setup pressure value, passes to solenoid valve 3;
(2) set test pressure, alarm pressure, for example test pressure: 1MPa, alarm pressure: 0.9MPa is when product leakage 0.1MPa pressure alarm;
(3) set the dwell time;
(4) pressure transducer 7 has certain distance with product cavity distal-most end, and flow speed control valve 2 is used for controlling and produces aeration speed, makes the pressure of detection more accurate;
(5) product is connected to test port 6, presses switch, solenoid valve 3 is opened;
(6) current pressure reaches 1MPa, and solenoid valve 3 cuts out, and rear section will keep set pressure, and now, timer 9 provides a time that keeps pressure;
(7) timer 9 starts to calculate the dwell time, during this, if pressure≤0.9MPa hummer can be reported to the police; If pressure > 0.9MPa and to reach setting-up time pilot lamp bright;
(8) unload product, pressure transducer 7 resets, and completes once test, so circulation.
Claims (1)
1. positive pressure tester, it is characterized in that: include reduction valve, flow speed control valve, solenoid valve, three-way connection, pressure transducer, hummer, timer, pilot lamp, filtrator and test port, one end of described reduction valve connects high pure nitrogen, the other end of reduction valve is connected with solenoid valve by flow speed control valve, solenoid valve connecting tee joint, one end of three-way connection is connected with pressure transducer and hummer in turn, described pressure transducer is connected with pilot lamp with timer successively by circuit, pressure transducer is connected with solenoid valve by circuit, the other end of pressure three-way connection is connected product to be measured with test port by filtrator.
