Description
Technical field
The present invention relates to rubber diaphragm air tightness test field, be related specifically to the rubber corrugated diaphragm used in level sensor and leak hunting.
background field
The air tightness test of rubber diaphragm is all complete manually in the market, the great effort of such action need cost staff, and test diaphragm time the time wayward, the time is easily caused to pass, cause test result not accurate enough, the leakage of diaphragm simultaneously also needs eye-observation, not easily judges the quality of diaphragm.
Summary of the invention
In order to solve the problem, the present invention proposes a kind of membrane leak detector, the time of testing can be controlled, be provided with diaphragm gas leakage autoalarm simultaneously, can also once test multiple diaphragm.
In order to reach the object of foregoing invention, the present invention proposes following scheme:
Membrane leak detector, it comprises abase frame, cylinder, clamping, instrument box, electromagnetic valve component and control knob assembly, described abase frame comprises fixed head, pillar, base plate and feet, feet support baseboard four angles, pillar, between fixed head and base plate, supports fixed head; Described cylinder and instrument box are loaded on fixed head side by side; clamping upper end connects cylinder; lower end is connected on base plate; be loaded on pillar side; electromagnetic valve component is connected on base plate; be loaded on the other side of pillar, control knob is assembled in below abase frame, the controller for electric consumption control cylinder in described instrument box and electromagnetic valve component.
Described clamping comprises cylinder, upper die and lower die, axle sleeve and guide shaft, and patrix upper end connects cylinder, is positioned at below fixed head; the corresponding patrix of counterdie is contained in substrate side; axle sleeve is positioned at the both sides of cylinder, and guide shaft one end is connected in patrix, and the other end runs through the axle sleeve on fixed head.
Described instrument box comprises 24V power supply, 5V power supply, control panel, pressure unit, controller, power switch, power light, time setting toggle switch, hummer and leakage alarm pilot lamp, and 24V power supply, 5V power supply, control panel are contained in instrument box; Pressure unit is positioned at instrument box, and be contained in tracheae loop, controller is loaded on panel upper left side, pressure unit and controller decomposition pressure measurement components; Hummer and leakage alarm pilot lamp are loaded on upper right side successively; Power light and time setting toggle switch are loaded in the middle of on the right side of panel successively, and power switch is loaded on panel lower right side.
Described electromagnetic valve component comprises air inlet electromagnetic valve, exhaust solenoid valve, eight solenoid valves that leak hunting, air inlet electromagnetic valve, exhaust solenoid valve are loaded on Liang Ge angle, substrate side respectively, eight solenoid valves that leak hunting are divided into two groups, and the 1-4# solenoid valve that leaks hunting is loaded on substrate, the side of pillar; The 5-8# solenoid valve that leaks hunting is loaded on above fixed head, is positioned at instrument box.
Described control knob assembly has three buttons and control panel, start button one, scram button and start button two, is loaded on the control panel of base plate lower end successively; Only have when start button one and start button two are pressed simultaneously, clamping ability matched moulds, ensure that handling safety, and when meeting unexpected generation, click scram button, clamping is thrown off.
Advantage of the present invention is that simplicity of design is compact, can arrange the time, and effectively control the test duration, the air tightness test of diaphragm is tested with instrument completely, effectively detect and do not need the diaphragm that impermeability is bad human eye ceaselessly to observe, alleviate worker workload, and this testing tool once can test eight diaphragms, enhances productivity.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.

Described instrument box 6 comprises 24V power supply, 5V power supply, control panel, pressure unit, controller 7, power switch 8, power light 9, time setting dial-up 10, hummer 11 and leakage alarm pilot lamp 12,24V power supply, 5V power supply, control panel and is contained in instrument box 6; Pressure unit is positioned at instrument box 6, and be contained in tracheae loop, controller 7 is loaded on panel upper left side, pressure unit and controller 7 decomposition pressure measurement components; Hummer 11 and leakage alarm pilot lamp 12 are loaded on upper right side successively; Power light 9 and time setting toggle switch 10 are loaded in the middle of on the right side of panel successively, and power switch 8 is loaded on panel lower right side.
Described electromagnetic valve component 17 comprises air inlet electromagnetic valve, exhaust solenoid valve, eight solenoid valves that leak hunting, air inlet electromagnetic valve, exhaust solenoid valve are loaded on Liang Ge angle, substrate side respectively, eight solenoid valves that leak hunting are divided into two groups, and the 1-4# solenoid valve that leaks hunting is loaded on substrate, the side of pillar; The 5-8# solenoid valve that leaks hunting is loaded on above fixed head, is positioned at instrument box.
Described control knob assembly has three buttons and control panel 18, start button 1, scram button 20 and start button 2 21, is loaded on the control panel 18 of base plate 4 lower end successively; Only have when start button 1 and start button 2 21 are pressed simultaneously, clamping ability matched moulds, ensure that handling safety.When meeting unexpected generation, click scram button 20, clamping is thrown off.
During test diaphragm; turn on the power switch 8; diaphragm to be measured is put in clamping; the test duration is set with toggle switch 10; then patrix 13 and counterdie 14 is promoted diaphragm seal in clamping by the programmed control cylinder 1 of design inside instrument box 6; electromagnetic valve component 17 then carries out air inlet, pressurize, exhaust according to default program to diaphragm; diaphragm is tested; test is to when having diaphragm impermeability defective; hummer 11 can be reported to the police, and simultaneously to demonstrate which diaphragm impermeability defective for leakage alarm pilot lamp 12.
