The device comprises a movable constant pressure adjustable component, a combined gas dosing tube, a displacement sensor, an arithmetic displaying alarm system, etc. As shown by the figure, the utility model comprises a base (1), a steel jacket (2), a measuring tube (3), an annlus (4), an air tube (5), a bracket (6), a constraining piece (7), a measuring head (8), an electric vortex flow displacement sensor (9), a flange (10), a gas outlet valve (11), a gas inlet valve (12), a sphygmomanometer (13) and an arithmetic displaying alarm system (14).
Description
The utility model is about form the device that detects even part micro-leakage with buret.This device can directly detect fast under constant voltage and leak value below 10 millimeters/minute, and pressure is at 250～1000mmH
2The even part of O scope is specially adapted to detect the micro-leakage value that pin cuts down in the automobile carburetor.
The detection of mating plate micro-leakage value, many now employing burets are formed various pick-up units.Though principle is similar, but the pick-up unit of being formed can adapt to few, the Chongqing machine of industrial batch fast detecting and grind the reason iron that declines and give birth to comrade and designed a kind of " combination soap-film sniffer " in 1986, and in Chongqing City's packing association annual meeting in Dec then written delivering.In this sniffer, graduated buret is contained on the rotor, the collection type interface communicates with the leak detection body of thermometer, pressure reduction U-shaped pipe and rotor bottom through the four-way adapter glass, there is a liquid soap rubber pocket leak detection body lower end, the gas that detected pieces is leaked, import in the buret by soap-film, range estimation buret scale value, pressure difference and temperature and time are used formula q
nDry gas volumetric leak value when=V (Tn(Ps-Pp))/(TsPnt) calculating standard state (temperature T n, pressure P n).This device, though structure is simpler, laboratory and scene are all available.But batch detection is very time-consuming in the industry, and accuracy directly is subjected to soap lye concentration and range estimation error effect, and structure disperses to owe reasonable.
The purpose of this utility model is that design is a kind of simple in structure, and compact in design is reasonable, does not have the gas leakage detector that leaks and can directly detect even part micro-leakage fast under constant voltage, this leak locator has the U-shaped pipe, the aerometer buret, detected pieces interface, computing display alarm system and closed shell.Its middle shell is made up of support, steel bushing, support, there is the tracheae of a connection support at center, steel bushing hole, measuring head, ring sleeve and buret axially are unified into a mobile adjustable constant voltage assembly, this assembly is enclosed within and just constitutes the airtight composition gas gauge line of mercury between tracheae and the steel bushing, the straight-through sphygmomanometer of this pipe, UNICOM of computing display alarm system electricity vortex flow displacement transducer.Above-mentioned gas leakage detector has overcome the weakness that prior art exists.
Accompanying drawing is described out an embodiment of the present utility model.
With reference to the accompanying drawings, housing is a subassembly, is made up of support (1), steel bushing (2) and support (6).There is the tracheae (5) of a connection support (1) at steel bushing (2) center, hole.The adjustable constant voltage assembly that moves is joined together through special processing vertically by measuring head (8), ring sleeve (4) and buret (3), and measuring head (8) is a dish type copper spare, and there are two different through hole cylinders the dish both sides.Adjustable constant voltage assembly is enclosed between tracheae (5) and the steel bushing (2) and keeps certain intervals, and ring-type U-shaped pipe and the interior bore portion of ring-shaped sleeve (4) be made up of with steel bushing (2) buret (3) constitute the airtight composition gas gauge line of mercury.The straight-through sphygmomanometer (13) of this pipe, amount of mercury is determined by the metering stroke in the pipe.Support (6) is by the fixing electric vortex flow displacement transducer (9) of ring flange (10), and this sensor inlet end is equipped with attaching means (7), and adjustable constant voltage assembly inserts wherein through attaching means (7).Form computing display alarm system (14) by computing machine, digital indicator and acoustic-optic alarm, this UNICOM of system electricity vortex flow displacement transducer (9).Air inlet is cut down (12) and is given vent to anger that to cut down (11) be special in cutting down, and communicates with tracheae (5) respectively.Air inlet is cut down (12) and is linked with leather bag.The amount of mercury that changes in the adjustable constant voltage assembly realizes detecting pressure at 250～1000mmH
2The adjustment of O scope, and adjustable constant voltage assembly is provided with 1 milliliter, 4 milliliters, 10 milliliters three kinds metering specifications for selecting for use.This leak locator is provided with 15 seconds, 30 seconds and 60 seconds three kinds of leakage values demonstration times, when the detected pieces of loading onto if leakage arranged, the airtight interior gas volume of composition gas gauge line of mercury changes under constant voltage, adjustable constant voltage assembly is floating downwards the moving of attaching means (7) restriction lower edge axis, detect through electric vortex flow displacement transducer (9), computing machine is handled rapidly, demonstrates the leakage value in the demonstration time of setting, and unacceptable product is gone out by sound and light alarm Pick.
The major advantage of this leak detector is summarized as follows:
1. simple in structure, novel, compact in design is reasonable.
2. the main point of attachment of member has leak free characteristics through closed processes.
3. sealing fluid is a mercury, does not contain air, and dissolved air does not adhere to tube wall.
4. the Measuring and testing process is that adjustable constant voltage assembly is subjected to floating approximately moving process along axis, so the friction link is few, resistance is little, and servo-actuated is good, and decides the interior small buoyancy effect of stroke among a small circle by the computing machine correction.
5. detecting pressure can be at 250～1000mmH
2Adjust arbitrarily in the O scope.
6. calculate gas volume and change, adopt electric vortex flow displacement transducer, the displacement that the energy accurate recording is 0.05 millimeter, accuracy in detection height.
7. this leak locator is swift in response, and can occur reflection in 1～2 second, mixes Computing, realizes fast detecting in setting-up time.
8. the pressure values in the airtight composition gas gauge line of mercury can be by the sphygmomanometer Direct observation.
9. supply gas with leather bag, do not need to establish in addition compressed air source.
10. this leak locator is easy to operate, and defective device is gone out by sound and light alarm Pick.
