Abstract

The utility model discloses a water tank dry type leak detection device and is characterized in that the water tank dry type leak detection device comprises a detected piece work station and a standard piece work station, the detected piece work station and the standard piece work station are respectively connected with an inflation gas source via inflation valves, the pipeline of the inflation gas source is provided with a pressure sensor electrically connected with a pressure digital display meter, the connecting pipeline between the detected element work station and the standard element work station is provided with a differential pressure transformer electrically connected with a differential pressure digital display meter, and two deflation valves are respectively provided between thedifferential pressure transformer and the detected element work station and between the differential pressure transformer and the standard element work station. The water tank dry type leak detectiondevice can quickly detect the leak of detected water tank.

Description

A kind of water tank dry type leak test plant

[technical field]

The utility model relates to a kind of water tank leak test plant.

[background technology]

Existing water tank dry type leak test plant is hunted leak to general the employing separately of leak detection of water tank measured piece, does not have the standard component contrast, and both inconvenient, operation is trouble again.

[summary of the invention]

In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of water tank dry type leak test plant that can carry out the rapid and convenient leak detection to the water tank measured piece.

For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:

A kind of water tank dry type leak test plant, it is characterized in that: described water tank dry type leak test plant comprises measured piece station and standard component station, the measured piece station is connected source of inflation gas by gas filling valve respectively with the standard component station, on the source of inflation gas pipeline, be provided with pressure transducer, pressure transducer is electrically connected with the pressure digital displaying meter, connecting line between measured piece station and the standard component station is provided with differential pressure transmitter, differential pressure transmitter is electrically connected with the differential pressure digital displaying meter, is respectively equipped with air release on the connecting line of differential pressure transmitter and measured piece station and standard component station.Described gas filling valve and air release all adopt solenoid valve.

The utility model changes by the pressure reduction that produces in the dwell time between water tank measured piece and the standard component, give the differential pressure digital displaying meter by differential pressure transmitter with the pressure reduction that detects, if pressure reduction is greater than setting value, the differential pressure digital displaying meter sends alerting signal, show that measured piece is defective, if pressure reduction is less than setting value, it is qualified that the differential pressure digital displaying meter then shows, also have the bleed pressure of inflation directly accurately to show by the pressure digital displaying meter by pressure transducer, if charge pressure is defective, the pressure digital displaying meter can send alerting signal, and leak detection is very efficient and convenient thus at once; Simultaneously, gas filling valve and air release adopt solenoid valve, can control more easily.

[description of drawings]

The utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model

[embodiment]

Accompanying drawing has been represented the technical solution of the utility model and embodiment, further describes each relevant details and principle of work thereof of embodiment below more in conjunction with the accompanying drawings.

With reference to accompanying drawing 1, this water tank dry type leak test plant, comprise measured piece station 6 and standard component station 1, the measured piece station is connected source of inflation gas by the inflation solenoid valve 2 of reversal connection respectively with the standard component station, on the source of inflation gas pipeline, be provided with a total inflation solenoid valve 4, the endpiece of total inflation solenoid valve 4 is provided with a pressure transducer 5, pressure transducer 5 is electrically connected with pressure digital displaying meter 7, connecting line between measured piece station and the standard component station is provided with differential pressure transmitter 8, differential pressure transmitter 8 is electrically connected with differential pressure digital displaying meter 9, is respectively equipped with pressure-releasing electromagnetic valve 3 on the connecting line of differential pressure transmitter 8 and measured piece station 6 and standard component station 1.

The principle of work of this water tank dry type leak test plant is such: at first open total gas filling valve water tank standard component and measured piece are inflated (charge pressure 160Kpa simultaneously, the gas filling valve of reversal connection this moment is in open mode, air release is in closed condition), the time can be set (general 10 seconds); Next judge that in the inflationtime of setting, if inflate qualifiedly, then the gas filling valve of two reversal connections is closed, if inflate defectively, pressure transducer can be given pressure digital displaying meter alerting signal, and the pressure digital displaying meter can show defective warning; Detect at last, inflate qualified back 5 seconds (balance) differential pressure transmitters and begin to detect, in 30 seconds (time can be set), if pressure reduction is greater than setting value 0.02Kpa, the differential pressure digital displaying meter sends alerting signal, shows that measured piece is defective, otherwise, show that measured piece is qualified; Detection finishes, and presses air release, and air release is opened simultaneously to standard component and measured piece venting.
