Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts Every other embodiment obtained, fall within the protection scope of the utility model.

Embodiment

Referring to attached drawing 1, it is the structural schematic diagram of the gas leakage hunting apparatus of the utility model.As shown in Figure 1, gas leak detection Device includes gas source vessel 6, detection pipe, monitor station 3, sensing chamber and air pressure detection piece.

Search gas is accommodated in gas source vessel 6, optionally, the search gas is the ammonia with vapor.Gas source holds The side of device 6 is equipped with Bidirectional Air Valve 61, and for controlling the releasing and supplement of search gas, Bidirectional Air Valve 61 is arranged in detection pipe On, one end of detection pipe is connect with gas source vessel 6, and the other end is connect with monitor station 3；Air inlet there are four being set on monitor station 3 100, the end of each air inlet is equipped with the air inlet pipe 101 connecting with part to be checked, is equipped with isocon in monitor station 3, and described point Flow tube is connect with the air inlet pipe in the monitor station respectively, for search gas shunting to be delivered in air inlet pipe；It is examining The top of scaffold tower 3 is equipped with sensing chamber 10,20,30 and 40, and the sensing chamber is separated to form by jig plate 1 and the connection of spacer post 2, The upper and lower surface of each sensing chamber is covered with Test paper, and optionally, the Test paper can be pH test paper (referring to attached drawing 2) the aobvious red of color reaction will occur, when the pH test paper and the search gas contact, so as to pass through pH test paper On RED sector correctly find the position of leakage point；It is additionally provided in the lower part of monitor station 3 for controlling air inlet switch By part 4 and the knob 5 of control search gas flow velocity；Air pressure detection piece include pressure sensor 7 and air pressure leak detection unit 8, Pressure sensor 7 is arranged in the air inlet pipe in monitor station, and air pressure leak detection unit 8 connect with pressure sensor 7 and passes to pressure The leak detection signal of sensor 7 is analyzed and processed, when the pressure value in the part to be checked that shows of air pressure leak detection unit within a certain period of time It is unchanged or only an a small range float, i.e., it is believed that part to be checked be non-defective unit No leakage point.

When hunting leak using the gas leakage hunting apparatus to urine collection bag, urine collection bag is first placed in 10 detections interior and and air inlet Pipe 101 is connected, and the air inlet switch 4 of 3 lower part of Pen-down detection platform opens air inlet, opens air pressure detector again at this time (only first Needed when secondary detection), air pressure leak detection unit 8 is resetted, then, Bidirectional Air Valve 61 is opened, the ammonia of vapor will be mixed with It is charged into urine collection bag, the air pressure show value in observation air pressure leak detection unit 8, when search gas will be filled with, adjusting knob 5 makes it Gradually fully support 10 sensing chamber, after a period of time, the air pressure show value of observation air pressure leak detection unit 8, if the air pressure show value without Significant change is only floated in an a small range, it may be considered that the urine collection bag good seal No leakage point；If air pressure show value Variation is obvious, then it represents that the urine collection bag has leakage point, changes the circulating direction of Bidirectional Air Valve 61 at this time, and search gas flows back to gas source Container 6 closes air inlet, the pH test paper of urine collection bag and corresponding sensing chamber is removed, according to the red point on the pH test paper It can determine the leakage point position on urine collection bag.
