[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Embodiment 1:

[0028] Reference Figure 1-Figure 4, a condenser leakage detection device, comprising:

[0029] Detection kit 2;

[0030] The first capsule 3 is fixedly connected to the detection sleeve 2;

[0031] The second capsule 4 is fixedly connected to the detection sleeve 2;

[0033] A pressure valve is provided in the spray pipe 401;

[0034] Insert the condenser body 1 into the detection sleeve 2, place the connecting flange 101 in the detection sleeve 2, inflate the first bladder 3 and press against the condenser body 1, and pressurize the second bladder 4. When there is a leak at the connecting flange 101, the second bladder 4 deforms and sprays the material onto the condenser body 1 through the spray pipe 401.

[0035] An air supply pipe 202 is fixedly connected to the detection sleeve 2 , and the air supply pipe 202 is communicated with the first capsule 3 .

[0036] The air supply pipe 202 is connected to an external air supply pump and is used to inflate the first bladder 3 .

[0038] The pressurizing tube 203 is connected to an external pressurizing air pump and is used to increase the pressure in the second bladder 4 .

[0039] An exhaust pipe 205 is fixedly connected to the detection sleeve 2 , and the exhaust pipe 205 is communicated with the first capsule 3 .

[0040] A pressure relief valve is provided on the exhaust pipe 205. When the detection is completed, the pressure relief valve is opened, and the gas in the first capsule 3 is discharged through the exhaust pipe 205, and the detection sleeve 2 can be drawn out.

[0041] A material delivery pipe 204 is fixedly connected to the detection sleeve 2 , and the material delivery pipe 204 is communicated with the second capsule 4 .

[0042] The feed pipe 204 is connected to an external feed pump and is used to add marking pigment to the second capsule 4 .

[0043] Reference Figure 1-Figure 4During the inspection, the staff will align the inspection sleeve 2 with the connecting flange 101, and after placing the connecting flange 101 in the inspection sleeve 2, inflate the first bladder 3 through the gas pipe 202. At this time, the first bladder 3 will be inflated and bulged. The inflated first bladder 3 will be tightly against the condenser body 1. At this time, a sealed cavity is formed in the inspection sleeve 2. At this time, the second bladder 4 is supplemented with air and pressurized through the pressure pipe 203. At this time, the pressure in the second bladder 4 will increase;

[0044] When the pressure in the second bladder 4 just reaches the threshold of the pressure valve on the injection pipe 401, stop replenishing air into the second bladder 4. After standing for a period of time, the first bladder 3 is deflated. At this time, the detection sleeve 2 is pulled out to observe whether there is a pigment mark on the condenser body 1.

[0045] When the connecting flange 101 leaks, the leaked gas will enter the sealed cavity. The pressure in the sealed cavity will increase, and the second capsule 4 will be deformed under pressure. The pressure inside the second capsule 4 will increase, and the pressure valve on the spray pipe 401 will open. The pigment water stored in the second capsule 4 will be sprayed onto the condenser body 1 through the spray pipe 401, thereby completing the leakage marking.

[0046] The utility model sets a sealing cavity at the connecting flange 101 through the detection sleeve 2, and applies pressure to the sealing cavity by utilizing the gas during leakage, thereby squeezing out the marking pigment in the second capsule 4, thereby facilitating the staff to judge the leakage situation at the connecting flange 101, facilitating subsequent maintenance, and improving the detection efficiency.
