Description

Technical Field

[0001] The utility model relates to the technical field of special equipment detection, in particular to a leakage detection device. Background Art

[0002] Special equipment inspection is an important means to ensure the safe operation of special equipment. Special equipment refers to equipment and facilities that involve life safety and are relatively dangerous, such as boilers, pressure vessels (including gas cylinders), pressure pipelines, elevators, lifting machinery, passenger ropeways, large amusement facilities, and special motor vehicles within the site (factory).

[0003] Some special equipment requires gas transportation through pipelines, and the gas may be corrosive or polluting. When the pipeline is transporting gas, the gas may leak at the flange connection. Most existing leakage detection devices have relatively complex structures and cannot perform good individual detection on the flange connection. When a leak occurs, the leaked gas cannot be collected in time, which can easily cause air pollution. Utility Model Content

When the storage box needs to discharge gas, a delivery pipe can be installed at the exhaust port position, and then the valve can be opened to discharge the gas inside the storage box.

[0008] Preferably, one end of the upper splint and the lower splint are both provided with a groove, and the groove positions of one end of the upper splint and the lower splint are commonly connected with a hinge frame, so that the upper splint and the lower splint can be flipped open and the gap at the connection position of the upper splint and the lower splint is reduced.

[0009] Preferably, rubber protective pads are provided on both sides of the two flange ring grooves, and the rubber protective pads clamp the two sides of the flange ring, thereby reducing the gap at the connection position and reducing the volume of gas in the pipeline leaking to the outside.

[0020] like Figures 1 to 4As shown, the leakage detection device of this embodiment includes an upper splint 1, a lower splint 5 is hingedly installed on one side of the upper splint 1, and a pipe 6 is commonly connected between the upper splint 1 and the lower splint 5. The opposite ends of the upper splint 1 and the lower splint 5 are provided with flange ring grooves 13, and a plurality of holes 12 are provided at the middle positions of the two flange ring grooves 13. The interiors of the upper splint 1 and the lower splint 5 are both provided with cavities 16, and the two cavities 16 are respectively connected to the corresponding holes 12. One end of the upper splint 1 and the lower splint 5 is provided with a pressure sensor 10, and the detection end of the pressure sensor 10 extends to the interior of the cavity 16. The pressure sensor 10 contains a warning light. The specific model of the pressure sensor 10 needs to be a gas pressure sensor that can sense changes in air pressure, and can output the pressure to convert the pressure change into an electric current. When the flange ring at the connection position of the pipe 6 leaks, the gas inside the pipe 6 will pass through the hole 12 and enter the air Inside the cavity 16, the air inside the cavity 16 is squeezed. When the pressure inside the cavity 16 changes, the pressure sensor 10 will output a changing current to turn on the warning light. An electromagnetic valve connector 7 is provided on one side of the upper splint 1 and the lower splint 5. The electromagnetic valve contained in the electromagnetic valve connector 7 is electrically connected to the pressure sensor 10, and the electromagnetic valve is in a normally closed state. When a leak occurs, the pressure sensor 10 will send a signal to the electromagnetic valve after issuing an alarm, and the electromagnetic valve will open, so that the electromagnetic valve connector 7 is in a connected state. One end of the electromagnetic valve connector 7 extends to the inside of the cavity 16, and a hose 2 is provided at one end of the electromagnetic valve connector 7. A storage box 3 is provided at one end of each of the two hoses 2. When the electromagnetic valve connector 7 is in a connected state, the leaked gas will pass through the electromagnetic valve connector 7 through the hose 2 and flow into the storage box 3 for storage, thereby reducing the volume of gas inside the pipeline 6 leaking into the air.

[0021] Specifically, two upper hoops 4 are provided at the bottom end of one storage box 3, and two lower hoops 9 are provided at the top end of the other storage box 3. The upper hoops 4 are engaged with one end of the lower hoops 9. The upper hoops 4 and the lower hoops 9 are used together to fix the two storage boxes 3 so that the storage boxes 3 can store leaked gas.

[0022] Furthermore, one end of each storage box 3 is provided with an exhaust port 8, and the exhaust port 8 contains a valve. The valve is in a normally closed state, so that the interior of the storage box 3 is in a closed state. If a leak occurs, gas will enter the interior of the storage box 3. When the storage box 3 needs to discharge gas, a delivery pipe can be installed at the position of the exhaust port 8, and then the valve can be opened to discharge the gas inside the storage box 3.

[0023] Furthermore, a groove 14 is provided at one end of the upper splint 1 and the lower splint 5, and a hinge frame 15 is connected to the groove 14 at one end of the upper splint 1 and the lower splint 5, so that the upper splint 1 and the lower splint 5 can be flipped open and the gap at the connection position of the upper splint 1 and the lower splint 5 is reduced.

[0024] Furthermore, rubber protective pads 11 are provided on both sides of the two flange ring grooves 13. The rubber protective pads 11 clamp the two sides of the flange rings, reduce the gap at the connection position, and reduce the volume of gas in the pipeline 6 leaking to the outside.

[0025] Furthermore, the two sets of upper hoops 4 and lower hoops 9 are detachably mounted on the outer surface of the pipe 6 , and the upper hoops 4 and lower hoops 9 fix the two storage boxes 3 at predetermined positions to facilitate the collection of leaked gas.

[0026] The method of using this embodiment is as follows: when installing the leakage detection device, the flange ring grooves 13 opened at the opposite ends of the upper clamping plate 1 and the lower clamping plate 5 are aligned with the flange ring at the connection of the pipe 6 and installed. The upper clamping plate 1 and the lower clamping plate 5 tighten the circumferential surface of the flange ring so that the rubber protective pad 11 is located on both sides of the flange ring. Then, the two sets of upper hoops 4 and lower hoops 9 are clamped on the outer surface of the pipe 6. If the flange ring at the connection position of the pipe 6 leaks, the gas inside the pipe 6 will pass through the hole 12 and enter the cavity 16, causing the air inside the cavity 16 to be squeezed. When the pressure inside the cavity 16 changes, the pressure sensor 10 will output current to make the warning light light up. When a leak occurs, the pressure sensor 10 will send an alarm and send a signal to the solenoid valve. The solenoid valve opens, making the solenoid valve connector 7 in a connected state. The leaked gas will pass through the solenoid valve connector 7 through the hose 2 and flow into the storage box 3 for storage, thereby reducing the volume of gas inside the pipe 6 leaking into the air.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
