Description

Technical Field

[0001] The utility model belongs to the technical field of ship boiler detection, and in particular relates to a device for finding the leakage position of a boiler tube. Background Art

[0002] Whether a ship is repaired and shipped out of the factory depends mainly on whether the boiler can provide energy for the ship. Therefore, every time a ship enters the factory for repair, in order to ensure the safety and stability of the boiler, the boiler body must be pressure tested to determine whether the boiler tube is intact and to check for leakage in the boiler tube.

[0003] Boiler tube leak detection is generally done by water pressure. There are many boiler tubes in a boiler, usually hundreds or thousands of boiler tubes. In the case of boiler tube leakage, it is difficult to locate the water pipe leak detection and it takes a long time. When there is a boiler tube that has burned through, the boiler tube will leak after water pressure detection. The water will spread to other boiler tubes near the boiler tube and soak the other boiler tubes. It is impossible to accurately identify the actual leaking boiler tube during leak detection. Due to the particularity and limitations of boiler tube pressure testing, it is impossible to inspect and troubleshoot the soaked boiler tubes one by one, so it is impossible to determine the exact location of a single leaking boiler tube. The traditional treatment method is to seal or replace all soaked boiler tubes, but this method is time-consuming and inefficient, and there may even be a phenomenon that the boiler tube is blocked incorrectly.

[0030] like Figure 8 As shown, a schematic diagram of a boiler in a ship, wherein the boiler has a plurality of boiler tubes 3. A device for finding the position of boiler tube leakage is used to accurately detect which boiler tube 3 is leaking and repair it.

[0031] like Figure 1-7 As shown, a device for finding the leakage position of a boiler tube comprises:

[0032] The detection component is inserted into one end of the boiler tube 3, and includes a detection member 11, a first sealing ring 12, a first pressing member 13 and a first fastener 14; the detection member 11 is sequentially connected with a first cylindrical head 111, a first connecting portion 112 and a first threaded portion 113, the diameters of the first cylindrical head 111, the first connecting portion 112 and the first threaded portion 113 decrease in sequence, and a through hole 114 is provided in the axial center of the detection member 11; the first sealing ring 12 and the first pressing member 13 are sleeved on the first connecting portion 112, the first sealing ring 12 contacts with the end of the first cylindrical head 111, the outer diameter of the first sealing ring 12 contacts with the inner wall of the boiler tube 3, and the first fastener 14 is sleeved on the first threaded portion 113 and abuts against the first pressing member 13;

[0033] The plugging component is inserted into the other end of the boiler tube 3, and includes a plugging component 21, a second sealing ring 22, a second pressing piece 23 and a second fastener 24; the plugging component 21 is sequentially connected with a second cylindrical head 211, a second connecting portion 212 and a second threaded portion 213, and the diameters of the second cylindrical head 211, the second connecting portion 212 and the second threaded portion 213 decrease in sequence; the second sealing ring 22 and the second pressing piece 23 are sleeved on the second connecting portion 212, the second sealing ring 22 contacts the end of the second cylindrical head 211, the outer diameter of the second sealing ring 22 contacts the inner wall of the boiler tube 3, and the second fastener 24 is sleeved on the second threaded portion 213 and abuts against the second pressing piece 23.

[0034] In this embodiment, the sizes of the first cylindrical head 111 and the second cylindrical head 211, the first connecting portion 112 and the second connecting portion 212, the first threaded portion 113 and the second connecting portion 212, the first sealing ring 12 and the second sealing ring 22, the first pressing piece 13 and the second pressing piece 23, and the first fastener 14 and the second pressing piece 23 are consistent.

[0035] Among them, Figure 2 As shown, the manufacturing process of the detection member 11 is as follows: prepare a piece of iron rod, process a step position at one end of the iron rod as the first cylindrical head 111, a straight position as the first connecting part 112, and process the remaining iron rod into an M20 screw as the first threaded part 113, and process a through hole 114 in the center of the screw as a pressure test port for passing an air pipe or a liquid pipe to measure pressure changes. Figure 3 As shown, the processing of the blocking member 21 and the detection member 11 is similar, the difference being that the blocking member 21 does not have the through hole 114 .

[0036] like Figure 4 As shown, the first sealing ring 12 and the second sealing ring 22 are type sealing rings, which are sleeved on the first connecting portion 112 or the second connecting portion 212 and abut against the first cylindrical head 111 or the second cylindrical head 211. The first sealing ring 12 and the second sealing ring 22 are made of silicone.

[0037] like Figure 5 As shown, the processing and manufacturing process of the first pressing piece 13 or the second pressing piece 23 is as follows: prepare a section of iron rod, process a straight position for tightening the first sealing ring 12 or the second sealing ring 22, process a step position for tightening the first fastener 14 or the second fastener 24, and process a channel in the center for sleeved on the first connecting part 112 of the detection piece 11 or the second connecting part 212 of the blocking piece 21.

[0038] like Figure 6 As shown, the first fastener 14 or the second fastener 24 is a nut matched with the first threaded portion 113 or the second threaded portion 213 .

[0039] In other embodiments, Figure 7 As shown, the first washer 15 and the second washer 25 are also included; the first washer 15 is arranged between the first fastener 14 and the first pressing member 13, and the second washer 25 is arranged between the second fastener 24 and the second pressing member 23. The first washer 15 and the second washer 25 are flat washers, which are used to stably connect the first fastener 14 and the first threaded portion 113 or the second fastener 24 and the second threaded portion 213.

[0040] In this embodiment, a pressure gauge is also included, and the pressure gauge is connected to the detection component 11. The pressure gauge is an air pressure gauge or a water pressure gauge. Specifically, the detection component and the blocking component are used together and inserted into both ends of the boiler tube 3 respectively, and the air pressure or water pressure change of the boiler tube 3 is detected to determine whether there is a leak.

[0041] A device for finding the position of boiler tube leakage is used to accurately detect which boiler tube 3 is leaking. Figure 1 The connection method and detection method are as follows:

[0042] The detection member 11 is inserted into one end or the top end of the boiler tube 3, the through hole 114 is inserted into the hose of the inflator or the water press, the hose branch is connected to the air pressure gauge or the water pressure gauge, the first fastener 14 pushes the first gasket 15, and the first pressing member 13 squeezes the first sealing ring 12, so that the first sealing ring 12 is deformed and expanded to fit tightly against the inner wall of the boiler tube 3, so as to meet the detection tightness requirements.

[0043] The plugging piece 21 is inserted into the other end or the bottom end of the boiler tube 3, and the second fastener 24 pushes the second gasket 25, and the first second pressing piece squeezes the second sealing ring 22, so that the second sealing ring 22 is deformed and expanded to fit tightly against the inner wall of the boiler tube 3, thereby meeting the detection tightness requirement.

[0044] Start the inflator or water pressurizer, inject air or water through the pressure test port to increase pressure, and observe the pressure gauge. When the pressure reaches the specified value, if the boiler tube 3 is intact, the pointer of the pressure gauge will maintain the specified pressure value and will not drop the pressure, which means that the boiler tube 3 currently being tested is intact. If the specified pressure value cannot be reached during the pressure test, or the pressure cannot be maintained after reaching the specified pressure value, it means that the boiler tube 3 currently being tested is damaged.

[0045] In order to quickly perform inspection and quickly locate the leaking boiler tube 3, multiple sets of inspection tools can be manufactured and carried out alternately in the area to be inspected to shorten the waiting process and reduce the idle time of intermediate disassembly after the inspection is completed.

[0046] A device for finding the leakage position of a boiler tube, inserting the detection component and the plugging component into the two ends of the boiler tube respectively, inserting the water flow or air flow pipeline into the through hole of the detection component, and detecting by the pressure gauge, can quickly locate the leaking pipeline, accurately determine the position of a single leaking boiler tube, and avoid the occurrence of misjudgment. It effectively provides the shipowner with a basis for repairing the boiler, improves the decision-making efficiency of boiler tube repair, replacement or plugging, greatly shortens the repair time of the ship, and also creates space for the debugging of various related equipment, wins time for the main engine test and various equipment operation debugging, and creates higher benefits for the shipowner.
