Description

Technical Field

[0001] The utility model relates to the technical field of glue injection and plugging, namely a glue injection tool for rapid and uninterrupted leak plugging. Background Art

[0002] In the prior art, the glue injection tool is composed of a manual hydraulic pump, a hydraulic conduit, a glue injection gun and a glue injection gun head assembly (such as Figure 2 ), inject and plug the leaking part. Under normal circumstances, in the process of leak plugging, a manual hydraulic pump, a glue gun, and a glue gun head are used to divide the glue stick into multiple points for glue injection to achieve the plugging effect. In the plugging process, the amount of glue injected at the first point is the key to plugging the leaking part. The glue injection at this point requires a large amount and needs to be injected quickly. After the first point is completed, the micro-leak point is combined with the internal pressure to perform a closed glue injection to achieve the purpose of no leakage and no seepage. In recent years, through the online pressure leakage plugging of running equipment, the main manifestations are: small diameter of the glue gun head, small injection amount, slow injection speed, low temperature blockage, intermittent injection leading to plugging failure and other reasons. The injection is interrupted, the injection amount is small, and the plugging glue stick cannot be continuously injected, which seriously threatens the personal safety of the operator; especially in the process of plugging toxic media, it is necessary to quickly plug to reduce the risk of toxic media to operators, and on the one hand, the occurrence of pollution accidents of toxic media to the surrounding environment after leakage.

[0003] In the past, glue injection tools had problems such as inability to continuously inject glue, gun head clogging, and small injection volume. Only monomer injection, small aperture, and intermittent injection cannot achieve the effect of rapid injection and leakage sealing, making it take a long time to seal the leaking part. If the leaking part cannot be quickly injected due to the internal pressure, it will be difficult to handle the leaking part. The operator will intermittently fill the glue stick and it will take several times to seal the leaking part. Even during the sealing process, the injection gun head will be clogged during the injection process, and the sealing will fail during the replacement process. In addition, through a large number of injection pressure plugging analysis, it was found that for the plugging of gas pipelines and water pipelines, especially in the blast furnace smelting process, in order to increase the smelting intensity, the blast furnace top pressure is generally above 0.25MPA. The blast furnace raw gas carries dust in the high-pressure gas, which causes greater wear on the pipeline, making it easy to wear and leak. The flushing of the leak point further aggravates the wear, and ultimately the leaking part cannot be sealed. Utility Model Content

[0004] The purpose of the utility model is to provide a fast and uninterrupted plugging glue injection tool to address the above-mentioned deficiencies. When plugging, the glue injection tool can be quickly injected to quickly plug the leaking part, eliminate the leakage fault in the first time, and ensure safe and stable production operation.

[0005] The technical solution of the utility model is: a glue injection tool for rapid and uninterrupted injection of plugging leaks, comprising a glue injection gun head, a glue injection gun, a pipeline and a manual hydraulic pump connected in sequence, characterized in that a tee is connected between the glue injection gun head and the glue injection gun, another port of the tee is connected to another set of glue injection guns, pipelines and a manual hydraulic pump; a stop valve is arranged on a section of the tee; and a backflow prevention stop valve is arranged on a section of the tee connected to the glue injection gun head.

[0006] The stop valve and the anti-backflow stop valve are screws screwed into the through section.

[0007] The advantages of the utility model are: 1. By introducing a three-way connection, the gun head can realize two-way glue injection, which can be injected quickly, avoiding the occurrence of accidents such as backflow leakage and injury caused by replacing the glue stick during the injection process. After the leakage caused by water, gas, and wind, it ensures that the leakage part is quickly blocked at the first time, ensuring the normal production stability of the enterprise and the safety of the personnel, and also reducing the labor intensity of the blocking personnel, and the problem of gun head blockage and inability to inject glue does not occur. 2. After installing a stop valve on the three-way connection, the two stop valves can not only control the amount of glue injected and the injection speed, but also effectively prevent the occurrence of plugging failure caused by the conversion of the glue injection gun and the backflow, and ensure that the micro-leakage after plugging will not occur again.

[0008] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a simplified structural diagram of the utility model.

[0010] Figure 2 This is a schematic diagram of the injection tool structure before improvement. DETAILED DESCRIPTION

[0011] See also Figure 1 , 2 The names of the parts are as follows: glue injection gun head 1, glue injection gun 2, pipeline 3, manual hydraulic pump 4, tee 5, stop valve 6, anti-backflow stop valve 7, pressure gauge 8.

[0012] See also Figure 1, a tool for rapid and uninterrupted injection and plugging of leaks, including a glue injection gun head 1, a glue injection gun 2, a pipeline 3 and a manual hydraulic pump 4 connected in sequence. A tee 5 is connected between the glue injection gun head 1 and the glue injection gun 2, and the other port of the tee 5 is connected to another set of glue injection guns 2, pipelines 3 and manual hydraulic pumps 4. There is a stop valve 6 on this section, which is a screw screwed into the section. Its purpose is to close one side of the injection channel during the glue injection conversion process to prevent backflow. There is an anti-backflow stop valve 7 on the section of the tee 5 connected to the glue injection gun head 1, which is a screw screwed into the section. After the injection and plugging are completed, the injected material flows out in the opposite direction under the action of pressure. A threaded anti-backflow stop valve 7 is installed in the middle part of the tee 5. After the plugging is completed, the anti-backflow stop valve 7 is closed to prevent leakage caused by injection backflow. After closing, the backflow phenomenon is effectively cut off. After the tee 5 is introduced, the glue injection gun head 1 is injected into a double channel.

[0013] The glue injection gun head 1 is 10 cm long, machined from high carbon steel, and is made of 24 cm in diameter. The internal channel is 1 cm, the upper part is the injection channel, and has a connecting thread.

[0014] In many practical applications, the leaking parts are quickly injected with glue as soon as possible, which greatly reduces the difficulty of plugging and avoids the plugging time being too long due to the replacement of plugging parts after the plugging injection fails. After the threaded stop valve is installed, the two stop valves can not only control the amount of glue injected and the injection speed, but also effectively prevent the plugging failure caused by the reverse flow of the glue injection gun, and ensure that the micro-leakage will not occur again after plugging.

[0015] The application of this device not only improves the injection speed and injection volume, but also can complete the rapid plugging of leaks in the first place, especially the injection volume at low temperatures. At the same time, rapid injection plugging reduces the unsafe factors caused by personnel plugging process. The threaded stop valve effectively prevents the occurrence of secondary leakage caused by backflow after plugging.

[0016] During the injection process, temperature changes also affect the amount of glue injected. The original single-body glue injection head has a small aperture. Under low temperature conditions, the glue stick has poor fluidity and often gets clogged. It is changed to a two-way glue injection gun head with a larger aperture, which allows continuous injection and effectively avoids the practical problem of gun head clogging and slow injection.

[0017] In the past, the single-way glue injection gun head was intermittent and could not achieve continuous filling. Its aperture was 4 cm. Depending on the hardness of the glue stick, the injection speed was 2 to 6 cm per second, and the injection volume was 23 grams per minute. The aperture of the two-way glue injection gun head is 10 cm, the injection speed is 5 to 15 cm per second, and the injection volume reaches 60 grams per minute.

[0018] The above description is only a specific implementation of the present utility model, and various examples do not constitute a limitation on the essential content of the present utility model.
