Description

Technical Field

[0001] The utility model relates to the technical field of leak-proof devices, in particular to a leak-proof device under pressure suitable for a plane wall. Background Art

[0002] The pipes or containers used in daily life involve many aspects such as production, transportation, and storage. As the use time increases, their flat walls may cause leaks due to various reasons.

[0003] When a leak occurs, it is necessary to promptly plug the leak. Existing plugging devices suitable for plane walls are roughly divided into three categories. The first category is an umbrella-type plugger, that is, an umbrella rod is inserted at the leak point and unfolded, and the umbrella canopy is pressed against the wall surface by the pressure of the plugging medium. This type of plugger is limited to the plane wall with large leaks, and it is impossible to effectively prevent the plugging medium from leaking or leaking less during the plugging process, especially when the plugging medium is corrosive or toxic, which is easy to cause injuries to people; the second category is a top pressure plugger, that is, a top pressure rod is used to support the top pressure The piece blocks the leak, and the force of the push rod and the plane wall is balanced by the vacuum force generated by the suction cup of the plugger support rod adsorbing the wall. This type of plugger takes up a large space, is prone to mechanical interference, and the vacuum force is weak, and cannot effectively balance the pressure required for the push rod to push the push piece to produce the plugging effect; the third type is a patch-type plugging piece, that is, a plugging piece is glued or welded on the pipe outside the leak. Among them, the adhesive plugging piece has low pressure-bearing capacity, is easy to debond, and is easy to cause secondary leakage, while the welded plugging piece is not suitable for too thin plane walls. Utility Model Content

[0004] The utility model aims to provide a pressure plugging device suitable for a plane wall to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme, which includes a sealing cylinder and a drill rod, wherein an air groove is provided on one side of the sealing cylinder, a flow groove is provided on the other side of the sealing cylinder, a plurality of threaded holes are provided at the bottom of the sealing cylinder, a suction cup is set at the bottom of the sealing cylinder through a plurality of countersunk bolts and a hollow bolt on the threaded hole, a through groove 1 is provided above the threaded hole with the hollow bolt, the through groove 1 is respectively communicated with the air groove and the threaded hole with the hollow bolt, a main hole is provided in the center of the sealing cylinder, a through groove 2 is also provided in the wall body of the sealing cylinder close to the flow groove, the through groove 2 is respectively communicated with the flow groove and the main hole, a pressure cover is provided on the top thread of the sealing cylinder, and the drill rod is movably arranged in the main hole through the pressure cover.

[0006] As a preferred embodiment of the utility model, a drill bit is detachably provided at the bottom of the drill rod, a plurality of limit holes are opened on the side wall of the drill rod above the drill bit, and a hollow plug is provided in each limit hole, a limit rod is movably provided in the hollow plug, a spring is sleeved on the outer side of the limit rod, and the spring is arranged between one end of the limit rod and the hollow plug, a thread one is provided on the outer wall of the drill rod away from the drill bit, a fastening nut and a lock nut are threaded on the thread one, an "o"-shaped sealing ring is provided on the inner wall of the drill rod, and a pressure rod is provided on the inner thread of the drill rod.

[0007] As a preferred embodiment of the utility model, the top of the pressure rod is provided with a cross pattern, and the side wall of the top of the pressure rod is provided with a second thread.

[0008] As a preferred embodiment of the utility model, a one-way negative pressure nozzle is provided in the air groove, and a ball valve is provided on the flow groove.

[0009] As a preferred embodiment of the present invention, an oil seal is provided on the inner wall of the sealing cylinder.

[0010] Compared with the prior art, the above technical solution of the utility model has the following beneficial technical effects:

[0011] 1. The utility model solves the limitation that the umbrella-type leak plugger is suitable for large leak points on the plane wall, and solves the problem of plugging medium flowing out during the plugging process. Compared with the umbrella-type leak plugger, the utility model has a simpler structure, is easier to control, and has higher reliability.

[0012] 2. The utility model utilizes a pressure rod to push out a limiting rod, and rotates a fastening nut to press against a gland threadedly connected to the sealing tube, so that the sealing tube and the plane wall seal more closely fit, thereby solving the problem that the top pressure type leak stopper cannot effectively balance the pressure required for the leak plugging effect after the top pressure rod presses against the top pressure plate due to weak vacuum force; at the same time, since the anti-loosening nut and the fastening nut brake each other, the problem that the fastening nut becomes loose due to vibration of the plane wall due to various factors, causing secondary leakage, is solved.

[0013] 3. The utility model can be applied to plane walls of different thicknesses, and is equally applicable to thin and thick walls, and has low requirements on the material of the plane wall. It is applicable to plane walls of almost any material, solving the problem that patch-type plugging pieces are easy to debond or are not applicable to thinner plane walls, and has a wider applicability.

[0014] 4. The utility model is small in size, not easy to cause mechanical interference, and has the characteristics of repeated use, and is suitable for popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS
