Description

Technical Field

[0001] The utility model relates to the field of pipeline joints, in particular to an air expansion type pipeline quick sealing joint. Background Art

[0002] Pipe joints are a type of component used to connect pipes. Pipe joints can be divided into threaded joints, flange joints, etc. according to the way they are used. For pipe joints that are not prefabricated with threads or flange joints, the pipe can be fixed to the outside of the joint with a pipe clamp or inserted into the inside for use. For hole-shaped joints, the pipe can only be inserted into the hole-shaped joint for use. At this time, the sealing may be poor. If the inner wall of the connected pipe mouth is corroded and causes an uneven surface, the sealing will be more serious. Therefore, we propose a new type of pipe quick sealing joint. Utility Model Content

[0003] In view of the problems existing in the existing technical solutions, the purpose of the utility model is to provide an inflatable pipeline quick sealing joint.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A pneumatic pipeline quick sealing joint comprises a main body, wherein the main body comprises an insertion end, an output end and a limiting ring, wherein the limiting ring is located between the insertion end and the output end, wherein the insertion end is provided with a sealing ring groove, wherein an inflatable sealing ring is provided in the sealing ring groove, wherein the inflatable sealing ring is provided with an inflation nozzle, and wherein the inflation nozzle passes through the limiting ring.

[0006] Furthermore, the insertion end, the output end and the limiting ring are integrally formed.

[0007] Furthermore, the inflatable sealing ring is made of rubber, and the height change value after inflation is 0mm-8mm.

[0008] Compared with the prior art, the utility model has the following beneficial effects: after the inflatable pipeline quick sealing joint of the utility model is inserted into the pipe mouth to be connected, the inflatable sealing ring is inflated through the inflation and exhaust nozzle using an inflating pump or a gas cylinder and the like, and the inflatable sealing ring expands, and a sealing surface can be formed between the inner wall of the pipe mouth and the joint regardless of whether the inner wall of the pipe is smooth, so that the fluid in the pipe will not flow out of the socket. After use, the gas in the inflatable sealing ring is released through the inflation and exhaust nozzle, and the joint can be quickly pulled out; the joint has low requirements on the style of the pipe joint to be connected, and has a simple structure and low cost.

[0009] Figure 1 The present invention is a schematic structural diagram of an inflatable pipeline quick sealing joint according to an embodiment of the present invention.

[0010] Figure 2 Schematic diagram of the body structure of an inflatable pipeline quick sealing joint according to an embodiment of the present invention.

[0012] In the figure: 1 - body, 2 - insertion end, 3 - output end, 4 - limit ring, 5 - sealing ring groove, 6 - inflatable sealing ring, 7 - air charging and discharging nozzle. Specific embodiments

[0013] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0014] Embodiment 1:

[0015] As Figures 1-3 shown, this embodiment provides an inflatable pipeline quick sealing joint, including a body (1), characterized in that: the body (1) includes an insertion end (2), an output end (3) and a limit ring (4), the limit ring (4) is located between the insertion end (2) and the output end (3), the insertion end (2) is provided with a sealing ring groove (5), an inflatable sealing ring (6) is arranged in the sealing ring groove (5), the inflatable sealing ring is provided with an air charging and discharging nozzle (7), a hole corresponding to the outer diameter of the air charging and discharging nozzle (7) is arranged on the limit ring (4), and the air charging and discharging nozzle (7) passes through the limit ring (4).

[0016] Specifically, the insertion end (2), the output end (3) and the limit ring (4) are integrally formed.

[0017] Specifically, the material of the inflatable sealing ring (6) is rubber, and the height change value after inflation is 0 mm - 8 mm.

[0018] In use, the output end (3) of the body (1) is connected to an output pipe, and various fixing methods such as pipe clamp fixing and thread fixing can be adopted for fixing, mainly depending on the form of the output end (3). After the body (1) is inserted into the pipe orifice of the pipe to be connected, an inflation device such as an air pump is used to inflate the inflation sealing ring through the air charging and discharging nozzle. The inflation sealing ring will expand, and a sealing surface can be formed between the inner wall of the pipe orifice and the joint regardless of whether the inner wall of the pipeline is smooth. In this way, the fluid in the pipe will not flow out from the socket. Since the inflation sealing ring is made of rubber material, a good sealing effect can be formed even if the inner wall of the pipeline is not smooth. If a small amount of fluid leaks out, the sealing performance can be further improved by increasing the pressure of the gas in the inflation sealing ring. At the same time, after the inflation sealing ring is inflated with gas, the quick connector of this pipeline can thus adapt to a pipe orifice slightly larger in diameter than the output end of the body, improving the adaptability of the quick connector of the pipeline.

[0019] After use, the gas in the inflation sealing ring is released through the air charging and discharging nozzle, and the joint can be quickly pulled out.

[0020] The above content is only an illustrative example of the structure of the present utility model. Those skilled in the art of this technology can make various modifications, supplements or substitutions in a similar way to the described specific embodiments, as long as they do not deviate from the structure of the present utility model or exceed the scope defined by this claim book, they shall fall within the protection scope of the present utility model.
