Description

Technical Field

[0001] The utility model relates to the field of pipeline installation, in particular to a butt joint mechanism for pipeline installation. Background Art

[0002] Some larger pipes are usually connected by flanges, bolts and nuts when they are connected. When connecting flanges, the flanges are welded on two pipes at different positions. When they are connected, the round holes between them need to be aligned so that bolts can be passed through for fixing. And when the round holes on the flanges are punched, the round holes on the two flanges may not completely overlap. This may cause the corresponding misalignment during the connection, making it impossible to pass the bolts normally, which will cause trouble for the installation connection. At the same time, when the water is disconnected or the valve is closed too quickly, due to the inertia of the pressure water flow, the water flow shock wave will form a water hammer line, which is like a hammer hitting the inner wall of the pipe. The force generated by the water flow shock wave back and forth is sometimes very large, which may cause the connection between the two pipes to loosen and cause water seepage. For this reason, we designed a connection mechanism for pipeline installation. Utility Model Content

[0003] In order to solve the technical problem that the misalignment of flange holes on two pipelines causes inconvenience in installation, the utility model provides a butt joint mechanism for pipeline installation.

[0004] The utility model is implemented by the following technical scheme: a butt joint mechanism for pipeline installation, comprising a butt joint pipeline, a vertical pipe designed vertically upward is welded in the middle of the butt joint pipeline, and an anti-surge valve is installed at the upper end of the vertical pipe;

[0005] Both left and right ends of the butt joint pipe are movably provided with connecting flanges, and four arc-shaped holes distributed in a ring are opened on the connecting flange. Both left and right ends of the butt joint pipe are connected to an external pipe through the connecting flanges.

[0006] As a further improvement of the above scheme, the docking pipe includes a horizontal pipe 1, and arc pipes are integrally formed on the left and right sides of the horizontal pipe 1, and horizontal pipe 2 arranged horizontally is integrally formed on the left and right sides of the arc pipe. The bending design of the docking pipe can reduce the impact of the water flow, thereby reducing the water hammer effect, improving the sealing of the docking pipe connection, and extending the service life.

[0007] As a further improvement of the above scheme, the arc tube includes a straight tube section, and the upper and lower sides of the straight tube end are integrally formed with 60-degree elbows, and the bending parts of the upper and lower 60-degree elbows are respectively thickened to form thickened part one and thickened part two. When water flows, it will impact the bending part of the arc tube, causing it to wear more seriously. Thickened part one and thickened part two are provided to thicken it, thereby increasing its impact resistance.

[0008] As a further improvement of the above scheme, the vertical pipe is welded to the horizontal pipe one of the docking pipe, the interior of the vertical pipe is connected with the interior of the horizontal pipe one, and the top end of the vertical pipe is above the horizontal pipe two on the left and right sides of the docking pipe. The liquid height inside the vertical pipe is not higher than the internal height of the two horizontal pipes two on the left and right sides, so that the normal use of the anti-surge valve will not be affected when the water flows normally.

[0009] As a further improvement of the above scheme, the outermost ends of the two horizontal pipes on the left and right sides of the docking pipe are welded with abutment rings, and the inner circle of the abutment ring is integrated with a plug-in tube. The inward side of the plug-in tube extends into the interior of the two horizontal pipes and is welded thereto, thereby improving the connection firmness between the plug-in tube and the docking pipe. The edges of the inner circles on both sides of the plug-in tube are chamfered to form an arc surface. The plug-in tube can be plugged into the interior of the pipe, thereby extending the connection between the pipe and the docking pipe, thereby improving the sealing performance. The design of the arc surface reduces the contact area between the water flow and the two ends of the plug-in tube, thereby reducing the impact force on the plug-in tube to a minimum, thereby extending its service life.

[0010] As a further improvement of the above solution, a flange is welded on the inner side of the pipe, the width of the arc-shaped hole on the connecting flange is consistent with the inner diameter of the circular hole on the flange, and the distribution positions of the two are the same.

[0011] As a further improvement of the above scheme, the connecting flange is movably sleeved on the horizontal pipe 2, and a contact groove is provided on the outward surface of the connecting flange. The depth of the contact groove is not greater than the thickness of the abutment ring, and the inner diameter of the contact groove matches the outer diameter of the abutment ring. When the connecting flange is connected to the flange by bolts, the abutment ring and the pipeline can be firmly pressed together, thereby improving the sealing performance.

[0012] As a further improvement of the above solution, a sealing gasket is tightly pressed between the connecting flange and the flange, and the sealing gasket is sleeved on the outer ring surface of the plug-in tube, thereby improving the sealing effect.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The two pipes of the utility model are connected by a butt pipe, and the left and right sides of the butt pipe are movably sleeved with connecting flanges, and the arc-shaped hole on the connecting flange is widened and designed to cooperate with the abutment ring, so that the arc-shaped hole on the connecting flange can be aligned with the circular hole on the flange and fixed through bolts, thereby improving the sealing effect;

[0015] The curved design of the docking pipe can reduce the impact of the water flow. Together with the anti-surge valve installed above the horizontal pipe of the docking pipe, when the valve in the pipe is closed, the anti-surge valve will quickly open and introduce the water flow in the pipe into the valve body, allowing it to expand freely, thereby eliminating the pressure wave in the pipe, reducing the water hammer effect and ensuring the sealing effect of the connection.

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example:

[0024] Please combine Figure 1-Figure 4 A butt joint mechanism for pipeline installation in this embodiment includes a butt joint pipeline 1, a vertical pipe 2 designed to be vertically upward is welded in the middle of the butt joint pipeline 1, and an anti-surge valve 3 is installed at the upper end of the vertical pipe 2;

[0025] Both left and right ends of the butt joint pipe 1 are movably mounted with connecting flanges 4 , on which four circularly distributed arc holes 41 are opened. Both left and right ends of the butt joint pipe 1 are connected to an external pipe 5 through the connecting flanges 4 .

[0026] The docking pipe 1 includes a horizontal pipe 11, and the left and right sides of the horizontal pipe 11 are integrally formed with an arc pipe 12, and the left and right sides of the arc pipe 12 are integrally formed with a horizontally arranged horizontal pipe 2 13. The bending design of the docking pipe 1 can reduce the impact of the water flow, thereby reducing the water hammer effect, improving the sealing of the connection of the docking pipe 1, and extending the service life.

[0027] The arc tube 12 includes a straight tube section, and the upper and lower sides of the straight tube end are integrally formed with 60-degree elbows, and the bending parts of the upper and lower 60-degree elbows are respectively thickened to form a thickened portion 121 and a thickened portion 122. When the water flows, it will impact the bending part of the arc tube 12, causing it to wear more seriously. The thickened portion 121 and the thickened portion 122 are provided to thicken it and increase its impact resistance.

[0028] The vertical pipe 2 is welded to the horizontal pipe 11 of the docking pipe. The interior of the vertical pipe 2 is connected to the interior of the horizontal pipe 11, and the top of the vertical pipe 2 is above the horizontal pipe 2 13 on the left and right sides of the docking pipe 1. The liquid height inside the vertical pipe 2 is not higher than the interior height of the two horizontal pipes 13 on the left and right sides, so that the normal use of the anti-surge valve 3 will not be affected when the water flows normally.

[0029] The outermost ends of the horizontal pipes 13 on the left and right sides of the docking pipe 1 are welded with abutment rings 6, and the inner circle of the abutment ring 6 is integrated with a plug-in tube 7. The inward side of the plug-in tube 7 extends into the interior of the horizontal pipe 13 and is welded thereto, thereby improving the connection firmness between the plug-in tube 7 and the docking pipe 1. The inner circle edges on both sides of the plug-in tube 7 are chamfered to form an arc surface 71. The plug-in tube 7 can be plugged into the interior of the pipe 5, thereby extending the connection between the pipe 5 and the docking pipe 1, thereby improving the sealing performance. The design of the arc surface 71 reduces the contact area between the water flow and the two ends of the plug-in tube 7, thereby reducing the impact force on the plug-in tube 7 to a minimum, thereby extending its service life.

[0030] A flange is welded on the inner side of the pipe 5 , and the width of the arc-shaped hole 41 on the connecting flange 4 is consistent with the inner diameter of the circular hole on the flange, and the two are distributed at the same position.

[0031] The connecting flange 4 is movably sleeved on the horizontal pipe 13, and a contact groove 42 is provided on the outward surface of the connecting flange 4. The depth of the contact groove 42 is not greater than the thickness of the abutment ring 6, and the inner diameter of the contact groove 42 matches the outer diameter of the abutment ring 6. When the connecting flange 4 is connected to the flange by bolts, the abutment ring 6 and the pipeline 5 can be firmly pressed together, thereby improving the sealing performance.

[0032] A sealing gasket is tightly pressed between the connecting flange 4 and the flange, and the sealing gasket is sleeved on the outer ring surface of the plug-in tube 7, thereby improving the sealing effect.

[0033] The implementation principle of a docking mechanism for installing a pipe 5 in the embodiment of the present application is as follows: when docking two pipes 5, the two pipes 5 are connected to the horizontal pipes 13 at both ends of the docking pipe 1 respectively. Specifically, since the connecting flange 4 is directly movably sleeved on the horizontal pipe 13, it can be rotated arbitrarily, and the arc hole 41 on the connecting flange 4 is widened, so that the arc hole 41 on the connecting flange 4 can be aligned with the circular hole on the flange and fixed through bolts;

[0034] The docking pipe 1 is designed to be curved to reduce the impact of the water flow, and an anti-surge valve 3 is arranged above the horizontal pipe 11 of the docking pipe 1. When the valve in the pipe 5 is closed, the anti-surge valve 3 will open quickly and introduce the water flow in the pipe 5 into the valve body, allowing it to expand freely, thereby eliminating the pressure wave in the pipe 5. Once the pressure wave in the pipe 5 is eliminated, the anti-surge valve 3 will close quickly, thereby ensuring the normal working state of the pipe 5, which can reduce the water hammer effect and ensure the sealing effect of the connection;

[0035] The two pipes 5 are connected by a butt pipe 1, and the left and right sides of the butt pipe 1 are movably sleeved with a connecting flange 4, and the arc hole 41 on the connecting flange 4 is widened and designed to cooperate with the abutment ring 6, so that the arc hole 41 on the connecting flange 4 can be aligned with the circular hole on the flange and fixed through bolts, thereby improving the sealing effect;

[0036] The curved design of the docking pipe 1 can reduce the impact of the water flow. In combination with the anti-surge valve 3 arranged above the horizontal pipe 11 of the docking pipe 1, when the valve in the pipe 5 is closed, the anti-surge valve 3 will quickly open and introduce the water flow in the pipe 5 into the valve body, allowing it to expand freely, thereby eliminating the pressure wave in the pipe 5, reducing the water hammer effect, and ensuring the sealing effect of the connection.

[0037] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
