Description

Technical Field

[0001] The utility model belongs to the technical field of water pipe component connection, and specifically relates to a quick connection joint for a water supply pipeline. Background Technique

[0002] A water supply pipeline is a pipeline system used to transport water, and its main function is to provide domestic water, fire water, production water and other various specific waters required for buildings, public facilities, industrial enterprises, etc. Water supply pipelines are made of a variety of materials. Among them, plastic pipelines have been widely used in the water supply system due to their advantages such as not rusting, not scaling, not reducing the diameter, small fluid resistance, effectively reducing water supply energy consumption, and increasing the water supply volume at the water use point.

[0003] In the prior art, when it is necessary to replace the water supply pipeline connector, usually various methods such as threaded connection, welded connection, socket connection or flange connection are used to connect two water supply pipelines together. During long-term use and observation, it is found that when the water supply pipeline breaks, is damaged or needs emergency repair due to reasons, replacing the pipeline and quickly completing the temporary connection between the pipelines can ensure the continuity of water supply.

[0004] Therefore, the utility model provides a quick connection joint for a water supply pipeline. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve at least one problem proposed in the background technique, a quick connection joint for a water supply pipeline is proposed.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A quick-connection joint for a water supply pipe described in the present utility model includes a first pipe; a second pipe is provided in the middle of the side wall of the first pipe; the second pipe is sleeved outside the first pipe; an annular airbag is fixedly connected to the middle of the side wall of the first pipe; a gas delivery pipe is fixedly connected to the middle of the side wall of the annular airbag; the annular airbag and the gas delivery pipe are hollow and communicate with each other; a first airbag is fixedly connected to the middle of the side wall of the annular airbag; the first airbag is hollow and communicates with the annular airbag; a plurality of cavities are provided between the second pipe and the first airbag; a second airbag is fixedly connected to the middle of the side wall of the first airbag; the second airbag is arranged in a funnel-shaped structure; the second airbag is hollow and communicates with the first airbag; In this step, by setting the annular airbag and the gas delivery pipe, the temporary connection between the first pipe and the second pipe can be quickly completed. When the second pipe is accidentally broken, damaged or needs emergency repair, in order to maintain the continuity of water supply or prevent waste of water resources, the annular airbag can be used to temporarily connect the first pipe and the second pipe to form a temporary closed system for component replacement work. By setting the first airbag and the cavities, the uneven structure can be used to better fit the uneven parts of the inner wall of the second pipe, forming a tighter fit, thereby reducing the risk of leakage. At the same time, the uneven design can play a role in physical locking to prevent the connection between the first pipe and the second pipe from loosening or shifting due to external forces. By setting the second airbag, the water flow can be quickly guided into the second pipe, reducing the residence time of the water flow on the inner wall of the second pipe, thereby keeping the second pipe unobstructed.

[0007] Preferably, an annular notch is provided in the middle of the side wall of the first pipe; an annular hard board is fixedly connected to the inner side wall of the annular notch; the annular hard board is made of a rigid material; In this step, by setting the annular notch and the annular hard board, the deformation of the end of the first pipe when being squeezed by the annular airbag, the first airbag and the second airbag can be reduced, so as to prevent the second pipe from being completely blocked from the inside, resulting in the situation that the first pipe cannot supply water into the second pipe.

[0008] Preferably, a fixing plate is fixedly connected to the middle of the side wall of the first pipe; a waterproof cloth is fixedly connected to the middle of the side wall of the fixing plate; the waterproof cloth covers the connection between the first pipe and the second pipe; the waterproof cloth is made of an elastic material; In this step, by setting the waterproof cloth with excellent waterproof performance, it can be closely attached to the connection between the first pipe and the second pipe to form an effective waterproof barrier to prevent moisture from penetrating into the connection, thereby protecting the integrity of the water supply and drainage system. At the same time, wrapping with the waterproof cloth can reduce the risk of the connection between the first pipe and the second pipe being eroded by moisture and extend the service life of the first pipe and the annular airbag.

[0009] Preferably, a plurality of elastic ropes are provided in the middle of the side wall of the waterproof cloth; the elastic ropes are arranged corresponding to the cavities; a limiting block is slidably matched in the middle of the side wall of the elastic rope; by setting the elastic ropes and the limiting blocks in this step, the waterproof cloth can be tightly attached to the surface of the second pipe, and the first airbag can be tightly attached to the surface of the first pipe, reducing the existence of gaps and voids, improving the sealing performance. At the same time, this setting can maintain the stability and sealing of the waterproof cloth and the first airbag even under the condition of large water pressure or water flow impact, preventing water penetration.

[0010] Preferably, a cover plate is fixedly connected to the middle of the side wall of the fixed plate; the cover plate covers the connection part of the first pipe and the second pipe; by setting the cover plate in this step, it can effectively prevent moisture, gas or other media from penetrating into the water supply and drainage system through the gaps at the connection part, ensuring the sealing and waterproofness of the water supply and drainage system, and the cover plate can protect the connection part of the first pipe and the second pipe from the direct influence of the external environment, reducing corrosion and wear at the connection part.

[0011] Preferably, a branch air pipe is fixedly connected to the middle of the side wall of the air delivery pipe; the branch air pipe and the air delivery pipe are hollow and communicated; there is an air storage cavity between the cover plate and the annular airbag; by setting the branch air pipe and the air storage cavity in this step, the pressure difference inside and outside the pipe can be increased, reducing the situation of water backflow.

[0012] Preferably, a sealing gasket is fixedly connected to the outer wall of the annular airbag; the sealing gasket is made of anti-slip material; by setting the sealing gasket on the outer wall of the annular airbag in this step, the friction between the outer wall of the annular airbag and the inner wall of the second pipe can be increased, so that the annular airbag can fit more tightly on the inner wall of the second pipe after inflation, further reducing the possibility of air leakage or water seepage.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. For a quick connection joint for a water supply pipe described in the present utility model, by setting the annular airbag and the air delivery pipe, the temporary connection of the first pipe and the second pipe can be quickly completed. When the second pipe is accidentally broken, damaged or in need of emergency repair, in order to maintain the continuity of water supply or prevent waste of water resources, the annular airbag can be used to temporarily connect the first pipe and the second pipe to form a temporary closed system for component replacement work. By setting the first airbag and the cavity, the uneven structure can be used to better fit the uneven parts of the inner wall of the second pipe, forming a tighter fit, thereby reducing the risk of leakage. At the same time, the uneven design can play a role in physical locking, preventing the connection part of the first pipe and the second pipe from loosening or displacing due to external forces. By setting the second airbag, the water flow can be quickly guided into the second pipe, reducing the residence time of the water flow on the inner wall of the second pipe, thereby keeping the second pipe unobstructed.

[0015] 2. For the quick-connection joint for a water supply pipe described in the present utility model, by providing an annular notch and an annular hard plate, the deformation of the end of the first pipe when being squeezed by the annular airbag, the first airbag and the second airbag can be reduced, thereby preventing the second pipe from being completely blocked from the inside, which may cause the first pipe to be unable to supply water to the inside of the second pipe.

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Specific embodiments are given below.

[0025] As Figures 1 to 4As shown in the figure, a quick connection joint for a water supply pipeline according to an embodiment of the present utility model includes a first pipeline 1; a second pipeline 11 is provided in the middle of the side wall of the first pipeline 1; the second pipeline 11 is sleeved outside the first pipeline 1; a ring-shaped airbag 12 is fixedly connected to the middle of the side wall of the first pipeline 1; an air delivery pipe 13 is fixedly connected to the middle of the side wall of the ring-shaped airbag 12; the ring-shaped airbag 12 and the air delivery pipe 13 are hollow and communicated; a first airbag 14 is fixedly connected to the middle of the side wall of the ring-shaped airbag 12; the first airbag 14 is hollow and communicated with the ring-shaped airbag 12; a plurality of cavities 15 are provided between the second pipeline 11 and the first airbag 14; a second airbag 16 is fixedly connected to the middle of the side wall of the first airbag 14; the second airbag 16 is arranged in a funnel-shaped structure; the second airbag 16 is hollow and communicated with the first airbag 14; during operation, maintenance personnel insert the end of the first pipeline 1 into the inside of the second pipeline 11. Since the ring-shaped airbag 12 and the air delivery pipe 13 are hollow and communicated, when the air delivery pipe 13 is connected to a blower, air flow will flow into the inside of the ring-shaped airbag 12 through the air delivery pipe 13, causing the ring-shaped airbag 12 to expand and seal the connection between the first pipeline 1 and the second pipeline 11. Also, because the first airbag 14 is communicated with the ring-shaped airbag 12, when air flow enters the inside of the ring-shaped airbag 12, the air flow also surges into the inside of the first airbag 14, causing the first airbag 14 to expand and press against the second pipeline 11 from the inside. Also, because the second airbag 16 is communicated with the first airbag 14, when air flow enters the inside of the first airbag 14, the air flow simultaneously enters the inside of the second airbag 16, causing the second airbag 16 to expand. Since the second airbag 16 is arranged in a funnel-shaped structure, the second airbag 16 can guide the water flow inside the first pipeline 1 into the inside of the second pipeline 11. This step can quickly complete the temporary connection between the first pipeline 1 and the second pipeline 11 by setting the ring-shaped airbag 12 and the air delivery pipe 13. When the second pipeline 11 is accidentally broken, damaged or needs emergency repair, in order to maintain the continuity of water supply or prevent waste of water resources, the ring-shaped airbag 12 can be used to temporarily connect the first pipeline 1 and the second pipeline 11 to form a temporary closed system for component replacement work. By setting the first airbag 14 and the cavities 15, their uneven structure can be used to better fit with the uneven parts of the inner wall of the second pipeline 11 to form a closer fit, thereby reducing the risk of leakage. At the same time, the uneven design can play a role of physical locking to prevent the connection between the first pipeline 1 and the second pipeline 11 from loosening or displacing due to external force. By setting the second airbag 16, the water flow can be quickly guided into the inside of the second pipeline 11, reducing the residence time of the water flow on the inner wall of the second pipeline 11, thereby keeping the second pipeline 11 unobstructed.

[0026] As Figures 2 to 4As shown, a circular notch 2 is provided in the middle of the side wall of the first pipe 1; a circular hard board 21 is fixedly connected to the inner side wall of the circular notch 2; the circular hard board 21 is made of a rigid material; during operation, after the maintenance personnel insert the end of the first pipe 1 into the second pipe 11 and let water flow into the second pipe 11, the annular airbag 12, the first airbag 14 and the second airbag 16 will start to expand under the action of the blower and squeeze the end of the first pipe 1. At this time, the circular hard board 21 arranged inside the circular notch 2 will support the end of the first pipe 1 from inside the first pipe 1. By setting the circular notch 2 and the circular hard board 21 in this step, the deformation of the end of the first pipe 1 when being squeezed by the annular airbag 12, the first airbag 14 and the second airbag 16 can be reduced, so as to prevent the second pipe 11 from being completely blocked from the inside, resulting in the situation that the first pipe 1 cannot let water flow into the second pipe 11.

[0027] As Figure 1 , Figure 2 and Figure 4 shown, a fixing plate 3 is fixedly connected to the middle of the side wall of the first pipe 1; a waterproof cloth 31 is fixedly connected to the middle of the side wall of the fixing plate 3; the waterproof cloth 31 covers the connection between the first pipe 1 and the second pipe 11; the waterproof cloth 31 is made of an elastic material; during operation, after the first pipe 1 and the second pipe 11 establish a temporary connection, the maintenance personnel pull the waterproof cloth 31 on the side wall of the first pipe 1 and pull the waterproof cloth 31 to the side wall of the second pipe 11, so that the waterproof cloth 31 wraps the second pipe 11 and covers the connection between the first pipe 1 and the second pipe 11. By setting the waterproof cloth 31 with excellent waterproof performance in this step, it can be closely attached to the connection between the first pipe 1 and the second pipe 11, forming an effective waterproof barrier to prevent water from penetrating into the connection, thereby protecting the integrity of the water supply and drainage system. At the same time, using the waterproof cloth 31 for wrapping can reduce the risk of the connection between the first pipe 1 and the second pipe 11 being eroded by water and extend the service life of the first pipe 1 and the annular airbag 12.

[0028] As Figure 1 and Figure 2As shown, multiple elastic cords 4 are provided in the middle of the side wall of the waterproof cloth 31; the elastic cords 4 and the cavity 15 are arranged correspondingly; a limiting block 41 is slidably fitted in the middle of the side wall of the elastic cord 4; during operation, when the waterproof cloth 31 covers the connection between the first pipe 1 and the second pipe 11, maintenance personnel use multiple elastic cords 4 to tighten the waterproof cloth 31 from the outside, and then use the limiting block 41 to fix the elastic cords 4, so that the waterproof cloth 31 tightly adheres to the surface of the second pipe 11. Because the elastic cords 4 and the cavity 15 are arranged correspondingly, multiple elastic cords 4 will also tightly adhere the first airbag 14 to the first pipe 1. This step can make the waterproof cloth 31 tightly adhere to the surface of the second pipe 11 and the first airbag 14 tightly adhere to the surface of the first pipe 1 by setting the elastic cords 4 and the limiting block 41, reducing the existence of gaps and voids, improving the sealing performance. At the same time, this setting can also keep the waterproof cloth 31 and the first airbag 14 stable and airtight even under the condition of large water pressure or water flow impact, preventing water penetration.

[0029] As Figure 2 and Figure 4 shown, a cover plate 5 is fixedly connected to the middle of the side wall of the fixing plate 3; the cover plate 5 covers the connection between the first pipe 1 and the second pipe 11; during operation, after the first pipe 1 and the second pipe 11 establish a temporary connection, maintenance personnel cover the cover plate 5 on the connection between the first pipe 1 and the second pipe 11. This step can effectively prevent moisture, gas or other media from penetrating into the water supply and drainage system through the gaps at the connection by setting the cover plate 5, ensuring the sealing and waterproof performance of the water supply and drainage system, and the cover plate 5 can protect the connection between the first pipe 1 and the second pipe 11 from the direct influence of the external environment, reducing the corrosion and wear at the connection.

[0030] As Figure 2 and Figure 4 shown, a branch air pipe 6 is fixedly connected to the middle of the side wall of the air delivery pipe 13; the branch air pipe 6 and the air delivery pipe 13 are hollow and connected; there is an air storage cavity 61 between the cover plate 5 and the annular airbag 12; during operation, because the branch air pipe 6 and the air delivery pipe 13 are connected, when the cover plate 5 covers the connection between the first pipe 1 and the second pipe 11, when the air delivery pipe 13 blows air into the annular airbag 12, the air flow will flow into the air storage cavity 61 through the branch air pipe 6 and fill the air storage cavity 61 with air flow. This step can increase the pressure difference between the inside and outside of the pipe and reduce the backflow of water by setting the branch air pipe 6 and the air storage cavity 61.

[0031] As Figures 2 to 4As shown, a gasket 7 is fixedly connected to the outer wall of the annular airbag 12; the gasket 7 is made of anti-slip material; by providing the gasket 7 on the outer wall of the annular airbag 12 in this step, the friction between the outer wall of the annular airbag 12 and the inner wall of the second pipe 11 can be increased, so that the annular airbag 12 can fit more tightly on the inner wall of the second pipe 11 after being inflated, further reducing the possibility of air leakage or water seepage.

[0032] Working principle: The maintenance personnel insert the end of the first pipe 1 into the inside of the second pipe 11. Since the annular airbag 12 and the air delivery pipe 13 are hollow and connected, the air delivery pipe 13 is connected to a blower, and the air flow will flow through the air delivery pipe 13 into the inside of the annular airbag 12, causing the annular airbag 12 to expand and seal the connection between the first pipe 1 and the second pipe 11. Also, because the first airbag 14 is connected to the annular airbag 12, when the air flow enters the inside of the annular airbag 12, the air flow also surges into the inside of the first airbag 14, causing the first airbag 14 to expand and press against the second pipe 11 from the inside. Also, because the second airbag 16 is connected to the first airbag 14, when the air flow enters the inside of the first airbag 14, the air flow simultaneously enters the inside of the second airbag 16, causing the second airbag 16 to expand. Since the second airbag 16 is of a funnel-shaped structure, the second airbag 16 can guide the water flow inside the first pipe 1 into the inside of the second pipe 11. After the maintenance personnel insert the end of the first pipe 1 into the inside of the second pipe 11 and let water flow into the inside of the second pipe 11, the annular airbag 12, the first airbag 14, and the second airbag 16 will start to expand under the action of the blower and press against the end of the first pipe 1. At this time, the annular hard board 21 arranged inside the annular notch 2 will support the end of the first pipe 1 from inside the first pipe 1. After the first pipe 1 and the second pipe 11 establish a temporary connection, the maintenance personnel pull the waterproof cloth 31 on the side wall of the first pipe 1 and pull the waterproof cloth 31 to the side wall of the second pipe 11, so that the waterproof cloth 31 wraps around the second pipe 11 and covers the connection between the first pipe 1 and the second pipe 11. When the waterproof cloth 31 covers the connection between the first pipe 1 and the second pipe 11, the maintenance personnel use multiple elastic ropes 4 to tightly pull the waterproof cloth 31 from the outside, and then use the limit blocks 41 to fix the elastic ropes 4, so that the waterproof cloth 31 closely adheres to the surface of the second pipe 11. Since the elastic ropes 4 and the cavity 15 are correspondingly arranged, the multiple elastic ropes 4 will also tightly adhere the first airbag 14 to the first pipe 1. After the first pipe 1 and the second pipe 11 establish a temporary connection, the maintenance personnel cover the cover plate 5 on the connection between the first pipe 1 and the second pipe 11. Since the branch air pipe 6 is connected to the air delivery pipe 13, when the cover plate 5 covers the connection between the first pipe 1 and the second pipe 11, when the air delivery pipe 13 blows air into the inside of the annular airbag 12, the air flow will flow through the branch air pipe 6 into the inside of the air storage cavity 61 and fill the air storage cavity 61 with air flow. By providing a sealing gasket 7 on the outer wall of the annular airbag 12, the friction between the outer wall of the annular airbag 12 and the inner wall of the second pipe 11 can be increased, so that the annular airbag 12 can more closely adhere to the inner wall of the second pipe 11 after inflation, further reducing the possibility of air leakage or water seepage.
