Abstract
Description
Technical Field
[0001] The utility model relates to the field of floor heating pipelines, in particular to a combined pipeline connected with multiple pipe openings. Background Art
[0002] In the floor heating system, it is necessary to arrange several pipes so that water can flow in the pipes to realize the transportation of hot and cold water. In order to make the water flow smoothly in the pipes and shorten the flow path, multi-pipe pipes are usually used to save bends. Generally speaking, when arranging floor heating pipes, there are several parallel horizontally arranged pipes and several parallel vertically arranged pipes. At the intersection of the horizontally arranged pipes and the vertically arranged pipes, there are two different connection methods, and different connectors are required to connect the pipes. It is common to use hot melt to connect the connector at the 90° turn between a horizontally arranged pipe and a vertically arranged pipe. When a horizontally arranged pipe and two vertically arranged pipes intersect to form three phases, a three-way joint is generally used to connect the three. Similarly, a vertically arranged pipe and two horizontally arranged pipes intersect to form three phases. A three-way joint is also used to connect. The existing pipe intersections are prone to water leakage due to unstable connections. In severe cases, the wooden floor may even be soaked and rotten, causing instability to users.

[0023] The following is combined with Figure 1-5 The embodiments of the present utility model are described in detail.
[0024] Example 1
[0025] The utility model relates to a combined pipeline connected with multiple pipe openings, comprising a plurality of pipes 1 which are arranged horizontally and parallel to each other and a plurality of pipes 1 which are arranged vertically and parallel to each other, wherein a protrusion 2 and a groove 3 are arranged at the end of the pipe 1; wherein the protrusion 2 can be adapted to a connector of a first caliber, and the groove 3 can be adapted to a connector of a second caliber, and the first caliber is not equal to the second caliber; a positioning groove 11 is provided at the end of the pipe 1, and a threaded hole 201 is provided in the positioning groove 11, wherein the threaded hole 201 is deepened from the bottom of the positioning groove 11 along the radial direction of the pipe 1 and penetrates the side wall of the groove 3 close to the positioning groove 11; a connecting rod 301 is penetrated in the threaded hole 201, and an external thread matching the threaded hole is provided on the connecting rod, and one end of the connecting rod 301 is fixed in the positioning groove 11 by a nut, and the other end of the connecting rod 301 is located in the groove 3 and connected to a fixing member 302 in the groove 3, and the connecting rod 301 and the fixing member 302 are used to fix the connector of the second caliber in the groove 3.
[0026] Specifically, this embodiment introduces in detail a combined pipeline with multiple pipe openings, which is composed of a plurality of pipes 1 arranged horizontally and parallel to each other and a plurality of pipes 1 arranged vertically and parallel to each other. This combined pipeline achieves flexible adaptation of connectors of different calibers by setting protrusions 2 and grooves 3, thereby improving the flexibility and adaptability of pipeline layout. In order to facilitate structural stability, the protrusions 2 and the pipes 1 are preferably integrally formed. The combined pipeline includes horizontal and vertical pipes 1, which are arranged in parallel to form a grid-like structure. Taking the pipes 1 in the floor heating system as an example, these pipes 1 can be made of corrosion-resistant, high-strength materials, such as stainless steel or polymer plastics, to ensure stability and reliability during long-term use.
[0027] For the first caliber connector, Figure 1-4As shown, the connector matches the protrusion 2 at the end of the pipe 1, and can be tightly connected to the pipe 1 by a clamp, hot melt or other fastening methods. For the connector of the second caliber, in order to make it tightly connected to the pipe 1, a positioning groove 11 is provided at the end of the pipe 1, and a threaded hole 201 is provided in the center of the positioning groove 11 through the protrusion 2 and the side wall of the groove 3 close to the protrusion. A matching connecting rod 301 is provided in the threaded hole 201, one end of the connecting rod 301 is located in the positioning groove 11, and is fixed in the positioning groove 11 by a nut, and the other end of the connecting rod 301 extends into the groove 3 and is connected to the fixing member 302 located in the groove 3. Here, the nut at one end of the connecting rod 301 is fixed in the positioning groove 11, and the connecting rod 301 does not affect the use of the protrusion 2. In order to further enhance the stability of the connector and the groove, there can be two nuts on the connecting rod 301. During operation, the connector is first inserted into the groove 3, and then the connecting rod 301 is screwed toward the groove 3 so that the end of the connecting rod 301 is immersed in the positioning groove 11. At this time, the connecting rod 301 approaches the connector and finally abuts against the connector.
[0028] The advantages of the above design include that each end of the pipe 1 has both a protrusion 2 and a groove 3, which allows for flexible selection of connection methods, and only two types of connectors are required. In other words, there is no need to frequently replace connectors to quickly realize the installation and arrangement of the entire combined pipeline, saving installation time and improving work efficiency.
[0029] Example 2
[0030] This embodiment is an improvement on the embodiment 1, the difference being that the protrusion 2 is extended outward from the end edge of the pipe 1 along the radial direction of the pipe 1, the protrusion 2 surrounds the outside of the pipe 1, and the protrusion 2 is coaxially arranged with the pipe 1.
[0031] Specifically, Figure 3 and 4 As shown, the protrusion 2 extends outward from the end edge of the pipe 1 along the radial direction of the pipe 1, which means that the protrusion 2 expands outward along the diameter direction of the pipe 1. Such a design allows the protrusion 2 to surround the outside of the pipe 1, thereby forming an annular connection surface. Further, the protrusion 2 and the pipe 1 are arranged coaxially, which means that the central axis of the protrusion 2 coincides with the central axis of the pipe 1. This ensures a tight fit between the connector and the pipe 1, and improves the stability and sealing of the connection.
[0032] Example 3
[0033] This embodiment is an improvement made on the basis of the embodiment 2, the difference being that the outer peripheral wall of the protrusion 2 is a smooth surface.
[0034] Specifically, the protrusion 2 in this embodiment is designed for connecting the horizontally arranged pipes 1 and the vertically arranged pipes 1 by hot-melt connection, that is, the connector connects the horizontally arranged pipes 1 and the vertically arranged pipes 1 by hot-melt connection. More specifically, Figure 3 As shown, the outer peripheral wall of the protrusion 2 is designed to be a smooth surface, without protrusions 2, depressions or other irregular shapes, which reduces the friction between the connector and the protrusion 2, making the connection with the pipe 1 smoother. In addition, the smooth surface is also conducive to improving the sealing of the connection and reducing the risk of leakage. Hot melt connection belongs to the prior art, and its connection principle will not be repeated.
[0035] When the outer peripheral wall of the protrusion 2 is a smooth surface, the length of the groove 3 in the axial direction of the pipe 1 is not limited, and the position of the positioning groove 11 is not limited. During operation, the connector is first inserted into the groove 3, and then the connecting rod 301 is screwed in the direction close to the groove 3, so that the end of the connecting rod 301 is immersed in the positioning groove 11. At this time, the connecting rod 301 approaches the connector and finally abuts against the connector.
[0036] It should be noted that, in order to improve the sealing performance of the connection between the connector and the protrusion 2, a sealing ring may be provided in the positioning groove 11, that is, the distance between the positioning groove 11 and the end of the protrusion may be compensated by the sealing ring.
[0037] Example 4
[0038] This embodiment is an improvement made on the basis of the embodiment 2, and the difference is that an external thread 4 is provided on the outer peripheral wall of the protrusion 2.
[0039] Specifically, in addition to the above-mentioned hot melt connection, Figure 4 As shown, the connection method in this embodiment is that the external thread 4 on the outer wall of the pipe 1 and the internal thread of the connector are connected by threads, and the above technical solution can also be implemented.
[0040] When an external thread 4 is provided on the outer peripheral wall of the protrusion 2, the length of the groove 3 in the axial direction of the pipe 1 is greater than the length of the thread on the protrusion 2 along the axial direction of the pipe, and the positioning groove 11 can be provided at a position away from the thread, and its fixing method is the same as that of embodiment 3.
[0041] Example 5
[0042] This embodiment is an improvement made on the basis of Embodiment 4, the difference being that the protrusion 2 includes a cylindrical section 21 and a conical section 22; wherein one end of the cylindrical section 21 is flush with the end of the pipe 1, the other end of the cylindrical section 21 is connected to the conical section 22, and the bottom surface of the conical section 22 is the same as the end surface of the cylindrical section 21.
[0043] Specifically, in order to further improve the sealing of the connection, Figure 3-5 As shown, the protrusion 2 is composed of two parts, a cylindrical section 21 and a conical section 22. One end of the cylindrical section 21 is flush with the end of the pipe 1, ensuring a smooth transition between the protrusion 2 and the pipe 1. The other end of the cylindrical section 21 is connected to the conical section 22, and the bottom surface of the conical section 22 is the same surface as the end surface of the cylindrical section 21, forming a continuous and smooth transition. The conical section 22 is designed to better fit the shape of the connector and provide additional sealing performance. For example, when there is no conical section 22, the connector is only stuck on the cylindrical section 21, and the end of the cylindrical section 21 is at a right angle to the end of the pipe 1, which is not conducive to fixing the connector; the bottom surface of the conical section 22 coincides with the end surface of the cylindrical section 21, and its side surface gradually narrows to the apex, forming a natural guide surface for facilitating the insertion and positioning of the connector.
[0044] Example 6
[0045] This embodiment is an improvement made on the basis of Embodiment 5, and the difference lies in that the external thread 4 is provided in the cylindrical section 21 .
[0046] Specifically, since the connector is “sleeved” on the outside of the protrusion 2 and the cylindrical section 21 is farthest from the center of the pipeline 1 , the external thread 4 is provided on the cylindrical section 21 .
[0047] Example 7
[0048] This embodiment is an improvement on the embodiment 1, the difference being that the groove 3 is deepened from the end edge of the pipe 1 along the axial direction of the pipe 1 toward the other end of the pipe 1, the groove 3 is cylindrical, and the groove 3 is coaxially arranged with the pipe 1.
[0049] Specifically, Figure 3-5 As shown, the groove 3 is provided between the inner wall and the outer wall of the pipe 1 to form a distinction with the protrusion 2, so that the groove 3 is adapted to the connector of the second caliber. More specifically, the starting position of the groove 3 is flush with the end face of the pipe 1, ensuring that it can be seamlessly connected with the connector or other pipes 1 when connected. Take a horizontally arranged pipe 1 connecting two vertically arranged pipes 1 at the same time as an example, that is, one end of a horizontally arranged pipe 1 is simultaneously connected to two vertically arranged pipes 1 one above and one below, and the central axes of the two vertically arranged pipes 1 are located on the same straight line. At this time, a three-way joint is required to connect the three ends, that is, the three joints of the three-way joint are respectively inserted into the grooves 3 at the ends of the three pipes 1. In actual use, the three-way joint and the end can be sealed by a sealing material such as a physical sealing material sealing strip, a sealing ring or a sealing belt, or can be sealed by a chemical sealing material sealant, a sealing paste, etc.
[0050] Example 8
[0051] This embodiment is an improvement made on the basis of the embodiment 7, and the difference lies in that a sealing gasket 5 is provided at the end of the groove 3, and there are at least two sealing gaskets 5, and the two sealing gaskets 5 are stacked.
[0052] Specifically, in order to ensure better sealing after the connector is connected to the groove 3, a sealing gasket 5 is provided at the end of the groove 3. In order to further improve the sealing, there may be multiple sealing gaskets 5 to achieve multiple sealing during connection. In some individual cases, even when the sealing connection of one of the sealing gaskets 5 fails, the sealing effect can be guaranteed.
[0053] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
