A connection structure for municipal pipelines

Abstract

This utility model discloses a connection structure for municipal pipelines. The advantages are as follows: In the connection process between connecting pipe one and connecting pipe two, flange one and flange two are first fitted together, and the limiting pin on connecting assembly one is inserted through flange two into the groove on flange one. Then, by moving the lever on connecting assembly two, the threaded ring moves along connecting pipe one towards the inside of flange one. As the threaded ring moves, it pushes the wedge block away from the center of flange one until the limiting pin is inserted into the limiting hole on the limiting pin. This achieves a reliable limiting connection between flange one and flange two, enabling rapid connection between connecting pipe one and connecting pipe two. Because this connection structure requires only one rotation to connect connecting pipe one and connecting pipe two, it eliminates the tedious process of repeatedly tightening bolts and nuts, thus improving the connection efficiency between connecting pipe one and connecting pipe two.

Description

Technical Field

[0001] This utility model relates to the field of municipal pipeline connection technology, specifically to a connection structure for municipal pipelines. Background Technology

[0002] Municipal water supply facilities are the foundation of urban construction. The main components of water supply facilities include water supply pipelines and water plants. Water plants are used to purify tap water, which is then delivered to users' homes through water supply pipelines. Municipal water supply facilities have become an indispensable infrastructure in modern cities. The construction method for pipelines in related technologies is as follows: a trench is dug at the location to be constructed, each section of pipe is hoisted into the trench, and adjacent sections of pipe are connected.

[0003] Currently, when connecting two adjacent pipelines during municipal construction, the main method is to first align the corresponding flange holes at one end of the two pipelines, and then tighten them with bolts and nuts to achieve the connection between the two adjacent municipal pipelines. Although the bolt and nut locking method can achieve the connection between two adjacent municipal pipelines, the repeated tightening of bolts and nuts during the connection process is cumbersome, resulting in low connection efficiency between two adjacent municipal pipelines. Utility Model Content

[0008] Furthermore, a sealing assembly is installed between the first flange and the second flange, the sealing assembly including a sealing groove and a sealing gasket.

[0009] Furthermore, the sealing gasket is bonded to the flange, the size of the sealing gasket matches the size of the sealing groove, and both the sealing gasket and the sealing groove are annular structures.

[0010] Furthermore, the mounting ring is slidably mounted on the second connecting pipe, the limiting pin passes through the slot on the second flange, and each limiting pin has a limiting hole, with the limiting holes on each limiting pin arranged in a ring relative to the center of the second flange.

[0011] Furthermore, the threaded ring is threaded onto the connecting pipe, and a ring groove is pre-reserved on the flange at the wedge block. Four levers are welded in a ring shape on the outer wall of the threaded ring.

[0012] Furthermore, the portion of the spiral ring that mates with the wedge block has a conical structure, and the limiting post is installed on the side of the wedge block facing away from the spiral ring.

[0013] Furthermore, the spring is installed between the wedge block and the pre-reserved annular groove on the flange, the limiting post passes through the spring, and the size of the limiting post matches the size of the limiting hole.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This invention, by installing a connecting component two on flange one and a connecting component one on flange two, allows for the following connection process: First, flange one and flange two are brought into contact. Then, the limiting pin on connecting component one is inserted through flange two into the slot on flange one. Next, by moving the lever on connecting component two, the threaded ring moves along connecting pipe one towards the inside of flange one. As the threaded ring moves, it pushes the wedge block away from the center of flange one until the limiting pin is inserted into the limiting hole on the limiting pin. This achieves a reliable limiting connection between flange one and flange two, enabling rapid connection between connecting pipe one and connecting pipe two. Because this connection structure requires only one rotation to connect connecting pipe one and connecting pipe two, it eliminates the tedious process of repeatedly tightening bolts and nuts, thus improving the connection efficiency between connecting pipe one and connecting pipe two.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figures 1-3 As shown in this embodiment, a connection structure for municipal pipelines includes a connecting pipe 2, a connecting pipe 5 on one side of the connecting pipe 2, a flange 3 installed on the end of the connecting pipe 2 facing the connecting pipe 2 5, a connecting assembly 6 installed on the flange 3, the connecting assembly 6 including a limiting post 601, a spring 602, a lever 603, a threaded ring 604, and a wedge block 605, a flange 4 installed on the end of the connecting pipe 2 5 facing the connecting pipe 2, a connecting assembly 1 installed on the flange 2 4, the connecting assembly 1 including a limiting hole 101, a limiting pin 102, and a mounting ring 103, which connects the connecting pipe 2 and the connecting pipe 2 5. In the process, flange 3 and flange 4 are first fitted together, and the limiting pin 102 on the connecting assembly 1 is inserted through flange 4 into the slot on flange 3. Then, by moving the lever 603 on the connecting assembly 2, the threaded ring 604 moves along the connecting pipe 2 toward the inside of flange 3. As the threaded ring 604 moves, it pushes the wedge block 605 toward the direction opposite to the center of flange 3 until the limiting pin 601 is inserted into the limiting hole 101 on the limiting pin 102. This achieves a reliable limiting connection between flange 3 and flange 4, thereby realizing a quick connection between connecting pipe 2 and connecting pipe 2.

[0024] like Figures 1-3As shown, in this embodiment, a sealing assembly 7 is also installed between flange 3 and flange 4. The sealing assembly 7 includes a sealing groove 702 and a sealing gasket 701. The sealing gasket 701 is bonded to flange 3. The size of the sealing gasket 701 matches the size of the sealing groove 702. Both the sealing gasket 701 and the sealing groove 702 are annular structures. When flange 3 and flange 4 are fitted together, the sealing gasket 701 will be inserted into the sealing groove 702 to achieve a reliable seal between flange 3 and flange 4, thereby ensuring a reliable seal between connecting pipe 2 and connecting pipe 5 after installation.

[0025] like Figures 1-3 As shown, in this embodiment, the mounting ring 103 is slidably mounted on the connecting pipe 2 5, and the limiting pin 102 passes through the slot on the flange 2 4. Each limiting pin 102 has a limiting hole 101. The limiting holes 101 on each limiting pin 102 are arranged in a ring relative to the center of the flange 2 4, so that the limiting holes 101 are arranged in a ring around the center of the flange 2 4. After the limiting pin 102 is inserted into the slot on the flange 1 3, it can be ensured that the limiting hole 101 can be aligned with the limiting post 601. The threaded ring 604 is installed on the connecting pipe 1 2 by threads. The flange 1 3 has a reserved ring groove at the wedge block 605. Four levers 603 are welded in a ring on the outer wall of the threaded ring 604. The levers 603 can be used to realize the convenient rotation adjustment of the threaded ring 604.

[0026] like Figures 1-3 As shown, in this embodiment, the part of the screw ring 604 that mates with the wedge block 605 has a conical structure. The limiting post 601 is installed on the side of the wedge block 605 facing away from the screw ring 604. The design of the conical structure on the screw ring 604 can ensure that the screw ring 604 can easily push the wedge block 605 when it is screwed into the connecting pipe 2, so that the wedge block 605 can push the limiting post 601 into the limiting hole 101. The spring 602 is installed between the wedge block 605 and the pre-reserved annular groove on the flange 3. The limiting post 601 passes through the spring 602. The size of the limiting post 601 matches the size of the limiting hole 101. The spring 602 is mainly used to realize the automatic reset of the wedge block 605 after the screw ring 604 is removed.

[0027] The specific implementation process of this embodiment is as follows: When connecting the municipal water supply and drainage pipe 2 and the connecting pipe 5, firstly, flange 3 and flange 4 are fitted together, and the limiting pin 102 on the connecting assembly 1 is inserted through flange 4 into the hole groove on flange 3. Then, by moving the lever 603 on the connecting assembly 6, the threaded ring 604 moves along the connecting pipe 2 toward the inside of flange 3. While moving, the threaded ring 604 pushes the wedge block 605 toward the direction opposite to the center of flange 3 until the limiting pin 601 is inserted into the limiting hole 101 on the limiting pin 102. This achieves a reliable limiting connection between flange 3 and flange 4, thereby realizing a quick connection between connecting pipe 2 and connecting pipe 5. Because in this connection structure, the connection between connecting pipe 2 and connecting pipe 5 can be achieved with just one rotation, eliminating the tediousness of repeatedly tightening bolts and nuts, thus improving the connection efficiency between connecting pipe 2 and connecting pipe 5.
