[0001] The utility model relates to the technical field of pipeline joints, in particular to a water supply pipeline cut-off joint. Background Art

[0002] Currently, urban municipal water supply networks generally use pipes made of ductile iron, spiral welded steel, and PE. During normal use, water pipes can break or leak for various reasons. Failure to promptly repair these pipes can lead to instability for residents and society. During emergency repairs, it's often necessary to shut off the water flowing through the pipes. However, due to the complexity and age of these pipes, shutting off the water is often impossible. Consequently, repairs can't proceed normally, impacting daily life. Therefore, a device is needed to block water from the pipes and ensure the proper functioning of repairs. Utility Model Content

DETAILED DESCRIPTION

[0034] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0035] To simplify the drawings, only the parts relevant to the utility model are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0036] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0037] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] Reference Figures 1 to 7 , which is the first embodiment of the utility model, proposes a water supply pipe shut-off joint, including: an intercepting pipe section 1 and a water supply pipe 2 are interference fit, and the intercepting pipe section 1 has a plurality of grooves 3; a shut-off valve 4 is arranged at the end of the intercepting pipe section 1 away from the water supply pipe 2, and the shut-off valve 4 is used to open or close the intercepting pipe section 1; there are a plurality of sealing gaskets 5, and the sealing gaskets 5 are arranged in the grooves 3. After the intercepting pipe section 1 is connected to the water supply pipe 2, the side wall of the sealing gasket 5 abuts against the water supply pipe 2.

[0039] In this embodiment, when the water supply pipe 2 cannot be completely closed, the stop valve 4 is first installed on the intercepting pipe section 1, and then the sealing gasket 5 is installed on the intercepting pipe section 1. After the sealing gasket 5 is installed, the stop valve 4 is installed on one end of the intercepting pipe section 1, and then the other end of the intercepting pipe section 1 is installed on the water supply pipe 2. Due to the presence of the sealing gasket 5, it is possible to ensure that the gap between the pipes will not leak, thereby improving the sealing effect. Through the use of the stop valve 4, the water supply pipe 2 can be switched on and off at any time. After the water supply pipe 2 is repaired, the repaired pipe can be directly connected to the stop valve 4 to resume normal use, which reduces the difficulty of restoration and ensures that there is no water interference when the water supply pipe 2 is restored, thereby simplifying the difficulty of the repair operation and improving the speed of restoration.

[0040] As a further technical solution, the intercepting pipe section 1 is interference fit with the inner wall of the water supply pipe 2 , further comprising: a pressure sealing ring 6 is slidably arranged in the intercepting pipe section 1 , and the pressure sealing ring 6 is interference fit with the inner wall of the intercepting pipe section 1 .

[0041] In this embodiment, the pressure sealing ring 6 is arranged inside the intercepting pipe section 1, and the interference fit pipe can ensure that the pressure sealing ring 6 supports the pipe inside the intercepting pipe section 1. When the pressure sealing ring 6 slides to the position where the sealing gasket 5 is located, the pressure sealing ring 6 can press the sealing gasket 5 between the intercepting pipe section 1 and the water supply pipe 2 more tightly, further strengthening the sealing effect of the sealing gasket 5, improving the sealing function of the sealing gasket 5, and reducing the possibility of water leakage.

[0042] As a further technical solution, the pressure sealing ring 6 has a snap-fit ​​groove 7 and also includes: a mounting rod 8 slidingly arranged relative to the intercepting pipe section 1 along the axial direction of the intercepting pipe section 1. After the mounting rod 8 slides, it passes through the stop valve 4 and the intercepting pipe section 1; there are several expansion rods 9, and the several expansion rods 9 are arranged at intervals around the circumference of the mounting rod 8. One end of the expansion rod 9 is set on the mounting rod 8, and the other end is away from the mounting rod 8. After the mounting rod 8 slides, the expansion rod 9 is engaged with the snap-fit ​​groove 7 and drives the pressure sealing ring 6 to slide.

[0043] In this embodiment, when the pressure sealing ring 6 is sealed, the sealing gasket 5 is first installed on the intercepting pipe section 1, and then the stop valve 4 is installed. After the stop valve 4 is installed, the installation rod 8 is passed through the stop valve 4 into the intercepting pipe section 1, and then the pressure sealing ring 6 is matched with the expansion rod 9 to ensure that the pressure sealing ring 6 can be fixed on the expansion rod 9, and then the intercepting pipe section 1 is installed into the water supply pipe 2. Then, by adjusting the position of the installation rod 8, the pressure sealing ring 6 is slid to the specified position to complete the sealing, and it is installed through the expansion rod 9, which ensures the accuracy of the installation position of the pressure sealing ring 6 and improves the efficiency of the installation.

[0044] As a further technical solution, the mounting rod 8 has threads, and further comprises: a hand wheel 10 threadedly connected to the mounting rod 8 , and the hand wheel 10 is located on the side of the stop valve 4 away from the intercepting pipe section 1 .

[0045] In this embodiment, the installation rod 8 is a screw rod and is controlled by a hand wheel 10, which further improves the installation accuracy of the pressure sealing ring 6 while also reducing the difficulty of installation and improving the efficiency of installation.

[0046] As a further technical solution, the invention further comprises: a mounting baffle 11 abuts against a side of the stop valve 4 away from the intercepting pipe section 1 , and a hand wheel 10 is rotatably connected to the mounting baffle 11 .

[0047] In this embodiment, the mounting baffle 11 can assist the rotation of the mounting rod 8, simplifying the installation steps while ensuring that the installation position will not be offset, thereby improving the quality and efficiency of the installation and ensuring the accuracy of the installation.

[0048] As a further technical solution, the expansion rod 9 is made of ferromagnetic material and further includes: a magnet 12 arranged on the mounting rod 8 , and the magnet 12 is used to provide a force for the expansion rod 9 to approach the mounting rod 8 .

[0049] In this embodiment, magnet 12 is fixedly positioned. Once seal ring 6 is installed, mounting rod 8 can be reversed to remove expansion rod 9 from engaging groove 7. At this point, expansion rod 9 is affected by the magnetic force of mounting rod 8, thereby reducing its expansion range and ensuring that expansion rod 9 can be removed from the outlet of stop valve 4. The design of magnet 12 ensures stable recovery of expansion rod 9, thereby improving installation efficiency and saving time for emergency repairs.

[0050] As a further technical solution, it also includes: a mounting block 13 is set at one end of the mounting rod 8, a plurality of mounting grooves 14 are set on the mounting block 13 at intervals, the expansion rod 9 is set on the mounting block 13, and the expansion rod 9 is set in the mounting groove 14 through the mounting block 13.

[0051] In this embodiment, the expansion rod 9 is installed on the mounting block 13 through the mounting groove 14. When installing the pressure sealing ring 6, the operator manually clamps the expansion rod 9 into the clamping groove 7 to ensure the installation of the pressure sealing ring 6. After the installation is completed, the mounting rod 8 is retracted under the action of the magnet 12 to ensure that it can be recovered. The mounting block 13 plays a connecting role to ensure that the movement range of multiple expansion rods 9 is always within the same range.

[0052] As a further technical solution, the pressure sealing ring 6 is a rigid part.

[0053] In this embodiment, the rigid compression sealing ring 6 can provide a stronger supporting force for the intercepting pipe, thereby ensuring the installation strength of the intercepting pipe and preventing leakage.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
