Description

Technical Field

[0001] This utility model relates to the field of maintenance technology for large-flow water supply networks, and in particular to a large-flow leak-stopping device for outdoor water supply networks. Background Technology

[0002] During the operation of the water supply network, leaks often occur due to defects in the quality of the network construction process, exceeding the service life, and large temperature differences between day and night in winter. In severe cases, the entire network will shut down, causing inconvenience to residents or water users and resulting in significant economic losses.

[0003] For small-flow water supply networks, leaks can be successfully plugged even when the network is in normal operation and does not affect production and daily life in the city and surrounding areas. However, for large-flow water supply networks, due to the high internal water pressure, leak plugging requires shutting off the water supply and removing a large amount of water that has been retained in the network, resulting in a waste of water resources. Utility Model Content

[0004] The purpose of this utility model is to provide a high-flow-rate, non-stop water supply leak sealing device for outdoor water supply networks. It can seal leaks in high-flow-rate water supply pipes without interrupting water supply, thereby avoiding impact on production and daily life in cities and surrounding areas and reducing water waste.

[0005] To achieve the above objectives, a high-flow-rate, uninterrupted water supply leak-sealing device for outdoor water supply networks is provided. The device includes a water supply pipe body. The surface of the water supply pipe body has two opposing semi-cylindrical retainers, forming a complete cylinder. The water supply pipe body is located between the two retainers and passes through the middle of both retainers. A hinge is installed at one end of each retainer, and the two retainers are rotatably connected via the hinge. Sealing gaskets are fixedly connected to the opposite ends of each retainer, and the sealing gaskets are respectively located at both ends of the retainers. The gasket is located between the main body of the water supply pipe and the clamping shell. Steel wires are provided on both sides of the gasket, and these wires are welded to the clamping shell in a wavy shape. Connecting ropes are threaded through these steel wires, with one end of each rope passing through the gap between the steel wires on both sides of the gasket and the clamping shell. One end of the connecting rope between the two steel wires passes through the middle of the gasket. A fixing plate is fixedly connected to the end of the clamping shell away from the hinge. The fixing plate has screw holes on its surface, and fixing bolts are installed in these holes. The two clamping shells are connected to each other through the fixing bolts and the fixing plate. This system can seal leaks in high-flow-rate water supply pipes without interrupting the water supply, preventing disruption to production and daily life in the city and surrounding areas, and reducing water waste.

[0006] According to the aforementioned high-flow-rate, uninterrupted water supply leak-sealing device for outdoor water supply networks, drain valves are installed on opposite sides of the two clamps, with the inner diameter of the middle part of each clamp being larger than the diameter of the main body of the water supply pipe. During the leak-sealing process, if the water pressure in the device is too high, the drain valves discharge water from the device to prevent excessive water pressure from affecting the leak sealing of the water supply pipe. Furthermore, when the water pressure in the device is low, the drain valves seal off any leaks in the water supply pipe, reducing water waste.

[0007] According to the aforementioned outdoor water supply network high-flow-rate uninterrupted water supply leak sealing device, the connecting rope is made of high-strength nylon rope. Using high-strength nylon rope as the connecting rope gives it both high strength and flexibility.

[0008] According to the aforementioned high-flow-rate uninterrupted water supply leak-sealing device for outdoor water supply networks, rubber gaskets are fixedly connected to the opposite ends of the two clamping shells. The rubber gaskets are used to reduce the gap between the two clamping shells and ensure the sealing of the water supply pipe by both clamping shells.

[0009] According to the aforementioned high-flow-rate, non-stop leak-proof device for outdoor water supply networks, the diameter of the drain valve is 1 / 5 to 1 / 3 of the diameter of the cylinder composed of two clamping shells. This ensures that the drain valve can regulate the water pressure within the device while preventing the device from becoming too heavy.

[0010] According to the aforementioned outdoor water supply network high-flow-rate uninterrupted water supply leak sealing device, the drain valve has a sealing cap at the end away from the clamp, and the drain valve extends into the sealing cap and is threadedly connected to the sealing cap. The sealing cap is used to close the drain valve after the device has sealed the water supply pipe, preventing water in the water supply pipe from leaking through the drain valve when water is subsequently supplied to the water supply pipe and the internal water pressure is too high.

[0011] The above solution has the following advantages: by welding steel wire to both sides of the sealing gasket at the metal connection between the device and the water supply pipe, and by using a connecting rope to thread through the steel wire and pass through the sealing gasket, the sealing gasket is fixed by the cooperation of the connecting rope and the steel wire, thus preventing the sealing gasket from falling off due to the impact of high-pressure water.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] Reference Figure 1-5This utility model discloses a high-flow-rate, non-stop leak-stopping device for outdoor water supply networks. It includes a water supply pipe body 5. The surface of the water supply pipe body 5 has two opposing semi-cylindrical retainers 2, forming a complete cylinder. Drain valves 4 are installed on opposite sides of the two retainers 2. The inner diameter of the retainer 2 is larger than the diameter of the water supply pipe body 5. During the leak-stopping process, if the water pressure in the device is too high, the drain valves 4 discharge water from the device to prevent excessive water pressure from affecting the leak-stopping of the water supply pipe. Conversely, when the water pressure in the device is low, the drain valves 4 seal off any leaks in the water supply pipe, reducing water leakage. To minimize water waste, the diameter of the drain valve 4 is 1 / 5 to 1 / 3 of the diameter of the cylinder formed by the two retaining shells 2. This allows the drain valve 4 to regulate the water pressure in the device while preventing the device from becoming too heavy. The main body 5 of the water supply pipe is located between the two retaining shells 2 and passes through the middle of the two retaining shells 2. A hinge 3 is installed at one end of each retaining shell 2, and the two retaining shells 2 are rotatably connected by the hinge 3. Sealing gaskets 9 are fixedly connected to the opposite ends of the two retaining shells 2, and the sealing gaskets 9 are respectively located at both ends of the retaining shell 2. The sealing gaskets 9 are located between the main body 5 of the water supply pipe and the retaining shells 2, and the two sides of the sealing gaskets 9 are respectively A steel wire 12 is provided, and the steel wire 12 is welded to the clamping housing 2 in a wavy shape. A connecting rope 11 is inserted through the steel wire 12, and one end of the connecting rope 11 passes through the gap between the steel wire 12 and the clamping housing 2 on both sides of the sealing gasket 9. The connecting rope 11 is made of high-strength nylon rope. The use of high-strength nylon rope as the connecting rope 11 gives the connecting rope 11 high strength and flexibility. One end of the connecting rope 11 between the two steel wires 12 passes through the middle of the sealing gasket 9. A fixing plate 7 is fixedly connected to the end of the clamping housing 2 away from the hinge 3. The surface of the fixing plate 7 has screw holes 10, and a fixing plate 7 is provided in the screw holes 10. Bolt 6, and the two clamping shells 2 are connected to each other by fixing bolt 6 and fixing plate 7. Rubber pads 8 are fixedly connected to the opposite ends of the two clamping shells 2 respectively. The rubber pads 8 are used to reduce the gap between the two clamping shells 2 and ensure the sealing of the two clamping shells 2 to the water supply pipe. The drain valve 4 is provided with a sealing cover 1 at the end away from the clamping shell 2, and the drain valve 4 extends into the sealing cover 1 and is threadedly connected to the sealing cover 1. The sealing cover 1 is used to close the drain valve 4 after the device has sealed the water supply pipe, so as to prevent water in the water supply pipe from leaking through the drain valve 4 when water is subsequently supplied to the water supply pipe and the internal water pressure is too high.

[0023] Working principle: When in use, remove the sealing cap 1 on the drain valve 4, open the cylinder composed of the two clamps 2 through the hinge 3, put the two clamps 2 on the water supply pipe body 5, and make the leak in the water supply pipe body 5 located in the two clamps 2. Use the fixing bolt 6 to pass through the fixing plate 7 on the two clamps 2 to make the two clamps 2 tightly connected. During the process, the water leaking from the water supply pipe body 5 enters the cylinder composed of the two clamps 2. When the water pressure in the clamps 2 is too high, the water in the device is discharged through the drain valve 4 to avoid the water pressure affecting the connection of the two clamps 2. After the leak is plugged, screw the sealing cap 1 on the drain valve 4 to seal the drain valve 4.
