Description

Technical Field

[0001] The utility model relates to the technical field of flow diversion devices, in particular to a flow diversion device used for municipal water supply. Background Art

[0002] The planning of the municipal water supply system is an integral part of the overall urban planning. The municipal water supply system is usually composed of water sources, water pipelines, water plants and distribution networks. After water is taken from the water source, it is sent to the water plant through the water pipeline for water quality treatment. The treated water is pressurized and sent to users through the distribution network. The diversion device plays an important role in the water supply system.

[0003] In the prior art, the publication number (CN215518985U) discloses a diversion device for municipal water supply. When it is necessary to control the flow of water inside a single or individual L-shaped diversion pipe, the gear lever is first pulled accordingly. The gear lever drives the tension plate to squeeze the compression spring, causing the compression spring to deform and shrink. During the contraction of the compression spring, the gear lever follows the movement and leaves the bottom of the guide block. At this time, the installation shaft can be pulled downward, and the installation shaft drives the hexagonal plug rod to move downward. The guide block connected to the hexagonal plug rod slides inside the guide groove, so that the first synchronous pulley can be separated from the contact with the transmission belt. Then, the installation shaft is manually rotated to indirectly drive the threaded rod to rotate, thereby achieving the effect of adjusting the flow size of a single or individual L-shaped diversion pipe. However, the prior art cannot timely release the pressure when the water pressure in the L-shaped diversion pipe is too high, and the high pressure is easy to damage the L-shaped diversion pipe and the equipment in the pipeline.

[0004] Therefore, those skilled in the art have proposed a diversion device for municipal water supply to solve the problems raised in the above background. Utility Model Content

[0005] The purpose of the utility model is to provide a diversion device for municipal water supply to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A diversion device for municipal water supply comprises a mainstream pipe, the mainstream pipe is connected to a plurality of diversion pipes, a diversion port is arranged between the diversion pipe and the mainstream pipe; a movable pipe is movably arranged in the diversion pipe, the movable pipe is fixedly connected to the guide pipe, a flow hole is arranged between the guide pipe and the movable pipe, a limit plate is arranged in the diversion pipe, the limit plate is slidably connected to the guide pipe, a connecting rod distributed in an annular shape is installed on the limit plate, the connecting rod is fixedly connected to the fixed plate, a drain port is opened in the middle of the fixed plate, an elastic component is arranged between the guide pipe and the fixed plate for providing elastic force for the movable pipe, an adjusting component is connected to the guide pipe for adjusting the amount of water flowing through the diversion pipe, a pressure relief port is arranged on the movable pipe, a pressure relief pipe is arranged on the diversion pipe, an outlet pipe is arranged at one end of the diversion pipe away from the mainstream pipe, and a valve is arranged on the outlet pipe.

[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3 A diversion device for municipal water supply, comprising a mainstream pipeline 1, the mainstream pipeline 1 is connected to a plurality of diversion pipelines 2, a diversion port 3 is arranged between the separation pipeline and the mainstream pipeline 1; a movable pipeline 4 is movably arranged in the diversion pipeline 2, the movable pipeline 4 is fixedly connected to the guide pipeline 7, a flow hole 6 is arranged between the guide pipeline 7 and the movable pipeline 4, a limit plate 10 is arranged in the diversion pipeline 2, the limit plate 10 is slidably connected to the guide pipeline 7, and a connecting rod 11 distributed in an annular shape is installed on the limit plate 10 The connecting rod 11 is fixedly connected to the fixed plate 12, and a drain port 13 is opened in the middle of the fixed plate 12. An elastic component is arranged between the diversion pipe 7 and the fixed plate 12 for providing elastic force for the movable pipe 4. The diversion pipe 7 is connected with an adjusting component for adjusting the amount of water flowing through the diversion pipe 2. A pressure relief port 8 is arranged on the movable pipe 4, and a pressure relief pipe 9 is arranged on the diversion pipe 2. An outlet pipe 20 is installed at one end of the diversion pipe 2 away from the mainstream pipe 1, and a valve 21 is arranged on the outlet pipe 20.

[0019] When the diversion pipe 2 assumes the diversion function of the main pipe 1, the valve 21 is opened to allow the water in the main pipe 1 to continuously flow into the diversion pipe 2. The water in the main pipe 1 will flow into the diversion pipe 2 from the diversion port 3. The water flows through the flow hole 6 of the movable pipe 4 into the guide pipe 7, and enters the right end of the diversion pipe 2 through the drain port 13. Then, the water is discharged from the diversion pipe 2 through the outlet pipe 20, thereby realizing the diversion function of the diversion pipe 2. When the water in the diversion pipe 2 flows, an impact force is generated on the regulating component, thereby pushing the regulating component to move to the right, so that the guide pipe 7 connected to the movable pipe 4 will also squeeze the elastic component to the right. When the water pressure is too high and the water flow impact is too large, the regulating component will move to the right. The moving distance becomes longer. When the guide pipe 7 connected to the movable pipe 4 moves to the right to the fixed plate 12, the adjusting component moves to the rightmost end. At this time, the movable pipe 4 also moves to the rightmost end. At this time, the pressure relief port 8 on the movable pipe 4 is connected with the pressure relief pipe 9, so that part of the water in the diversion pipe 2 flows out from the pressure relief pipe 9, thereby achieving the effect of pressure relief. When the adjusting component continues to move to the right under the impact of the high-pressure water flow, the adjusting component will continuously increase the amount of water flow, so that more water can be discharged per unit time, which has the effect of reducing pressure and has a better use effect. The utility model can timely relieve pressure when the water pressure in the diversion pipe 2 is too high, thereby avoiding high pressure damage to the diversion pipe 2 and the equipment in the diversion pipe 2.

[0020] The inner wall of the movable pipe 4 is provided with a pressure sensor 5 for real-time detection of the water pressure in the diversion pipe 2, so as to facilitate the supervisor to make corresponding operations in time.

[0021] The elastic component includes a connecting frame 14 installed on the outer wall of the diversion channel, and a sliding rod 15 distributed in an annular shape and connected to the connecting frame 14 is slidably arranged on the fixed plate 12. A limiting block 16 is installed at one end of the sliding rod 15 away from the connecting frame 14. A spring 17 sleeved on the sliding rod 15 is arranged between the fixed plate 12 and the connecting frame 14. Under the impact of high-pressure water flow, the adjusting component will move to the right, and then the diversion pipe 7 can be driven to move to the right. The connecting frame 14 will drive the sliding rod 15 to move to the right, thereby squeezing the spring 17. When the adjusting component is no longer impacted by the water flow, the adjusting component, the movable pipe 4 and the diversion pipe 7 will be reset under the action of the spring 17.

[0022] The regulating component includes a movable rod 18 connected to the diversion pipe 7, and the movable rod 18 is fixedly connected to the regulating block 19. The regulating block 19 is conical. When water flows in the diversion pipe 2, an impact force will be generated on the regulating block 19, thereby pushing the regulating block 19 to move to the right, so that the diversion pipe 7 connected to the movable pipe 4 will also squeeze the elastic component to the right. When the water pressure is too large and the water flow impact is too large, the distance that the regulating block 19 moves to the right will be longer. When the diversion pipe 7 connected to the movable pipe 4 moves to the right to the fixed plate 12, the regulating block 19 moves to the rightmost end. When the regulating block 19 continues to move to the right under the impact of the high-pressure water flow, the flow channel between the regulating block 19 and the inner wall of the separation pipe will continue to increase, thereby increasing the amount of water flow, so that more water can be discharged per unit time, which plays a role in reducing pressure and has a better use effect.

[0023] When the utility model is in use, water in the mainstream pipe 1 enters the branch pipe 2, and the regulating component will move to the right under the action of the water flow impact, so that the guide pipe 7 connected to the movable pipe 4 will also squeeze the elastic component to the right, and when the water pressure is too high and the water flow impact is too large, the pressure relief port 8 on the movable pipe 4 will be connected with the pressure relief pipe 9, and the pressure relief pipe 9 will be used for auxiliary pressure relief. At the same time, when the regulating component is moved to the right under the impact of the water flow, the regulating component will gradually increase the amount of water passing through, thereby effectively relieving the water pressure, so that the water flow can be smoothly discharged from the water outlet pipe 20 to the branch pipe 2, and the use effect is better. The utility model can timely relieve the pressure when the water pressure in the branch pipe 2 is too high, thereby avoiding high pressure damage to the branch pipe 2 and the equipment in the branch pipe 2.
