Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of high-rise drainage tee structures, in particular to a high-rise drainage cyclone tee structure. Background Art
[0002] An important pipe fitting commonly used in the drainage system of high-rise buildings is the high-rise drainage tee. This tee fitting can meet the complex drainage needs of high-rise buildings. It has good pressure resistance and anti-leakage characteristics, and plays a key role in the drainage pipe system of high-rise buildings. The high-rise drainage tee not only has a reasonable structural design, but also is easy and quick to install. It can effectively connect pipes in different directions to ensure smooth drainage, thereby improving the overall operation efficiency of the drainage system of high-rise buildings.
[0003] However, in the drainage network inside high-rise buildings, when large amounts of sewage are injected into vertically arranged risers at a high rate in a short period of time, a dynamic phenomenon will occur, that is, the original air in the pipe is forced to be driven upward, forming an air plug effect. During the movement of this air plug inside the pipe, accompanied by the continuous compression and instantaneous release of air, a series of shock wave energy transfer will be stimulated between the pipe walls. This transient physical process not only directly leads to significant noise pollution, but also poses a risk of mechanical stress shock to the drainage structure and its components. Utility Model Content
[0004] The purpose of the utility model is to provide a cyclone tee structure suitable for high-rise drainage. By providing a cyclone component, the adverse effects of the water hammer effect can be significantly reduced, the generation and propagation of noise can be reduced, and the problem of significant noise pollution caused by large-scale sewage being injected into vertically arranged risers at a high rate in a short period of time can be solved.
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] The utility model is a cyclone tee structure suitable for high-rise drainage, comprising a connecting pipe, on which a drainage mechanism is arranged, and the drainage mechanism comprises a cyclone component, a flow diversion component, a support component and a buffer component;
[0007] The swirl assembly includes a sound insulation layer fixedly connected to the inner wall of the connecting pipe, the inner wall of the sound insulation layer is fixedly connected to a fixing ring, a supporting ring is arranged inside the fixing ring, and a plurality of spiral plates are fixedly connected between the fixing ring and the supporting ring, and the spiral plates are made of corrosion-resistant material.
[0008] Furthermore, the flow splitter assembly includes a plurality of support rods fixedly connected to the top surface of the support ring, and the top ends of the plurality of support rods are fixedly connected with conical flow splitter plates.
[0009] Furthermore, the support assembly comprises a support frame fixedly connected to the inner wall of the support ring, a slide rod slidably penetrates the support frame, and a piston is fixedly connected to the bottom end of the slide rod.
[0010] Furthermore, the buffer assembly is wrapped around a spring which is arranged on the slide rod, the top end of the spring is fixedly connected to the bottom surface of the support frame, and the bottom end of the spring is fixedly connected to the top surface of the piston.
[0011] Furthermore, a shrink tube is fixedly connected to the bottom surface of the support ring, the inner diameter of the shrink tube is the same as the outer diameter of the piston, and the inner wall of the shrink tube is slidably connected to the outer wall of the piston.
[0012] Furthermore, the top end of the connecting pipe is fixedly connected to a first water inlet pipe, a sealing ring is fixedly connected between the connecting pipe and the first water inlet pipe, the outer wall of the connecting pipe is fixedly connected to a second water inlet pipe, the bottom end of the connecting pipe is fixedly connected to a telescopic joint, and the bottom end of the telescopic joint is fixedly connected to a water outlet pipe.
[0013] Furthermore, two diverter ribs are fixedly connected to the inner wall of the connecting pipe, and the two diverter ribs are symmetrically distributed below the first water inlet pipe. The second water inlet pipe is located below the diverter ribs, and the fixing ring is located below the second water inlet pipe.
[0014] The utility model has the following beneficial effects:
[0015] By providing a swirl component, when the water flow is small and flows down from the top of the connecting pipe along the inner wall of the connecting pipe or falls through the inside of the connecting pipe, the water flow will pass through the conical diverter plate to the spiral plate, and the water flow will swirl down along the spiral plate, thereby slowing down the flow rate of the water flow, so that the water flow will pass through the spiral plate in the form of a swirl and contact the inner wall of the connecting pipe, so that the adverse effects of the water hammer effect when the water flow passes through the sound insulation layer are significantly reduced, thereby reducing the generation and propagation of noise.
[0016] 2. By providing a buffer component, when the first water inlet pipe and the second water inlet pipe are both connected to water flow and the water flow is large, the inside of the connecting pipe is filled with water flow. At this time, the water flow will flow into the inside of the shrink tube through the gap between the support rod and the conical diverter plate. At this time, the water pressure above the fixed ring is large, and the piston and the slide rod are driven to move downward synchronously while punching the piston. At this time, the spring is stretched. When the water pressure is too large, the piston moves to the bottom of the shrink tube, allowing the water flow to flow out from the gap between the piston and the shrink tube. This not only effectively absorbs and attenuates the vibration energy generated by water hammer, but also alleviates the turbulence effect caused by excessive water flow, further reducing the noise generated by the water flow.
[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The flow splitter assembly includes a plurality of support rods 25 fixedly connected to the top surface of the support ring 23, and a conical flow splitter plate 26 is fixedly connected to the top of the plurality of support rods 25.

By providing a drainage mechanism 2, when the water flow is small and flows down along the inner wall of the connecting pipe 1 from above or falls through the inside of the connecting pipe 1, the water flow will pass through the conical diverter plate 2 6 causes the water flow to swirl down along the spiral plate 24, thereby slowing down the flow rate of the water flow, so that the water flow passes through the spiral plate 24 in a swirling form and contacts the inner wall of the connecting pipe 1, so that the water flow significantly reduces the adverse effects of the water hammer effect when passing through the sound insulation layer 21, and reduces the generation and propagation of noise. When the first water inlet pipe 11 and the second water inlet pipe 12 are both connected to the water flow and the water flow is large, the interior of the connecting pipe 1 is filled with water flow, and at this time the water flow passes through the support rod 25 and the conical diverter plate 26. The water flows into the interior of the contraction tube 292 through the gap between the piston 29 and the contraction tube 292. At this time, the water pressure above the fixing ring 22 is relatively large, and the piston 29 and the slide rod 28 are driven to move downward synchronously while punching the piston 29. At this time, the spring 291 is stretched. When the water pressure is too large, the piston 29 moves to the bottom of the contraction tube 292, so that the water flow can flow out from the gap between the piston 29 and the contraction tube 292, which not only effectively absorbs and attenuates the vibration energy generated by water hammer, but also can alleviate the turbulence effect caused by excessive water flow, and further reduce the noise generated by the water flow.

The two diverter ribs 4 can disperse the water flow in advance so that the water flow can be guided to the inner wall of the connecting pipe 1 when it is weak. The second water inlet pipe 12 is combined with the connecting pipe 1 in an eccentric connection manner. The inner wall of the standpipe of the connecting pipe 1 flows in an orderly manner, thereby avoiding direct collision with the mainstream water flow in the connecting pipe 1, effectively preventing the occurrence of water hammer effect, and improving the stability and durability of the entire drainage system.
[0030] A specific application of this embodiment is: by providing a drainage mechanism 2, when the water flow is small and flows downstream from the top of the connecting pipe 1 along the inner wall of the connecting pipe 1 or falls through the inside of the connecting pipe 1, the water flow will pass through the conical diverter plate 26 to the spiral plate 24, and the water flow will swirl down along the spiral plate 24, thereby slowing down the flow rate of the water flow, so that the water flow will pass through the spiral plate 24 in the form of a swirl and contact the inner wall of the connecting pipe 1, so that when the water flow passes through the sound insulation layer 21, the adverse effects of the water hammer effect are significantly reduced, and the generation and propagation of noise are reduced. When the first water inlet pipe 11 and the second water inlet pipe 12 are both connected to the water flow and when the water flow is large, the inside of the connecting pipe 1 is filled with water flow. At this time, the water flow will flow into the inside of the contraction tube 292 through the gap between the support rod 25 and the conical diverter plate 26. At this time, the water pressure above the fixing ring 22 is large, and the piston 29 and the sliding rod 28 are driven to move downward synchronously while punching the piston 29. At this time, the spring 291 is stretched. When the water pressure When the pressure is too large, the piston 29 moves to the bottom of the contraction tube 292, so that the water flow can flow out from the gap between the piston 29 and the contraction tube 292, which not only effectively absorbs and attenuates the vibration energy generated by water hammer, but also alleviates the turbulence effect caused by excessive water flow, and further reduces the noise generated by the water flow. The sealing ring 14 and the expansion joint 3 cooperate with each other, which not only increases the sealing of the overall device, but also enables the second water inlet pipe 12 and the expansion joint 3 to be disassembled for easy internal maintenance. When the water flow flows into the interior of the connecting pipe 1 through the first water inlet pipe 11, the two diversion ribs 4 can disperse the water flow in advance, so that the water flow can be diverted to the inner wall of the connecting pipe 1 when it is weak. The second water inlet pipe 12 is combined with the connecting pipe 1 in an eccentric connection manner. The inner wall of the standpipe of this single connecting pipe 1 flows in an orderly manner, thereby avoiding direct collision with the mainstream water flow in the connecting pipe 1, effectively preventing the occurrence of the water hammer effect, and improving the stability and durability of the entire drainage system.
