Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a pipeline connection casting with a flow-damping plate. Background Technology

[0002] A pipeline is a device for transporting gas, fluid, or fluid containing solid particles, which is made up of pipes, pipe fittings, valves, etc. Pipeline connection castings are used to connect two pipes. Chinese patent document with publication number CN203477671U discloses a pipeline connection casting.

[0003] However, the above technical solutions do not have the function of buffering fluid. Therefore, when in use, if the fluid flow rate between the pipe connection casting and the pipe is too fast, it can easily aggravate the wear of the pipe connection casting and the pipe, and cause problems such as leakage. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of buffering function and excessively high fluid flow rate, by proposing a pipe connection casting with a flow-damping plate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Inlet pipe;

[0008] The buffer plate is welded to the inside of the inlet pipe;

[0009] The buffer box is connected to the left end of the inlet pipe;

[0010] Connecting bucket, the connecting bucket is connected to the opening on the left side of the buffer box;

[0011] Outflow pipe, the outflow pipe is connected to the left end of the connecting bucket;

[0012] The transmission box has two parts, and the transmission box is bolted to the top of the buffer box;

[0013] The water turbine assembly consists of two components, including a blade, a shaft, and a large gear. The blade is bolted to the shaft, and the top of the shaft is keyed to the center of the large gear.

[0014] The buffer mechanism is connected to the large gear. It performs initial buffering of the fluid entering the inlet pipe through the buffer plate, secondary buffering by utilizing the large space inside the buffer box, and third buffering by using the flow to drive the blades to rotate and reduce transmission losses, thereby preventing the flow velocity from being too high.

[0015] In a preferred embodiment of this utility model, the buffer mechanism includes a pinion, a main bevel gear, a secondary bevel gear, and a heat dissipation assembly. Two pinions, two main bevel gears, and two secondary bevel gears are provided. The teeth of the pinion mesh with the teeth of the main gear. The top of the pinion is keyed to the bottom of the main bevel gear. The teeth of the main bevel gear mesh with the teeth of the secondary bevel gear. The secondary bevel gear is keyed to the heat dissipation assembly. The main gear can drive the pinion to rotate, the pinion can drive the main bevel gear to rotate, the main bevel gear can drive the secondary bevel gear to rotate, and the secondary bevel gear can drive the heat dissipation assembly to rotate.

[0016] As a preferred embodiment of this utility model, the heat dissipation assembly includes a rotating rod and a fan impeller. The two ends of the rotating rod are keyed to the shaft centers of two auxiliary bevel gears, and the surface of the rotating rod is keyed to the shaft center of the fan impeller. The auxiliary bevel gears can drive the rotating rod to rotate, and the rotating rod can drive the fan impeller to rotate. After the transmission loss, a better buffering effect is obtained, thereby avoiding excessive flow velocity. Moreover, the rotation of the fan impeller can dissipate heat and prevent the structural transmission from overheating.

[0017] In a preferred embodiment of this utility model, the shaft of the pinion is rotatably connected to the bottom of the transmission box, and the two ends of the rotating rod are rotatably sleeved with the holes of the two transmission boxes respectively. The fan impeller is located between the two transmission boxes. The pinion is rotatably set with the transmission box through bearings to ensure the smooth rotation of the pinion. The rotating rod is rotatably set with the transmission box through bearings to ensure the smooth rotation of the rotating rod. The fan impeller can drive airflow for heat dissipation.

[0018] In a preferred embodiment of this utility model, the top and bottom ends of the rotating shaft are both rotatably connected to the inside of the buffer box, the top end of the rotating shaft extends into the inside of the transmission box, and the rotating shaft is rotatably connected to the buffer box through a bearing to ensure the smoothness of the rotating shaft rotation.

[0019] As a preferred embodiment of this utility model, the right end of the inlet pipe and the left end of the outlet pipe are both integrally machined with flanges, the buffer plates inside the inlet pipe are staggered, and the flanges of the inlet pipe and the outlet pipe can connect pipes and facilitate the connection between pipes.

[0020] Beneficial effects:

[0021] 1. The buffer plate can block and guide the fluid entering the inlet pipe, thereby initially buffering the fluid and reducing its speed.

[0022] 2. The fluid entering the buffer box is buffered again due to the increased space. The fluid then drives the impeller to rotate, which in turn drives the shaft to rotate. The shaft then drives the large gear to rotate, which in turn drives the buffer mechanism to rotate, thus buffering the flow again.

[0023] In this invention: the fluid entering the inlet pipe is initially buffered by the buffer plate, then buffered a second time by the large space inside the buffer box, and finally buffered a third time by the flow driving the blade to rotate and passing through the transmission loss, thereby avoiding excessive flow velocity.

[0039] The buffer mechanism is connected to the large gear 10.

[0040] With the above structure, the fluid entering the inlet pipe 1 is initially buffered by the buffer plate 2, then buffered a second time by the large space inside the buffer box 3, and finally buffered a third time by the flow driving the blade 8 to rotate, after the transmission loss, thereby avoiding excessive flow velocity.

[0041] Please see Figure 2 The buffer mechanism includes a pinion 11, a main bevel gear 12, a secondary bevel gear 13, and a heat dissipation assembly. There are two pinion 11, two main bevel gears 12, and two secondary bevel gears 13. The teeth of the pinion 11 mesh with the teeth of the large gear 10. The top of the pinion 11 is keyed to the bottom of the main bevel gear 12. The teeth of the main bevel gear 12 mesh with the teeth of the secondary bevel gear 13. The secondary bevel gear 13 is keyed to the heat dissipation assembly. The large gear 10 can drive the pinion 11 to rotate. The pinion 11 can drive the main bevel gear 12 to rotate. The main bevel gear 12 can drive the secondary bevel gear 13 to rotate. The secondary bevel gear 13 can drive the heat dissipation assembly to rotate.

[0042] Please see Figure 2 The heat dissipation assembly includes a rotating rod 14 and a fan impeller 15. The two ends of the rotating rod 14 are keyed to the shafts of two secondary bevel gears 13, and the surface of the rotating rod 14 is keyed to the shaft of the fan impeller 15. The secondary bevel gears 13 can drive the rotating rod 14 to rotate, and the rotating rod 14 can drive the fan impeller 15 to rotate. After the transmission loss, a better buffering effect is obtained, thereby avoiding excessive flow velocity. Moreover, the rotation of the fan impeller 15 can dissipate heat and prevent the structural transmission from overheating.

[0043] Please see Figure 4 The pinion 11 is rotatably connected to the bottom of the transmission box 7 at its shaft center. The two ends of the rotating rod 14 are rotatably sleeved with the holes of the two transmission boxes 7 respectively. The fan impeller 15 is located between the two transmission boxes 7.

The buffer plates 2 inside the inlet pipe 1 are staggered. The flanges 6 of the inlet pipe 1 and the outlet pipe 5 can connect the pipes and facilitate the connection between the pipes.

[0046] The working principle of this utility model is as follows: The inlet pipe 1 is fixed to one of the pipes by the flange 6 on the right side, and the flange 6 at the left end of the outlet pipe 5 is connected to another pipe. The buffer plate 2 can block and guide the fluid entering the inlet pipe 1, thereby initially buffering the fluid and reducing its speed. The fluid entering the buffer box 3 is further buffered due to the increased space. The fluid will drive the blade 8 to rotate, which in turn drives the shaft 9 to rotate. The shaft 9 drives the large gear 10 to rotate, which in turn drives the small gear 11 to rotate. The small gear 11 drives the main bevel gear 12 to rotate, which in turn drives the secondary bevel gear 13 to rotate. The secondary bevel gear 13 drives the rotating rod 14 to rotate, which in turn drives the fan impeller 15 to rotate. After the transmission loss, a better buffering effect is achieved, thereby avoiding excessive flow velocity. Moreover, the rotation of the fan impeller 15 can dissipate heat and prevent overheating of the transmission structure.
