Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of valves, and particularly relates to a rotary reflux valve. Background Technique
[0002] A rotary reflux valve is a valve device that controls the flow direction and flow rate of fluid through a rotating component. When the process device operates at a low load, resulting in a small amount of fluid used by the user at the outlet of the original pump and unable to meet the minimum flow rate requirement of the water pump, it can play an important role. It prevents the reverse flow of fluid through the rotational movement of its own structure and allows the fluid to pass smoothly during normal forward flow. It has the characteristics of good sealing performance, flexible operation, and strong durability, and is widely used in systems such as water supply and drainage, industrial pipelines, heating, ventilation, and air conditioning.
[0003] The amount of fluid used by the user at the outlet of the original pump is small (the process device operates at a low load), unable to meet the minimum flow rate requirement of the water pump. Most of the flow needs to return through the bypass orifice plate to ensure that the water pump does not cavitate. However, this leads to the long-term startup of the bypass, waste of working medium, high pressure, and severe vibration, resulting in excessive pressure fluctuations in the sealing water main pipe. Content of the Utility Model
[0004] The purpose of the utility model is to provide a rotary reflux valve. By setting an expansion mechanism, it solves the problem that the minimum flow rate requirement of the water pump cannot be met, and most of the flow needs to return through the bypass orifice plate to ensure that the water pump does not cavitate. However, this leads to the long-term startup of the bypass, waste of working medium, high pressure, and severe vibration, resulting in excessive pressure fluctuations in the sealing water main pipe.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model is a rotary reflux valve, including a pipeline and an expansion mechanism and a configuration mechanism arranged on the pipeline;
[0007] The expansion mechanism includes a plurality of expansion pipelines fixedly connected to the outer wall of the pipeline. The plurality of expansion pipelines are all communicated with the pipeline. The inner walls of the plurality of expansion pipelines are all fixedly connected with a first rotating shaft. The outer walls of the plurality of first rotating shafts are all rotatably sleeved with rotating blade assemblies. The plurality of rotating blade assemblies are all adapted to the plurality of expansion pipelines.
[0008] Further, the configuration mechanism includes a limiting ring fixedly connected to the outer wall of the pipeline. A first hoop is arranged on the outer wall of the limiting ring. A second hoop is hinged on the first hoop. An installation groove is opened on the first hoop, and a limiting groove is opened on the second hoop.
[0009] Further, a rotating block is rotatably connected to the inner wall of the installation groove. A threaded rod is fixedly connected to the bottom of the rotating block. The threaded rod is adapted to the limiting groove. A limiting block is sleeved on the outer wall of the threaded rod in a threaded manner. The top of the limiting block is in contact with the second hoop.
[0010] Further, a pressure relief pipe is fixedly connected to the outer wall of the pipeline. The pressure relief pipe is communicated with the pipeline. A sealing ring is fixedly connected to the inner wall of the pressure relief pipe. A support rod is fixedly connected to the inner wall of the pressure relief pipe. A sliding rod is slidably connected to the support rod. A piston is fixedly connected to the bottom of the sliding rod. The piston is adapted to the sealing ring.
[0011] Further, a spring is wound around the outer wall of the sliding rod. One end of the spring is fixedly connected to the support rod, and the other end of the spring is fixedly connected to the piston.
[0012] Further, a rotating rod is rotatably connected to the inner wall of the pipeline. The top and bottom ends of the rotating rod both extend outside the pipeline and are both rotatably connected to the pipeline. A blocking block is fixedly sleeved on the outer wall of the rotating rod. The blocking block is adapted to the inner wall of the pipeline.
[0013] Further, a turntable is fixedly connected to the top end of the rotating rod.
[0014] The utility model has the following beneficial effects:
[0015] (1) By setting an expansion mechanism in the utility model, when the pipeline connection is completed, once the water flow in the pipeline reaches the outlet position, since a plurality of expansion pipelines are arranged at the outlet, these expansion pipelines can divert the excess water into their own interiors. In this way, the pressure in the pipeline can be effectively reduced. At the same time, when the water diverted into the expansion pipeline impacts the rotating blade assembly in the expansion pipeline, under the push of this impact force, the rotating blade assembly can start to rotate. The rotation of the rotating blade assembly can slow down the water flow speed, enabling the water flow to slowly flow into the pipeline and then flow out through the outlet. Through this setting, the water flow rate at the outlet can be effectively increased, thereby reducing the influence brought by the water flow pressure of the bypass pipeline.
[0016] (2) By setting a configuration mechanism in the utility model, when the water flow pressure at the outlet of the pipeline is too high, the strong pressure of the water flow will push the piston upward. During the upward movement of the piston, it will cooperate with the sliding rod and the support rod to compress the spring on its outer wall. In this way, the water flow can flow out from the space vacated after the piston moves, thereby achieving the purpose of pressure relief. When the water flow pressure in the pipeline returns to a stable state, the piston will be tightly sealed with the sealing ring on the pressure relief pipe again under the push of the spring to ensure the sealing performance of the pipeline.
[0017] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some, rather than all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.
[0027] Please refer to Figures 1-5As shown in the figure, the utility model relates to a rotary reflux valve, which includes a pipeline 1, an expansion mechanism 2 and a configuration mechanism 3 arranged on the pipeline 1. The expansion mechanism 2 includes a plurality of expansion pipelines 21 fixedly connected to the outer wall of the pipeline 1. The plurality of expansion pipelines 21 are all communicated with the pipeline 1. The inner walls of the plurality of expansion pipelines 21 are all fixedly connected with a first rotating shaft 22. The outer walls of the plurality of first rotating shafts 22 are all rotatably sleeved with a rotating blade assembly 23. The plurality of rotating blade assemblies 23 are all adapted to the plurality of expansion pipelines 21. By setting the expansion mechanism, after the pipeline connection is completed, once the water flow in the pipeline 1 reaches the outlet position, since a plurality of expansion pipelines 21 are arranged at the outlet, these expansion pipelines 21 can divert the excess water into their own interiors. In this way, the pressure in the pipeline 1 can be effectively reduced. At the same time, when the water diverted into the expansion pipeline 21 impacts the rotating blade assembly 23 in the expansion pipeline 21, under the push of this impact force, the rotating blade assembly 23 can start to rotate. The rotation of the rotating blade assembly 23 can slow down the water flow speed, so that the water flow can slowly flow into the pipeline 1 and then flow out through the outlet. Through this setting, the water flow rate at the outlet can be effectively increased, thereby reducing the influence brought by the water flow pressure of the bypass pipeline. The configuration mechanism 3 includes a limiting ring 31 fixedly connected to the outer wall of the pipeline 1. A first hoop 32 is arranged on the outer wall of the limiting ring 31. A second hoop 33 is hinged on the first hoop 32. An installation groove 34 is opened on the first hoop 32. A limiting groove 35 is opened on the second hoop 33. A rotating block 36 is rotatably connected to the inner wall of the installation groove 34. A threaded rod 37 is fixedly connected to the bottom of the rotating block 36. The threaded rod 37 is adapted to the limiting groove 35. A limiting block 38 is threadedly sleeved on the outer wall of the threaded rod 37. The top of the limiting block 38 is in contact with the second hoop 33. A pressure relief pipe 39 is fixedly connected to the outer wall of the pipeline 1. The pressure relief pipe 39 is communicated with the pipeline 1. A sealing ring 391 is fixedly connected to the inner wall of the pressure relief pipe 39. A support rod 392 is fixedly connected to the inner wall of the pressure relief pipe 39. A sliding rod 393 is slidably connected to the support rod 392. A piston 394 is fixedly connected to the bottom of the sliding rod 393. The piston 394 is adapted to the sealing ring 391. A spring 395 is wound around the outer wall of the sliding rod 393. One end of the spring 395 is fixedly connected to the support rod 392, and the other end of the spring 395 is fixedly connected to the piston 394. A rotating rod 396 is rotatably connected to the inner wall of the pipeline 1. The top and bottom ends of the rotating rod 396 both extend outside the pipeline 1 and are both rotatably connected to the pipeline 1. A blocking block 397 is fixedly sleeved on the outer wall of the rotating rod 396. The blocking block 397 is adapted to the inner wall of the pipeline 1. A turntable 398 is fixedly connected to the top end of the rotating rod 396. By setting the configuration mechanism, when the water flow pressure at the outlet of the pipeline 1 is too high, the strong pressure of the water flow will push the piston 394 to move upward. During the upward movement of the piston 394, it will cooperate with the sliding rod 393 and the support rod 392 to compress the spring 395 on its outer wall. In this way, the water flow can flow out from the space vacated after the movement of the piston 394, thereby achieving the purpose of pressure relief.When the water flow pressure in the pipeline 1 returns to stability, the piston 394 will be tightly sealed again with the sealing ring 391 on the pressure relief pipe 39 under the push of the spring 395 to ensure the sealing performance of the pipeline.
[0028] A specific application of this embodiment is as follows: during use, first, the entire pipeline 1 can be docked with the connecting pipeline. Subsequently, the first hoop 32 and the second hoop 33 are sleeved at the interface of the two pipelines. After the sleeving is completed, the threaded rod 37 located on the first hoop 32 is rotated to make it snap into the limiting groove 35 on the second hoop 33. Then, the limiting block 38 on the threaded rod 37 is rotated to cooperate with the second hoop 33 to perform a contraction operation on the first hoop 32 on the threaded rod 37. In this way, the first hoop 32 and the second hoop 33 can quickly connect the entire pipeline 1 with the connecting pipeline. When the pipeline connection is completed, once the water flow in the pipeline 1 reaches the outlet position, since a number of extension pipelines 21 are provided at the outlet, these extension pipelines 21 can divert the excess water into their own interiors. In this way, the pressure in the pipeline 1 can be effectively reduced. At the same time, when the water diverted into the extension pipeline 21 impacts the rotating blade assembly 23 in the extension pipeline 21, under the push of this impact force, the rotating blade assembly 23 can start to rotate. The rotation of the rotating blade assembly 23 can slow down the water flow speed, enabling the water flow to slowly flow into the pipeline 1 and then flow out through the outlet. When the water flow pressure at the outlet of the pipeline 1 is too high, the strong pressure of the water flow will push the piston 394 upward. During the upward movement of the piston 394, it will cooperate with the sliding rod 393 and the support rod 392 to compress the spring 395 on its outer wall. In this way, the water flow can flow out from the space vacated after the movement of the piston 394, thereby achieving the purpose of pressure relief. When the water flow pressure in the pipeline 1 returns to stability, the piston 394 will be tightly sealed again with the sealing ring 391 on the pressure relief pipe 39 under the push of the spring 395 to ensure the sealing performance of the pipeline. When it is necessary to control the water flow in the pipeline 1, it can be achieved by rotating the turntable 398. During the rotation of the turntable 398, the rotating rod 396 and the stopper 397 on the rotating rod 396 will be driven to rotate synchronously. Through such a rotation operation, the opening and closing of the pipeline 1 can be achieved, greatly facilitating the control of the water flow out of the pipeline 1.
