Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline connectors, in particular to a water distribution device for eliminating water hammer. Background Art

[0002] The water flow velocity does not decrease when it enters the water pipe body through the water inlet end. The high-speed water flow enters the water pipe rapidly, which will produce a large water hammer effect and generate greater pressure on the bottom of the water pipe, thereby affecting and endangering the safety of the equipment.

[0003] For example, the publication number "CN201810068632.X" discloses a water hammer reduction valve, a water hammer reduction pipeline, and a method for preventing water hammer in a pipeline, comprising: a valve body provided with a water inlet and a water outlet, a valve core provided in the valve body, the water hammer reduction valve further comprising a single-rod piston cylinder controlled by an external signal, the piston rod of the single-rod piston cylinder being connected to the valve core, the external signal comprising an opening or closing signal of a water pump or valve in the pipeline provided with the water hammer reduction valve, and when a closing signal appears downstream of the incoming water, the single-rod piston cylinder is controlled to press the valve core against the water outlet of the valve body to close the water hammer reduction valve. The present invention can reduce the impact of the backflow water flow on the water hammer reduction valve and even the entire system and can realize the impact energy consumption of the reverse backflow. The present invention effectively reduces the harm of the water hammer effect and ensures the safe operation of the pipeline and its accessories.

[0004] Although the above-mentioned water hammer reduction valve, water hammer reduction pipeline and pipeline water hammer prevention method reduce the water hammer effect, they are mostly used for backflow water. However, when water flows into the pipeline from the pipe inlet, it will still generate impact force on the bottom of the pipe. Summary of the Invention

[0020] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, a brief introduction will be given below to the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0021] Please see Figures 1 to 2A water diversion device for eliminating water hammer includes a water pipe 10 and a water diversion member 20 arranged in the inner cavity of the water pipe 10. The water diversion member 20 is provided with an inclined surface for slowing down the water flow rate and diverting the water flow.

[0022] When water flows into the water pipe 10, it flows into the water pipe 10 in one direction, forming a water hammer effect. The rapid water flow will generate a great impact force on the bottom of the water pipe 10. Therefore, by arranging the water diversion member 20 in the inner cavity of the water pipe 10, the water flow is diverted along the inclined surface by utilizing the inclined surface on the water diversion member 20. At this time, the water flow is dispersed and flows into the water pipe 10. Even if the water flow flows into the water pipe 10 along the inner wall of the water pipe 10, the water flow is prevented from impacting the bottom of the water pipe 10 from one direction, reducing the impact force of the water flow on the bottom of the water pipe 10. In addition, the inclined surface has a decelerating effect on the water flow, which can better divert the water flow and avoid the generation of the water hammer effect.

[0023] Furthermore, the water distribution member 20 includes a primary water distribution member 201 and a secondary water distribution member 202. The primary water distribution member 201 and the secondary water distribution member 202 are arranged in sequence along the direction of water flow, and the primary water distribution member 201 and the secondary water distribution member 202 are rotatably connected. A connecting rod 2011 is provided on the primary water distribution member 201, and the secondary water distribution member 202 is fixedly connected to the inner wall of the water pipe 10 through the connecting rod.

[0024] When water flows into the water pipe 10, the huge water pressure will form a water hammer effect, causing a huge impact force on the bottom of the water pipe 10, which is extremely destructive to the water pipe 10. In order to change this situation, the first-level water distribution member 201 and the second-level water distribution member 202 are set at the water inlet of the water pipe 10. The first-level water distribution member 201 and the second-level water distribution member 202 are concentrically arranged, and the second-level water distribution member 202 and the water pipe 10 are connected by the connecting rod. At the same time, there is a certain distance between the two along the direction of water flow. At the same time, the first-level water distribution member 201 and the second-level water distribution member 202 are concentrically arranged, and the second-level water distribution member 202 and the water pipe 10 are connected. At the same time, there is a certain distance between the two along the direction of water flow. The diameters of the first-level water diversion member 201, the second-level water diversion member 202, and the water pipe 10 increase in sequence. The first-level water diversion member 201 is provided with an inclined surface, which can divert water. When the water flows along the first-level water diversion member 201, the water will form a structure similar to a water curtain. The water forming the water curtain will then be diverted again at the second-level water diversion member 202. The diverted water will then enter the interior of the water pipe 10 along the inner wall of the water pipe 10, preventing the water from directly impacting the bottom of the water pipe 10 and avoiding the occurrence of a water hammer effect.

[0025] In a preferred embodiment, the first-level water distribution member 201 is in the shape of a cone.

[0026] The first-level water distribution member 201 is shaped as a cone, which can better divert water flow. Due to the shape characteristics of the cone itself, the diameter of the lower base of the cone is larger than the diameter of the upper base, that is, the lower base is closer to the inner wall of the water pipe 10, which can better guide the water flow along the inner wall of the water pipe 10, thereby reducing the water hammer effect. At the same time, the impact resistance of the conical first-level water distribution member 201 is better than that of a flat plate, thereby extending the service life of the first-level water distribution member 201.

[0027] In a preferred embodiment, the first-level water distribution component 201 is provided with a rotating through hole 2012 along the axial direction of the cone, and the rotating shaft 2013 is provided inside the rotating through hole 2012. One end of the rotating shaft 2013 is connected to one end of the connecting rod 2011, and the other end of the connecting rod 2011 is connected to the second-level water distribution component 202.

[0028] When the water flow is diverted, in order to reduce the working pressure of the secondary water diversion member 202, the rotating through hole 2012 is opened at the center point of the primary water diversion member 201, and the rotating shaft 2013 is set inside the rotating through hole 2012. The rotating shaft 2013 can rotate the primary water diversion member 201 during operation. When the primary water diversion member 201 rotates, a certain centrifugal force is generated on the water flow. Under the action of the centrifugal force, a part of the water flow flows into the water pipe 10 along the inner wall of the water pipe 10 without passing through the secondary water diversion member 202, thereby reducing the workload of the secondary water diversion member 202 and improving the working efficiency of the primary water diversion member 201.

[0029] Furthermore, an arc-shaped guide groove is provided on the surface of the first-level water distribution member 201 .

[0030] The arc-shaped guide groove 2014 can make the water flow under the action of centrifugal force be better thrown onto the inner wall of the water pipe 10, and the arc-shaped guide groove 2014 forms a regular groove on the surface of the first-level water distribution member 201, which can prevent the water flow from forming water marks on the first-level water distribution member 201, resulting in the need to replace the first-level water distribution member 201 multiple times. In addition, the water distribution effect of the arc-shaped guide groove is better than that of a flat surface, and can better weaken the impact force brought by the water flow.

[0031] Specifically, the first-level water distribution member 201 may also be provided with a vertical guide groove 2014 , and the shape of the guide groove 2014 is selected according to usage conditions.

[0032] Furthermore, the secondary water distribution member 202 is in the shape of a hollow frustum.

[0033] The secondary water distribution member 202 is shaped like a hollow frustum, which performs secondary diversion of the water flow passing through the primary water distribution member 201, ensuring that the water flow in the water pipe 10 is completely diverted and avoiding the occurrence of water hammer effect. In addition, the secondary water distribution member 202 is provided with a hollow frustum, which can reduce the load of the supporting device of the secondary water distribution member 202. The diameter of the hollow area in the middle of the hollow frustum is equal to the diameter of the primary water distribution member 201.

[0034] In a preferred embodiment, a fixing member 30 is further included, and the fixing member 30 is connected to the rotating shaft 2013 and the secondary water distribution member 202.

[0035] The fixing member 30 is used to fix the rotating shaft 2013, thereby fixing the position of the first-level water distribution member 201. When the water flow is too strong, the fixing effect of the rotating shaft 2013 is insufficient, causing the first-level water distribution member 201 to be displaced, resulting in the first-level water distribution member 201 and the second-level water distribution member 202 being arranged non-concentrically. As a result, the water diverted by the first-level water distribution member 201 cannot reach the second-level water distribution member 202. In this case, the fixing member 30 is provided to fix the rotating shaft 2013, preventing the rotating shaft 2013 from changing position under the impact of the water flow, thereby causing the first-level water distribution member 201 to also be displaced.

[0036] In a specific embodiment, the fixing member 30 includes a plurality of limiting rods, one end of each limiting rod is connected around the secondary water distribution member 202 , and the other end is connected to the rotating shaft 2013 .

[0037] During use, the number of limit rods to be used is determined based on the diameter of the water pipe 10 and the magnitude of the water flow. One end of the limit rod is connected to the surface of the secondary water distribution member 202, and the other end is connected to the end of the rotating shaft 2013. This is equivalent to a secondary fixation of the primary water distribution member 201. The shape of the limit rod matches the outer surface of the primary water distribution member 201 and is larger than the primary water distribution member 201. If the limit rod is in close contact with the primary water distribution member 201, the primary water distribution member 201 will be unable to rotate. The distribution of the limit rods is similar to the shape of an umbrella frame. While improving the stability of the primary water distribution member 201, it can also block a portion of the water flow, change the direction of the water flow, and thus offset some of the impact force caused by the water flow.

[0038] The above disclosure is only a preferred embodiment of the present invention, and it is certainly not intended to limit the scope of the rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the present invention.
