Description

Technical Field

[0001] The present application relates to the technical field of liquid cooling equipment, and in particular to a valve that can be used for curved pipelines. In addition, the present application also relates to a liquid cooling pipeline including the valve and a liquid cooling system including the liquid cooling pipeline. Background Art

[0002] In a liquid cooling system, in order to maintain the filter without shutting down the system, manual butterfly valves are usually installed at the front and rear ends of the filter pipeline. At the same time, a bypass pipeline is provided with a manual butterfly valve. By switching the bypass pipeline and the filter pipeline, the filter can be maintained without shutting down.

[0003] In the process of implementing this application, the inventors found that there are at least the following technical problems in the prior art:

[0004] The bypass line is connected to the filter line through an elbow. After the coolant flows through the elbow, the flow velocity, flow direction and pressure distribution will change due to the centrifugal force of the fluid in the elbow, which may cause turbulence of the fluid within a length range of about five times the pipe diameter. If a manual butterfly valve is set within this range, the valve plate of the butterfly valve is not set properly, and the fluid pressure on both sides of the valve plate is different. The unstable pressure difference causes uneven force on both sides of the valve plate, resulting in reciprocating swing. After the system has been running for a period of time, the sleeve of the valve plate is worn, causing damage to the butterfly valve. If the manual butterfly valve is set after a length of five times the pipe diameter of the elbow, the pipeline will be too long and difficult to arrange in the liquid cooling system.

[0005] Therefore, in view of the above technical problems, how to arrange the valve in the area where the bend generates turbulence and make the forces on both sides of the valve plate balanced when the fluid flows through is a technical problem that technical personnel in this field need to solve.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0039] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figure 1As shown, the fluid enters the pipeline from the bend and moves in the direction of the valve. If the bend is bent at 90°, the valve plate 11 is in a fully open state, and the plane where the valve plate 11 is located is perpendicular to the bending direction of the bend. After the fluid enters the bend, the flow rate changes due to the different bending radii at the bend of the bend. At the same time, the bend can also change the flow direction of the fluid. Therefore, under the influence of various influencing factors, the fluid will be turbulent within a certain length range after flowing out of the bend, which is referred to as the turbulent area. If the valve is located in the turbulent area, when the fluid flows through area a and area b respectively, the flow direction of the fluid does not completely move along the axial direction of the valve body, and under different flow rates, it will have a certain impact on the end face of the valve plate 11. Affected by the change in flow rate, the impact strength of the fluid in area a and area b will also be different, which will cause different pressures on the valve plate 11 in area a and area b, so that the force on the valve plate 11 is unbalanced, causing the valve plate 11 to swing back and forth, thereby increasing the risk of wear of the sleeve. If a valve is installed at a long distance after the bend, the overall structure of the pipeline will be too long, affecting its layout inside the liquid cooling system. For example, if the diameter of the bend is 90mm, the valve needs to be installed 450mm after the bend. For a liquid cooling system with a height of usually 2000mm, it will affect the layout of other components. Based on the above situation, the present application proposes a valve that can be used for a bent pipeline. The valve can be installed in the turbulent area after the bend, and the forces on both sides of the valve plate 11 are balanced.

[0041] Please refer to Figure 2 In this embodiment, a valve that can be used for a curved pipeline is provided. The valve 1 of the present application includes a valve body 12 and a valve plate 11. The valve plate 11 and the valve body 12 rotate in cooperation to realize the opening and closing of the pipeline. The connecting end of the valve body 12 is connected to the pipe 2 to form a circulating pipeline. Since the valve 1 of the present application is for a curved pipeline, at least one side of the pipeline on the side of the valve plate 11 is curved, that is, at least a corresponding curved pipeline needs to exist on one side of the valve plate 11, and the valve 1 is located in the turbulent area of ​​the curved pipeline, specifically, the valve plate 11 is located in the turbulent area. When the valve plate 11 rotates to open the pipeline, the valve plate 11 has a rotation position so that the plane where the valve plate 11 is located is parallel to the bending direction of the pipeline.

[0042] When the plane of the valve plate 11 is parallel to the bending direction of the pipeline, if the fluid flows along the curved pipeline toward the valve plate 11 at a certain initial velocity, the flow direction of the fluid does not completely move along the axial direction of the valve body 12, and the flow velocity will also have a certain difference (affected by the different bending radii inside the curved pipeline), but the flow effect of the fluid will be roughly symmetrically distributed on both sides of the valve plate 11, please refer to Figure 3 That is to say, when the fluid passes through area c and area d, the flow pattern of the fluid in the two areas is roughly symmetrical, and the flow pattern includes flow velocity, flow direction, etc.

[0043] Specifically, when fluid passes through one end of a curved pipeline, the pressure exerted by the fluid on the outer wall of the pipeline becomes greater and greater due to the compression of the fluid by the outer wall of the pipeline; on the side of the inner wall of the pipeline, the pressure exerted by the fluid on the pipeline becomes smaller and smaller; when the fluid flows through the apex of the bend in the pipeline, the pressure difference between the inner and outer walls of the pipeline section is the largest, and then the pressure on the inner and outer walls of the pipeline caused by the fluid flow begins to change in opposite directions, that is, the pressure exerted by the fluid on the outer wall of the pipeline becomes smaller and smaller, and the pressure exerted on the inner wall of the pipeline becomes larger and larger. Therefore, during this pressure difference change process, the fluid will produce a certain turbulence inside, but the turbulence effect is caused by the bend of the pipeline.

[0044] The outer wall and inner wall are two pipe walls with the same diameter on the same cross-sectional circle of the curved pipeline, of which the one close to the inside of the pipeline is called the inner wall, and the one close to the outside of the pipeline is called the outer wall. When the pressure of the fluid on the outer wall and the inner wall is different, the fluid will have a tendency to flow toward the center of the cross-sectional circle inside the pipeline, and this tendency will be weakened to a certain extent when entering the valve body 12, but it will not disappear, and this tendency is symmetrically distributed along the plane where the axis of the pipeline after bending is located, and the plane where the axis of the pipeline is located is related to the bending direction of the pipeline, that is, the axis 21 of the pipeline before bending and the axis 22 of the pipeline after bending form a plane.

[0045] The valve plate 11 of the present application rotates to achieve the plane where the valve plate 11 is parallel to the bending direction of the pipeline, including two situations:

[0046] One is that the pipeline is bent at 90°, that is, the axis 22 after the bending is parallel to the rotation axis of the valve plate 11. At this time, when the valve plate 11 rotates with its rotation axis, the plane where the valve plate 11 is located can always be parallel to the axis 22 after the bending, but only when the valve plate 11 is rotated to coincide with the axis 21 before the bending, can it coincide with the plane where the axis of the pipeline after the bending is located. At this time, the valve 1 is in a fully open state, and the plane where the valve plate 11 is located is also located in the plane where the axis of the pipeline after the bending is located. At this time, the fluid movement forms in the c area and the d area on both sides of the valve plate 11 are symmetrically distributed, and the pressure on both sides of the valve plate 11 is balanced.

[0047] The other is that the pipeline is bent at an obtuse angle or an acute angle, for example, the bending angle is 45°, 60°, 120°, 135° and other special angles. At this time, when the valve 1 is fully closed, the plane where the valve plate 11 is located intersects with the axis 22 after the bend. Only when the valve plate 11 continues to rotate until it coincides with the axis 21 before the bend, will the plane where the valve plate 11 is located coincide with the plane where the axis of the pipeline after the bend is located. At this time, the valve 1 is in a fully open state, and the plane where the valve plate 11 is located is also located on the plane where the axis of the pipeline after the bend is located. At this time, the fluid movement forms in the c area and the d area on both sides of the valve plate 11 are symmetrically distributed, and the pressure on both sides of the valve plate 11 is balanced.

[0048] For the above two situations, the rotation axis of the valve plate 11 needs to be located in the plane where the axis of the pipeline is located after bending, or parallel to the plane where the axis of the pipeline is located after the pipeline is bent, so as to ensure that when the valve 1 is fully open, the valve plate 11 can coincide with the plane where the axis of the pipeline is located after bending.

[0049] It should be pointed out that the bending direction of the pipeline of the present application is the same as the direction of the axis 22 after bending, but the bending direction only represents the direction of an orientation and is not limited to a direction of a similar axis at a specific position. Therefore, when the plane where the valve plate 11 is located is parallel to the bending direction of the pipeline, it includes the parallelism of the axis 22 after bending and the plane where the valve plate 11 is located, and the coincidence of the axis 22 after bending and the plane where the valve plate 11 is located. Of course, the present application is introduced based on the example that the axis 22 after bending coincides with the plane where the valve plate 11 is located, but the parallelism of the axis 22 after bending and the plane where the valve plate 11 is located also falls within the protection scope of the present application, and its effect can obviously reduce the pressure difference on both sides of the valve plate 11 compared with the prior art, thereby reducing the reciprocating swing of the valve plate 11 when the flow passes through the valve body 12, and improving the service life.

[0050] In addition, the above-mentioned pre-bending axis 21 and post-bending axis 22 are relative, that is, after the pipe is bent, any one side can be defined as the pre-bending state, and the corresponding axis is the pre-bending axis 21; the other side is defined as the post-bending state, and the corresponding axis is the post-bending axis 22. Figure 2 , the valve 1 of the present application is located at the intersection of the pipeline before bending and the bending area, at this time, the bending direction of the pipeline after bending is defined as the bending direction of the pipeline; similarly, if Figure 2 If the front bending axis 21 and the rear bending axis 22 are interchanged, the valve 1 is located at the intersection of the pipeline after bending and the bending area, and the bending direction of the pipeline before bending is defined as the bending direction of the pipeline. In other words, the front bending axis 21 and the rear bending axis 22 are only used to provide a clear reference for the valve plate 11 and the valve stem 15, so as to determine the position and state of the plane of the valve plate 11 and the axis of the valve stem 15 based on the reference reference, and no specific restrictions are imposed on the pipeline before or after bending.

[0051] In summary of the above embodiments, the valve 1 is aimed at a pipeline with a curved section, that is, there is a corresponding pipeline with a curved setting on at least one side of the valve plate 11, and the rotation of the valve plate 11 will cause the valve plate 11 to be in a position so that the plane where the valve plate 11 is located is parallel to the bending direction of the pipeline. At this time, the valve 1 is in an open state (including a fully open state), and the fluid moves from the pipeline to the valve plate 11. After the fluid passes through the curved pipeline, the flow velocity change and pressure change caused by the centrifugal force of the fluid will be evenly distributed to the open circuit on both sides of the valve plate 11, so that the force on both sides of the valve plate 11 is even, which can avoid damage to the valve 1. At the same time, the valve 1 can be arranged in the area where the curved pipeline generates turbulence, shortening the length of the entire pipeline, making the structure in the length direction of the pipeline more compact, and facilitating its arrangement inside the liquid cooling system.

[0052] Please refer to Figure 4 and Figure 5 , the valve plate 11 is rotatably set on the valve body 12 through the valve stem 15, and the valve plate 11 rotates with the axis of the valve stem 15 as the rotation axis. For the concentric butterfly valve, the axis of the valve stem 15 coincides with the plane where the valve plate 11 is located. At this time, in order to ensure that the valve plate 11 can coincide with the plane where the axis of the pipeline after bending is located after rotation, the axis of the valve stem 15 needs to be set in the plane where the axis of the pipeline after bending is located. For the eccentric butterfly valve, the axis of the valve stem 15 is parallel to the plane where the valve plate 11 is located. At this time, it is not necessary to set the axis of the valve stem 15 in the plane where the axis of the pipeline after bending is located. It is only necessary to set the axis of the valve plate 11 parallel to the plane where the axis of the pipeline after bending is located, and ensure that when the valve 1 is rotated to the fully open state, the plane where the valve plate 11 is located coincides with the plane where the axis of the pipeline after bending is located.

[0053] In addition, the valve 1 also includes a handle 14 located outside the valve body 12, see Figure 4 , the handle 14 is connected to the valve stem 15 to drive the valve stem 15 to rotate relative to the valve body 12, and a shaft sleeve 16 is sleeved at the connection between the valve stem 15 and the valve body 12. As for the fluid pipeline, a sealing ring 13 (not shown in the figure) is usually required to be provided at the connection between the valve 1 and the pipeline 2, and a sealing ring 13 is provided at the contact between the valve plate 11 and the valve seat or the valve body 12 to form a fully closed seal. Similarly, a sealing component is also provided at the shaft sleeve 16 of the valve stem 15 to realize the rotational seal between the valve stem 15 and the valve body 12. As for the specific form of the above-mentioned sealing member, it will not be repeated here, and reference can be made to the prior art.

[0054] In addition, the valve 1 of the present application is installed in conjunction with the pipeline through a limiting mechanism, and the limiting mechanism includes a plurality of V-shaped plates 7, which are placed on a reference platform to provide a stable assembly plane; the plurality of V-shaped plates 7 can be used to achieve the coaxiality of the valve 1 and the pipeline, and the axis of the valve plate 11 is parallel to or coincides with the plane where the axis of the pipeline is located after bending. Please refer to Fig. 9, where two V-shaped plates 7 are used to support the two ends of the curved section of the pipeline, and the V-shaped groove of the V-shaped plate 7 is limited against the outer periphery of the pipeline. The ground or other supporting platform can be used as a reference platform, and the V-shaped plate 7 can be placed on the reference platform, so that the pipeline is parallel to the reference platform, that is, the plane where the axis of the pipeline after bending is located is parallel to the reference platform. When installing the valve 1, another V-shaped plate 7 is used to support the outer periphery of the valve 1 or the valve body 12, and the V-shaped groove of the V-shaped plate 7 is limited against the outer periphery of the valve 1 or the valve body 12 to ensure that the axis of the valve 1 is coaxial with the pipeline; at the same time, the V-shaped plate 7 set at the exposed part of the handle 14 or the valve stem 15 is used, and the V-shaped groove of the V-shaped plate 7 is limited against the outer periphery of the handle 14 or the valve stem 15 to adjust the axis position of the valve stem 15 and the valve plate 11, so that the axis of the valve plate 11 and the valve stem 15 can also be parallel to the reference platform. On this basis, the four V-shaped plates 7 can ensure that when the valve plate 11 is opened, the plane of the valve plate 11 is parallel to or coincides with the plane of the axis of the bent pipeline, thereby reducing the pressure difference on both sides of the valve plate 11 and extending the service life of the valve 1.

[0055] By utilizing the V-groove structure of the V-shaped plate 7, the pipeline can be placed parallel to the reference platform under the limitation of the V-groove structure. Under the limitation support of the V-groove structure, the valve 1 can be coaxially arranged with the pipeline, and under the limitation support of the V-groove structure, the axis of the valve stem 15 can be limited. Therefore, under the premise of reasonably setting the size of the V-shaped plate 7, the valve 1 can be accurately coaxially arranged with the pipeline, and the axis of the valve plate 11 can be parallel to or coincide with the plane where the axis of the pipeline after bending is located.

[0056] As for the rotation angle of the handle 14, a limit sleeve 17 can be sleeved on the outer periphery of the exposed part of the valve stem 15, the limit sleeve 17 is fixed on the valve body 12, and a notch is set on the limit sleeve 17, and the handle 14 can rotate in the notch, so as to ensure that the handle 14 can drive the valve plate 11 to switch between the fully closed state and the fully open state. Of course, the limit range of the notch can also be set between 0°-90°, that is, 0° corresponds to the fully closed state of the valve 1, and 90° corresponds to the fully open state of the valve 1, so that the valve plate 11 can accurately reach the fully open or fully closed state.

[0057] In some embodiments, the curved pipeline can be formed by the pipe 2 at the connecting end of the valve body 12, that is, the pipe 2 itself is bent to form a curved pipeline. Of course, there are also some valve bodies 12 whose connecting ends have been bent into shape, so both can be called curved pipelines.

[0058] In this embodiment, the bending of the pipe 2 is taken as an example for description, and the bending of the valve body 12 itself can also refer to the embodiment of the bending of the pipe 2. For a butterfly valve, the axis of its valve stem 15 is usually arranged perpendicular to the axis of the valve body 12, and when the plane where the valve plate 11 is located is perpendicular to the axis of the valve body 12, it is in a fully closed state; when the plane where the valve plate 11 is located is parallel to the axis of the valve body 12, it is in a fully open state.

[0059] Further, the bending angle of the pipe 2 is preferably 90°, and can also be an obtuse angle or an acute angle, which will not be described here, and please refer to the above embodiment. The pipe 2 is a cylindrical pipe, and the axis of the valve stem 15 is preferably parallel to the bending direction of the pipe 2.

[0060] In addition, the above embodiment points out that a curved pipeline is set on at least one side of the valve plate 11. Of course, the pipelines on both sides of the valve plate 11 can also be set as curved pipelines, but it is necessary to ensure that the valve body 12 is at least located at the rear end of the curved pipeline 2. The rear end here is based on the direction of fluid flow, that is, the front end is the first flow through of the fluid, and the rear end is the later flow through, so that the fluid flows from the curved pipeline 2 to the valve plate 11.

[0061] There are many kinds of bending forms of the pipeline. For example, there can be multiple bends in the pipeline. However, the curved pipeline referred to in this application only refers to the curved section closest to the valve plate 11. The turbulence formed by other curved sections will eventually be affected by the curved section closest to the valve plate 11, so that the fluid will be turbulent based on the curved section closest to the valve plate 11 and flow through the valve 1.

[0062] The present application also discloses a liquid cooling pipeline, including a filter pipeline 4, on which a filter 6 is arranged to filter the coolant, and a corresponding elbow 3 is arranged on the inlet side and / or the outlet side of the filter 6, please refer to Figure 6 and Figure 7 The valve 1 is also arranged at the rear end of the curved pipe 3 so that the fluid flows from the curved pipe 3 to the valve 1. The valve 1 is any of the above-mentioned valves that can be used for curved pipelines.

[0063] In other words, for a pipeline with a curved section, when a valve 1 needs to be installed in the pipeline, the valve 1 that can be used for a curved pipeline of the present application can be used, thereby reducing the impact of the turbulence generated by the curved pipe 3 on the life of the valve 1, while shortening the length of the entire pipeline as much as possible to make the structure more compact.

[0064] In addition, the liquid cooling pipeline also includes a bypass pipeline 5, which is arranged in parallel with the filter pipeline 4, and a valve 1 is arranged on the bypass pipeline 5. Figure 6 and Figure 7 It can be seen that a bend pipe 3 is provided on the inlet side of the filter 6, one end of the bend pipe 3 is connected to the bypass pipeline 5, and a valve 1 is provided at the other end (rear end) of the bend pipe 3, thereby ensuring the connection effect with the filter 6, and at the same time having all the advantages of the above-mentioned valve 1 that can be used for the bent pipeline.

[0065] The outlet side of the filter 6 is connected with another elbow 3, the rear end of which is connected with the main pipeline through a valve 1, and the bypass pipeline 5 is also connected with the main pipeline, thereby forming a liquid cooling pipeline for non-stop maintenance.

[0066] In addition, the number of filter lines 4 can be at least two, see Figure 8 , and multiple filter pipes 4 are arranged in parallel. The arrangement forms of multiple filter pipes 4 are roughly the same, and the difference is only in the number and form of the elbows 3 arranged on the inlet side or outlet side of different filters 6. They will not be described in detail here. It is sufficient to ensure that the valve 1 of the present application is located at the rear end of the elbow 3 and should be arranged as close to the elbow 3 as possible, so as to save a pipe about ten times the diameter of the elbow 3.

[0067] In addition, the present application also provides a liquid cooling system, which includes any of the above-mentioned liquid cooling pipelines. Therefore, the liquid cooling system also has the advantages of long service life of the valve 1, stable effect, compact structure, and is convenient for the arrangement and installation of itself and other components.
