[0002] Plane valves are a common type of fluid control valve, widely used in chemical, environmental protection, and water treatment industries. They are mainly used to control the on / off state and flow direction of multiple fluids.

[0003] Currently, common planar valve structures typically employ multiple independent valve bodies to achieve multi-channel switching in order to control multiple fluids. However, this setup results in complex parallel connections of various valve pipes and requires precise electronic control components, leading to a complex structure, high manufacturing and maintenance costs, and making it unsuitable for high-frequency switching and stable switching environments.

[0014] Preferably, the transposition port one and transposition port two are arranged alternately, and the through port one and through port two are arranged alternately.

[0015] Preferably, the valve core includes a core plate, and a cavity plate is fixedly installed on the surface of the core plate. The core plate and the cavity plate together form a hollow transposition cavity inside the core plate.

[0016] Preferably, one end of the transposition cavity is connected to the first transposition port two, which penetrates one side of the core plate, and the other end of the transposition cavity is connected to the second transposition port two, which penetrates the other side of the core plate.

[0041] Example

[0042] Please refer to Figures 1-5 This utility model provides a four-position, one-rotation planar valve for adjusting the flow direction and flow rate of four pipeline positions. It includes an upper valve body 1, a valve ring 5, a valve core 6, a lower valve body 7, and a lower valve cover 3, which are installed together in sequence. The upper valve body 1, valve ring 5, lower valve body 7, and lower valve cover 3 are fixedly attached to each other. The valve core 6 is coaxially rotatably disposed in the valve ring 5. The outer edge of the valve core 6 contacts the rotating surface of the drive shaft 8. One end of the drive shaft 8 passes through the valve ring 5 and the upper valve body 1 and is coaxially fixedly connected to an external motor drive shaft to drive the valve core 6 to rotate.

[0043] The upper valve body 1 has four fluid inlets 2 that are connected to different fluid pipes, which in turn are connected to the tanks of the corresponding workstations.

[0044] Please refer to the following: Figure 2 and Figure 9 The valve core 6 includes a core plate 61, a first switching port 62, a second switching port 63, a switching cavity 64, and a cavity plate 65.

[0045] Specifically, the core plate 61 is rotatably mounted inside the valve ring 5. The two sides of the valve ring 5 are respectively attached to the surfaces of the upper valve body 1 and the lower valve body 7, restricting the displacement of the core plate 61. Two transposition ports 62 are passed through the core plate 61, and the positions of the transposition ports 62 correspond to the projected positions of the four fluid inlets 2 of the upper valve body 1. A cavity plate 65 is fixedly installed on the surface of the core plate 61. The core plate 61 and the cavity plate 65 together form a hollow transposition cavity 64 inside the core plate 61. One end of the transposition cavity 64 is connected to a transposition port 63, which passes through one side of the core plate 61. The other end of the transposition cavity 64 is connected to another transposition port 63, which passes through the other side of the core plate 61, so that the relative positions of the two transposition ports 63 are misaligned.

[0046] The core plate 61 has two transposition ports 62 and two transposition ports 63 on each side. The four transposition ports are evenly distributed on the core plate 61 with the center of the core plate 61 as the center. The fluid inlet 2 on the upper valve body 1 is also evenly distributed on the upper valve body 1 with the center of the upper valve body 1 as the center.

[0047] The drive shaft 8 that drives the valve core 6 to rotate includes a snap-fit ​​shaft 81, a pin 82, and a roller 83. One end of the snap-fit ​​shaft 81 is snapped and fixed to the drive shaft of an external motor (such as a keyway snap-fit), and the other end of the snap-fit ​​shaft 81 is set as a pin 82. The pin 82 is rotatably mounted on the lower valve body 7. The roller 83 is coaxially fixed on the snap-fit ​​shaft 81. The rolling surface of the roller 83 is a rough surface, and the rolling surface is in frictional contact with the outer edge surface of the core plate 61. When the motor starts, the drive shaft 8 can drive the core plate 61 to rotate, thereby changing the position of each shifting port on the core plate 61.

[0048] For preferred options, please refer to [the provided text]. Figure 4 and Figure 5 When the four workstation tanks are not transmitting fluid, the positions of the switching ports 62 and 63 on the core plate 61 do not correspond to the positions of the four fluid inlets 2 of the upper valve body 1, thus realizing the sealing function of the planar valve structure. When the four workstation tanks are transmitting fluid, the positions of the two switching ports 62 and 63 on the core plate 61 correspond one-to-one with the positions of the four fluid inlets 2 of the upper valve body 1. When different fluid channels are switched during fluid transmission, the valve core 6 is rotated one-quarter turn each time by the motor control, so that the switching ports 62 and 63 leave the current fluid inlet 2 and are matched with the next adjacent fluid inlet 2, thus realizing the function of switching ports 62 and 63 switching to connect to different fluid inlets 2.

[0049] Preferably, after each quarter turn of the valve core 6, each fluid inlet 2 can connect to the switching port 1 62 and switching port 2 63 at different positions. Each switching port 1 62 and switching port 2 63 is independently connected, so that each fluid inlet 2 can be aligned and connected with four separate channels. After each number of rotations of the valve core 6, the fluid inlets 2 of the four workstation tanks can be aligned and connected with all the holes, thus completing the adjustment of the valve flow direction.

[0050] Furthermore, the lower valve body 7 includes a valve body plate 71, a first port 72, a second port 73, a first flow channel cavity 74, and a second flow channel cavity 75.

[0051] For details, please refer to Figures 10-13 In this embodiment, the valve ring 5 and the lower valve cover 3 are respectively attached and fixed on both sides of the valve body plate 71. Two flow channel cavities 1 74 and two flow channel cavities 2 75 are opened at the joint surface of the valve body plate 71 and the lower valve cover 3. The attached valve body plate 71 and the lower valve cover 3 form hollow and sealed flow channel cavities 1 74 and 2 75.

[0052] Each flow channel cavity 74 on the valve body plate 71 has a through port 72 at both ends, and each flow channel cavity 75 has a through port 73 at both ends. The through ports 72 and 73 penetrate the surface of the valve body plate 71.

[0053] Each flow channel cavity 74 on the lower valve cover 3 is provided with an outlet channel 41, and each flow channel cavity 75 is provided with an outlet channel 42. The outlet channel 41 and the outlet channel 42 pass through the plate surface of the lower valve cover 3.

[0054] Please refer to the following: Figure 2 The four through ports 72 on the valve body plate 71 are evenly distributed around the center of the valve body plate 71, and the position of the through ports 72 corresponds to the projected position of the shift port 62 on the valve core 6; the four through ports 73 on the valve body plate 71 are evenly distributed around the center of the valve body plate 71, and the position of the through ports 73 corresponds to the projected position of the shift port 63 that penetrates the lower plate surface on the valve core 6.

[0055] For preferred options, please refer to [the provided text]. Figure 2 and Figure 11 The four ports 1 72 and four ports 2 73 on the valve body plate 71 are arranged in staggered relative positions. When the valve core 6 rotates to flow passage, the two switching ports 1 62 are respectively connected to the ports 1 72 at the upper end of the two flow channel cavities 1 74, and the two switching ports 2 63 are respectively connected to the ports 2 73 at the upper end of the two flow channel cavities 2 75, so that the four flow channel inlets are respectively connected to individual flow channel cavities.

[0056] Preferably, when adjusting the flow direction, after the valve core 6 rotates to a quarter turn, the two switching ports 62 rotate to the other end of the corresponding flow channel cavity 74. At this time, the switching ports 62 are still connected to the flow channel cavity 74 before rotation, and the flow direction of the two switching ports 62 will not change. The two switching ports 63 rotate to the other end of the flow channel cavity 75, and the flow channel cavity 75 connected to the two switching ports 63 is interchanged, so that the flow direction of the two switching ports 63 is interchanged.

[0057] Preferably, after the valve core 6 continues to rotate to half a turn, the two switching ports 63 rotate to the other end of the current flow channel cavity 75. At this time, the switching ports 63 are still connected to the current flow channel cavity 75, and the flow direction of the two switching ports 63 will not change. Meanwhile, the two switching ports 62 rotate to the other end of the flow channel cavity 74. At this time, the flow channels 74 connected to the two switching ports 62 are interchanged, so that the flow direction of the two switching ports 62 is interchanged.

[0058] Preferably, the combination of the upper valve body 1 and the valve core 6 allows for adjustment of the flow direction of all four fluid inlets 2. However, each time the valve core 6 is rotated (one-quarter turn), each fluid inlet 2 will simultaneously connect to different switching ports, adjusting the flow direction in all four directions. Conversely, the combination of the valve core 6 and the lower valve body 7 ensures that each time the valve core 6 is rotated (one-quarter turn), only the flow direction of any two fluid inlets 2 will change (e.g., simultaneously connecting the two fluid inlets 2 at port 1 72, or simultaneously connecting the two fluid inlets 2 at port 2 73), without changing the overall flow direction. This allows operators to specifically adjust the flow direction of two corresponding fluid inlets 2 when adjusting the flow direction of the planar valve.

[0059] It is worth noting that, please refer to Figures 6-8 When the switching port 62 of the valve core 6 rotates to connect with the fluid inlet 2, the switching port 62 connects with the through port 72, thereby connecting to the outlet channel 41 through the flow channel cavity 74; when the switching port 63 of the valve core 6 rotates to connect with the fluid inlet 2, the switching port 63 connects with the through port 73, thereby connecting to the outlet channel 42 through the flow channel cavity 75.

[0060] It is worth noting that the fluid outlet 4 is set as either outlet channel one 41 or outlet channel two 42. The orifice diameter of outlet channel one 41 is larger than that of outlet channel two 42, so that the fluid flow rate through different outlet channels changes. This allows the unit flow rate of each fluid entering from the inlet of the flow channel to be switched simultaneously when the plane valve switches the flow direction of the flow channel inlet.

[0061] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
