Description

Technical Field

[0001] This invention relates to the field of water valve technology, and in particular to a cylindrical rotating water valve. Background Technology

[0002] Hydraulic transmission, as a type of hydraulic transmission, is widely used in industries such as engineering machinery, machine tools, automobiles, mining equipment, aerospace, and medical. Hydraulic transmission uses water as the medium, and water valves are essential in both transmission and control. Water, unlike hydraulic oil, generally lacks lubrication and kinematic viscosity, requiring high sealing performance and prone to leakage. It also easily corrodes components in contact with water. Therefore, the sealing performance of water valves is a crucial parameter. Traditional water valves with good sealing performance include ball valves and butterfly valves. Ball valves are particularly common for controlling fluids containing fibers or small solid particles. However, traditional ball valves require the valve stem to rotate the opening and closing element (ball) 90 degrees from fully open to fully closed. For applications requiring immediate shut-off or immediate opening, the opening and closing speed of traditional ball valves cannot meet the requirements. Summary of the Invention

[0003] Therefore, it is necessary to provide a cylindrical rotary water valve with good sealing performance and rapid opening and closing.

[0004] A cylindrical rotary water valve, comprising:

[0005] The valve body has a rotating cavity, a water outlet channel, a water passage hole, a connecting hole, and a water inlet channel inside; the water passage hole is connected to the rotating cavity and the water outlet channel respectively; the connecting hole is connected to the rotating cavity and the water inlet channel respectively; the side wall of the valve body has an operating hole that communicates with the rotating cavity;

[0006] A columnar sealing valve core is rotatably disposed within the rotating cavity; the sealing valve core has a conduction channel with openings at both ends; the opening directions at both ends of the conduction channel intersect.

[0007] The valve stem has one end located outside the valve body and the other end passing through the operating hole and connected to the sealing valve core;

[0008] The driving mechanism is connected to one end of the valve stem located outside the valve body and is used to drive the valve stem to rotate the sealing valve core around its own central axis in a forward or reverse direction by a preset angle, so that the two ends of the guiding channel are respectively aligned with the water passage and the connecting hole, or the opening of the guiding channel at the end away from the water inlet channel is completely offset from the water passage.

[0009] The water passage is an elongated through hole whose long axis is aligned with the axial direction of the sealing valve core, and the guiding channel is a flattened channel extending along the axial direction of the sealing valve core.

[0010] In one embodiment, there are multiple water passage holes, and the multiple water passage holes are spaced apart along a direction perpendicular to the longitudinal direction of the sealing valve core.

[0011] The guiding channel includes an inlet section and multiple outlet sections that correspond one-to-one with the multiple water passages; the multiple outlet sections are all connected to the outlet channel; after the sealing valve core rotates a preset angle around its own central axis in the forward direction, the multiple outlet sections are aligned one-to-one with the multiple water passages, and the inlet section is aligned with the connecting hole; after the sealing valve core rotates a preset angle in the reverse direction around its own central axis, each outlet section is completely offset from all the water passages.

[0012] In one embodiment, the water outlet channel includes a rectangular through groove and a circular through hole communicating with the rectangular through groove; the rectangular through groove is connected to the water passage hole; on a plane perpendicular to the central axis of the circular through hole, the orthographic projection of the rectangular through groove completely covers the orthographic projection of the circular through hole and the water passage hole.

[0013] In one embodiment, the liquid flow direction in the inlet section is perpendicular to the liquid flow direction in the outlet section; the inlet channel is located below the rotating cavity.

[0014] In one embodiment, the valve body includes a valve block, an end cap, and a valve seat; the valve block has the water inlet channel, the operating hole, and a mounting groove with one end open; the mounting groove communicates with the water inlet channel and the operating hole respectively; the valve seat is disposed in the mounting groove and has the rotating cavity, the water passage hole, the connecting hole, and a through hole aligned with and communicating with the operating hole; the end cap covers the opening of the mounting groove and is detachably connected to the valve block to press the valve seat tightly in the mounting groove; the end cap forms the water outlet channel at a position opposite to the water passage hole; one end of the sealing valve core passes through the operating hole and the through hole in sequence and is connected to the sealing valve core.

[0015] In one embodiment, the valve seat includes a first seat body and a second seat body; a first arcuate groove is formed inward on one side surface of the first seat body; a water passage hole penetrating the first seat body is provided at the bottom of the first arcuate groove; a second arcuate groove is formed inward on one side surface of the second seat body; a through hole penetrating the second seat body is provided at the bottom of the second arcuate groove; the first seat body and the second seat body are spaced apart in the mounting groove along the direction from the opening of the mounting groove to the operating hole, and the first arcuate groove and the second arcuate groove form the rotating cavity; the gap between the first seat body and the second seat body located below the rotating cavity serves as the communicating hole; the end of the end cap facing the rotating cavity abuts against the first seat body.

[0016] In one embodiment, the first base and the second base are arranged parallel to each other and spaced apart along the direction from the opening of the mounting groove toward the operating hole.

[0017] In one embodiment, the end cap is provided with a supporting portion along the circumference of the water outlet channel on the side facing the rotating cavity; the supporting portion extends into the mounting groove and abuts against the end of the first seat body opposite to the second seat body.

[0018] In one embodiment, the water inlet channel extends axially along the sealing valve core; there are multiple rotating chambers; the multiple rotating chambers are spaced apart along the extension direction of the water inlet channel; the number of the water outlet channel, the water passage hole, the connecting hole and the operating hole are all multiple, each corresponding to one of the multiple rotating chambers;

[0019] There are multiple sealing valve cores, valve stems, and driving mechanisms; the multiple sealing valve cores are respectively arranged in multiple rotating cavities; the multiple valve stems are respectively inserted through the operating holes; one end of each valve stem is connected to the corresponding sealing valve core, and the other end is connected to the corresponding driving mechanism.

[0020] In one embodiment, it further includes a base and a movable component; the driving mechanism is a telescopic cylinder; the valve body and the telescopic cylinder are both mounted on the base; the valve stem has an axially oriented hole at one end away from the rotating cavity; the movable end of the telescopic cylinder has a positioning hole; the movable component passes through the axially oriented hole and connects to the positioning hole.

[0021] The aforementioned cylindrical rotary water valve is in the open state when both ends of the conduction channel are aligned with the water passage and the connecting hole, respectively; it is in the closed state when the opening at the end of the conduction channel away from the inlet channel is completely offset from the water passage. During use, to switch the cylindrical rotary water valve between the open and closed states, simply use the drive mechanism to drive the valve stem to rotate the sealing valve core forward or backward by a preset angle. Furthermore, because the sealing valve core has a cylindrical structure, and the conduction channel is a flat channel extending axially along the sealing valve core, while the water passage is a long, narrow through-hole with its major axis aligned with the axial direction of the sealing valve core, the sealing valve core only needs to rotate a very small angle. Therefore, the aforementioned cylindrical rotary water valve combines the advantages of large water flow and rapid opening and closing, fully meeting the requirements of applications requiring immediate shut-off and opening.

[0038] Figure 1 The diagram illustrates the structure of a cylindrical rotary water valve according to one embodiment of the present invention. For ease of explanation, the accompanying drawings only show structures relevant to embodiments of the present invention.

[0039] Please see Figures 1 to 3In a preferred embodiment of the present invention, the cylindrical rotary water valve 100 includes a valve body 110, a sealing valve core 120, a valve stem 130, and a drive mechanism 140.

[0040] Please refer to the following: Figure 4 The valve body 110 has a rotating chamber 111, a water outlet channel 112, a water passage 113, a connecting hole 114, and a water inlet channel 115. The water passage 113 communicates with both the rotating chamber 111 and the water outlet channel 112. The connecting hole 114 communicates with both the rotating chamber 111 and the water inlet channel 115. An operating hole 116 communicating with the rotating chamber 111 is provided on the side wall of the valve body 110.

[0041] The sealing valve core 120 is cylindrical. The sealing valve core 120 is rotatably disposed within the rotating cavity 111. The sealing valve core 120 has a conducting channel 121 with openings at both ends. The opening directions at both ends of the conducting channel 121 intersect. Both openings of the conducting channel 121 are located on the cylindrical surface of the sealing valve core 120.

[0042] The sealing valve core 120 has at least one cylindrical surface (not shown). The outlet of the conduction channel 121 is located on the cylindrical surface. When the sealing valve core 120 is located in the rotating cavity 111, the cylindrical surface is in sealing contact with the inner wall of the rotating valve core 111.

[0043] When the sealing valve core 120 includes a cylindrical surface, the cross-sectional shape of the sealing valve core 120 is circular, and the side surface of the sealing valve core 120 is an annular cylindrical surface. When the cross-sectional shape of the sealing valve core 120 is non-circular, the side surface of the valve core sealing structure 120 includes a cylindrical surface and at least one non-cylindrical connecting surface. When the side surface of the sealing valve core 120 includes two or more cylindrical surfaces, the side surface of the sealing valve core 120 also includes multiple non-cylindrical connecting surfaces, with one or more non-cylindrical connecting surfaces connecting any two adjacent cylindrical surfaces. The non-cylindrical connecting surfaces can be planar, arc-shaped, corrugated, or other non-cylindrical surfaces. The shapes of the multiple non-cylindrical connecting surfaces can be all the same, partially the same, or all different.

[0044] Of course, when the side of the sealing valve core 120 includes multiple cylindrical surfaces, one end of the conduction channel 121 is located on one of the cylindrical surfaces, and the cylindrical surface is in sealing contact with the part of the inner wall of the rotating cavity 111 where the water passage hole 113 is provided, so as to reduce the probability that the liquid at the water passage hole 113 leaks along the inner wall of the rotating cavity 111 to the connecting hole 114 when the sealing valve core 120 is in a static state or in a rotating state, thus ensuring the sealing performance between the sealing valve core 120 and the inner wall of the rotating cavity 111.

[0045] One end of the valve stem 130 is located outside the valve body 110, and the other end passes through the operating hole 116 and is connected to the sealing valve core 120.

[0046] The drive mechanism 140 is connected to the valve stem 130 at one end outside the valve body 110, and is used to drive the valve stem 130 to rotate the sealing valve core 120 around its own central axis in a forward or reverse direction by a preset angle, so that the two ends of the guide channel 121 are aligned with the water passage 113 and the connecting hole 114 respectively, or the opening of the guide channel 121 away from the water inlet channel 115 is completely offset from the water passage 113.

[0047] Among them, the water passage 113 is an elongated through hole whose long diameter direction is consistent with the axial direction of the sealing valve core 120, and the conduction channel 121 is an axially extended, flat channel of the sealing valve core 120.

[0048] In actual use, when the cylindrical rotary water valve 100 is in the open state, the two ends of the conduction channel 121 are aligned with the water passage 113 and the connecting hole 114 respectively, so as to connect the water inlet channel 115 and the water outlet channel 112; when the cylindrical rotary water valve 100 is in the closed state, the end of the conduction channel 121 away from the water inlet channel 115 is completely offset from the water passage 113, so as to disconnect the water inlet channel 115 and the water outlet channel 112.

[0049] Because the sealing valve core 120 has a cylindrical structure and the conduction channel 121 is a flat channel extending along the axial direction of the sealing valve core 120, while the water passage 113 is an elongated through hole whose long axis is aligned with the axial direction of the sealing valve core 120, the dimensions of the water passage 113 and the conduction channel 121 in the circumferential direction of the sealing valve core 120 are relatively small. Therefore, the sealing valve core 120 only needs to be rotated by a very small angle to switch between the open and closed states. Thus, the above-mentioned cylindrical rotary water valve 100 has the advantages of large water flow and rapid opening and closing, which can fully meet the usage requirements of some applications that require immediate shut-off and opening.

[0050] In some embodiments, the cylindrical rotary water valve 100 further includes a base 150. The drive mechanism 140 is a telescopic cylinder. Both the valve body 110 and the telescopic cylinder are mounted on the base 150. The valve stem 130 has an oblong hole 131 along its axial direction at one end away from the rotating cavity 111. The movable end of the telescopic cylinder has a positioning hole. The moving member 160 passes through the oblong hole 131 and connects to the positioning hole.

[0051] Thus, the telescopic cylinder drives the valve stem 130 to rise or fall away from the rotating chamber 111. At this time, the moving part 160 will move in the waist-shaped hole 131 to pull or push the end of the valve stem 130 connected to the sealing valve core 120 to move downward or upward, thereby driving the sealing valve core 120 to rotate in the rotating chamber 111, thereby realizing the switching between the open state and the closed state.

[0052] In some other embodiments, the drive mechanism 140 may also be a hydraulic cylinder, a drive motor, an electromagnetic drive, an electric push rod, etc. The drive mechanism 140 may also be directly mounted on the valve body 110, or connected to the valve body 110 through other mounting structures.

[0053] Please refer to it again. Figures 4 to 6 In some embodiments, there are multiple water passage holes 113, and the multiple water passage holes 113 are spaced apart along a direction perpendicular to the longitudinal direction of the sealing valve core 120.

[0054] The guiding channel 121 includes an inlet section 1211 and multiple outlet sections 1212, each corresponding to one of the multiple water passages 113. All outlet sections 1212 are connected to the outlet channel 112. After the sealing valve core 120 rotates a preset angle around its central axis in the forward direction, the multiple outlet sections 1212 are aligned with the multiple water passages 113, and the inlet section 1211 is aligned with the connecting hole 114. After the sealing valve core 120 rotates a preset angle in the reverse direction around its central axis, each outlet section 1212 is completely offset from all the water passages 113.

[0055] The spacing directions of the multiple water passages 113 and the multiple water outlet sections 1212 are basically consistent with the rotation direction of the sealing valve core 120. It should be noted that "basically consistent" means that the multiple water passages 113 and the multiple water outlet sections 1212 can be spaced apart along the rotation direction of the sealing valve core 120 (i.e., the circumferential direction of the sealing valve core 120), or they can be spaced apart along a straight line perpendicular to the axial direction of the sealing valve core 120, and this straight line is perpendicular to the liquid flow direction of the water passages 113.

[0056] Multiple water passage holes 113 are provided, and the guiding channel 121 is provided as an inlet section 1211 and multiple outlet sections 1212 connected to the inlet section 1211. When the cylindrical rotary water valve 100 is in the open state, the liquid in the inlet section 1211 enters the outlet channel 112 through multiple channels composed of the outlet section 1212 and the water passage holes 113. This ensures the water flow while reducing the size of each water passage hole 113 and outlet section 1212 in the rotation direction of the sealing valve core 120. This allows the sealing valve core 120 to rotate only a smaller angle, enabling the cylindrical rotary water valve 100 to switch quickly between the open and closed states, thus making the opening and closing speed of the cylindrical rotary water valve 100 faster.

[0057] Please refer to the following: Figure 7In some embodiments, the water outlet channel 112 includes a rectangular through groove 1121 and a circular through hole 1122 communicating with the rectangular through groove 1121. The rectangular through groove 1121 communicates with the water passage hole 113. On a plane perpendicular to the central axis of the circular through hole 1122, the orthographic projection of the rectangular through groove 1121 completely covers the orthographic projections of the circular through hole 1122 and the water passage hole 113.

[0058] The rectangular through-hole 1121 ensures that even if the size of the water passage 113 along the central axis of the sealing valve core 120 is large, all liquid flowing out of the water passage 113 can enter the water outlet channel 112. The circular through-hole 1122 ensures that the liquid pressure flowing out of the water outlet channel 112 meets the requirements of the external liquid circuit. Furthermore, if the size of the water passage 113 along the central axis of the sealing valve core 120 is large, it can shorten its circumferential dimension of the sealing valve core 120 while ensuring sufficient water flow, further reducing the rotation angle of the sealing valve core 120 during the switching process between the open and closed states, and further improving the opening and closing speed.

[0059] Specifically, the liquid flow direction in the inlet section 1211 is perpendicular to the liquid flow direction in the outlet section 1212. The inlet channel 115 is located below the rotating chamber 111. Thus, when the cylindrical rotary water valve 100 is in the open state, the liquid flows from bottom to top in the sealing valve core 120, and then from inside to outside in the horizontal direction. This is beneficial to improving the sealing effect between the sealing valve core 120 and the inner wall of the rotating chamber 111, and further reducing the rotation angle of the sealing valve core 120.

[0060] Please see Figure 4 , Figure 7 and Figure 8 In some embodiments, the valve body 110 includes a valve block 117, an end cap 118, and a valve seat 119. The valve block 117 has a water inlet channel 115, an operating hole 116, and a mounting groove 1171 with one end open. The mounting groove 1171 communicates with the water inlet channel 115 and the operating hole 116, respectively. The valve seat 119 is disposed in the mounting groove 1171 and has a rotating cavity 111, a water passage hole 113, a connecting hole 114, and a through hole 1191 aligned with and communicating with the operating hole 116. The end cap 118 covers the opening of the mounting groove 1171 and is detachably connected to the valve block 117 to press the valve seat 119 into the mounting groove 1171. A water outlet channel 112 is formed at the position of the end cap 118 opposite to the water passage hole 113. One end of the sealing valve core 120 passes through the operating hole 116 and the through hole 1191 in sequence and is connected to the sealing valve core 120.

[0061] During the manufacturing process, the valve body 110 is formed separately into three parts: valve block 117, end cap 118, and valve seat 119. Alternatively, based on the structure of the valve body 110 itself, the valve block 117, end cap 118, and valve seat 119 can be divided into three easily machinable parts, thereby reducing machining difficulty and improving machining accuracy and efficiency. Furthermore, the end cap 118 is detachably connected to the valve block 117, and the end cap 118 presses the valve seat 119 into the mounting groove 1171. This not only makes the disassembly and assembly of components within the valve body 110, such as the sealing valve core 120, more convenient, but also ensures the stable operation of the sealing valve core 120 within the valve body 110.

[0062] Please refer to the following: Figure 9 and Figure 10 Furthermore, in some embodiments, the valve seat 119 includes a first seat body 1192 and a second seat body 1193. A first arcuate groove 11921 is formed recessed on one side surface of the first seat body 1192. A water passage hole 113 penetrating the first seat body 1192 is formed at the bottom of the first arcuate groove 11921. A second arcuate groove 11931 is formed recessed on one side surface of the second seat body 1193. A through hole 1191 penetrating the second seat body 1193 is formed at the bottom of the second arcuate groove 1193. The first seat body 1192 and the second seat body 1193 are spaced apart within the mounting groove 1171 along the direction from the opening of the mounting groove 1171 towards the operating hole 116, and the first arcuate groove 11921 and the second arcuate groove 11931 form a rotating cavity 111. The gap between the first seat body 1192 and the second seat body 1193 located below the rotating cavity 111 serves as a connecting hole 114. The end of the end cap 118 facing the rotating cavity 111 abuts against the first seat 1192.

[0063] Thus, by adjusting the distance between the first seat 1192 and the second seat 1193, the size of the rotating cavity 111 can be adjusted, ensuring the installation accuracy of the sealing valve core 120 during the assembly process, reducing the assembly difficulty, improving the assembly efficiency of the cylindrical rotating water valve 100, and making subsequent maintenance work more convenient.

[0064] Specifically, the first seat 1192 and the second seat 1193 are parallel and spaced apart along the direction from the opening of the mounting groove 1171 toward the operating hole 116. Of course, in other embodiments, the first seat 1192 and the second seat 1193 may not be parallel, as long as they are spaced apart.

[0065] Please refer to it again. Figure 4 and Figure 7 Furthermore, the end cap 118 is provided with a supporting part 1181 along the circumference of the water outlet channel 112 on the side facing the rotating cavity 111. The supporting part 1181 extends into the mounting groove 1171 and supports the end of the first seat 1192 opposite to the second seat 1193.

[0066] Specifically, when the water outlet channel 112 includes a rectangular through groove 1121 and a circular through hole 1122, the supporting part 1181 is arranged circumferentially along the rectangular through groove 1121. Of course, in actual production, the end cap 118 can be a one-piece molded structure, or it can be formed by welding or other means by connecting a plate with a circular through hole 1122 and the supporting part 1181 that can surround and form the rectangular through groove 1121.

[0067] The support part 1181 ensures that while the end cap 118 presses the sealing valve core 120 into the rotating cavity 111 through the first seat 1192, the sealing effect between it and the valve body 110 is good, reducing the probability of leakage.

[0068] Please refer to it again. Figures 1 to 3 In some embodiments, the water inlet channel 115 extends axially along the sealing valve core 120. There are multiple rotating chambers 111. These multiple rotating chambers 111 are spaced apart along the extending direction of the water inlet channel 115. The number of water outlet channels 112, water passage holes 113, connecting holes 114, and operating holes 116 are all multiple, each corresponding to one of the multiple rotating chambers 111.

[0069] There are multiple sealing valve cores 120, valve stems 130, and drive mechanisms 140. Multiple sealing valve cores 120 are respectively disposed in multiple rotating chambers 111. Multiple valve stems 130 are respectively disposed in corresponding operating holes 116. One end of each valve stem 130 is connected to the corresponding sealing valve core 120, and the other end is connected to the corresponding drive mechanism 140 for transmission.

[0070] Thus, the cylindrical rotary water valve 100 can realize single-inlet and multi-outlet liquid branch control. It can also connect different numbers and positions of water outlet channels 112 with external liquid circuits by plugging the outlet channels 112 according to actual needs, thereby improving the applicability of the cylindrical rotary water valve 100.

[0071] Specifically, when the cylindrical rotary water valve 100 also includes a base 150, multiple drive mechanisms 140 and valve body 110 are all installed on the base 150, which facilitates the transportation and on-site installation and use of the cylindrical rotary water valve 100.

[0072] Specifically, when the valve body 110 includes a valve block 117, an end cover 118, and a valve seat 119, the number of end covers 118 and the number of valve seats 119 are both multiple, each corresponding to a multiple rotating chamber 111. The multiple end covers 118 reduce material costs and also reduce the difficulty of installing the end covers 118 on the valve block 117, thereby improving installation accuracy.

[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
