[0104] In order to enable those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0105] In the embodiments of the present application, digital features such as "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.
[0106] Please refer to Figures 1 - 4 , Figure 1 which is a schematic structural diagram of an embodiment of the valve device of the present application; Figure 2 is Figure 1 the exploded view of the valve device in Figure 3 is Figure 1 a schematic diagram from another perspective; Figure 4 is Figure 3 the partial cross - sectional view of the valve device in
[0107] The valve device in this embodiment can be a water valve, that is, it controls the flow of water and is used in the thermal management component of a vehicle. Of course, the valve device can also be other types of valves for controlling other types of fluids and can also be applied to application scenarios other than vehicles. The valve device includes a valve body 100, a driving component 11, and a spool 03. The valve body 100 has a valve cavity, the spool 03 is located in the valve cavity, the driving component 11 is used to drive the spool 03 to rotate around the axis X, and the rotation of the spool 03 can adjust the opening and closing as well as the opening degree of the valve device.
[0108] As Figure 2As shown, the valve body 100 in this embodiment is of a split structure, including a first valve body part 01 and a second valve body part 06. The first valve body part 01 and the second valve body part 06 are fixedly connected. The first valve body part 01 has a first chamber 014, and the second valve body part 06 has a second chamber 0611. The valve chamber includes the first chamber 014 and the second chamber 0611. The first valve body part 01 and the second valve body part 06 are butt-connected, and the first chamber 014 and the second chamber 0611 are butt-connected to form the valve chamber. In this embodiment, both the first valve body part 01 and the second valve body part 06 include valve body parts that are generally hemispherical. The first chamber 014 and the second chamber 0611 are correspondingly hemispherical chambers. In this way, after the first valve body part 01 and the second valve body part 06 are butt-connected, the first chamber 014 and the second chamber 0611 are butt-connected to form a spherical valve chamber. In this embodiment, the valve body 100 of the valve device is split into the first valve body part 01 and the second valve body part 06. In this way, hemispherical chambers can be formed on the split valve body parts, and then butt-connected to form a complete spherical valve chamber, so that the manufacture of the valve body 100 is simpler.
[0109] Figure 4 In the figure, when the first valve body part 01 and the second valve body part 06 are split, the valve body 100 is divided into two parts by the plane where the axis of rotation of the valve core 03 is located, that is, the axis of rotation of the valve core 03 is located on the plane where the first valve body part 01 and the second valve body part 06 are butted, and the valve body 100 is divided into two parts by the plane where the axis X is located.
[0110] Next, the specific structures of the first valve body part 01 and the second valve body part 06, as well as their specific connection methods, will be described in detail.
[0111] As Figures 5 - 10 shown, Figure 5 is Figure 1 a schematic structural view of the first valve body part 01 in the figure; Figure 6 is Figure 5 the front view of ; Figure 7 is Figure 5 the axial sectional view of the first valve body part 01 in the figure, and the axial direction is the direction of the axis of rotation of the valve core 03; Figure 8 is Figure 1 a schematic structural view of the second valve body part 06 in the figure; Figure 9 is Figure 8 the bottom view of ; Figure 10 is Figure 8 the sectional view in the A-A direction in the figure.
[0112] The first valve body part 01 has a first valve body end face 019 facing the second valve body part 06. As described above, the first chamber 014 of the first valve body part 01 is a hemispherical chamber, and the first valve body end face 019 corresponds to the end face on the side of the opening of the hemispherical chamber. As Figure 6As shown. Correspondingly, the second valve body part 06 has a second valve body end face 0632 facing the second valve body part 06. When the first valve body part 01 and the second valve body part 06 are butted, the first valve body end face 019 and the second valve body end face 0632 are butted, that is, the first valve body end face 019 and the second valve body end face 0632 are fitted together. The butted surface of the two is either the first valve body end face 019 or the second valve body end face 0632.
[0113] After the first valve body part 01 and the second valve body part 06 are butted, the sealing performance of the butted position needs to be ensured. At this time, an annular groove 013a can be provided on at least one of the first valve body end face 019 and the second valve body end face 0632. The valve device further includes an annular first sealing part 02 (shown in Figure 2 ), and a part of the first sealing part 02 is embedded in the annular groove 013a. Figure 5 In [a certain situation], only the annular groove 013a is provided on the first valve body end face 019 of the first valve body part 01, which matches the hemispherical feature of the first valve body part 01. The annular groove 013a can be a circular groove, and the first sealing part 02 can be a circular sealing ring. In this way, after the first valve body part 01 and the second valve body part 06 are butted, the sealing ring is pressed between the first valve body part 01 and the second valve body part 06, and the first valve body part 01 and the second valve body part 06 can be reliably sealed. It can be seen that it is also possible to provide an annular groove on the second valve body end face 0632 of the second valve body part 06, or annular grooves are provided on both valve body end faces, and a part of the first sealing part 02 is located in the two annular grooves respectively. It should be understood that the first sealing part must be squeezed to achieve the sealing purpose.
[0114] Specifically, in the first valve body end face 019 and the second valve body end face 0632 of this embodiment, one is provided with a concave part, and the other is provided with a convex part that can be inserted into the concave part. Please continue to refer to Figure 5 、 8 , the first valve body part 01 is provided with concave parts 016, 017, and the second valve body part 06 is provided with convex parts 0616, 0617. With such a setting, when the first valve body part 01 and the second valve body part 06 are butted, the convex parts 0616, 0617 can be inserted into the concave parts 016, 017 to limit the relative position of the first valve body part 01 and the second valve body part 06 in the circumferential direction. In this way, the connection is more reliable, and it is convenient to determine the installation position, which is beneficial to the assembly.
[0115] In this embodiment, the first valve body portion 01 includes a hemispherical portion 011. The end face on the opening side of the hemispherical portion 011 is the aforementioned first valve body end face 019. Specifically, an annular flange 0111 is provided at the opening end of the hemispherical portion 011, and the first valve body end face 019 includes the end face of the annular flange 0111. This can provide a larger size for docking with the second valve body end face 0632 and has sufficient area to form an annular groove 013a. Correspondingly, the second valve body portion 06 includes a hemispherical portion 061. The end face on the opening side of the hemispherical portion 061 is the aforementioned second valve body end face 0632. Specifically, an annular flange 0631 is provided at the opening end of the hemispherical portion 061, and the second valve body end face 0632 includes the end face of the annular flange 0631.
[0116] Continue to combine with Figure 11 understand, Figure 11 is Figure 2 the structural schematic diagram of the first sealing portion in
[0117] In this embodiment, for the first valve body portion 01 or the second valve body portion 06 provided with the annular groove 03, when the convex portions 0616, 0617 or the concave portions 016, 017 are provided, at least part of the convex portions 0616, 0617 or the concave portions 016, 017 can be located in the annular groove 013a. In this way, the convex portions 0616, 0617 and the concave portions 016, 017 can have a larger area to ensure reliable cooperation. At this time, the first sealing portion 02 can be partially recessed to form a sealing recessed portion 021, and the sealing recessed portion 021 can be adapted to the convex portions 0616, 0617 and the concave portions 016, 017, that is, the sealing recessed portion 021 is located in the concave portions 016, 017, and the convex portions 0616, 0617 can abut against the sealing recessed portion 021.
[0118] Please combine with Figure 5 , 8 and Figure 1 understand, at one end of the first valve body portion 01 in this embodiment facing the second valve body portion 06, there is a first ear portion 01111 extending in a direction away from the first chamber 014. Specifically, the first ear portion 01111 can extend radially along the first valve body end face 019, and the first ear portion 01111 has a first connection hole 018; at one end of the second valve body portion 06 facing the first valve body portion 01, there is a second ear portion 06311 extending in a direction away from the second chamber 0611. Similarly, the second ear portion 06311 can extend radially along the second valve body end face 0632, and the second ear portion 06311 has a second connection hole 0618.
[0119] The valve device further includes a fastener 05, such as a fastening bolt, a fastening screw, etc. The fastener 05 is inserted into the first connection hole 018 and the second connection hole 0618 to connect and fix the first valve body part 01 and the second valve body part 06. Each valve body part may be provided with a plurality of ears evenly distributed in the circumferential direction. In this embodiment, specifically, four first ears 01111 and second ears 06311 are provided, and they are arranged in one-to-one correspondence, so that the first valve body part 01 and the second valve body part 06 can be fixed more reliably. Of course, it is not necessary to provide ears for connecting and fixing the first valve body part 01 and the second valve body part 06. Here, providing ears facilitates the arrangement of connection holes, does not occupy the space for arranging the annular groove, and is conducive to ensuring the sealing performance.
[0120] Look at Figure 12 、 13 , Figure 12 is Figure 8 a schematic structural view of the second valve body part 06 from another perspective in Figure 13 is Figure 12 an axial sectional view of the second valve body part 06 in
[0121] The valve device in this embodiment includes an installation part 062, which is integrally provided on the first valve body part 01 or the second valve body part 06, that is, the installation part 062 is a part of the first valve body part 01 or a part of the second valve body part 06. For example, it can be integrally formed by injection molding. In this embodiment, the installation part is integrally formed on the second valve body part 06 and is integrally formed with the hemispherical part 062. The driving component 11 of the above valve device is installed on the installation part.
[0122] As Figure 8 shown, the installation part 062 is located on one side in the radial direction of the hemispherical part 061 of the second valve body part 06, specifically on one side of the convex part 0616. As Figure 12 shown, the main body of the installation part 062 is a plate-shaped main body 062a, and the plate-shaped main body 062a is integrally connected to the hemispherical part 061 of the first valve body part 01. The plate-shaped main body 062a is provided with a plurality of reinforcing ribs 0624 on the side away from the second chamber 0611 to improve the strength. The driving component 11 is supported on the side of the plate-shaped main body 062a away from the second chamber 0611. A bracket 062b protruding from the plate-shaped main body 062a is provided on one side of the plate-shaped main body 062a. The bracket 062b is provided with an installation hole 0623, which can be used to connect the entire valve device to the required equipment. In addition, a fixing hole 0622 is also provided on the bracket 062a, and the plate-shaped main body 062a is provided with a convex column, and the convex column is also provided with a fixing hole 0622. The fixing hole 0622 is used to fix the driving component 11 and the installation part 062. The fixing hole 0622 and the fixing hole 112 (shown in Figure 17 ) on the driving component 11 are arranged in one-to-one correspondence and can be inserted with a fastener 12 for fixing as Figure 2 shown.
[0123] Look again Figure 12 , the installation part 062 has a first jack 0621, and the first jack 0621 communicates with the second chamber 0611. The driving component 11 includes a valve core shaft 07 (shown in Figure 2 ), the valve core shaft 07 passes through the first jack 0621 to be in transmission connection with the valve core 03. The driving component 11 may include a motor, and the motor can directly drive or indirectly drive the valve core shaft 07 to rotate through a transmission component (such as a gear set), and then the valve core shaft 07 drives the valve core 03 to rotate.
[0124] It is worth mentioning that for the embodiment provided with the convex portion 0616, the first jack 0621 may penetrate the convex portion 0616. Since the interface surface between the first valve body portion 01 and the second valve body portion 06 is the plane where the axis is located, if the first jack 0621 is completely arranged in the first valve body portion 01 or completely arranged in the portion of the second valve body portion 06 outside the convex portions 0616 and 0617, the axis of the first jack 0621 will deviate. Here, the first jack 0621 is arranged on the convex portion 0616, so that it can be arranged on only one valve body portion, which can better ensure that the axis of the first jack 0621 is coaxial with the axis of the valve core shaft 07, without being separately arranged on two valve body portions and pieced together, and the cooperation with the valve core shaft 07 is more reliable. Look again Figure 13 , the plate-shaped main body 062a of the installation part in this embodiment is substantially perpendicular to the axis, which is convenient for the valve core shaft 07 of the installed driving component 11 to be inserted into the first jack 0621.
[0125] Continue to refer to Figure 13 , the first jack 0621 in this embodiment is a stepped hole, that is, the first jack 0621 includes at least two hole segments with different diameters distributed along the axis. The hole segment with the smallest diameter is the first hole segment 0613, and the valve core shaft 07 is in clearance fit with the first hole segment 0613 to ensure that the valve core shaft 07 can rotate in the first jack 0621. The first hole segment 0613 may be at least partially formed in the convex portion 0616.
[0126] Figure 13 In, the first jack 0621 further includes a second hole segment 0614, a third hole segment 0615, and a fourth hole segment 06212. The first hole segment 0613, the second hole segment 0614, the third hole segment 0615, and the fourth hole segment 06212 are connected in sequence and the diameters gradually increase. The corresponding hole wall of the first jack 0621 is a stepped surface between adjacent two hole segments, which are the first stepped surface 06141, the second stepped surface 06151, and the third stepped surface 06211 respectively.
[0127] It can be understood in combination with Figure 14 that Figure 14 is Figure 2 an enlarged view of the fitting position of the valve core shaft 07 and the first jack in.
[0128] The valve device further includes an annular sealing member which is sleeved on the valve core shaft 07 and supported on a stepped surface. In this embodiment, three stepped surfaces are provided. Correspondingly, the sealing member is an assembly, which respectively includes a wear-resistant ring 08, a second sealing portion 09 and a sealing portion end cover 10. Among them, the wear-resistant ring 08 is arranged in the second hole section 0614 and supported on the first stepped surface 06141, the second sealing portion 09 is arranged in the third hole section 0615 and supported on the second stepped surface 06151, and the sealing portion end cover 10 is arranged in the fourth hole section 06212 and supported on the third stepped surface 06211. The output end 111 of the driving member 11 is also provided with a sealing member, which can axially abut against the sealing portion end cover 10.

[0130] The valve core shaft 07 includes a first shaft section 071, a second shaft section 072 and a third shaft section 073 which are sequentially distributed along the axial direction. One end of the first shaft section 071 is used to cooperate with the output end 111 of the transmission assembly of the driving member 11. The first shaft section 071 may have a first flat surface 0711, so as to be in transmission cooperation with the transmission hole having a flat hole wall of the output end 111. The transmission hole is, for example, a square hole or a D-shaped hole, etc. A sealing portion is provided between the cylindrical portion of the first shaft section 071 without a flat surface and the second hole section 0614 and the third hole section 0615. The second shaft section 072 includes a second flat surface 0721. The cylindrical portion without a flat surface is located in the first hole section 0613 and is in clearance fit with the hole wall of the first hole section 0613. The second flat surface 0721 of the second shaft section 072 is inserted into the valve core 03 to be in transmission cooperation with the valve core 03. In this embodiment, a second jack 0612 is further provided on the wall of the second chamber 0611 of the second valve body portion 06. The third shaft section 073 is inserted into the second jack 0612 of the second valve body portion 06.
[0131] In this embodiment, the diameters of the first shaft section 071, the second shaft section 072 and the third shaft section 073 decrease in sequence to ensure sealing fit while realizing transmission connection. There is a shaft stepped surface 074 between the second shaft section 072 and the first shaft section 071.
[0132] It can be further referred to Figures 18 - 26 for understanding that Figure 18 For Figure 14 the structural schematic diagram of the wear-resistant ring 08 in Figure 19 For Figure 18Front view of the middle wear-resistant ring 08; Figure 20 is Figure 19 Top view of the middle wear-resistant ring 08;

[0134] The wear-resistant ring 08 in this embodiment has a first inner peripheral wall 081, a first outer peripheral wall 082, and a first end face 084 and a second end face 083 distributed axially. Among them, the first outer peripheral wall 082 is in sealing fit with the hole wall 06142 of the second hole section 06141, and a clearance is provided between the first inner peripheral wall 082 and the cylindrical part of the second shaft section 072 where the first flat surface 0721 is not provided. The first end face 084 is in contact with the first step surface 06141, and the second end face 083 is in contact with the shaft step surface 074.
[0135] The second sealing part 09 can be a sealing ring, which has a second inner peripheral wall 091 and a second outer peripheral wall 092. The second inner peripheral wall 091 is in sealing fit with the cylindrical section of the first shaft section 071 where the first flat surface 0711 is not provided; the second outer peripheral wall 092 is in sealing fit with the hole wall 06152 of the third hole section 0615.
[0136] The sealing part end cover 10 has a third inner peripheral wall 101 and a third outer peripheral wall 102. The third inner peripheral wall 101 is arranged with a clearance from the cylindrical section of the first shaft section 071 where the first flat surface 0711 is not provided; the third outer peripheral wall 102 is arranged in cooperation with the hole wall of the fourth hole section 06212; the sealing part end cover 10 has a relatively arranged third end face 103 and a fourth end face 105.

The sealing part end cover 10 can be pressed between the sealing component 113 of the driving component 11 and the second sealing part 09 to better compress the second sealing part 09 and meet the sealing effect.
[0138] Please refer to Figures 27 - 32 shown in Figure 27 is Figure 2 the three-dimensional structure schematic diagram of the valve core 03 in Figure 28 is Figure 27 the front view of Figure 29 is Figure 28 the sectional view taken along the line B-B of Figure 30 is Figure 29 the sectional view taken along the line C-C of Figure 31 is Figure 28 the right view of Figure 32 is Figure 28 the top view of
[0139] The valve core 03 in this embodiment is a butterfly valve core 03, and the valve core 03 is provided with a through hole 031. After the valve core shaft 07 passes through the first plug hole 0621 of the second valve body 06, it can pass through the through hole 031 of the valve core 03 to be connected with the valve core 03 in a transmission manner. For this purpose, the through hole 031 can be set as a D-shaped through hole, and the second straight surface 0721 of the second shaft section 072 of the valve core shaft 07 cooperates with the through hole 031, thereby driving the valve core 03 to rotate. The valve core 03 has a valve core outer wall 034, and the valve core outer wall 034 is a spherical surface that can be adapted to the spherical inner wall surface corresponding to the valve cavity of the valve body. The valve core outer wall 034 is a partial spherical surface, and the center of the through hole 031 passes through the spherical center corresponding to the valve core outer wall 034. Of course, the valve core outer wall 034 is not limited to a spherical surface, as long as the valve core 03 is rotating, the third sealing part 04 described below and the inner wall surface corresponding to the valve cavity of the valve body can always abut and fit.
[0140] The outer diameter of the valve core outer wall 034 is matched with the diameter of the spherical valve cavity, and the valve core outer wall 034 can slide along the inner wall of the valve cavity. The valve core outer wall 034 of the valve core 03 can be provided with an annular groove 033, and the valve device also includes a third sealing part 04, the groove 033 is matched with the third sealing part 04, and the third sealing part 04 can be a sealing ring. The plane formed by the side wall of the groove 033 is parallel to the central axis of the through hole 031 and has a certain distance D from the central axis, such as Figure 29 As shown, since there is a distance, the distance D must be a number greater than 0. The third sealing portion 04 is pressed against the bottom wall of the groove 033 and the inner wall surface corresponding to the valve cavity of the valve body to achieve better sealing performance.
[0141] The valve core 03 in this embodiment can be combined with Figure 4 It is understood that the central axis of the through hole 031 is also the central axis of the valve core shaft 07. When the valve core shaft 07 rotates, it drives the valve core 03 to rotate in the valve cavity. The valve body 100 in this embodiment includes a first valve body part 01 and a second valve body part 06 that are connected to each other. The central axis is located on the connecting surface. Here, the groove 033 is spaced from the central axis. The third sealing part 04 set in the groove 033 can be spaced from the joint of the two valve body parts to avoid the joint position affecting the third sealing part 04. The third sealing part 04 always slides on the inner wall surface of the valve cavity spaced a distance around the central axis to ensure the sealing performance of the third sealing part 04. The side wall of the groove 033 and the axis of the through hole 031 are arranged parallel to each other, so that when the third sealing part 04 contacts the inner wall surface corresponding to the valve cavity during the rotation process, the force is more uniform.
[0142] In addition, on the other side of the central axis of the through hole 031 opposite to the groove 033, the valve core 03 is provided with a V-shaped surface 032, that is, Figure 27 From the perspective, when projected in a direction parallel to the central axis, the spherical outer wall 034 has a generally V-shaped profile, such asFigure 28 As shown, the ridge line of the V-shaped surface 032 is arranged parallel to the central axis of the through hole 031. The ridge line of the V-shaped surface 032 is a line passing through the vertex 0321 of the V-shaped surface 032 and parallel to the through hole 031. The outer wall 034 of the valve core has two oppositely arranged V-shaped surfaces 032. Connecting the vertices 0321 of the two V-shaped surfaces 032 can determine the ridge line. For example, Figure 32 As shown. With this setting, on the premise of providing the through hole 031, the area of the outer wall 034 of the valve core 03 of the valve core can be minimized to reduce the friction with the inner wall surface of the valve cavity during rotation and improve the smoothness of rotation. The arc transition can minimize the influence on the fluid flow.
[0143] For example, Figure 27 、 31 As shown in 32 and 33, the valve core 03 in this embodiment includes a butterfly-shaped valve plate 036. The valve plate 036 can play a role in cutting off the fluid flow. The above-mentioned outer wall 034 of the valve core surrounds the valve plate 036. A reinforcing rib 035 can be provided on one side of the valve plate 036 to improve the strength of the valve core 03. A valve core column 037 is also provided on one side of the valve plate 036. The through hole 031 can be arranged to penetrate the valve core column 037. Of course, the part between the valve plate 36 and the outer wall 034 of the valve core can also be solid, and the through hole 031 passes through the solid part. However, the setting method in this embodiment is used to reduce the material consumption and reduce the weight of the valve core 03.
[0144] In addition, as Figure 6 、 7 As shown in 10, the first valve body part 01 in this embodiment has a first connection part 012. The first connection part 012 has a first channel 015. The second valve body part 06 has a second connection part 0619. The second connection part 0619 has a second channel 0620. The first channel 015 communicates with the first chamber 014. The second channel 0620 communicates with the second chamber 0611. The driving component 11 drives the valve core 03 to rotate to adjust the closing, communication of the first channel 015 and the second channel 0620, and the opening degree when communicating.
[0145] For example, Figures 34 - 37 Understood, Figure 34 is Figure 1 a schematic diagram of the valve device in the closed state in; Figure 35 is Figure 1 a schematic diagram of the valve device in the fully open valve state in; Figure 36 is Figure 1 a schematic diagram of the valve device in the position state between closed and open valve in.
[0146] The driving component 11 drives the valve core shaft 07 to rotate. The valve core shaft 07 drives the valve core 03 to rotate together. When the valve core 03 is in the closed valve state, the valve device is in the closed state, as Figure 34As shown, the first channel 015 and the second channel 0620 are not connected; when the valve core 03 is in the fully open valve state, the valve device is in the fully open state, as Figure 35 shown, the first channel 015 and the second channel 0620 are connected; when the valve core 03 is in the middle state between the closed valve state and the fully open state, the valve core 03 is in different positions, and the flow rate of the valve device is also different. The flow rate of the valve device can be adjusted by adjusting the position of the valve core 03, as Figure 36 shown.
[0147] Please continue to refer to Figures 37 - 39 , Figure 37 which is a schematic structural diagram of another embodiment of the valve device of the present application; Figure 38 is Figure 37 the exploded view of the valve device in Figure 39 is Figure 37 the partial cross-sectional view of the valve device in
[0148] The setting principle of the valve device in this embodiment is similar to that of the valve device in the above embodiment. The valve body 200 is also separately provided with a first valve body part 001 and a second valve body part 002, but Figures 37 - 39 the valve core 003 structure of the valve device in
[0149] Look at Figures 40 - 42 again, Figure 40 which is Figure 38 the three-dimensional structural schematic diagram of the valve core 003 of the valve device in Figure 41 is Figure 40 the front view of Figure 42 is Figure 41 the D-D cross-sectional view of
[0150] The valve core 003 in this embodiment has a valve core outer wall 00308. Compared with the embodiment of the above butterfly valve core 003, Figure 40 the valve core outer wall 00308 in
[0151] In addition, both ends of the valve core 003 along its axial direction are provided with a first boss 00301 and a second boss 00302. Both bosses are cylindrical structures. The first boss 00301 and the second boss 00302 are coaxially arranged, and the axis passes through the center of the spherical surface of the outer wall 00308 of the valve core. The axis is also the axis of rotation of the valve core shaft 009. A first interface 00303 and a second interface 00304 are provided on the outer wall 00308 of the valve core. The planes where the first interface 00303 and the second interface 00304 are located are both parallel to the axes of the first boss 00301 and the second boss 00302. Among them, the top end of the first boss 00301 is provided with a flat surface 00306, and a groove 00307 is provided on the flat surface 00306. The groove 00307 can be a rectangular groove.
[0152] As Figures 43 - 45 shown, Figure 43 Figure Figure 38 is a schematic structural view of the valve core shaft 009 in Figure 44 Figure Figure 43 ; it is the front view of Figure 45 Figure Figure 39 is an enlarged view of the mating position of the valve core shaft 009 and the mounting portion of the first valve body part 001 in
[0153] The valve core shaft 009 is provided with a second shaft section 00902, a first shaft section 00901 and a third shaft section 00903 that are sequentially connected along the axial direction. Among them, the first shaft section 00901 is a cylindrical shaft section, and both the second shaft section 00902 and the third shaft section 00902 are flat shaft sections with flat surfaces. The third shaft section 00903 can be in transmission cooperation with the output end of the driving component 013; the second shaft section 00902 can be cooperatively arranged with the groove 00307 on the valve core 003, and the first shaft section 00901 and the first valve body part 001 are hermetically arranged to realize the transmission connection of the driving component 013, the valve core shaft 009 and the valve core 003.
[0154] Please look at Figures 46 - 50 again, Figure 46 Figure Figure 38 is a schematic three-dimensional structure view of the first valve body part 001 in Figure 47 Figure Figure 46 is a schematic three-dimensional structure view of the first valve body part 001 from a second perspective in Figure 48 Figure Figure 46 is a schematic three-dimensional structure view of the first valve body part 001 from a third perspective in Figure 49 Figure Figure 48 is a sectional view taken along the E-E direction of Figure 50 Figure Figure 46 is a partial sectional view of the first valve body part 001 in
[0155] Among them, the first valve body part 001 includes a hemispherical part 00101. A first connecting pipe 00102 and a second connecting pipe 00103 are arranged on the spherical part 00101. The first valve body part 001 has a generally hemispherical inner cavity, that is, a first chamber 00114; a first channel 001021 is arranged inside the first connecting pipe 00102, and a second channel 001031 is arranged inside the second connecting pipe 00103; the first channel 001021 and the second channel 001031 communicate with the hemispherical first chamber 00114. At the intersection of the first channel 001021 and the hemispherical first chamber 00114 on the inner wall surface of the first valve body part 001, a first groove structure 00116 is arranged, and at the intersection of the second channel 001031 and the hemispherical second chamber 00209, a second groove structure 00117 is arranged. Both the first groove structure 00116 and the second groove structure 00117 are annular grooves, and both can be used to place an internal leakage valve seat 005 and an internal leakage seal 006. When the valve core 003 rotates in the valve cavity, the internal leakage valve seat 005, the internal leakage seal 006 and the outer wall 00308 of the valve core 003 of the valve core cooperate to achieve sealing, preventing fluid from leaking from the outer wall 00308 of the valve core and the inner wall surfaces of the first valve body part 001 and the second valve body part 002.
[0156] In addition, the end faces of the first valve body part 001 and the second valve body part 002 in this embodiment are respectively a first valve body end face 00106 and a second valve body end face 00206. Figures 1 - 4 The surfaces where the first valve body end face 019 and the second valve body end face 0632 mentioned in the embodiment are butted are also the planes where the axes are located, that is, the first valve body end face 019 and the second valve body end face 0632 are the central bisecting planes of the sphere, but Figure 46 in the embodiment of, the first valve body end face 00106 of the first valve body part 001 is not the central bisecting plane of the sphere. The first valve body part 001 further includes a first cylindrical wall 00105. The first cylindrical wall 00105 extends along the end face of the hemispherical part 00101 in a direction away from the first chamber 00114. The inner diameter of the first cylindrical wall 00105 is larger than the inner diameter of the hemispherical part 00101. Then an annular valve body step surface 00104 is formed between the first cylindrical wall 00105 and the end face of the hemispherical part 00101. The valve body step surface 00104 is the central bisecting plane. An annular flange is arranged at the end of the cylindrical wall 00105, and the end face of the annular flange is the first valve body end face 00106. An annular groove 00109 is arranged on the first valve body end face 00106 (a part of the first sealing part 004 is embedded in the annular groove 00109). A first connection hole 00115 is also arranged on the first valve body end face 00106, which is used to correspond to the second connection hole 00213 on the second valve body part 002 one by one, and through Figure 38The fastener 015' shown is fixed. The connection and fixation method of the first valve body part 001 and the second valve body part 002 is the same as that of the above embodiment, that is, an annular flange, connecting ears, an annular groove 00109, etc. are provided, and it is sealed by the first sealing part 004, which will not be elaborated here. It can be seen that without setting the annular flange, it is also possible to directly set the annular groove 00109 on the end face of the first cylindrical wall 00105.
[0157] As Figure 46 , 47 shown, the valve body step surface 00104 is recessed in two positions along its radial direction away from the cylindrical wall 00105 to form a first semi-circular groove 00107 and a second semi-circular groove 00108. The first semi-circular groove 00107 and the second semi-circular groove 00108 are concentrically arranged, and the axes of the two semi-circular grooves are located on the central bisecting plane 00104. And the axes of the first semi-circular groove 00107 and the second semi-circular groove 00108 are perpendicular to the plane where the axes of the first nozzle 00102 and the second nozzle 00103 are located, that is, the first nozzle 00102 and the second nozzle 00103 are perpendicular to the axis of rotation of the valve core 03. This facilitates the valve core 03 to control the valve core 03 to block or move away from the ports of the two nozzles when rotating.
[0158] It can be further combined with Figures 51 - 53 , Figure 51 which is Figure 38 the three-dimensional structure schematic diagram of the second valve body part 002 in Figure 52 which is Figure 51 the front view of Figure 53 which is Figure 52 the sectional view taken along the F-F direction of
[0159] The second valve body part 002 includes a hemispherical part 00201. A third nozzle 00202 and a fourth nozzle 00203 are arranged on the outer wall of the hemispherical part 00201. A hemispherical second chamber 00209 is arranged inside the hemispherical part 00201; a third channel 002021 is arranged inside the third nozzle 00202, and a fourth channel 002031 is arranged inside the fourth nozzle 00203; both the third channel 002021 and the fourth channel 002031 communicate with the second chamber 00209. On the inner wall surface of the first valve body part 001, a third groove structure 00211 is arranged at the intersection of the third channel 002021 and the second chamber 00209, and a fourth groove structure 00212 is arranged at the intersection of the fourth channel 002031 and the second chamber 00209. The third groove structure 00211 and the fourth groove structure 00212 are used to place the internal leakage valve seat 005 and the internal leakage seal 006, which have the same function as the first groove structure 00116 and the second groove structure 00117 arranged on the first valve body part 001.
[0160] In addition, the second valve body part 002 further includes a second cylindrical wall 00215. The second cylindrical wall 00215 extends from the inner side of the end face of the hemispherical part 00201 in a direction away from the second chamber 00209. The end face of the second cylindrical wall 00215 is the central bisecting plane of the hemisphere and can be butted and fitted with the above-mentioned valve body step surface 00104. The width of the valve body step surface 00104 in its radial direction can be equal to the width of the cylindrical wall end face 00204 of the second cylindrical wall 00215, that is, their inner diameters and outer diameters are equal. An annular flange can also be provided at the end of the hemispherical part 00201 of the second valve body part 002 and used to provide connection ears for providing the second connection hole 00213. At this time, the end face of the annular flange is the second valve body end face 00206 and is used to butt against the first valve body end face 00106.
[0161] Corresponding to the first valve body part 001, third semi-circular grooves 00207 and fourth semi-circular grooves 00208 are provided at two places along the radial direction of the cylindrical wall end face 00204 of the second cylindrical wall 00205 of the second valve body part 002. Both semi-circular grooves are recessed from the end face of the second cylindrical wall 00205 in a direction close to the second chamber 0020. The third semi-circular groove 00207 and the fourth semi-circular groove 00208 are concentrically arranged, and the axes of the third semi-circular groove 00207 and the fourth semi-circular groove 00208 are on the cylindrical wall end face 00204.

[0171] In the above-mentioned embodiments, the valve cavities of the valve bodies 100 and 200 are spherical cavities or approximately spherical cavities. The inner wall surface of the valve cavity has a relatively complete spherical surface, but the inner wall surface of the valve cavity can also be partially spherical.

[0173] For the embodiment of the butterfly valve core 003, the valve core 003 only needs to be in sealing contact with the inner wall surface of the valve cavity in the closed valve state. In the open valve or flow regulation state, the valve core 003 does not need to be in sealing contact with the inner wall surface of the valve cavity. Therefore, the inner wall surface of the valve cavity can be partitioned only. The inner wall surface of the valve cavity includes a mating surface 0B that is in sealing contact with the valve core 03 in the closed valve state. A reference spherical surface S is defined. A part of the mating surface 0B coincides with the reference spherical surface S, that is, the mating surface 0B is a partial spherical surface, so that it can be adapted to the outer wall 034 of the valve core 03 that is a partial spherical surface, so as to achieve sealing contact in the closed valve state. At least part of the surface of the inner wall surface of the valve cavity other than the mating surface 0B can be set as a concave surface 0A. The concave surface 0A is formed by being recessed relative to the reference spherical surface S. In this way, in the closed valve state, the mating surface OB and the valve core 003 can be in sealing contact. In other states, there is a distance d between the outer wall 034 of the valve core 003 and the concave surface 0A, so that the wear of the valve core 003 can be reduced and the service life can be improved.
