Description

Technical Field

[0001] The present invention relates to a technique for a mounting member for attaching a valve drive mechanism to a valve opening / closing mechanism.

Background Art

[0002] Conventionally, techniques for mounting members for attaching a valve drive mechanism to a valve opening / closing mechanism are known in the art. For example, as described in Patent Document 1.

[0003] Patent Document 1 describes a valve mechanism for opening and closing a valve port, and a drive mechanism for driving the valve mechanism. The drive mechanism is attached to the yoke of the valve mechanism via a mount base.

[0004] Here, in the technique described in Patent Document 1, the lower portion of the mount base is arranged to overlap with the yoke when viewed from the side. In this state, bolts or the like (first fasteners) are inserted through the mount base and the yoke from the horizontal direction, whereby the mount base is fixed to the yoke.

[0005] However, in general, valves such as that described in Patent Document 1 are often installed in a state where their sides are surrounded by a basin, and the lateral work space is limited. For this reason, in the method of fixing with fasteners from the horizontal direction as described in Patent Document 1, it was difficult to fix the mount base to the yoke.

[0019] In the following description, the directions indicated by arrow U, arrow D, arrow F, arrow B, arrow L and arrow R in the drawings are defined as the upward direction, downward direction, forward direction, rearward direction, leftward direction and rightward direction respectively.

[0020] First, the overall configuration of the valve device 1 will be described with reference to Figure 1 and Figure 2.

[0021] The valve device 1 is capable of controlling water supply and drainage by opening and closing a water channel. In the present embodiment, as an example, the valve device 1 for opening and closing the water supply pipe P that supplies water to a paddy field is described, but the application of the valve device 1 is not limited to this, and it can be used for water supply and drainage to various fields and the like. The valve device 1 mainly includes a valve opening and closing mechanism 10, a valve drive mechanism 30, and a mounting member 100.

[0022] The valve opening / closing mechanism 10 switches whether or not water can be supplied from the water supply pipe P by opening and closing the water supply pipe P. The valve opening / closing mechanism 10 mainly comprises a valve seat 11, a yoke 20, a valve stem 12, a valve body 13, and a handle 14.

[0023] The valve seat 11 is installed at the upper end of the water supply pipe P, which is open upwards. The valve seat 11 has a through hole that penetrates vertically, and water supplied from the water supply pipe P can flow upwards through the through hole in the valve seat 11.

[0024] The yoke 20 supports the valve stem 12 so that it can move up and down. The yoke 20 is fixed to the upper part of the valve seat 11. The valve stem 12 is positioned to pass through the upper part of the yoke 20 (connecting part 22, which will be described later) vertically. A through hole is formed in the upper part of the yoke 20 (connecting part 22) through which the valve stem 12 can be inserted, but this through hole is not shown in this embodiment.

[0025] A valve body 13 is provided at the lower part of the valve stem 12. The valve body 13 is positioned above the valve seat 11. The valve body 13 is shaped to be able to close the through hole of the valve seat 11 from above. A handle 14 is rotatably mounted on the upper side of the yoke 20. The handle 14 is fitted to the valve stem 12 by a screw. By rotating the handle 14, the valve stem 12 and the valve body 13 can be moved up and down.

[0026] By rotating the handle 14 in one direction and lowering the valve body 13, the through-hole of the valve seat 11 can be closed by the valve body 13. Conversely, by rotating the handle 14 in the other direction and raising the valve body 13, the through-hole of the valve seat 11 can be opened. In this way, the water supply pipe P can be opened and closed by rotating the handle 14.

[0027] The valve drive mechanism 30 shown in Figure 1 is for driving the valve opening / closing mechanism 10. The valve drive mechanism 30 is attached to the upper part of the yoke 20 via a mounting member 100, which will be described later. The valve drive mechanism 30 mainly comprises a housing 31, a motor 32, a connecting part 33, and a control unit 34.

[0028] The housing 31 is fixed to the upper surface of the mounting member 100. Other components constituting the valve drive mechanism 30 (such as the motor 32) are appropriately housed in the housing 31. The motor 32 is the drive source for rotating the handle 14. The output shaft of the motor 32 is connected to the handle 14 via the connecting part 33. In this way, the handle 14 can be rotated by driving the motor 32.

[0029] The control unit 34 is for controlling the operation of the motor 32. The control unit 34 can control the water supply to the rice paddy by driving the motor 32 based on various information (for example, the water level of the rice paddy, the weather, etc.).

[0030] The yoke 20 and the mounting member 100 attached to the yoke 20 will be described below.

[0031] As shown in Figures 2 to 4, the yoke 20 mainly comprises a support column 21 and a connecting portion 22.

[0032] The support column 21 is a rod-shaped (columnar) section formed with its longitudinal direction oriented vertically. A pair of support column 21s are provided, one on the left and one on the right. A planar outer upper surface 21a perpendicular to the longitudinal direction is formed on the upper surface of the support column 21. The pair of support column 21s are arranged with an appropriate interval between them.

[0033] The connecting portion 22 is the part that connects the upper parts of a pair of support columns 21. The connecting portion 22 is formed so that its longitudinal direction is oriented left to right. One end of the connecting portion 22 is connected to the upper part of one support column 21, and the other end is connected to the upper part of the other support column 21. The upper surface of the connecting portion 22 includes a pair of left and right inclined surfaces (inclined surfaces 22a) that slope upward inward from the left and right outer upper surfaces 21a, and a horizontal surface (central upper surface 22b) formed in the center left and right, parallel (horizontal) to the outer upper surfaces 21a. In this way, the left and right central parts of the connecting portion 22 are formed to bulge upward.

[0034] In the yoke 20, the pair of support columns 21 and connecting columns 22 are integrally formed. The yoke 20 is formed to have a constant thickness in the front-rear direction.

[0035] The mounting member 100 shown in Figures 2 to 4 is a member for attaching the valve drive mechanism 30 to the yoke 20 (valve opening / closing mechanism 10). The mounting member 100 mainly comprises a first mounting portion 110 and a second mounting portion 120.

[0036] The first mounting portion 110 is placed on the upper surface (outer upper surface 21a) of the yoke 20 and supports the valve drive mechanism 30. The first mounting portion 110 mainly comprises a bottom portion 111, an upper portion 112, and a connecting portion 113.

[0037] The bottom portion 111 is the lower part of the first mounting portion 110. The bottom portion 111 is formed in a flat plate shape with its plate surface facing up and down. A pair of bottom portions 111 are formed, one on the left and one on the right. The distance between the pair of bottom portions 111 is formed to be approximately the same as the distance between the pair of left and right support columns 21 of the yoke 20. The bottom portion 111 mainly comprises a mounting portion 111a and a connecting portion 111b.

[0038] The mounting portion 111a is the part that is mounted on the outer upper surface 21a of the yoke 20. The connecting portion 111b is the part that is connected to the second mounting portion 120. The connecting portion 111b is formed on both the front and rear sides of the mounting portion 111a. The connecting portion 111b is formed to protrude outward from the front and rear, and inward from the left and right sides, from the mounting portion 111a. A through hole 111c is formed at the inner end of the connecting portion 111b, passing through the connecting portion 111b vertically.

[0039] As shown in Figures 3 to 6, when the mounting portion 111a is placed on the outer upper surface 21a of the yoke 20, the connecting portion 111b is positioned to protrude forward and backward from the yoke 20. Also, when the mounting portion 111a is placed on the outer upper surface 21a of the yoke 20, the pair of front and rear connecting portions 111b are positioned to sandwich the bulging portion (the portion where the inclined surface 22a is formed) of the connection portion 22 of the yoke 20 from the front and back. This makes it easy to position the first mounting portion 110 relative to the yoke 20.

[0040] The upper surface portion 112 constitutes the upper part of the first mounting portion 110 and is the portion on which the valve drive mechanism 30 is mounted. The upper surface portion 112 is formed in a flat plate shape with its plate surface facing up and down. The upper surface portion 112 is formed in a long, elongated shape from left to right. A through hole 112a is formed in the center of the upper surface portion 112, penetrating it vertically. The upper surface portion 112 is formed with an appropriate vertical gap between it and the bottom surface portion 111.

[0041] The connecting portion 113 is the part that connects the left and right bottom portions 111 and the top portion 112. The connecting portion 113 is formed in a flat plate shape with its plate surface facing left and right. A pair of connecting portions 113 are formed, one on the left and one on the right. The left connecting portion 113 is formed to connect the left end of the left bottom portion 111 and the left end of the top portion 112. The right connecting portion 113 is formed to connect the right end of the right bottom portion 111 and the right end of the top portion 112. The distance between the pair of left and right connecting portions 113 is formed to be slightly smaller than the left-right width of the yoke 20. As a result, when the first mounting portion 110 is attached to the yoke 20, the pair of connecting portions 113 are positioned inward from both the left and right sides of the yoke 20.

[0042] In the first mounting portion 110, the pair of bottom portions 111, the top portion 112, and the pair of connecting portions 113 are formed integrally. The first mounting portion 110 can be formed, for example, by appropriately cutting and bending a single sheet of material. In the first mounting portion 110, the front-to-back width of the top portion 112 and the pair of connecting portions 113 is formed to be constant. In contrast, the connecting portion 111b of the bottom portion 111 is formed to protrude front-to-back from the top portion 112 and the connecting portion 113. That is, the connecting portion 111b is formed so as not to overlap with the top portion 112 when viewed from above (see Figure 6(a)).

[0043] Furthermore, the connecting portion 111b of the first mounting portion 110 is formed to be located outside the outer surface (outward-facing side) of the yoke 20. In this embodiment, the connecting portion 111b is formed to be located outside the front and rear sides of both the front and rear sides of the yoke 20 (see Figure 6).

[0044] The second mounting portion 120, shown in Figures 2 to 4, is positioned below the upper surface of the yoke 20, facing the first mounting portion 110, and clamps the yoke 20 between the two. The second mounting portion 120 is formed in a flat plate shape with its plate surface facing up and down. The second mounting portion 120 mainly comprises a connecting portion 121 and a connecting portion 122.

[0045] The connecting portion 121 is the part that connects to the first mounting portion 110. The connecting portion 121 is positioned with its longitudinal direction facing front to back. The length of the connecting portion 121 in the front to back direction is formed to be longer than the front to back width of the yoke 20. Also, the length of the connecting portion 121 in the front to back direction is formed to be approximately the same as the front to back width of the pair of front and rear connecting portions 111b of the first mounting portion 110. A pair of connecting portions 121 are formed, one on the left and one on the right. The pair of connecting portions 121 are arranged with an appropriate gap between them in the left to right direction. The gap between the pair of connecting portions 121 is formed to be approximately the same as the inner width of the pair of left and right support columns 21 of the yoke 20. Through holes 121a are formed at both the front and rear ends of the connecting portion 121, penetrating the connecting portion 121 vertically. The through holes 121a of the connecting portion 121 are formed at positions corresponding to (overlapping in plan view with) the through holes 111c of the first mounting portion 110.

[0046] The connecting portion 122 is the part that connects the left and right pair of connecting portions 121. The connecting portion 122 is positioned with its longitudinal direction facing left and right. The connecting portion 122 connects the rear ends of the left and right pair of connecting portions 121.

[0047] In this way, the second mounting portion 120 is formed in a roughly C-shape with an open front when viewed from above.

[0048] The following describes how to attach the mounting member 100 to the yoke 20.

[0049] When the mounting member 100 is attached to the yoke 20, the first mounting portion 110 is positioned above the yoke 20, and the second mounting portion 120 is positioned below the connection portion 22 of the yoke 20.

[0050] In this configuration, the mounting portion 111a of the first mounting portion 110 is placed on the outer upper surface 21a of the yoke 20. Furthermore, by positioning the connecting portion 22 (bulging portion) of the yoke 20 between a pair of front and rear connecting portions 111b, the first mounting portion 110 can be easily positioned.

[0051] Furthermore, the connecting portion 121 of the second mounting portion 120 abuts against the lower surface of the connecting portion 22 of the yoke 20. At this time, the through hole 121a of the second mounting portion 120 is positioned to face the through hole 111c of the first mounting portion 110 in the vertical direction.

[0052] Next, bolt B is inserted from above through the through hole 111c of the first mounting portion 110 and the through hole 121a of the second mounting portion 120, and fastened to nut N located on the lower side of the second mounting portion 120 (see Figure 3). The nut N may be fixed to the second mounting portion 120 in advance by welding or the like. In this way, the yoke 20 is sandwiched from above and below by the first mounting portion 110 and the second mounting portion 120, thereby fixing the mounting member 100 (first mounting portion 110 and second mounting portion 120) to the yoke 20.

[0053] In this embodiment, since the first mounting portion 110 and the second mounting portion 120, which are opposite each other vertically, can be fixed with bolts B or the like, the mounting member 100 can be fixed to the yoke 20 relatively easily even when the working space on the sides of the yoke 20 and the mounting member 100 is limited.

[0054] As described above, the mounting member 100 according to this embodiment is A mounting member 100 for attaching a valve drive mechanism 30 to a valve opening / closing mechanism 10 for opening and closing a valve body 13, The valve opening / closing mechanism 10 has a first mounting portion 110 which is placed on the upper surface of the yoke 20 and supports the valve drive mechanism 30, A second mounting portion 120 is positioned below the upper surface of the yoke 20 so as to face the first mounting portion 110, and sandwiches the yoke 20 between itself and the first mounting portion 110, It is equipped with the following features. This configuration allows the mounting member 100 to be easily fixed to the yoke 20. In other words, by using a configuration that clamps the yoke 20 from above and below, the mounting member 100 can be easily fixed to the yoke 20 even when it is difficult to secure sufficient workspace in the surrounding area.

[0055] Furthermore, the first mounting portion 110 and the second mounting portion 120 are made of separate components. This configuration allows the mounting member 100 to be easily fixed to the yoke 20. In other words, by constructing the first mounting portion 110 and the second mounting portion 120 as separate components, the shape of each component can be simplified and miniaturized, making it easier to perform the fixing work even in a limited space.

[0056] Furthermore, the first mounting portion 110 is A pair of bottom portions 111 are placed on the yoke 20 and connected to the second mounting portion 120, The upper surface portion 112 on which the valve drive mechanism 30 is mounted, A pair of connecting parts 113 that connect the pair of bottom parts 111 and the top part 112, It is equipped with the following features. By configuring it in this way, the first mounting portion 110 can be made simple.

[0057] Furthermore, the bottom portion 111 is It comprises a connecting portion 111b connected to the second mounting portion 120, The aforementioned connecting portion 111b is The first mounting portion 110 and the second mounting portion 120 are formed so as not to overlap with the upper surface portion 112 when viewed from the direction in which they face each other (up and down direction). With this configuration, the connecting portion 111b does not overlap with the upper portion 112, making it easy to attach connecting devices such as bolts B.

[0058] Furthermore, the bottom portion 111 is It comprises a connecting portion 111b connected to the second mounting portion 120, The aforementioned connecting portion 111b is It is located on the outer surface of the yoke 20 (in this embodiment, both the front and rear sides). With this configuration, the connecting portion 111b is located outside the outer surface of the yoke 20, making it easy to attach connecting devices such as bolts B.

[0059] Furthermore, the pair of connecting parts 113 are The pair of connecting portions 113 are formed such that at least a portion of them is located inside the yoke 20 in the direction in which they face each other (left and right direction). By configuring it in this way, the first mounting section 110 can be made compact, and interference with surrounding components (for example, a cover to prevent scattering or a manhole to prevent backflow) can be prevented.

[0060] Although one embodiment of the present invention has been described above, the present invention is not limited to the above configuration, and various modifications are possible within the scope of the invention as described in the claims.

[0061] For example, the specific configuration of each part (yoke 20, mounting member 100, etc.) of the valve device 1 described in this embodiment is just one example, and the shape, dimensions, etc. of each part can be changed as desired.

[0062] Furthermore, although this embodiment shows an example in which the first mounting portion 110 and the second mounting portion 120 are made of separate components (see Figure 4, etc.), it is also possible to form the first mounting portion 110 and the second mounting portion 120 integrally. In this case, for example, the distance between the first mounting portion 110 and the second mounting portion 120 can be set in advance to match the vertical width of the yoke 20 (connecting portion 22) to be attached.

[0063] Furthermore, in this embodiment, a configuration is shown in which the yoke 20 (connecting portion 22) that bulges upward is sandwiched from the front and rear by a pair of front and rear connecting portions 111b formed on the mounting member 100 (see Figures 3, 4, etc.), but the present invention is not limited to this. That is, it is not necessarily required to sandwich the yoke 20 with the pair of front and rear connecting portions 111b. Therefore, for example, the mounting member 100 can also be applied to a yoke 20 whose upper surface does not bulge (the entire upper surface is formed as a flat surface).

[0064] Furthermore, although this embodiment shows an example in which the second mounting portion 120 is formed in a substantially C-shape in plan view, the shape of the second mounting portion 120 can be arbitrarily changed. Also, for example, the pair of left and right connecting portions 121 of the second mounting portion 120 can be made of separate members.

[0065] Furthermore, in this embodiment, as shown in Figure 3, an example is shown in which the pair of left and right connecting portions 113 of the mounting member 100 are located inside the left and right sides of the yoke 20, but the present invention is not limited to this. For example, as shown in Figure 7(a), it is also possible to configure the pair of left and right connecting portions 113 of the mounting member 100 to be located outside the left and right sides of the yoke 20. This makes it possible to secure a wider space inside the mounting member 100, making it easier to perform various tasks (for example, operation of the handle 14 by an operator, maintenance of various parts, etc.).

[0066] Furthermore, it is not necessarily required that the entire pair of left and right connecting portions 113 of the mounting member 100 be positioned inside or outside of the left and right sides of the yoke 20. Parts of the connecting portions 113 may be positioned inside, while other parts may be positioned outside. For example, Figure 7(b) shows an example where the lower part of the connecting portion 113 is positioned inside of the left and right sides of the yoke 20, and the upper part of the connecting portion 113 is positioned outside of the left and right sides of the yoke 20. Thus, the shape of the first mounting portion 110 can be changed as needed.

[0067] Furthermore, in this embodiment, the connecting portion 111b of the first mounting portion 110 is formed so as not to overlap with the upper surface portion 112 when viewed from the vertical direction (see Figure 6(a), etc.), but the present invention is not limited thereto. For example, as shown in Figure 8, the connecting portion 111b and the upper surface portion 112 can be formed to overlap when viewed from the vertical direction. In this case, as shown in Figure 8, a through hole 112b may be provided in the upper surface portion 112 at a position that overlaps with the through hole 111c of the connecting portion 111b. This allows tools used for fastening, such as bolts B, to be used through the through hole 112b, making it easy to fix the mounting member 100 to the yoke 20.

[0068] In this embodiment, the mounting member 100 is fixed to the yoke 20 by clamping it from above and below with the first mounting portion 110 and the second mounting portion 120 (see Figure 4, etc.). However, it is also possible to configure the mounting member to clamp the yoke 20 from the front and rear directions, for example. Below, a mounting member 200 (a modified example of the mounting member 100) that clamps the yoke 20 from the front and rear directions will be described.

[0069] The mounting member 200 shown in Figure 9 mainly comprises a bottom portion 211, a top portion 212, a connecting portion 213, and a clamping portion 214.

[0070] The bottom portion 211 is the part that rests on the yoke 20 (outer upper surface 21a). The bottom portion 211 is formed as a flat plate with its surface facing up and down. A pair of bottom portions 211 are formed, one on the left and one on the right.

[0071] The upper surface portion 212 constitutes the upper part of the mounting member 200 and is the part on which the valve drive mechanism 30 is mounted. The upper surface portion 212 is formed as a flat plate with its surface facing up and down. The upper surface portion 212 is formed as a long, elongated shape from left to right.

[0072] The connecting portion 213 is the part that connects the left and right bottom portions 211 and the top portion 212. The connecting portion 213 is formed in a flat plate shape with the plate surface facing left and right. A pair of connecting portions 213 are formed, one on the left and one on the right. The pair of left and right connecting portions 213 are formed so that when the mounting member 200 is attached to the yoke 20, they are positioned outside the left and right sides of the yoke 20.

[0073] The clamping portion 214 is the part that clamps the yoke 20 from the front and rear. The clamping portion 214 is formed in a flat plate shape with its plate surface facing front and rear. The clamping portion 214 is formed in a pair, front and rear, sandwiching the bottom portion 211. The distance between the front and rear clamping portions 214 is formed to be approximately the same as the front-to-back width (thickness) of the yoke 20. The clamping portion 214 is formed to extend downward from both the front and rear sides of the bottom portion 211. When the mounting member 200 is attached to the yoke 20, the clamping portion 214 is formed to be located inside the left and right sides of the yoke 20.

[0074] Furthermore, the mounting member 200 has reinforcing ribs 215 appropriately formed across the bottom surface 211, the top surface 212, and the connecting portion 213.

[0075] When attaching the mounting member 200 to the yoke 20, the bottom portion 211 is placed on the outer upper surface 21a of the yoke 20. At this time, the upper part of the yoke 20 is inserted between the front and rear clamping portions 214. In this state, the yoke 20 is clamped by the front and rear clamping portions 214 by using fasteners such as bolts B.

[0076] For example, as shown in Figure 10(a), a bolt B is inserted from one side (the front in the example) across the front and rear clamping portions 214, and a nut N can be fastened at the rear of the clamping portion 214. The fastening force of the bolt B and nut N allows the pair of clamping portions 214 to grip (hold) the yoke 20, thereby fixing the mounting member 200 to the yoke 20.

[0077] Alternatively, as shown in Figure 10(b), female threads can be formed on the front and rear clamping portions 214, and bolts B can be tightened into these female threads, pressing down on the yoke 20 from the front and rear with the tips of the bolts B. By fastening bolts B to the front and rear clamping portions 214 in this way, the yoke 20 can be clamped (gripped) by the pair of front and rear clamping portions 214 via the bolts B. In this case, it is also possible to provide a recess 20a in the yoke 20 for positioning the bolts B, as shown in the example figure.

[0078] As shown in Figure 10(c), it is also possible to fasten a bolt B to one of the clamping parts 214 (the front clamping part 214 in the example shown), and then press down on the yoke 20 from both the front and rear by the bolt B and the other (rear) clamping part 214. In this way, by fastening a bolt B to one of the clamping parts 214, the yoke 20 can be clamped (gripped) by the pair of front and rear clamping parts 214 via the bolt B.

[0079] Although Figures 9 and 10(a) show examples where bolt B is provided so as to penetrate the yoke 20 from front to back, it is also possible to provide bolt B in a position that does not penetrate the yoke 20 (for example, inside the pair of left and right support columns 21).

[0080] When the mounting member 200 is fixed to the yoke 20, the lower part (clamping portion 214) of the mounting member 200 is contained within the left-right width of the yoke 20. With this configuration, the mounting member 200 can be contained within the left-right width of the yoke 20 up to the same height as the upper surface (outer upper surface 21a) of the yoke 20. This allows the mounting member 200 to be attached even if, for example, a backflow prevention basin or the like is placed around the yoke 20 (immediately outside the yoke 20).

[0081] Furthermore, the upper part of the mounting member 200 (the part above the bottom surface 211) may be configured to be positioned outside the left-right width of the yoke 20. This configuration allows for a wider space inside the mounting member 200, making it easier to perform various tasks (for example, operation of the handle 14 by an operator, maintenance of various parts, etc.).

[0082] In Figure 9, an example is shown where the upper part of the mounting member 200 (the part above the bottom surface 211) is located outside the left-right width of the yoke 20. However, as shown in Figure 11, for example, it is also possible to configure the mounting member 200 so that the entire mounting member 200 fits within the left-right width of the yoke 20. By configuring it in this way, the mounting member 200 can be installed even if, for example, a backflow prevention trap or the like is placed not only around the yoke 20 but also around the mounting member 200.

[0083] Furthermore, in the above modified examples (Figures 9 and 11), an example is shown in which a bottom portion 211 is provided on the mounting member 200 and the bottom portion 211 is placed on the upper surface of the yoke 20, but it is not necessarily required to provide the bottom portion 211.

[0084] Furthermore, in the above embodiment, a mounting member 100 (see Figure 2, etc.) that clamps the yoke 20 from the top and bottom, and a mounting member 200 (see Figure 9, etc.) that clamps the yoke 20 from the front and rear directions have been described, but the present invention is not limited thereto, and it is also possible to configure the yoke 20 to be clamped from two different directions (for example, the top and bottom direction and the front and rear direction).
