SUMMARY OF THE INVENTION

PROBLEMS TO BE SOLVED BY THE INVENTION

[0004] Here, a dimensional error may occur in the valve body with respect to the designed dimension. For example, in the case of a flange-connected valve body, a dimensional error may occur in the axial center position between the upstream flange and the downstream flange. In such a case, if a pipe is connected to a valve body with a dimensional error without any adjustment, an unreasonable force will be generated in the connected state, and as a result, problems such as fluid leakage at the connection portion may occur, which is not preferable.

[0005] Accordingly, an object of the present invention is to provide a support member that can reduce the possibility of causing unreasonable force in pipe connection even when a dimensional error occurs in the valve body.

MEANS FOR SOLVING THE PROBLEMS

[0006] The support of the present invention is a support connected to a pipe, and the support supports a valve body having a valve body side passage through which fluid passes according to the degree of opening, The main unit and The system includes a position adjustment member that is movably attached to the main body between the piping and the valve body, and which has a connecting passage formed therein that connects the flow path of the piping and the flow path on the valve body side, The position adjustment member is fixed between the piping and the valve body via a fixing portion. The aforementioned fixing is a fixing that follows the displacement of the axial position of the valve body between the upstream and downstream portions in a direction intersecting the axis of the connecting passage.

[0007] In this configuration, the support body is equipped with a position adjustment member, which is fixed in accordance with any displacement of the axial position of the valve body between the upstream and downstream flanges in a direction intersecting the axis of the connecting passage. Therefore, even if there is a dimensional error in the axial position of the valve body, the position adjustment member can absorb the dimensional error.

[0008] In the support, the position adjustment member may be attached to the main body with a gap provided in a direction intersecting the axis of the connecting path.

[0009] With this configuration, by providing a gap, the position adjustment member can be prevented from interfering with the main body when the position adjustment member and the fixing part absorb dimensional errors.

[0010] In the support, the main body houses the valve body. The position adjustment member is attached to the main body so as to cover the opening formed at the end of the main body. The valve body side flow path of the valve body supported by the main body may be connected to the flow path of the piping via the connecting passage.

[0011] With this configuration, the support can form a unit that houses the valve body.

[0012] In the support, the valve body has a valve body flange for connecting to the pipe, The position adjustment member may follow the radial deviation relative to the axial center of the pipe that is the center of the valve body flange.

[0013] According to such a configuration, it is possible to cope with manufacturing errors of the flange included in the valve body.

[0014] In the support, the fixing portion may be provided across the main body and the position adjustment member.

[0015] According to such a configuration, by adjusting the fixing position of the position adjustment member relative to the main body with the fixing portion, the dimensional error of the valve body can be absorbed. Effects of the Invention

[0016] From the above, according to the present invention, even when a dimensional error occurs in the valve body, the possibility of causing unreasonable force in the pipe connection can be reduced. Brief Description of the Drawings

[Figure 5] FIG. 5 is a cross-sectional view taken along the line V-V in FIG. 2. [Figure 6] FIG. 6 is an enlarged view of the main part of FIG. 5. Modes for Carrying Out the Invention

[0018] Hereinafter, an embodiment of the present invention will be described with reference to Figures 1 to 6. Note that the terms up and down in the following description are based on the directions shown in the drawings. In addition, the expressions "upstream side" and "downstream side" are based on the movement direction of fuel (fluid) when purging the fuel, as will be described later. Further, the "axial direction" refers to the axial direction of the support 1 (the left-right direction in Figures 5 and 6 (the X direction shown in the drawings)) in a state where the pipe A is connected to the support 1 on a straight line. The "radial direction" refers to the direction orthogonal to the aforementioned axial direction (the direction including the Y and Z directions shown in the drawings).

[0019] The support 1 according to the present embodiment is installed, for example, around an engine or the like to support a fuel purge valve of a marine engine. In order to purge fuel, the fuel to be purged (a fluid that is liquid or gas) is passed through, and a pipe A extending from the engine to the purge destination is provided. The pipe A of the present embodiment is a double pipe. Pipes A (A1, A2) are connected to the support 1 on the upstream side (engine side) and the downstream side (purge destination side). Between the upstream pipe A1 and the downstream pipe A2, a valve element B which is a part of a valve for adjusting the passage of the fuel to be purged is arranged. The valve element B is supported by the support 1.

[0020] In the present embodiment, the valve element B refers to a portion of a valve such as a fuel purge valve (a valve unit including a drive means) that has a valve-element-side flow path B1 through which a fluid such as fuel passes according to the opening degree. In order to adjust the magnitude of the opening degree, the valve-element-side flow path B1 has a moving member (not shown in Figures 5 and 6). The moving member rotates or moves in a linear direction in the space of the valve-element-side flow path B1, so that the cross-sectional area of the space through which the fluid flows in the valve-element-side flow path B1 can be increased or decreased, and the opening degree of the valve-element-side flow path B1 can be changed accordingly.

[0021] Valve body B is configured to be connected to piping A located outside of valve body B by a connection mechanism. In this embodiment, the connection mechanism on the valve body B side is a valve body flange B2 that makes a connection by surface contact. Note that the term "connection" is not limited to direct connection, but also includes connection via other members (in this embodiment, the upstream position adjustment member 121). Valve body flange B2 is provided on the upstream and downstream portions of valve body B, respectively. On the other hand, the connection mechanism on the piping A side is a piping flange A11 provided at the end of piping A to prevent fluid from leaking to the outside of the piping. The piping flange A11 is integrally connected to the end of piping A, for example, by welding.

[0022] The external shape of the support body 1 is either a frame shape with an internal space communicating with the outside, or a box shape with an internal space partitioned from the outside. The outline of the external shape of the support body 1 is, for example, a rectangular parallelepiped. The valve body B is arranged in the internal space of these frame-shaped or box-shaped structures. In other words, the support body 1 houses (contains) the valve body B. The operating mechanism, consisting of a drive source and a power transmission mechanism for operating the movable member provided in the valve body side flow path B1, is provided on the outside (partially inside) of the support body 1. In this embodiment, the operating mechanism is provided above the support body 1. In addition, at least at the upstream or downstream end of the support body 11, an opening 1a is formed which has a space that communicates the inside and outside of the support body 1. In this embodiment, openings 1a are formed at the upstream and downstream ends of the body 11 of the support body 1.

[0023] The support body 1 comprises a support body 11, a position adjustment member 12, and a fixing part 13. The support body 11 includes, for example, a frame 111 for forming the frame-like shape, a plate-shaped wall 112 attached to the frame 111, and a base 113 located below the frame 111 for positioning the support body 1 at the valve installation location. In this embodiment, the wall 112 is bolted to the frame 111. Furthermore, the operating mechanism for operating the movable member for adjusting the opening degree inside the valve body B is provided so as to penetrate the wall 112 located on the upper side, as shown in Figure 5. The opening 1a is formed so as to be surrounded by the frame 111 at the upstream or downstream end of the support body 11.

[0024] The upstream and downstream ends of the support body 11 are open at an opening 1a. As shown in Figures 5 and 6, the upstream opening 1a is covered by the upstream position adjustment member 121 after its position has been adjusted. In this case, a part of the upstream position adjustment member 121 is located inside the support body 11, and the other part is located outside the upstream side of the support body 11. The upstream position adjustment member 121 is fixed to the frame 111 by bolts 1311 which constitute a part of the upstream fixing part 131 of the fixing part 13.

[0025] Furthermore, as shown in Figures 5 and 6, the downstream opening 1a of the support body 11 is covered by the downstream position adjustment member 122 after its position has been adjusted. In this case, a part of the downstream position adjustment member 122 (all of the inner member 1221 and a part of the outer member 1222) is located inside the support body 11, and the other part (another part of the outer member 1222) is located outside the downstream side of the support body 11. The outer member 1222 of the downstream position adjustment member 122 is fixed to the frame 111 by bolts 1321 which constitute a part of the downstream fixing part 132.

[0026] The support body 11 houses the valve body B. This allows the support body 1 to form a unit housing the valve body B. The position adjustment member 12 is installed between the pipe A and the valve body B. The position adjustment member 12 is movably attached to the support body 11 and the valve body B. This allows the position adjustment member 12 to adjust its position between the pipe A and the valve body B. Note that the "movable position" state is the state before the position adjustment member 12 is fixed to the support body 11 and the valve body B by the fixing part 13, and after fixing, its position becomes fixed. The fixing is done via the fixing part 13 (upstream fixing part 131, downstream fixing part 132) which is positioned between the pipe A and the valve body B.

[0027] The position adjustment member 12 in this embodiment consists of an upstream position adjustment member 121 located on the upstream side (left side in Figures 5 and 6) and a downstream position adjustment member 122 located on the downstream side (right side in Figures 5 and 6). Both have a circular cross-sectional shape perpendicular to the axial direction.

[0028] The upstream position adjustment member 121 has a connecting passage 1211 that connects the flow path of the piping A, which allows fluid to pass between it and the valve body B, and the valve body side flow path B1 of the valve body B, so that fluid can pass through. Therefore, the valve body side flow path B1 of the valve body B, which is supported by the support body 11, is connected to the flow path of the piping A (the inner flow path of the double pipe) via the connecting passage 1211 of the upstream position adjustment member 121 on the upstream side. The upstream position adjustment member 121 is attached to the support body 11 so as to cover the opening 1a formed at the upstream end of the support body 11. The upstream position adjustment member 121 is attached to the support body 11 (specifically the frame 111) with a gap S1 in the direction intersecting the axis of the connecting passage 1211. The "axis" refers to a virtual axis in the connecting passage 1211 that passes through the center of the cross-section perpendicular to the direction of movement of the fuel fluid. In order to provide the gap S1 in this way, a recess 1212 is formed in the radially recessed direction on the outer circumference of the upstream position adjustment member 121, specifically in the portion that coincides with the inner circumferential surface of the frame 111 in the axial direction. The recess 1212 is provided around the entire circumference of the upstream position adjustment member 121. Because the recess 1212 is recessed in the radial direction, a gap S1 is secured in the radial direction, allowing the upstream position adjustment member 121 to be moved relative to the support body 11 by the amount of this gap S1. Therefore, even if there is a dimensional error in the upstream valve flange B2 and position adjustment is required, the upstream position adjustment member 121 can be shifted radially by the amount of the gap S1, so that the upstream position adjustment member 121 fixed to the valve flange B2 does not interfere with the frame 111.

[0029] In this embodiment, the upstream position adjustment member 121 is attached to the support body 11 by a bolt 1311 shown in the lower left of Figure 6. The upstream position adjustment member 121 is also provided with a bolt hole 1213 for fixing the valve flange B2 of the valve body B. In this embodiment, it is a bottomed hole with a female thread formed therein. The upstream position adjustment member 121 and the valve body B can be bolted together by screwing a bolt 1214 into the bolt hole 1213 through the through hole in the valve flange B2. Although only one bolted state is shown in Figures 5 and 6, in reality, there are multiple bolts in the circumferential direction, the same number as the fixing holes in the valve flange B2. In addition, a pipe flange A11, which is, for example, welded to the end of the pipe A, is fixed to the upstream position adjustment member 121 by bolting. Incidentally, the pipe flange A11 is not a component of the support body 1. The bolt fastening positions of the upstream position adjustment member 121 and the pipe flange A11, and the bolt fastening positions of the upstream position adjustment member 121 and the frame 111 are set to be different in the circumferential direction, so that the bolts do not interfere with each other. In addition, O-rings are provided at the joint portions of the upstream position adjustment member 121 with the support body 11, the valve flange B2, and the pipe flange A11, respectively, to prevent fluid leakage from the joint portions.

[0030] Furthermore, the upstream position adjustment member 121 has a connecting passage 1215 that communicates with the outer flow path of the double-walled pipe A (A1) and opens to the internal space of the support 1. The pipe flange A11 is provided with a through hole A111, which connects the outer flow path of the double-walled pipe to the connecting passage 1215 of the upstream position adjustment member 121.

[0031] The downstream position adjustment member 122, like the upstream position adjustment member 121 described above, has a connecting passage 122a that connects the flow path of the piping A to the valve body B and the valve body side flow path B1 of the valve body B, allowing fluid to pass through. Here, the downstream position adjustment member 122 has an inner member 1221 located on the side closer to the valve body B in the axial direction and an outer member 1222 located on the side further away from the valve body B in the axial direction. The downstream position adjustment member 122 is composed of a combination of the inner member 1221 and the outer member 1222.

[0032] The inner member 1221 is disc-shaped and has a through-hole 12211 with a circular cross-section that penetrates axially at its radial center. The inner member 1221 is positioned with a gap S2 between it and the support body 11, in a direction intersecting the axis of the connecting passage 122a. Therefore, even if there is a dimensional error in the downstream valve flange B2, the inner member 1221 can shift radially by the amount of the gap S2, so that the inner member 1221 fixed to the valve flange B2 does not interfere with the frame 111.

[0033] The outer member 1222 has a larger diameter than the inner member 1221. The outer member 1222 is disc-shaped, but integrally has a tubular portion 12221 projecting upstream from its radial center. In this embodiment, the tubular portion 12221 is cylindrical and is inserted into the through hole 12211 of the inner member 1221 so as to be movable in the axial direction. The insertion state of the tubular portion 12221 is such that its axial direction is allowed to be tilted with respect to the axial direction of the through hole 12211 of the inner member 1221.

[0034] The connecting passage 122a of the downstream position adjustment member 122 is composed of a through hole 12211 in the inner member 1221 and a tubular portion 12221 of the outer member 1222 into which the through hole 12211 is inserted. The outer member 1222 is positioned with a gap S3 between it and the inner member 1221 in the direction along the axis of the connecting passage 122a. As a result, the valve body side flow path B1 of the valve body B supported by the support body 11 is connected downstream to the flow path of the piping A (the inner flow path of the double pipe) via the connecting passage 122a of the downstream position adjustment member 122, which spans the inner member 1221 and the outer member 1222. Of the downstream position adjustment member 122, the inner member 1221 is positioned to fit into an opening 1a formed at the downstream end of the support body 11, and the outer member 1222 is attached to the support body 11 so as to cover the opening 1a. The inner member 1221 is attached to the support body 11 (specifically the frame 111) with a gap S2 in a direction intersecting the axis of the connecting passage 122a. In this state, the inner member 1221 coincides with the inner circumferential surface of the frame 111 in the axial direction. Due to the gap S2 between the inner circumferential surface of the frame 111 and the outer circumferential surface of the inner member 1221 in the axial direction, the inner member 1221 and the outer member 1222, which partially overlaps the inner member 1221, can be moved relative to the support body 11. Furthermore, the positional relationship between the inner member 1221 and the outer member 1222 can be adjusted in the direction along the axis of the connecting passage 122a by the amount of the gap S3 in the direction along the axis of the connecting passage 122a.

[0035] In this embodiment, the downstream position adjustment member 122 is attached to the support body 11 by the bolt 1321 shown in the lower right of Figure 6. The outer member 1222 is directly bolted in this manner. The inner member 1221 is provided with a bolt hole 12212 for fixing the valve flange B2 of the valve body B. In this embodiment, this is a through hole with a female thread formed therein. The inner member 1221 and the valve body B can be bolted together by screwing a bolt 12213 into the bolt hole 12212 through the through hole in the flange of the valve body B. Although only two bolted locations are shown in Figures 5 and 6, in reality, there are multiple bolts in the circumferential direction, the same number as the fixing holes in the flange of the valve body B. In addition, in this embodiment, the outer member 1222 also functions as a pipe flange in the downstream pipe A2, and the end of the downstream pipe A2 is fixed to it by welding or the like. Furthermore, O-rings are provided at the joints of the downstream position adjustment member 122 with respect to the support body 11, the valve flange B2, and the inner member 1221 and the outer member 1222, thereby preventing fluid leakage from the joints.

[0036] The outer member 1222 has a passage that communicates with the outer flow path of the double-walled pipe A (A2), and opens to the internal space of the support 1 through the gap S3 between the outer member 1222 and the inner member 1221, and the gap S2 between the inner circumferential surface of the frame 111 and the outer circumferential surface of the inner member 1221. The outer member 1222, which also serves as the pipe flange on the downstream side, is provided with a through hole 12222, which connects the outer flow path of the double-walled pipe to the aforementioned passage of the downstream position adjustment member 122.

[0037] The position adjustment members 12 (each consisting of an upstream position adjustment member 121 and a downstream position adjustment member 122) are fixed between the piping A and the valve body B via a fixing part 13. The fixing part 13 is provided across the support body 11 and the position adjustment member 12. The fixing part 13 corresponds to a combination of a fastening member (specifically a bolt) for fixing the piping A and the position adjustment member 12, and a through hole (specifically a bolt hole) for receiving the fastening member.

[0038] The upstream position adjustment member 121 consists of a bolt 1311 that passes through the upstream position adjustment member 121 and is screwed into the support body 11, a bolt hole 1312 in the upstream position adjustment member 121, and a bolt hole 1313 in the frame 111. The diameter of the bolt hole 1312 in the upstream position adjustment member 121 is larger than the diameter of the hole corresponding to the nominal diameter of the bolt 1311. The bolt hole 1313 in the frame 111 is a bottomed hole with an internal thread formed therein.

[0039] The downstream position adjustment member 122 consists of a bolt 1321 that passes through the outer member 1222 and is screwed into the support body 11, a bolt hole 1322 in the outer member 1222, and a bolt hole 1323 in the frame 111. The bolt hole diameter of the bolt hole 1322 in the downstream position adjustment member 122 is larger than the hole diameter corresponding to the nominal diameter of the bolt 1321. The bolt hole 1323 in the frame 111 is a bottomed hole with an internal thread formed therein.

[0040] In this embodiment, the bolt holes 1312 and 1322 are larger in diameter than the bolts 1311 and 1321. The position adjustment member 12 can be adjusted radially and then fixed by the difference in diameter between the bolt and the bolt hole in the fixing part 13.

[0041] The combination of the upstream position adjustment member 121 and the fixing part 13 configured as described above allows for position adjustment in a direction intersecting the axis of the connecting passage 1211 (i.e., radial direction / Z direction shown in the figure, relative to the axis of the connecting passage 1211). This position adjustment can accommodate errors in the center position of the valve flange B2 between the upstream and downstream sides.

[0042] On the other hand, the downstream position adjustment member 122, in combination with the fixing part 13, allows for position adjustment in a direction intersecting the axis of the connecting passage 122a (i.e., radially relative to the axis of the connecting passage 122a) or in a direction along the axis of the connecting passage 122a (i.e., axially relative to the axis of the connecting passage 122a). This position adjustment can accommodate errors in the center position of the valve flange B2 between the upstream and downstream sides, as well as errors in the inter-face distance (inclination of the flange surface) between the upstream and downstream sides.

[0043] Furthermore, the downstream position adjustment member 122 can simultaneously adjust its position in a direction intersecting the axis of the connecting passage 122a (i.e., radial / Z direction relative to the axis of the connecting passage 122a) and in a direction along the axis of the connecting passage 122a (i.e., axial / X direction relative to the axis of the connecting passage 122a), thereby enabling position adjustment in an inclined direction relative to the axis of the connecting passage 122a. This position adjustment can accommodate errors in parallelism between the upstream and downstream sides of the valve body flange B2.

[0044] As described above, in the upstream portion of the support body 1, the support body 1 is equipped with an upstream position adjustment member 121, and this upstream position adjustment member 121 is fixed in accordance with the displacement of the axial position of the valve body B between the upstream and downstream flanges B2 in the direction intersecting the axis of the connecting passage 1211. Therefore, even if there is a dimensional error in the axial position of the valve body B, the dimensional error can be absorbed by the upstream position adjustment member 121. On the other hand, in the downstream portion, the support body 1 is equipped with a downstream position adjustment member 122, and the outer member 1222 of the downstream position adjustment member 122 is fixed to the support body 11 in accordance with the displacement relative to the inner member 1221 fixed to the valve body B. Therefore, even if there is a dimensional error in the valve body B, the dimensional error can be absorbed by the downstream position adjustment member 122.

[0045] Therefore, even if there is a dimensional error in valve body B, the possibility of strain on the connection of piping A can be reduced.

[0046] It should be noted that the support 1 of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, and a part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Furthermore, a part of the configuration of one embodiment can be deleted.

[0047] For example, the connection between pipe A and valve body B is not limited to the flange connection type of the embodiment described above, but may be a different type of connection (such as a screw connection).

[0048] Furthermore, the use of the support body 1 is not limited to fuel purging as in the above embodiment, but can be applied to various applications using the valve body B.

[0049] Furthermore, the configuration of the upstream position adjustment member 121 and the downstream position adjustment member 122 may be reversed in terms of the relationship between upstream and downstream compared to the above embodiment. That is, the upstream position adjustment member 121 of the above embodiment may be positioned on the downstream side, and the downstream position adjustment member 122 of the above embodiment may be positioned on the upstream side.

[0050] Furthermore, the support body 1 may be equipped with either the upstream position adjustment member 121 or the downstream position adjustment member 122. However, if the support body 1 is equipped with both the upstream position adjustment member 121 and the downstream position adjustment member 122, there is an advantage in that the adjustment range can be increased compared to if only one of them is equipped.
