Description

Technical Field

[0001] The present invention relates to a piping component having a handle mechanism for opening and closing valve components disposed in a fluid passage of a piping. Background Technology

[0002] Piping components include a handle mechanism for opening and closing valve members disposed within a fluid passage. For example, in the piping component shown in Patent Document 1, a valve member disposed within the fluid passage of the piping body and capable of displacement along the length axis of the fluid passage is opened and closed by rotating a handle disposed on the outside of the piping body. Specifically, the handle is fixed to a shaft extending along a rotation axis traversing the fluid passage, and the valve member is connected to this shaft via a connecting rod. When the handle is rotated about the rotation axis, the shaft rotates along with the handle, and the valve member connected to the front end of the connecting rod is displaced along the length axis of the fluid passage. The fluid passage is opened or closed by the displacement of the valve member along the length axis.

[0003] In the piping assembly shown in Patent Document 1, the handle mechanism consists of an inner shaft portion that extends transversely through the fluid passage and is rotatably mounted on the piping body, and an outer shaft portion that is fixed to the end of the inner shaft portion on the outside of the piping body by a connecting pin. The end of the outer shaft portion has a recess that coaxially receives the end of the inner shaft portion. With the end of the inner shaft portion received in this recess, the assembly is installed such that the connecting pin passes through both ends of the outer shaft portion and the inner shaft portion.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2021-21469 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] The handles of the aforementioned handle mechanisms are often relatively large to facilitate the opening and closing of the valve components. Furthermore, these handle mechanisms are frequently used in larger piping systems, tending to increase the overall weight of the piping components. Therefore, in cases where the piping components are accidentally dropped during transport or installation, the handle, which protrudes significantly from the piping body, can experience a significant impact when falling to the ground. This impact is transmitted to the shaft fixed to the handle, posing a risk of bending or breakage. In particular, when the shaft component consists of an inner and outer shaft connected by a connecting pin, the thinner and weaker inner shaft component is more likely to break.

[0009] Therefore, in view of the aforementioned problems of the prior art, the present invention aims to provide a piping component in which the shaft of the handle mechanism is difficult to break even when subjected to a large impact on the handle.

[0010] Solution for solving the problem

[0011] That is, the present invention provides a piping component comprising:

[0012] The main body of the piping system has a fluid passageway;

[0013] Valve components, disposed within the fluid passage; and

[0014] The handle mechanism is used to open and close the valve component.

[0015] in,

[0016] The handle mechanism has the following features:

[0017] An axial inner member is mounted to the piping body in such a way that it is rotatable about a rotation axis through which the fluid passage passes, and is connected to the valve member within the fluid passage, and the inner member has a first connecting end that protrudes outward from the piping body.

[0018] An outer member, configured to rotate about the axis of rotation on the outside of the piping body, the outer member having a handle and a second connecting end forming a recess for receiving the first connecting end; and

[0019] The connecting portion connects the first connecting end and the second connecting end in the rotational direction of the inner member in such a way that the outer member can pivot relative to the inner member about a pivot axis orthogonal to the rotation axis.

[0020] The piping body has a support surface located around the second connection end.

[0021] When a force is applied to the outer member in the direction of pivoting about the pivot axis, the second connecting end engages with the support surface and the outer member is supported by the piping body in the pivoting direction.

[0022] In this piping assembly, when a force is applied in the direction that pivots the outer member of the handle mechanism about its pivot axis, the second connecting end of the outer member engages with the support surface of the piping body, and the outer member is supported by the piping body in the pivot direction. Therefore, the aforementioned force can be absorbed by the piping assembly and is not substantially applied to the inner member. This prevents the inner member from bending or breaking due to a large force acting on it, particularly on the inner member of the handle mechanism.

[0023] Alternatively, the connection can be configured such that the first connection end and the second connection end are connected in such a way that the outer member can be displaced relative to the inner member in the direction of the pivot axis, and when the outer member is displaced relative to the inner member in the direction of the pivot axis, the second connection end of the outer member engages with the support surface and is supported.

[0024] This structure also allows for the avoidance of the force acting on the inner component when a force in the direction of the pivot axis acts on the outer component.

[0025] Specifically, it can be configured such that the connecting portion is a connecting pin that extends along the pivot axis through the first connecting end and the second connecting end.

[0026] Alternatively, the first connecting end can be configured such that the connecting pin passes through a first through hole, the second connecting end has a second through hole passes through, one of the first through hole and the second through hole has a first inner diameter that is larger than the outer diameter of the connecting pin in the direction of the rotation axis, and the outer member can also be displaced relative to the inner member about an axis orthogonal to the rotation axis and the length axis of the connecting pin.

[0027] According to this structure, regardless of the direction in which a force is applied that causes the outer member to pivot around the vicinity of the connection, the force can be made to not actually act on the inner member.

[0028] Alternatively, it can be configured such that one of the first through hole and the second through hole is an oblong hole with a second inner diameter that is approximately the same as the outer diameter of the connecting pin in a direction orthogonal to the axis of rotation and the axis of length.

[0029] Furthermore, it can be configured such that the first connecting end has an outer peripheral surface with a circular cross-section having a first diameter, the second connecting end has an inner peripheral surface with a circular cross-section having a second diameter and an outer peripheral surface with a circular cross-section having a third diameter, the support surface is an inner peripheral surface with a circular cross-section having a fourth diameter, the difference between the first diameter and the second diameter is greater than the difference between the third diameter and the fourth diameter, and the outer peripheral surface of the first connecting end and the inner peripheral surface of the second connecting end do not contact each other when the outer member is displaced relative to the inner member.

[0030] Alternatively, the outer component can be configured such that it has a first axial support portion and the piping body has a second axial support portion, the first axial support portion and the second axial support portion engaging in the direction of the rotation axis, thereby the outer component being supported by the piping component in the direction of the rotation axis.

[0031] Specifically, the piping body can be configured such that it has a cylindrical retaining portion protruding outward from the outer peripheral surface of the piping body in the direction of the rotation axis, the supporting surface is formed on the inner peripheral surface of the cylindrical retaining portion, and the second axial supporting portion is formed on the end face of the cylindrical retaining portion.

[0043] like Figure 1As shown, a piping component 10 according to one embodiment of the present invention includes a piping body 12 and a handle mechanism 14 mounted on the piping body 12. A corresponding connector component 1 is connected to the piping body 12 in a detachable manner.

[0044] like Figure 2 as well as Figure 3 As shown, the piping body 12 has a front main component 16, a rear main component 18, and an inner main component 20, which divide the fluid passage 22. A valve component 24 is disposed within the fluid passage 22, which moves in the direction of the length axis L of the piping body 12 to open and close the fluid passage 22. The piping body 12 also has a bearing component 26 on the lower side and a bearing component 28 on the upper side when viewed in the figure.

[0045] The handle mechanism 14 has an inner member 30 mounted on the piping body 12 in a manner that traverses the fluid passage 22, and an outer member 32 disposed on the outside of the piping body 12. The inner member 30 is a shaft-shaped member extending along the rotation axis R through which the fluid passage 22 traverses, and is held by a bearing member 26 on the lower side and a bearing member 28 on the upper side of the piping body 12 so that it can rotate about the rotation axis R. In addition, the inner member 30 is connected to the valve member 24 via a connecting rod member 34. The outer member 32 has an annular handle 36, an outer shaft portion 38 extending from the handle 36 toward the inner member 30 in the direction of the rotation axis R, and a circular plate-shaped member 40 clamped between and fixed to the handle 36 and the outer shaft portion 38. The inner member 30 has a cylindrical first connecting end 42 protruding outward from the pipe body 12, and the outer member 32 has a cylindrical second connecting end 46, which has a recess 44 that receives the first connecting end 42 in a coaxial shape. The first connecting end 42 and the second connecting end 46 are connected in the rotational direction by a cylindrical connecting pin (connecting part) 48.

[0046] When the corresponding connector 1 is inserted into the fluid passage 22 of the piping body 12 of the piping assembly 10, such as Figure 4As shown, connector 1 is connected to piping component 10. In this connected state, the locking member 50 of piping component 10 engages with the annular locking groove 52 of connector 1, and the locking member 50 is held in the position engaged with the annular locking groove 52 by sleeve 54. Thus, connector 1 is connected to and held by piping component 10. When handle 36 is turned in the connected state, inner component 30 connected by connecting pin 48 also rotates. Moreover, when inner component 30 rotates, valve component 24, which is connected to inner component 30 via connecting rod component 34, moves forward (to the right in the figure) along the length axis L. At this time, valve component 56 of connector 1 is also pressed and moved. Thus, as shown, the fluid passage 22 of piping component 10 and the fluid passage 58 of connector 1 are opened and interconnected.

[0047] like Figure 5A as well as Figure 6A As shown, the bearing member 28 on the upper side of the pipe body 12 forms a cylindrical retaining portion 60 that protrudes outward from the outer peripheral surface 12a of the pipe body 12 in the direction of the rotation axis R. The second connecting end 46 is located inside the cylindrical retaining portion 60. Furthermore, the first axial support portion 62, which is the lower surface of the circular plate member 40, engages with the second axial support portion 64, which is the end face of the cylindrical retaining portion 60, in the direction of the rotation axis R, thereby supporting the outer member 32 on the pipe member 10 in the direction of the rotation axis R. The first connecting end 42 of the inner member 30 has a first through hole 66 through which the connecting pin 48 passes, and the second connecting end 46 of the outer member 32 has a second through hole 68 through which the connecting pin 48 passes. The first through hole 66 is formed to accommodate the connecting pin 48, which is pressed into and fixed in the first through hole 66. On the other hand, the second through hole 68 has an inner diameter larger than the outer diameter of the connecting pin 48. When the outer component 32 rotates, the second through hole 68 engages with the connecting pin 48, and the outer component 32 is connected to the inner component 30 in the rotation direction via the connecting pin 48.

[0048] The first connecting end 42 has an outer peripheral surface 42a with a circular cross-section having a first diameter D1. The second connecting end 46 has an inner peripheral surface 46a with a circular cross-section having a second diameter D2 and an outer peripheral surface 46b with a circular cross-section having a third diameter D3. The cylindrical retaining portion 60 has an inner peripheral surface 60a with a circular cross-section having a fourth diameter D4. The first connecting end 42 and the second connecting end 46 are designed in shape and size such that the difference Δ1 between the first diameter D1 and the second diameter D2 is greater than the difference Δ2 between the third diameter D3 and the fourth diameter D4. That is, the gap between the first connecting end 42 and the second connecting end 46 is larger than the gap between the second connecting end 46 and the cylindrical retaining portion 60. Therefore, as will be described later, the outer peripheral surface 42a of the first connecting end 42 and the inner peripheral surface 46a of the second connecting end 46 do not contact each other.

[0049] The outer member 32 is connected to the inner member 30 in the rotational direction via the connecting pin 48, as described above, and can pivot relative to the inner member 30 about a pivot axis N1 that is approximately aligned with the length axis M of the connecting pin 48, which is orthogonal to the rotation axis R. Furthermore, the second through hole 68 of the second connecting end 46 is larger than the connecting pin 48, so the outer member 32 can also pivot relative to the inner member 30 and the connecting pin 48 about a pivot axis N2 that is orthogonal to both the rotation axis R and the length axis M. Moreover, the outer member 32 can also be displaced relative to the inner member 30 in the direction of the length axis M.

[0050] When the handle 36 of the outer member 32 is subjected to a force equal to that applied, and the outer member 32 pivots about the length axis M (pivot axis N1) of the connecting pin 48, as... Figure 5B As shown, the outer peripheral surface 46b of the second connecting end 46 engages with the inner peripheral surface (support surface) 60a of the cylindrical retaining portion 60 surrounding it, and the outer member 32 is supported on the pipe body 12 in the pivoting direction. More specifically, at positions P1 and P2, which are opposite to each other with respect to the imaginary plane passing through the rotation axis R and the pivot axis N1, the second connecting end 46 engages with the inner peripheral surface 60a, thereby preventing further pivoting of the outer member 32. At this time, the outer member 32 is also supported by the first axial support portion 62. Figure 5B The outer component, when viewed from the left, engages with the second axial support 64. Therefore, the outer component slightly shifts upwards as it is viewed from the center while pivoting around the connecting pin 48.

[0051] When the handle 36 of the outer member 32 is subjected to a force equal to that applied to the outer member 32, and the outer member 32 pivots about a pivot axis N2 that is orthogonal to the rotation axis R and the length axis M, as Figure 6BAs shown, the outer peripheral surface 46b of the second connecting end 46 engages with the inner peripheral surface 60a of the cylindrical retaining portion 60, and the outer member 32 is supported on the pipe body 12 in the pivoting direction. Similar to when pivoting about the length axis M (pivot axis N1) of the connecting pin 48, at positions P3 and P4 that are opposite to each other with respect to the imaginary plane passing through the rotation axis R and the pivot axis N2, the second connecting end 46 engages with the inner peripheral surface (support surface) 60a, thereby preventing the outer member 32 from pivoting further.

[0052] When the force applied to the handle 36 of the outer member 32 is equal to the force applied to the outer member 32, and the outer member 32 is displaced parallel to the direction of the length axis M of the connecting pin 48, such as Figure 6C As shown, the outer peripheral surface 46b of the second connecting end 46 engages with the inner peripheral surface 60a of the cylindrical retaining part 60 on one side, and the outer member 32 is supported on the pipe body 12 in the direction of the length axis M. It should be noted that, regardless of the direction of pivoting or displacement, the outer peripheral surface 42a of the first connecting end 42 and the inner peripheral surface 46a of the second connecting end 46 do not directly contact each other.

[0053] Thus, in this piping assembly 10, when a force is applied to the handle 36 of the handle mechanism 14 in a direction intersecting the rotation axis R, the outer member 32, including the handle 36, is supported in the cylindrical retaining portion 60 of the piping body 12. Therefore, the force on the handle 36 in the direction intersecting the rotation axis R is absorbed by the piping body 12, and thus does not substantially act on the inner member 30. Therefore, even if a large impact is applied to the handle 36, such as when the piping assembly 10 is dropped, a large force is not applied to the inner member 30, which has a smaller diameter and lower strength, thus preventing the inner member 30 from bending or breaking.

[0054] exist Figure 7 In another embodiment of the piping assembly shown, the second through-hole 168 formed at the second connecting end 146 of the outer member 132 is a hole with an elongated oval cross-section in the direction of the rotation axis R. The first inner diameter d1 of the second through-hole 168 in the direction of the rotation axis R is larger than the outer diameter of the connecting pin 148, and the second inner diameter d2 of the second through-hole 168 in the direction orthogonal to the rotation axis R and the length axis M is approximately the same size as the outer diameter of the connecting pin 148. The first inner diameter d1 is larger than the connecting pin 148, thereby allowing the outer member 32 to pivot about a pivot axis N2 orthogonal to the rotation axis R and the length axis M. On the other hand, the second inner diameter d2 is approximately the same size as the connecting pin 148, thereby eliminating or minimizing the play in the rotational direction between the outer member 132 and the inner member 130. This allows the operation of the handle to be directly transmitted through the inner member 130 and the valve member at its front end, resulting in good handle operability.

[0055] The embodiments of the present invention have been described above, but the present invention is not limited to these embodiments. For example, the connecting portion used to connect the first connecting end of the inner member and the second connecting end of the outer member in the rotational direction can also replace the connecting pin, and can be provided as a protrusion extending outward from the first connecting end, a protrusion extending inward from the second connecting end, or other structures. Alternatively, the connecting pin can be fixed to the second connecting end, and the connecting pin can pivot or displace relative to the inner member together with the outer member. Moreover, in the above embodiments, a gap is formed between the outer peripheral surface of the second connecting end and the inner peripheral surface (support surface) of the cylindrical retaining portion, but such a gap is not necessarily required. When configured without a gap, the outer member does not substantially pivot or displace relative to the inner member and the connector body, but the outer member and the inner member can be connected relative to each other in a pivoting and displaceable manner as described above, so that when a force in the direction of such pivoting and displacement is applied to the outer member, the outer member is supported by the support surface of the pipe body, and its force is absorbed by the pipe body and does not substantially act on the inner member.
