Definitions
- This invention relates to a joint such as a flange-type pipe joint.
- the joint includes first and second joint members having fluid passages communicating with each other, a seal member interposed between the butted end surfaces of both joint members, and screw means for coupling both joint members. What is known is well known.
- each joint member is composed of a sleeve and a flange, and the joint members are joined together by joining the flanges with a plurality of bolts.
- the in such a flange-type pipe joint the flanges of the joint members have the same shape and are joined by bolts and nuts (Patent Document 1), and screw holes are provided in either one of the flanges instead of the nuts.
- Patent Document 2 there is one that is coupled using only bolts
- An object of the present invention is to provide a joint with a reduced number of parts.
- a joint according to the present invention includes first and second joint members having fluid passages communicating with each other, a seal member interposed between the butted end surfaces of both joint members, and a bolt that couples both joint members.
- the bolt has a shaft portion in which a screw is formed in the tip portion and a male screw is not formed in the remaining portion, and the first and second joint members have the same shape.
- Each joint member is formed with a shaft insertion hole on the butt end face side and a screw hole extending to the anti-butt end face as a hole into which a bolt is inserted.
- a male screw is formed over almost the entire length of the shaft portion, whereas a screw portion is formed in the tip portion and the remaining portion has a shaft portion in which no male screw is formed. It is assumed that Each joint member is formed with a shaft insertion hole on the abutting end face side and a screw hole extending to the opposite abutting end face to thereby form the joint member in a shape corresponding to the bolt and the first and first Two joint members can be made into the same shape.
- the length of the shaft insertion hole and the length of the screw hole, the length of the bolt and the length of the male screw of the joint member are appropriately set in correspondence with each other.
- This joint is applied to, for example, a flange-type pipe joint, but is not limited to this, and can be applied in various ways to join two members.
- Each joint member may be composed of one member (a flange portion for coupling is integrally formed on the main body in which the fluid passage is formed), and may be composed of two or more members (inner circumference is A cylindrical sleeve member serving as a fluid passage and a flange member separate from the cylindrical sleeve member).
- each joint member includes a cylindrical sleeve member having an inner periphery serving as a passage and a flange member different from the cylindrical sleeve member. Both the sleeve member and the flange member have the same shape, and the shaft insertion hole and the screw are formed. It is assumed that a hole is provided in the flange member.
- the sleeve member and the flange member can be easily manufactured, and the number of parts can be reduced while suppressing an increase in manufacturing effort.
- the bolt has a shaft portion in which a screw is formed at the tip portion and a male screw is not formed in the remaining portion, and each joint member is abutted as a hole into which the bolt is inserted. Since the shaft insertion hole on the end face side and the screw hole extending to the end face to face the end face are formed, the first and second joint members can have the same shape. Thereby, the number of parts can be reduced compared with the conventional one in which the first joint member and the second joint member have different shapes.
- FIG. 1 is a longitudinal sectional view showing an embodiment of a joint according to the present invention.
- FIG. 2 is a longitudinal sectional view showing a state during the assembly of the joint according to the present invention.
- FIG. 3 is a longitudinal sectional view showing a flange member used in the joint according to the present invention.
- the joint (1) includes first and second joint members (2) and (3) having fluid passages communicating with each other. And an annular gasket (4) interposed between the joint members (2) and (3), and a plurality (one or more) of bolts (5) for joining the joint members (2) and (3). I have.
- Each joint member (2) (3) consists of a cylindrical sleeve (sleeve member) (11) whose inner periphery is a fluid passage and a flange (flange member) (12) which is a separate member.
- the sleeves (11) and the flanges (12) to be combined have the same shape.
- the gasket (4) is held by the retainer (6), and the retainer (6) is second (lower in the figure) by a snap ring (7) in which a metal wire having a circular cross section is formed in a C shape. It is held by the joint member (3).
- Each bolt (5) is composed of a head (13) with a hexagonal hole and a shaft (14), and the shaft (14) is formed with a screw (14a) at the tip and the remaining The part (14b) is not formed with male threads.
- the sleeves (11) of the joint members (2) and (3) are abutted against each other.
- a flange portion (11a) is provided on the outer periphery of the abutting end, and the gasket (4) and A recess (11b) for accommodating the retainer (5) is formed.
- each joint member (2) (3) has a through hole (12a) inserted through the sleeve (11) and is abutted against each other in a state of being fitted to the sleeve (11).
- a recess (12b) into which the flange portion (11a) of the sleeve (11) is fitted is formed on the inner periphery of the butt end portion of the flange (12).
- the flange (12) has a shaft insertion hole (15) on the butt end face side and a screw hole extending to the opposite butt end face as a hole into which the bolt (5) is inserted. 16) is formed.
- the length of the shaft insertion hole (15) and the length of the screw hole (16) are substantially the same.
- the length of the bolt (5) is approximately twice the length of the shaft insertion hole (15) + the length of the screw hole (16), and the length of the male screw (14a) of the bolt (5) is screw It is approximately equal to the length of the hole (16).
- the lengths of the shaft insertion hole (15) and the screw hole (16) can be freely changed depending on the use conditions and the like.
- the first flange having the shaft insertion hole and the second flange having the screw hole are provided in the conventional flange-type pipe joint using the bolt.
- the same flange (12) is used as a component of both joint members (2) and (3).
- the orientation of the flange (12) needs to be specified, and the pair of flanges (12) are arranged in a facing manner with the shaft insertion hole (15) on the end face side and the screw hole (16) on the opposite end face side. It is said.
- FIG. 2 shows a state during the assembly of the joint (1).
- the bolt (5) when the bolt (5) is screwed into the screw hole (16) of the flange (12) from the opposite end face side (upper side in the figure) of the first joint member (2), the bolt (5)
- the male screw portion (14a) passes through the screw hole (16), and in the state shown in FIG. 2, the axial movement relative to the first joint member (2) is free. Therefore, in this state, the bolt (5) can be fitted and screwed into the screw hole (16) of the flange (12) of the second joint member (3) from the butt end face side,
- the flanges (12) and (12) of the joint members (2) and (3) are joined to each other.
- the flange portion (11a) of the sleeve (11) is fitted into the recess (12b) at the butt end portion of both flanges (12) (12), and the bolt (5) is further tightened from this state. Then, the sleeves (11) and (11) are brought close to each other, and the gasket (4) disposed between the sleeves (11) and (11) is deformed to achieve a required sealing effect.
- the bolt (5) is screwed from the upper (first) joint member (2), but is screwed from the lower (second) joint member (2). You can also.
- the shape of the flange (flange member) (12) viewed from the axial direction is not shown, but the outer peripheral surface may be circular or polygonal (square, hexagonal, etc.).
- each joint member (2) (3) is composed of a sleeve (11) and a flange (12), but the structure of the joint member is not limited to this.
- Each joint member may be, for example, one member or may be composed of three or more members, and the shape of each member can be variously changed.
- the joint (1) described above can be applied to various uses for coupling using the flange (12) and the bolt (5).
- the joint of the present invention can be applied to a joint such as a flange-type pipe joint, thereby reducing the number of parts and contributing to labor and cost reduction when connecting fluid passages.
