  Further, in the two sets of locking structures 61 and 62, one locking convex portion 811 of the locking convex portions 811 and 812 of the secondary side valve body 8 is prevented from being erroneously assembled as shown in FIG. A recess 811d is formed. The misassembly prevention concave portion 811d is fitted into the misassembly prevention convex portion 713d of the locking concave portion 713 in the primary side valve body 7 when the primary side valve body 7 and the secondary side valve body 8 are assembled. The erroneous assembling prevention concave portion 811d is recessed from the front end in the rotation axis J direction of the trapezoidal extending portion 811b to the rear side. The other locking projection 812 is not formed with a mis-installation prevention recess.

  Thus, when the primary side valve body 7 and the secondary side valve body 8 are assembled, the erroneous assembling prevention concave portion 811d of the locking convex portion 811 in the secondary side valve body 8 becomes the locking concave portion in the primary side valve body 7. Since it can be assembled only to the mis-mounting prevention convex portion 713d of 713, it is possible to prevent erroneous assembly of the primary side valve body 7 and the secondary side valve body 8.

  As shown in FIGS. 4 to 6 and FIG. 9A, the secondary cylindrical member 81 includes a shower side opening 821 (water passage hole) and a shower side water passage that extends from the shower side opening 821. F1 (water flow path), a currant side opening 822 (water flow hole), and a currant side water flow path F2 (water flow path) extending from the currant side opening 822. Further, as shown in FIG. 9B, the secondary cylindrical member 81 includes a packing arrangement groove 841, a grease reservoir 842, and a grease supply groove 843.

  The shower side opening 821 and the currant side opening 822 can pass water from the primary side valve body 7 when the primary side valve body 7 and the secondary side valve body 8 are connected. As shown in FIG. 6 and FIG. 9B, the shower side opening 821 and the currant side opening 822 are centered at a portion facing the sliding plane 751b of the disk member 75 in the secondary side cylindrical member 81. Of the three arc portions divided into three corners, they are formed in a fan shape inside the two arc portions. The shower side opening 821 and the currant side opening 822 are formed in substantially the same size and shape as the disk opening 752 of the disk member 75 when the disk member 75 is rotated and stacked. However, the outer peripheral edges of the shower side opening 821 and the curran side opening 822 are formed in a circular shape, and are different in that the outer peripheral edge of the disk opening 752 of the disk member 75 is formed in a straight line. .

  As shown in FIG. 6, a shower side water passage F <b> 1 is connected to the shower side opening 821. As shown in FIGS. 5 and 6, the shower-side water passage F <b> 1 is formed so as to penetrate the secondary-side cylindrical member 81 in a direction parallel to the axial direction. The shower side water flow path F1 is a flow path that allows hot water to flow toward the currant water discharger 331 (see FIG. 1).

  As shown in FIG. 6, the currant side water passage F <b> 2 is connected to the currant side opening 822. As shown in FIGS. 4 and 6, the currant-side water passage F <b> 2 extends to the middle of the secondary cylindrical member 81 in the axial direction and penetrates from the middle of the secondary cylindrical member 81 in the radial direction. Formed. The currant-side water passage F2 is a passage through which hot water is circulated toward the currant-side water discharger 331 (see FIG. 1).

  The packing arrangement groove 841 is formed around the shower side opening 821 and the currant side opening 822 as shown in FIG. 6 and FIG. The packing arrangement groove 841 is formed in a portion of the secondary cylindrical member 81 facing the disk member 75 so as to surround the entire periphery of the shower side opening 821 and the currant side opening 822. As shown in FIG. 9B, the packing arrangement groove 841 has two fan-shaped annular shapes whose outer shapes are two fan-shaped portions among the three fan-shaped portions formed by dividing the central angle into three. The grooves 841a are connected to each other in a state where they are connected side by side in the circumferential direction. The two fan-shaped annular grooves 841a of the packing arrangement groove 841 are connected adjacent to each other in the circumferential direction, with a groove extending in the radial direction of the secondary cylindrical member 81 as a common groove at the connection portion. A packing member 85 is arranged in the packing arrangement groove 841.

  As shown in FIG. 6 and FIG. 9B, the packing member 85 is disposed around the shower side opening 821 and the curran side opening 822 by being arranged along the packing arrangement groove 841. The packing member 85 is disposed in contact with the sliding flat surface 751b (planar portion) of the disk member 75 of the primary side valve element 7. The packing member 85 is formed by connecting two fan-shaped fan-shaped annular portions 851 in a circumferential direction. The two fan-shaped annular portions 851 of the packing member 85 are connected adjacent to each other in the circumferential direction, with a portion extending in the radial direction of the secondary cylindrical member 81 as a common portion.

  The grease reservoir 842 is filled with grease. As shown in FIG. 6 and FIG. 9B, the grease reservoir 842 is a disk member 75 in the secondary cylindrical member 81 when the primary valve body 7 and the secondary valve body 8 are connected. In a portion opposite to, a depression is formed. The grease reservoir 842 is formed obliquely above the secondary cylindrical member 81. The grease reservoir 842 is provided with a shower-side opening 821 and a currant-side opening 822 among the three arc portions obtained by dividing the central angle into three at the portion of the secondary cylindrical member 81 facing the disk member 75. In a portion other than the portion, it is formed to be recessed in an arc shape. The grease reservoir 842 is filled with viscous grease. When the disc type valve device 6 is installed in the faucet device 1, the grease reservoir 842 is disposed obliquely above the grease supply groove 843 in a portion facing the disc member 75 in the secondary cylindrical member 81. The

  The grease supply groove 843 connects the grease reservoir 842 and the packing arrangement groove 841. The grease supply groove 843 extends obliquely downward from the grease reservoir 842 in the vicinity of the center of the portion of the secondary cylindrical member 81 that faces the disk member 75. The grease filled in the grease reservoir 842 passes through the grease supply groove 843 and is supplied to the packing arrangement groove 841.

  In the disc type valve device 6 configured as described above, when the switching handle 4 is rotated, the primary side valve body 7 is rotated, and the disc member 75 attached to the primary side valve body 7 is rotated. Since the disk member 75 is fixed to the primary side valve body 7, the primary side valve body 7 that is a movable valve rotates to rotate with respect to the secondary side valve body 8 that is a fixed valve. As shown in FIG. 10, the disk member 75 has a water stop position (see FIG. 10A) where the disk opening 752 is overlapped with the grease reservoir 842, and the disk opening 752 is on the secondary side. The shower side position (see FIG. 10B) that overlaps the shower side opening 821 of the valve body 8 and communicates with the shower side opening 821 and the disc opening 752 are the curran side opening of the secondary side valve body 8. It is configured to be able to rotate and move to a curran side position (see (c) of FIG. 10) that overlaps 822 and communicates with the curran side opening 822.

  Further, by adjusting the rotation angle of the disk member 75 at the shower side position (see FIG. 10B), the degree of overlap between the disk opening 752 and the shower side opening 821 is adjusted, so that the curran side The flow rate of water discharged from the water discharger 331 can be adjusted. Further, by adjusting the rotation angle of the disk member 75 at the curran side position (see FIG. 10C), the degree of overlap between the disc opening 752 and the curran side opening 822 is adjusted, and the curran side The flow rate of water discharged from the water discharger 331 can be adjusted.

  In this way, when the disc type valve device 6 is positioned at the water stop position (see FIG. 10A) by the rotation of the primary side valve body 7, the sliding plane 751b of the disc member 75, Water is stopped by the packing member 85 disposed around the shower side opening 821 and the currant side opening 822. In this state, the disk member 75 is attached to the disk holding portion 722, and with respect to the primary side cylindrical member 71 due to the water pressure applied to the primary side valve body 7 through the six hot water inflow openings 711. Then, it moves to the secondary valve body 8 side. Accordingly, the sliding flat surface 751b of the disk member 75 of the primary side valve body 7 can be brought into contact with the packing member 85 to stop the water, and the primary side valve body 7 and the secondary side valve body 8 are not formed long in the axial direction. The length of the disc-type valve device 6 in the length direction can be made compact.

  Moreover, in this embodiment, the primary side valve body 7 has the disk shaped disc member 75 which has the sliding plane 751b, and the disc member 75 is metal. Therefore, it is possible to reduce the formation of scratches on the disk member 75 due to dust or the like, for example, even when dust enters, rather than forming the disk member 75 from a resin material.

  Further, when the disk member 75 rotates, the grease accumulated in the grease reservoir 842 is pushed out by the disk member 75 through the grease supply groove 843 and into the packing arrangement groove 841. Thereby, even if the amount of grease in the packing arrangement groove 841 decreases, the grease is continuously supplied to the packing arrangement groove 841 through the grease supply groove 843. Thereby, the sliding resistance between the packing member 85 arranged in the packing arrangement groove 841 and the sliding plane 751b of the disk member 75 of the primary side valve body 7 can be continuously reduced.

  When the disc type valve device 6 is in a water stop state, as shown in FIG. 10A, the shower side opening 821 with the grease reservoir 842 facing the disc opening 752 of the disc member 75. Further, the packing member 85 disposed around the curran side opening 822 closes the shower side opening 821 and the curran side opening 822 and stops water by contacting the disk member 75. As a result, when the disc type valve device 6 is in a water-stopped state, the shower side opening 821 and the currant side opening 822 are closed, so that the grease filled in the grease reservoir 842 is removed from the shower side opening 821. And it is prevented from flowing out through the curran side opening 822.

  Further, the disk opening 752 of the disk part 751 of the disk member 75 is formed in a substantially triangular shape in which the opening area gradually increases from the vertex 752c toward the virtual base 752b. Therefore, the disk member 75 is rotated to gradually open the area through which hot water passes through the disk opening 752. Thereby, since hot water is not rapidly passed through the shower side opening 821 and the currant side opening 822, the water hammer phenomenon can be reduced.

  Further, the outer side 752 d of the disk opening 752 of the disk-shaped disk member 75 is not formed along the outer peripheral edge 751 c of the disk member 75. Therefore, when the disk member 751 rotates the disk member 75, the outer side 752d of the disk opening 752 does not continue to hit the same part of the packing member 85, but moves while abutting against different parts in the radial direction. As a result, the outer side 752d of the disk opening 752 does not continue to hit the same portion of the packing member 85, and the radial position is moved. Therefore, damage to the packing member 85 can be reduced.

As described above, according to the present embodiment, the following effects are produced.
The disc type valve device 6 of the present embodiment is a disc type valve device 6 including a cylindrical primary side cylindrical member 71 and a cylindrical secondary side cylindrical member 81, and has a secondary side cylindrical shape. The member 81 includes a rectangular extension portion 811a, 812a and a trapezoid extension portion 811b, 812b extending in the axial direction on the peripheral surface of the secondary side cylindrical member 81 and a peripheral side surface of the secondary side cylindrical member 81. And locking protrusions 811 and 812 configured to include triangular protrusions 811c and 812c protruding in a direction intersecting the axial direction from the shape extending parts 811a and 812a and the trapezoidal extending parts 811b and 812b. The primary cylindrical member 71 has locking recesses 713 and 714 that can be locked to the locking projections 811 and 812. Therefore, the cylindrical primary side cylindrical member 71 and the cylindrical secondary side cylindrical member 81 do not overlap in the radial direction on the peripheral surfaces of the primary side cylindrical member 71 and the secondary side cylindrical member 81. The locking projections 811 and 812 extending in the axial direction and the locking recesses 713 and 714 are fixed by being locked. Thereby, the increase in the radial direction is reduced, and the size in the radial direction can be made compact.

The engaging projections 811 and 812 constituting the shape are different from each other. Therefore, when the primary side valve body 7 and the secondary side valve body 8 are assembled, the locking concave portions 713 and 714 are assembled only to the locking convex portions 811 and 812 that can be assembled. Thereby, the incorrect assembly | attachment with the primary side valve body 7 and the secondary side valve body 8 can be prevented.

  In the present embodiment, the disc type valve device 6 includes the primary side valve body 7 and the secondary side valve body 8 in a connected state, and the peripheral surfaces of the primary side valve body 7 and the secondary side valve body 8 are the same. It is installed in the faucet device 1 in a covered state. Therefore, in a state where the disc type valve device 6 is installed in the faucet device 1, it is difficult to apply a force in a direction intersecting the axial direction of the disc type valve device 6, and the primary side valve body 7 and the secondary side valve body 8 are connected.
