Then, by inserting the cylindrical portion of the operation portion mounting tube 23 of the main body 2 into the inside of the cylindrical portion of the operation handle 3, the operation handle 3, the main body 2 and the operation portion mounting tube 23 are connected. The case where it fits is also included.

  Further, the operation handle 3 is attached to the main body 2 in a state in which a gap between the main body 2 and the operation handle 3 is reduced. In the present embodiment, “the gap between the main body 2 and the operation handle 3 is small” means that the gap is reduced by fitting the main body 2 and the operation handle 3, This includes the case where the axial distance between the main body 2 and the operation handle 3 is reduced by reducing the axial distance from the handle 3.

  As shown in FIGS. 6 and 7, a transmission member 5 described later is detachably attached inside the operation handle 3. The operation handle 3 rotates the valve shaft portion 44 of the valve body assembly 43 of the water stop cock portion 4 (described later) through a transmission member 5 described later by a rotation operation, thereby rotating the first tubular body 21. Rotation operation of the stop cock part 4 (after-mentioned) is performed so that the 1st flow path F1 inside may be opened and closed. The operation handle 3 is formed of a resin member, and the surface thereof is plated with metal.

  As shown in FIGS. 6 and 7, the operation handle 3 includes a cylindrical handle body 31 whose one end is closed, and a knob portion 32 as a protruding portion.

The main body 2 is engaged with the outer peripheral annular engagement convex portion 232. As described above, the operation handle 3 is attached to the operation portion attachment tube 23 of the main body portion 2 so as to be rotatable.

  In the present embodiment, as shown in FIG. 6, the axial top plate 312 side is separated from the engaging convex portion 313 on the inner side in the axial direction of the tubular portion 311 than the engaging convex portion 313. A ridge portion 314 extending to the end of the ridge is formed. The protrusions 314 are formed to facilitate the formation of the engaging protrusions 313 when the operation handle 3 is manufactured from a resin material. That is, the engaging convex portion 313 and the convex strip portion 314 are formed in a straight line in the axial direction of the cylindrical portion 311 in a state of being separated from each other, so that when the resin material is molded using the mold. The engaging projection 313 can be easily molded. However, in the present embodiment, the ridge portion 314 is not used when the operation handle 3 is engaged with the main body portion 2. Therefore, if it is not particularly considered to facilitate the formation of the engaging convex portion 313, only the engaging convex portion 313 may be formed without forming the convex strip portion 314.

  The three positioning linear portions 315 position the transmission member 5 with respect to the operation handle 3 when the transmission member 5 is fitted and attached to the operation handle 3. As shown in FIGS. 6 and 7, the three sets of positioning linear portions 315 are spaced apart in the circumferential direction on the inner peripheral surface of the cylindrical portion 311 at the end on the top plate 312 side of the cylindrical portion 311.

As shown in FIG. 6, the fitting concave portion 531 of the fitting hole 53 of the transmission member 5 is fitted to the fitting convex portion 441.

  As shown in FIG. 8, an O-ring 46 is attached to the outer peripheral surface of the end of the valve shaft 44 on the cylinder valve body 45 side in the axial direction. The O-ring 46 is disposed between the valve case 41 and the valve shaft 44 of the valve body assembly 43 when the valve case 41 and the valve body assembly 43 are combined. Thereby, the sealing property of the valve case 41 and the valve body assembly 43 is ensured.

  As shown in FIG. 8, the valve shaft portion 44 is formed with a ring groove 442 that is recessed along the circumferential direction on the end portion side on the cylinder valve body 45 side. A substantially C-shaped retaining ring 8 (see FIG. 3) is fitted in the ring groove 442. As a result, the ring groove 442 of the valve shaft portion 44 in a state where the valve body assembly body 43 is assembled to the valve case 41 by passing the valve shaft portion 44 through the large diameter opening portion 41b and the small diameter opening portion 41a of the valve case 41. By fitting the retaining ring 8 on the valve case assembly 43, the valve assembly assembly 43 is assembled to the valve case 41 in a state where it does not come out of the valve case 41.

  As shown in FIG. 8, the valve case 41 is formed in a cylindrical shape. The valve case 41 has a small-diameter opening 41a formed at one end in the axial direction, a large-diameter opening 41b formed at the other end in the axial direction, and a pair of positioning recesses 412 and 412. The valve case assembly 43 is attached to the valve case 41 so as to be rotatable with respect to the valve case 41. When attaching the valve body assembly 43 to the valve case 41, the valve shaft 44 side of the valve body assembly 43 is inserted from the large diameter opening 41b of the valve case 41, and the valve is inserted into the small diameter opening 41a. With the shaft portion 44 penetrating and protruding, it is inserted until the side surface of one end of the cylinder valve body 45 comes into contact with the inner peripheral edge of the small diameter opening portion 41a. The valve assembly assembly 43 is attached to the valve case 41 by fitting the retaining ring 8 (see FIG. 3) into the ring groove 442 of the valve shaft portion 44.

  The pair of positioning recesses 412 and 412 are formed to be recessed in the axial direction on the side surface of the peripheral edge in the radial direction of the small diameter opening 41 a at one axial end of the valve case 41.

  In the valve case 41, a pair of case side openings 411a and 411b penetrating the peripheral wall portion of the valve case 41 are formed at positions corresponding to the pair of cylinder side openings 451a and 451b of the cylinder valve body 45.

  A ring-shaped packing 47 is disposed on the periphery of the case-side opening 411a in the valve case 41. The ring-shaped packing 47 is sandwiched between the peripheral edge of the case side opening 411 a and the restraining ring 48 and is fixed to the valve case 41. The ring-shaped packing 47 comes into contact with the peripheral edge of the opening on the upstream side of the second tubular body 22 when the stop cock 4 is attached to the main body 2. Thereby, the sealing property of the valve case 41 and the 2nd pipe body 22 is ensured.

  An O-ring 42 is attached to the outer peripheral surface on one end side in the axial direction of the valve case 41. The O-ring 42 is disposed between the valve case 41 and the operation portion attachment pipe 23 when the water stop cock portion 4 is attached to the main body portion 2. Thereby, the sealing property of the valve case 41 and the operation part attachment pipe 23 is ensured.

  In the above stop cock portion 4, by rotating the operation handle 3, the cylinder valve body 45 of the valve body assembly 43 is rotated via the transmission member 5, so that the cylinder valve body 45 By matching the cylinder side opening 451a with the case side opening 411a of the valve case 41, the first flow path F1 of the first tubular body 21 can be opened as shown in FIG. When the first flow path F1 of the first tubular body 21 is opened, the water flowing through the first flow path F1 of the first tubular body 21 is circulated to the second flow path F2 of the second tubular body 22. Further, when the cylinder-side opening 451a of the cylinder valve body 45 is overlapped with the case-side opening 411a of the valve case 41, the overlapping area is changed so that the cylinder-side opening 451a is circulated into the second flow path F2 of the second tubular body 22. The amount of water is adjusted.

  On the other hand, by rotating the operation handle 3, the cylinder valve body 45 of the valve body assembly 43 is rotated via the transmission member 5, and the cylinder side opening 451 a of the cylinder valve body 45 is opened in the valve case 41. The first flow path F1 of the first tubular body 21 is blocked by not matching with the case side opening 411a, and water does not flow to the second tubular body 22.

  In the water faucet device 1 configured as described above, the diameter of the main body 2 and the diameter of the operation handle 3 are formed to be approximately the same, and the operation handle 3 is fitted and attached to the main body 2. By reducing the axial distance between the main body 2 and the operation handle 3, a gap between the main body 2 and the operation handle 3 is formed small. Thereby, since the main-body part 2 and the operation handle 3 are visually recognized by the external appearance in the shape of a cylinder, the design property can be improved.

  Moreover, in the water stopcock apparatus 1, when the knob | pick part 32 of the operation handle 3 is located in the side, the direction which the knob | pick part 32 protrudes is arrange | positioned along a horizontal direction, and it will be in a closed state. . This state is a water stop state of the water stop cock device 1, and the cylinder side opening 451 a of the cylinder valve body 45 does not coincide with the case side opening 411 a of the valve case 41. For this reason, the first flow path F1 of the first tubular body 21 is blocked, and water does not flow to the second flow path F2 of the second tubular body 22.

  On the other hand, from the water stop state of the water stop cock device 1, the operation handle 3 is rotated by 90 ° so that the knob 32 of the operation handle 3 is positioned upward (see FIGS. 2 and 4). In this state, the operation handle 3 is arranged so that the direction in which the knob portion 32 protrudes is along the flow direction of the water flowing through the second flow path F2 of the second tubular body 22 of the main body portion 2, and is in an open state. It becomes. This state is a water passing state of the water stop cock device 1, and the cylinder side opening 451 a of the cylinder valve body 45 coincides with the case side opening 411 a of the valve case 41. Therefore, as shown in FIG. 4, the first flow path F <b> 1 of the first tubular body 21 is opened, and water can be circulated to the second flow path F <b> 2 of the second tubular body 22.

  Here, a communication portion 331 and an opening 332 are formed in the knob portion 32. Thereby, when hot water is poured into the water stop cock device 1, the operation handle 3 is fitted and attached to the main body 2, or the axial distance between the main body 2 and the operation handle 3 is reduced. In a structure in which the gap between the operation handle 3 and the main body 2 is small, hot air can be released from the knob 32 to the outside by the communication portion 331 and the opening 332. Thereby, it can reduce that the operation handle 3 becomes hot.

  Moreover, in the water stopcock apparatus 1, the operation handle 3 may be rotated by mischief or the like. Therefore, in the present embodiment, as shown in FIG. 9, the transmission member 5 is used with the transmission member 5 connecting the operation handle 3 and the stop cock portion 4 removed from the stop cock device 1. The operation handle 3 can be engaged with the main body 2. FIG. 9 is a perspective view illustrating a case where the operation handle 3 is attached to the main body 2 with the transmission member 5 removed from the operation handle 3.

For this reason, as shown in FIG. 9, the outer peripheral annular engagement convex portion 232 of the main body portion 2 is removed from the stop cock device 1 with the transmission member 5 connecting the operation handle 3 and the stop cock portion 4 removed. In addition, the four engaging projections 313 of the operation handle 3 can be engaged. Thereby, even if the operation handle 3 is rotated by mischief, the transmission member 5 does not exist, and thus the water stop cock portion 4 is not rotated. Even when the transmission member 5 is not present, the operation handle 3 can be engaged with the main body 2. Therefore, it is possible to prevent the water stop cock portion 4 from being easily rotated while suppressing the deterioration of the design.
When operating the open / close state of the stop cock device 1 in the absence of the transmission member 5, the operation handle 3 is removed from the main body 2 and the valve shaft 44 of the stop cock portion 4 is replaced with a tool or the like. Rotate directly using

According to this embodiment, the following effects are produced.
In the present embodiment, the stop cock device 1 is capable of switching between an open state and a closed state, and includes a first flow path F1 and a second flow path F2 communicating with the downstream side of the first flow path F1.

And an operation handle 3 for operating the stop cock 4. The operation handle 3 is formed in a cylindrical shape and protrudes outward from the outer peripheral surface (side surface) of the main body 2 from the outer surface of the operation handle 3. The knob 32 has an opening 322 that communicates the inside and the outside of the cylindrical portion 311 of the operation handle 3.

  For this reason, the clearance gap between the operation handle 3 and the main-body part 2 is small by fitting and attaching the operation handle 3 to the main-body part 2, or making the axial distance of the main-body part 2 and the operation handle 3 small. In the structure, even when hot water flows, hot air flowing through the communication portion 321 can be discharged to the outside through the opening 322. Thereby, even if hot water flows, it can reduce that the operation handle 3 becomes hot.

  In the present embodiment, the knob 32 is used when operating the operation handle 3. Therefore, the knob 32 as the protruding portion can be provided with a function of operating the operation handle 3, and a natural appearance can be obtained as compared with the case where only the protruding portion is provided.

  Moreover, in this embodiment, the knob | pick part 32 is arrange | positioned so that it may protrude upwards in the outer surface of the operation handle 3, when the water stopper apparatus 1 is in an open state. Therefore, the hot air discharged from the opening 322 is easily directed upward. Thereby, even if hot water flows, since hot air is discharged so as to rise from the upper side of the operation handle 3 while avoiding the operation handle 3, it is possible to further suppress the operation handle 3 from becoming hot.

  In the present embodiment, the opening 322 opens on the main body 2 side of the knob 32. Therefore, when operating the knob portion 32, the opening 322 is located on the back side of the operation handle 3. Accordingly, since hot air is discharged from the back side of the operation handle 3, when the user operates the operation handle 3, heat from the hot air is discharged to the front side (user side) of the operation handle 3. Can be reduced. Therefore, it can further suppress that the operation handle 3 becomes hot.

  In the present embodiment, the operation handle 3 is formed of a resin material. Thereby, even if hot water flows, it can reduce that the operation handle 3 becomes hot. Further, the cost required for the material can be reduced as compared with the case where the operation handle 3 is made of a metal material. Moreover, when the knob | pick part 32 is shape | molded with a resin material, by providing the lightening part in the knob | pick part 32 by the communication part 321 and the opening part 322, the part where thickness is too thick is decreased, and sink (resin It is possible to reduce the occurrence of dents and dents on the surface of the molded product molded with the material. Therefore, when manufacturing the knob | pick part 32 with a resin material by shaping | molding, the quality at the time of manufacture can be improved by providing the lightening part in the knob | pick part 32 by the communication part 321 and the opening part 322.
