Description

  The present invention provides a valve main body having a flow path, a water discharge valve device that is provided above the flow path of the valve main body and controls a water discharge amount, is provided to be rotatable relative to the valve main body, and the water discharge The present invention relates to a water supply valve composed of a spout for operating a valve device.

  Conventionally, as shown in FIG. 7, a spout (valve cap) 104 that is provided so as to be rotatable in a horizontal direction with respect to the valve body 102 having the flow path 121, and an upper part of the flow path 121 of the valve main body 102. A water supply valve 100 including a water discharge valve device 103 is known. In such a water supply valve 100, the water discharge end 144 side of the tip of the spout 104 is rotated in the horizontal direction with respect to the valve body 102, and the water discharge valve device 103 is interlocked to open and close the water discharge and discharge the water. The amount of water can be adjusted (see Patent Document 1).

  Specifically, the base end side of the flow path 142 of the spout 104 is formed by a fitting end portion 143 that is fitted on the valve main body 102. And the inner peripheral wall 143b which provided the coupling seat 143a couple | bonded with the water discharge valve apparatus 103 is formed in the fitting end part 143 inside. Here, by connecting the coupling seat 143a to the locking head portion 132a of the fixed seat 132, when the spout 104 is rotated, the movable valve disk 134 that engages with the engaging portion 132b of the bottom of the fixed seat 132. Rotate together.

  In the water supply valve 100 disclosed in Patent Document 1, the upper hole 134a of the movable valve disk 134 and the fixed valve disk 135 are rotated by directly rotating the water discharge end (tip) 144 side of the spout 104. Since the area of the overlapping area with the lower hole 135a changes, the amount of water discharged from the raw water inlet 102a of the valve body 102 can be controlled.

  Here, when the spout 104 is assembled, the amount of water discharged increases as the water discharge end 144 moves away from the wall surface (not shown) to which the water supply valve 100 is attached, that is, as it becomes orthogonal to the wall surface. In this case, when the water discharge end portion 144 approaches the wall surface to the left or the right, the water discharge state is provided so that the space of the spout 104 is not taken when not in use.

In addition, if the spout 104 is brought close to the wall surface, the necessary space is considerably reduced. Even when the spout 104 is attached to a general wash bowl, a kitchen sink, etc., the water discharge end 144 is used when washing the face wash, tableware, and cooking utensils. When it is not used without receiving the interference, it is also possible to prevent troubles such as interference with a person by bringing the water discharge end 144 close to the wall surface.

  However, as shown in FIG. 7, the coupling seat 143 a is formed so as to protrude into the flow path 142 in the middle of the fitting end 143, and in addition, inside the fitting end 143, Because the bolt 105 is connected to the locking head portion 132a of the columnar fixed seat 132 disposed substantially at the center, the cross-sectional area of the flow path 142 is partially narrowed by the coupling seat 143a and the fixed seat 132. It has a configuration.

  Furthermore, since the through hole of the bolt 105 is formed in the upper part of the outer peripheral surface of the spout 104, there is a problem that the layout of the spout 104 is necessarily limited when the tightening position of the bolt 105 is taken into consideration.

  An object of this invention is to provide the water supply valve which can ensure the cross-sectional area of a flow path large, and the freedom degree of the layout of a spout improves.

  A water supply valve according to the present invention is provided in a valve body having a flow path, a water discharge valve device that is provided above the flow path of the valve main body and controls a water discharge amount, and is rotatable relative to the valve main body. And a spout for operating the water discharge valve device, wherein the spout base end is provided with a fitting portion, and the water discharge valve device is connected to the spout and integrated with the spout. A hollow pipe-shaped rotation member that rotates, and a fitted portion that forms a flow path by fitting with the fitting portion is provided at a portion of the turning member that faces the fitting portion. The spout is capable of transmitting the rotational force of the spout to the rotating member, and an attachment member is provided for connecting the spout and the rotating member outside the spout base end. The amount of discharged water is controlled by rotating the To.

  In one embodiment of the present invention, the fitting portion is formed of a concavo-convex portion formed on the base end surface of the spout and spaced from the center of the flow path of the spout.

  In one embodiment of the present invention, the mounting member has a screw hole formed in an inner peripheral surface thereof, and is configured by an annular body coaxial with the spout and the rotating member, and slides along the outer peripheral surface of the spout. A stopper member that restricts the position of the mounting member is provided at both ends of the spout, and a screw portion that is screwed into the screw hole is formed on the outer peripheral surface of the rotating member. The spout is connected to a rotating member by screwing a screw hole and a screw portion.

  In one embodiment of the present invention, the water discharge valve device includes the rotating member, a non-rotatable fixed valve disk housed in the valve body, and the turning member housed in the valve body. The movable valve disc is integrally rotatable, and a second fitting portion is provided on a side of the turning member facing the movable valve disc, and the second fitting portion is provided on the movable valve disc. A second fitting portion that can be fitted is formed so as to rotate integrally, and the upper end of the valve body on the flow path side can be brought into contact with the second fitting portion, A rotation angle restricting portion for restricting the rotation angle of the second fitting portion is formed.

  In one embodiment of the present invention, the first seal member and the second seal member that seal between the valve main body and the fixed valve disk and between the movable valve disk and the rotating member, respectively. It is provided.

  According to the present invention, the fitting portion on the outer periphery of the spout base end and the fitted portion of the rotating member are fitted to each other to form a flow path, thereby forming a flow path along the central axis of the water supply valve. In addition, since a channel with few barriers can be formed, a large cross-sectional area of the channel can be secured.

  Therefore, the flowing water flowing in from the raw water inlet of the valve body passes through the flow path having a small number of barriers along the center of the water supply valve, so that the flow is smoothed without being suppressed in the middle.

  Furthermore, by connecting the spout and the water discharge valve device outside the base end of the spout, there is no need to forcibly bend the spout in consideration of the position of the mounting member, and the spout is limited in layout. There is no configuration.

  Thereby, since the freedom degree of the layout in a spout improves, the shape of a spout can consider the operativity.

An embodiment of the present invention will be described below with reference to the drawings.

  In the water discharge valve device 3, the valve case 31, the valve case guide 32, and the drive case 33 are integrally assembled and are unitized as shown in FIGS. 1 and 3.

  As shown in FIG. 2, the valve case 31 has a hollow pipe shape, includes a through hole 31 a coaxial with the flow path 21 of the valve body 2, and is assembled to the upper part of the flow path 21 of the valve body 2. The valve case 31 is formed with a screw hole 31b screwed into the screw portion 23 of the valve body 2 on the inner peripheral surface thereof so that the valve case 31 can be assembled to the upper part of the flow path 21. In addition, a drive case 33 that is rotatable with respect to the valve case 31 is provided in the upper end portion of the valve case 31 in the through hole 31a.

  A valve case guide 32 that can rotate integrally with the drive case 33 is attached to the upper ends of the valve case 31 and the drive case 33.

  Here, O-rings 31c and 32a as seal members are provided between the valve case 31 and the valve case guide 32, and between the valve case 31 and the drive case 33, respectively.

  At the center of the valve case guide 32, a through-hole 32c having a fitting groove 32b as shown in FIG. A hole having a diameter wider than that of the groove to be fitted 32b is formed in a portion of the through hole 32c other than the groove to be fitted 32b.

  The drive case 33 is provided with two convex claws 33a as shown in FIG. 3 (b) on the tip surface opposite to the valve case guide 32 at a position about 180 ° apart on the circumference of the bottom surface. ing.

  Returning to FIGS. 1 and 2, the upper valve disk 34 is a cylindrical member formed of a ceramic material, and is housed in the valve body 2 and the valve case 31. On the side surface of the upper valve disk 34, two recesses 34a are formed at positions separated from each other by about 180 °, and are fitted to the claws 33a of the drive case 33. Further, a recess 34 b is formed on the surface of the upper valve disk 34 facing the drive case 33, and the sleeve 36 can be accommodated between the recess 34 b and the drive case 33. Furthermore, a fan-shaped upper hole 34 c is formed in the recess 34 b of the upper valve disk 34.

  In the sleeve 36, fitting grooves 36a are formed on the outer peripheral surface thereof at appropriate intervals in the axial direction, and O-rings 36b as seal members are fitted in the fitting grooves 36a. By this sleeve 36, the seal between the drive case 33 and the upper valve disk 34 is reliably performed, and a straight flow path without unevenness can be formed by the flow path of the sleeve 36.

  The lower valve disc 35 is a cylindrical member formed of a ceramic material, like the upper valve disc 34, and is housed in the valve body 2 and the valve case 31. On the side surface of the lower valve disk 35, two recesses 35a are formed at positions spaced apart from each other by approximately 180 °. One side of the recess 35a is fitted with the tip of a lock pin 37 penetrating the valve body 2 through the pin hole 27, and the lower valve disk 35 is configured to be unrotatable. Further, a recess 35 b is formed on the surface of the lower valve disc 35 facing the valve body 2, and the sleeve 38 can be accommodated between the recess 35 b and the valve body 2. Furthermore, a fan-shaped lower hole 35 c is formed in the recess 35 b of the lower valve disk 35. 2 shows a state in which the upper hole 34c of the upper valve disk 34 and the lower hole 35c of the lower valve disk 35 are completely overlapped to obtain the maximum water discharge amount.

  In the sleeve 38, fitting grooves 38a are formed on the outer peripheral surface at appropriate intervals in the axial direction, and O-rings 38b as seal members are fitted in the fitting grooves 38a. By this sleeve 38, the seal between the lower valve disk 35 and the valve body 2 is surely performed, and a straight flow path without unevenness can be formed by the flow path of the sleeve 38.

  The spout 4 has a curved portion 41 on its distal end side, and a flow path 42 is provided therein, and a spout rib 43 and a spout 44 are provided at the proximal end and the distal end of the flow path 42, respectively. Yes.

  4A is a cross-sectional view taken along line AA in FIG. 2, and FIG. 4B is a bottom view showing the spout rib 43. The spout 4 is relatively horizontal with respect to the valve body 2. FIG. The spout rib 43 constituting the base end of the spout 4 is inserted into the through hole 32 c of the valve case guide 32 so as to be rotatable in the direction. On the outer peripheral surface of the proximal end of the spout rib 43, a concavo-convex portion 43b is formed by two convex portions 43b1 located at a distance L from the center of the flow path 43a. Here, the convex portion 43b1 is fitted in the fitting recessed groove 32b of the valve case guide 32, so that the flow path 43a and the through hole 32c communicate with each other in the spout 4 and the valve case guide 32. The flow path is formed and the spout 4 is positioned with respect to the valve case guide 32.

  Thus, the convex part 43b1 by the side of the spout rib 43 and the to-be-fitted groove | channel 32b of the valve case guide 32 mutually fit, and it forms along the center axis line of the water supply valve | bulb 1 by forming a continuous flow path. Since a channel with few barriers can be formed, a large cross-sectional area of the channel can be secured. Therefore, the flow of water flowing from the raw water inlet 2a (see FIG. 1 and the like) side of the valve body 2 passes through the flow path having a small number of barriers along the center of the water supply valve 1 so that the flow is suppressed halfway. There is no smooth.

  Further, since the flow path having a large cross-sectional area can be formed at the center of the water supply valve 1 without increasing the diameter of each member constituting the flow path of the water supply valve 1, the entire water supply valve 1 is compact as a result. Can be configured.

  Here, the outer surface of the spout rib 43 is provided with an O-ring 43c as a seal member and a stopper 43d, which will be described in detail later, at an appropriate interval in the axial direction, so that the spout 4 and the valve case guide 32 There will be no water leakage between the two.

  By the way, the spout 4 can be connected to and detached from the valve case guide 32, and a mounting screw 5 that can slide on the outer peripheral surface along the axial direction of the spout 4 is provided. The mounting screw 5 has a screw hole 51 formed on the inner periphery, and is constituted by an annular body coaxial with the spout 4, the valve case guide 32, and the drive case 33. Stoppers 43d and water outlets 44 (see FIG. 1) are provided at both ends of the spout 4, and the slide of the mounting screw 5 is regulated at both ends.

  A screw portion 32e that is screwed into the screw hole 51 is formed on the outer periphery on the upper side of the valve case guide 32, and the spout 4 is connected to the base end of the spout 4 by screwing the screw hole 51 and the screw portion 32e. Connected outside.

  Here, unlike the conventional water supply valve 100 (see FIG. 7) in which the through hole of the bolt 105 is formed at the upper part of the outer peripheral surface of the spout 104, the water supply valve 1 of this embodiment has a spout 4 and a valve case guide 32 ( By connecting the water discharge valve device 3) to the outside of the base end of the spout 4 using the mounting screw 5, it is not necessary to force the spout 4 to be bent in consideration of the tightening position of the mounting screw 5. The spout 4 is not subject to layout restrictions.

  Thereby, since the freedom degree of the layout in the spout 4 improves, the shape of the spout 4 can be made into the shape which considered operability according to the use of the water supply valve 1. For example, as shown in FIG. 1 and the like, the spout 4 side of the spout 4 can be formed to extend long upward, and the curved portion 41 at the upper end of the spout 4 can be laid out upward. Thereby, in the kitchen sink water tank etc., since the operation position of the spout 4 and the spout 44 can be arrange | positioned more upwards, the user can perform cooking work with a comfortable posture without bending a back. This will greatly reduce the burden.

  Further, the spout 4 is provided at both ends with the stopper 43d and a water outlet 44 having a diameter larger than that of the other so that the slide of the mounting screw 5 can be regulated at both ends, so that the water supply valve 1 is maintained. In such a case, the attachment screw 5 can be reliably prevented from being lost. Furthermore, in the insertion / extraction work of the spout 4, the attachment screw 5 can be slid and once moved away from the base end of the spout 4 toward the water outlet 44 at the front end.

  When the user rotates the spout 4 in the horizontal direction, in FIG. 1 and FIG. 2, the rotational force is transmitted to the water discharge valve device 3 by the convex portion 43b1 and the fitted concave groove 32b. Then, the claw 33a abuts and slides on the end surface 28 of the valve body 2 via the valve case guide 32 and rotates integrally. When the claw 33a rotates by a predetermined angle, the rotation regulating end 29a or 29b of the positioning rib 29 is obtained. The rotation angle of the spout 4 is regulated within a predetermined range.

  Here, in the conventional water supply valve 100 (see FIG. 7) described above, the spout 104 is connected to the center of the fixed seat 132 by the bolt 105. In the water supply valve 100, when the spout 104 is rotated, the action point of the force when transmitting the rotational force to the fixed seat 132 becomes the rotation center of the spout 104 and the fixed seat 132.

  On the other hand, when the spout 4 is rotated in the water supply valve 1 of the present embodiment, as described above, the convex portion 43b1 of the spout rib 43 is provided at a distance L from the center. The point of action of the force when the rotational force is transmitted to the valve case guide 32, the drive case 33, etc. is away from the center.

  In this way, by configuring the action point to be away from the center of rotation, the force required to rotate the valve case guide 32, the drive case 33, etc. can be kept as small as possible based on the lever principle. Therefore, the operability of the spout 4 can be improved.

  In addition, although the convex part 43b1 is formed in the spout rib 43 side and this convex part 43b1 is comprised so that it may fit in the to-be-fitted groove | channel 32b of the valve case guide 32, it is not necessarily limited to this. For example, a convex portion may be formed on the valve case guide 32 side, and the convex portion may be fitted into the concave portion of the concave and convex portion 43b on the spout rib 43 side.

  When the spout 4 is horizontally rotated in a direction in which water is discharged from the water discharge port 44, the water flow from the water source is sequentially from the flow path 21 of the valve body 2 to the flow path of the sleeve 36 and the lower part of the lower valve disk 35. After passing through the hole 35c, the upper hole 34c of the upper valve plate 34, the flow path of the sleeve 36, the flow path formed by the through hole 32c and the flow path 43a, it passes through the flow path 42 of the spout 4 from the water outlet 44 to the outside. Discharged.

  Here, as shown in FIG. 2, between the valve body 2 and the lower valve disk 35, between the upper valve disk 34 and the drive case 33, between the drive case 33 and the valve case 31, and between the valve case 31 and the valve case. O-rings 38b, 36b, 31c, 32a, 43c, and a stopper 43d are provided between the case guide 32 and between the valve case guide 32 and the spout rib 43, so that the flowing water does not have to be leaked. .

  FIG. 5 is an explanatory view showing the operation of the upper valve disk 34 and the lower valve disk 35 when the water supply valve 1 is in use, and the upper part of the upper valve disk 34 and the lower valve disk 35 is rotated by the clockwise rotation of the claw 33a. The hole 34c and the lower hole 35c are completely overlapped to reach the maximum water discharge amount.

  Here, when the upper hole 34c of the upper valve disk 34 and the lower hole 35c of the lower valve disk 35c are completely overlapped, the claw 33a comes into contact with the rotation restricting end portion 29a, and further rotation is performed. It is in an angular position where it becomes impossible.

  In the case of adjusting the water discharge amount to be small, if the claw 33a is rotated counterclockwise in FIG. 5, the upper valve disk 34 is rotated relative to the lower valve disk 35 of the fixed structure, and the upper valve The positional relationship between the upper hole 34c of the disk 34 and the lower hole 35c of the lower valve disk 35 is slightly shifted. Thereby, since the area of a superposition area becomes a little smaller than the maximum time, the amount of water discharge decreases a little.

  Here, when recovering the water discharge amount to a relatively large state, if the spout 4 is rotated clockwise, the area of the overlapping area of the upper hole 34c of the upper valve disk 34 and the lower hole 35c of the lower valve disk 35 is increased. Increases and the amount of water discharged can be restored to a relatively large state.

  The area of the overlapping area of the upper hole 34c of the upper valve disk 34 and the lower hole 35c of the lower valve disk 35, that is, the water discharge amount, can be arbitrarily controlled by the user by the rotation of the claw 33a. In this case, the upper hole 34c and the lower hole 35c can be shifted to the angular position where they abut against the rotation restricting end 29b, and the water can be shut off without completely shifting the upper hole 34c and the lower hole 35c. .

  Since the upper valve disk 34 and the lower valve disk 35 are formed of a ceramic material, the valve disks 34 and 35 are brought into close contact with each other by taking advantage of the smooth and glossy characteristics of the ceramic material. The force required to rotate the touch is not so great, and the user can easily operate.

  Even if a relative angular shift occurs between the upper valve disk 34 and the lower valve disk 35, the sleeve 38 and the sleeve 36 (see FIG. 2) cause a section in the section from the valve body 2 to the drive case 33. Sealability is reliably maintained.

  Here, in FIG. 5, the end face of the upper valve disk 34 is set so as to slightly protrude from the end face 28 of the valve body 2, and the claw 33 a of the drive case 33 is formed in the recess 34 a of the upper valve disk 34. Of these, it engages with a portion slightly protruding from the end face 28 and rotates integrally. Further, the claw 33a abuts against the rotation restricting end portions 29a and 29b of the end face 28 of the valve body 2, thereby restricting the rotation angle of the valve case guide 23, the drive case 33, and thus the spout 4 (see FIG. 1 and the like). To do.

  Thus, the claw 33a is configured to be able to contact the rotation restricting end portions 29a and 29b of the positioning rib 29 of the valve main body 2 while being fitted into the recess 34a of the upper valve disk 34. However, since it serves both as a role of rotating the upper valve disk 34 and a role of regulating the rotation angle of the spout 4, the configuration can be simplified.

  By the way, in embodiment mentioned above, as shown in FIG.1, FIG.2, etc., the attachment screw 5 is comprised by the spout 4 and the annular body coaxial with the valve case guide 32, and it can slide along the outer surface of the spout 4. However, the present invention is not necessarily limited to this. For example, as shown in FIG. 6 showing another embodiment, a flange portion 45 is formed outside the base end of the spout 4, and a plurality of screw holes are formed in the flange portion 45 and the distal end portion of the valve case guide 32. It may be.

  That is, the spout 4 and the valve case guide 32 are connected by tightening with the mounting screws 6 corresponding to the number of screw holes in a state in which the screw holes of both are combined. Here, instead of the stopper 43d of the first embodiment, a second O-ring 43e may be provided as shown in the figure to ensure sealing performance.

  In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
