It is a bottom view of a valve body when seeing XXVI (c) direction.

  With reference to these drawings, the ball tap 101 is installed in the water tank 116, connected to the water supply unit 110 connected to the water supply pipe 118, and below the water supply unit 110, and has a discharge port 131 formed below the water supply unit 110. A water discharger 130, a float mechanism 140 that transmits the vertical fluctuation of the water surface 117, and a lever mechanism 150 that is connected to the float mechanism 140 and controls the water discharge amount according to the vertical fluctuation of the water surface 117.

  The water supply unit 110 has a water supply port 111 connected to the water supply pipe 118 at a side portion thereof, and a drainage port 112 formed through a valve seat 132 at a lower portion thereof.

  The water discharge unit 130 is connected to the water supply unit 110 so as to surround the drain port 112, and houses the valve body 120.

  The valve body 120 is disposed below the drain port 112, is slidably installed up and down, and is configured to engage with the valve seat 132. The valve body 120 includes a valve main body 121 and leg portions 122.

  The float mechanism 140 includes a rod 141 connected to the lever mechanism 150 and a float 142 connected to the tip of the rod 141. The float 142 floats on the water surface 117 in the water tank 116 shown in FIG.

  The lever mechanism 150 is a so-called single type, and is disposed so as to contact the lower portion of the valve body 121 of the valve body 120 at the center thereof, thereby controlling the vertical movement of the valve body 120 according to the water surface 117. .

  The rod 141 connected to the lever mechanism 150 is connected to the float 142. The float 142 floats on the water surface 117 in the water tank 116 shown in FIG.

  In use, in the water tank 116 shown in FIG. 23, the float 142 fluctuates up and down as the water level fluctuates. As a result, the buoyancy of the float 142 that fluctuates up and down is transmitted to the lever mechanism 150 through the rod 141 connected to the float 142, and further transmitted from the lever mechanism 150 to the valve body 121, so that the valve body 120 moves up and down. Will slide. Therefore, since the engagement state between the valve main body 121 and the valve seat 132 changes, the ball tap 101 is opened or closed.

  Here, the process of the ball tap 101 moving from the closed state to the open state will be specifically described.

  Referring to FIG. 23, when the water level fluctuates and the water surface 117 descends, the float 142 descends. Thereby, the rod 141 connected to the float 142 is lowered. Then, the lever mechanism 150 connected to the rod 141 at one end rotates downward with the other end connected to the water discharger 130 as a rotation center. The valve body 120 descends as the lever mechanism 150 rotates. As a result, the valve body 120 is separated downward from the valve seat 132 in the engaged state. Accordingly, the ball tap 101 is opened, and the water that has entered the water supply port 111 from the water supply pipe 118 is discharged from the discharge port 131 through the valve seat 132 and supplied to the water tank 116.

  When the water level rises after the valve opening state described above and the float 142 rises to the specified position as the water surface 117 rises, the ball tap 101 is closed as shown in FIG. The water supply to the water tank 116 is stopped.

Japanese Patent Laying-Open No. 2015-004161

  FIG. 27 is a schematic cross-sectional view showing a use state of the ball tap shown in FIG.

  With reference to the figure, the ball tap 101 installed in the water tank 116 is in a valve-open state and supplies water to the water tank 116. Since the discharge port 131 of the ball tap 101 is located above the water surface 117, the water discharged from the discharge port 131 is directly supplied to the water surface 117. Therefore, when water is supplied vigorously, the water surface 117 in the water tank 116 is rippled, and the float 142 repeatedly fluctuates in the direction of the arrow. From the state indicated by the solid line, the position of the upper float 142a, The variation will repeat between the positions of the lower float 142b. Normally, when the float 142 is moved up to the specified position, the ball tap 101 is closed and the water is stopped. However, since the float 142 repeatedly fluctuates up and down, the ball tap 101 repeats the valve closing state and the valve opening state, causing a so-called shackle phenomenon, and the operation may not be stable.

  Therefore, the ball tap does not readily stop water, and discharge from the ball tap becomes intermittent, and inconveniences such as intermittent noise are often caused. In some cases, a phenomenon may occur in which the ripples are further amplified due to resonance between the intermittent discharge cycle and the fluctuation of the water in the water tank. When such a phenomenon occurs, discharge from the ball tap causes noise, large vibrations occur in the water tank, the water stop position of the ball tap is significantly different from the design value, or water hammer is applied to the water supply piping system. In some cases, this causes problems such as generating water and damaging the water supply piping system. Furthermore, the number of times of opening and closing the ball tap is increased, and the life of the seat packing is shortened. Due to this excessive opening and closing operation, the valve seat that comes into contact with the seat packing is worn, and water may leak even when the valve is closed.

  FIG. 5 is a partial cross-sectional view showing the storage of the valve body.

  Referring to FIGS. 1 and 4 in conjunction with the same figure, in use, the float 42 fluctuates up and down as the water level changes in the water tank 16 shown in FIG. As a result, the buoyancy of the float 42 that fluctuates up and down is transmitted to the lever mechanism 50 through the rod 41 connected to the float 42, and further transmitted from the lever mechanism 50 to the valve body 20, so that the valve body 20 moves up and down.

  Referring again to FIGS. 1 to 5, when the liquid level is lowered and the liquid level 17 is lowered, the float 42 is lowered. Thereby, the rod 41 connected to the float 42 is lowered. Then, the lever 51 of the lever mechanism 50 connected to the rod 41 rotates downward with the other end of the lever 51 connected to the liquid supply unit 10 as the rotation center. Next, the connecting member 52 connected to the lever 51 is lowered. The lever 53 connected to the connecting member 52 rotates downward with the other end of the lever 53 connected to the liquid discharge unit 30 as the rotation center. Furthermore, the valve body 20 descends as the lever 53 rotates downward. Eventually, the valve body 21 of the valve body 20 is separated downward from the valve seat 32 in the engaged state. Then, the ball tap 1 is opened as shown in FIG. 5, and the liquid that has entered the liquid supply port 11 from the water supply pipe 18 passes through the liquid discharge port 12 as shown by the arrow F1, and the valve seat 32 and the valve body. 21 flows out from between 21 (arrows F <b> 21, F <b> 31), passes from above to below the valve body 21, is discharged from the discharge port 31, and is supplied to the water tank 16.

  Here, since the valve body 20 functions as a deflecting unit that deflects the flow of the liquid passing from the drain port 12 to the discharge port 31 in the horizontal direction, the discharged liquid from the ball tap flows along the inner surface of the discharge port 31. By diffusing while flowing, a substantially conical shape is formed as shown in FIG. 1, and the undulation of the liquid surface due to the discharged liquid is suppressed. Thereby, the opening / closing operation of the valve body is stabilized, and the reliability of the liquid level control is improved.

  Specifically, a part of the liquid flowing downward from the drain port 12 to the discharge port 31 is deflected by the inclined portion 24a of the leg portion 22a as shown by the arrow F22, and the inclined portion 24a discharges the liquid. The liquid diffuses while flowing along the inner surface of the discharge port. For this reason, the effect | action which falls to a liquid level vigorously at the time of the liquid discharge from the discharge outlet 31 and makes a liquid surface ripple is reduced. Therefore, the effect of suppressing undulation can be adjusted according to the degree of inclination of the inclined portion 24a. The same applies to the inclined portion 24b of the leg portion 22b.

  Referring also to FIG. 4, the liquid flows are deflected in opposite directions (in other words, in the same circumferential direction indicated by arrow A1) by the inclined portions 24a and 24b of the pair of leg portions 22a and 22b. The effect of suppressing undulation is further improved.

  Referring to FIG. 5 again, the second portion 23b of the cover portion 23 can adjust the flow of the liquid as shown by the arrow F32 when the liquid is discharged, and collides with the lever 53 of the lever mechanism 50. It is possible to prevent the liquid from scattering. In particular, a phenomenon in which a part of the spout spouts out vigorously from the hole portion penetrating the lever mechanism 50 in the spout 30 as shown by a two-dot chain line arrow F40, and the spout spatters outside the water tank. Can be suppressed. Thereby, the suppression effect of undulation improves more.

  Further, the second wall 25b of the second portion 23b prevents the liquid from colliding with the side surface of the lever 53 of the lever mechanism 50 during liquid discharge, and the liquid is deflected by the second protrusion 27b as shown by an arrow F33. The

  Therefore, the stability of the lever mechanism 50 at the time of discharging is improved and the effect of suppressing undulation is further improved. The same applies to the first portion 23a.

  For this reason, referring also to FIG. 4, since the liquid flows are deflected in the opposite directions by the first protrusion 27 a and the second protrusion 27 b, the effect of suppressing undulation is further improved.

  More specifically, the liquid flow is deflected by the inclined portion 24a, the inclined portion 24b, the first protruding portion 27a, and the second protruding portion 27b to one side in the circumferential direction indicated by the arrow A1, while the liquid discharge causes the valve to The body 20 is in a state in which an urging force is exerted on the side opposite to the circumferential direction indicated by the arrow A1 with respect to the rotation of the shaft center. For this reason, the vibration of the valve body 20 at the time of liquid discharge is suppressed.

  From another viewpoint, the liquid flow is deflected in the opposite directions in the inclined portion 24a and the inclined portion 24b, and the liquid flow is deflected in the opposite directions in the first protruding portion 27a and the second protruding portion 27b. Therefore, the discharged liquid is evenly scattered without interfering with each other. As a result, the action of the discharged liquid squirting against the liquid surface is reduced, and the undulation of the liquid surface due to the discharged liquid is suppressed.

  With the configuration described above, it is possible to perform a stable operation with a sufficient sliding surface between the valve body and the liquid discharge part, while being a compact valve body, and without requiring additional parts. An anti-ripple effect can be exhibited.

  Since the valve body 63 according to this embodiment is basically the same as the valve body 20 according to the first embodiment, the difference will be mainly described.

  Referring to these drawings, the valve body 63 replaces the inclined portions 24a and 24b of the pair of leg portions 22a and 22b with bent portions 72a and 72b that bend inward in the valve body 20, and covers The first portion 23a and the second portion 23b of the portion 23 are replaced with protruding portions 75a and 75b, respectively. The connecting portion 29 connects the lower ends of the bent portions 72a and 72b.

  The bent portion 72a is provided with inclined protruding portions 73a and 74a at the lower end thereof, and the bent portion 72b is provided with inclined protruding portions 73b and 74b at the lower end thereof.
