Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a technique for floating balls of a ball tap provided in a tank for storing flush water in a toilet.

[Conventional technology]

The partial sectional front view of FIG. 6 shows the tank 1 for storing the wash water supplied to the toilet. In this tank 1,
Ball tap 2 that controls the supply of wash water into tank 1.
Is provided. A piston valve (not shown) is incorporated inside the ball tap 2, and the piston valve is opened and closed depending on the floating position of the floating ball 3. When the floating ball 3 is in the low position, the piston valve is opened to supply the supply water from the supply pipe 5 into the tank 1. When the floating ball 3 is in the high position, the supply of the supply water is stopped.

In such a tank 1, when the water pressure supplied from the supply pipe 5 is high, the pressing force applied to the piston valve provided inside the ball tap 2 is increased in order to ensure the water stopping operation of the ball tap 2. Will be needed. In the past, in order to increase the pressing force, the float 3 was replaced with a larger one, or the float 3 and the ball tap 2
The length of the connecting rod 4 for connecting and was adjusted.

[Problems to be solved by the device]

If it is necessary to replace the floating ball 3 with a larger one to increase the pressing force of the piston valve, prepare several types of floating balls having different volumes so that the floating pressure can be adjusted according to the supplied water pressure. I had to do it.

Further, when the pressing force of the piston valve is adjusted by adjusting the length of the connecting rod 4, there are the following problems. When a large number of tanks are installed in a building, a hotel, etc., the length of the connecting rod 4 of each individual tank must be adjusted, and the adjustment work is troublesome.

[Means for Solving the Problems]

The present invention has been made in view of the above conventional problems.

Thus, the means adopted by the present invention is such that a ball tap incorporating a piston valve and a floating ball are connected by a connecting rod, and the floating ball is positionally adjusted in the direction of the floating ball body and the connecting rod of the floating ball body. If possible, it will consist of at least one auxiliary float,
The auxiliary floating ball, the floating ball body, and the auxiliary floating balls are detachably attached by means of attachment / detachment such as concave / convex fitting and screw fitting.

[Action]

According to the means adopted by the present invention, since the removable auxiliary float is provided to adjust the position in the direction of the connecting rod of the float main body, the buoyancy of the float can be increased just by attaching the auxiliary float. Can be increased. Further, since the auxiliary floating balls are detachable, it is possible to connect some auxiliary floating balls to the floating ball body. Therefore, the pressing force of the piston valve of the ball tap moves the buoyancy center position of the whole floating ball toward the connecting rod depending on the number of auxiliary floating balls installed, and the buoyancy of the entire floating ball and the buoyancy center on which the buoyancy acts. Since the position and the distance between the piston valves can also be changed at the same time, the adjusting force with respect to the pressing force of the piston valves can be synergistically increased and increased stepwise. Furthermore, the auxiliary floating ball can be easily attached to the floating ball body by concave-convex fitting, screw fitting or the like. Therefore, the work of adjusting the buoyancy of the ball tap can be extremely simplified.

Therefore, by connecting some auxiliary floats 15 to the float main body 12, the buoyancy of the float 11 is gradually increased.

Next, a second embodiment will be described. As shown in FIG. 2, the floating ball 21 comprises a floating ball body 22 and an auxiliary floating ball 25. Floating ball body 22
Is made of plastic or the like and has a hollow can shape. On the side peripheral surface of the floating ball body 22, annular bulges 23 are provided at three positions at predetermined intervals. The auxiliary float 25 is made of plastic or the like and has a hollow donut shape. On the inner peripheral surface of the auxiliary floating ball 25, an annular recess 26 that fits into the annular bulge 23 of the floating ball body 22 is provided. As shown in the figure, by inserting the auxiliary floating ball 25 into the floating ball body 22, the buoyancy of the floating ball 21 can be increased.

Next, a third embodiment will be described. As shown in FIG. 3, the floating ball 31 comprises a floating ball body 32 and an auxiliary floating ball 35. This embodiment is substantially the same as the first embodiment except that the auxiliary floating ball 35 is detachably attached to the floating ball main body 32 by the concave-convex fitting in the first embodiment. In the case of this embodiment, the floating ball main body 32 and the auxiliary floating ball 35 are detachable by screws.

As described above in detail, the floating ball of the ball tap according to the present invention can be appropriately changed according to the embodiment.

[Effect of device]

According to the floating ball of the ball tap according to the present invention, by adding the auxiliary floating ball, the buoyancy center position of the entire floating ball is moved in the direction of the connecting rod, and the buoyancy of the entire floating ball and its buoyancy force act. Since the distance between the center of buoyancy and the piston valve is also changed at the same time, the pressing force of the piston valve provided on the ball tap can be increased synergistically, and the waterproof function can be ensured even when the water pressure of the makeup water is high. Can be Further, since the auxiliary floating ball can be connected to the floating ball body, the buoyancy of the floating ball can be adjusted in stages. Further, since the auxiliary float and the float main body or the auxiliary floats are detachable by concave and convex fitting, screw fitting, etc., the buoyancy adjustment work of the floating ball is extremely easy. Furthermore, when many tanks are installed in a place with high replenishment water pressure, the number of auxiliary floating balls for ball taps installed in one tank is determined, and the auxiliary floating balls installed in all other tanks are also uniformly determined. Therefore, the buoyancy adjustment work of the ball tap is very efficient.
