[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a ball tap provided in a water storage tank such as a flush toilet.

[0002]

2. Description of the Related Art For a ball tap in which a float floated above the water surface in a water tank keeps the water level in the water tank constant, the position of the valve body is adjusted so that the water stop level can be adjusted. There are things that I was able to do.

For example, in Japanese Examined Patent Publication No. 56-32509, a screw for adjusting the vertical position of the main valve is attached to the lower portion of the main valve which projects downward from the bottom of the ball tap body (body). Ball taps are listed.

[0004]

However, in the above-mentioned conventional ball tap, since the ball tap body faces directly above the water tank, it is difficult to operate the screw, and the position adjustment of the main valve, that is, the water stop level can be prevented. There was a difficulty in the operability for adjusting.

Further, since the screw is integrated with the main valve together with the valve shaft for attaching the operating rod connected to the float, only the main valve cannot be replaced, and
It is also difficult to replace only the screw, and the cost required for replacement is high.

On the other hand, since the main valve frequently moves up and down due to the fluctuation of the water level in the water tank, the screw is susceptible to vibration. If the set position of the screw changes due to vibration, the water stop level in the water storage tank also changes. Therefore, it is desirable that the screw be locked, but the conventional ball tap described above has no such locking means.

The present invention has been made in view of such circumstances.
An object of the present invention is to provide a ball tap in which the operation of changing the setting of the water stop level is easy, the set position of the water stop level can be kept constant, and the cost of replacing the valve element is low.

[0008]

The present invention comprises means for solving the above-mentioned problems as follows. That is, in the first invention, the valve body interlocking with the float is slidably housed vertically in the lower part of the fitting seat screwed vertically inside the body having the water intake port and the water discharge port, In a ball tap in which the water-stopping level can be adjusted by vertically adjusting the fitting sheet, a side projection portion of a retaining ring made of an elastic body is fitted in a notch formed in an upper peripheral edge of the body. The adjustment handle is fitted with the retaining ring so as not to rotate, and has a vertical groove formed in the retaining ring, and is detachably fitted and fixed to the upper portion of the fitting sheet through the retaining ring. Is set on the upper part of the body, and a vertical groove is formed in the lower part of the adjustment handle thereof, and the vertical position of the fitting sheet can be locked by engaging the vertical groove with the vertical groove of the retaining ring. The adjustment handle When releasing the engagement of the longitudinal groove together by moving is characterized by being configured to be able to change the set position of the fitting sheet by rotational operation of the adjustment handle.

According to a second aspect of the invention, a valve body interlocking with a float is slidably housed vertically in the lower part of a fitting seat screwed vertically up and down inside a body having a water intake port and a water discharge port. In a ball tap in which the watertight level can be adjusted by vertically adjusting the fitting sheet, a retaining ring made of an elastic body is fitted on the upper part of the inner peripheral surface of the body, and the retaining ring An adjusting handle, which is detachably fitted and fixed to the upper part of the fitting sheet via the above, is mounted on the upper part of the body, and a vertical groove is formed on the lower part of the adjusting handle, while the inner peripheral surface of the body is formed. A vertical groove is formed on the upper edge of the fitting seat, and the setting position of the fitting sheet can be locked by engaging the both vertical grooves with each other, and the adjustment handle is moved upward to release the engagement between the vertical grooves. Sometimes the adjustment handle turns It is characterized by being configured to be able to change the set position of the fitting sheet by the operation.

[0010]

[Operation] By moving the adjusting handle mounted on the upper part of the body upward to release the engagement between the vertical groove and the vertical groove of the retaining ring, and rotating the adjusting handle, the workability is improved. The vertical position of the fitting seat, that is, the vertical position of the valve body can be finely adjusted, and thereby the setting of the water stop level can be changed. After the adjustment, the fitting handle can be locked by lowering the adjustment handle and engaging the vertical grooves with each other again to lock the setting of the water stop level.

Since the adjusting handle is formed separately from the valve body, only one of them can be replaced, and the cost required for replacement can be kept low.

The same effect is obtained when the vertical groove formed on the retaining ring is formed on the upper edge of the inner peripheral surface of the case.

A link connecting the other end, the interlocking rod 34 is inserted into an insertion hole 33 opened in the lower portion of the valve body 7, and one end thereof is pivotally attached to the tip of a support portion 32 protruding from the lower portion of the body 1. Has been done. 36 is the water tank 26
A water supply port for supplying water, 37, ... is a caulking net, and 38 is a cap nut for fixing the caulking net 37 ,.

The ball tap constructed as described above is
It can be easily attached by closing the main tap of the water supply and screwing the intake port 2 into the water supply port (not shown) attached to the wall surface or the like of the building by screwing the cap nut 39. Initially, in the state where the float 28 is seated on the bottom of the water tank 26, the valve body 7 is located below the position shown in FIG. 1 and opens the valve port 23. Water is discharged from.

When the water level rises and the float 28 rises to the water stop position shown in FIG. 1, the valve body 7 as well as the packing 22 rises and the valve opening
23 is closed and water supply is stopped. In the water tank 26,
Although not shown, a siphon tube with an opening / closing lever is connected, and by operating the opening / closing lever, the water in the water tank 26 can be vigorously discharged to the toilet bowl. At that time, as the water level in the water storage tank 26 decreases, the float 28 moves downward, so that the valve body 7 begins to descend.

When the water level falls below a predetermined level, the valve port 23 is opened and water is supplied again from the water supply port 36 into the water tank 26, and when the water is supplied to a predetermined water stop level, the valve port 23 is opened again. Closed, water supply stops.

Since the above-mentioned water stop level is determined by the height position of the float 28 when the valve port 23 is closed by the valve body 7, the height position of the valve body 7 together with the fitting seat 6 is determined. If adjusted, the stoppage level setting can be changed. To do so, the adjustment handle 12 may be pulled up slightly and rotated to rotate the fitting sheet 6 together with the adjustment handle 12, and if the adjustment handle 12 is released at a desired position. ,spring
The adjusting handle 12 is pushed down by the resilience of 17 and the vertical groove 13 at the lower part thereof meshes with the vertical groove 11 of the retaining ring 8 to lock the set position. In this way, since the adjustment handle 12 is operated at a position above the water surface, the operability is extremely good, and since the set position is locked after the adjustment, the water stop level does not change thereafter. . In addition,
Needless to say, the water stop level can be finely adjusted by engaging the vertical grooves 11 and 13 with each other.

Further, since the valve body 7 is formed separately from the adjusting handle 12 and the retaining ring 8 described above, it can be replaced independently, and there is an advantage that the cost required for maintenance can be reduced.

The vertical groove 11 may be formed on the upper edge of the inner peripheral surface of the body without forming the vertical groove 11 on the retaining ring 8. In this case, the retaining ring 8 may function only to prevent the fitting sheet 6 from coming off.
