It includes a guider (10c).

A pressure chamber 13 is formed at the upper end of the outlet pipe 12b so that a valve 20 for opening and closing the outlet pipe 12b is assembled, and a cap 14 is detachably attached at the upper end of the pressure chamber 13. It is assembled.

In the pressure chamber 13, a valve fixing groove 13a is formed in a circular shape in which the edge portion of the valve 20 is seated and fixed, and the edge of the valve 20 is fitted into the groove 13a. do. The valve 20 has an extension tube located on the bottom surface of the cap 14 so as to be positioned above the groove 13a, and the valve 20 provides a sealing effect between the water channel and the pressure chamber 13.

In addition, the cap 14 has a key groove 14a formed on the circumferential surface thereof so as to be assembled and disassembled with the housing side key 10d formed around the pressure chamber 13, and pivotable on the upper side thereof. The pressing lever 40 supporting the shaft to be coupled is coupled. In addition, a pressure release pin 41 is provided for maintaining or releasing the pressure in the pressure chamber 13.

As shown in FIG. 6, the pressure release pin 41 has a spring 15 installed therein so that its end protrudes from the bottom of the pressure lever 40 and is provided by a rubber O-ring 16. The hole 14b provided with the pressure release pin 41 is blocked.

The valve 20 is installed in the pressure chamber 13 to open and close the water outlet pipe 12b as shown in FIG. 5, and is made of soft rubber material, and the edge portion of the valve 20 is formed in the groove of the pressure chamber 13. 13a), and the inner surface adjacent thereto has a circular tension portion 22 that is thinner than other portions and has flexibility. The tension section 22 will be described in more detail in the following operation, but the center 24 for guiding the valve 20 to be moved up and down by the hydraulic pressure and positioned correctly on the inlet of the outlet pipe 12b. ) Is installed. In addition, a relatively small channel hole 25 is formed on the surface of the valve 20. The channel hole 25 enters the water outlet tube 12b by making a U-turn of water introduced into the inlet tube 12a. Allow water to flow into the pressure chamber 13 before.

The sub-ball 30 is manufactured in a shape having an open bottom portion, and includes a rib 30a (see Fig. 3) extending in a predetermined length at a central portion thereof and a small air hole 30b in the circumferential surface thereof. The float 30 is supported on the housing by a float support 31 coupled into the rib 30a, and the float support 31 is slidable to the guider 10c attached to the side of the water guide tube housing. To be assembled. In addition, the buoyancy support 31 is formed with the ribs on the unevenness 31a by forming an unevenness 31a on the buckle support 31 so that the height of the buckle 30 can be adjusted in being assembled with the buckle 30. The protrusions installed inside are caught and fixed. Therefore, the water level can be adjusted according to the assembly position of the floats.

Referring to the operation of the valve assembly for water level control in the present invention configured as described as follows.

First, the process of introducing water into the toilet is described.

As shown in FIGS. 3 to 6, when water having a predetermined water pressure is introduced through the inlet pipe 12a, the water is introduced into the pressure chamber 13 through a small hole formed in the surface of the valve 20, thereby providing a constant pressure. Hydraulic pressure is inherent in the seal 13. By this water pressure, the valve 20 is pressurized downward so that the water outlet pipe 12b may be blocked.

Therefore, when water begins to be filled into the toilet bowl, the water level rises and the water begins to fill into the mouthpiece 30. At this time, in the buoy 30, the air is leaked out of the air hole 30b while the water is filled therein, and when the water is filled above the height of the air hole 30b, the buoy 30 floats on the water by buoyancy. Therefore, as the float 30 rises, the pressure lever 40 interlocking with the float support 31 rotates about the pivot axis to release the end of the pressurized pressure release pin 41.

Therefore, the pressure release pin 41 moves upward by the spring 15 therein and blocks the hole 14b of the cap 14 to which the pressure release pin 41 is coupled by the rubber o-ring 16 to press the pressure. The seal 13 is maintained to maintain a constant water pressure. The water pressure in the pressure chamber 13 is generated by the water pressure of the water flowing through the water inlet pipe 12a and the waterway hole 25. In this way, a predetermined water pressure is built in the pressure chamber 13, and the valve 20 closes the upper end of the water outlet pipe 12b by the water pressure so that water does not enter the toilet water tank.

First, as shown in FIGS. 2 and 7 when the operating lever (L) installed on the outside of the toilet water tank is rotated, the drain opening (H) is installed on the bottom of the toilet water tank open while the water rests through the drain hole (H) Will be discharged into the stomach. At this time, when the water filled in the toilet water tank (T) is discharged, the water level is lowered and floated on the water float 30 is lowered by its own weight.

At this time, the water level is rapidly lowered as the water is discharged to the drain (H), but the water filled in the float 30, that is, the upper side of the small hole (30b) of the float 30 is air into the hole (30b) The water falls into the bottom as it is introduced, but because the size of the hole (30b) is small because the air does not rapidly enter into the floats 30, the speed of the outside water is made faster than the rate of water in the floats (30) down. As a result, the water contained in the float 30 is discharged later than the discharge rate of the water in the toilet tank T, so that the weight of the float 30 is greater than its own weight by the water contained in the float 30. Increasing the weight of the float 30 is to press the pressure lever 40 downward while the float support 31 is lowered to more strongly press the end of the pressure release pin 41.

When the pressure release pin 41 is pressed, the rubber o-ring 16 coupled to the shaft of the pressure release pin 41 opens the hole 14b of the cap 14 to which the pressure release pin 41 is coupled as shown in FIG. 8. The water contained in the pressure chamber 13 is discharged therebetween. At this time, the water in the pressure chamber 13 is lifted up by the valve 20 by the water pressure flowing into the water inlet pipe so that the water in the pressure chamber 13 is discharged to the outside.

Therefore, when the sub-ball 30 is sufficiently lowered, the pressure release pin 41 is pressed by the pressure lever 40, whereby the pressure in the pressure chamber 13 is lower than the water pressure flowing into the inlet pipe 12a and the valve 20. ) Is lifted up by the water pressure so that the outlet pipe 12b and the inlet pipe 12a pass through each other and the water is introduced into the toilet tank T to be filled.

As described above, the water level control valve for a toilet according to the present invention provides an improved water level control valve for a toilet that improves durability and facilitates assembly by having a simple structure of an inlet pipe, a supporter, and a water channel opening / closing valve. can do.
