Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a toilet tank outlet valve, and in particular to a float-free outlet that can be used for both drainage and overflow pipes in a toilet tank. Regarding valves,
The valve relates to a toilet tank outlet valve which can be opened in two stages and can be easily moved during repair or removal.

[Conventional technology and its problems]

Outlet valves traditionally used in flush toilet cisterns consist of an outlet valve, an overflow pipe, and a control float. Since such an outlet valve does not have a water saving mechanism, the duration of opening and closing of the float-controlled valve and the hole in the valve are always the same every time the toilet is flushed. Therefore, whether the toilet is used for defecating or urinating, the amount of water flowing down the drain is the same. In other words, water continues to flow until the tank is completely drained after one drain. This release of water sometimes results in great waste.

In general, water saving mechanisms have been developed using toilet tanks to achieve the purpose of water saving, and some types of products are already on the market. However, it is extremely inconvenient due to the need for additional equipment and the complete replacement of the inlet and outlet valves in the tank, as well as the complex assembly required and high cost in the production of this water-saving mechanism. There is.

Also, valves adapted to cover the metal valve seat in conventional outlet valves are simply rubber seat valves secured by a metal seat. After a number of uses, such rubber valves can easily wear out due to friction with metal, or the pulp outlet lip itself can become rusty and therefore uneven. In this way, the valve becomes less than perfect in terms of sealing, leading to leakage of the tank resulting in wastage of water. Such defects can be repaired by replacing the worn valve seat with a new one, but installation of a new valve seat can only be done with the aid of a tool, and different tools may be required. This can be said to indicate that it is generally inconvenient in daily life.

For pulp outlet edge rust, the only solution may be to replace it with a new outlet pipe connection.

Additionally, if a conventional outlet valve were to become useless due to a leaking or rupturing of the float, or if the flood pipe became rusty, it would be necessary to remove the entire piece and replace it with a new piece. Similarly, the replacement work requires the use of tools, which is also troublesome.

[Means for solving problems]

This invention improves the above-mentioned inconveniences in conventional outlet valves and provides a new outlet valve for flush toilets that has precise action, can be easily installed in the tank, and is effective in saving water. That is the purpose.

〔Example〕

In FIG. 1, an outlet valve A according to the invention is shown installed in a tank B of a flush toilet adapted for use with an actuating lever C and a drain handle D, as in the prior art. Also shown in the figure is the inlet valve E.

As shown in FIG. 2, the outlet valve A of the present invention includes a valve body 1. 2. A valve part that is pivoted around the lower part of the valve body 1 and opens and closes the outlet of the valve. It includes a control body 3 which is pivoted about the lower part of the valve body 1 and is located at the rear of the valve part.

The pulp body 1 is closed at the top 1!11 and has a vertically placed overflow pipe 13 having an overflow port 12 on one side of the upper end.
and a valve seat 1, which is located at the lower end of the overflow pipe 13 that extends to one side and is located at the end of the slightly L-shaped part with the drain pipe 13, and is also provided with a valve outlet 14.
Consists of 5. The outlet 14 of this valve seat 15 is connected by a connecting pipe 16 and a water channel 17 to an outlet 10 at the end of the overflow pipe 13. The upper end of the valve outlet 14 of the valve seat 15 is slightly inclined, but the lower end is kept horizontal, and the peripheral wall 18 at this lower end has a plurality of fixing grooves 19 which are connected to the above-mentioned outlet pipe fitting 4 by turning. It is formed by.

The pulp part 2 has a supporting part 20 having a front part consisting of a curved plate-like wire-like disk 21 and a rear part consisting of a U-shaped arm 22 that tilts and extends backwards and upwards, and a supporting part 20 that has a structure around it. When viewed in cross-section, the valve 26 is firmly connected to the flange 24 of the disk 21 by a U-shaped flange 23 and has a hole 25 in the center. This valve 26 seals the valve outlet 14 of the valve seat H5 by means of a sealing flange 27 located below the flange 23 mentioned above (see FIG. 5). Further, as shown in FIG. 4, there is a U-shaped arm 22 connected to the disc 21, which is provided with a stopper 28 and two shafts 29 that protrude slightly rearward and inward. By inserting these two protruding shafts 29 into two holes made on both sides of the lower part of the overflow pipe 13, the valve part 2 is
It can rotate around the shaft 29. Next, a chain or rope belt 5 is connected to the front end of the disc 21, and the other end is connected to an operating lever C.

The control part 3 of the outlet valve then consists of a somewhat cap-shaped cavity 31 which is closed on the upper side and completely open on the lower side. This hollow body 31 has a front wall 32 and two side walls 30, and the Y-shaped side wall 30 extends from a curved rear wall 33 to the front of the front wall 32. In the center of the front wall 32 there is a protruding bar 34 extending upward, and at the bottom there are two protruding arms 36.
Each has a fulcrum pin 35 on its inner wall. The fulcrum pins 35 of these protruding arms 36 are respectively engaged in holes 132 of a protruding handle 131 made in the rear wall of the lower part of the overflow pipe 13, and the control body 3 is vertically rotated using the pins 35 as fulcrums. can do.

The outlet valve of the toilet tank is normally held open with the rear part of the U-shaped arm 22 touching the upper end of the protruding bar 34, and the gas sac pulp 26 sealing the pulp outlet 14 by the flange 27. do.

According to the design that the outlet valve A of the present invention can be installed and removed in a short time, there is a backing 42 in the annular groove 41 of the peripheral wall at the upper end, and the peripheral wall located below the backing 42 has the above-mentioned The outlet pipe fitting 4 with the fixing projection 43 connected to the fixing groove 19 and the bottom of the toilet tank B must be compatible. When the fixing groove 19 is moved into connection with the fixing projection 43 by simply turning the outlet valve A, this fixing pulp A is joined to the outlet pipe fitting 4 in a waterproof manner by means of the backing 42 . To remove outlet valve A, simply turn the valve in the opposite direction. The outlet pipe fitting 4 furthermore has a flange 44 in its center, under which there is a toilet tank sealing washer 45, under which the outlet pipe fitting 4 is placed on the toilet tank B. There is a nut 46 for installation, and at the bottom of the accessory there is also a nut 47 for attaching the outlet pipe 6. In fact, except for the aforementioned backing 42 and fixed protrusion 43 that the outlet pipe fitting 4 has at its upper end, the joint between the toilet tank and the outlet pipe fitting and the outlet pipe and the outlet pipe fitting are different from each other. For the rest of the structure, any conventional pipe fittings or other types of construction can be used in the present invention, provided that the joints are waterproof.

With the above-described construction in this invention, once the toilet tank is permanently connected to said pipe fitting 4, the outlet valve A is installed and integrated with the fitting 4 by screwing it into place. The installation of the outlet valve A of the present invention is very convenient in the hour wheel, since no tools are required for this operation. Furthermore, when the user needs to release a small amount of water during draining in order to save water, he can do so by operating the two-stage drain handle D and lifting the chain 5 somewhat upward through the operating lever. can be executed. In this way, the valve 26 is in contact with the pulp beneath it with the arrangement of the switch such that the end of the arm 22 is still in contact with the protruding bar 34 of the control body 3, as indicated by the dotted line in FIG. When lifted around the shaft 29 to open the outlet 14, the opening of the valve outlet is relatively small and therefore the amount of water discharged is small. Further, when the hand holding the switch is released, the valve 26 closes the outlet under its own weight and returns to the state shown in FIG. 2 again. However, when the second position of the drain handle D raises the chain 5 and moves downward until the end of the arm 22 is in the recess in the lower part of the projecting bar 34 via the shaft 29, the control body 3
As a result of the buoyancy of the water flowing into the central cavity of the arm 2 and the self-correction of the center of gravity, the control body 3 rotates counterclockwise via the fulcrum pin 35, so that the lower end of the protruding bar 34 moves toward the arm 2.
It will be fixed at the end of valve 2, thereby
is held in the fully open position. Therefore, the valve 2 will discharge water until the water level drops to the point where the amount of water inside the central cavity of the control body 3 and the buoyancy force cannot balance the gravity of the valve 2 even if the hand is released from the switch arrangement. When the water level drops, the valve closes automatically.Thus, a person going to the toilet on demand can automatically drain more water from the tank by keeping the chain up, or It can also be desired to discharge an appropriate amount of water corresponding to the time he presses the discharge handle, thus achieving the purpose of water saving according to the requirements of the person using the toilet.Control body When the amount of water in 3 decreases and the water level falls to the point where the force of the water is no longer sufficient to balance the gravitational force on valve 2, valve 2 lowers, closing valve outlet 14 and also simultaneously shown in FIG. The control body 3 returns to the state as before.

Due to the gas volume type that forms the valve 26 and the presence of the double flanges 23 and 24 in the opening and closing action of the valve 2, the valve 26 has flexibility and cushioning effects, so that it can fit properly into the valve outlet. automatically keep yourself in the shape you want. The valve seat 15 is made of plastic, which can be kept smooth and rust-free, and the valve outlet 14 with high precision, thereby increasing the durability in use of the valve and at the same time ensuring the sealing of the valve outlet 14. Can be done. Furthermore, since the overflow pipe 13 is completely closed at the upper end, there is no risk of other substances entering the pipe directly and causing disturbances therein. In addition, with the exception of chain 5, which is made of stainless steel, all remaining parts are made of acid-alkali and chemically resistant plastics and synthetic rubbers, which help prevent oxidation and corrosion of the parts. , thereby extending the life of use. If the valve 26 is unexpectedly destroyed and can no longer be sealed, all you need to do is remove the valve and install a new one, but no tools are required to do so. However, it is very easy to install it by yourself. In particular, if there is a failure in the entire valve unit (though the possibility of this is of course very small), it can be easily removed by simply turning the central valve body 1 slightly relative to the accessory 4. The repaired valve unit or the new unit can be easily installed by turning it in a similar manner, without the need for a plumber or the use of special tools. Therefore, the present invention is practically convenient to use.

Although the invention has been described with respect to preferred embodiments, various changes and modifications can be made in the art without departing from the scope of the invention.

〔Effect of the invention〕

The outlet valve of the present invention is convenient to assemble and remove by simply moving the valve body in the positive or negative direction relative to the accessory without using any tools. Furthermore, the outlet valve of the present invention does not require any accessories such as a float or a float spatula, and the overall structure is simple and compact, which saves time and space when installed in a tank. Further, the outlet valve of the present invention can drain all or part of the water in the tank according to the user's request by connecting the cap-shaped control body to the arm, which is effective in saving water. Additionally, the overflow pipe of the outlet valve of the present invention has its outlet open near the water surface to prevent outside debris from entering the pipe and causing obstruction. Further, by using an expanded rubber valve body, the disadvantage of leakage caused by incomplete sealing can be eliminated, and water wastage due to leakage can be prevented.
