Description

Closed cleaning valve for water saving}

The present invention relates to a washing valve for supplying water to the toilet, in particular, the production cost is low due to the rigid valve structure, and a small amount of water is supplied when the push button is operated separately from the operation lever, water consumption is saved, It is related to water-saving toilet flushing valve which prevents the intrusion of foreign matter at the time of installation and there is no fear of failure and there is no fear of freezing in winter because it is not accumulated in water inside the valve.

In general, toilet stool cleaning is performed by flipping the operating lever exposed to the outside to open the valve to discharge a large amount of water. At this time, the inside of the valve is always filled with water supply, so there is room for breakage in winter. In addition, after urine in the toilet, only the operating lever to be operated, so much unnecessary water is used to waste water. Therefore, the valve of the toilet should be devised to save water by supplying only a small amount of washing water after urine and preventing freezing.

As a background technology of the present invention, the Korean Registered Room Registration No. 20-0293848, a water-saving toilet flush valve is proposed. The valve body has a flow path formed therein so that the washing water flows; An on / off valve installed at an outlet side of the flow passage inside the valve body; A water-saving toilet bowl cleaning valve having a pressing member installed on one side of the valve body and operating the opening / closing valve by an external operation, wherein the opening / closing valve is an opening / closing portion located at an outlet side of the flow path and the pressing member from the opening / closing portion. An eccentric protrusion projecting eccentrically to the side, and an actuating means provided at an end of the eccentric protrusion to open the outlet side of the flow path inclined when the pressing member is pressed, and restoring the opening and closing portion when the pressing member is restored. And restoring means for closing the outlet of the flow path.

In the background art, the urine push button is installed on the cover of the valve body so that the piston valve is inclined by about half as much as the stool by the vertical drop of the urine push button. After urine, press the urine push button, and only about half of the stool is discharged, so it is possible to select the amount of wash water discharged according to the stool.

However, the background art has a problem in that the valve structure is complicated to increase the manufacturing cost, and the water supply is always filled in the valve, so it is vulnerable to freezing. In addition, there is a disadvantage that the A / S is frequently generated because foreign matters enter the valve during construction to block the small passage.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other aspects of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings in which: FIG.

Water saving toilet cleaning valve according to this embodiment is provided with a pipe body 12 for discharging the water supplied from the water supply pipe 5 to the water discharge pipe 6 as shown in Figs.

The tubular body 12 has a piston packing operation cylindrical part 123 having a water supply inlet 121a and an opening / closing hole 121b at one end and an oil chamber 123a for storing oil at the other end. . At this time, the water supply inlet 121a and the water supply outlet 122 are formed at the lower side of the tube body 12. Therefore, the water flowed in from the water supply pipe 5 flows in the inverted U shape in the pipe body 12. The opening / closing hole 121b is formed with a diameter smaller than the internal passage of the tube body 12. It is preferable that a circular protrusion 127 is formed on the front surface of the opening / closing hole 121b in order to increase the tightness of the disk packing 208 of the valve unit 20 which will be described later. The opening / closing hole 121b opens and closes the passage of the tube body 12 by the disc packing 208 at a position close to the water supply inlet 121a. The tubular body 12 is preferably formed on the outer surface of the opening and closing hole (121b) side as shown in Figures 3a and 3b freeze-proof reinforcement rib (125). Therefore, when the opening / closing hole 121b is closed as shown in FIG. 1, even if the water filled in the water supply pipe 5 is frozen, freezing of the valve unit 20 side of the pipe body 12 can be prevented.

The lever holder 14 is attached to the cylindrical portion 123 for piston packing operation of the tube body 12. The lever holder 14 is screwed to the inner circumferential surface of the cylindrical portion 123 for piston packing operation through a thread formed on the outer circumferential surface.

The valve unit 20 is provided in the pipe body 12. The valve unit 20 closes the opening and closing hole 121b by the spring force, and opens and closes the opening and closing hole 121b by the operation lever 26 and the push button 28 which will be described later.

The valve unit 20 is located at the rear of the water supply inlet 121a and is screw-coupled to the spring support cap 202 and the spring support cap 202, which are screwed to the tubular body 12. Is adjusted to adjust the opening position of the maximum valve to adjust the water inflow amount of the water supply bolt 204, the disk support plate 206 is inserted into the water supply adjustment bolt 204 and the disk support plate 206 The disk packing 208 of rubber material which is in close contact with the front surface and opens and closes the opening and closing hole 121b, and one end is supported by the spring support cap 202 and the other end is supported by the disk support plate 206 to open and close the disk packing 208. It is comprised including the valve spring 209 which pushes by elastic force to the 121b side.

At this time, the quantity adjustment bolt 204 may be formed with a rectangular protrusion or groove that can be rotated by a tool such as a wrench or spanner. When the quantity adjustment bolt 204 is rotated and moved to the right side in FIG. 1, the maximum opening amount of the opening / closing hole 121b is reduced during the flipping operation of the operation lever 26. On the contrary, when the water control bolt 204 is moved to the left side and the operation lever 26 is flipped, the maximum opening amount of the opening / closing hole 121b is increased. Therefore, it is possible to control the amount of water passing through the opening and closing hole 121b with the water quantity adjusting bolt 204, it is possible to adjust the water pressure of the existing weak or strong place.

The moving rod 18 is attached to the lever holder 14. The moving rod 18 is movably inserted into the lever holder 14 and is connected to the valve unit 20 via the support 16. The support 16 is inserted into the tube body 12 so that one end is fitted to the disk support plate 206 and the other end is screwed to the moving rod 18. The moving rod 18 has a circular inclined surface 18a formed at the rear end to receive the manipulation force of the push button 28 to be described later.

The piston packing 22 is attached to the moving rod 18. The piston packing 22 is fixedly installed on the moving rod 18 to move integrally with the moving rod 18. The piston packing 22 is made of rubber, for example, is in close contact with the oil chamber 123a to slide and divides the oil chamber 123a into two areas ⓐ and ⓑ. The piston packing 22 has a large diameter hole 221 penetrated in the thickness direction.

As shown in FIGS. 1 and 4, the packing packing 24 is installed in the piston packing 22. The tight packing 24 is made of rubber or soft synthetic resin having flexible and elastic restoring force. The tight packing 24 has an orifice 241 of one end fixed to the piston packing 22 and a diameter smaller than the large diameter hole 221 at the other end. For example, the diameter of the orifice 241 may be formed to 0.5mm. At this time, the orifice 241 is installed in the piston packing 22 in close contact packing 24 so as to be located on the same axis as the large diameter hole (221). Therefore, when the piston packing 22 moves to the left as shown in FIG. 2, the oil in the area ⓐ of the oil chamber 123a moves to the ⓑ area, and if the piston packing 22 moves to the right, the oil chamber 123a The oil in area ⓑ of the vehicle moves to area ⓐ. At this time, since the oil in the region ⓑ passes through the small diameter orifice 241 when moving to the region ⓐ, the retraction speed of the movable rod 18 is lowered and the opening / closing hole 121b is gradually closed by the disk packing 208.

The operation lever 26 is supported by the lever holder 14. One end of the operation lever 26 is positioned inside the lever holder 14 to be in contact with one end surface of the moving rod 18, and the other end thereof is exposed to the outside so that the operation lever 26 can be flipped in any direction. Therefore, the opening and closing hole 121b is opened by retracting the disk packing 202 side of the valve unit 20 through the moving rod 18 and the support 16 during the flipping operation of the operation lever 26. Then, when the holding force of the operating lever 26 is removed, the disk packing 208 is moved by the valve spring 209 to block the opening / closing hole 121b, and the operating lever 26 returns to its original position.

The push button 28 is provided in the tube body 12. The push button 28 is provided on the upper part of the lever holder 14. The push button 28 is composed of a push pin 282, a button 281 screwed to the upper portion of the push pin 282. The push button 28 is push pin 282 is inserted into the tube body 12 is supported by the button spring 29 force, it is fixed by a button cap 27 screwed to the tube body 12. At this time, the lower end of the push pin 282 has a conical or inclined surface and its center is located on the inclined surface 18a of the moving rod 18 as shown in FIG.

Therefore, when the push button 28 is pushed down in the same state as in FIG. 1, the intrusion into the lever holder 14 as shown in FIG. 5 causes the inclined surface 18a of the moving rod 18 to be pressed. Therefore, the movable rod 18 is supported in the horizontal direction by the lever holder 14, and moves forward in proportion to the amount of pressing, and the opening and closing hole 121b is opened small by retreating the disk packing 208.

In this way, the opening amount of the opening / closing hole 121b according to the operation of the push button 28 is relatively smaller than the opening amount of the opening / closing hole 121b according to the operation of the operation lever 26. Can be discharged to (6).

On the other hand, the air hole 11a communicating with the oil chamber 123a is formed in the upper part of the tubular body 12, and the air hole 11a is further provided with the air hole stopper 30 which removes after installation of a washing valve. Is preferred. Therefore, the oil in the oil chamber 123a is blocked by the air hole plug 30 so that there is no fear of leakage during installation.

On the other hand, the water discharge pipe 6 connected to the water supply outlet 122 side of the pipe body 12 may appear in a bent form to adjust the installation position according to the pipe position during construction.

Reference numerals 3, 3a are 'couplings' and 301, 302, 303, 304 and 305 are 'watertight members'.

The operation of the present embodiment thus configured will be described.

<Valve closed>

First, when the operating lever 26 or the push button 28 is not operated, the disc packing 208 blocks the opening / closing hole 121b by the compression force of the valve spring 209 on the valve unit 20 side as shown in FIG. 1. It becomes the state that I do. Moreover, the piston packing 22 is located in the intermediate position of the oil chamber 123a, and the moving rod 18 will be in contact with the operation lever 26. As shown in FIG. In addition, the push button 28 is in the pressing standby state in the raised position by the button spring 29.

In this state, the water supply in the water supply pipe 5 is blocked by the disk packing 208, and the water supply is stopped. In addition, there is no fear of freezing of the valve in winter because the inside of the tubular body 12, that is, the opening / closing hole 121b and the water supply outlet 122 are empty and the water supply is empty.

< Operation lever  When operating

When the operation lever 26 is flipped as shown in FIG. 2, the movable rod 18 moves forward and the opening / closing hole 121b is opened by pushing the disc packing 208 of the valve unit 20 through the support 16. . At this time, the piston packing 22 moves together with the moving rod 18, and at this time, the oil in the area ⓐ of the oil chamber 123a easily moves to the area ⓑ through the large diameter hole 221. The packing packing 24 is heard at a flow rate passing through the large diameter hole 221, so that the operation of the movable rod 18 and the operation lever 26 is performed smoothly. Therefore, a large amount of water in the water supply pipe 5 flows into the wide gap between the disc packing 208 and the opening and closing hole 121b, passes through the opening and closing hole 121b, and is quickly discharged to the water supply outlet 122 to facilitate fecal washing. can do.

Then, when the holding force of the operating lever 26 is removed, the disk packing 208 is moved to its original position by the elastic force of the valve spring 209 to block the opening and closing hole 121b. At this time, the oil in the oil chamber 123a receives resistance through the orifice 241 of the tight packing 24, and the oil in the ⓑ region moves to the ⓐ region. Therefore, the retreat movement of the movable rod 18 is made gradually, and the speed of blocking the opening / closing hole 121b has a certain delay time and the discharge of the water supply is gradually stopped.

< Push button  When operating

When the push button 28 is pressed and operated as shown in FIG. 5, the moving rod 18 advances the valve spring 209 by the inclined surface 18a and advances the disk packing 208 via the support 16. The opening and closing hole 121b is opened by pushing. At this time, the distance for pushing the disk packing 208 is relatively smaller than the distance for moving the moving rod 18 forward to the operation lever 26 so that a small amount of water is passed through the opening and closing hole 121b and discharged to the water discharge pipe 6. As it is advantageous for washing urine, it is possible to wash water.

Then, when the pressing force of the push button 28 is removed, the piston packing 22 retreats gradually with the moving rod 18 in the same way as the pressing force of the operating lever 26 is removed, and the disc packing 208 opens and closes. Water supply is gradually stopped by closing the hole 121b.

As described above, according to the present invention, the water supply flow rate according to the operation of the push button 28 is discharged in a smaller amount than when the operation lever 26 is operated, and thus water saving effect may be observed when washing the urine.

In addition, since the air hole stopper 30 blocks the air chamber 11a side of the oil chamber 123a, foreign materials are blocked from being introduced into the oil chamber 123a during construction, thereby preventing malfunction.

In addition, when the valve is closed, the internal water supply of the tubular body 12 escapes to the water discharge pipe 6 and becomes empty so that there is no fear of freezing in winter. In addition, even if the water supply is filled by the water supply pipe 5 in the passage of the pipe body 12 in which the valve unit 20 is located, the reinforcement is made by the freeze protection reinforcement rib 125 so that there is no fear of freezing in winter.

Although the present invention has been described in detail with reference to the disclosed embodiments, those skilled in the art will be able to make various modifications and alterations without departing from the technical idea of the present invention will be. This invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
