BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid on / off valve for use in a large toilet, and more particularly to an improved fluid on / off valve for operating a button installed to flow or block a fluid with less force than in the prior art.

1 and 2 are internal cross-sectional views showing the operating state of the fluid valve for urinals according to the prior art.

1 and 2 as the fluid on-off valve 100 is installed to discharge the water in the urinals in response to the user pressing the button 120, it is known in the Republic of Korea Utility Model Publication No. 1990-0000061, In general, it consists of:

The fluid opening and closing valve 100 of the prior art is formed in the inlet 111 is protruded on the side of the valve body 110 such that the inlet 111 is connected to the fluid inlet pipe, the outlet 112 in the lower portion of the valve body 110 ) Is formed to protrude.

In addition, the fluid open / close valve 100 has a flow passage of the fluid formed inside the valve body 110, and the fluid introduced through the inlet 111 exits downward through the outlet 112. At this time, the piston body 140 is installed on the valve body 110, the upper portion of the fluid outlet 112, and moves up and down according to the operation of the button 120. In addition, the through-hole is formed on the inner axis of the piston member 140, the fluid opening and closing valve 100, the T-shaped piston rod 150 located in the through-hole blocks the through-hole. In addition, the fluid opening and closing valve 100 is coupled to the side of the valve body 110 so that the button 120 is pulled from the button 120 to the end of the piston rod 150 abuts.

Due to such a configuration, when the user presses the button 120 in the horizontal direction, the fluid on-off valve 100 of the prior art, while the rod connected to the button 120 pushes the end of the piston rod 150, the piston rod ( The top of 150 will be heard. Then, the fluid opening and closing valve 100 is dropped to the lower portion while the fluid in the hydraulic chamber 160 located on the upper portion of the piston member 140 little by little. Then, the fluid opening and closing valve 100 lowers the pressure in the hydraulic chamber 160 due to the outflow of the fluid, the piston member 140 is moved to the upper side. Thus, the fluid on-off valve 100 opens the fluid flow path by the action of the piston member 140, while the fluid in the fluid inlet chamber 170 located on the inlet 111 side flows, through the outlet 112 It will exit to the bottom.

As described above, the fluid open / close valve 100 of the prior art should lift the upper portion of the piston rod 150 to discharge the fluid, but the piston rod 150 is closely contacted by the pressure of the hydraulic chamber 160 filled with the fluid. Because of this, the button 120 must be pressed with a certain force.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the fluid discharge valve of the present invention will be described in detail.

3 and 4 are internal sectional views showing an operating state diagram of a fluid on / off valve used in a toilet in accordance with an embodiment of the present invention, and FIG. 5 is a flow and shutoff of fluid in the fluid on / off valve shown in FIG. 4. An enlarged cross-sectional view of a fluid opening and closing means for manipulating the device.

3 to 5, the fluid on-off valve 200 of the present invention is installed in the device for discharging the fluid as needed, such as a urinal or toilet. That is, the fluid on-off valve 200 of the present invention further forms a pressure discharge chamber 284 as a second partition wall 280 in the space of the fluid pressure chamber 260 located above the piston member 240, and the button By the opening and closing means 290 connected to the 220, the fluid in the fluid pressure chamber 260 is discharged to the pressure discharge chamber 284, the piston member 240 is behaving to the top, the inflow through the inlet 211 The discharged fluid is discharged to the outlet 212 along the flow passage. As described above, the fluid on / off valve 200 of the present invention is operated with the opening and closing means connected to the button 220 with much less force than the force pushing the piston rod in the prior art, and it is easy for the elderly or children as well as anyone with little force. Available.

Looking at each component and the coupling relationship of the fluid on-off valve 200 of the present invention, as follows.

The fluid on / off valve 200 has a valve body 210 having an inlet 211 and an outlet 212. The valve body 210 may be manufactured in various shapes as needed, but as is generally used, the inlet 211 is formed to protrude to the side, the outlet 212 is formed to protrude downward, and the inside As a result, a fluid flow path is formed. In addition, the valve body 210 has a first partition wall 214 formed inside the point where the water outlet 211 is bent to the lower portion of the water outlet 212. The first partition wall 214 of the valve body 210 is installed to control the movement of the fluid, the piston member 240 is fitted into the flow hole of the inner center. Then, in the present invention, as the piston member 240 moves up and down according to the operation of the button 220, the flow hole formed in the first partition wall 214 is opened, and the fluid may be discharged to the water outlet 212. .

The upper side of the piston member 240 is in contact with the inner wall of the valve body 210, the lower portion is fitted to the first partition wall 214. Due to the installation of the piston member 240, the fluid opening and closing valve 200, the fluid inlet chamber 270 and the fluid located in the upper portion of the piston member 240 on the inlet 211 side inside the valve body 210 Pressure chambers 260 are formed respectively. However, the first flow path 245 having a relatively small diameter is formed in the piston member 240. Accordingly, in the present invention, while the fluid in the fluid inlet chamber 270 flows into the fluid pressure chamber 260, the fluid pressure chamber 260 is filled with the fluid. In addition, a through hole is formed in the piston member 240 along an inner axis thereof, and the first packing member 241 is fitted to the lower outer circumference so that fluid is not lost in the gap between the first partition walls 214. .

The fluid discharge member 250 is installed in the inner through hole of the piston member 240 in an elongated tube shape, so that even if the piston member 240 moves up and down, only the surface contact with the piston member 240 is mutual. In addition, the fluid discharge member 250 has a fluid discharge path 251 formed therein, and an upper portion thereof is threaded to the second partition wall 280.

The second partition wall body 280 is positioned above the piston member 240 and is coupled to the inside of the valve body 210. As such, the second partition wall body 280 is installed, so that the fluid opening / closing valve 200 of the present invention has a separate pressure discharge chamber 284 formed between the inside of the valve body 210 and the second partition wall body 280. do. As described above, the fluid discharge member 250 is coupled to the second partition wall 280 so that the fluid discharge path 251 and the pressure discharge chamber 284 of the fluid discharge member 250 communicate with each other. As a result, the pressure discharge chamber 284 is filled with air introduced through the water outlet 212 and the fluid discharge path 251. In addition, the opening and closing means 290 of the fluid is installed in the second partition wall body 280.

The opening and closing means 290 includes a connecting rod 291, an O-ring 292, an elastic body 293, a support 294, and a second packing member 295.

The connecting rod 291 is formed on the second partition wall 280 and is fitted into the second flow path 285 formed slightly larger than the connecting rod 291. 280). The other end of the connecting rod 291 passes through the valve body 210 to be in contact with the button 220.

The O-ring 292 is fitted to one end of the connecting rod 291 to seal the fluid so as not to flow into the gap between the connecting rod 291 and the second flow path 285.

The elastic body 293 is located in the pressure discharge chamber 284 as a coil spring and fitted to the outer circumference of the connecting rod 291 to provide an elastic force.

The support 294 is fixed at one point in the longitudinal direction of the connecting rod 291, and is installed to limit the movement of the elastic body 293.

In addition, in the present invention, since the other end of the connecting rod 291 penetrates through the valve body 210, a minute gap exists between the connecting rod 291 and the valve body 210. The opening and closing means 290 of the present invention is flexible in accordance with the vertical movement of the connecting rod 291 while sealing the inside of the pressure discharge chamber 284 so that the fluid filled in the pressure discharge chamber 284 does not escape by such a gap. And a second packing member 295 that interlocks with each other. To this end, the edge portion of the second packing member 295 is integrally fixed to the valve body 210, and the connection rod 291 is fitted at the center thereof.

And, the fluid on-off valve 200 of the present invention is installed so that the button 220 is exposed to the outside on the upper portion of the valve body 210, the end of the connecting rod 291 is connected to the lower portion of the button 220, The connection rod 291 is actuated by pressing the button 220.

Hereinafter will be described the operating relationship of the fluid on-off valve 200 according to the present invention.

The fluid on / off valve 200 of the present invention is configured to discharge a fluid such as water according to a user's operation, and is generally used to install a urinal, and may be applied to a toilet as shown in FIG. 6.

The fluid on / off valve 200 shown in FIG. 3 is a normal internal cross-sectional view which does not discharge fluid, and the fluid flows through the inlet 211 and the first flow path 245, and the fluid inlet chamber 270 and the fluid pressure. Each of the chambers 260 is completely filled with fluid.

Then, when the user presses the button 220 located on the upper portion of the fluid on-off valve 200 after finishing the toilet, each component of the fluid on-off valve 200 is operated as follows.

That is, in the present invention, while the button 220 is pressed downward by the user, the connection rod 291 connected to the lower portion of the button 220 is interlocked. Then, the opening / closing means 290 descends the connecting rod 291, which has sealed the second flow path 285, and the fluid filled in the fluid pressure chamber 260 through the second flow path 285 is discharged from the pressure discharge chamber. After exiting 284, it exits to the outlet 212 through the fluid discharge path 251. At this time, since the flow cross-sectional area of the second flow path 285 is wider than that of the first flow path 245, which is a passage between the fluid pressure chamber 260 and the fluid inflow chamber 270, the fluid in the fluid pressure chamber 260 has an outflow amount. More than the inflow, the pressure in the fluid pressure chamber 260 is gradually lowered.

That is, the upper pressure of the piston member 240 is lower than the lower pressure of the piston member 240, so that the piston member 240 gradually moves upward, and the flow hole of the first partition wall 214, which has been sealed, is little by little. Open. Then, the fluid of the fluid inlet chamber 270 rapidly exits through the flow hole of the first partition wall 214 as the pressure is released, and is discharged to the outside through the outlet port 212.

Then, when the user raises his hand from the button 220, the elastic body 293 of the opening and closing means 290, which has been compressed, pushes the support 294 upward and the connecting rod 291 coupled with the support 294. ) Rises to the top. Then, in the fluid on-off valve 200 of the present invention, one end of the connecting rod 291 blocks the second flow path 285, and the fluid in the fluid pressure chamber 260 can no longer be moved to the pressure discharge chamber 284. .

In this state, the fluid on / off valve 200 of the present invention has a higher pressure on the lower side of the piston member 240 than the fluid pressure chamber 260 because the fluid rapidly exits to the flow hole of the first partition wall 214. Increases. Therefore, while the fluid in the fluid inlet chamber 270 flows into the fluid pressure chamber 260 through the first flow path 245, the piston member 240 gradually moves downward. In addition, according to the present invention, the piston member 240 completely closes the flow hole of the first partition wall 214 so that the fluid is no longer discharged through the outlet port 212.

As described in detail above, the fluid open / close valve of the present invention discharges the fluid in the fluid pressure chamber by using the open / close means to discharge or shut off the fluid with relatively less force than the prior art, which had to press a button above the internal pressure of the fluid pressure chamber. There are advantages to it.

In addition, the fluid on-off valve of the present invention has the advantage that the user can easily discharge the desired amount of fluid for a desired time because the button operation with less force than the prior art.

The technical idea of the fluid on / off valve of the present invention has been described above with the accompanying drawings, but this is only illustrative of the best embodiment of the present invention and is not intended to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
