Description

Autistic turn-off valve

The present invention relates to a self-closing valve and more particularly to a self-closing valve for closing the flow path automatically after a predetermined time after opening the flow path by pressing the operating port.

Furthermore, the present invention relates to a self-closing valve which is easy to operate by making the valve open time by the hydraulic pressure of the fluid flowing into the water pipe, and the overall configuration is simple.

In addition, the present invention relates to a self-closing valve that is easy to install by separating only the valve installed in the existing water facility or shower facility and to be installed in the valve connection.

Due to climate change around the world, precipitation is decreasing day by day, and desertification is progressing rapidly.

Due to such water shortages, it is frequently appearing in Korea, and in order to prepare for such a phenomenon, many policies are being implemented to protect water resources and prevent waste.

As one of these measures, the installation of water-saving devices for the construction of buildings is made into law.

One such water-saving device has been developed and used to open and close the valve to reduce the amount of water discharged by allowing the user to easily open and close the water supplied to the tap or shower.

Such a valve is developed and used as the opening and closing valve when the operating opening is pressed and the operating opening is released, but this is inconvenient to use because the water is discharged only when the operating opening is pressed by hand. The valve opening and closing means can be installed so that the user can operate the opening and closing means by a foot or body other than a hand, allowing the user's hands to freely while using water, and freely by separating the foot or body from the valve at the same time as the use is finished. There is a structure that can reduce the time that water is extracted by not having to lock the valve by the used hand, but it is complicated to configure the opening and closing means separately from the valve, and the opening and closing means is easy to manage the opening and closing means installed apart from the valve. Did not do it.

In addition, a valve for automatically closing the flow path after opening the flow path only for a predetermined time when the operation button is pressed has been developed and used. However, the conventional self-closing valve is completely separated from the existing faucet or sour installing means. Since the water pipes should be cut and installed, there was a need to cut and install the installed water pipes, or to reinstall the water supply facilities.

The present invention has been made to solve the above problems, it is easy to operate by opening and closing by the hydraulic pressure of the fluid supplied from the water supply pipe, the configuration is simple to provide a self-closing valve that is easy to manufacture, construction and management. The purpose.

In addition, the present invention aims to provide a self-closing valve that can be easily installed by removing only the on-off valve from the existing water supply facility.

Circular packings 10a, 10b, 30a, 30b, 40b, 50a, and 80a are respectively provided on the surfaces where the parts face each other.

Hereinafter will be described with reference to the accompanying drawings the operation of the self closing valve according to the present invention configured as described above.

Figure 3a and 3b is a cross-sectional view for explaining the process of opening the self-closing valve according to the present invention, Figures 4a and 4b is a cross-sectional view for explaining the process of closing the self-closing valve according to the present invention, Figure 5 is the present invention Is a side view of a state in which a self-closing valve is installed in a shower.

First, in the state in which the valve is closed, as shown in FIG. 2, a flow path between the outer circumferential surface of the auxiliary piston 40 and the inner circumferential surface of the small diameter portion 31 of the piston guide 30 is blocked by the packing 30b.

As shown in FIG. 3A, when the actuator 60 is opened to open the valve, the end of the adjustment bolt 80 presses the bolt head of the fixing bolt 70, and when the fixing bolt 70 is pressed, the auxiliary piston 40 is pressed. Is moved down.

When the auxiliary piston 40 moves, the circular packing 30b provided on the outer circumferential surface of the auxiliary piston 40 moves away from the small diameter portion 31 of the piston guide 30 and is disposed between the outer circumferential surface of the auxiliary piston 40 and the small diameter portion 31. The flow path is opened.

When the flow path is opened as described above, the fluid is formed along the flow path 11 formed on the side wall of the opening / closing housing 10 and the partition formed at the end of the pressurizing piece 27 formed at the top of the opening / closing piston 20 and the opening / closing housing 10. Some of the fluid flowing into the space between the (13) and moving to the water supply pipe is formed in the center of the opening and closing piston 20, the flow paths 22 and 21-the through hole 34a of the spring support plate 34-the auxiliary piston ( Partition wall 13 formed at the middle of the pressurizing piece 27 and the opening / closing housing 10 through a path of the passage 11 formed long on the sidewall of the opening-closing housing 10 between the outer circumferential surface of the 40 and the small diameter portion 31. ) Between the pressurizing piece 27 and the partition 13 formed at the interruption of the opening and closing housing 10 directly through the partition flow path 12 formed at the partition 13 of the interruption of the opening and closing housing 10 while being moved to the space therebetween. Flows into space.

A portion of the fluid also moves along the flow path 42 formed in the auxiliary piston 40 to the space between the pressing plate portion 41 of the auxiliary piston 40 and the partition wall 51 of the auxiliary housing 50.

Accordingly, the opening and closing piston 20 moves to the operation port 60 side, so that the opening and closing packing 24 at the end of the opening and closing piston 20 opens the flow path.

That is, as shown in FIG. 3B, the flow path of the water conduit is opened.

Pressing the operation tool 60 once maintains the pressed state by the pressure of the fluid introduced into the space between the pressing piece 27 and the partition 13 formed in the middle of the opening and closing housing 10 as described above, When the fluid is discharged to the discharge port according to the opening of the fluid, the hydraulic pressure inside the self-closing machine is lowered according to the speed of the discharged fluid, and at the same time, it is formed at the stop of the pressing piece 27 and the opening / closing housing 10 by the hydraulic difference between the spaces. The fluid stored in the space between the partitions 13 is discharged in the reverse order as described above.

Accordingly, the space between the pressing piece 27 and the partition 13 formed at the middle of the opening / closing housing 10 is emptied and the pressure is reduced so that the opening and closing piston 20 moves toward the water supply pipe to block the flow path.

At this time, the fluid filled in the space between the pressure plate portion 41 of the auxiliary piston 40 and the blade 35 of the piston guide 30 is passed through the plate through-hole 41a formed in the pressure plate portion 41 of the auxiliary piston 40. The space between the pressure plate portion 41 of the auxiliary piston 40 and the blade 35 of the piston guide 30 is filled.

The movement distance of the opening and closing piston 20, that is, the degree of opening and closing of the water conduit flow path may be adjusted by tightening or releasing the adjusting bolt 80.

The self-closing valve according to the present invention, which is constructed and operated as described above, is easy to install because the installation is completed by removing only the existing valve and tightening the valve inserting part, and opening and closing by the pressure of the fluid flowing from the water supply pipe. This is done by the adjustment of the opening and closing amount adjustment bolt can adjust the opening and closing amount according to the hydraulic, it is easy to install and manage as well as the production is not provided with a separate opening and closing means.

In addition, once the operating port is pressed once, the flow path is opened for a predetermined time and automatically closes to free the hand, thereby facilitating washing or other manual work.
