Description

Water control valve {CONTROLLING WATER VALVE}

The present invention relates to a water control valve, and in particular, to provide a structure capable of closing the water control valve in a push manner.

The most representative of the various water control switchgear currently on the market is the infrared sensing valve. When the user puts his hand in the proper position during the cleaning operation, the water valve is opened by the detection of infrared rays and water is supplied through the faucet. However, such a water valve also has a disadvantage, if the water supply time is limited to some extent, if the user can not complete the cleaning operation within that time, the detection operation had to proceed again. In addition, since the sensitivity of the infrared detection is not high, infrared detection is possible only when the user places his hand in a specific detection area. It is a conventional water control valve developed to solve this inconvenience.

6 and 7, the conventional water control valve includes an outer housing 50, a control valve system 60 and a position stator 70. As shown in FIG.

The upper concave groove 51 is formed in the upper end of the outer housing 50 in a stepped shape, the through hole 52 is formed in the lower end of the upper concave groove 51, the lower end of the outer housing 50 The lower concave groove 53 is formed in a stepped shape, the upper concave groove 51 and the lower concave groove 53 forms a state in communication with each other through the through hole (52).

The control valve system 60 includes a valve spindle 61, a valve seat 62, a push rod 63 and a support rod 64.

The valve spindle 61 has a conical closed end 611, and the closed end 611 is installed inside the upper concave groove 51, and an extension rod 612 at the bottom of the closed end 611. The extension rod 612 extends into the lower concave groove 53 through the through hole 52, and the outer sidewall of the extension rod 612 is spaced apart from each other and protrudes. The side wing 613 is formed.

The valve seat 62 is provided inside the lower concave groove 53, the edge portion of the valve seat 62 meshes with the inner edge portion of the lower concave groove 53, and the valve seat 62 has an extension rod ( A perforation 621 is formed through which 612 can pass. An angle pin 622 having a saw blade shape is formed on the inner wall of the perforation 621, and a guide groove 623 is formed between the two angle pins 622. In addition, the valve seat 62 is formed with a plurality of flow holes 624 spaced apart from each other at regular intervals in a position adjacent to the perforation 621.

An accommodating groove 631 through which the extension rod 612 penetrates is formed in the push rod 63, and a plurality of push blades 632 spaced apart from each other and protruded on the outer wall of the upper end of the push rod 63. Is formed.

A push groove 641 is formed at an upper end of the support rod 64 to accommodate the bottom of the push rod 63, and an angle pin 642 having a saw blade shape is formed at an upper end of the support rod 64. In addition, a plurality of protruding guide blocks 643 are formed on the outer side wall of the same side end portion and can slide in the guide groove 623. The bottom of the support rod 64 also extends outward through the perforations 621 of the valve seat 62.

The position stator 70 is fixedly installed in the lower concave groove 53, and the position stator 70 is provided with a fixing hole 71 that is engaged with the bottom end of the valve seat 62 and the control valve system 60. ) Is installed inside the outer housing 50. The position stator 70 is also provided with a plurality of passing holes 72 spaced apart from each other at a position adjacent to the fixing hole 71.

In practical use, a conventional water control valve is connected to the faucet. In order to receive water from the faucet, the bottom of the supporting rod 64 may be pushed. In this case, the angle pin 642 of the upper end of the supporting rod 64 engages with the push blade 632 of the push rod 63. The rod 63 is pushed. At this time, the upper end of the push blade 632 again pushes the side wing while engaging the bottom edge of the side wing 613 of the extension rod 612, the closed end 611 is separated from the through hole 52 to open the through hole 52 Do not close. Then, the water flows into the lower concave groove 53 along the through hole 52 and then flows out of the outer housing 50 through the flow hole 624 and the water through hole 72 to allow the user to perform a cleaning operation. Allow it to proceed.

After the cleaning operation is completed, simply pushing the support rod 64 again allows the guide block 643 to enter the guide groove 623 to be fixed to each other with the bottom of the guide groove 623. Then, the above-described respective engagement operation disappears, and thus the upper end of the closing end 611 is closed by the water pressure in an instant, so that the through hole 52 is closed, so that water cannot flow down.

As described above, the water supply time can be controlled by simple machine operation. When the water control valve is closed, the water in the water pipe still flows forward. Therefore, when the valve closes momentarily, a water hammer occurs, and the dynamic energy of the water flow is converted into elastic energy, creating a series of positive-negative pressure waves, until the energy is consumed by friction and stopped inside the water pipe. It oscillates while reciprocating. As a result, water pipe vibration occurs and noise is generated.
