Description

Self-Resistant Light-emitting Valve Cap for Water Separation Valve {WATER VALVE WITH CAP DETECTABLE EASILY}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a valve cap for a water discharge valve used in a water supply system for water supply, and more particularly, for a water discharge valve installed in a valve chamber or a valve box without a separate light and manually opened and closed by a valve key. Relates to a valve cap.

The water valve (gate valve or butterfly valve) installed inside the valve chamber or under the valve box is a metal valve (mainly cast iron or steel, as follows) because the operator needs to open the water valve outside the valve chamber or the valve box. Most of the key open / close valves that are opened and closed by the key (see FIG. 7). The valve key consists of a key box with a rectangular hollow, a handle that can be held and turned by a worker, and a long stem that connects the key box and the handle. Therefore, all the water valves operated by the valve key have a valve stem, and a metal valve cap having a square head inserted into the key box of the valve key is attached to the upper end of the valve stem. The valve cap can be disassembled from the valve body. When assembling, insert the upper end of the valve seat into the valve seat coupling hole formed in the neck of the valve cap and fasten it with bolts. Although only an example of a gate valve is shown in the figure, a butterfly valve also has a metal valve cap.

The dilution valve operated by the valve key has a rubber valve disc inside the metal valve body, and the water flows by raising or lowering the disc (in the case of a gate valve) or by rotating the disc (in the case of a butterfly valve). Open and close As described above, the metal valve stem is coupled to the upper portion of the valve disc, the valve stem is rotatably supported by the cover of the valve body, and when the valve stem is rotated, the valve is opened and closed according to the rotation direction.

Most tap water valves are buried underground. If the distillation valve or piping is installed shallowly from the ground, the distillation valve or the piping may be damaged by the pressure or shock applied from the ground, so the valve chamber should be as low as 1 ~ 2m and as deep as 8 ~ 10m. Or install a valve box and install a water valve. If the valve room is wide enough to allow the operator to enter and exit, it also functions as a manhole, in which case the ground opening is closed with a manhole cover. However, in the case where the valve chamber is narrow or only the valve box is installed without the valve chamber, the worker cannot enter or exit the interior, and the ground opening is closed with a tow. Since the space where the distillation valve is installed is a valve chamber or a valve box in the ground, water and earth and sand are easily introduced around the distillation valve and are dark even during the day because there is no separate lighting. Therefore, when it is necessary to open and close the dividing valve, the operator grasps the handle of the valve key, shakes the key box, and roughly grasps the position of the valve cap by hitting the valve cap. do. If the depth of installation of the valve chamber or the valve box is deep, the stem length of the valve key will be increased accordingly, and more trial and error will be required in fitting the key box of the valve key to the valve cap.

The present invention, which is designed to solve the problem of manual manual valve opening and closing using the conventional valve key described above, can easily find a valve cap of a dilution valve installed in a valve box or a valve chamber on the ground, and detect a valve cap position capable of inserting a valve key. It is an object of the present invention to provide a self-sensing light emitting valve cap for a dilution valve that is easy to use.

Another object of the present invention is to provide a self-sensitive light emitting valve cap for a dilution valve that can protect the self-sensitive light emitting unit from impact, moisture, foreign matters, or the like.

In the present invention to achieve the above object, in the valve cap for the water-reducing valve having a square head is inserted into the key box of the valve key, the square head of the valve cap to form a groove that is open upwards, the inside of the groove An LED (LED), a battery capable of supplying power to the LED, and is closed only when a magnet approaches, characterized in that it comprises a reed switch for controlling the power supply of the battery to electrically connect the LED to the LED.

In addition, the present invention, the LED, the battery and the reed switch is mounted on a single printed circuit board (mounting) and inserted into the groove of the square head, the empty space around the printed circuit board is filled with epoxy resin or silicone resin It is characterized by.

According to the present invention having the above-described configuration, if a magnet is provided on the inner surface or the outer surface of the key box of the valve key, and the valve key is lowered to the valve box or the valve chamber from the ground, the key box of the valve key approaches the valve cap. The flashing of the valve cap is temporary (only while the key box is in close proximity to the valve cap) so that not only can the valve cap be precisely located but also the key box of the valve key can be correctly inserted into the square head of the valve cap. When the valve key is removed from the valve cap, the power to the LED is automatically cut off, thereby minimizing the power consumption of the light emitting unit. There is an effect that the light emitting unit can be used for a long time.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a self-sensitive light-emitting valve cap for a water valve according to the present invention will be described in detail.
