The present invention relates to an open / closed state display device of a valve, and more particularly, to allow a user to easily identify the open / closed state of the valve, and to easily check the open / closed state of the valve even in a dark place or a long distance, thus preventing gas accidents. The present invention relates to an open / closed state display device of a valve which can be easily assembled and used in an existing valve.

In general, city gas (LNG) and propane gas (LPG) are supplied to gas appliances such as gas stoves and ovens through piping pipes.

At this time, a valve is installed in the middle of the pipe to supply or shut off the gas.

When the gas is used, the user opens the valve so that the gas can be supplied to the gas appliance. When the gas is stopped, the user can lock the valve to block the gas from being supplied to the gas appliance.

1 is a perspective view of a state in which a valve is installed in a pipe according to the prior art.

As shown in FIG. 1, the pipe 10 to which liquid or gas is transferred according to the related art is provided with a valve 20 for controlling a flow of liquid or gas.

In addition, the valve 20 is provided with a valve handle 22 so that the user can control the flow of liquid or gas.

Here, the valve handle 22 is rotatably provided in the valve 20, the valve 20 is opened or closed in accordance with the rotation to interrupt the flow of liquid or gas.

However, the valve according to the prior art can check the opening and closing state of the valve only by the direction of the valve handle was not easy to identify by the user, and it is difficult to check whether the valve is opened or closed in a dark place or a long distance, so that the valve is not identified. There was a risk of gas leaks.

The open / closed state display device of the valve according to the present invention has been devised in view of this point, so that the user can easily identify the open / closed state of the valve, and can easily check the open / closed state of the valve even in a dark place or a long distance, thereby causing a gas leak The purpose is to prevent them.

Another object of the present invention is to provide an open / closed state display device for a valve which can be easily assembled and used to an existing valve and pipe in which the open / closed state display device for a valve is not installed.

In order to achieve the above object, the opening and closing state display device of the valve according to the present invention is integrally formed around the valve handle of the valve connected to the pipe to control the flow of liquid or gas, and a rotating member having a check unit on both sides, It is formed integrally with the valve, characterized in that it comprises a display member is displayed on the display phrase so that the opening and closing state of the valve handle through the confirmation portion of the rotating member is displayed.

In order to achieve the above object, the opening and closing state display device of the valve according to the present invention is connected to the pipe and the cover member is detachably assembled to the valve handle of the valve to control the flow of liquid or gas, and integrally around the cover member And a rotating member having a check unit on both sides, and a display member assembled to the valve so that a display phrase is displayed to check the opening / closing state of the valve handle through the check unit of the rotating member. It is done.

In addition, the cover member is preferably provided with a friction member to increase the frictional force with the valve handle surface on the inner peripheral surface so as not to be easily separated from the valve handle.

In addition, the display member is preferably provided with a clip member to be assembled and detached to the valve.

In addition, the identification unit of the rotating member is preferably formed to penetrate both sides of each side of the rotating member so as to confirm the display phrase of the display member.

In addition, the identification portion of the rotating member is preferably provided with a convex member so that the display phrase of the display member can be seen better.

In addition, it is preferable that the display member is displayed to face each other display phrases indicating the same state of the opening and closing state of the valve.

In addition, it is preferable that the display member is coated using different colors around the display phrase indicating the open / closed state of the valve so that a user can more easily identify the open / closed state of the valve.

In addition, the display member is preferably provided with a phosphor layer made of a phosphor material on the display phrase and the periphery of the display member so that even in a dark place.

Hereinafter, an embodiment of an open / close state display device of a valve according to the present invention will be described with reference to the accompanying drawings.

In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description.
