Description

[0001] The present invention relates to a manhole having a valve handle,

The present invention relates to a manhole having a valve handle storage, and more particularly, to a manhole provided in a manhole for storing a valve handle for opening and closing a ball valve, And more particularly, to a manhole having a valve handle storage that can be easily managed and used.

As shown in FIG. 1, a manhole installed on a road is a structure in which a lid is coupled to a manhole support, and a lid is opened to enter a built-in space to supply a city gas, a pipeline, And maintenance.

Especially, in case of emergency, a blocking ball valve is installed so as to shut off the flow of fluid, and a ball valve is opened and closed by connecting a valve handle on the ground.

As shown in FIG. 2, the ball valve installed in the manhole is provided inside the manhole and interrupts the fluid moving to the pipe. The ball valve is installed so as to protrude above the ball valve and rotates the drive shaft having a square- So that it can be opened and closed.

Since the conventional valve handle is generally stored in the bottom of a manhole, when rainwater or foreign matter flows into the manhole through the manhole, corrosion of the valve handle is caused to shorten the service life, There is a problem that it is difficult to increase the time for opening and closing the ball valve and maintenance of the valve handle.

In order to solve the problems of the related art, the present invention is applied to a manhole in which a valve handle for opening and closing a ball valve installed in the underground is stored, thereby effectively preventing water and foreign matter from entering the valve handle. Thereby simplifying fabrication, assembly, and manipulation.

The present invention relates to a manhole cover, A storage compartment is formed on the lower surface of the inner lid which is openably and closably provided in the manhole support, and the storage compartment has a mounting table formed with mounting grooves for inserting and fixing the valve handle on the front surface thereof; And a cover coupled to the mounting table, wherein the storage box has a mounting table formed with a fixing groove for inserting and fixing a valve handle on a front surface thereof; And is formed as a cover which is superimposed on the mounting table.

Further, the storage box is fixed to the inner lid by bolting or joining.

Meanwhile, the lid has a support for preventing the valve handle from being separated from the inner surface, and protrusions are formed on the inner circumferential surface of the mounting recess so that the valve handle is not released so that the valve handle is stored in a stable and clean state Can be used.

INDUSTRIAL APPLICABILITY The present invention can prevent corrosion of a valve handle by isolating a valve handle from rainwater or foreign matter flowing into a manhole, and can improve maintenance and ease of use of the valve handle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 to 7, a manhole having a valve handle storage box according to the present invention includes a manhole pedestal 12 and a storage case installed at a lower portion of a inner lid 13 which is openably and closably provided in a manhole pedestal 12, The storage box 100 is fixed to the inner lid 13 by bolting, welding, welding, adhesive or the like, and the rainwater or foreign matter flowing into the manhole 10 is adhered to the valve handle 20 ), It is possible to suppress the corrosion of the valve handle 20 and simplify the structure of the maintenance and storage box 100 so that the manufacturing and the operation can be facilitated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the constituent elements of a manhole having a valve handle storage box according to the present invention will be described with reference to the accompanying drawings.

3 and 4, the bolt B inserted into the plurality of bolt holes 15 formed in the inner lid 13 and the bolt B inserted into the outer front surface of the storage box 100, according to an embodiment of the valve handle storage box of the present invention, A plurality of bolt coupling grooves 150 formed on the inner lid 13 are threadedly engaged with the bolts B and the O-ring O inserted in the tightening portions of the bolts B and the inner lid 13 to effectively block rainwater, foreign substances, .

The manhole cover 12 is formed by a vertical portion and a flange. The upper and lower stopping protrusions are formed at the upper and lower portions of the inside of the vertical portion, and the cover 11 is formed on the upper stopping chin of the manhole cover 12 And the inner lid 13 is positioned above the lower stopping jaw of the manhole support 12.
