Abstract

(57) [Summary] [Purpose] Installed between a main valve such as an underground fire hydrant or a water valve for water supply, and the pipeline, and work such as parts replacement and repair of the main valve without blocking the pipeline. Regarding the repair valve made possible. [Structure] In a repair valve installed between a main valve such as an underground fire hydrant and a water valve for a water supply and a pipeline, an operation lever-4 for opening and closing the valve body 2 of the repair valve is bent into a dogleg shape. When the valve body 2 is fully opened, the tip side 4 of the operation lever 4 is formed.
A closes the vertical position and occupies the horizontal position when fully closed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is a repair valve that is installed between a main valve such as an underground fire hydrant and a water valve for water supply and the pipeline so that work such as replacement of parts of the main valve or repair can be performed without blocking the pipeline. Regarding

[0002]

[Prior art]

 The conventional operating lever a for opening and closing this type of repair valve is configured in a straight line as shown in FIGS. For example, in FIG. 1, the solid line display position of the operation lever a is set to be fully closed, and the imaginary line display position is set to be fully open.

[0003]

[Problems to be solved by the device]

 By the way, in this case, with respect to each operation lever a, even if the opening / closing direction is displayed, it is general that the valve is installed in a narrow and not necessarily bright place. It is difficult to read the display, which may lead to erroneous operation, and the box for accommodating the repair valve becomes large due to the relatively wide rotation range of the operation lever, which is solved. That was also one of the challenges.

[0004]

[Means for Solving the Problems]

 In this invention, in the repair valve installed between the main valve such as the underground fire hydrant and the water valve for water supply and the pipe as described above, the operation lever for opening and closing the valve body of the repair valve is closed. The invention proposes a repair valve which is formed by bending the valve body so that the valve lever closes the vertical position when the valve body is fully opened and occupies the horizontal position when fully closed.

[0005]

The repair valve of the present invention having the above-mentioned structure is extremely easy to use without depending on any display means depending on whether the tip of the operating lever occupies the horizontal position or the vertical position. It is possible to recognize whether the valve body of the repair valve is fully closed or fully opened.

[0006]

【Example】

 Next, the present invention will be described in detail with reference to the embodiment shown in FIGS. 1 and 2 and the installation example shown in FIGS. First, in FIG. 2, 1 is a valve body of a repair valve, 2 is a valve body rotatably supported by a valve shaft 3 in the valve body 1, and one end side of the valve shaft 3 is extended. Then, the valve lever 1 is projected to the outside of the valve body 1, and a valve opening / closing operation lever-4 is attached to the end thereof.

In this invention, as shown in FIG. 1, the operation lever-4 is bent in a dogleg shape, and in FIG. 1, the tip side 4A of the operation lever-4 is located at a horizontal position (solid line display). ), The valve element 2 is fully closed, and when the vertical position (imaginary line display) is occupied, the valve body 2 is fully opened.

A state in which the repair valve 5 thus configured is applied to an underground fire hydrant facility is shown in FIGS. 3 and 4. First, referring to FIG. 3, a repair valve 5 of the present invention and an underground fire hydrant 8 connected to the repair valve 5 of the present invention are arranged on a connecting pipe 7 which is started up from a pipe line 6. It is housed inside.

At this time, the operation lever 4 of the repair valve 5 of the present invention is located at one end of the box 9 without occupying a symmetrical position at its fully closed and fully opened operation ends. It can be arranged close to one side, and therefore the position of the discharge port 11 of the underground fire hydrant 8 which is opened and closed by the operation of the main valve 10 can be brought close to the center position of the box 9, and when water is discharged. Bending of the hose can be eliminated.

[0010]

EFFECTS OF THE INVENTION According to the repair valve having the above-described structure of the present invention, the box for accommodating the repair valve can be made smaller than in the case where the conventional repair valve of this kind is rotated in the range of 45 ° left and right. The open / closed state of the valve can be recognized by the angle (horizontal or vertical) on the tip side of the operating lever, so that no display means is required and the valve can be repaired without error. This has the effect that the opening and closing operations can be performed.
