本考案は、都市ガスなどの本管に分岐管を不断
流状態(導管に流体を流動させたままの状態)で
接続する際に用いる分岐用チーズの内部流路を遮
断する閉子の開閉操作用具に関する。[Detailed description of the invention] [Industrial application field] This invention is a branch pipe used when connecting a branch pipe to a main pipe such as city gas in a non-flow state (a state in which fluid continues to flow in the pipe). This invention relates to an opening/closing operation tool for a closure that blocks the internal flow path of cheese.

る。
Conventionally, the branching cheese used when connecting a branch pipe to a main pipe such as city gas, which has relatively low gas pressure, in a non-flow state, is a joint called a valve tee, which has a built-in closure that shuts off the internal flow path. A method is used in which the cheese is screwed into the screw hole of the main pipe using a shutter device without blowing out gas.
しかし、本管のガス圧が高い場合に、本管から
大きく突出するバルブチーをガスが噴出しない状
態でねじ込むためにはシヤツター装置をバルブチ
ーが入る大きさにする必要があつた。 However, when the gas pressure in the main pipe is high, it is necessary to make the shutter device large enough to accommodate the valve chi, which protrudes largely from the main pipe, in order to screw in the valve chi without gas gushing out.

のために刻設してある、という方式が提案されて
いる。 For this reason, even when the gas pressure in the main pipe is high, it is recommended to attach the cheese to the main pipe as a branching cheese that can be screwed into the main pipe without blowing out gas using the simple shutter device that has been used in the past. A method has been proposed in which a nipple is screwed forward only at the transition portion from the tube to the cheese, and the external thread of this nipple is carved for screwing into the cheese.

In the above-mentioned cheese with a nipple and a closure, there is a branched flow blocking position in which the closure is screwed onto the nipple, and a branched flow allowing position in which the closure is removed from the nipple and held in a vacant space within the cheese. In connection with the above proposal, there is a strong need for an appropriate opening/closing operation tool that allows the closure to be easily and reliably engaged.

In order to meet this demand, the present invention provides a closure that is built into a branching tee connected to a fluid transport conduit in a state in which the internal flow path is blocked by screwing the closure into the branching tee.
The tool is for opening and closing the tee by operating from outside the tee in an uninterrupted flow state, and includes an inner shaft whose tip thread portion can be screwed into the closure and an outer cylindrical shaft whose tip different diameter portion can be engaged with the closure in an integrally rotating state, and is fitted with inner and outer double sealed sleeves in a relatively rotatable state, and a lid that can be sealedly joined to the insertion opening of the tee is externally fitted to the outer cylindrical shaft in a sealed state so as to allow the outer cylindrical shaft to rotate and slide relative to the inner cylindrical shaft,
The present invention provides an opening and closing tool for a branching tee closure, characterized in that a grip for rotation is attached to each of the outer protruding ends of the inner shaft and the outer cylindrical shaft.

To make the closure take the branch flow blocking position, turn the inner shaft whose tip is screwed into the closure and the outer cylinder shaft inserted through it, and close it toward the nipple on the inner surface of the joint between the main pipe and the cheese. Advance the lock and screw the closure into the nipple using the different diameter section at the tip of the outer cylinder shaft. Next, by turning only the inner shaft in the opposite direction and unscrewing it from the closure, the inner shaft and the outer cylindrical shaft can be removed from the closure.

択的に回すのみで行うことができる。 To make the closure take the branch flow permissible position, engage the screw at the tip of the inner cylinder and the different diameter portion at the tip of the outer cylinder shaft, and turn both shafts in the opposite direction to the above. Since the child comes off from the nipple, it is only necessary to grasp the child with the threaded portion at the tip of the inner cylinder, release it from the nipple, and store it in the hollow space within the cheese. For this storage, a threaded part other than the above-mentioned threaded part of the closure may be used and screwed onto the threaded part of the free end of the cheese. These operations can be performed simply by selectively turning the removable rotary handles for both shafts on the outside of the cheese.

As described above, the operating tool of the present invention is useful when connecting a branch pipe in a non-flow state (with fluid flowing through the pipe) via a nipple that has been previously attached to a fluid transport pipe such as city gas. It is suitable to be set in the branching cheese used for the branching cheese, and on the other hand, it is built in in advance in this branching cheese, and when connecting the cheese to the conduit, the cheese internal flow path is shut off by tightening the screw to the nipple. An appropriate opening/closing tool for a branching cheese closure is provided, which opens and closes the closure in a state where the branching cheese closure is in a state where the branch pipe is connected in order to open or, if necessary, shut off the flow path after the branch pipe is connected. In other words, unlike the conventional permanent type, it can be reused by making it removable for the branching cheese, and it also ensures good leakage prevention while ensuring reliable rotation for the screw type closure. In addition to being able to apply operating force, it is possible to reliably prevent accidental falling off of the closure when it is rotated, pulled out, or pushed in, and overall safety and workability can be improved all at once.

A cheese body C 2 externally fitted and screwed onto the nipple C 1 and fixed to the conduit P by welding etc.
It is composed of. Closure B blocks off internal flow path F of this cheese C. The canopy part 10 of the cheese body C is provided with the operating tool A and the lid 3.
A screw hole 10a is formed into which the screw 3a is screwed,
In addition, an annular sealing material 11 is fitted on the lower surface.

Thereafter, at the same time as the shutter is opened, the nipple C1 with the closure B is screwed into the screw hole P1 , and after removing the saddle, the cheese body C2 is screwed into the nipple C1 . Then, the opening/closing operation tool A is set on the cheese C. This is the situation shown in FIG.

盲栓(図外)を螺合することが望ましい。 Next, when both grips 1a and 1b are held together and rotated, the rotational operation force is transmitted through the different diameter engagement portions.
Closure B separates from the nipple. After pulling up the operating tool A holding the closure B, rotate the closure B again in the same manner as described above to screw the closure B into the screw hole 10a of the screw 8 of the canopy part 10 and into the sealing material 11 of the top plate 7. It is held tightly by crimping (Fig. 3). During this time, the threaded connection of the threaded portion 1a to the female thread 7a is maintained, so that the closure member B is reliably prevented from accidentally falling off during the rotation or pulling operation. Thereafter, the operating tool A is removed from the closure B and then pulled out from the cheese C, but it is desirable to screw a blind plug (not shown) into the screw hole 10a.
