管遮断用バツグの挿入操作装置に関する。 More specifically, an opening that can be opened and closed by a shutter is formed in a saddle fixed to a fluid transport conduit, and a box communicating with the opening is attached, and a cylindrical bag insertion guide for storing a conduit blocking bag is inserted into the box. A hose for supplying and discharging pressurized fluid connected to the bag is inserted into the bag, and is attached to the bag so as to be slidable and rotatable in a sealed manner, and is removably inserted into the opening and the hole formed in the fluid transport conduit, and is connected to the bag. The present invention relates to a conduit-blocking bag insertion operation device in which a guide is slidably sealed and passed through the bag, and an inclined portion is formed at the tip of the bag insertion guide to select the insertion position of the bag in the conduit.

Conventionally, as shown in Japanese Utility Model Application Publication No. 53-90225, only one bag was stored in the bag insertion guide, and the bag insertion guide was inserted into an appropriate position by hand or visual inspection, and then the hose was inserted. The bag was inserted into the conduit, and the bag was expanded to block the inside of the conduit.

However, with just one bag, it is easy to be unable to shut off the conduit reliably, and it is also difficult to insert the bag in the correct position by feeling with your hands or visually checking the insertion position of the bag insertion guide. This problem easily occurs, and when the bag is inserted into the conduit from the bag insertion guide, there is a risk that the bag may get caught on the edge of the hole formed in the conduit and be damaged.Therefore, there is room for further improvement.
本考案の目的は、バツグによる導管遮断を容易
確実に信頼性の高い状態で行えるようにする点に
ある。 An object of the present invention is to make it possible to easily and reliably block a conduit with a bag.

作用効果は次の通りである。
The characteristic structure of the present invention is that two bags are stored in a bag insertion guide, a stopper is provided on the bag insertion guide to make contact with the box in order to determine the proper insertion position, and a stopper is provided on the bag insertion guide to connect the inside and outside of the bag. The reason is that an on-off valve is provided, and its effects are as follows.
つまり、２個のバツグを収納させてあるから、

状態が得られる。
In other words, since it stores two bugs,
By inserting the bag insertion guide into the conduit, first insert one bag into the conduit and inflate it, then rotate the bag insertion guide 180 degrees and insert the other bag into the conduit and inflate it. The conduit can be blocked with two bags on both sides of the bag insertion guide, and a more reliable conduit blocking state can be obtained than when the conduit is blocked with one bag as in the prior art described above.

無くせ、このことによつても信頼性の高い導管遮
断状態を確実に得られる。 In addition, since the bag insertion guide can be easily and reliably inserted into the proper position by the contact between the stopper of the bag insertion guide and the box, when inserting the bag into the conduit from the bag insertion guide, the bag can be inserted by the edge of the hole in the conduit. An inconvenient situation in which the bag is damaged can be reliably eliminated, and a highly reliable conduit disconnection state can thereby also be reliably obtained.

を完全なものにできる。 Furthermore, the box that communicates between the bags in the conduit through the hole in the conduit and the opening in the saddle is equipped with an on-off valve to communicate between the inside and outside of the box, so a pressure gauge can be connected to the on-off valve to By measuring the pressure, it is possible to actually check whether the conduit is blocked by the bag, thereby making the conduit blocking completely reliable.
その結果、導管遮断を容易にかつ極めて信頼性

As a result, it has become possible to provide a conduit-blocking bag insertion operating device with even better performance, which allows conduit-blocking to be performed easily and with extremely high reliability.
