求されていた。2. Description of the Related Art Conventionally, the connection and disconnection of pipes arranged in various pipe systems are performed in various cases such as when the pipes are directly press-fitted or when the pipes are of the flange connection type, or when the packing is replaced. However, in any of these cases, when the environmental conditions, the type of fluid in the pipe, or especially the time elapsed after connection is long, the surfaces pressed against each other may be firmly fixed to each other. If not,
All of them required a great deal of time and labor for their removal. Particularly, as the pipe diameter becomes larger, more difficult work is required.

ない。In particular, in the case of exchanging functional equipment for piping such as a valve arranged at a pipe connecting portion, especially the exchange of a large-sized valve is often executed after a relatively long period of time. Due to chemical changes or deposition of impurities,
It may be stuck in a state that is extremely difficult to separate. Especially in a piping system where high-temperature steam or the like flows, rusting is promoted due to temperature and humidity, which makes opening and closing work even more difficult, and under adverse conditions such as when installed in a narrow space. There are quite a few things that have to be done.

が必要であった。Normally, the opening of these large valves is carried out by press-fitting a tool such as a bar into the abutting surface of the connecting flange portion.
It is not unusual for it to take an extremely long time. In addition, once opened, there is a risk that the valve will fall due to the weight of the valve itself.Therefore, in order to prevent this, a chain block, etc. should be installed in advance to suspend and hold the valve before embarking on the opening operation. Need to use. That is, additional means were needed to ensure that the opened valve was held securely.
