Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tool for repairing a gas tank without gas leakage and without stopping the gas supply.

[Conventional technology]

Conventionally, in order to repair a gas tank whose stopper cannot be opened or closed due to grease sticking, etc., it is necessary to close the valve on the upstream side of the piping, then disassemble the stopper, take out the stopper, clean it, and apply grease. It was being reassembled. At this time, it was necessary to ask all gas consumers following the closed valve to stop using gas until the construction work was completed.

Further, if there is no valve on the upstream side of the piping of the pot requiring repair, instantaneous gas leakage is inevitable when the pot is disassembled for repair, which is not desirable in terms of safety during repair. Naturally, the gas supply is also stopped in this case.

[Problem that the invention attempts to solve]

Previously, when repairing a gas tank as described above, it was necessary to obtain the consent of all downstream customers to suspend gas supply. However, there are some customers who simply cannot interrupt the gas supply, and in these cases it is not possible to disassemble and repair the gas tank.

The present invention aims to provide a repair bag that allows gas tank to be disassembled and repaired without leakage while continuing to supply gas.

[Means for solving problems]

The gist of this invention is that flexible, airtight left and right gloves that can be freely operated from the outside are placed inside a transparent and soft resin bag with an opening with a brim that can be attached to the top of the Kotuku body. A relatively hard annular ring is wound as a core material and attached to the insertion opening of the glove, the resin bag and the glove are glued together, and a rubber plate is adhered to the outside of the glued bag and the glove. This is a bag for disassembling and repairing a bag, characterized in that a glove is airtightly provided in a bag body made of aluminum, and a groove is further provided on the outer surface of the brim portion.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

The bag body 1 is made of a transparent and thin soft resin, such as soft vinyl chloride, and is formed into an airtight bag by joining a cylindrical portion 11 and both end face portions 12, 12' by welding. Holes 13 and 13' are provided at the center of both end face portions 12 and 12', and an opening 14 is provided at the lower center of the cylindrical portion 11. The vinyl gloves 2, 2' are placed inside the bag body 1, and rings 22, 22' made of hard rubber or synthetic resin are used as core materials to hold the shape inside the insertion opening of the gloves.
The vinyl gloves 2,
2' inside the bag body 1. Further, for reinforcement, ring-shaped rubber plates 24, 24' are bonded with adhesive so as to span the end faces of the collar portions 23, 23' and the end face portions 12, 12' of the bag body 1.

A rubber ring 3 having an L-shaped cross section and a collar 31 is bonded to the opening 14 around the opening 14 of the bag body 1 using an adhesive or the like. A groove 33 is provided in the collar 31 of the rubber ring 3 to facilitate tightening with a nylon band 4 or the like to the open end of the lock body 1.

A method of using the bag for disassembly and repair constructed as described above will be explained below.

When repairing the Kotoku 5 with piping connected, first remove the nuts, etc., and then remove the plug 5 inside the Kotuku main body.
1 is loosened to the extent that it can be pulled out by hand, and inside the bag body 1 is a rubber plug 5 that matches the diameter of the plug 51.
Enter 3. First, the collar 31 of the rubber ring 3 is fitted around the outer periphery of the upper part 52 of the bag body, and the nylon band 4 is tightened from above to attach the bag body 1.

Next, put both hands into the vinyl gloves 2, 2', pull out the stopper 51, and insert the rubber stopper 53 placed inside the bag into the opening from which the stopper 51 was removed at the top of the bag body. Gas fills inside the bag while the plug 51 is removed and the rubber plug 53 is inserted, so close the opening 14 with one vinyl glove, loosen the nylon band 4, remove the bag body 1 from the container 5, and remove it from the outside with a well-ventilated area. take it to

Thereafter, the stopper 51 is taken out from inside the bag, cleaned and repaired, and grease is applied, and the rubber stopper 53 and the stopper 51 of the bag 5 are replaced by the reverse procedure of removing the stopper 51.

FIG. 2 shows another embodiment of the present invention, in which an adapter 6 is used between the bag 5 and the bag body 1.

The adapter 6 is provided with a hole 8 that matches the opening of the pot 5, and is connected to the pot 5 through the gasket 7.
It is fixed to the pipe 10 with a U bolt 6' provided on the top surface. A cylindrical part 9 is provided in the upper part of the hole 8, and the collar part 31 of the bag body 1 can be attached to the outer periphery of this cylindrical part 9.

FIG. 3 shows another embodiment of the present invention, and is a diagram of the attachment portion of the vinyl glove 2 and the ring 22.

A ring 22 is fitted onto the outer surface of the mouth part of the vinyl glove 2, and the mouth part of the vinyl glove 2 is rolled up from the end side to form a brim part 23. Note that the connection between the end surface portion 12 of the bag body 1 and the ring-shaped rubber plate 24 is the same as that shown in FIG.

Next, FIG. 4 shows another embodiment in which a vinyl glove 22' is placed inside the bag body 1 from the sides and top thereof, and the bag body 1 is formed into a rectangular shape.

[Effect of idea]

In the present invention, due to the above-described structure, the insertion opening of the glove is always open, making it easy to insert the hand. Additionally, the ring allows for strong adhesion between the bag and the glove, ensuring airtightness.

Therefore, the Kotuku can be disassembled and repaired while the pipes are still connected while the gas inside is flowing, and the Kotuku can be repaired without causing any inconvenience to customers downstream of the Kotuku, and without any leakage.
