Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea was developed to ensure that tanks are watertight or airtight at the block stage during ship construction. Fixed to the tank when performing water pressure test or air test to check tightness. Concerning plugging fittings for air vent pipes or sounding pipes that are not equipped with pipe head fittings. It is.

0002

[Conventional technology]

Conventionally, this type of device has not been specially devised, and it is not necessary to test the water pressure of the tank or When performing an attest, place a wooden plug or cloth into the top opening of the air vent pipe or sounding pipe. It is known that the top opening is closed by stuffing it with

0003

[Problem that the idea aims to solve]

As described in the conventional technology, a wooden plug or a It takes time to fill the top opening with a wooden plug or cloth. In addition, there was a problem in that watertightness or oiltightness was unreliable.

0004 This invention was made in view of such problems with the conventional technology. Its purpose is to be easy to install and remove, and to be watertight or oiltight. Pipe fittings for tank water pressure tests or air tests that ensure high reliability. This is what we are trying to provide.

[0005]

[Means to solve the problem]

In order to achieve the above purpose, this invention carries out water pressure test or air test. If the tube head fittings installed on the tank surround the upper end of an unequipped air bleed tube or sounding tube. Attach one vertical connection part with a hinge so that it can be opened and closed freely, and connect the other vertical connection part with a hinge. The side of the holding metal fitting, which fixes the connection part of the Insert the upper surface of the holding fixture with a nut fixed onto the top of the hole, the nut and the through hole. A gasket is interposed at the upper end of the air bleed pipe or the sounding pipe. Press the top surface of the presser cover with the presser bolt and press the presser cover to be placed on the air vent pipe or It is made by blocking the opening of a sounding tube.

[0006]

[Effect]

The presser cover, which is pressed and fixed with a presser bolt, has an elastic gasket in between. Therefore, be sure to seal the opening at the top of the air bleed tube or sounding tube.

[0007] The holding bracket, which can be opened and closed with a hinge, can be attached to the top end of an air vent pipe or sounding pipe. Easily removed and can be installed and removed in a short time.

[0008]

【Example】

The embodiment will be explained using drawings, as shown in FIGS. 1, 2, and 3. A vertical pipe is installed surrounding the upper end of the air bleed pipe 1 provided in the tank to be tested for water pressure. In the two split holding fittings 2 and 3 for occluded tubes, one vertical side of the holding fittings 2 and 3 is The split connection part is held by the hinge 7 so that it can be opened and closed freely, and the other side of the holding fittings 2 and 3 The vertically divided connection portions are fixed with bolts 8.

[0009] A through hole 9 is provided on the upper surface of the holding fitting 2, and a nut 10 is fixedly installed on the upper part of the through hole 9. The holding bolt 4 is inserted into the nut 10 and the through hole 9.

0010 Place the presser cover 5 on the upper end of the air vent pipe 1 with the gasket 6 interposed, and then tighten the presser bolt. 5, the upper surface of the presser cover 5 is pressed to close the opening of the air vent tube 1.

[0011] In this embodiment, when closing the upper end opening of the air vent pipe 1, first close the hinge 7. Rotate the holding fittings 2 and 3 around the center to open them, and surround the upper end of the air vent pipe 1. Then, close the holding fittings 2 and 3 and fix the vertically divided connection part with the bolt 8.

0012 Next, insert the presser bolt 4 into the nut 10 and the through hole 9, and Push the presser bolt 4 onto the top surface of the presser cover 5 placed on the end while screwing it into the nut 10. and close the upper end opening of the air vent pipe 1.

[0013]

[Effect of the idea]

Since this invention is configured as described above, it produces the effects described below. Use the presser bolt to press the presser cover onto the top end of the air bleed tube or sounding tube that is not equipped with a tube head fitting. By closing the opening, it maintains high watertightness and is suitable for tank water pressure tests and The vertically divided retainer can be opened and closed with a hinge. Because it is fixed with bolts, the holding bracket can be easily attached to the upper end of the air vent pipe or sounding pipe. It can be attached and removed.
