Description

DETAILED DESCRIPTION OF THE INVENTION This backing is used as a fluid pipe transport container (hereinafter abbreviated as capsule).

It is suitable as a backing for items that are subject to external pressure from fluids such as liquids and gases that are frequently opened and closed.

A. Screws etc. that are widely used as backing.
Those that tighten strongly are cumbersome and inconvenient as backings for items that are frequently opened and closed.

B. As a device that attempts to utilize external pressure,
- There is a gasket No. 24745 that receives external pressure inside the U-shape as shown in Figure 1, and closes by compressing the body on both rows, but it is unreasonable for the following reasons. It is.

(t) 6', ? 'Precise finishing of the surface is required.

(2) If asbestos gasket, like lead backing, 6', depending on the tightening? If we want to get familiarity with the ' part, there should not be a space of 14'.

The strength of the springs 12' and 13' and the degree to which the gasket body adjusts when tightened are mutually contradictory.

A substance that easily adapts will have weak springiness, and if the springiness is strong, it will not adapt easily.

(3) When pressure is applied to the space 14', the top and bottom deform as shown by dotted lines, and the outer periphery begins to peel off.

Also, the air pressure at the 10' and 11' sections increases, and the air pressure at the 6' and 7' sections increases.
The contact pressure of the contact surface is reduced.

The same applies to high temperatures.

(4) 8' and 9' pipes and gaskets are of course not made of the same material or have the same volume, so the expansion/contraction speed and degree of expansion and contraction in response to temperature changes are different, and the outer edges of the gaskets may wave because they cannot respond to local changes. can also be considered.

In other words, the cited example is not a reasonable structure for a gasket in many respects.

In particular, it cannot be used for the purpose of the invention, where you can feel safe just by slamming the lid on.

As a backing for C double structure, Utility Model Application No. 48-9157
There is a No. 5 model as shown in Figure 2, but this simply has a net stop γ'b between both bodies to prevent the backing from being pushed out due to internal pressure, and the backing T The tip of B and C clearly protrudes from the joint surface, and the substantial effects of B and C are no different from A.

D In something similar to this, the contact surface between the main body and the backing is precisely finished, and the blade-shaped backing is brought into contact.

For example, there are U-shaped backings used for rotating parts of machines, but D has the same drawbacks as described in (1) and (4) of B.

In addition, both B and D are pressed outward from the inside of the backing to expect a backing effect.

The invention is to close two backings separately attached to the main body by compressing them from the outside of the combined surface.
Figures 4, 5, 6, and 9 show the case where the present invention is used in a capsule for transporting body pipes.

In the figure, 1 is a pipe, 2 is a capsule, 3 is a pressurized fluid, 4 is a collar, 5 and 6 are the main body (in this case, 5 is a capsule container, and 6 is a lid), 1 is a homogeneous annular backing, 8
The tip of the backing is made thinner to facilitate merging.
In addition, in order to create a space where the fluid can be suppressed, the rectangular cross section of the flat backing is cut off diagonally, 9 is the triangular part left after cutting off, and 10 is inside the capsule, 11 is the backing 7 The tip of the tongue, 12 is the pressure of the fluid, 13 is the cut-off surface of 8, and the continuous air is separately glued to the cut-off surface of 8 so that it fits between the cut-off surface of 8, the main body 6, and the collar 4. Cystic cyst (hereinafter abbreviated as sponge).

), 14 is the adhesive surface of the lid 6, collar 4 and backing 7, 1
Reference numeral 5 denotes a combined surface of the backing and the backing, and 16 a magnet which is attached to the main body 6, the collar 4, and the backing 7 so that the head is buried in the backing 7 and they are attracted to each other.

If the head is exposed, it is necessary to sink it slightly below the merging surface of the backing, taking into consideration the compression of the backing.

In this way, airtightness is maintained between the main bodies 5, 6 and the backing by adhesive, and between the upper and lower backings, the upper and lower backings are of the same quality, the same thickness, and expand and contract equally due to temperature changes. Even if something happens, the tip of the tongue 9 (tip 11) becomes thin (
Because of this, they blend well with each other, and the fluid to be blocked presses against the upper and lower cut surfaces 8, so that a perfect backing effect can be expected.

In the case of such a backing, initial merging becomes a problem, and care must be taken to ensure that the backing becomes as tight as possible. However, in such a case, it can be prevented by tightening the sponge 13 as described above.

When adhering the sponge 13 to the cut surface 8, if adhering it to the entire surface would impair the merging function of the tongue tip 11, attach it only to the thick part of the tongue 9 to the extent that the sponge 13 does not escape. It is better to do it like this.

In this way, the sponge 13 presses the tongue 9 from above and below to help the initial merging, and since it is a continuous pneumatic cyst, the fluid 3 penetrates through it, and the same process occurs without the sponge 13. Ensure backing effect.

If the backing 7 is small, the number of wave nails is also small (, sponge 13
(However, the upper and lower tongues 9 maintain a good planar shape and merge.

Also, applying oil or the like to this merging surface has the effect of aiding the initial merging, but it must not be something that would deform the backing.

The magnet 16 connects the main bodies 5 and 6 by attraction.

It goes without saying that if you are concerned about using magnets alone, you will need other auxiliary means, such as attaching a hinge to the right end of the main bodies 5 and 6, attaching a mesh stopper to the left end, or tightening with a bold wire.

Some may argue that it is the same thing, but in the case of this backing, even if it has some loose points such as one line or looseness, it can fully perform its function.

Figures 7 and 8 show the case where the tongue tip 11 is made by pasting another material onto the tongue 9, and 17 shows the tongue tip that has been pasted.

This is because if the backing 7 is made of a relatively hard material, it is difficult to make the tip of the tongue 9 sufficiently flexible even if it is thinned.
This is to make it easier to select the material.

FIG. 10 shows a case where the backing of the present invention is used for a pipe joint, and 18 indicates a tightening bolt.

In this way, even if the joint loosens somewhat due to vibrations, it will not leak immediately, and the joint can be made to withstand vibrations with such a loose joint from the beginning.

As is clear from the above explanation, while conventional backings tend to leak more easily as the pressure increases, this backing closes more completely as the pressure increases.

It is easier and more convenient to use than conventional backings, and is particularly useful for lids of containers that are frequently opened and closed.

It can also be used in cases where double closure is required on the inside and outside, and it is impossible to reach inside once the lid is closed.

Claims (1)

[Claims] 1. Align the rectangular cross-section of the flat annular backing with the two backings each having a diagonally cut-off tongue so that the wide joining surface is symmetrical, and the opposite adhesive surface parallel to the two backings is adhered to the main body separately. The backing is designed so that the pressure of the fluid presses against the cut surface, closing the tongue from the tip of the tongue and preventing fluid from entering.
