Abstract

(57) [Summary] (Modified) [Purpose] The present invention has an object to solve the deterioration of the appearance of a gasket and to prevent an injury due to a broken part such as a core metal of the gasket. [Structure] Gasket part 4 required for sealing function
In the gasket 1 in which the gripping allowance 6 and the gripping allowance 6 are integrated, a manually separable part is provided between the gasket part and the picking allowance with the minimum cross section necessary to support the gasket part.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gasket which is interposed between flange parts made of metal and prevents gas or liquid from escaping from the flange parts.

[0002]

[Prior art]

 In this type of conventional gasket, it is cut into the same shape as the metal flange to be connected, the gasket is interposed between the flanges, the flanges on both sides are tightened with bolts, etc., and the flanges are sealed with a gasket. Was there.

However, in such a gasket, the gasket moves while being sandwiched between the flanges and tightened with bolts or the like, the sealing between the flanges becomes incomplete, or the gaskets are not removed from between the flanges. There was a risk that it would appear unsightly.

Therefore, a gasket as shown in FIG. 2 has been proposed. In this gasket 1, an additional portion 3 shown by a two-dot chain line is added to a gasket portion 2 having the same flange shape as shown by a solid line. It is what

This gasket 1 has an additional portion 3 added thereto, and after being inserted between the flanges, by tightening the flange while continuing to support the gasket portion 2, the gasket portion 2 does not shift from the flanges. It is designed to be sandwiched in place.

As a specific example of a conventional gasket having no additional portion serving as a picking margin, a turbocharger mounting gasket disclosed in Japanese Utility Model Publication No. 1-158850 and an insulator disclosed in Japanese Utility Model Publication No. 2-118124 are known. ing.

[0007]

[Problems to be solved by the device]

 In such a gasket 1, since the gasket portion 2 is sandwiched between the flanges and the flanges are tightened, the gasket 1 is left as it is. Therefore, the additional portion 3 is kept out of the flanges, and It will be in appearance.

In many cases, the gasket 1 of this type uses a core metal as a sealing material, and when the additional portion 3 is subjected to vibration or impact, the sealing material falls off and only the core metal is present. However, there is a problem that not only promotes the above-mentioned uncleanness, but also that there is a possibility of being injured by touching the core bar.

The present invention solves the above-mentioned problems in the conventional gasket, and there is a risk of injury due to the gasket clamped and clamped between the flanges protruding from the flanges or exposing the core metal. The purpose is to avoid the situation and to eliminate the possibility of being improper.

[0010]

[Means for Solving the Problems]

 The present invention is a gasket in which a gasket portion required for a sealing function and a grip allowance are integrated, and the gasket can be manually separated with a minimum cross section required to support the gasket portion between the gasket part and the grip allowance. It is characterized by the provision of various parts.

[0011]

[Action]

 The gasket of the present invention has a minimum cross-sectional area required to support the gasket, and has a continuous gripping margin at a manually separable portion to prevent the gasket from slipping, and after manually mounting the gasket, By separating and cutting the separable portion, the picking margin is cut off. Therefore, since there is no protruding portion between the flanges, the deterioration of the appearance is eliminated and the injury due to the core metal of the gasket is prevented.

[0012]

Embodiment An embodiment of the present invention will be described below with reference to FIG. The flange shape of this embodiment is the same as the flange 2 of FIG. 2 shown as a conventional example, and a grip margin 6 is provided at one end of a gasket portion 4 having the same shape as the flange 2 via a cut portion 5. Has been.

The cutting portion 5 is capable of supporting the gasket portion 4 and is cut into a hollow shape from both left and right sides so that the gasket portion 4 can be easily twisted off. When is a gasket material embedded in the seal material, it is preferable that the cut portion 5 has no cored bar.

However, the cut portion 5 and the grip allowance 6 may be arbitrarily set in terms of shape and installation location as long as the gasket 1 can be easily supported by sandwiching the gasket 1 between them and can be easily removed. Absent.

The gasket 1 configured as described above has the grip portion 6 and is interposed between the flanges, and the state where the gasket 1 is held is continued to prevent the gasket 1 from being displaced in position and to prevent the gap between the flanges. Tighten and securely attach the gasket 1 in place.

[0016] Thus, with respect to the gasket 1 that has been attached, the picking margin 6 is easily cut off by a cutting means such as twisting the cut portion 5, and the picking margin 6 remains between the flanges. The drop can be eliminated.

Further, by setting the cutting portion 5 at a position where there is no core metal, the cutting portion 5 can be easily cut off, and the core metal remains after the cutting and touches this to cause injury. It is possible to eliminate the improper appearance of the cored bar.

[0018]

[Effect of device]

 As described above, according to the present invention, since there is a grip margin that can support the gasket, it can be interposed between the flanges, and the flanges can be tightened while preventing the displacement of the flanges. It can be done easily and reliably at a designated place.

After the installation is completed, the separable part can be easily cut off by a means such as twisting off the manually separable part, leaving a picking margin between the flanges and sealing by vibration or the like. It is possible to prevent the core metal embedded in the gasket material from being exposed due to the falling off of the material, and to prevent the appearance from being deteriorated, and to prevent the core metal from being touched and injured.
