面に形成せしめたガスケツト材料である。 Here, the term "composite gasket material" refers to a gasket material that can be easily formed into a desired gasket shape by forming an elastic sealing material not only on one side but also on both sides of a sheet-like base material. The elastic seal material is a gasket material in which a honeycomb structured elastic embossed pattern is formed on both sides of a sheet-like base material.
ガスケツト材料は通常、例えば配管フランジ継
手、その他各種部材のパツキング材として広く利

が、これらはいずれもシール性に劣り、漏洩防止
が不充分である。 Gasket materials have conventionally been made by impregnating non-woven fabric with synthetic resin, forming a flexible film on the surface of a sheet-like base material, or attaching a mesh-like elastic sealing material to one side of a sheet-like base material. Although other gasket materials are known, they all have poor sealing properties and are insufficient in preventing leakage.
このようにガスケツトを介して密封してもな
お、流体が密封した箇所から漏れる原因として次
の二つのことが考えられる。 There are two possible reasons why fluid may still leak from the sealed area even though the gasket is sealed in this manner.

ンジ、３は流体を示す。(A) Penetration leak As shown in Figure 1, fluid leaks in the direction of the arrow through the capillary tube of gasket 1 itself, especially in the case of gaskets made of fibers or porous gaskets. This phenomenon is likely to occur. In addition, in FIG. 1, 2 represents a flange, and 3 represents a fluid.
(B) 接面漏れ
これは第２図示のようにガスケツト１とフラ
ンジ２面とも接面で矢印方向に漏洩するもの
で、フランジ面の歪み、仕上精度、ガスケツト
の材質などに起因する。(B) Leakage from the contact surface As shown in the second figure, this leakage occurs in the direction of the arrow at the contact surfaces of the gasket 1 and the flange 2, and is caused by distortion of the flange surface, finishing accuracy, the material of the gasket, etc.
本考案の目的は前述の浸透漏れおよび接面漏れ
の両方を防止してシール性を充分に向上しうるシ
ール性の高い複合ガスケツト材料を提供すること
にある。 An object of the present invention is to provide a composite gasket material with high sealing properties that can sufficiently improve sealing properties by preventing both the above-mentioned permeation leakage and contact surface leakage.

手部分の接面漏れを完全に防止する。 The composite gasket material thus obtained is punched into any shape to obtain a gasket of a desired shape, for example, a composite gasket for a flange joint (not shown). When this is clamped between the flanges and tightened with bolts, the raised patterns on both the front and back sides of the gasket form independent and discontinuous sections between the flanges, which exhibit a packing action and provide a sealing effect. . Moreover, in this invention, the raised patterns on both sides of the gasket are formed so that they match through the sheet-like base material, so the pressure-receiving area for tightening the gasket and seating it on the flange is small (the surface area of the raised pattern receives the force). ), it also has perfect elastic sealing properties, exhibits high sealing performance with low tightening surface pressure, and completely prevents leakage from the contact surface of the joint.
