【考案の詳細な説明】
本考案は、分割管継手などに好適に使用される
ガスケツトの改良に関する。[Detailed Description of the Invention] The present invention relates to an improvement in a gasket suitable for use in split pipe joints and the like.
管継手本体を複数部分に分割し、管体の接続時
にはこの分割された部分を継ぎ合わせて一つの管
継手本体を形成するようにしたいわゆる分割型管
継手が比較的大径管などの接続に多用されている
が、このような分割型管継手用として開発された
ガスケツトは未だになく、弾性に富むゴム材や合
成樹脂材でリング状に形成された一般の管継手用
のガスケツトが使用されている。 The so-called split-type pipe fitting, in which the pipe fitting body is divided into multiple parts and the divided parts are joined together to form a single pipe fitting body when connecting pipes, is suitable for connecting relatively large diameter pipes. Although they are widely used, there are still no gaskets developed for such split-type pipe fittings, and gaskets for general pipe fittings made of highly elastic rubber or synthetic resin materials are used. There is.

スケツトに比べ寿命を著しく縮めているのが現状
である。 For this reason, when the fluid pressure inside the joint increases, the gasket may protrude from the gap created at the joint of the pipe joint, reducing the airtightness of the joint, or causing local deformation of the part that contacts the joint. Gaskets for split-type pipe fittings are not suitable for general gaskets, which can lead to accelerated deterioration and also cause problems such as damage to the gaskets by the edges of split pipe joints when connecting pipe bodies. Currently, the lifespan of gaskets is significantly shorter than that of gaskets for pipe fittings.

にすぐれ、しかも装着の容易な分割型管継手用ガ
スケツトを提供しようとするものである。 This invention was developed in view of these circumstances, and when a gasket is attached to a split pipe joint,
The gasket body is characterized by a thin reinforcing plate that extends from the outer circumferential surface to the side circumferential surface of the gasket body at a portion corresponding to the joint joint portion of the gasket body, thereby improving airtightness and deterioration resistance. An object of the present invention is to provide a gasket for a split type pipe joint that is excellent in performance and easy to install.
以下に、添付図面と共に、本考案の一実施例を

強板２…を被着したもので、補強板２の被着され
る部分は、分割継手の継ぎ合わせ部分の数によつ
て規定される。 An embodiment of the present invention will be described below with reference to the accompanying drawings.As shown in the figures, the gasket of the present invention will form a joint part of the joint when fitted into a split type pipe fitting (not shown). Thin reinforcing plates 2 are attached to corresponding parts, and the parts to which the reinforcing plates 2 are attached are defined by the number of joint parts of the split joint.
第１図及び第２図に示すものは４分割型管継手
に適用したもので、補強板３はガスケツト本体１
の外周面より側周面に延びるように被着されてい
る。 The one shown in Figures 1 and 2 is applied to a 4-split pipe joint, in which the reinforcing plate 3 is attached to the gasket body 1.
It is attached so as to extend from the outer peripheral surface to the side peripheral surface.
ガスケツト本体１の素材とその形状は任意であ
り、従来公知のガスケツトのすべてのものが採択
されることはいうまでもない。 The material and shape of the gasket body 1 are arbitrary, and it goes without saying that all conventionally known gaskets can be used.
補強板３は、比較的軟質で耐蝕性に優れた薄肉
金属などが望ましく、例えば黄銅、ステンレスな
どの中から適宜採択される。 The reinforcing plate 3 is preferably made of a thin metal that is relatively soft and has excellent corrosion resistance, and is appropriately selected from brass, stainless steel, etc., for example.
本考案ガスケツトは、以上のような構成である

される。そのため、叙述したはみ出しに伴う気密
性の低下やガスケツト本体の局部的な変形が未然
に防止され、ガスケツトの耐用寿命が向上する。 Since the gasket of the present invention has the above-mentioned configuration, if it is used by fitting it into a split type pipe joint, the gasket body can be removed from the gap created at the joint of the joint when the gas pressure inside the joint increases. If the outer circumferential surface tries to protrude outward, or even if the side circumferential surface of the gasket body tries to protrude from the gap to both sides when the joint is tightened and the gasket body is compressed, the protrusion will be caused by the reinforcing plate. This is reliably prevented by the back-up action and the shape-retaining action (maintaining the original shape) of the gasket body. Therefore, the deterioration in airtightness and local deformation of the gasket body due to the protrusion described above are prevented, and the service life of the gasket is improved.

易にするなどの効果がある。 Furthermore, since the joint part of the joint and the gasket body do not come into direct contact, the gasket is not damaged by the edges of each divided part, and at the same time, it improves sliding, making it easier to fit the gasket into the joint. There are effects such as
