Description
【発明の詳細な説明】
この発明は、配管の静電気による腐食を防ぐ為まだは、
機器の地上からの帯電防止をする為のスリーブである。[Detailed Description of the Invention] This invention is intended to prevent corrosion of piping due to static electricity.
This sleeve is used to prevent static electricity from being applied to equipment from the ground.
従来、配管において静電気による腐食によってパイプに
穴が明く事がたびたびあった。In the past, holes often formed in pipes due to corrosion caused by static electricity.
従来品は図によって説明すると、フッソ樹脂性スリーブ

ー■の組合せによるものがあるが、配管現場において取
付は誤りで電気絶縁出来ていないことがたびたびある。Conventional products include a combination of a fluorine resin sleeve 0 and an epoxy resin or phenolic resin washer (2), but they are often installed incorrectly at piping sites and electrical insulation is not achieved.
まだ、配管用７ランヂまたは機器の取付けにはボールト
用穴が多く明いており、１つの取付は誤りでも電気絶縁
が出来ない欠点がある。There are still many holes for vaults in the 7-land piping or equipment installation, and there is a drawback that electrical insulation cannot be achieved even if one installation is incorrect.
この発明はこの欠点を除く為にされたものである。This invention was made to eliminate this drawback.
それを配管用フランヂについて図によって説明すると、

ー■でフランヂを止める。これによってフランヂ■方向
とフランヂ■方向の電気を遮断するものである。To explain this with a diagram of a piping flange,
Insert the insulator sleeve into the metal vault ■, attach the electrically insulating backing ■ to the connection between the metal flanges ■ and ■, and secure the flanges with the metal nuts ■ and metal washers ■. This cuts off the electricity in the flange direction (1) and flange (2) direction.
パイプ■よりの電気はフランヂ■よりワッシャー■、ナ

同じ作用がある。なお、絶縁体スリーブには次のような
ものがある。Electricity in the direction of the pipe (phase) is transmitted through the 7 land (■), but is blocked by the sleeve (■). This has the same effect when connecting devices. The following types of insulator sleeves are available:
（イ）絶縁体がフッソ樹脂であるスリーブ。(a) Sleeve whose insulator is fluorocarbon resin.
（ロ）絶縁体がセラミックであるスリーブ。(b) A sleeve whose insulator is ceramic.
