Abstract

PURPOSE:To prevent solidification of an O-ring at a low temperature by providing a heater wire on a flange surface in a flange of a low-temperature device. CONSTITUTION:A heater wire 5 is arranged in a groove provided on a flange surface 4 or a flange is pinched as a sandwich structure. When the flange connection is switched, a current is fed with the heater wire 5 and a power supply 6 to heat the flange. Thereby, a solidified O-ring 1 is softened, moisture frozen on the surface is melted, the O-ring is made fully compressible, and the vacuum leakage can be reduced.

The ring 1 is solidified and water freezes on the 7 flange surface 4. If the O-ring is not sufficiently softened and the ice on the flange surface 4 is melted and wiped clean before reconnecting it to another flange, the O-ring 1 will not be compressed sufficiently and a vacuum failure will occur after connection. do. Conventional low-humidity devices with a seven-lunge structure do not have a heating device, and are heated with a dryer each time the connection is changed.

〔発明の構成と実施例〕[Structure and embodiments of the invention]

本発明は上記の点に鑑みなされた加熱機構付フランジで
、その特徴はフランジ面にヒーター線を設けたことであ
る。The present invention is a flange with a heating mechanism that was created in view of the above points, and its feature is that a heater wire is provided on the flange surface.

〔発明の効果〕〔Effect of the invention〕

本発明の加熱機構付７ランジの効果は （１）　　ヒーター電源をＯＮするだけでフランジが一
様に加熱されるので、フランジ接続替え時に一々ドライ
ヤーで加熱する必要がなくなり、手軽な操作でフランジ
接続替えができる。The effects of the 7-lunge with heating mechanism of the present invention are (1) The flange is heated uniformly just by turning on the heater power, so there is no need to heat each flange with a dryer when changing the flange connection, and the flange can be connected with a simple operation. Can be replaced.

（２）　　フランジが冷却され、固化されることがなく
なるので、Ｏリングの寿命が長くなる。(2) Since the flange is cooled and does not solidify, the life of the O-ring is extended.

（３）　　フランジの０リングが固化することなく弾性
のある状態で使用するため、低温装置の真空もれが少な
くなる。(3) Since the O-ring of the flange is used in an elastic state without solidifying, vacuum leakage of the low temperature equipment is reduced.
