Abstract
1289237 Valves FORGES DE BELLES ONDES 19 April 1971 [21 Jan 1970] 20090/71 Heading F2V The closure member 6 of a valve is provided with a compression seal 7 and is operated by a knob 2 having an internal thread in engagement with an external thread on the valve body 1, a stack of spring washers 23 being interposed between the valve stem 8 and a bearing 20 inside the operating knob to maintain pressure on the seal 7. Leakage from the body 1 is prevented by a seal 13 between the stem and its guide 9 and a further seal 14. A frusto-conical spring washer 23a and a circlip 24 secure the knob 2 to the stem. In a modification, leakage from the body is prevented by a metallic bellows surrounding the stem and having its ends soldered, welded or brazed to the closure member and the stem guide.
