Abstract

22,218. Ross, R. L. Oct. 13. Safety-valves.-Relates to an annular safetyvalve for steam generators. Fig. 1 is a front elevation half in section. The valve is enclosed in a casing formed of an open cylinder A screwed to a flanged ring A' which may be formed in one with the valve seat a which may have lips a'. The valve has also a tail b<2> guided by a bearing a<2> in the valve seat, or by other means. The valve and seat may be formed with or without corresponding lips. The spindle c bears upon the valve b and is guided by the sleeve c<1>. The spring or load is supported between flanged rings d, e, which form joints like ball-and-socket joints with the spindle and sleeve. A plate g screwed or otherwise connected to the end of the spindle c, covers openings b<*>, through which escaping steam passes, and acting on the plate g further increases the pressure on the valve spindle. The valve thus opens and closes more rapidly. The plate g is kept from rotating by a fin g<1> on it fitting into a slot in the ring e. By slackening the nut h the spindle can be turned by a suitable key. The spindle cannot be tampered with owing to the housing i.
