Abstract
281,156. Baxter, A. April 9, 1927. Feedwater, heating.-A valve for diverting feedwater from an economizer direct to the boiler on breakage of a tube comprises a casing 1, double-beat valves 5. 7 on stem 8 bearing a piston 9 and normally spring-pressed to close the passage from the inlet to the economizer connection 3. and to open that leading direct to the steam generator at 4. The space 11 beneath the piston 9 is in communication with the passage 3 to the economizer by a passage 13 and so long as the economizer is pressuretight as in normal working, leakage of water through a port 12 will cause the piston 9 to be kept in a raised position and the feed will pass to the economizer. On a fall in pressure in the economizer the piston, and the connected valves will fall and a way opened direct to the boiler. Specification 198,723 is referred to.
