Abstract
450,336. Safety valves. CLORIUS, O. T., 6, Vesterfaelledvej, Copenhagen. March 11, 1935, No. 7576. Convention date, March 9, 1934. [Class 135] In a safety-valve construction in which the safety-valve member 5 is connected with or controls a valve 11 which closes to isolate the high-pressure side 2 and vent the low-pressure side 3 when the safety-valve 5 blows, a projection 16 on the valve casing encircles the valve 11 in its open position so as to prevent the flowing fluid from blowing or sucking it to its seat 10 before the pressure for which the which the valve 5 is set is attained. The valve 5 is loaded by a weighted lever 7 but may alternatively have a spring load. The projection 16 is formed on a closure cap 14. A piston 15 on the safety valve 5 prevents any appreciable escape of fluid before the valve 11 is clear of the projection 16. The fluid escaping past the valve 5 instead of passing directly to the atmosphere may be conducted by a pipe to a well. The Specification as open to inspection under Sect. 91 also describes a flange 17 on the member 5 against which the escaping fluid impinges to produce a high lift. This flange is shown but not described in the Specification as accepted.
