Abstract
1336446 Valves V LANGEN [trading as LANGEN & CO] 11 Dec 1970 [22 Dec 1969] 59072/70 Heading F2V In a safety valve 1, the flow path between the pressurized port 6 and the drain 7 is controlled by a valve member 12 which is formed integrally with a varying diameter stem 9, 10, 12a, the stem having a narrow passage 23 extending therethrough. In operation, the valve member is biased to the position shown by a spring 15 the force of which is adjustable by a handle 17, 19, the handle interior containing a pressure gauge 22 which communicates via the passage 23 in the stem with a further, transverse passage 24 likewise in the stem. Lifting of valve member 12 occurs when the force of pressure fluid within a chamber 2 and acting on the end of stem part 9 exceeds the force of spring 15, the chamber 2 being in communication with the pressurized duct 6 via the stem passage 23. Figs. 2 and 3, not shown, depict modifications of the combined relief valve and pressure gauge arrangement.
