<p>PCT No. PCT/DK90/00216 Sec. 371 Date Mar. 31, 1992 Sec. 102(e) Date Mar. 31, 1992 PCT Filed Aug. 23, 1990 PCT Pub. No. WO91/02694 PCT Pub. Date Mar. 7, 1991.A valve arrangement is so adapted that it can be used for a transportable container (1) for storing and distribution of a liquid under pressure from a propellant gas. The arrangement comprises a stub (2) secured in an opening upwardly in the container (1) and a double valve (12) with both a gas and a liquid passage (33, 35). The valve (12) substantially consists of a valve housing (3), which can be detachably mounted in the stub (2), as well as a riser pipe part (15), which is mounted co-axially with an upper reception area in the valve housing (3) and which can be displaced from an upper closed valve position to a lower open valve position against the pressure of a spring (10). The riser pipe part (15) can moreover be displaced additionally a distance downwardly from the lower open valve position to a lower bottom position. Further, the riser pipe part (15) mounts an obliquely downwardly and outwardly protruding finger (42) with a lower free end part (44 ), which is so spaced from the top and axis of the riser pipe part (15) that the valve (12) can only be dismounted completely in or in the vicinity of the bottom position of the riser pipe part (15). This prevents damage which might occur if unauthorized persons should try to dismount the valve (12) before the gas pressure in the container (1) has been completely relieved.</p> |
