ADJUSTMENT AND TESTING STAND FOR SPRINKLER UNITS, NOZZLES AND SURFACE SPRINKLER UNITS Russian patent published in 1996 - IPC

FIELD: mechanical engineering, in particular, evaluation of qualitative and quantitative characteristics of sprinkler units. SUBSTANCE: stand has pump unit, water vessel covered with planking, pressure pipeline, pressure meters, movable device with pressure hose 11 and stand pipe 12 with union 13 fixed from below, coupling 14 mounted on top and adapted for connecting sprinkler unit to be tested, two joined drums 19 and 20. U-shaped arced member is detachably fixed to drum 20. U-shaped member is provided with sleeve 29, where second pipe 12b with coupling 14 is mounted for sliding. Sleeve 14 is adapted for connecting sprinkler unit or nozzle 15b to be tested, with sprinkler unit of nozzle being turned through 180 deg relative to standard position. To adjust and test sprinkler units, U-shaped frame 28 in assembly with sleeve 29, pipe 12b, union 13, coupling 14 are removed and object to be tested is introduced into upper drum 20 through opening of ring 26. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 cl, 4 dwg
