FIELD: manufacturing technology.SUBSTANCE: invention relates to double seat float valve and is intended for automation of process of filling tanks with working fluids in oil or fuel tank design during preflight preparation of aircraft. Double seat float valve comprises body with mounting seats, where lever with float is mounted on axis of rotation, connected with stem to displace axially by two valves interacting with mounting seats. Float is fixed relative to lever on axis of rotation. In area of axis of rotation on adjacent to each other elements of float and lever is angular division unit in form of through holes of the same diameter arranged regularly on identical circles with different pitch on mating surfaces and mutual angular location of the float retainer relative to lever, installed inside holes coinciding during float rotation relative to lever.EFFECT: simplified adjustment of tank filling level with working fluid and reduces cycle of aircraft preflight preparation.1 cl, 1 dwg |
