Title
(EN) Float valve and utilization system
Abstract
(EN)

A closure member (64) is mounted at the lower end of a draw tube (14) for pivotal movement between an open position (FIG. 4) and a closed position (FIG. 3). The closure member (64) includes a first side part (68) having a lower outer surface (80) which contacts an upwardly facing first valve seat (76) when the closure members (64) is in a closed position. The closure member (64) includes a second side part (70) which extends laterally outwardly from the pivot axis (66). Side part (70) includes an upper outer surface (82) which contacts a second valve seat (78) when the closure member (64) is in a closed position. A first part (88) of a float arm (94) is connected to the second part (70) of the closure member (64). Float arm part (88) extends downwardly from side part (70) to a lower end connection (92). A coil spring (106) is interconnected between the lower end (92) of arm part (88) and the lower end (98) of arm part (96). A buoyant float body (102) is connected to the outer end of arm part (96).
