FILLING VALVE Russian patent published in 2006 - IPC F16K31/24 E03D1/30 

FIELD: water power engineering.

SUBSTANCE: filling valve comprises housing with inlet and outlet branch pipes and cylindrical seat, flexible valving member that cooperates with the seat, lid, lever, tie, and float. The cylindrical seat is made in the housing to define the ring space around it. The space is in communication with the inlet branch pipe. The lid is set in the housing and its bottom is provided with the nozzle projecting outward. The outer side of the lid is provided with the cylindrical flange. The flexible valving member is clamped inside the housing over periphery by means of the lid. The space of the lid is separated from the ring space of the housing by means of the the flexible valving member and is in communication with the space around the through nozzle and to the ring space of the housing through the orifice. The lever is mounted for permitting rotation with respect to the lid by means of the cantilever. One of the ends of the lever is provided with the gate. The other end is kinematically connected with the tie. The tie is provided with a float for permitting movement with respect to the ring. The tank filled with fluid receives the sleeve. The bottom of the sleeve is provided with the opening that receives the floating valve for communication of the inner space of the sleeve with the tank when the fluid is discharged from the tanks. The float is mounted inside the sleeve for permitting vertical motion. The housing is provided with two-step ring collar. The collar is located at the level of the cylindrical seat. The L-shaped pillar is secured to the lid. The vertical large side of the pillar is provided with the sleeve. The sleeve has rectangular passage arranged along its side. The pillar passes through the passage for permitting the sleeve to move with respect to the second cantilever of the housing. The seats of their pillars are mutually perpendicular and provided with the long side along or counter to the inlet branch pipe of the housing.

EFFECT: enhanced reliability.
