A drain valve inner core tube clamping device

Abstract

The invention discloses a drain valve core tube clamping device. In the water level rising state, a complete-drainage floating buoy deflects to a core tube, a complete-drainage retainer is close to the core tube, meanwhile, a half-drainage floating buoy lifts a half-drainage adjusting lever to rise, the half-drainage adjusting lever drives a half-drainage support to swing close to the core tube, a half-drainage retainer is close to the core tube, and a push and ejection portion of the half-drainage adjusting lever applies acting force to a lock bar mechanism to realize interlocking; in the water level lowering state, the complete-drainage floating buoy deviates from a core tube, the complete-drainage retainer deviates from the core tube, meanwhile, the half-drainage floating buoy lowers to drive the half-drainage adjusting lever to descend, the half-drainage adjusting lever drives the half-drainage support to swing away from the core tube, the half-drainage retainer deviates from the core tube, a squeezing portion of the half-drainage adjusting lever applies acting force to the lock bar mechanism to realize unlocking. When a drainage button is pressed for a long time, precise drainage can be realized, and water resources are saved.

Description

technical field [0001] The invention relates to the technical field of drainage valves, in particular to a locking device for an inner core tube of a drainage valve. Background technique [0002] In the prior art, there is a drain valve that roughly includes a body, a half row of buttons, a full row of buttons, a drive rod, a half row of floating buckets, a full row of floating buckets, a half row of fulcrums, a full row of fulcrums, an inner core tube and a water sealing sheet; Among them, the half row of floating barrels, the full row of floating barrels and the inner core tube are assembled in the body; one end of the driving rod is connected to the upper end of the inner core tube, and the other end of the driving rod is connected to the half row of buttons and the full row of buttons. The row of buttons is push-button or wire-controlled. Pressing the half-row or full row of buttons will make the drive rod drive the inner core tube to move in different strokes. The half...

Problems solved by technology

[0005] The half row of buttons and the full row of buttons of the drain valve directly drive the inner core tube to move in different strokes through the drive rod. Therefore, when users who are accustomed to long pressing the half row of buttons or the full row of buttons, the inner core tube is always lifted. state, the water sealing piece at the lower end of the inner core tube is separated from the drain outlet at the lower end of the body and is always in a draining state, which wastes water resources and cannot achieve accurate drainage
