Description

A drain valve inner core tube clamping device

technical field

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

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-row limit protrusions and the full-row limit protrusions are correspondingly provided with a half-row fulcrum in linkage with the half-row of floating buckets, and a full-row fulcrum is set in linkage with the full-row of floats.

When the half-row is flushing, press the half-row button, and the inner core tube is lifted upwards through the drive rod until the half-row limit protrusion is against the half-row fulcrum that is linked to the half-row floating bucket. At this time, the inner core tube is restricted. When the water level drops to the half row of floating barrels, the half row of floating barrels loses buoyancy and the half row of fulcrums deflects under the action of gravity, that is, the half row of fulcrums is stretched out, and the inner core When the pipe loses contact, it falls back down and resets, and the water sealing sheet falls back to the drain outlet to complete half a row of flushing.

When the whole row is flushed, press the button of the whole row, and the inner core tube is lifted upwards through the driving rod until the full row limit protrusion is against the full row fulcrum of the full row of floating buckets, at this time the inner core tube is limited, The water sealing sheet is lifted to realize flushing. When the water level drops to the full row of floating barrels, the full row of floating barrels loses buoyancy and the full row of fulcrums deflects under the action of gravity, that is, the full row of fulcrums is stretched out, and the inner core tube loses When it abuts, it falls back and resets, and the water sealing sheet falls back to the drain outlet to complete the flushing of the whole row.

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 sheet 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.

Therefore, even if the whole row of buttons is pressed for a long time, the inner core tube 2 can fall back in time, and the water sealing sheet 21 can block the water outlet in time to realize accurate drainage.

After draining, the inner core tube 2 seals the water outlet 21 in time to seal the drain on the body 1 to achieve precise drainage, as shown in Figures 27 to 29.

The above descriptions are only preferred embodiments of the present invention, and are not limitations on the design of this case. All equivalent changes made according to the key points of the design of this case fall within the scope of protection of this case.
