The flushing amount can be determined according to the mission time of the closet, thereby automatic time-delay flushing is realized. The utility model is energy-saving, water-saving, simple in structure, low in cost, and suitable for all toilet seats.

Description

A kind of automatic flushing valve

Technical field

The utility model relates to a kind of tank for excrement pan automatic flushing valve, the flushing valve of the automatic stepping time-delay of particularly a kind of energy-saving and water-saving flushing.

Background technology

Present known automatic flushing valve is divided into electronic type and mechanical type two big classes, the cost height of electronic type, power consumption, the difficult popularization; Mechanical type always has complicated link gear, and controlling organization is bigger, need be arranged on the closet appearance, is unfavorable for the closet overall appearance, and mostly is one-shot, unfavorable water saving.

Summary of the invention

In order to overcome the deficiency of above-mentioned automatic flushing closestool flushing valve, the utility model discloses a kind of automatic flushing valve, not power consumption, simple in structure, cost is low, automatically stepping flushing.

The technical scheme that the utility model technical solution problem is adopted is: described automatic flushing valve, comprise water closet, water tank, water intaking valve, controlling organization, it is characterized in that by flush port, the bath valve block, bleed off pipe, guiding trestle, self-locking mechanism, floating drum connects composition in proper order, the valve block that covers on the flush port is fixedly arranged in the bleed off pipe lower end, bleed off pipe places in the guiding trestle center sleeve that is buckled in flush port Flange Plane relevant position, can move vertically, the bleed off pipe upper end has been installed with floating drum, the floating drum end opening is concordant with valve block, and guide pipe is provided with lever locking device, lockup arm and controller tangle.

The beneficial effects of the utility model are, not power consumption, and stepping time-delay flushing automatically, simple in structure, cost is low, is applicable to all toilet seat water tanks.

Description of drawings

Among the figure: flush port (1) bath valve block (2) bleed off pipe (3) floating drum (4) leading truck (5) self-locking mechanism (6) controller (7) control valve (8) control knob (9) water intaking valve (10) water tank (11)

Accompanying drawing is the novel flushing valve structural representation of this reality.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Described automatic flushing valve, flush port, valve block, bleed off pipe, leading truck, self-locking mechanism, floating drum connect in proper order.Valve block is made up of glued membrane and bossed plastic valve plate, glued membrane outer and valve block outer are fixed, valve block has through hole, gapped between the diaphragm, glued membrane is topped on flush port, and be fixedly arranged in the bleed off pipe lower surface entirely, bleed off pipe places in the guide thimble at the leading truck center that is buckled on the flush port Flange Plane, can move axially, the bleed off pipe upper end has been installed with floating drum, the floating drum end opening is concordant with the bath valve block, and radius is greater than the valve block radius, should make float buoyancy with under the water level definitely greater than the level pressure on the bath valve block.Guide pipe is provided with lever-type self-locking mechanism, and the half slot on lock head and the overflow tube wall joins, self-locking arm with place the controller on the leading truck to tangle, mechanical brake is often locked; Control valve places the chamber pot flushing water road to communicate with the control knob of water channel upper surface through hole, and the connection of the controller on leading truck water intaking valve pressure water supply, borrows the hydraulic drives controller, Closet ring seat Coverage Control button, and the ring soffit contacts with control knob top.

Valve block was closed flush port when the utility model was static, and water intaking valve makes water tank only advance 3L water, the mechanical brake self-locking, and the buoyancy that floating drum produces can not discharge, and flushing valve keeps closed condition, and this design has overcome the problem of mistake discharging quantity of water, water saving.

When the people used closet to go to the lavatory, the pressure that puts on Closet ring seat had triggered controller through control knob, and controller enters SBR; Use and finish the pressure disappearance, controller action, release, under buoyancy, flushing valve rises and opens, and replys static state after bath is finished again.

When the people uses closet to have a bowel movement, water intaking valve one set service time after, can intake once more and end until 6L side.The flushing valve course of work as previously mentioned with go to the lavatory identically, go round and begin again, finish automatic stepping time-delay flushing.

Described automatic flushing valve should keep when the identical water level certain power poor for the result of use that guarantees makes floating drum, valve block, so related data should meet following formula: (calculate slightly in the bleed off pipe cross section)

If: floating drum height=h, valve block water level=H

Floating drum radius=R valve block radius=r

Then: π R ²H＞π r ²H R＞r

6L water flushing urine is not used in the not electricity consumption of described automatic flushing valve, energy-conservation, water saving, simple in structure, cost is low, is fit to all water closets, very easily promote.
