Abstract

The utility model relates to a sectional drain valve switch fixed on a drain valve in a toilet water tank. A unit body in the switch has different gas guiding hole size, thus the discharging water is varied by the different gas flow through the gas hole. One or more unit body is arranged on the switch, user can reach an aim of saving water by sectional drainage according to requirement.

Description

The district drainage threshold switch

Affiliated technical field

The utility model relates to a kind of district drainage threshold switch that is fixed on the tank for excrement pan internal drainage valve, cell cube air guide aperture is not of uniform size on its switch, displacement is changed by the gas flow of pore is different thereupon, one or several cell cubes are set on the switch, the user as required, can carry out district drainage, reach the water saving purpose.

Background technology

Existing draining valve adopts gravity principle to finish the draining task mostly, is subjected to structural limitations, and displacement is fixed substantially, and it is loaded down with trivial details that whole system seems, poor reliability, though the displacement that has can be regulated, tolerance is narrow, the draining repeatable accuracy is low, is difficult for regulating unfavorable water saving voluntarily.

Summary of the invention

The utility model is that a kind of district drainage threshold switch will be provided, utilize the throughput of switch element body, the control displacement, make the structure of a whole set of drainage system seem simple, adjustable, the switch element body combination that differs if any several such throughputs on the draining valve, the user selects different discharge values according to different needs, realizes water saving.

The skill flitch case that its technical problem that solves the utility model adopts is: the district drainage threshold switch that is made of a switch element body at least, its switch element body is by switch body, valve, the valve switch bar, pore is adjusted piece and is formed, switch body is two holes on the cavity structure, be equipped with the adjustment piece on the hole, be block, can make to change the size in aperture, form the fine setting hole, this fine setting hole communicates with draining valve, and another hole is provided with valve, this door closes, open and controlled by the valve switch bar, the valve switch bar has an end and switch body to be hinge to be connected, its can link one or more valve closes and closes, now the district drainage threshold switch being fixed on the hydrocone type draining valve is example: they are work like this, the hydrocone type draining valve inserts two groups of switch element bodies, with two groups of switch fine setting apertures, arrange into not of uniform size, by the valve switch bar two valves being in one opens, a closed condition, fine setting hole big valve is shut, and little opens, and depresses with the syphon that external force will be contained on the hydrocone type draining valve in the water tank, water enters syphon simultaneously topmost, gas is extruded rapidly by two valves in the pipe, a valve of closing (unidirectional exhaust), and gas resets after discharging immediately, atmosphere can not reflux, another valve is opened, and gas is directly arranged to atmosphere, forms negative pressure in the syphon, siphon produces, draining begins, because the fine setting hole is less relatively, gas backstreaming speed is slower, up to siphon destructive, draining stops, and shuts otherwise finely tune the little valve in hole, and big opens, gas backstreaming speeds up, siphon destructive, the draining premature termination forms two sections different displacement like this, increase user selection, realize water saving.

The specific embodiment

Among Fig. 1, a switch element body is by switch body (4), valve (2), valve switch bar (1), pore is adjusted piece (3) formation, switch body (4) is cavity structure, on two holes are arranged, be equipped with the block piece (3) of adjusting on the hole, be block, can adjust the size in aperture, form the fine setting hole, this fine setting hole communicates with draining valve, another hole is provided with movable valve (2), this door closes, open and be subjected to valve switch bar (1) control, valve switch bar (1) has an end to be hinge with switch body (4) to be connected, its can link different conditions of one or more valves (2) Push And Release, form a cover switch thus. now the district drainage threshold switch being used in the hydrocone type draining valve is example: see the sectional view that Fig. 2 is made up of two switch element bodies, wherein the fine setting aperture of two cell cubes arranges into not of uniform size, valve switch bar (1) is installed in and makes two valve (2-a, 2) there is one to open on the fastening position all the time, from Fig. 2 finding valve (2) is to open, adjusting piece (3) is adjusted to the hole less, and valve (2-a) is closed, adjusting piece (3-a) is adjusted to the aperture bigger, in this state, now this is fixed on the hydrocone type draining valve the switch cell cube, as shown in Figure 3, this moment with external force (P) to the syphon of hydrocone type draining valve exert pressure (shown in Figure 4), water enters syphon simultaneously topmost, syphon is along with water enters, gas is by the instantaneous valve (2-a) of extruding in fine setting hole in the pipe, valve (2-a) can only unidirectional exhaust, gas has been arranged the back and has been resetted immediately, atmosphere can not reflux, another valve (2) is opened, gas is directly arranged to atmosphere, the instant negative pressure that forms in the syphon, siphon produces, when draining begins, atmosphere is by in valve (2) the backflow syphon, because this fine setting hole is less relatively, the atmosphere back-flow velocity is slower, up to siphon is destroyed, draining stops (shown in Figure 5), if switch lever (1) is rotated an angle, from see air outlet valve (2 as Fig. 6,2-a) state is compared with Fig. 2, be in inversion state, former shutting of opening, that shuts opens, after now again syphon being pressed down, equally also can siphon produce, but gas backstreaming speeds up, siphon accelerates the failure, draining premature termination (Fig. 7), this forms two sections different displacement, and the user can select different displacement according to needs at that time.

Claims

1. district drainage threshold switch, at least constitute by a switch element body, described switch element body comprises switch body (4) and movable valve (2), it is characterized in that the switch body (4) in the switch element body is cavity structure, on two holes are arranged, one communicates with draining valve, and another hole is provided with above-mentioned movable valve (2).

2. according to the described district drainage threshold switch of claim 1, it is characterized in that the described hole that communicates with draining valve, be equipped with the change aperture and be block adjustment piece (3).
