In the accompanying drawings, double (double or dual) flowing water flushers according to the present invention are presented with.Preferably, the punching Device is washed to be embedded in wall.Six during a large amount of buttons 4 protrude in the outside of the wall and allow user to select to rinse are public The substantial amounts of flushing risen.A small amount of buttons 5 also protrude in the outside of the wall and allow user to select to rinse in correspondence A small amount of flushings in a large amount of parts, such as three liters.Spring 6 and 7 is synergistically installed with the button to be pressed by user The latter is brought back into initial position after pressure.

The amount (a small amount of or a large amount of) of the water of flusher is discharged by the flusher opening connected with water supplying pipe road.It is described Flusher opening is closed by gate 20.The opening passes through time-delay valve 21 by the larger or less closing of the gate (control valve) controls.

Time-delay valve 21 is controlled to include control delay chamber 22, the volume of control delay chamber 22 can be according to the motion of upper plate 23 Change, upper plate 23 demarcate the delay chamber in the upside of itself.Spring is installed to back up upper plate 23.

The upper plate 23 is connected to gate 20 to coordinate with the latter, so as to (pass through water in the upper position of the upper plate Kept in the effect of the equivalent pressure of the pressure and opposite side of side and spring), the gate closes the flusher opening, when When in the lower position of the upper plate, the unclosed flusher opening of the gate simultaneously allows current to pass through.

Time-delay valve 21 inside the water supplying pipe road 24 between water supply opening 25 and flusher opening 26, open by flusher Mouth 26 is closed by gate.

The upper plate 23 will control delay chamber 22 to demarcate, so rather than in a manner of being fully sealed.The water of pipeline can It is delayed in control in chamber 22 with the bottom horizontal flow sheet of the peripheral edge of upper plate 23.

Normal position (flusher does not rinse i.e. during normal position), opening 26 closed by gate 20 and The delay chamber fills up water, pipeline be under the hydraulic pressure of water distribution networks and above the upper plate with following hydraulic pressure phase Together, therefore the upper plate is located at upper position.

The motion of upper plate 23 passes through fully or partly via the control delay chamber of the emptying exhaust-valve 21 of pipeline 28 22 and control.

Control delay chamber 22 is emptied by the emptying pipeline 28 of gate 20 with given amount, is wishing gate 20 for a long time In the case of its position outside is rested on to realize the big discharge capacity of the flusher, it is defined as largely, wishing gate 20 In the case of being maintained to short period on the outside of its position with the less discharge capacity of flusher, it is defined as a small amount of.This is given Period during amount is opened by pipeline determines.If substantial amounts of water is drained, be arranged to that upper plate 23 uses is penetrating into institute State and rise period of return under the influence of the water in the delay chamber at the edge of upper plate and become big, therefore the opening period of gate 20 Between period become big, therefore the flusher discharges substantial amounts of water.If a small amount of water will be drained, it is arranged to upper plate 23 What is used rises the period of return under the influence of the water in penetrating into the control delay chamber at the edge of the upper plate Diminish, therefore the period during the opening of gate 20 diminishes, therefore the flusher discharges a small amount of water.

The fully or partly emptying of control delay chamber 22 causes the decline of upper plate 23 (due to the water on upper plate 23 Pressure becomes to be above the pressure in the chamber, and spring is adjusted to no longer to resist the decline of upper plate in this case), and Therefore this causes gate 20 to leave its position and opens flusher opening 26, to allow the discharge of water.

For filling up control delay chamber 22 again, gate 20 little by little rises its position of return, until 23 liang of upper plate The hydraulic pressure of side is equal and during the period of the position of gate closing opening 26, the discharge of water is effective.

The period for the filling that control delay chamber 22 uses after emptying limits the water flow velocity of flusher.If on described Plate has reduced very big height (this can be adjusted by the amount of the water of emptying) after emptying, and that fills in a corresponding way holds The continuous time is very long and the amount of flushing is very big, if upper plate has reduced lower height, (adjustment depends on water emptying Amount), the duration filled in a corresponding way is shorter and the amount of flushing is smaller.

In order to control or drive control delay chamber 22 emptying and upper plate and gate movement, flusher control dress Put and further comprise driving time-delay valve 27 (driving time-delay valve 27 also includes driving delay chamber).Driving time-delay valve 27 is arranged to beat Open the emptying pipeline 28 of control delay chamber 22 and close it.

Driving time-delay valve 27 or driver include valve rod 8, and the movement of valve rod 8 causes the drive of the driving time-delay valve The opening of the pipeline 29 of dynamic delay chamber.Had been described above according to being equal to for the original that is cooperated between upper plate 23 and gate 20 Reason, the time that driving the emptying of the driving delay chamber of time-delay valve causes the gate opening for emptying pipeline 28 sufficient prolong to drive When valve 27 driving delay chamber fill up again.The emptying amount of driving delay chamber is directly proportional to the path of valve rod 8, and the latter is in itself Button depending on the selection between a small amount of buttons and a large amount of buttons.

Blade is installed between a small amount of and a large amount of buttons and driving stem.The blade can revolve on end pivotal point 10 Turn ground installation.The blade includes pin 11 and pin 12, and pin 11 is used for the valve stem contacts with a large amount of buttons 4, pin 12 be used for it is a small amount of The valve stem contacts of button 5.Pin 11 is than pin 12 closer to the pivotal point.

The pipeline 29 in time-delay valve 27 is driven to cause the driving delay chamber of driving time-delay valve 27 and outside and evacuated tube Road 28 is in fluid communication, and for discharging the water for coming from control delay chamber 22 in opening 26, while is discharged greatly by opening 26 Amount or a small amount of flushing waters.

Therefore, finally, the mobile route of driving stem 8 is depended on by the flushing dose of outlet opening.

When user is pressed against on a large amount of button, as shown in fig. 7, the valve rod of button 4 starts squeeze pin 11, cause institute State that blade rotates on its pivotal point 10 and the blade starts to press the valve rod 8 of the trigger valve.Moved corresponding to valve rod 8 Path causes the emptying of the driving delay chamber of the driving time-delay valve, and causes the opening for emptying pipeline 28, then causes The emptying of control delay chamber 22, and the discharge of big flushing dose is ultimately resulted in, it is followed by being used to fill up control delay chamber again The time of room 22, filling up again with the driving delay chamber of followed by described driving time-delay valve is closed in emptying pipeline 28.

Adjustment block 13 is arranged in the blade, and can be relative to the blade slides.Therefore, it is possible to along figure towards left or Person moves described piece towards the direction on the right side, will the described piece of pivotal point 10 taken to closer to or further from the blade.The tune Monoblock 13 includes the inclination skewback acted on according to the position of pin 12 on the position of pin 12.Shown position in figure 3, pin 12 squeeze It is pressed in described piece of horizontal lower.In the centre position, as shown in figure 5, pin 12 and described piece of inclination (inclined or Sloped) portion contacts.Finally, in maximum position, as shown in figure 1, pin 12 and the described piece of top contact in adjustment part.Therefore, According to the corresponding position relative to pin 12 of adjustment block, pin 12 is close or away from a small amount of buttons 5.It is leaned on must be nearer (described Maximum position), the squeezing action that button 5 is applied on the blade is stronger, and blade will be caused to be revolved on a large scale on its pivotal point Turn, and the valve rod mobile route of driver is bigger under the extruding of blade.On the contrary, the pin is more remote from button 5, the blade exists Rotation during button 5 works is smaller, and the translation of the driving stem of driver is smaller.Therefore, the movement of the valve rod of driver Path is directly proportional to the emptying amount of the driving delay chamber of driving time-delay valve 27, therefore empties control delay chamber with emptying pipeline 28 Period during room 22 is directly proportional, and is therefore located at gate 20 outside its position and causes the time during the opening of opening 26 Section is directly proportional.Similar, the period during opening 26 is opened determines flushing dose.

Therefore, can be by accurately adjusting small-sized flushing only in relation to block described in blade slides according to the system The amount of device.Specifically, as shown in the side view in accompanying drawing, mark and otch can be set, can be easily adjusted tune Slip in the translation of monoblock.
