Abstract
The utility model relates to a cistern flushing device with an adjustable water displacement according to the needs, comprising a water container, a ball cock, a push-button type checking-valve, a hydraulic piston valve and its connected pipes. The opening time and the delayed closing time of the hydraulic piston valve in the water container are controlled by a push-button type checking-valve directly so that the user can control the delayed flushing time and the flushing water amount each time according to the need of the flushed objects to achieve the purpose of efficient utilization of water quantity, economy of water consumption and waste avoiding. The utility model has the characteristics of reasonable structure, reliable action, convenient operation and no leakage, and can be widely apply to the water flushing container of the toilet with a high position or a low position.
Description
The utility model relates to a kind of Cistern flushing device.Specifically, it is a kind of Cistern flushing device of forming by water tank, float valve, button stop valve and hydraulic piston type valve and interconnective pipeline thereof, it is characterized in that with a kind of that by valve seat, spool, valve core piston, piston cylinder the hydraulic piston type valve that seal disc, water inlet pipe, gutter are formed replaces the water discharging valve in the wc flushing cistern (as lavatory pan Cistern flushing device) in the prior art.
Water discharging valve majority in the Cistern flushing device in the prior art drives pull bar control cistern water-discharging plug envelope (or valve) with knob and realizes opening and closing.This draining valve starting torque is big, is difficult for resetting, and leaks easily, and displacement also is not easy control, and the waste water yield is big.
The purpose of this utility model, provide a kind of can control on demand washing water quantity, rational in infrastructure, processing performance good, reliable in action, easy to operate, water-tight, be suitable for the Cistern flushing device of popularization.
Realize by the hydraulic piston type valve opening in the button stop valve control water tank and the time of time-delay closing for this.The hydraulic piston type valve also can be made up of at piston cylinder and the middle spool that move up and down of valve seat etc. valve seat, piston cylinder and middle doing by drainage channel.Spool top is contained in the piston cylinder, has done piston on it, and the spool bottom is contained in the valve seat, and seal disc is equipped with in its lower end; The piston cylinder bottom is provided with the water inlet pipe that is connected with the gutter of button stop valve; The relation that the gap or in the mode of damping hole keep of the cavity that piston cylinder and valve core piston form below by control piston and piston cylinder communicates with atmosphere; Perforate communicates with water tank liquid around the valve seat.When the button stop valve is opened, tap water enters the piston cylinder bottom of hydraulic piston type valve by the gutter of button stop valve, the promotion piston makes simultaneously on the seal disc of spool together with its lower end and moves, therefore make it lose sealing function, valve open, water in the water tank washes through gutter by valve seat; When the button stop valve was closed, spool constantly descended under deadweight and descent waterflow effect, the liquid of (below piston) in the piston cylinder, will be from the gap between piston and the piston cylinder or damping hole row be excluded, reset up to seal disc, the closed valve seat outfall, water tank just stops flushing.
In fact what of water yield discharging in the water tank are depended on the height that valve core piston is pushed to a certain extent, have determined the seal spool dish from being opened to the required time of valve cut-off state that returns to thus, that is the time length of so-called " Slow Close " process.
The height that spool is pushed to is realized by control button stop valve.When pressing button, stop valve is opening, and tap water can flow into the hydraulic piston type valve by the gutter of button stop valve, promotes valve core piston and rises; When stopping to press button, stop valve is closed condition, stops to supply water to the hydraulic piston type valve, and valve core piston stops to rise.Therefore, the height that the piston of the said hydraulic piston type valve in front rises can be pressed the time length of button and controlled by the operator.The operator can control washing water quantity on demand according to the flushing object, effectively utilizes the water yield thereby reach, the purpose of avoiding waste.
Other some characteristics of the utility model will be illustrated further by the narration of following example.
Fig. 1 is that the hydraulic piston type valve shaft is to sectional view.
Fig. 2 is a lavatory pan Cistern flushing device floor map.
Hydraulic piston type valve as shown in Figure 1 mainly is made up of valve seat (1), spool (2), valve core piston (3), piston cylinder (4), seal disc (5), water inlet pipe (6) and gutter (7), when pressure water flows into piston cylinder (4) by water inlet pipe (6), just can promote valve core piston (3) spool (2) is moved up together with seal disc (5), the liquid in the water tank just can flow into closet by valve seat (1) and gutter (7) and wash; When water inlet pipe (7) stops into water, spool (2) constantly descends under the effect of deadweight and descent waterflow, meanwhile, liquid in the cavity (8) that the following and piston cylinder (4) of valve core piston (3) forms will be excluded from gap or the damping hole between valve core piston (3) and the piston cylinder (4), set back up to seal spool dish (5), valve closing, water tank stop the draining flushing.
Lavatory pan Cistern flushing device as shown in Figure 2 is by water inlet pipe (9), float valve (10), button stop valve (11), hydraulic piston type valve (12) and water tank (13) and interconnective pipeline thereof are formed, when pressing button stop valve (11), tap water just can flow into hydraulic piston type valve (12) promotion valve core piston (3) by stop valve valve (11) makes hydraulic piston type valve (12) be opening, washes; When stopping to press button, stop to supply water to hydraulic piston type valve (12), spool (2) constantly descends under the effect of deadweight and descent waterflow, closes fully up to valve, stops till the flushing.
Claims (2)
1, a kind of by water tank, float valve, the Cistern flushing device that button stop valve and hydraulic piston type valve and interconnective pipeline thereof are formed, it is characterized in that by valve seat (1), spool (2), valve core piston (3), piston cylinder (4), seal disc (5), water inlet pipe (6), the hydraulic piston type valve (12) that gutter (7) is formed, the spool (2) that a centre is done drainage channel and can be moved up and down in the middle of piston cylinder (4) and valve seat (1) is housed in hydraulic piston type valve (12), the top of spool (2) is contained in the piston cylinder (4), has done valve core piston (3) on it; The bottom of spool (2) is contained in the valve seat (1), and seal disc (5) is equipped with in its lower end.
2,, it is characterized in that cavity (8) that the following and piston cylinder (4) of valve core piston (3) forms is by gap or damping hole and the atmosphere maintenance relation of communicating between valve core piston (3) and the piston cylinder (4) according to claim 1 hydraulic piston type valve (12).
