Description

Self-operated type water inlet and automatic stepping water saving flusher

The utility model belongs to sanitary installation, is the water saving fixtures of water closet bath with water tank.

At present, the phenomenon of wasting water that sanitary installation causes because of leaking is not only that the draining valve port is poorly sealed to be caused, and it also is the phenomenon that often occurs that water intaking valve leaks.From present patent of declaring, great majority concentrate on the improvement aspect of outfall, and the leakproof of water intaking valve does not draw attention.Closing of water intaking valve is by ball lever compacting water inlet, and for reaching sealing, the ball lever design is longer, and ball float is bigger.Its shortcoming is: the position that ball float accounts in water tank is bigger; Skew about ball lever is easy influences the keying of draining flap; Because ball lever directly compressing is closed, caulking gum is because stressed than being out of shape greatly, makes it poorly sealed and leaks; Its seal form is the compressing ferrule, easily leaks during water pressure fluctuations.In addition, draining valve leak and can not stepping flushing also be the main cause of wasting water, the special water box of the technical design of imitated foreign country is also arranged recently, but stepping washes but complex structure, and can not improving existing water tank.

The purpose of this utility model is a kind of novel self-operated type water inlet of design and automatic stepping water saving flusher, and its water intaking valve adopts the self-operated type sealing to solve the seepy question of water intaking valve, is provided with air partition chamber in the valve body; Principle of negative pressure is adopted in draining, the bath of stepping subchannel; The handle handiness, and the sanitary installation that adaptation is used at present renovates.

Self-operated type water inlet of the present utility model and automatic stepping water saving flusher are made up of water tank, water intaking valve, draining valve, gutter, handle, it is characterized in that:

Constitute the starting and stopping type sealed feed valve of relying on oneself by valve gap, valve body, sleeve pipe, water inlet pipe, valve gap is connected by screw thread or bolt type with valve body, one relief hole is arranged on the valve gap, aperture 1-3 millimeter, there is a cleansing pin at the inboard center of valve gap, place a circular spacer ring in the valve body, the barrier film flap is set on spacer ring, and there is a water supplement port in the valve body outside, and the barrier film flap is divided into lower valve chamber with valve chamber, the spacer ring bottom is that air cuts off the chamber, and delivery port is located between sleeve pipe and the water inlet pipe;

Draining valve comprises syphon, ejector, valve seat, flap, syphon one end is connected with the valve seat elbow, the other end is the water sucking mouth of control cistern water level height, inclined mouth type funnelform ejector of abnormity and inclined-plane valve seat are connected as a single entity, and outer wall is irregular arc, and the end opening of ejector is concentric with the valve seat end opening, valve seat elbow outer wall upper end is provided with a water supplement port, the bottom is connected with draining is curved, and hollow hemispherical flap one end has two brackets, on two pivot pins of extension and valve seat elbow;

Handle comprises outer spiral shell hollow bolt, nut, handle, filler ring, eccentric wheel, locking nut, rod, stepping direction board, hollow bolt is fixed on the water tank wall by nut, and an end of bolt connects filler ring and eccentric wheel, rod one end is connected with eccentric wheel, and the other end drives flap with cotton rope.

The circular spacer ring of placing in the described water intaking valve valve body has 4-8 limbers on the plane.

The described drain valve seat angle gradient is 30 °-40 °, and twice dynamic resistance muscle is arranged in the drain valve seat chamber.

Described barrier film flap is basin shape or " worker " font, and there is aperture at the center, and following valve body has 4-6 microscler weep hole, between water inlet pipe and sleeve pipe.

Described floating ball diameter is the 40-80 millimeter.

Described hollow bolt is the external screw thread formula, and an end has round edge and square boss.

The external side of described water intaking valve has a water supplement port and a delivery port.

The course of work of the present utility model is: when water tank was filled water, ball float drove ball lever and seals the water intaking valve relief hole, and the water inlet flap is closed water inlet, and drain trap is sealing state because hydraulic pressure and suction function are held on the ejector mouth; During bath, pull the stepping handle, lifting arm is mentioned flap by tether, washes, and handle rotates when the eccentric wheel rotational angle is spent less than 45, i.e. half chests water flushing, and washing water quantity is the 4.5-5 liter, produces jet when promoting, flap is closed, and forms siphon; When drawdown arrived aperture place, syphon water sucking mouth, siphon was destroyed, and flushing stops, and recovered sealing state; In draining valve work, because drawdown, ball float drives lever, open relief hole, water inlet hydraulic pressure is greater than the hydraulic pressure of uuper valve chamber, and flap rises, and begins water inlet, when water level rises to the precalculated position, close relief hole, part water enters uuper valve chamber through letting out the flap centre bore, when treating the hydraulic pressure of uuper valve chamber and lower valve chamber hydraulic balance, flap is closed water inlet, and all device recovers sealing state.As promote angle above 45 degree, and the water in the water tank is realized one case water flushing by ejector and syphon water outlet simultaneously, water intaking valve repeats said process.

Self-operated type of the present utility model water inlet and stepping water saving flusher have automatically realized that hydraulic pressure is relied on oneself to close, and have had the multi-functional of automatic ration, stepping flushing that water-saving result is remarkable.As calculating by a tame four-hole people, go to toilet for each person every day 6 times, wherein urinate for 5 times, the sanitary water amount is 31.5 liters for each person every day, shared 126 liters/day of four-player.Compare with single grade of water tank (9 liters), can save 2.7 tons in every month, 8.1 tons of everyone year water savings.Family of four can be saved 32.4 tons of water every year.Calculate by 1,000 ten thousand people as Beijing, can economize on water 8,100 ten thousand tons every year, water per ton is by 0.30 yuan of calculating, and then Beijing can save 2,430 ten thousand yuan of water rates, remarkable in economical benefits every year.
