Description

The water saving flushing valve

The utility model relates to a kind of flushing valve, relates in particular to a kind of button type water saving flushing valve.

The ight soil syringe that uses in the existing lavatory mostly is high level cistern, lower water box, screw switch formula and foot-operated several.Often because of phenomenons such as leaking does not sternly appear in valve closing, lacks of water, backguy is fragile for higher/lower cistern, water supply volume inconvenience control; Screw switch can not automatic switch, uses inconveniently, unhygienic, meets the situation of the cutting off the water accident of often metalling run out that supplies water again; Shortcomings such as pedals type valve is fragile, and the existence unlatching is ineffective and be not closed completely.A kind of push button valve is also arranged now, leak, operate phenomenons such as ineffective because of existing some problems to be prone on the structure.

The purpose of this utility model provides a kind of water saving flushing valve of novel push button, it is according to fluid mechanics principle, utilize in the running water pipe self hydraulic pressure to carry out work fully, solved shortcomings such as present flushing utensil valve switch is ineffective, poorly sealed, fragile, reach the purpose of water saving simultaneously.

The purpose of this utility model realizes by following structure: it is made up of valve body, valve gap, spool, seal gasket, drainage channel, button, gland, and the spool bottom surface is a Baltimore groove, and seal gasket is embedded in the Baltimore groove; Form a cavity between valve body, valve gap and the spool, in adorn the big glued membrane of a lid shape; Wear aperture nail in the spool, seal gasket and big glued membrane are fixed in the spool two ends; The button lower end connects a triangle screw, between button and the triangle screw little glued membrane is housed.

The Baltimore groove of spool bottom surface closely cooperates the seal gasket and the spool that are embedded in the groove, has not only strengthened sealing, makes end face smooth simultaneously, is beneficial to the cooperation of associated part.

The utility model adopts the hydrodynamics law of connected vessels, and a container is when air-tight state, and the water level height is identical, and the size of two ends holding capacity is then decided by the area size at two ends on the work plane.

In the utility model, spool is housed in the valve body, spool one end is a seal gasket, the other end is big glued membrane, because the area of big glued membrane moves spool by the different holding capacity in two ends, the water inlet of valve-off greater than the area of seal gasket.When needing Open valve, press button, promote the triangle screw, the mediation drainage channel, the water in the cavity between valve body, valve gap, the spool is drained, and the cavity internal pressure reduces, spool displacement, valve open, current pass through.

Further specify structure of the present utility model and behavior in service below by embodiment shown in the drawings.

Accompanying drawing is the structural representation of the utility model embodiment.

The water saving flushing valve that present embodiment provided, form by valve body (1), valve gap (6), spool (4), seal gasket (3), drainage channel (13), button (10), gland (11), spool (4) bottom surface is a Baltimore groove, and seal gasket (3) is embedded in the Baltimore groove, has strengthened sealing effectiveness.Form a cavity (12) between valve body (1), valve gap (6) and the spool (4), in adorn a lid big glued membrane of shape (5), aperture nail (2) passes from center spool, with seal gasket (3) and greatly glued membrane (5) be fixed in the spool two ends.Button (10) lower end connects a triangle screw (8), adorns a little glued membrane (9) between button and the triangle screw; Triangle screw (8) root is equipped with cushion rubber (7), and the bottom is welded with a cleansing pin that passes aperture nail (2).

Do not apply at this device under the situation of external force, current enter cavity (12) by aperture nail (2), because the lid big glued membrane of shape (5) is stressed stressed greater than seal gasket (3), spool (4) is withstood by big glued membrane (5), makes valve be closed condition.In the time of need opening valve, press button (10), promote triangle screw (8), the water in the cavity (12) flows into cavity between valve gap and the little glued membrane (9) by triangle screw (8) and space between the valve gap (6), and passes through drainage channel (13) outflow.Because the water in the cavity (12) is drained, act on the hydraulic pressure that hydraulic pressure on the big glued membrane (5) is lower than the suffered valve water inlet of seal gasket (3), spool (4) is moved to big glued membrane (5) one ends, valve is opened, and current pass through.Stop to press button, triangle screw (8) is blocked the passage between valve gap and the little glued membrane again, and the hydraulic pressure that acts in the cavity (12) on the big glued membrane makes spool move to seal gasket (3) one ends, and valve is promptly closed.

Cleansing pin in the aperture nail (2) moves around, and can prevent the dirty aperture that stops up of sealing.

Use this to install the time that button is pressed in how many decisions of visual water supply volume, generally press 1-2 can feed water 4-5 second in second, close automatically after the flushing, so water-saving result is remarkable.

The utlity model has following advantage:

1. reasonable in design, compact conformation, volume is little, and part is few, and no spring part uses the longevity Life is long.

Easy to use, laborsaving, water-saving result is remarkable.

3. installation and maintenance are easy, use water quality wide.

Claims (2)

1. a water saving flushing valve is made up of valve body (1), valve gap (6), spool (4), seal gasket (3), drainage channel (13), button (10), gland (11), it is characterized in that:

A. spool (4) bottom surface is a Baltimore groove, and seal gasket (3) is embedded in the Baltimore groove;

B. form a cavity (12) between valve body (1), valve gap (6) and the spool (4), in adorn a lid big glued membrane of shape (5);

C. wear aperture nail (2) in the spool (4), seal gasket (3) and big glued membrane (5) are fixed in spool (4) two ends;

D. button (10) lower end connects a triangle screw (8), and little glued membrane (9) is housed between button and the triangle screw.

2. water saving flushing valve according to claim 1 is characterized in that: triangle screw (8) root is adorned a cushion rubber (7), and end face is welded with a cleansing pin that passes aperture nail (2).
