Abstract

The utility model discloses an energy-saving and directly dropping type flushing valve which is composed of a valve body, a valve cover, a water inlet pipe, a water draining pipe, a sealing element, a valve core device, and a button device. The utility model has reliable sealing and non-leaking phenomenon; a user can carry out the arbitrary pre-setting and the size of the opening of a valve mouth can be adjusted by a screw; a user can manipulate a big button and a small button to realize the selection of the washing quantity according to the requirement so as to reach the energy saving purpose; the directly dropping type flushing structure of the design has small structural size and occupation area saving.

Description

Energy-conservation vertical flushing valve

The utility model relates to a kind of delay-self-closing flushing valve.

The used flushing valve of at present general family is water tank type, its internal construction is the floating ball lever formula, this structural volume is big, and engaged position is big, with how long just not bad, water can't be regulated again, seriously have the defective of life-span weak point, seal degree difference, owing to leak, people quite feel headache, many families close without hesitation need not, become the flusher that exists in name only.

The purpose of this utility model is to avoid the defective of prior art and releases a kind of energy-conservation vertical flushing valve reliable, sturdy and durable, that the position that takes up room is little, flushing dose is adjustable that seals to society.

The utility model is achieved in that it has spool device and the pushbutton unit that is provided with the unlatching valve port in valve body, valve gap, water inlet pipe, gutter, potted component, the valve body, described spool device comprises the stepped spool with interior valve port, body cavity is separated into valve pocket and pressure chamber, have aperture on the spool, be provided with valve rod, spring and jump ring in the spool; Described pushbutton unit is provided with the open amount of valve port in the second gear control, and every grade comprises the push-button socket fastening with valve body, is provided with button spindle, spring and button over against valve rod in the seat; On gutter, be provided with simultaneously anti-siphon air vent.

Valve gap is provided with the adjustment screw that the control valve port is opened size.

The utility model is owing to be equipped with potted component on the bonding surface of each vital part, so sealing is reliable, treat that in a single day valve port close and promptly do not have drainage, valve port is opened size and can be set arbitrarily in advance by the adjustment screw user, and as requested, can handle the selection that size button realizes flushing dose, reach energy-conservation purpose, the flushing mechanism volume of vertical is little, and area occupied is economized.

Description of drawings.

Fig. 1 is the utility model structural representation.

Fig. 2 is the vertical view of Fig. 1.

Remake by above-mentioned accompanying drawing embodiment and to describe in further detail.

The valve body (7) of energy-conservation vertical flushing valve (referring to Fig. 1-2) has the water inlet pipe (1) of vertical structure, gutter (13), valve gap (9) is threaded with valve body (7), be provided with the spool device of opening valve port (2) in the valve body, he comprises the stepped spool (3) with interior valve port (14), body cavity is separated into valve pocket (15) and pressure chamber (5), spool (3) valve port (2) locates to be provided with " O " RunddichtringO, and be provided with bowl ring between valve body (7) internal chamber wall, has into water aperture (4) on the spool, also be provided with the valve rod (6) of valve port (14) in opening in the spool, reset with the jump ring (10) of spring (11) and fixing spring.

Valve body is provided with pushbutton unit, this pushbutton unit has valve port (14) open amount in the second gear control, comprise and the push-button socket (17) of valve body (7) close-fitting, be provided with button spindle (16) in the seat, with the button (19) of button close-fitting and the spring (18) that resets over against valve rod.

Gutter (13) wall is provided with the air vent (12) of anti-siphon, and the residual air in the gutter is discharged through air vent, reduces water resistance.

Valve body afterbody valve gap (9) is provided with regulates the adjustment screw (8) that valve port (2) is opened size, and adjustment screw screws in left, and valve port is opened little, otherwise the valve port unlatching is big.

The utility model also is provided with the leakproof seal circle at each bonding surface place.

The dynamic structure of this flushing valve is as follows:

Water with pressure enters valve pocket (15) through water inlet pipe (1), enter pressure chamber (5) by spool aperture (4), because spool step structure and the sectional area that is in pressure chamber part are greater than valve port (2) area, thereby the pressure that makes pressure chamber increases gradually spool is moved to the left and the self-closing valve mouth, the normal conditions valve port is in closed condition, the pressure of press water is big more, and valve port is closed tight more.

This moment is as if big (or little) button (19) of pressing over against valve rod (6), make button spindle (16) promote valve rod and cause the valve rod deflection, water in the pressure chamber (5) is just discharged through interior valve port (14), reduce pressure chamber pressure gradually, when the frictional force that adds bowl ring when pressure chamber (5) pressure is lower than valve pocket (15) pressure, automatically move right after spool (3) time-delay, open valve port (2), water is promptly discharged from gutter (13).When hand left button (19), button spindle (16) resetted under the effect of spring (18), has removed the thrust to valve rod, and valve rod promptly resets under spring action, closed interior valve port (14), and this moment, the hydraulic pressure of pressure chamber rose and close port (2) again gradually.
