Description

Delay valve without piston

(1) technical field:

What the present invention relates to is use in toilet delay-self-closing washing valve.

(2) background technique:

Existing delay self-closing valve, common structure, the flap of sealing valve port is made piston-like, one end sealing valve port, the other end can slide in a cylinder chamber, a damping hole is arranged in the cylinder chamber or lean on the casing wall gap to communicate with feedwater, there is an aperture to communicate on the piston with waste pipe, aperture sealing when not washing by water, be full of in the cylinder chamber water and with equate to hydraulic pressure, flap is pushed against on valve port.Need only the of short duration aperture of opening during bath, water is by pressure release in the cylinder chamber, and piston is boosted by water pressure, and valve is opened.Aperture or the water filling in the cylinder chamber of casing wall sulculus simultaneously promotes piston and moves down, and time-delay is close port extremely again, and its shortcoming is that structure is complicated, the cost height, and easily leak, button or valve handle need artificial trickle cleaning, inconvenient maintenance.

(3) summary of the invention;

The objective of the invention is to float, and with the compression of aqueous vapor pad, discharge and change the time-delay volume, replace former piston flap and finish normally closed, unlatching, delay-self-closing by the concavo-convex of maincenter leather cup.Tap water washed " drops " valve handle automatically and then cancels the seal arrangement of conventional valve handle, button when another object of the present invention was to wash one's hands, and above-mentioned purpose of the present invention is to realize like this.Its formation comprises: the spherical or abnormal valve body that valve gap and valve seat are formed, the maincenter leather cup, the decompression mechanism of "T"-shaped valve rod, described valve seat is water inlet, the drain opening valve seat, the inner edge of laying for the maincenter leather cup by the valve seat setting is " L " step circular port seat and establishes the draining valve port in described hole its planar central of seat, described draining valve port periphery " U " shape groove in the form of a ring connects from water inlet, the maincenter bowl of institute's art is a disk glue spare, its limit portion is ripple ring-type buffer edge, planar central is established a pressure release circular orifices, the "T"-shaped shape valve rod that drips will pass through the aperture to the valve seat drain opening, offset from center position, described maincenter leather cup plane rivet clasp one damping hole is chewed ring-type " U " the shape groove of corresponding valve seat water inlet, chew at described damping hole, its hole heart penetrates the pin that quivers of an activity, form water or air chamber in the described special-shaped valve gap, be solidified as a whole with valve seat, and compress sealing maincenter leather cup edge and low hydraulic pressure spring is installed is constituted.

Working principle of the present invention is as follows:

Smooth when the maincenter leather cup in the draining valve port, be normally closed shape, when not washing by water, the sluicing aperture at maincenter leather cup center is by "T"-shaped Decompression valves rod seal.The indoor water of certain value and the pressurized air on top, aqueous vapor chamber of being filled with of valve gap abnormity aqueous vapor, its pressure with equate to hydraulic pressure, by water pressure self-closing, because the effective function area does not wait, the maincenter leather cup of making is tight against on the draining valve port, and hydraulic pressure is high more, seals tight more, and when low hydraulic pressure supplies water, then by low hydraulic pressure spring compensation sealing valve port.Only need the "T"-shaped pressure release valve rod of of short duration shake-up valve body below during unlatching, any direction makes valve rod swing a small angle, the pressure release aperture is water outlet, this pressure relief opening communicates with draining, consider the practicability of "T"-shaped pressure release valve rod, " drops " conical valve handle good hand touch, more attractive in appearance is processed in pressure release valve rod below.The water of abnormity valve gap aqueous vapor chamber is released and is lost pressure, the pressurized gas on top, aqueous vapor chamber discharges at once and occupies space, whole aqueous vapor chamber, aqueous vapor is recovered normal pressure, and at this moment, the two sides of maincenter leather cup exists pressure difference, be subjected to power to hydraulic pressure, the maincenter leather cup overcomes the effect of low hydraulic pressure spring, and the projection of floating upward is equivalent to flap open, draining, and clean the shape valve handle that drips.Simultaneously, feedwater is chewed through the damping hole of maincenter leather cup side, and slowly to the water filling of aqueous vapor chamber, indoor aqueous vapor is slowly compressed, and after time-delay reached predetermined value, hydraulic pressure continued the anti-maincenter leather cup that pushes away, and utilizes hydraulic pressure to be close to the draining valve port to closing automatically again, has become operating mode one time.

The present invention compared with prior art has following advantage:

One, the cylinder cavity of having cancelled traditional piston time-delay mechanism and having made of quality material, height, Seiko skill, thus structure is extremely simple, reliable, Manufacturing material is more extensive, metal, plastics all can, and reduce cost significantly.

Two, it is concavo-convex to adopt the maincenter leather cup to float, water pressure self-closing, and seal element is few, has solved fundamentally that former piston is not washed by water by card or a difficult problem such as the instability of delaying time, and seal the more reliable mechanical wear of having exempted basically, and serviceability doubles.

Three, underslung " drops " valve handle can be multi-faceted touch unlatchings, wash one's hands more conveniently, and the science that also meets is washed one's hands the water saving custom, avoids the waste of water resources.

Four, the shape valve handle that drips is located at drain opening and reaches self-cleaning function, the special health of washing one's hands, and thing finishes contact-making switch again, avoids bacterial cross-infection.
