With using the utility model, the urinal toilet can automatically flush in a timing mode after used without people's conscious operation. The washing time can be adjusted. Owing to making use of the potential energy of water source pressure directly and the water outlet gross pressure can change with rectangle shape, the utility model not only has small structure but also has high flushing ability and water resource saving. Otherwise, with the various operation modes, the utility model can be not only suitable for a new toilet but also suitable for the modification of a present toilet.
Description
The utility model discloses a kind of full-automatic flushing valve, be used for the flushing cleaning of opening automatically, cut off the water supply the urinal lavatory.
At present, the flusher great majority that use in the urinal lavatory adopt and manually cut-off formula, also some adopt manually open, time-delay cut-off type, but can not need the people to go consciously to operate and the device that can automatically open, wash, turn-off is also rare.Though disclose several these class devices in the Chinese patent literature, all had bigger weak point.As " CN2030629, automatically energy storage flushing device ", " CN2035366, fully-automatic sanitary water saving flushing device ", " CN2036549, lavatory with the foot-operated device of cutting off the water automatically that washes away automatically " etc., the shortcoming that has is directly not utilize source pressure; The outlet pressure straight line descends during flushing, and effectively washing time is little with the ratio of whole washing times, and promptly flushing water is efficient low; The band cistern, volume is bigger; It is non-adjustable to delay time, if need to regulate discharging quantity of water, then need change the volume of cistern.The time-delay principle of " CN2032279, a kind of automatic delayed opens and closes liquid valve " is to produce damping action by friction, so time delay part is easy to wear, time-delay is unstable, and the life-span is short; Its link rod operating mechanism is also complicated." CN2044999, urinal full-automatic flushing and water saving fixtures " are rather complicated, have cost height, shortcoming that reliability is low.
The purpose of this utility model is to provide a kind of can overcome above-mentioned shortcoming, can directly utilize source pressure potential energy, the efficient height of flushing water, structure is small and exquisite, time-delay is adjustable and the life-span is long, the flushing valve that has the full-automatic flushing function again, thereby, exempt people's trouble and provide convenience for keeping the lavatory health.
Basic principle of the present utility model is: by being arranged at the urinal other just horse block or the pedal of the pin trigger mechanism of person temporary lodging, experience the human body action of gravity, start the pin trigger mechanism, thereby driven plunger parts, make two-way valve change into closed condition by following closed condition rapidly, and keep this state.After the human body action of gravity disappeared, under the effect of the promotion of hydrodynamic force, spring force and time delay part, two-way valve slowly recovered initial closed state, and finishes the flushing to urinal in this process.On structure, the utility model mainly comprises three parts:
1, time-delay piston actuation mechanism: form by plunger shaft up and down (18,23), one way valve and the time delay part etc. that are separated by piston (19) that piston (19), sealing ring (20), spring (17), guide peg (14), loam cake (16), valve body (13) surround.Wherein one way valve comprises nonreturn valve core (22), limits limit Cheng Huan (21), the annular groove (7) of its stroke and goes into circulation road (9c); Time delay part comprises metering pin valve (12), sealing ring (11), the aperture (9a) that communicates with lower piston chamber (23), needle-valve chamber (10) and and goes into the aperture (9b) that circulation road (9c) communicates.On loam cake (16), be provided with the pore (15) of proper number, upper piston chamber (18) is communicated with ambient atmosphere.
2, two-way valve: comprise two-way spool (27), valve rod (25), sealing ring (6), upper valve base (26), lower valve base (5), valve pocket (30), lower cover (29), sealing mat (28), entrance cavity (24) etc.Valve rod (26) upper end links to each other with piston (19); Two-way spool (27) leaves and closes to what (5) two sections dynamic processes of lower valve base need move from upper valve base (26) and only accounts for about 15% of whole process apart from summation, be that two-way spool (27) is in valve pocket (30) in about 85% the motion process, the circulation passage shape of the two formation is basic identical, thereby can guarantee in this section motion process, outlet pressure is basicly stable, and the rectangular shape of stagnation pressure (equaling dynamic pressure+static pressure) of exit water is changed.
3, pin trigger mechanism: two kinds of forms are arranged.A kind of is that liquid is handled form, and a kind of is that soft rope is handled form.The structure that liquid is handled form comprises the horse block (4) of flanged pin (2), liquid capsule (3) (liquid wherein is housed, and generally is water), the conduit (8) of band liquid feeding mouth (not drawing among the figure).Horse block (4) is pressed on the liquid capsule (3), and liquid capsule (3) places hole (1); Conduit (8) is guided to D and is gone into circulation road (9c) by liquid capsule (3) outlet C and joins.When adopting this manipulation form, the rise of piston (19) is by hydraulic pressure; Medium by time delay part is liquid (generally being water).The structure that soft rope is handled form comprises pedal (39), spring (38), soft cable core (33), soft noose (35) and fixing cutting ferrule (34,36) etc. thereof, soft cable core (33) two ends by draw-barring (32,37) respectively with piston element on guide peg (14) and pedal (39) link, pedal (39) connects by fulcrum (40) and ground are moving.When adopting this maneuverability pattern, the pulling force that the rise of piston is transmitted by soft rope, and what enter lower piston chamber (23) from passage (9c) is air, so the medium of delaying time is an air.Above-mentioned horse block (4) and pedal (39) all are arranged at just person temporary lodging, urinal both sides.
When guaranteeing that two-way spool (27) is in up and down closed condition, sealing force is enough, from designing the mobile range that guarantees piston (19) stroke greater than two-way spool, when promptly two-way spool (27) was in up and down closed condition hermetically, piston (19) also had removable surplus.
In order to make two-way spool (27) from closed condition is rapid as far as possible to closing state procedure down, thereby make the water that flows out in this process few as far as possible, the time of selecting this process is less than 1 second, maximum opening, the annular groove (7) by selecting nonreturn valve core (22) and go into the size of circulation road (9c), the parameters such as number of pore (15) guarantee.
The utility model is compared with aforesaid full-automatic flushing device, and except that structure was small and exquisite, significant advantage was:
1, can directly utilize source pressure potential energy.At two-way spool (27) when upper valve base (26) falls, water from the water source directly flows to outlet by A through entrance cavity (24), valve pocket (30), this economizes hydraulic energy than the form of section that is flowed out flushing by water storage tank, and stagnation pressure (the equaling dynamic pressure+static pressure) height of outlet flushing water helps flushing.
2, time-delay is adjustable reliable.Height by metering pin valve (12), just can change the restrictor ring area that needle-valve (12) head and aperture (9b) form, thereby change releasing the time of the middle fluid (liquid or gas) in lower piston chamber (23), reach and regulate the purpose that washing time changes washing water quantity.Because the metering pin valve that employing is made medium with fluid is made time delay part, so time-delay is reliable and stable.
3, the efficient height of flushing water is saved water.Because of when the stagnation pressure that goes out saliva is lower than certain value, flushing water has just lost rinse capability, so in whole washing times, the stagnation pressure that goes out saliva is in the ratio of above time of virtual value and whole washing times, has just represented the efficient of flushing water.Fig. 3, Fig. 4 represented respectively the device of band water storage tank form and the variation diagram that the utility model goes out the saliva stagnation pressure (wherein among Fig. 4 with maximum stagnation pressure value P
mThe time of the straight line portion that line is mutually neat accounts for more than 85% of total time).Obviously, at maximum stagnation pressure value P
mIdentical, the export pipeline system is just the same (is effective stagnation pressure value P
xIdentical), washing time (t
g-t
k) under the situation about equating, the efficient η t=t of flushing water
x/ (t
g-t
k) (t in the formula
xBe that stagnation pressure P is in P
xAbove time, i.e. effective washing time) by Fig. 4 calculate value be greater than the value of Fig. 3.That is to say the efficient height of flushing water of the present utility model,, the advantage of saving water is arranged promptly so under same service condition, the utility model can reduce washing water quantity.
The utility model is described in further detail below in conjunction with example.
Example 1: see Fig. 1.This is that a pin trigger mechanism is the example that liquid is handled form.Among the figure, the access water pipe links from B and A with valve respectively, and horse block (4) is arranged at just person temporary lodging, urinal both sides, and dress is water in the liquid capsule (3), and the circulation road (9c) of going on conduit (8) and the valve body (13) joins.Two-way spool (27) is in closed condition down usually.When just person goes on just position, horse block (4) is just because of being subjected to the human body action of gravity, squeezed fluid capsule (3), water wherein by C to D through conduit (8), go into circulation road (9c), annular groove (7), push nonreturn valve core (22) open and enter lower piston chamber (23), promote piston (19) and overcome various resistances and rise, and drive two-way spool (27) lift off a seat (5) through valve rod (25), the pass is to upper valve base (26), and this process is rapidly, is not more than for 1 second.In this very short time, can flow out low amounts of water from outlet, the effect that this just in time plays moistening urinal helps formal flushing.Before just person did not leave just the position, two-way valve was in closed condition always.When just person is just intact leave just the position after, the stressed disappearance of horse block (4), the hydraulic pressure in lower piston chamber (23) descends greatly, under the pressure effect of piston (19) water in spring (17), entrance cavity (24), just begins decline.But because nonreturn valve core (22) at this moment recovers closed condition, water in the lower piston chamber (23) can not flow back to liquid capsule (3) rapidly, only may pass through aperture (9a), needle-valve chamber (10), the throttling of the little circumferential weld that forms through metering pin valve (12) head and aperture (9b) and releasing, so be slowly, so two-way spool (27) leaves upper valve base (26) and needs certain hour to closing in lower valve base (5), is exactly formal washing time during this period of time.It can change by the adjusting to metering pin valve (12) aperture, thereby selects the best washing time that can rinse well under regular situation and can not waste water.Because the shaped design of valve pocket (30) and spool (27), in two-way spool (27) dropping process, except that just leaving upper valve base (26) and soon the two sections short processes about lower valve base (5), in middle nearly 85% the process, the stagnation pressure of exit water remains on the maximum value substantially, and flushing water keeps big pressure washing substantially in other words.Washing time just can shorten like this, and the single water supply volume just can reduce.Close when lower valve base (5) when two-way spool (27), flushing finishes, thereby finishes once flush cycle automatically.Being provided with the pore (15) of proper number on loam cake (16), is in order to guarantee piston (19) in the back and forth movement process, and the gas turnover in upper piston chamber (18) is unobstructed, makes piston (19) motion flexibly.Loam cake (16) is anchored on valve body (13) with screw, and lower cover (29) tightly is coupled to valve body (13) (screw and bolt all specifically do not draw among the figure) with bolt.
Example 2: see Fig. 2.This is that a pin trigger mechanism is the example that soft rope is handled form.It and example 1 are basic identical in main body (31) part of valve.Main difference is the pulling force that the lifting of piston (19) is transmitted by the soft cable core (33) that is connected on the guide peg (14); By what go into that circulation road (9c) enters lower piston chamber (23) is not water but air, and the time-delay medium is an air.Its course of work is: be in the urinal both sides just the pedal of person temporary lodging (39) after the action of gravity that is subjected to human body, following pressing spring (38), through draw-barring (37) tension in soft cable core (33).Because soft noose (35) and fixedly the soft cable system that forms of cutting ferrule (34,36) and soft cable core (33) have the function that curve transmits power, so this pulling force just can be through draw-barring (32) biography to guide peg (14), thereby piston (19) is raised.After the stressed disappearance of pedal (39), it just resets down in spring (38) effect, and guide peg (14) and piston (19) just descend because of suffered lifting force disappearance, and other course of work, principle are identical with example 1.
Example 1 is suitable for newly-built lavatory most, but also can install through existing urinal both sides, lavatory ground is constructed a little; The installation of example 2 must be to foundation construction, so be suitable for the repacking of existing lavatory flushing system most.
Most of part of the present utility model can be with nonmetal, and as making such as rigid plastics and rubber, not only structure is light and handy, and cost is low, and durability is good.
