A kind of quick acting supercharging tank for excrement pan inlet valve

The utility model is a kind of inlet valve mechanism of automatic control toilet cistern water level.Especially show the tank for excrement pan inlet valve that adjustment disk, supercharging valve block, annular filter chamber, the quick acting mechanism of water level height form by the band pointer.

At present, the tank for excrement pan inlet valve of selling on the market, mainly contain float-ball type, floating-tube type, water pressing three major types type, now doing one with regard to above-mentioned series products analyzes: a class of float-ball type, use amount maximum, promptly adopt the ball float of the about 12cm of diameter, utilize water level to rise, hold up ball float, rotate through fulcrum by the lever that connects on the ball float and to oppress water intake, reach the purpose of closing water intake.The ball float of this series products because of being adopted, volume is especially big, can not be general, lever is long, adopts the shape of changing, and existing also in use product is most early with malfunctioning, causes the very billow at water source useless.Floating-tube type: hold up floating drum by the water level rising, lifting interlock small lever control one cover of floating drum is carried out the supercharging device of closing water intake by pressure principle, its deficiency is that volume is big, the cistern water level regulation range is little, supercharging device stops up easily, last source capsule road comes water flow hour, and is out of control easily.Water pressing: with reference to external product production, the malfunctioning reason of its product maximum is that water intake stops up, and causes whole functional to lose efficacy, and secondly exhaust port is difficult to guarantee that exhaust is unimpeded when mounted, in case exhaust port is blocked, water intake just can't be closed.

The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, and a kind of quick acting supercharging tank for excrement pan inlet valve is provided.For achieving the above object, solution of the present utility model is in an outward appearance shows the valve body of sealing, one cover pressure is set stores quick acting mechanism, deal with the supercharging device at low pressure water source, solve water quality inferiority and filtrating equipment that results in blockage and the driver chuck adjusting water level device that has the pointer demonstration.Because said apparatus has been arranged, make this inlet valve can be at low pressure area, water source, high pressure region, contain in the water tank of the high area, water source of sand, iron rust and impurity and extra-high-speed, special specification partially and use.Designated water level is easy, correct, and noise is low, specious, volume is little.

The utility model is further described with embodiment below in conjunction with accompanying drawing 1.

Accompanying drawing 1 is the utility model embodiment's a sectional view.

Quick acting supercharging tank for excrement pan inlet valve of the present utility model as shown in Figure 1, the inlet valve main body (12) that can be installed on water tank, connecting tube water source and other mechanism can be installed, valve pocket part in inlet valve main body (12), hydraulic pressure bowl (6) is installed, play valve block (9), the valve spring (8) of pressurization, the annular filter chamber (10) that the water source that leads to hydraulic pressure cavity (15) is filtered reaches anti-siphon valve (11), valve ball (34).Top in inlet valve main body (12) connects lever (16) through balance pivot (3), lever (16) is gone up by diaphragm seal (2) is arranged, through lever suspension hook (24) cylinder lever connecting rod (25), connect corrugated plate (29) by pull bar (25), be fixed on the inlet valve main body (12) by trim ring (28).Working the adjustment disk (1) of regulating water level is installed on the inlet valve main body (12), screw rod on the adjustment disk (1) screws in the adjusting slider (18) of band pointer, hook extension spring (21) by of adjusting slider (18), the other end of extension spring (21) connects depression bar (23), and depression bar (23) connects on the inlet valve main body (12) by pressing plate fulcrum (27).Hold bar (19) hold bar fulcrum (17), (20) act on respectively lever (16), depression bar (23) in the middle of partly.The shell (22) that plays protection and decorating action is closed above mechanism, with water tank the installation seal ring (13) that seals is installed, and works the installation nut (4) that installs and fixes usefulness etc. and has constituted this inlet valve mechanism.

Now be described in detail with regard to each mechanism's actual working state: as the water of certain pressure by water inlet (36), back down valve ball (34) and enter anti-siphon valve (11) after, be divided into two the tunnel, one the tunnel backs down valve block (9) through boost port (30), compression valve spring (8), (26) back down hydraulic pressure bowl (6) through the main passage again, flow into water tank by water outlet (7).Cause has been provided with valve spring (8), the valve block (9) of pressurization on boost port (30), so, for from the small flow of water inlet (36), the water source of low pressure, just at first guaranteed the work water source of hydraulic pressure cavity (15).Some through holes (32) above another Lu Jingfang siphon valve (11) flow into ringwise annular filter chamber (10) and obtain filtering, and stop impurity, flow into hydraulic pressure cavity (15) and flow-off (4) by hydraulic channel (5) again.Along with the accumulation of water in water tank of being flowed out by water outlet (7), cistern water level rises, and the suffered depth of water pressure of corrugated plate (29) also rises along with water level and increases simultaneously.Because the pulling force of extension spring (21) is delivered to hold to remake on the bar (19) by depression bar (23) and is used for lever (16).At this moment, the lever of installing by balance pivot (3) (16) is subjected to two power, one is held bar fulcrum (20) by extension spring (21) by what depression bar (23) was gone up the center, hold bar (19), hold bar fulcrum (17) and act on the hypotenuse supporting force of lever (16), because of balance pivot (3), hold bar fulcrum (17), (20) not on same straight line, show triangle, so lever (16) obtains the upwards power of lifting, the size of this power, by the rotation of adjustment disk (1) to adjusting slider (18), change the position of adjusting slider (18), thereby change the pulling force of the suffered extension spring of depression bar (23) (21), this pulling force is by holding bar fulcrum (20), (17) be delivered on the lever (16), therefore rotate adjustment disk (1) also just change lever (16) to lifting power.Play the effect that limits height of water level.Another power is exactly the displacement that hydraulic pressure produced that corrugated plate (29) is subjected to, and this displacement is input on the lever suspension hook (24) through pull bar (25), and effect lever (16) makes lever (16) obtain a downward pressure.Because corrugated plate is subjected to hydraulic pressure to produce displacement, the air in the air cavity (31) is oppressed, and (33), exhaust port (35) are communicated with atmosphere through the exhaust passage, do not bring resistance.Continuous rising along with water level, the suffered downward power of lever (16) is also increasing, when this power one and the lifting power that makes progress more than or equal to lever (16), lever (16) presses down fast, along with moving down of lever (16), balance pivot (3), hold bar fulcrum (17), (20) three forces tend to same straight line, just the lifting power that makes progress of lever (16) also trends towards zero, this is that the suffered water pressure of corrugated plate (29) is by pull bar (25), lever suspension hook (24), all act on lever (16), act on the suffered lifting power of lever (16) and need not low disappearing.Because diaphragm seal (2) is subjected to the drive that lever (16) presses down, be that diaphragm seal (2) can rapidly, effectively seal flow-off (4), like this, former water source through hydraulic channel (5), flow-off (4), can only flow into hydraulic pressure cavity (15), use pressure principle, hydraulic pressure bowl (6) is expanded, sealing main passage (26) reaches the purpose that inlet valve is closed automatically.Otherwise, when cistern water level descends, corrugated plate (29) loses the water tank water pressure and restores to the original state, drive lever (16) and rise, the lifting power that comes from extension spring (21) restores to the original state rapidly, and flow-off (4) is open-minded, hydraulic pressure cavity (15) decompression, be subjected to intake pressure, back down hydraulic pressure bowl (6), enter new round water inlet state.

The utility model compared with prior art has following advantage:

1, adopt pressure to store fast reaction mechanism, it is correct that cistern water level is set, and water level can The accent scope is big. Eliminate the phenomenon of closing of water inlet vacation in the existing product.

2, adopt separately along separate routes, the water source that enters hydraulic pressure cavity is filtered, thereby thoroughly eliminate the blocking phenomenon of this class inlet valve.

3, tackle the function of increasing pressure at low-pressure water source area and small flow water source, change out-of-control phenomenon.

4, change the channel position of exhaust port, solved the phenomenon that major part that product of the same type occurs installing can not normally be used.

5, volume is little, aesthetic in appearance, can be suitable for all size, and the water tank of shape is installed.
