Abstract
The utility model relates to a pneumatic flushing valve for a toilet cistern. Air conveyed into an air chamber can put pressure on a guide rod, the guide rod can drive an air chamber via reactive force, an overflow pipe and a drain valve can rise upwards, and the drainage can be carried. Buoyancy of a float ball can apply force to the drain valve by a control switch, the sealing performance of the drain valve can be improved, and the zero leakage can be reached; when the buoyancy of the float ball enable the drainage by the control switch, the falling time of the drain valve can be prolonged, and the displacement can be increased.
Description
The utility model relates to the valve switch technology, is a kind of vapour-pressure type toilet cistern draining valve, and it belongs to daily class.
The purpose of this utility model is to develop and a kind ofly promotes draining valve with air pressure, with the buoyancy of the small floating ball power as gauge tap, strengthens its sealing performance, and its displacement is increased.Present most draining valve is strengthened its sealing by the hydraulic pressure in its water tank, but hydraulic pressure is little, the water seal weak effect.The pressurization of the employing counterweight of minority fluid pressure type or spring, but piston cylinder operator complexity, and hydraulic pressure is when being lower than 0.0294MPa, disabler.The utility model adopts the hollow spherical crown sucker (granting patent) of the patent No. 942430646, reaches complete watertight purpose.
Practical the utility model purpose technical scheme is such: the gauge tap on the overflow pipe is one long narrow, and the top is 1/4 circular arc, apart from bottom, top certain distance the concavity circular arc is arranged.Gauge tap control ball float position, when draining valve rose, ball float and lever were in level, and ball float is subjected to the buoyancy support, postpones the fall time of gutter, increases displacement.When draining valve fell, the buoyancy of ball float forced in overflow pipe, and it is tightr that the draining ferrule is got.Pneumatic pipe cleaner is crossed air chamber and is promoted air chamber cover, overflow pipe and draining valve with reaction force.
The utility model concrete structure is provided by following examples and accompanying drawing.
Accompanying drawing is the sectional view of the utility model structure.Wherein: 1-gutter, 2-support, 3-draining valve, 4-ball float, 5-lever, 6-gauge tap, 7-overflow pipe, 8-spilling water pipe box, 9-flexible pipe, 10-nut, 11-air chamber, 12-air chamber cover, 13 guide rods, 14-guide groove.
Concrete structure of the present utility model and working condition now are described in detail in detail in conjunction with the accompanying drawings.
Vapour-pressure type toilet cistern draining valve of the present utility model comprises: gutter (1), support (2), draining valve (3), ball float (4), lever (5), gauge tap (6), overflow pipe (7), spilling water pipe box (8), flexible pipe (9), nut (10), air chamber (11), air chamber cover (12), guide rod (13), guide groove (14).
The cylinder that air chamber (11) is made for plastic cement, an end of cylinder have a plastic cement hollow hemisphere that connects cylinder interior, with air chamber cover (12) and nut (10) air chamber (11) are fixed.Guide rod (13) is fixed on above the support (2).Support (2) is an one with gutter (1).Air chamber cover (12) also is an one with overflow pipe (7).Draining valve (3) is set in the end of overflow pipe (7).Spilling water pipe box (8) is meshed with overflow pipe (7) with thread.Overflow pipe (7) can slide up and down in three guide grooves (14) of support (2).The fulcrum of lever (5) is on support (2), and its end is connecting ball float (4), and the other end is the little cylinder of diameter.Ball float center to the distance of fulcrum is fulcrum 5-6 times to cylinder centre distance.Gauge tap (6) be one narrow rectangular, it is cemented on the overflow pipe (7), the top is 1/4 circular arc, apart from bottom, top certain distance the concavity circular arc is arranged.When draining valve (3) sealing gutter (1), the cylinder of lever (5) is pressed in the top of gauge tap (6) just.When draining valve (3) top rose to support (2) position, the cylinder of lever (5) was pressed in the concavity center of arc place of gauge tap (6) just, makes ball float (4) and lever (5) be in level.The sucker of the hollow spherical crown that draining valve (3) is made by the high-quality plastic cement.
Air enters air chamber (11) from flexible pipe (9), and the hollow hemisphere of air chamber (11) is outwards heaved, and stresses on air chamber cover (12), and air chamber cover (12) drives overflow pipe (7) with reaction force and draining valve (3) rises together along guide groove (14), carries out draining.At this moment the cylinder of lever (5) just in time is pressed in the concavity center of arc place of gauge tap (6), because the buoyancy of ball float (4), overflow pipe (7) and draining valve (3) obtain the support of buoyancy, when the water of water tank will drop to the bottom of ball float (4), buoyancy disappears, overflow pipe (7) just falls along guide groove (14) vertical, postpones fall time, and displacement increases.When draining valve (3) sealing gutter (1), the cylinder of lever (5) just is pressed in the top circular arc of gauge tap (16), and the buoyancy of ball float (4) overflow pipe (7) of exerting pressure makes draining valve (3) and gutter (2) mouthful seal closelyr.This has just stopped drainage fully.With thread lifting spilling water pipe box (8), but the water level of regulating tank.
