Abstract
The utility model relates to a self -imposed flashing valve of push type. The resistance is great when mainly having solved current push type flashing valve and pressing, the bath time short and bath effect relatively poor problem. Its characterized in that: the lower extreme of valve rod (3) is located closed chamber (11) of filling hydraulic oil of valve body (1) below, and the lower extreme of valve rod (3) is fixed with piston (12), piston (12) cross -section be " worker " font, be equipped with oily through -hole (13) and damping through -hole (14) on piston (12), piston (12) overcoat has floating seal ring (15), floating seal ring (15) can make oily through -hole (13) to be in the shutoff and to open two types. This self -imposed flashing valve of push type adopts reset spring, piston and floating seal ring cooperation, and the resistance is less when pressing the knob down, can open the case according to the knob down fast and make the case slowly restore to the throne and close, has bath time invariant, can guarantee the bath time and wash by water effectual characteristics.
Description
Technical field
The utility model relates to a kind of for the urinal flushing valve in public lavatory, is specifically related to a kind of press-button self-closing flushing valve.
Background technology
At present, the toilet flushing in public lavatory generally all adopts pressing flushing valve, presses the button rear auto-flushing and time-delay closing, to reach the object of water saving.Existing pressing flushing valve forms primarily of valve body, valve rod and button, back-moving spring is provided with between button and valve body, valve rod connects leather cup, the direction of leather cup opening is utilized to carry out delays time to control, when namely pressing the button, leather cup opening is retracted, after lifting button, leather cup opening opens, and the increase of valve rod backhaul resistance slowly resets.There is following technological deficiency in this pressing flushing valve: 1. when pressing the button, resistance is difficult to more greatly make valve reach maximum opening, and flushing period is short, and flushing effect is poor in use; 2. during Long-Time Service because leather cup wearing and tearing delay time is shorter, valve rod resets very soon, and flushing period is unstable, and flushing period equally also can be caused short, and flushing effect is poor.
Utility model content
In order to overcome the deficiency that when existing pressing flushing valve is pressed, resistance is comparatively large, flushing period is short and flushing effect is poor, the utility model provides a kind of press-button self-closing flushing valve, this press-button self-closing flushing valve adopts back-moving spring, piston and floating seal ring to coordinate, when pressing the button, resistance is less, can press the button fast and open spool and spool is slowly resetted closedown, have flushing period constant, flushing period and the good feature of flushing effect can be ensured.
The technical solution of the utility model is: a kind of press-button self-closing flushing valve comprises valve body, spool and valve rod, valve body is provided with water inlet and delivery port, spool is fixed on valve rod, above valve body, valve gap is installed, the lower end of valve gap is provided with valve seat, the sidewall of valve gap is provided with the exhalant canal corresponding with delivery port, valve rod upper end is run through valve gap and is connected button, back-moving spring is provided with between button and valve gap, the enclosed cavity filling hydraulic oil that the lower end of valve rod is positioned at below valve body is indoor, the lower end of valve rod is fixed with piston, described piston cross-section is " work " font, piston was provided with oil hole and damping through hole, piston jacket has floating seal ring, floating seal ring can make oil hole be in shutoff and open two states.
Be provided with the first sealing ring between described valve body and valve gap, between valve rod and valve gap and between valve rod and valve body, be provided with the second sealing ring.
Described valve body lower end is connected with end cap.
The utility model has following beneficial effect: owing to taking such scheme, when pressing the button, valve rod band movable valve plug moves down, now floating seal ring is floating upward, cross oil hole to open, the hydraulic oil of piston lower chamber passed through oil hole and damping through hole enters into piston upper chambers fast, presses the button and be easy to reach maximum opening; Release button, floating seal ring blocked oil hole, the hydraulic oil of piston upper chambers can only be back to piston lower chamber by damping through hole, and valve rod slowly resets under the effect of back-moving spring and damping through hole, can set the time-delay flushing time by the pore size of setting damping through hole.The utility model pressing button is light, and flushing period is constant, can ensure flushing period, and flushing effect is good, failure rate is low, long service life.
