Abstract
The invention belongs to a kind of improvement of water valve, it is characterized in that delay adjustment device being housed on primary seal bowl top, in the core bar central axial direction through hole is arranged, core bar one end is equipped with filter screen, end is equipped with wash water tap and water nozzle adjustment button in addition, make this water valve not only have bath, function such as wash one's hands and hand lever is self-cleaning, and also it is adjustable to delay time.This water valve is simple in structure, easy to maintenance, cost is low, is applicable on family and the public lavatory pipeline to use.
Description
The invention belongs to a kind of improvement of water valve, be specially adapted on family and the public lavatory pipeline.
The water valve kind that is used for the use of family and public lavatory at present is more, but function is comparatively single, and for example the CN87203489U patent application document is announced a kind of flushing valve, and this valve can only play the effect of bath, can not wash one's hands, and it is adjustable to delay time simultaneously; Other has a kind of water valve, though the adjustable self-closing function of time-delay is arranged, structure is complicated, for example " the adjustable self-closing valve of delaying time " of " the delay-adjustable valve " of CN2047684U announcement and CN2051699U announcement.The present invention designs a kind of dual-purpose valve for flushing and washing with time-delay tunable arrangement just for the deficiency that overcomes above-mentioned prior art, the time-delay tunable arrangement has adopted two kinds of forms of the gentle damp type of frictional drag type, make this valve not only have washing capacity, can also be when main valve be worked, the flushing hand lever, and it is adjustable to delay time, and is comparatively ideal multi-functional water valve.
Delay-adjustable dual-purpose valve for flushing and washing of the present invention, comprise that valve body, primary seal bowl, core bar and hand lever form, it is characterized in that delay adjustment device being housed on primary seal bowl top, in core bar central axial direction one through hole is arranged, core bar one end boss is equipped with filter screen by retainer ring, core bar end in addition is equipped with water nozzle and water nozzle adjustment button, and water nozzle is adjusted button bottom aligning core bar central hole tap sealing plug, and hand lever one end yoke type structure directing groove cooperates with the protruding navel of core bar.
On primary seal bowl top delay adjustment device being housed is to be fastened on the valve body by pressure ring, is the conical hollow structure by the elastically deformable middle part and adjusts the frictional drag type delay adjustment device that button is formed by the core bar inwall by the gland of ring-shaped groove and the time-delay on gland top.
On primary seal bowl top delay adjustment device being housed is to be fastened on the valve body with hold-down nut, the outer wall that communicates by the air chamber and the air on primary seal bowl top circumferentially or the time-delay that is used to adjust the air inflow size of end face adjust the gas damp type delay adjustment device that the sealing ring on button and gland and gland top is formed.
Compared with the prior art delay-adjustable dual-purpose valve for flushing and washing of the present invention has advantages such as simple in structure, easy to maintenance, that cost is low, function is many, resistance to water-flow is little.When valve damaged, as long as pin is taken off, hand lever forked type structure just can be pulled down, and whole spool takes off and keeps in repair, and does not need to pull down whole valve.
Below in conjunction with accompanying drawing the technology of the present invention is described in detail:
Description of drawings
Fig. 1 is the frictional drag type delay-adjustable dual-purpose valve for flushing and washing structural representation.
Fig. 2 is a gas damp type delay-adjustable dual-purpose valve for flushing and washing structural representation.
Fig. 3 is the A-A sectional drawing of Fig. 1, Fig. 2.
Fig. 4 is the B-B sectional drawing of Fig. 1, Fig. 2.
Delay-adjustable dual-purpose valve for flushing and washing of the present invention, comprise that valve body (1), primary seal bowl (2), core bar (3) and hand lever (7) form, on primary seal bowl top delay adjustment device is housed, being the conical hollow inner structural wall by the elastically deformable middle part has the time-delay on gland of ring-shaped groove (4) and gland top to adjust the frictional drag type delay adjustment device that button (5) is formed, and is fastened on the valve body by pressure ring (6).Gland is with easily producing elastically-deformable material, for example plastics.Ring-shaped groove in the gland can produce frictional force when core bar moves, the length of the adjustable size joint delay time of this frictional force.
Another kind of gas damp type delay adjustment device is housed on primary seal bowl top, the outer wall that communicates by the air chamber (18) and the air chamber on primary seal top circumferentially or the time-delay that is used to adjust the air inflow size of end face (C to shown in) adjust the gas damp type delay adjustment device that the sealing ring (14) on button (17) and gland (16) and gland top is formed, be fastened on the valve body with hold-down nut (15).
In core bar (3) central axial direction one through hole is arranged, core bar one end boss is equipped with filter screen (12) by retainer ring (13), filter screen can prevent that foreign material from entering the core bar center, general water quality is purer, can not adorn filter screen, core bar end in addition is equipped with water nozzle (9) and water nozzle adjustment button (11), water nozzle is adjusted button bottom aligning core bar central hole tap sealing plug (10) is housed, hand lever (7) one end yoke type structure directing grooves cooperate with the protruding navel of core bar, and the hand lever strong point is fixed on the valve body by pin (8).
When pressing hand lever (7), dual-purpose valve for flushing and washing is opening, and water flows into delivery port from water inlet, reaches the purpose of bath, this moment is because delivery port has certain resistance to current, part water is arranged by filter screen (12) and core bar (3) axis centre orifice flow faucet, can wash one's hands, when hand lever is returned to certain position, current in the water nozzle promptly wash hand lever, reach the self-cleaning purpose of hand lever, make this valve have bath, function such as wash one's hands and hand lever is self-cleaning.When the rotation water nozzle is adjusted button (11), can adjust the size of the water yield of washing one's hands.
Delay adjustment device on primary seal bowl top, a kind of delay adjustment device of frictional drag type makes the groove of gland annular produce frictional force by the core bar motion, adjusts button (5) with time-delay and regulates, and plays the timing closing effect.The delay adjustment device of another kind of gas damp type when adjusting button (17) by adjusting time-delay, changes its air inflow, thereby adjusts the turnaround time of air chamber (18), promptly reaches the purpose that time-delay is adjusted.
When hand lever does not have external force, because the effect of all power such as hydraulic pressure, atmospheric pressure and main close bowl restoring force, core bar is moved to closing direction, end up to the main valve current, wash water tap (9) has also ended current simultaneously, begin air inlet thereupon, make the current in the outlet pipe enter the lavatory urinal, prevent the sewage pollution water source in the urinal.When not needing to wash one's hands or washing hand lever, only need that water nozzle is adjusted button and screw and get final product.Delay-adjustable dual-purpose valve for flushing and washing of the present invention can be adjusted function of use as required.
Delay-adjustable dual-purpose valve for flushing and washing of the present invention does not have specific (special) requirements to water quality, the applied hydraulic pressure scope is 0-60Mpa, can make straight, the series specification of the formula of yet can squaring up.Profile changes, just can be made into adjustable, flow the is adjustable self-cleaning hand washing tap of frictional drag type or gas damp type time-delay, thereby has enlarged the scope of application, and this valve can replace the high-level or low-level water case.
