Abstract

The utility model relates to a time-delay self-closing flushing valve with two flushing methods, which belongs to the improvement of a flushing valve. The water discharge quantity of excrement and urine of the present flushing valve has no difference, so water is wasted when the urine is flushed. The time-delay self-closing flushing valve has two sets of starting mechanism, which realizes variable water discharge and is used for flushing excrement and urine respectively. The utility model has the advantages of convenient use and water saving.

Description

Self-closing flushing valve with two time-delay flushings

The utility model belongs to the improvement to self-closing flushing valve.

Existing self-closing flushing valve just can not divide class towards large and small, and dashing the urine water requirement should be less, but still discharges the water yield of as much, therefore causes the waste of the water yield.

The purpose of this utility model provides a kind of towards the large and small water-saving flushing valve that just divides class.This flushing valve is made up of valve body, valve gap, piston, adjustment screw, spool, spring, spring capping, guide grab, two cover actuating mechanisms and antifouling acceleration etc.Actuating mechanism is by push rod, gland, rubber spring, button, button gland, the actuating mechanism that dashes urine is positioned at the actuating mechanism below that dashes stool, make valve body rise to that the certain altitude back valve core breaks away from push rod and the discharge time of controlling flushing valve, reach the purpose of water saving.Antifouling accelerator partly is by accelerator, joint, binding nut, and two apertures are arranged on the joint, and its effect is when pipeline generation negative pressure, can produce the air insulating course, prevent the odor pollution water source of urinal.

Below in conjunction with accompanying drawing the utility model is done detailed explanation.

Fig. 1, the front view of flushing valve, and represent its internal construction with analysing and observe.

Fig. 2 is the A-A sectional drawing.

Blacking partly is rubber seal among the figure.

Embodiment one

Valve body 4 adopts with valve gap 3 and is threaded, spring 31 is pressed on the spool 32 through spring capping 30, spring capping 30 adopts thread connection with piston 5, adopt sealing ring 7 sealings between piston 5 and the valve body 4, guide grab 8 adopts thread connection with piston space, and stop screw 1 adopts thread connection with valve gap 3, comes the lifting height of limited piston by the position that stop screw is set up, the control discharge time has individual damping hole 6 on the piston.Inlet attack 28 is connected with running water pipe, it is fastened on the valve body by binding nut 29, joint 17 adopts thread connection with valve body, and will speed up device 16 and be fastened on the valve body, binding nut 19 is used for connecting cleaning hose, and the hole the 18, the 20th on the joint is in order to prevent the odor pollution tap water water source in the closet.Structure towards large and small actuating mechanism just is identical, and the axis that dashes the push rod 27 of urine dashes stool push rod 15 axial location and moves down a position.The areole of push rod 15,27 and valve body is slidingly matched, one end of rubber spring 12,23 is fastened on the push rod through nut 14,26, the other end is fastened on the valve body through gland 11,23 usefulness clamp nuts 12,22, connect button 13,24 endoporus at gland and be slidingly matched, the extreme position of its outside motion is limited by clamp nut 10,22.

The course of work of this valve

When dashing stool, press the button 13 that dashes stool, push rod 15 promotes spool 32, water in the control chamber 2 flows out, and piston 5 is under action of pressure, and is up rapidly, run into stop screw 1 up to piston, simultaneously, flushing valve begins to discharge water, hand breaks away from the button valve core reset, at this moment, water is through filter screen 33, damping hole 6 flow in the control chambers increased pressure and under action of pressure, promote descent of piston, close automatically at last and stop to discharge water.When dashing urine, press the button 24 that dashes urine, piston is risen, and this moment, piston rises to spool 32 disengaging push rods 27 is just resetted, at this moment, the piston lifting height is determined by the relative distance of the top edge of the lower end of spool and push rod 27, the lifting height of piston is little, and the discharge time of flushing valve is also few, limits the waterdrainage amount that dashes urine with this.

Embodiment two

In this embodiment, be to adopt restriction to limit the discharge time of flushing valve towards the method for the stroke of urine push rod 27.The course of work that it dashes urine is like this: press the button 24, push rod promotes the spool rotation, because the stroke of push rod 27 is subjected to the restriction of step part 21, thus the anglec of rotation of control spool.Piston rises, and the opening of spool bore reduces, the flow that flows out from spool bore when the water in the control chamber with mend from damping hole into flow when equating, piston will no longer rise,, come the lifting height of limited piston with this, control the discharge time of flushing valve.In this scheme, dash the relative position and the no requirement (NR) of axis with the axis that dashes the stool push rod of the push rod of urinating.

Characteristics such as in summary, this flushing valve has easy to use, and water-saving result is remarkable.

Claims

1, a kind of two jig frequency delayed self-close flushing valves, by inlet attack 28, clamp nut 29, valve body 4, valve gap 3, piston 5, sealing ring 7, spool 32, spring 31, guide grab 8, stop screw 1, accelerator 16, compositions such as joint 17 and binding nut 19, valve body 4 adopts with valve gap 3 and is threaded, spring 31 is pressed on the spool 32 through spring capping 30, spring capping 30 adopts thread connection with piston 5, guide grab 8 adopts thread connection with piston space, individual damping hole 6 is arranged on the piston, inlet attack 28 is fastened on the valve body through binding nut 29, joint 17 adopts thread connection with valve body, and will speed up device 16 and be fastened on the valve body, two holes 18 are arranged on the joint, 20, it is characterized in that this flushing valve has two cover actuating mechanisms, be used for start dashing big respectively; urine; the push rod 15 in the actuating mechanism; 27 do slidingly to cooperate entirely with the areole of valve body; rubber spring 12; end of 23 is through nut 14; 26 are fastened on the push rod; the other end is through gland 11; 23 usefulness clamp nuts 10; 22 and be fastened on the valve body; button 13; 24 endoporus at gland are slidingly matched; the extreme position of its outside motion is by clamp nut 10; 22 limit, towards the axis of the push rod 27 of urinating than moving down a position towards push rod 15 axial location of defecating.
