Abstract

The invention discloses a direct-discharge ball valve sealing technique for a toilet seat. A circular ball valve is in single-side matched seal with the bottom neck of a sitting pan by a sealing ring, the central points on two sides of the ball valve are oblong blind holes, a central shaft is matched with an oblong embedded part by a top cap and a pressure spring to play a role in relieving the friction force of the ball valve and can be automatically adjusted and sealed, a tap water pipe pressure cylinder is used as ball valve switching power, a telescopic rod is connected with a ball valve rotating rod, and cover seats at two ends of the water pressure cylinder are provided with water inlet pipes which are controlled with two water conveying pipes of a switch and controlled by the switch; and when inlet water pressure at one end of the water pressure cylinder pushes a piston rod to move, a central shaft rod is pulled to rotate so as to open the direct-discharge circular ball valve of the toilet seat, and the sealed circulating operation is automatically closed after the flushing is finished. The efficient water-saving technical key of the toilet seat is to replace an s-shaped bend by a direct-discharge method, only a little water is used for flushing, and the plugging of the toilet seat is avoided.

Description

Toilet direct-discharging ball valve sealing technology

Technical field: the present invention relates to sanitaryware, is toilet direct-discharging ball valve sealing technology.

Background technology: existing toilet leaks for anti-peculiar smell.All adopt the mode of S type bend implementation water seal, can only be confined to the fluidised form blowdown of water, must use the above water source of 3L-6L, with belonging to only together of water from the mobile dirt-carrying of gravity.Can not bring into play this water saving method for discharging pollution of dynamic hydro-peening, add that S type bend is in ceramic process, inwall can't guarantee smooth, by the uncertainty of dirt removal thing, so caused existing toilet to need more than the water consumption 3L-6L, and stop up often, need just to rinse well for several times, make toilet become among the human lives big of main water consumption.In face of the crisis that freshwater resources lack day by day, must reform toilet, wherein blowdown mode is decision water supply volume and the key that causes fault.

Summary of the invention: toilet organ pipe pressure energy direct-discharging ball valve sealing technology

Present technique is by forming with lower member:

Seat basin 1, threeway 2, ball valve 3, joint ring 4, central axis 5, axostylus axostyle 6 (Fig. 1), square blind hole 7, top cap 8, stage clip 9, O type circle 10 (Fig. 2), hydraulic cylinder 11, cylinder seat 12, cylinder seat 13, expansion link 14, water pipe 15, water pipe 16 (Fig. 3), fixedly ceramics 17, rotation ceramics 18, fixing back ceramics 19, water hole 20, water hole 21 (Fig. 4), switch enclosure 22, water outlet through hole 23, the through hole 24 (Fig. 5) of intaking.

Modular construction forms and operation principle:

The present invention adopts ball valve 3 in blowdown threeway 2, contact sealing with 1 time neck of seat basin with sealing ring 4 single faces, be bumped in the ball valve 3 opposite side rectangle blind holes 7 (Fig. 1) by central shaft 5, the position that is bumped into of central shaft 5 and rectangle blind hole 7, by top cap 8, the automatic-sealed of stage clip 9 is regulated, above single face sealing, make the ball valve half-twist unlatching, close spin friction power and reduce to minimum, automatically regulate sealing, regulation loss (Fig. 2). As adopt ball valve dual face seals technology, and will increase by tens times of ball valve spin friction power, can't remedy the loss of seal. Two road O RunddichtringOs 10 are arranged on the central shaft 5, prevent that peculiar smell from releasing from central shaft. 90 ° of switch motions of ball valve 3, there is hydraulic cylinder 11 to link to each other with axostylus axostyle 6 by expansion link 14, two limit cylinder seats 12 on the

hydraulic cylinder

11,13 with switch outlet pipe 15,16 (Fig. 3) are communicated with respectively, by hydraulic cylinder piston transformation power, implementing the switch motion to ball valve 3 with the running water pipe pressure energy, is to be subjected to switch enclosure 22 controls. Switch is made up of three ceramic valve plates, fixedly ceramics 17 and rear ceramics 19, about two limits up and down equidistant water hole is respectively arranged, respectively there is a water hole on middle rotation ceramics 18 2 limits, wherein going out two water holes of the water surface has return flume (Fig. 4). Have into water through hole 21 under switch enclosure 22 shells, on water outlet through hole 20 is arranged, be threaded to water hole 20 water inlets such as ceramics 18 in the rotation, then hydraulic cylinder seat 12 water inlets, the piston rod retrude, 3 of ball valves are closed, and the water in the former hydraulic cylinder 11 has cylinder seat 13 to enter water outlet through hole 23 by the return flume of ceramics 18 in 21 warps, and decompression is zero; Otherwise, switch opens, water hole 21 water inlets, pushing piston bar 14 stretches out, and namely opens ball valve 3, and the water of hydraulic cylinder 11 pressure-reliefs to zero equally by cylinder seat 12, has middle ceramics return flume to discharge through water outlet through hole 23. For this reason, do not have pressure in switch and the hydraulic cylinder action, make action accurately errorless, rapid sensitive.

The present invention by the hydraulic cylinder transformation power, implements the opening and closing sealing to ball valve with the running water pipe pressure energy; The ball valve single face is regulated Sealing Technology automatically; The no pressure of switch is worked in coordination with switching motion, complex art has substituted for a long time, and toilet leans on the water seal of S type bend, waste the water source, send out repeatly fault, infect the outmoded conventional art that bacterium is fled, be high-efficiency water-saving, stop fault, the science toilet of new generation in isolation bacterium source provides robust techniques.

Claims

1. the in line ball valve sealing feature of toilet of the present invention is: in the blow-off pipe, adopt neck sealing under ball valve, joint ring and the seat basin in toilet.

2. the dynamic characteristic that opens and closes automatically of toilet seal ball-valve of the present invention is: press by the flexible power of hydraulic cylinder conversion with running water pipe and implement.
