Abstract

There is described a valve arrangement which in one form is an inlet valve (60) or in another form is a dual flush valve (2). The valves may be used in a variety of situations but find particular application in a cistern for providing water to flush a toilet bowl or similar. The valve arrangement (2) comprises a flushing tube (100) or a pair of flushing tubes (14, 18) which can move axially. One end of the tubes (100, 18) is sealed to an outlet (9). The tubes are provided with rings or collars (16, 22) which co-operatively engage with locking edges (48, 50) of floats (40, 44) to control movement of the tubes (100, 14, 18). The floats (40, 44) are mounted off-centre or in a position spaced apart from their respective centres of gravity so that they are free to move under the effects of gravity and the effects of lift provided by buoyancy of the floats. In operation the sequential effects of gravity and buoyancy cause the floats to hold the tubes in position and then release the tubes thereby allowing selective flushing positions.

DETAILED DESCRIPTION OF THE INVENTION                                  Valve device   The present invention Generally a valve, In one form, the valve is particularly immersed in the fluid whose flow is controlled To the valve Another aspect relates to a valve, in particular for controlling the flow of a flowing fluid. . More specifically, The present invention liquid, In particular, it relates to a valve for controlling the flow of water. For more information, The present invention It is a suitable valve if used in a water tank for flush toilets, etc. What An inlet valve for filling the water tank, To control the release of water from the aquarium More particularly, it relates to a flushing valve such as a double flushing valve provided in a water tank. The present invention Office Area, Hotel, In water tanks installed in buildings such as ordinary homes Double flushing valve and / or inlet valve for aquarium with two modes of operation Especially used.   The present invention With particular reference to tanks having dual flushing valves and / or inlet valves. Is explained, The present invention Not limited to such devices and applications, Of the present invention The range is Rather, a wide range of devices and applications other than those described and described here It should be noted that   One problem with existing aquarium inlet valves is that Such a valve, Two extreme positions It is to work slowly. Therefore, There are various flows of water entering the aquarium, This This is the effect that is called "hissing" I.e. the toilet is washed Undesirable noise, such as the sound of water entering the aquarium after being dropped, has consequences. This noise Inlet valve slowly approaches fully closed position by restricting water flow slowly Due to that. In extreme cases, This unwanted noise Even after flushing the toilet bowl May last for a long time, This annoys people, Irritate. Especially, Midnight stretch When the aquarium is released in the current situation, Wake up sleeping in adjacent bedroom or apartment Will be.   Other problems with current valves for aquariums are: The complexity and bulk of these valves, This is the valve in the aquarium, Especially, large space is occupied by the valve operating mechanism. ing. This is This time requires a tank of large dimensions. Large tanks Reduce the number of places in the building where water tanks can be installed, Design a water tank and a room with a water tank You Reduce the flexibility of the designer.   Another problem with single flushing valves is that These valves are Not used when washing with water Because we have no provision to reduce the amount of water needed, It means wasting water.   Existing aquarium valve, Other problems, especially with dual flushing valves, Work together Have a number of separate components, Operation and manufacturing are complex. Such a valve device is Not only is production cost high, Especially, For example, pivot series Binding, Where adjacent components such as pins are connected to each other, Seal element In the place provided, The components wear over time. Operation of the valve or The wear of the actuation mechanism and / or the wear of the sealing element Water leakage between components Or excessive clearance between components This time, Aquarium efficiency and effectiveness Diminish the nature, Insufficient inlet and outlet seals resulting in excessively frequent repair needs Such leakage or other problems may occur. In many cases, As a result of excessive wear, The valve is More or less continuous leaks, Or there is a leak from the tank, especially to the toilet bowl. Rashi, that time, While the valve oscillates between the half-open and closed positions, Water is continuously added to the aquarium When filled, it entails undesired noise, including annoying hashing. in addition, Constant leakage from the aquarium, Produces unsightly spots on the toilet.   Therefore, Flushing valve, Especially in water tanks such as double flushing valves for water tanks A valve device suitable for the use of Works efficiently, Consists of a small number of components, space Without taking Quiet or almost silent when activated, And it works effectively, Maintenance Little or no need, There is a need to provide a valve device that can be assembled inexpensively.

The present invention In the semi-flush operation of the flushing valve 2 of The aquarium is As shown in FIGS. Up to a level near the top of the upper tube 14. Water is Open top At a level below the upper edge of the inlet pipe 14 The upper support bracket 10 of the main frame 4 Note the abbreviation for the bell. When the aquarium is full of water, Top and bottom Funnel 40, 44 is Take the angularly inclined position shown in FIGS. Each float 40, 44 lock edges 48, 50 is In particular, as shown in FIG. Two inlet pipes 14, 18 are in contact with the side walls, respectively. In this state, The double flushing valve 2 of FIG. The fully closed position Upper pipe 14 against lower pipe 18 which is sealed against outlet 9 Is sealed, Water is stored in the aquarium, Any water released from the aquarium to the toilet Is also prevented. This is, Normal position of the aquarium ready for operation . Water is It is placed in a water tank through a separate inlet valve, described in detail below.   If you need a half flush of the aquarium, The semi-flash button on the aquarium is pressed, This But Push the upper tube 14 up to release the seal fit with the lower tube 18. Activate the extension rod 37, Lower pipe 18 seal fits with seal arrangement 20 Because it stays in the predetermined position The lower end of the upper fitting 14 from the upper end of the lower pipe 18 Let it separate. By this operation, The upper tube 14 Upper float 40 clockwise Turning slightly, Then by returning to the original position, Upper ring 16 is upper flow Can be lifted just past the locking rim 48 of the door 40. as a result, B The hook edge 48 is Abuts against the lower part of the upper ring 16, As shown in FIG. Upper tube 1 4 is locked away from the lower tube 18. In this position, Water is Arrows in Figure 2 It flows freely through the gap between the two tubes as shown at A. The lower pipe 18 This operation Not disturbed by It should be noted that the outlet 9 of the aquarium remains sealed. You.   When the water level is below the upper float 40, That is, the level corresponding to the top of the lower pipe 18 When it drops to The lift given to the upper float 40 by buoyancy is No longer work Stop using it. By the eccentrically pivoted upper float 40, Upper float 4 0 is Turning naturally counterclockwise under the influence of gravity, The lock edge 48 moves and the upper Unlock the ring 16 Take the position shown in FIG. The upper float 40 is Shoulder 49 abuts on the frame member 8, It was noted that excessive turning was prevented No. When the upper ring 16 is released, The upper tube 14 Falling by gravity, again The lower pipe 18 is fitted with a seal, A seal is formed with the V-shaped seal 19. Then Appropriate Water is put into the aquarium by an inlet valve (described in more detail below), as a result, In the aquarium The water level goes up to the original level. The rise in water level raises the upper float 40 , The upper float 40 is This turns clockwise as shown by arrow B in FIG. do it, Take an angled position for the next half or full flash . When the tank is empty, The upper float 40 is vertical, When the tank is full, Up It should be noted that the partial float 40 is inclined with respect to the vertical direction.   In operation of the flushing valve of the present invention in all flush mode, The aquarium is full When The water level is as described above. When all the flush buttons of the aquarium are pressed, Push The rod 33 moves, Connected to lower tube 18 by spider 30 and hole 29 The operating lever 32 is moved to lift the center rod 26. Thus, Lower pipe 1 8 is lifted from the V-shaped seal 21, Seal arrangement 20 The lower pipe 18 rises so as to be disengaged from the seal fitting with There is a gap between them , Through this gap, water flows to the outlet 19 as shown by arrow C in FIG. Lower part Tube 18 only enough to allow ring 22 to pass through locking edge 50 of lower float 44. Is lifted, The lock edge 50 is Abuts on the lower part of the lower ring 22 and Holding the tube 18 in the fully open position, The water level in the tank is lower edge of the lower float 44, I mean Until it drops below the level of exit 9 Maintain the valve in the fully open position. Lower pipe 1 When 8 is lifted like this, The upper tube 14 is also lifted at the same time, Upper tube 1 The seal between 4 and the lower tube 18 is maintained throughout the operation in all flash mode, water It should be noted that the only outlet of is from the bottom of the aquarium. This operation Note that the upper float 40 also pivots. But, All flash In operation mode, The position of the lower ring 22 from the lower float 44, Top flow Because the position of the upper ring 16 from the Upper float 40 is upper phosphorus Because it does not touch There is no effect on the operation of the valve device. further, Both rings 16, The position of 22 is Both pipes 14, 18 is full flash position or half flash position Note that it is something that is held in either. Both floats 40, 4 The lock edge of 4 It is not possible to lock both tubes at the same time.   The lower float 44 Since it is attached like the upper float 40, under The part float 44 is Turning counterclockwise according to gravity, Release lower ring 22 And The lower tube 18 is dropped by gravity to reseal the outlet 9. Then Inlet valve Is It works to put water in the aquarium, The water level is the lower float 44, Then the top flow Ascend above the port 40, as a result, Each float is Now turn clockwise , Lock edge 50 on lower tube 18, The lock rims 48 are respectively brought into contact with the upper tube 14, And Both locking edges are each ring 16, Take the original position above 22.   Another embodiment of the valve device of the present invention, which is an inlet valve 60 (not shown) provided in a water tank Will be described. On the bottom or bottom surface 62 of the tank, Insert the vertical pipe 64, This The pipe is provided with a hole to be sealed by a usual seal stopper. Vertical The pipe 64 is It is connected to a normal pressurized water supply and supplies water into the water tank. To the aquarium Water supply is It is controlled by operating the inlet valve 60 (see FIG. 5).   The inlet valve 60 It is provided just above the water inflow orifice 66 at the top of the vertical pipe 64. , The delivery pipe 68 Spout (not shown) to dissipate inflow water energy And similar nozzles, Operate the valve silently. The inlet valve 60 Vertical section is straight In the triangle, FIG. 6, where the horizontal cross section is U-shaped, With the float 70 shown in FIG. . The float 70 is The vertical pipe 64 is arranged so as to be located within the notch of “U”. , One of the substantially vertical sides of the triangular float is pivoted to the vertical pipe, Other side Is substantially horizontal, These planes are arranged substantially perpendicular to each other, Third slope Is inclined at an angle to the other two planes. But, Precision of above float Note that the exact shape can be changed. Normal Position, That is, the tank is operated with water In the ready position, The float is Inclined at an angle to the vertical pipe, FIG. Are turned counterclockwise from the position shown in FIG. In the float 70, use A yoke 72 is provided at a position along the upper surface when the horizontal plane faces the tip of the inclined surface. Have been. In this yoke, Operating lever 74, Lever 76, Push rod or similar Power, Alternatively, one end of the motion transmitting device or the link mechanism is connected, these At the other end, A cam 78 is connected or provided. This link mechanism or cam , Plunger 80 provided in a suitable housing 82 forming a plunger valve The top of The cam 78 presses. A pair of levers 74, 76 and mosquito Instead of the program 78 Single lever with roller rings at both ends It should be noted that in this case, One of the above roller wheels is a plunger of a plunger valve Acts directly on the key 80.   Between the plunger 80 and the housing 82, Two "O" rings 84, 86 is Provided, Water is prevented from leaking from the housing. Use of plunger 80 At the bottom of time, A pad 88 for selectively opening and closing the water inflow orifice 66 is provided. And Thus, the water from the vertical pipe 64 through the water inflow orifice 66 to the discharge pipe 68 Flow is regulated. The housing 82 Between the top of plunger 80 and cam 78 With adjustable screw to adjust stroke of plunger 80 to create gap With a cap 90 of When the float 70 is in the vertical position, Water flows into the aquarium While When the valve is in the closed position, Seal between pad 88 and orifice 66 Make contact. One variation of the plunger valve is If the valve opens unexpectedly due to excessive water pressure, The provision of a mechanical lock on the plunger valve to prevent water leakage.   In operation of the inlet valve 60 of this form, If the tank is empty, The float 70 is Figure In a vertical position or a substantially vertical position as shown in 5, Cam 78 is a plan Away from Ja80, Release the pad 88 from the orifice 66, Vertical pipe 64 Through the orifice 66 and out through the outlet pipe 68 into the water tank. In the aquarium When the water level increases to near the float 70, The lift applied to the float 70 Overcoming the effects of gravity, The float 70 is Turning counterclockwise as indicated by arrow E in FIG. Turn. As the water level further increases, The center of lift or pressure is shifted from left to right in FIG. Move When the water level reaches just below the pivot point, The float rotates counterclockwise with increasing force Can be turned. The movement of the float 70 is Lever 74, Yoke 72 with 76 Raise, as a result, The lever 76 pivots about the pivot point 77, Cam 78 It comes into contact with the ranger 80. When the cam 78 further turns, Plunger 80 is further pushed into housing 82, Pad 88 is at the end of orifice 66 Part is forcibly contacted, as a result, Water flow to the aquarium is stopped. Float 7 Since the 0 turn is almost instantaneous, The closure of the orifice 66 is immediate, As a result, "Singing" noise It is reduced as compared with the case where the valve is gradually closed in the conventional water tank.   In one embodiment, To reduce unwanted friction Roller wheel used It is.   In FIG. Modifications of the dual flushing valve of FIGS. 1-4 are shown, This change The example is Except that the upper tube 14 and the lower tube 18 are replaced by a single tube 100 It is the same as the valve of FIGS. Therefore, The members corresponding to FIGS. 1 to 4 in FIG. The same reference numbers will be used. in addition, Tube 100 Bracket from bracket 6 A single tube that extends to the socket 10 and can move axially between the brackets during use. So There is no seal arrangement 17 or seal 19. Tube 100 Tube 14 And moves like tube 18, but The lifting amount is small, If you take the half flash position 15mm from the seal 20 Example from seal 20 when taking all flash positions For example, 30 mm.   In operation of this variant of the valve device, The aquarium is filled with water as shown by the water level in FIG. It is full. If you need a half flash, Tube 100 Push rod 37 and lever 3 By the operation of 6, So that the upper ring 16 is locked by the locking rim 48 Can be lifted. In this position, The lower end of the tube 100 is About 15mm away from exit 9 , Water is Outflow from the outlet with a small flow rate until the water level reaches just below the upper float 40 And as a result, The upper float 40 is The engagement of the lock rim 48 with the upper ring 16 Turn counterclockwise to release, The tube 100 is dropped by gravity and the seal 20 To do Thus, The valve is Take the fully closed position after a half flush of water. Lower part The distance at which the ring 22 is separated from the locking edge 50 is The upper ring 16 is separated from the locking edge 48 Because it is longer than the separation distance, The locking rim 50 does not lock the lower ring 22, beneath The ring 22 is located rather below the locking rim 50, Therefore, The lower float 44 , Note that it does not work in semi-flash mode. Half flash After the code The inlet valve 60 It works to refill the aquarium, The upper float 40 , The "ready" position shown in FIG. 8 is taken.   If you need a full flush of the aquarium, The push rod 33 and the lever 32 Tube 100 Operated to lift higher, as a result, Locking edge 50 is lower ring 22 Mated with Lock tube 100 approximately 30 mm above outlet 9. Compatible with all flashes In this position Water flows out through outlet 9 at a high flow rate. In all flash positions, Since the upper ring 16 is located above the locking rim 48, The upper float 40 is all It should be noted that it does not work in the flash position. The water level in the tank is When it drops to just below the funnel 40, The upper float 40 is Counter clock under the influence of gravity Turns in the direction Since the upper ring 16 is located above the locking edge 48, The movement of the upper float 40 has no effect, Tube 100 Lock edge 50 The full flash open position is maintained by abutting the ring 22. Water level When it continues lowering and reaches just below the lower float 44, The lower float 44 is Anti-time Turn in the measuring direction, Release the lower ring 22, Pipe 100 falls onto seal 20 by gravity Let me Let them seal again. Thus, The inlet valve 60 To fill the aquarium Works, Both floats 44, 40 is As the water level rises over each float, now The degree pivots clockwise to the "ready" position under the effect of buoyancy.   The advantages of the inlet valve of the present invention are: Whether in the fully open position or the fully closed position, this Without slow and slow motion between the two extreme positions, Rather instantly between the two extreme positions It is an unrivaled structure that performs a unique operation. This inlet valve Intermediate stops, There is no delay. This advantage is By designing the hydraulic float as Achieved. That is, This float is Fully open position, In other words, the float is shown in Figure 5. The position extending vertically downward like Maintain until the water level in the tank rises to the specified level Continue to Then the valve It can move freely and easily to the fully closed position without noise, To the aquarium It stops the water flow. in addition, Valve moves quickly between fully open and fully closed positions Also, No water hammer occurs.   The lever opens the orifice 66 with considerable force due to the combined mechanical advantage So the float is designed.   When the valve is in the open position, Water is Through the delivery pipe, Water tank at a given angle and constant flow rate Squirted on the wall. The nozzle that spouts water The energy of the incoming water is the side wall of the tank It is designed to be absorbed by and eliminate noise.   Since the flow rate of water entering the tank is constant throughout the filling period, Adopts a slowly closing valve Further, it is possible to reduce the irritating hissing noise associated with the conventional water tank.   Another advantage of the present invention is that The horizontal section of the float's “horseshoe” is a vertical pipe wrap-around. With a round (surrounding) effect, Reduces valve components and space required for operation It is to be.   The inlet valve and double flushing valve of the present invention are: Same so that both valves work together Note that it may be located in the aquarium.   Double flushing valve of the present invention, In particular, a further advantage of the valve of FIG.
