Abstract
The utility model relates to a pressure difference soft siphon pipe drain valve for a toilet cistern. An existing metal siphon pipe is changed into a soft siphon pipe, and the bow-shaped back part of the siphon pipe is provided with a floating body. A soft balance pipe is arranged adjacent to the bow-shaped back part, and the floating body and the balance pipe are both connected with a deflector rod. The open and close of a manual control valve is realized on the basis of the basic principle of an original siphonage controlled drainage valve, so the utility model is suitable for both elevated cisterns and lower cisterns. The utility model has no alignment problem or blocking phenomenon, and has the advantages convenient installation, high reliability, low cost, easy quality control and no rust. The utility model is a preferred product for replacing the existing ball-plug type or tilting plate type drain valve.
Description
The utility model relates to sanitary equipment water tank draining valve, relates in particular to a kind of sanitary equipment water tank with differential soft syphon draining valve.
Siphon control type draining valve (being commonly called as " fuse certainly falls into water ") is had it long ago, and generally is used for the high level cistern automatic ration and discharges water.Common used syphon is the metal syphon, and constantly to the water tank water filling, siphon formed when water level had its metal syphon back of a bow during use, and valve film upside produces low pressure, under differential pressure action, lifts on the valve film and quick water storage.Siphon termination valve film resets after the water emptying, repeats water storage again, goes round and begins again.Though this kind draining valve reliability height, life-span are long, can only Automatic Cycle control, can not realize manual control, be restricted during use.
The purpose of this utility model is: the defective that overcomes prior art, existing siphon draining valve is improved, but a kind of opened manually is provided and the sanitary equipment water tank of closing with differential syphon draining valve in order to replace relatively poor ball-and-spigot of present reliability and turnover plate type low water stage case draining valve.
The technical solution of the utility model is: existing siphon control draining valve improved, changes the metal syphon into a flexible pipe, make, be fixed with a buoyancy aid that links to each other with driving lever by tightrope in its hunchbacked portion by plastics or rubber, and manually opened to realize; Also can near hunchbacked portion one balance pipe that is fixed with weight on it be set by threeway simultaneously, and weight be linked to each other with driving lever, with the realization manual-lock with tightrope at syphon.
The utility model does not have moving component except that the valve film, not friction, reliability height; Be that very random flexibility connects between soft syphon, soft balance pipe and the driving lever, do not have the problem of centring, do not have the jam phenomenon extremely and take place, install easy to adjust; And the overwhelming majority is an injection-moulded plastic part, and cost is low, and quality is easy to control and Never-rusty.Thereby replacing existing ball-and-spigot or turnover plate type draining valve with it, advantage is fairly obvious, and good economy and society benefit is arranged.The utility model also is applicable to lower water box owing to can not be only applicable to high level cistern by the opening and closing of hand control valve.
Accompanying drawing: be structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is elaborated.
The utility model is made up of valve seat 8, syphon 10, draining valve 6, valve film 15 and loam cake 14, on loam cake 14, be connected to syphon 10 and have balance pipe 13, the other end of syphon 10 is connected on the gutter 6, is fixed with valve film 15 with screw 5 between the flange portion of valve seat 8 and loam cake 14 flange portion.Syphon 10 is made by plastics or rubber, its hunchbacked portion is fixed with the buoyancy aid 9 of bubbling through the water column at ordinary times, be connected to threeway 11 by the disconnection of back of a bow place, be connected to soft balance pipe 12 in the threeway 11, balance pipe 12 openends 4 are fixed with demersal at ordinary times weight 3, and buoyancy aid 9 and weight 3 all are connected in the diverse location of driving lever 1 end with tightrope 2.
Operating principle of the present utility model is: the distance of supposing gutter 6 exits and valve film is h, it is H that water tank is filled to predetermined water level by water intaking valve, film upside lifting surface area is S2, and the delivery port lifting surface area is S1, and then the downside lifting surface area is S2-S1, so the stressed F2 of upside is greater than the stressed F1 of downside, under pressure differential F2-F1 effect, the valve film presses down, and seals main delivery port, water level is higher, and sealing is tighter.
If rotating lever 1 is drawn in buoyancy aid 9 in the water together with syphon 10 hunchbacked portions clockwise, siphon forms, pressure head h sets up, and is that the suffered pressure head of valve film 15 upsides is-h in the A chamber, and the suffered pressure head of valve film 15 downsides still is H, so F1＞F2, valve film 15 lift on rapidly, delivery port is freely opened.Even on the hunchbacked portion returning to the surface, valve can not cut out automatically yet.
With A chamber water-filling, but all less because of their bore, damping action is big, does not influence the foundation of A chamber negative pressure at syphon.If anticlockwise rotating lever 1 is left the water balance pipe 12 openends 4, then air enters syphon, and siphonage is destroyed, valve film 15 upper and lower side pressure head restoring balances, the valve film 15 multiple delivery ports that seal again.So just realize the Artificial Control waterdrainage amount, helped water saving.If soft balance pipe 12 is not left the water or the water intaking valve of threeway 11 and balance pipe 12 is not set, then the draining port of export 4 or the balance pipe 13 that continue up to balance pipe 12 surfaces naturally, till the water tank emptying.
Soft syphon 12 is got limited length, make water inlet is out of control when surpassing predetermined water level can its hunchbacked portion of submergence, form automatic draining, to avoid the accident of overflowing.Can save special bleed off pipe like this, also can be used for high level cistern and make quantitative automatic draining valve.
