Abstract

The utility model relates to a water level automatic control floater valve of water filling tank or pool. The plastic UPVC the same as the water tube of national standard is applied to form a rectangular tee tube structure shell whose mouth is closed. A return spring is installed on the inner wall of the shell, and the return spring is connected with a lever. One end of the lever is connected with a water sealing flap-door, and the other end is connected with a counterweight floater through a steel rope. Therefore the automatic and reliable control of the water level is realized. The design of the water sealing flap-door with reasonable open structure, and a water sealing box with steel rope as well as a water sealing box of lever rotating shaft makes the floater seal water rigorously. The utility model has advantages of simple structure, small volume, light weight, convenient installation and maintenance, reliable water sealing performance, long service life and low cost. Therefore the utility model is an ideal substitute product for prior floater.

Description

Water level is controlled float-controlled valve automatically

The utility model is suitable for the water level that water body charges into water tank or pond and controls automatically.

Everybody controls float-controlled valve by known water level, and style is more, can be divided into two classes on structure and working principle: the one, and Lever type, no shell, part material mostly is cast iron, and volume is big, weight is big, the structure assembling is messy; Big, the water shutoff of installation difficulty is worked poor in the pond.The 2nd, rely on water body self pressure to form the small ball that the recoil effect promotes the automatic water shutoff of piston, this valve principle science, but machining accuracy, material requirements are very high, mostly be cast copper production, its shortcoming is: 1., the pressure using scope greater than 0.1Mpa less than 0.6Mpa, if less than 0.1Kpa then hydraulic pressure is tried hard to recommend not open piston spring, greater than 0.6Kpa, the piston clearance cooperates and has exceeded the pressure using scope.2., the turbidity of water is required very tight because the water shutoff core component is a piston, small solid particle can seized piston in the water.3., complex structure, operational failure rate height, checking maintenance will arrive manufacturer, and land used can't be overhauled.4., the machining accuracy height, cost of production is big.

The objective of the invention is to design a kind of simple in structure, volume is little, and is in light weight, easy for installation, and water shutoff is reliable, honest and clean at the bottom of the cost, checking maintenance convenient, and the water level of long service life is controlled float-controlled valve automatically.

The utility model has been realized above-mentioned purpose from theory structure.

The utility model has the advantages that: 1. flexible operation, production technology is simple.To be that UPVC is plastic injection-moulded make this valve member shell.Inner water shutoff flap valve and ring for the sealing liquid are made by iron casting, are difficult for getting rusty, and lever and rotation system are that stainless steel is made, and have guaranteed this part rotation flexibly.The supporting compactness of this jam pot cover water part, rotating all is to be movably hinged, and meets the sport dynamics principle, thereby has guaranteed that water shutoff is tight, it is flexible to open.This valve parts is simple in structure, and the surface of contact that removes water shutoff iron covering and following ring for the sealing liquid needs certain degree of finish and smooth being outside one's consideration, and other part need not too high machining accuracy as long as guarantee structural strength, and general production technology can be produced.2. low processing cost, parts 95% are for being easy to forming U PVC, and 5% is steel, so reduced manufacture cost, compares with existing same model valve, and weight has only 1/4.3. sturdy and durable, be suitable for pressure 0 to 1Mpa.Valve shell design pressure 1Mpa, internal structure is owing to the pressure balance of water body, and intensity and water pressure are irrelevant, and during valve closing, hydrostatic pressure is big more, and water shutoff flap valve vertical pressure is big more, and water shutoff is tight more.4. checking maintenance is convenient, and this valve whole part is and assembles, and water intake is bigger, and need not open valve body also can be with whole part fast assembling-disassemblings.5. not tight to the turbidity requirement of water, this valve intake-outlet water body smoothness, water shutoff partly is the flap valve opening type, local head loss is less, as long as water body can flow in pipeline, and just energy opening and closing of valve, even small solid particle is arranged in the water, high pressure water can rinse out at once.Valve opening is closed all by Der Grundsatz der Maschinen, and irrelevant in water body pressure size, 0.1Mpa also can proper functioning with downforce.

The utility model is achieved in that

The utility model shell (1) is the UPVC plastics right-angle tee pipe that seals flatly, and shell (1) upper orifice connects the float-controlled valve intake pipe through loose flange (2), and lower nozzle is with straight-through pond of water shutoff flap valve (19) or water tank.Connect restoring spring (6) through ring-like screw (7) on inner, the perpendicular long face sidewall of shell (1), restoring spring (6) the other end connects in lever (8); Lever one end connects in lever rotating hinge (9), and the other end is a sagging wire rope (25), and wire rope (25) passes shell (1) bottom by the sagging counterweight float (26) that connects of wire rope water shutoff box (22), as Fig. 1.

Perpendicular long tube sidewall bottom, water shutoff flap valve (19) upper horizontal at shell (1) three-way pipe structure are crossed lever rotatingshaft (10), and lever rotatingshaft (10) is fixed on the shell (1) through lever rotatingshaft set screw nut (29); Lever rotatingshaft set screw nut (29) is sealed on the shell (1), as Fig. 2 through lever rotatingshaft water shutoff box (27).

At lever (8) one end positions hexagonal lever rotating hinge (9) is installed, lever rotating hinge (9) is through matrix lever resistance arm (11) fixed lever resistance arm loose pin (12), lever resistance wall loose pin (12) camber line is opened garden shape water shutoff flap valve (19), water shutoff flap valve (19) is fixed in shell (1) bottom by flap valve loam cake (16) through convex rotating stand (17), rotating stand axle (18), as Fig. 1, Fig. 2, Fig. 3.

Wire rope water shutoff box (22) is a cylindrical shell, interior dress rubber stopper (23), bottom wire connection convex plug (28).

The present invention can be installed in the pond according to usage requirement, also can be installed in outside the pond.During work, when water body when the pond water intake enters float-controlled valve, because the pond is anhydrous, float (26) is unsettled, and under float deadweight effect, pull lever (8) makes water shutoff flap valve (19) rotate around thick stick rotatingshaft (10) and opens, water body flows out from water outlet (21), along with rising in the pool inner water position, water body levitating float (26), steel wire rope tension disappears, restoring spring (6) is with water shutoff flap valve (19) drawing, under hydrostatic pressure, water shutoff flap valve (19) tightly is pressed on the ring for the sealing liquid under the flap valve (20), and water-filling stops in the pond, when the pool inner water position descends, float (26) is unsettled, working procedure above repeating, and the pool inner water position remains at design water level.
