Abstract

The utility model discloses an automatic water feeding device used with water containers. The utility model comprises a water tank, a valve body, a valve rod, a valve core, a float, and water inlet and outlet tubes. The float goes upward and downward as the water level in the water tank changes, and drives the valve rod to move upward or downward. The valve rod therefore touches or leaves the corresponding positions in the cavity of the valve body to serve the purpose of automatic opening and closing for water feeding. The utility model has the advantages that the valve core, a conical screw and an outlet of the valve rod can automatically adjust the water supply; the opening and the closing can be realized stably; and all the water feeding needs of large, medium and small sized water containers can be satisfied. The utility model has other advantages of simple structure and easy assembly, operation and maintenance.

Description

Automatic Water System

Technical field the utility model relates to self water feeding (valve) device technique, and it is the Automatic Water System of the water level control of a kind of solar water heater or tank or large-scale water tower.

Background technique is at the water tank of solar water heater, life staying idle at home water or feedwater (valve) device of large-scale tank, the structure of this device (valve) that can be common, mainly be that transmission of mechanical shaft thick stick or employing solenoid valve are controlled automatically, or the structure of the combination of both combinations, the deficiency that they exist usually is a complex structure, volume is doted on greatly, and water intake velocity is slow, fault, maintenance rate height.

As China Patent No. 99202268.1, the patented technology of the water feed apparatus of known a kind of automatic control water level is installed diaphragm plate in its inlet valve, barrier film and spool, big piston, thin valve gap and spring, by the small piston of penstock connection float-controlled valve, the package unit member is many, connects complicated.

Chinese patent CN1354308A and for example, a kind of water intake equipment for water tower new technology is disclosed, the technological scheme that adopts mechanical transmission to combine with electromagnet, floating drum and buoy are through buoyancy of water, make drive link drive electromagnet and inhale, close, the water inlet of control water valve matrix, driving component has constrictor, swing arm and continuous motion stem, the installation difficulty of water valve matrix is also big.

Summary of the invention the utility model is big in order to solve this field feedwater (valve) device volume, and complex structure and provide a kind of simple and compact for structure is convenient to maintenance, stable Automatic Water System.

Water supply device of the present utility model include casing, float, valve body, valve rod and spool and advance, outlet pipe, on the circular or oblate casing, connect valve body and intake pipe and outlet pipe down respectively, valve body has one group of at least two water outlet, inner chamber connects valve rod, one end of valve rod with put the bracket that the inner chamber that fits over the float in the casing is connected and join, the invention characteristics are that the body cavity head puts and be furnished with the spool that circle has the discharge orifice, circular valve rod global design is that head end is a cylindrical body, what it linked to each other with cylindrical body down is trapezoidal cylindrical body, what link to each other with trapezoidal cylindrical body is cylindrical body, what link to each other with cylindrical body is trapezoidal cylindrical body, what link to each other with trapezoidal cylindrical body is cylindrical body, the inner chamber of valve body is corresponding with the shape of valve rod, be cylindrical cavity from top to bottom, trapezoidal cylindrical cavity and cylindrical cavity have one group of at least two water outlet on the valve body.Bracket central authorities are provided with circular hole, and the one group of rib in the outside connects the inwall of float inner chamber.Attaching has cone screw in the inner chamber of intake pipe.

The technique effect that the utility model manifests is: change the matching gap between valve rod and the valve body, the corresponding size of the water outlet of spool discharge orifice and valve body, can increase or reduce water flow automatically, and can prevent contaminant particles and sludge blockage, break down, spool and cone screw also have to be regulated the pressure of water inlet, adapts to different intake pressures, increases the working stability of this device.Float drives valve rod vertical lift, opening and closing water source, its reliable operation with buoyancy of water, stable, the member of whole device is installed connection easily, and is not easy to wear, long working life, dismounting and change valve body and cleaning spool or valve rod are convenient, save time, be convenient to maintenance, this device is simple in structure with respect to another advantage of existing similar technological scheme, with low cost, easily promote supporting use.
