A communicating pipe which is arranged below the valve seat and is used for communicating the valve body and the water pipe is provided with the one-way valve which can cause water to flow out but not to flow in. The one-way valve is communicated with the water-supplying pipe or the water return pipe. The utility model has the advantages of flexible control of automatic water supply, convenient operation, and pipe materials saving.
Description
One, technical field:
The utility model relates to a kind of solar water heater single tube automatic water-supply apparatus.
Two, background technology:
The water-supply apparatus of the plain edition solar water heater that generally uses on the market is made up of a water inlet pipe and an overflow pipe that is connected in water-heater water tank top that is connected in the water-heater water tank bottom.When last water process water-heater water tank water was full, water reminded the user that water intaking valve is closed from the overflow pipe outflow or by at overflow pipe warning device being installed, thereby must someone wait for when last water.It is tired with extend protection to bring some inconvenience to the user.Have only a few high-grade automatic solar water heater to have the function that last water water is closed completely automatically at present, the full self closing device of its water is mounted on the water-heater water tank, or an external ball float case, or at ball-cock assembly of the inner installation of water tank.External ball float case is installed complicated, and built-in ball-cock assembly is installed mode and safeguarded cumbersome.
Three, summary of the invention:
The purpose of this utility model is for overcoming the defective of above-mentioned solar water heater water-supply apparatus, having designed a kind of solar water heater single tube automatic water-supply apparatus.
The technical solution of the utility model realizes in the following manner:
Solar water heater single tube automatic water-supply apparatus, by water tank, float liquid level control valve, upper hose, go up water retardation valve, form with water valve, it is characterized in that the design of float liquid level control valve is connected in upper hose or is connected in return pipe by ball-and-seat at the vertical diameter of water tank orientation, outlet at bottom, be provided with on the indoor water pipe with being in charge of and control valve of hot water being in, below being in charge of, be provided with water retardation valve; The float liquid level control valve is cylindrical, form by the float of upper end in the valve body, middle control lever, the taper valve core under its bar, to be that one is vertical with control lever erect at fluid level control valve body center float, taper valve core cooperates with conical seat set at the bottom of the fluid level control valve, fluid level control valve body bottom links to each other with water tank bottom is vertical, be provided with one and can go out the ball-and-seat that can not advance on the communicating pipe of following valve body of valve seat and water pipe, ball-and-seat directly is communicated with last water or return pipe.
Last water retardation valve body is cylindrical or square, wherein be provided with the cross cavity, valve body and valve head are made as one, valve head is cylindrical, its top internal diameter is greater than the bottom internal diameter, which is provided with male thread, cooperate with the box thread of the valve gap that is provided with centre bore, going up of the vertical cavity of cross is outlet, be import down, import and export are equipped with box thread, be provided with cylindrical spool in the horizontal cavity, its middle part diameter is less than two diameter, equal the diameter of valve rod, the valve rod top is provided with radio button, its diameter is slightly less than the internal diameter on valve head top, between knob bottom and valve head internal diameter reducing step, be provided with helical spring, between water inlet and lower valve body cavity, be provided with intercommunicating pore.
The utility model is compared with the two-tube water-supply apparatus of prior solar water heater has automatic loading water control flexibly, and easy to use, the characteristics of saving tubing have wide promotion prospect.
Four, description of drawings:
The scheme of installation of Fig. 1-water-supply apparatus of the present utility model;
Fig. 2-the utility model is the mounting structure schematic diagram on water tank;
The structural representation of Fig. 3-last water retardation valve.
Five, the specific embodiment:
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description: form by water tank 1, float liquid level control valve 3, upper hose or return pipe 8 with water valve 4.It is characterized in that float liquid level control valve design in the vertical diameter of water tank orientation, be connected in upper hose 8 or be connected in return pipe 8 by ball-and-seat, be provided with on the indoor water pipe with being in charge of and control valve 4 of hot water being in, below being in charge of, be provided with water retardation valve 6; The float liquid level control valve is tubular, and by the float 3-1 of upper end in the valve body 3, middle control lever 3-2, the taper valve core 3-3 of control lever lower end form.To be that one is vertical with control lever erect at the center of fluid level control valve body float, and the set conical valve seat 3-5 in taper valve core and fluid level control valve bottom cooperates, and the bottom of float liquid level application valve body links to each other with water tank bottom is vertical.Be located at one and can go out the ball-and-seat 3-4 that can not advance on the communicating pipe of the valve body of valve seat bottom and water pipe, ball-and-seat directly is communicated with last water or return pipe, is in indoor upper hose position in its bottom and is provided with the water time in 6 controls of water retardation valve.
When wanting to add water to solar water heater water storing tank 1, only need press water button 6-4 on the water retardation valve 6, at this moment, last water retardation valve is opened, current withstand the spool mid portion because of the pressure effect promotes multiaspect valve ball 6-7, current can enter solar water heater water storing tank 1 by last water retardation valve 6 along upper hose, float 3-1 drives on the taper valve core 3-3 by control 3-2 and moves when water storing tank water is full, thereby close valve seat 3-5, at this moment, the hydraulic pressure in the last water retardation valve pocket is consistent with water inlet pipe 8 hydraulic pressure, water is no longer mobile, the multiaspect valve ball runs out of steam, and because of gravity fall, spool 6-3 resets under the reaction of spring 6-6 and hydraulic pressure.Thereby sealing upper hose 8, at this moment because solar water heater water storing tank water is full, upward water retardation valve 6 cuts out automatically, water in the solar water heater water storing tank can not flow out from retardation valve 6, so flow out from ball-and-seat 3-4, the user opens hot water gate 4 hot water and flows out and can use.The user presses button like this, its water filling automatically, and water is closed completely automatically, has saved material, has made things convenient for the user.
