Abstract

The utility model provides a water-refilling control device, wherein a non-return valve is arranged at the water inlet of a water tank, a float is arranged on the overflow port of the water tank, the float is connected with the non-return valve at the water inlet through a rope, a non-return valve is arranged on a water-refilling pipe, a ball valve is arranged below the non-return valve on the water-refilling pipe, a three-way valve is arranged below the ball valve, a three-way valve is arranged between the non-return valve on the water-refilling pipe and the non-return valve at the water inlet of the water tank, the branch end of the three-way valve below is connected with a cooling water pipe, the branch end of the three-way valve above is connected with a hot water pipe, and the cooling water pipe and the hot water pipe are connected through a water mixing valve. The use of the device can prevent the overflow of tap water, thereby saving a large quantity of tap water. The utility model is low in manufacturing cost, free from maintenance and easy to operate. The use of the utility model involves opening the tap water refilling valve before going out in the morning and closing the tap water refilling valve before taking shower at night.

Description

A kind of water-supply control device of solar water heater

Technical field

The utility model relates to a kind of applied technical field of water-supply control device of solar water heater.

Background technology

What present regular solar water heater water-supply apparatus on the market was used is to control water on the water tank by the overflow pipe backwater, needs to wait for for a long time, may forget sometimes, removes to close running water water supply valve door again, has caused some no small wastes.

What water used on the solar water heater of another kind of top grade then is the device that utilizes electronics, closes running water water supply valve door by magnetic valve, expense height, maintenance trouble.

The utility model content

In order to save water time and the waste of avoiding water, the utility model provides a kind of water-supply control device of solar water heater.

The utility model is provided with a valve in the water inlet of water tank, described valve comprises the valve body that is provided with valve pocket, valve seat, cover plate, one valve seat is set in the valve pocket of described valve body, be hinged a cover plate in described valve seat right side, on the top of described cover plate the lanyard ring is set, a float is set on the overfall of described water tank, float is connected by rope with retainer ring on the described cover plate, a check valve is set on upper hose, one ball valve is set below the check valve on the described upper hose, one threeway is set below described ball valve, between the check valve at check valve on the described upper hose and water tank inlet place, a threeway is set, the branch end of the threeway of described below connects cold water pipe, and the branch end of the threeway of described top connects hot-water line, and described cold water pipe mixes water valve with hot-water line by one and is connected.

The cover plate of the valve of water tank import department keeps parallel with flowing to of water when last water, be unlikely to be shut with assurance by water impact, once more the length of rope and the height of overfall are done a setting, float rises when water is full, and the pulling rope covers cover plate, reaches the purpose that blocking-up continues to go up water, after last water is blocked, check valve on the upper hose also can be closed, and can guarantee further that like this water can not flow backwards, and installs after this covering device, not having again running water to run overflows, can save the running water of enormous amount, cost is low, and is non-maintaining, easy and simple to handle, the front opening running water water supply valve door of going out morning, the shower of going home evening then need be closed running water water supply valve door.

In addition, water inlet pipe of the present utility model and outlet pipe are same pipeline.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is the structural representation of water tank of the present utility model import department valve.

Among the figure, 1, float, 2, valve, 3, check valve, 4, mix water valve, 5, water tank, 6, rope, 7, upper hose, 8, overfall, 9, ball valve, 10, threeway, 11, threeway, 12, cold water pipe, 13, hot-water line, 14, valve body, 15, valve seat, 16, cover plate, 17, retainer ring.

The specific embodiment

As Fig. 1, shown in 2, the utility model comprises float 1, valve 2, check valve 3, mix water valve 4, water tank 5, rope 6, upper hose 7, overfall 8, one valve 2 is set in the water inlet of water tank 5, valve 2 comprises the valve body 14 that is provided with valve pocket, valve seat 15, cover plate 16, one valve seat 15 is set in the valve pocket of valve body 14, be hinged a cover plate 16 in valve seat 15 right sides, on the top of cover plate 16 lanyard ring 17 is set, one float 1 is set in the overfall 8 of water tank 5, one check valve 3 is set on upper hose 7, ball valve 9 is set below the check valve on the upper hose 3, threeway 10 is set below ball valve 9, threeway 11 is set above check valve 3, the branch end of the threeway 10 of below connects cold water pipe 12, the branch end of the threeway 11 of top connects hot-water line 13, and cold water pipe 12 is connected by mixing water valve 14 with hot-water line 13.

The cover plate 16 of the valve 2 of water inlet is that a float 1 by gap 8 places utilizes rope 6 to affect, float 1 rises when the water of 5 li of solar water containers is expired, drive the cover plate of rope 6 pulling valves 2, add the last water pressure of running water, close check valve 2 and reach the purpose that water is gone up in blocking-up.
