Abstract

The utility model discloses a water-feeding device used for a solar-power water-heater, comprising a water-feeder and a water-drainer. The water-feeder comprises a three-way, a water-feeding valve, a solenoid valve, a draining valve, a twist spring, a revolving handle and a swaying bar. The solenoid valve receives the signals sent by the water-full signal-detecting port which is arranged below the water-storing barrel, so as to make the swaying rod drive the revolving handle to close the water-feeding valve and to simultaneously push the erect-bar of the start-and-stop switch of the draining valve to start the draining valve to realize the draining. The water-drainer comprises two solenoid valves, a water inlet, a water outlet, a draining valve piece and a sealing ring. The iron-core of the solenoid valve removes the draining valve piece to start or stop the water-drainer, when the draining-valve piece stops, the outer air enters the valve cavity from an air-feeding hole at the lower end of the iron core of the solenoid valve to drain the rest water in the water-draining pipe. The utility model can automatically drain the rest water in the feeding or draining pipe of the water-heater, so the frozen-trap of the water pipe can be effectively avoided. The utility model matches with the solar-power water-heater.

Description

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.

The installation instructions of water inlet device, water outlet device:

The water inlet device is loaded on indoorly for ease of operation, and water outlet device is loaded on outdoor, is positioned at water heater water butt below.

Contrast Fig. 3, water inlet pipe 23 is received the water inlet pipe 1 among Fig. 1 downwards, upwards receives

water inlet pipe

21, and 21 of water inlet pipes are to insert water butt 20 from water butt overflow pipe 22, water butt overflow pipe 22 links to each other with overflow pipe 24, overflow pipe 24 is provided with overfall 28, and the overfall 28 belows water pipe 30 that runs in, drainpipe 30 are provided with the full signal of telecommunication detecting head 29 of water, water butt outlet pipe 25 is received water butt 20, by water outlet device 26, pick out water pipe 27 downwards, outlet pipe 27 is received on the water appliance again.

Note during installation, the installation of water inlet pipe must reach two conditions: (1) is contained in water inlet pipe 21 more than the peak level of solar energy water butt 20, ponding and unlikely the water storage inner bucket water is drained in the water inlet device emptying water inlet pipe in the time of so just guaranteeing water inlet end, this installation method is exactly that water inlet pipe 21 is inserted from overflow pipe 22, but must guarantee effective overflow sectional area, general spilling water external tapping interior diameter is 15～16mm, as calculated, water inlet pipe 21 external diameter maximums are not more than 10mm, and internal diameter is not more than 8mm, just can satisfy the needs of overflow, even under the malfunctioning situation about can not close of water inlet device, also can guarantee the safety of solar water heater, can part of damage, it is curved to avoid occurring the U word when (2) install water pipe, and causes ponding in the pipe, because solar water heater generally all is contained in the higher position of roof, therefore realize than being easier to when mounted.

The course of work explanation of water inlet device, water outlet device:

Contrast Fig. 1, when inlet valve 8 is in the closed position, rotary handle 5 is in dotted line position, when water butt 20 needs water inlet, as long as rotary handle 5 is promoted about 90 °, rotary handle 5 other ends then promote the gib head of fork 6, make upwards swing of fork 6,7 of magnetic valves pin fork 6 under the effect of spring, also be lockable during rotary handle 5 revolutions simultaneously, at this moment source water enters from water source tube 9, gives water butt 20 water inlets continually by inlet valve 8, and water was through water butt overflow pipe 22 when water was filled with, expire signal of telecommunication detecting head 29 through overflow pipe 24 to water again, make circuit obtain the signal of telecommunication, make magnetic valve 7 rapid adhesives, rotary handle 5 under the effect of torsion spring 4, break away from fork 6 controls through the circuit amplification, rotate to dotted line position among Fig. 1, close inlet valve 8 rapidly, promote the emptying valve block 13 that tappet 10 is opened exhaust-valve 33 simultaneously, at this moment water inlet pipe 1 just and drainpipe 11 communicate, ponding in the water inlet pipe 1 is discharged by drainpipe 11, till the emptying.If have a power failure during water inlet, water butt 20 water are full to be overflowed from overfall 28 through overflow pipe 24, can realize closing inlet valve 8 with the iron core that pulls moving electromagnetic valve 7, ponding in the water inlet pipe 1 of emptying simultaneously; When temperature is higher than 0 ℃,, can realize the not interior ponding of comb as long as the exhaust-valve 33 of tappet 10, drainpipe 11, pipe joint 12, emptying valve block 13, spring 32 compositions is removed.

Contrast Fig. 2 when water appliance needs water, only needs by driving button, at this moment magnetic valve 14 is connected adhesive, moves on the emptying valve block 18, and water outlet device is opened, while magnetic valve 15 pins magnetic valve 14 under the effect of spring the unlikely whereabouts of iron core, the water in the water butt 20 continue to flow to water appliance; When needs are closed water outlet device, as long as by closing button, magnetic valve 15 is connected adhesive, emptying valve block 18 is closed rapidly under the effect of spring 34, because of the iron core lower end of magnetic valve 14 has air admission hole 40, a corresponding with it hole on the valve body, outside air is entered the valve pocket of emptying valve block 18 bottoms by air admission hole 40, water in the outlet pipe 27 that joins with delivery port 19 flows out naturally, does not also have ponding.If have a power failure when needing water, the hand switch by magnetic valve 14 and magnetic valve 15 can make water outlet device work equally.
