Description

Water tank is the water automaton up and down

Technical field

The utility model relates to a kind of water tank water automaton up and down, and the water up and down of particularly suitable solar water heater water tank is controlled automatically.

Background technology

Solar water heater generally adopts to connect two water pipes on water tank in order to solve water problems up and down at present, wherein keeps supplying down water usefulness for one, is connected water tank bottom; Another root is connected water tank upper as overflow pipe, plays completely warning effect of water.Be the waste of anti-sealing, whether the exit of always constantly observing overflow pipe when people go up water usually there are flowing out, valve-off behind the wait filling up water, but the last water time, length was indefinite with the pressure difference of running water, and when hydraulic pressure is low, also there is the hot water reflux problem, allows the user feel inconvenience deeply.The employing electronic sensor that also has, Electromagnetic Control, but because of the reasons such as quality of environment and components and parts usually control malfunctioning, and maintenance price costliness.

Summary of the invention

The purpose of this utility model provides a kind of water tank water automaton up and down, makes it can solve water tank automatic water and hot water reflux problem up and down, can save overflow pipe simultaneously, reduces cost.

The utility model is at deficiency of the prior art, water supply and drainage mechanism to solar water heater makes improvements, this device comprises indoor, outdoor two large divisions, indoor section is to utilize existing device to install check valve additional before water supply valve, only permitted cold water toward the upper reaches, prevent that hot water is back to the running water pipe network, outdoor section includes by first two valve bodies that threeway is joined together to form of macaroni yarn, endoporus valve nozzle coning, airflow fence, spool, valve rod, floating drum, water level pipe, direct and the plug of reducing, valve nozzle is installed in the following threeway of valve body, and be fixed by the plug of netted tubular airflow fence by the closed valve under shed, water level pipe and valve body directly are communicated with by reducing, the direct center of reducing is provided with throttle orifice, valve rod one end passes throttle orifice and connects the floating drum that is positioned at water level pipe, and an end passes valve nozzle and connects the spool that is arranged in airflow fence.

Automatics described in the utility model has solved water tank automatically up and down water and hot water reflux problem, can save overflow pipe simultaneously, reduces cost, and the user also can wait for valve-off behind the filling up water again, and the overflow of anti-sealing economizes on resources simultaneously.

Description of drawings

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

Among the figure: 1, floating drum, 2, water level pipe, 3, valve rod, 4, throttle orifice, 5, go up threeway, 6, the macaroni yarn head, 7, valve nozzle, 8, water inlet, 9, airflow fence, 10, threeway down, 11, plug, 12, reducing is direct, and 13, delivery port, 14, sealing ring, 15, spool, 16, counterweight.

The specific embodiment

In conjunction with the accompanying drawings, specify embodiment of the present utility model.

As shown in Figure 1, outdoor section includes by a macaroni yarn head 6 two threeways 5 and 10 valve bodies that are joined together to form, endoporus valve nozzle 7, airflow fence 9, spool 15, valve rod 3, floating drum 1, water level pipe 2, reducing direct 12 and plug 11 coning.Valve nozzle 7 is installed in down in the threeway 10 and is connected with macaroni yarn head 6 lower ends, be provided with sealing ring 14 between valve nozzle 7 and the macaroni yarn head 6, and be fixed by the plug 11 of netted tubular airflow fence 9 by the closed valve under shed, macaroni yarn head and endoporus valve nozzle coning can be structure as a whole, and what adopt in the present embodiment is isolating construction.Water level pipe 2 is communicated with by the upper shed of reducing direct 12 and last threeway 5, direct and the last threeway of reducing can be structure as a whole, what adopt in the present embodiment is isolating construction, the direct center of reducing is provided with throttle orifice 4, valve rod 3 one ends pass throttle orifice 4 and connect the floating drum 1 that is arranged in water level pipe 2, one end passes valve nozzle 7 and connects the spool 15 that is arranged in airflow fence 9, spool top is spherical colloid, the bottom connects counterweight 16, valve rod and being connected of spool, to be valve rod passed palintrope from the colloid center spool colludes, and colloid spool 15 umbos tightly assign in the centre bore of counterweight 16.This automatics indoor section is to utilize existing device to install check valve additional before water supply valve, is only permitted cold water toward the upper reaches, mustn't flow backwards by hot water.Outdoor section vertically is installed in the water tank next door, the height of water level pipe is greater than the height of water tank, the height of floating drum control is not more than the height in water tank overflow hole, and this automatics delivery port 13 connects the delivery port of water tank, and the level height of delivery port 13 is not higher than the delivery port height of water tank.When water tank was anhydrous, spool 15 dropped on the bottom of airflow fence 9 because of the gravity of counterweight 16, and this moment, the position of spool 15 was lower than water inlet 8 certain altitudes, and floating drum 1 also drops on the bottom of water level pipe 2.When being on the water tank during water, open indoor water supply valve door, water upwards enters down the water inlet 8 of threeway 10 by indoor check valve, the airflow fence 9 of flowing through then, valve nozzle 7 enters threeway 5, enter water tank by delivery port 13, simultaneously by throttle orifice 4 water in water level pipe 2 inter-syncs, floating drum 1 slowly rises, floating drum drives spool 15 by valve rod 3 and rises, the length control water level of regulating valve stem, hemispherical colloid spool 15 enters complete shutoff intake tunnel in the conical valve nozzle 7 when reaching designated water level, and close aquaporin because the reliable effect of differential water pressures is closed this moment, and water is stopped automatically.When hydraulic pressure was very low, floating drum will be buried slowly, and while buoyancy also will add ambassador's elastic sphere gradually and seal tightly shutoff intake tunnel, reached to close fully and closed water.When discharging water, water in upper and lower conduit road and the following threeway is at first outflow under the gravity effect, forms negative pressure in pipeline, and spool overcomes floating drum under the effect of the gravity of counterweight and negative pressure buoyancy descends automatically, make valve open form down aquaporin, thus the problem of water about solving automatically.

Described airflow fence plays the effect of restriction spool movement locus.

Described throttle orifice plays the effect that water tank and water level pipe are gone up water synchronously.

The valve body that described valve body can be structure as a whole, what adopt in the present embodiment is isolating construction.
