Summary of the invention

For overcoming the above problems, the utility model provides anti-down flow pattern full water warning automatic stop arrangement, and it meets hydraulic pressure when last water low excessively, can stop automatically, with anti-backflow; Also stop to go up water automatically with the whistling warning when last water is full.It is cheap, economy and durability, and installation and maintenance are convenient, do not rely on power supply.

The technical scheme of the utility model is: designed special valve body, the valve pocket lower end is a water inlet, the check valve that has the ability easy on and off to move in the lower valve chamber of valve body; During last water; Check valve is washed open, and water flows to the solar energy upper hose through the delivery port of valve pocket side, when the hydraulic pressure reduction can not be gone up water; Check valve moves down and closed, and water can not flow backwards.Uuper valve chamber is a T font valve pocket, in T font piston is arranged, upper wall has limited post in the uuper valve chamber, port is a flush connection, connects the overflow pipe end opening, other port communicates with blowing a whistle to manage.When waterborne expiring, the downward flowing water of overflow pipe is pressed towards the pipe of blowing a whistle with the interior air of valve pocket in the pipe.Blow a whistle the pipe lower end straight-through valve is arranged, there is the ball float cap upper end, in the ball float cap ball float is arranged, the ball float cap loudspeaker flute that connects suitable for reading.When air-flow rushes at when pipe of blowing a whistle, the straight-through valve of lower end is a closure state, and air-flow rises and washes ball float open and flow out through the loudspeaker flute, and the loudspeaker flute is blowed.After overflow water gets into valve pocket, get into the pipe of blowing a whistle then, the pipe water level of blowing a whistle rises, and ball float is held up, and it is suitable for reading to block the ball float cap, and the loudspeaker whistling stops.In the time of when water rises to two meters scopes in overflow pipe within, T font piston produces big pressure downwards, and it is closed with check valve to glide, and accomplishes and cuts off the water automatically.

Owing to adopt above scheme, can go up water easily, need not to wait, save time, do not worry aqueous reflux.Ingenious, rational in infrastructure because of the utility model design, so cost is low, long service life, do not rely on power supply, be beneficial to universal.

Description of drawings

Accompanying drawing is the structural representation of the utility model.

Among the figure: 1 water inlet, 2 check valves, 3 lower valve chambers, 4 delivery ports, 5 valve bodies, 6T font piston, 7 uuper valve chambers, 8 left limit posts, 9 right limit posts, 10 flush connections, 11 loudspeaker flutes, 12 ball float caps, 13 ball floats, 14 blow a whistle pipe, 15 straight-through valves, 16 pores.

The specific embodiment

With reference to accompanying drawing, water inlet (1) connects running water pipe, and delivery port (4) connects the solar energy upper hose bottom, and flush connection (10) connects solar energy overflow pipe lower port.When opening on the valve water, current are washed check valve (2) open, flow to the solar energy upper hose through lower valve chamber (3), delivery port (4).T font piston (6) in the valve body (5) is upwards slided by the active force of the interior water of lower valve chamber (3), by left limit post (8) and right limit post (9) stop.The effect of pore (16) is T font piston (6) air inlet or exhaust when sliding up and down.The other end of uuper valve chamber (7) communicates with the pipe (14) of blowing a whistle, and pipe (14) lower end of blowing a whistle is straight-through valve (15), and the upper end is ball float cap (12), and ball float (13) is arranged in the ball float cap (12), on connect loudspeaker flute (11).

In last water process, tap water hydraulic reduces, in the time of can not going up water, and check valve (2) auto-closing, water does not flow backwards, and check valve (2) is opened water in the continuation voluntarily when treating the hydraulic pressure rising.When the solar water container filling up water; The downward flowing water of overflow pipe, the air in the pipe and the air on uuper valve chamber (7) top are compressed by current, flow the pipe (14) of blowing a whistle; Blow a whistle the straight-through valve (15) of pipe (14) lower end for closed condition; Therefore dash on the air-flow, discharge, loudspeaker flute (11) warning of blowing a whistle through loudspeaker flute (11).When water was filled with the top of uuper valve chamber (7) and blown a whistle pipe (14), it is suitable for reading that ball float (13) come-up is blocked the ball float cap, and water does not outflow, and whistling stops.At this moment, the water of lower end rises rapidly in the overflow pipe, when water-column is no more than two meters; T font piston (6) has received the big pressure of overflow water, and to lower slider, check valve (2) is pressed in T font piston (6) lower end; Final check valve (2) is compacted and closed, accomplishes and cuts off the water automatically.

Last water is closed water supply valve after accomplishing, and opens straight-through valve (15), and it is subsequent use that water is put into washbowl.When discharging water, T font piston (6) upwards slides, until overflow water has been put.Close straight-through valve (15), in order to going up water next time.

About the operation principle of T font piston, be necessary to be described further: the circular diameter of T font piston upper surface is 5 times of lower surface circular diameter; The ratio that is their area is 25: 1 because the inner pressure of water is directly proportional with the degree of depth of water, water to the pressure of object be contact area with the pressure of water become to amass; So 2 meters high water columns are equivalent to the active force of 50 meter water columns to the lower surface to the pressure of T font piston upper surface, obviously; The height of upper hose can not surpass 50 meters, and the water column that the pressure of running water is supported can not surpass 50 meters yet, therefore in overflow pipe; Liter waterborne is during less than 2 meters; T font piston has just received downward pressure, and glides and compress check valve, accomplishes and cuts off the water automatically.

The above only is the special case that the utility model is used for the solar water heater water-feeding system, also can design the product of plurality of specifications by this technical scheme; Be used for water on the water tower; Water on the pond on the mountain, the watering flowers automatically of eminence flower bed, roof cement face maintenance in the flat-topped building building.All professional and technical personnel on the utility model technical scheme basis, extend out conspicuous variation or replacement are still at the row of the protection domain of the utility model.
