Abstract

A main body of an automatic water-stopping device is formed from two rectangular boxes matching with each other inside and outside, which is connected with a water injection valve switch of a solar energy water heater via a draught rod to form a simple mechanical system. When the water heater is injected to be full, the water flows into a water box via a return pipe and the water in the water box increases gradually. When the water increases to a certain quantity, due to the action of the gravity, the water box moves down and draws the water injection valve switch via the draught rod to close the water injection valve. A water preventing rod is jacked up after an inner box falls down following which a water preventing valve moves up and dislocates. The water in the inner box flows down via a water discharging slot and flows into a standby container via an outlet pipe.

Description

Automatically the device of cutting off the water

Affiliated technical field

Novel a kind of device of cutting off the water, the definite a kind of device of cutting off the water that relates to solar energy of saying so of relating to of this use.

Background technology

At present, civil solar heat generally is by manually stirring the valve switch lever, carries out water filling and cuts off the water, and after water filling was full, user Chang Yin forgot closing valve and causes a large amount of water to run off for a long time from return pipe and steam vent, causes waste.The solar energy device of cutting off the water automatically is installed is the electronic type structure mostly even have, and its price height is installed the religion trouble, and is fragile.

Summary of the invention

Order of the present utility model provides the solar energy of a kind of simple in structure, cheap, dependable performance, the safe ready device of cutting off the water automatically.

The technical scheme that its technical problem that solves the utility model adopts is: utilize to flow into the gravity of a spot of normal backwater of the device main body inner box of cutting off the water automatically, by the draw bar water injection valve lever of leaving behind, valve-off stops water filling.Because inner box falls under the effect of backwater gravity, the bar that blocks water in the inner box is returned power jack-up, moves dislocation on the valve pad, and the sluicing mouth of pipe is opened, and backwater is promptly imported complementary tank from catch-drain by pure water pipe.Described inside and outside two suitable cuboid boxes constitute the device main body of cutting off the water automatically, be connected with solar water heater water injection valve switch lever by draw bar, constitute a simple mechanical system, when to the solar energy water filling, water completely back flows in the water box by return pipe, water in the water box constantly increases, when being increased to when a certain amount of because the gravity effect moves downward, when moving downward by draw bar pulling water injection valve switch, close water injection valve, reach the purpose that stops to go up water.The bar that blocks water after inner box falls is returned power jack-up, water stopping valve with on move dislocation, inner box water is then dirty by catch-drain, flows into complementary tank through outlet pipe.

The cuboid volume is the 800-1000 milliliter in described, and described length of draw bar is adjustable.

The utlity model has following advantage.

Even 1, close to forgetting after the solar energy water filling, treat will close automatically after waterborne expiring, can not cause a large amount of flowing water;

2, do not need other energy, exterior power;

3, cost is low, simple to operation.

Among the figure 1, returning pipe joint, 2, the pure water pipe joint, 3, tapping pipe, 4, the valve rod that blocks water, 5, catch-drain, 6, axle bed, 7, the screw that tightens up without a head, 8, the rubber valve packing ring, 9, water injection valve switch lever axle center, 10, the water injection valve and the draw bar connecting axle hole circle heart, 11, draw bar through hole, 13, draw bar, 14, water injection valve, 15, outer water tank, 16, inner water tank.

The specific embodiment

The solar energy return pipe is connected with the utility model returning pipe joint 1, when giving the solar energy water filling with water injection valve 14 cocked one-tenth levels, water filling completely back flows into inner water tank 16 by return pipe, the water of inner water tank 16 constantly increases, when reach a certain amount of after, because the gravity effect moves downward, in moving downward process, draw water injection valves 14 by draw bar 13, water injection valve 14 is to move clockwise in the center of circle with water injection valve switch lever axle center 9, water injection valve cuts out when water injection valve 14 is transported to plumbness, stops water filling.Inner box falls under the effect of backwater gravity, and the valve rod 4 that blocks water of its inside is returned power jack-up, moves dislocation on the rubber valve pad 8, and tapping pipe is opened for 3 mouthfuls, and backwater is promptly imported complementary tanks from catch-drain 5 by pure water pipe 2.Entire work process is finished by a simple mechanical system.

Claims

1, a kind of device of cutting off the water automatically, it is characterized in that: nonmetal or can constitutes the device mechanical body of cutting off the water automatically by inside and outside two suitable cuboids, be connected with solar water heater water injection valve switch lever by draw bar, the water heater return pipe is connected to the pipe joint of cutting off the water automatically, and a backwater controller is formed by weep pipe and water stopping valve in the inner box bottom.

2, the device of cutting off the water automatically according to claim 1 is characterized in that: its draw bar utilizes the screw mandrel combination in fiber tube and two each tape spool holes of difference one end, constitutes the power rail that can regulate length.
