Abstract

The utility model relates to a valve which can automatically close water after the water in a solar energy water tank is full. The valve is an L shaped handle which is arranged on a ball valve, and a plastic bucket of a built-in siphon is suspended on the handle. The water is injected into the plastic bucket via a return pipe after the water in the solar energy water tank is full, and the valve is made to automatically close by using the lever of the L shaped handle, the plastic bucket and the gravitational function of the water in the plastic bucket.

Description

Water automatic shutoff valve on the solar energy

Affiliated technical field

When the utility model relates on the solar energy water, if water tank has expired the water saving fixtures that can cut out the water supply valve door automatically.Especially can transform existing old-fashioned solar energy water supply valve.

Background technique

At present, known solar energy water supply valve is the artificial hand dynamic formula mostly, after promptly the water in the solar water container has been expired, by closing water supply valve manually.Forgotten and close water supply valve that will waste a large amount of water, particularly China is a lack of water big country if the water in the water tank of solar energy has been expired back people, using water wisely is a state basic policy.Water is completely can close automatically by water on some novel solar energy in addition, but design is complicated, and maintenance bothers, and can not transform existing old-fashioned solar energy.

Summary of the invention

Can not close or design complicated deficiency automatically in order to overcome existing solar energy water supply valve, the utility model provides water automatic shutoff valve on a kind of solar energy, this water supply valve can automatically be closed the water supply valve door after the water in the water tank of solar energy has been expired, using water wisely, and can transform easily existing old-fashioned solar energy water supply valve, reforming cost is low.

The technological scheme that its technical problem that solves the utility model adopts is: change into the handle of original last water polo valve L shaped, end at handle hangs a gravity bucket again, the water of backflow injects bucket after the water tank of solar energy has been expired, and utilizes the lever principle of L shaped handle of ball valve and the gravity of water and bucket automatically water supply valve to be closed.After valve was closed automatically, design had the syphon tube of a N shape in the gravity bucket, and it can automatically be drawn onto the water in the gravity bucket outside the bucket, used so that continue next time.

The beneficial effects of the utility model are, can work as to close automatically after water in the solar water container has been expired that solar energy water supply valve door, particularly people have been forgotten throttle down or when staying out, can reach using water wisely ground purpose.And can transform old-fashioned solar energy water supply valve low-cost, easily.
