Automatic-closing valve in the time of leaking water

Abstract

The invention provides a valve which can automatically close in the condition of water leakage, and comprises a hand valve which can be closed or opened by rotating the plug of the hand valve by 90 degrees, and a valve self-closing mechanism. The valve self-closing mechanism is provided with an encloser. A valve shaft pull handgrip, one end of which is connected with the shaft of the hand valve, is arranged on the left side inside the encloser. A helical spring is arranged between the valve shaft pull handgrip and the upside inside the encloser. An elastic locking piece, which can lock the valve shaft pull handgrip, is arranged in the encloser. The elastic locking piece is connected with a locking piece bracket and is articulated with a vertical flashboard. Splints are arranged on both sides of the flashboard. An upper interconnection board and a lower interconnection board are articulated between the flashboards. A slide bar protruding beyond the upper end and the lower end of the encloser vertically is arranged on the right side of the encloser. The lower end of the slide bar is connected with a floating ball. An oscillating bar, the left end of which is articulated with the left side of the bottom plate inside the encloser, is arranged on the upside in the encloser. The middle segment of the oscillating bar and the left end of the lower interconnection board are articulatedwith a long connecting rod. The right end of the oscillating bar and the middle segment of the slide bar are articulated with a short connecting rod. After water is leaked, the hand valve can be automatically closed by rotating the plug of the hand valve by 90 degrees to prevent accidents resulting from the leakage of the valve.

Description

technical field [0001] The invention relates to a water leakage automatic closing valve, in particular to a closing mechanism for a water leakage automatic closing valve. Background technique [0002] Manual valves have valves that can be opened or closed by rotating the valve core at an angle of 90 degrees, such as ball valves, plug valves, butterfly valves, etc. In the water supply system with manual valves that can be opened or closed by rotating the valve core at an angle of 90 degrees, sometimes it will stop. For water, if the above-mentioned valve is opened when the water is cut off, and there is no water after the valve is opened, and the valve is forgotten to be closed, after the water supply is restored, the valve will leak water, and if the valve leaks water for a long time, it will cause adverse consequences. In the prior art, there is no manual valve that can be turned on or off at an angle of 90 degrees to realize the opening or closing of the spool that can be ...

Water, if the above-mentioned valve is opened when the water is cut off, and there is no water after the valve is opened, and the valve is forgotten to be closed, after the water supply is restored, the valve will run out of water, and if the valve runs out of water for a long time, it will cause adverse consequences

In the prior art, there is no manual valve that can be turned on or off at an angle of 90 degrees to realize the opening or closing of the valve core that can be automatically closed after running water
