VALVE FOR AUTOMATIC SHUTOFF OF WATER WITH EXTERNAL SENSOR Russian patent published in 2011 - IPC E03C1/05 

FIELD: construction.

SUBSTANCE: valve comprises an external sensor 1 of water availability, at the same time in a body 3, having a faceted shape, there is a support plate 4, having the shape similar to the shape of the body 3, where a drive screw 5 is fixed with an angle of thread inclination to the axis of rotation making less than 30 degrees, and around the screw 5 there is a spring 6, resting at one side against the support plate 4, and at the other side - against a cover 7 of a bearing 8, placed onto the screw 5. The bearing 8 with its lower cover 9 rests against a nut 10 of the screw 5, fixed on an internal body 11, having two and more pins with a mushroom head 13 on a flange 12. The body 11 with its flange 12 rests against the bearings 14, 15, which limit its displacement along the axis of the body 3 and retained in the body 3 with the brackets 16, 17. The mushroom heads 13 of the pins enter a steering control 18 of the valve, and via a window 20 in the body 3 a lever 21 of the first or the second type with its sear 22 retains a body 11 against rotation, having slots 23 on the flange 12. The second end of the lever 24 rests against a movable stop 25, connected with a slider 26 of the water sensor 2 with a rope 27, where there is an incompressible shell 28, which rests with one end 29 against a bracket 30 on the body 3, and with the second 31 end - against the body of the water sensor 2, inside which there is a spring 33, which rests against the slider 26, retained from displacement by the sear 34 of the lever 35 of the first or second type of the water sensor 2 via a window 36 of the body 32 of the water sensor. The second end 37 of the lever 35 rests against a readily soluble plate 38. At the same time the lever 35 is arranged in a bracket 39 installed on the body 32 of the water sensor 2. Also in the body 3 there are slots for the valve with pipes 40 and the steering control 18 and a hole 41 for a special screw 42.

EFFECT: higher safety and reduced prime cost.
