Embodiment 1

[0015] The water leakage protection valve in the present embodiment consists of casing (1), impeller (4), float (7), piston (8), briquetting block (9), clamping rod (10), lever (11), gear (12 ), eccentric wheel (13), reset handle (14) and reduction gear (such as figure 1 shown) (as image 3 shown). The transmission gear on the impeller (4) meshes with the primary transmission gear (6) in the reduction gear set, and the impeller (4) drives the reduction gear set to decelerate and rotate step by step under the promotion of water flow.

[0016] Pull up the briquetting block (9) with the reset handle (14). At this moment, one end of the clamping rod (10) pushes the light end of the clamping rod (10) into the lower part of the briquetting rod (9) under the action of gravity, and the briquetting block ( 9) The water leakage protection valve is stuck and fixed (such as image 3 shown).

[0017] Set a water flow value (such as the gear of 2 tons of water) for the water leakage pro...

Abstract

The invention relates to a water leakage protection valve. The position of a piston (8) in an outer casing (1) is consistent to the direction of gravity, the density of floats (7) is less than that of water, the floats (7) are serially connected to a rod of the piston (8), and the rod of the piston (8) penetrates through a lever (11); and a pressing block (9) is a metal weight and is installed right above the top end of the rod of the piston (8), a gear (12) and an eccentric wheel (13) are installed on the lever (11) and are mutually connected to the same axis in series, a clamping rod (10) penetrates through the eccentric wheel (13), and the gravity center of the clamping rod (10) moves to one end. The automatic resetting, automatic zero adjustment and automatic closing of flow of the water leakage protection valve are realized completely through the self gravity and buoyancy of objects, and springs are completely omitted.

Description

technical field [0001] The invention relates to an anti-leakage valve, in particular to a mechanical device for detecting water leakage and automatically cutting off to prevent water leakage. Background technique [0002] In the utility model patent of the patent (2009201557233), there are the following deficiencies in a mechanical device that is used to find water leakage and automatically cut off to prevent water leakage; the spring in the installation will shorten the life of the spring due to being soaked in water for a long time, which directly affects Mechanical reliability. Contents of the invention [0003] The invention provides a water leakage protection valve to overcome the deficiencies in the utility model patent (2009201557233). [0004] The water leakage protection valve of the present invention is composed of a casing, an impeller, a float, a piston, a briquetting block, a locking rod, a lever, a gear, an eccentric wheel, a reset handle and a reduction gea...
