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
The present invention relates to a kind of water leakage preventing valve door, particularly a kind ofly be used to find the situation of leaking and cut off automatically prevent the mechanical device that leaks.
Background technique
Be used for finding the situation of leaking and cut off automatically preventing that the mechanical device that leaks from having the following disadvantages for the utility model patent of (2009201557233) provides a kind of in patent; The spring of the inside is installed owing to be immersed in the life-span that can shorten spring in the water for a long time, is directly influenced the reliability of machine work.
Summary of the invention
The invention provides a kind of protection valve that leaks and overcome the deficiency that exists in the utility model patent (2009201557233).
Of the present invention leak the protection valve by shell, impeller, float, piston, briquetting, screens bar, lever, gear, eccentric wheel, reset the handle and reduction gear form.Originally the drip-preventing function principle of protecting valve of leaking is the standard (this current value can be provided with according to the water situation of different home) of leaking as judgement with the disposable current value of protecting valve by leaking continuously; continuously the current value current that do not reach setting of the water flow by the protection valve that leaks stop by leaking the protection valve that make zero at once and restart to count flow, as long as disposable (can not there be any pause the centre) continuously the current value that reaches setting of the water flow by the protection valve that the leaks protection valve that leaks close automatically and prevent to leak.The present invention's automatically reseting of protection valve flow of leaking made zero and closed fully automatically by self gravity and buoyancy of object and realize, spring has all been omitted.
The invention has the beneficial effects as follows simple in structure, reliable operation.

Embodiment
The present invention piston (8) the position in shell (1) of protection in the valve that leak is consistent with gravitational direction, and the density of float (7) is littler and be connected on the bar of piston (8) (as shown in Figure 2) than water, and the bar of piston (8) passes lever (11).Briquetting (9) is rectified the top for the metal weight is installed in piston (8) masthead.Gear (12) and eccentric wheel (13) are installed in lever (11) and go up and be connected on mutually on the same axle.Screens bar (10) passes eccentric wheel (13), and the center of gravity of eccentric wheel (13) is (as shown in Figure 2) partially at one end.
Embodiment one
Leaking protection valve in the present embodiment is formed (as shown in Figure 1) (as shown in Figure 3) by shell (1), impeller (4), float (7), piston (8), briquetting (9), screens bar (10), lever (11), gear (12), eccentric wheel (13), reset handle (14) and reduction gear.Driving gear on the impeller (4) and elementary speed change gear (6) interlock in the train of reduction gears, impeller (4) drive the train of reduction gears rotation of slowing down step by step under current promote.
With reset handle (14) pull-up briquetting (9) at this moment screens bar (10) one ends under the effect of gravity, an end light in the screens bar (10) pushed briquetting (9) below, briquetting (9) is stuck and has fixed the protection valve that leaks and be in and open (as shown in Figure 3).
Be the disposable current value (as the gear of 2 tons of water) of valve of protecting by leaking continuously of protection valve setpoint that leaks; do not have current by the time be connected on piston (8) bar float (7) and under buoyancy function, drive piston (8) and rise to the top and upwards seal water outlet, piston (8) promotes lever (11) and rises and make the gear (12) that is installed in lever (11) one ends and the final stage gear (5) in the train of reduction gears be in separated state simultaneously.Eccentric wheel (13) is partial to an end under the effect of gravity, flow measurement is started from scratch (as shown in Figure 3).
Impeller when having current to pass through (4) drives the train of reduction gears rotation of slowing down step by step under current promote, current promote piston (8) and move downward, at this moment piston (8) unclamps the lever (11) that withstands, final stage gear (5) interlock of gear (12) under the effect of gravity and in the gear train, final stage gear (5) driven gear (12) motion, at this moment and gear (12) be connected same axle and go up eccentric wheel (13) and also and then rotate (as shown in Figure 4) together.Flow value (the 2 tons of water) current that do not reach setting when the disposable water flow of protecting valve by leaking continuously stop by the protection valve that leaks; at this moment be connected on float (7) on piston (8) bar and drive piston (8) rise to the top again and upwards seal water outlet under buoyancy function, piston (8) is pushed lever (11) open makes the gear (12) that is installed in lever (11) one ends separate with final stage gear (5) in the train of reduction gears.Eccentric wheel (13) is partial to an end again under the effect of gravity, flow measurement is made zero and waited for that again current are by the protection valve (as shown in Figure 3) that leaks next time.
If the disposable 2 tons of water (middle without any pause) that reach continuously setting by the water yield of the protection valve that leaks; gear (12) and eccentric wheel (13) produce enough rotations under the drive of final stage gear (5); eccentric wheel (13) is stirred screens bar (10) one ends and is broken away from briquetting (9); briquetting (9) promotes piston (8) and descends under action of gravity, be connected on the water outlet of blocking float (7) lower end on the piston (8) and make current not be in closed condition (as shown in Figure 5) by the protection valve that at this moment leaks.
