Description
Technical field
The utility model relates generally to a kind of for the preventing water leakage protective device on the tap water supply pipeline.
Background technology
Residential building is cut off the water, and often having gos out forgets the resident family of closed tap or valve, in case come water, owing to can not in time close water pipe, causes flowing water, not only wastes resource, and causes any property loss for oneself and other people.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, in case cut off the water the preventing water leakage protective device that can automatically water pipe be sealed.
The technical solution adopted in the utility model is: the preventing water leakage protective device, consist of a body by upper connecting tube, middle adapter and lower linking tube, and be provided with ball float in the body, in middle adapter, be provided with guiding device, be provided with discharging valve in middle adapter.
Above-mentioned preventing water leakage protective device, described guiding device is: the guide cylinder outer rim connects some junction plates, on the guide cylinder outer wall between per two junction plates, the baffle plate I is flexibly connected by axle I and guide cylinder outer wall, and the baffle plate II is flexibly connected by axle II and guide cylinder outer wall; The baffle plate III is flexibly connected by axle III and baffle plate II; The baffle plate IV is connected with the upper end of guide cylinder by the axle IV.Like this, by the rising passway I that forms ball float in the guide cylinder, formed the decline passway II of ball float by guide cylinder outer wall, junction plate and middle nozzle inner wall.
Above-mentioned preventing water leakage protective device, described baffle plate IV is triangle or arc.
Above-mentioned preventing water leakage protective device, middle nozzle inner wall is provided with holddown groove, and guiding device inserts in the holddown groove by junction plate and fixes with middle adapter.
The beneficial effects of the utility model are: the utility model is installed on the water supply pipeline of resident family; during normal water; ball float is between baffle plate I and the baffle plate II; in case cut off the water; cutout cock is forgotten by resident family; there is not hydraulic pressure on the water supply pipeline; water in the preventing water leakage protective device flows into trunk line naturally, and baffle plate I and baffle plate II fall under the effect of deadweight, and ball float falls thereupon the mouth of pipe of lower linking tube is blocked; in case come water; water enters the preventing water leakage protective device under pressure, the baffle plate I; baffle plate II and baffle plate III are launched under the effect of hydraulic pressure; the passage II is blocked; ball float can only rise along the passage I in the guide cylinder, and the baffle plate IV is washed open, continues to rise the mouth of pipe of upper connecting tube is blocked; even so unexpected water can not flow out from tap yet.After resident family goes home, only need open discharging valve, under hydraulic pressure, the baffle plate IV is blocked the passage I from falling, and the baffle plate I is opened the passage II from falling, and ball float descends with water level and falls between baffle plate I and the baffle plate II, thereby does not affect normal water.

The specific embodiment
As shown in Figure 1, the preventing water leakage protective device consists of a body by upper connecting tube (1), middle adapter (2) and lower linking tube (3), is provided with ball float (4) in the body, is provided with guiding device in middle adapter (2), is provided with discharging valve (5) in middle adapter (2).
As shown in Figures 2 and 3, guiding device is: guide cylinder (6) outer rim connects some junction plates (7), on guide cylinder (6) outer wall between per two junction plates (7), baffle plate I (8) is flexibly connected by axle I (9) and guide cylinder (6) outer wall, and baffle plate II (10) is flexibly connected by axle II (11) and guide cylinder (6) outer wall; Baffle plate III (12) is flexibly connected by axle III (13) and baffle plate II (10); Baffle plate IV (14) is connected with the upper end of guide cylinder (6) by axle IV (15).Like this, by the rising passway I (17) that forms ball float in the guide cylinder, formed the decline passway II (18) of ball float by guide cylinder outer wall, junction plate and middle nozzle inner wall.
Fall for the ease of ball float, baffle plate IV (14) can be made triangle or arc.
Fix for the ease of guiding device and middle adapter, be provided with holddown groove (16) at middle adapter (2) inwall, it is interior and fixing with middle adapter (2) that guiding device inserts holddown groove (16) by junction plate (7).
The course of work of the present utility model is: the utility model is installed on the water supply pipeline of resident family.As shown in Figure 2, during normal water, ball float is between baffle plate I and the baffle plate II, because the length of baffle plate I and baffle plate II is greater than the ultimate range between middle nozzle inner wall and the guide cylinder outer wall in the passage II, therefore baffle plate I and baffle plate II are in the passage II, even also can only be downward-sloping under the effect of hydraulic pressure, so ball float can not rise along the passage II, the mouth of pipe of assurance upper connecting tube and the mouth of pipe of lower linking tube are unimpeded, the normal water of resident family.As shown in Figure 4; when cutting off the water; when cutout cock is forgotten by resident family; do not have hydraulic pressure on the water supply pipeline, the water in the preventing water leakage protective device flows into trunk line naturally and emptying, and the baffle plate IV resets under the effect of deadweight; the passage I is closed; baffle plate I and baffle plate II fall under the effect of deadweight, and the passage II is opened, and ball float falls thereupon the mouth of pipe of lower linking tube is blocked.As shown in Figure 5, suddenly during water, water enters the guiding device device under pressure, baffle plate I, baffle plate II and baffle plate III are launched under the effect of hydraulic pressure, the passage II is closed, ball float can only rise along the passage I in the guide cylinder, and the baffle plate IV is washed open, continues to rise the mouth of pipe of upper connecting tube is blocked, even so unexpected water, water can not flow out from tap yet.After resident family goes home, only need open discharging valve, under hydraulic pressure, the baffle plate IV is blocked the passage I from falling, and the baffle plate I is opened the passage II from falling, and ball float descends with water level and falls between baffle plate I and the baffle plate II, thereby does not affect normal water.
