Most preferred embodiment of the present utility model is such, referring to figs. 1 through Fig. 8, main body (25) is like tee union, but have barrier platform (28), barrier platform (28) water port (29) to be arranged in the middle of inner chamber is divided into water-inlet cavity (30), water chamber (31), barrier platform (28) in the inner chamber, communicating between water-inlet cavity (30) and the water chamber (31) is communicated with by hole (29).The valve pocket (32) that floats communicates with turnover water cavity (30,31).There is 0.4 aperture at floating valve (16) center, communicates with water-inlet cavity (30) when the hydraulic pressure of pressure chamber equates with water inlet pressure.There are chamber (36,37,38), inner chamber (36) to communicate with secondary water in the floating valve (16) by hole (35), it is uniform that hole (35) is illustrated in figure 6 as 4-φ 6, the screw thread (34) on floating valve (16) top is inserted in flat cushion rubber (23) earlier, plain washer (24) overlaps hand-hole (29) again after shoulder (39) is gone up, use nut (26) to reinforce at last, cushion rubber (23) is close to the barrier platform (28) in hole (29), circle (24) external diameter manufactures mutually with aperture, hole (29), and sealing separates water-inlet cavity (30) and water chamber (31) water-tight can be inserted in promptly.Cushion rubber (23), packing ring (24) break away from and portal (29), and (29) flow to hole (31) and go out the water of water-inlet cavity (30) from the hole.Floating valve (16) outside diameter wall is also fluted to be used to install D30Y shape circle (18), floating valve (16) external diameter also is inserted in the internal diameter of chamber (32), filter screen (22) has been inserted in counterbore (40) lining on floating valve (16) inner chamber (36) top, the face end of filter screen gland (17) by spring (41) roof pressure, floating valve (16), spring (27), partly be contained in lining, chamber (32) by the big end pressure head of core (14), having on the outer ring boss of main body (25) sluices rushes down and presses hole (34), aperture φ 2.8 through holes to communicate with water chamber (31).Be inserted in overcoat (15) on the external diameter boss of chamber (32), sealed by O shape circle (4) between it.Be inserted in the external diameter of transferring core (14) in overcoat (15) the small end endoporus.Go into crown cap by core (11) front end encapsulation and be used to promote spring (27), pack into by core (11) and transfer in core (14) endoporus, by having groove to be used to install V-type small sealing ring (13) on core (11) external diameter, seal ring (13) external diameter is close to sealing with transferring core (14) endoporus.By core (11) tail end joint (8) is housed, tightens up with heavy screw (10).Head (8) has counterbore, is inserted in and transfers core (14) external diameter port, can be up and down.Spring (12) is housed therebetween, and spring (12) endoporus is inserted in by core (11) external diameter.Head (8) also is equipped with spring (12) to transferring between the core (14).

Implementation and operation of the present utility model is such, and chamber (31) are valve opening and closing passage throat, and the sealing platform the when plane that water chamber (31) contacts with flat cushion rubber (23) is valve closing is the position of separating pool and exhalant region.When valve is in closed condition, be closed in chamber (30) from the water of coming in.Floating valve (16), main body (25) inner chamber, transfer core (14), the compression chamber (31) formed by core (11), cushion rubber (6), O type circle (5), Y-shaped ring (18) and incompressible chamber (30) its all can be referred to as pressure chamber, be communicated with water intake (41) by the aperture (33) in the floating valve (16), and the hydraulic pressure in the pressure chamber is equated with the outer pressure of water intake (41) by force, lifting surface area because of pressure chamber is bigger than inhalant region area again, can seal fully so can guarantee sealing rubber pad (23).

Application principle of the present utility model is such.During use, promote head (8), drive the sealing surface that L shaped cushion rubber (6) breaks away from and transfer core (14), beginning pressure release in the pressure chamber thereby make by core (11).Head (8) continues to press, and goes after the idle running, and the water pressurized in compressible chamber (31) is discharged.By the interstitial row between main body (25) and the overcoat (15) to the water outlet oral region.Decontrol head (8), spring (12) promotes press core (11), L shaped cushion rubber (6) and transfers core (14) sealing, the interior water of pressure chamber to and main body (25) and overcoat (15) between water outlet direction leakage path disconnected.Because the water in the original compressible chamber (31) has been forced out mouth, therefore, pressure in the pressure chamber is less than the pressure of water intake (41), floating valve (16) is located to be compressed direction to compressible chamber (31) under the pressure effect of water and is moved at water intake (41), seal flat rubber cushion (23) and leave the plane that water intake (41) is connected with water chamber water outlet (31), water intake (41) is connected with water chamber water outlet (31), and valve is in opening state.At this moment, some water is by filter screen (22), and enters compressible chamber (31) and incompressible chamber (30) from gland (17) central small hole (33), and the spool that promotes valve (16) owing to the effect of water pressure difference moves to chamber (31) water outlet direction.Cut off chamber (31) water outlet water outlet until the flat rubber cushion of sealing (23), valve has been realized time-delay automatic on-off function in this process.
