The specific embodiment

At Fig. 1, among Fig. 2, time-delay valve, comprise and bringing into, the valve body 1 of delivery port, have in the valve body 1 at interval, the time-delay chamber 5 of the waterline 2 of water outlet and control discharge time, the centre of waterline 2 has through hole 10, in time-delay chamber 5, buoyancy aid 3 is installed by through hole 10, the top of buoyancy aid 3 is equipped with spool 4, on the buoyancy aid 3, and the sealing ring 6 of trough of belt 11 is installed between the inwall in time-delay chamber 5, and sealing ring 6 is mounted in the seal groove 3 ' of buoyancy aid 3, and buoyancy aid 3 movable sets are in through hole 10, for anti-sealing seepage from through hole 10, the utility model is equipped with flat RunddichtringO 12 on buoyancy aid 3 tops; In the buoyancy aid 3, spool 4 belows are equipped with the compression spring 9 that resets.

Press bottom spool 4, be movably arranged on the water of buoyancy aid 3 in lower compression time-delay chamber 5 in the time-delay chamber 5, the slit appears in the end face of the spool 4 in the buoyancy aid 3 and the contact surface of planar seal ring 13 simultaneously, water in the time-delay chamber 5 flows out from this slit like this, because advance this moment, intake pressure outside the delivery port interval waterline 2 is bigger than the pressure of water in the time-delay chamber 5, buoyancy aid 3 integral body will move down, the upper end of buoyancy aid 3 just breaks away from the through hole 10 on the waterline 2, water comes out to delivery port from through hole 10, because the water in the time-delay chamber 5 has flowed out a part, water from water inlet is by the water filling in time-delay chamber 5 of the groove 11 on the sealing ring 6, water in time-delay chamber 5 reaches certain water level, water with buoyancy aid 3 upwards jack-up up to buoyancy aid 3 through hole on the waterline 2 10 is closed, advance, delivery port is spaced apart by waterline 2, thereby delivery port stops water outlet, realizes the effect that time-delay control discharges water.
