The specific embodiment
The utility model be connected with the tap water water inlet pipe of water tank bottom and be fixed in the water tank case at the bottom of on the upper end of following valve body 1 of tubulose, being connected with its bottom has on projection water inlet tube head 501 and its and has the upper valve body 5 that weep hole 502 bottoms are the expanding reach tubulose, be equipped with a guide rod that can move up and down 7 in the inner chamber of upper valve body 5, the floating drum 6 that is loaded with water in one is fixed on the top of guide rod 7, the lower end of guide rod 7 be connected with can shutoff projection water inlet tube head 501 water inlets of upper valve body have the spool 8 of closing function, this spool 8 is that its upper end is connected with guide rod 7 by the external screw thread that has, its lower end is inlaid with the core bar of rubber seal 801, be equipped with the rubber non-return cover 9 that its bottom has the inlet opening in the following bottom of valve body 1 inner chamber, be placed with check ball 10 in the non-return cover 9.
Middle part at following valve body 1 has annular boss 101, the below of annular boss 101 is equipped with sealing mat 3, its hypomere has external screw thread, be equipped with hold-down nut 2 on it, top have with upper valve body 1 expanding reach on the interconnective internal thread of external screw thread, be equipped with sealing mat 4 between the annular boss 503 that on down valve body 1 and upper valve body 5, has.
Said floating drum 6, a cylindrical shell of pegging graft and forming by first cylindrical shell 602 and second cylindrical shell 603 of the central authorities at the tube intonation have respectively with it is vertical that cylindrical shell is combined as a whole bar cover 604,605, and be equipped with the bonding adhesive of sealing and fixing at splicing position, be equipped with water injection hole 601 on first cylindrical shell 602, the bar cover 604 of first cylindrical shell and the bar cover 605 of second cylindrical shell are docked, and stick with glue the agent fixing seal, in guide rod 5 insertion rods cover 604,605, floating drum 6 is stuck on the guide rod 5 securely.
Bar that the central authorities in second 603 chambeies of cylindrical shell have cover 605 is that the tube bear building-up with second cylindrical shell 603 is integrated, and upper valve body 5 places the below at the bottom of 603 of second cylindrical shells.
Bar that the central authorities in second 603 chambeies of cylindrical shell have cover 605 is that the cylindric groove that the tube with second cylindrical shell 603 is equipped with at the end is combined as a whole, and upper valve body 5 places groove.
