The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1 and Figure 2, the draining valve that a kind of toilet cistern is used comprises base 1, spool 2A, and the upper end of described base 1 has valve core case 11, lower end to have water outlet to take over 12, the air inlet pipe 13 and base 1 intracavity inter-connection of sidepiece;

Also comprise valve body 2, valve gap 3, half water key 41, full water key 42, transmission mechanism 8, go up float 51 and following float 52;

Described valve body 2 has intake antrum 21, control chamber 22, and radially water inlet 26 is arranged on intake antrum 22 walls, and intake antrum 21 is communicated with by a through hole 23 with control chamber 22, and intake antrum 21 is communicated with base 1 inner chamber; The base plate of control chamber 22 has a guide pipe 221, and guide pipe 221 is communicated with intake antrum 21 with control chamber 22; Following float 52 is arranged in the control chamber 22, is slidingly matched with guide pipe 221; Valve rod 6 upper ends are passed guide pipe 221 and are fixedlyed connected with last float 51, and last float 51 is provided with down on the float 52, and last float 51 is provided with two dihedral arms 511, and dihedral arm 511 is symmetrical arranged along diameter line; Have on the valve body 2 along symmetrically arranged two gathering sills 24 of diameter line, dihedral arm 511 1 ends are fixedlyed connected with last float 51, the other end and gathering sill 24 are slidingly matched; Valve body 2 walls of upper and
