[0007] Preferably, the inner wall of the inner sleeve column is fixedly connected with the outer wall of the push rod.

[0008] Preferably, the outer wall of the push rod is embedded with two groups of sealing ring one, and the outer wall of the two groups of sealing ring one is in abutment with the inner wall of the inner sleeve column.

[0009] Preferably, the outer wall of the seal seat is fixedly connected with a protective sleeve, the cross section of the protective sleeve is in the form of a tapered structure, and the inner wall of the protective sleeve is in sliding connection with the outer wall of the inner sleeve column.

[0010] Preferably, the push assembly comprises a T-shaped swing seat, the top of the float ball member is fixedly connected with a ball arm combined with the bottom of the vertical end of the swing seat, the horizontal end of the swing seat is hingedly connected with the inner wall of the shell, the horizontal end of the swing seat is hingedly connected with a swing arm, and the open end of the swing arm is hingedly connected with the push rod.

[0011] Preferably, the outer shell top inner wall is fixedly connected with a limiting seat, and an inclined surface matched with the swing seat is arranged on the limiting seat.

[0012] In conclusion, the beneficial effects of the present application are as follows:

[0013] 1. In the present application, as the water level in the water tank rises, the floating ball member drives the swing seat to deflect, the swing seat drives the push rod through linkage of the swing arm, the push rod drives the sealing seat to combine with the inlet, and so on, so as to realize automatic opening and closing of the valve, the sealing ring two at the inlet ensures the sealing property of the combination of the sealing seat and the inlet, the T-shaped structure formed by the push rod and the sealing seat makes the pushing force larger, and the sealing ring on the outer side of the push rod can prevent impurities from entering the gap between the inner sleeve column and the push rod when the water in the upper fish tank flows down.

The outer wall of the push rod 7 is embedded with two groups of sealing rings I 11, and the outer wall of the two groups of sealing rings I 11 is in abutment with the inner wall of the inner sleeve column 10, so as to ensure the water tightness between them. The outer wall of the sealing seat 13 is fixedly connected with a protective sleeve 12, the cross section of the protective sleeve 12 is in a conical structure, the inner wall of the protective sleeve 12 is slidably connected with the outer wall of the inner sleeve column 10, and the protective sleeve 12 on the outer side of the sealing seat 13 is slidably matched with the outer wall of the inner sleeve column 10 with the push-pull of the push rod 7 and the sealing seat 13. The conical cross section of the protective sleeve 12 can uniformly bear the stress of the sealing seat 13 on one hand, and further isolate the impurities in the water on the other hand, so as to avoid the impurities from being combined to the connection between the push rod 7 and the inner sleeve column 10, thereby further ensuring the stability of the use of the floating ball valve with the sealing structure.

[0027] Specifically, as shown in the drawings, Figure 2 and Figure 3 As shown, the push assembly includes a T-shaped swing seat 5, the top of the floating ball member 8 is fixedly connected with a ball arm combined with the bottom of the vertical end of the swing seat 5, one side of the horizontal end of the swing seat 5 is hinged with the inner wall of the outer shell 4, the other side of the horizontal end of the swing seat 5 is hinged with a swing arm 6, and the open end of the swing arm 6 is hinged with the push rod 7. With the rising of the water level in the water tank, the floating ball member 8 drives the swing seat 5 to deflect, the swing seat 5 drives the push rod 7 through the swing arm 6, and the push rod 7 drives the sealing seat 13 to combine with the inlet 2.
