Example 1

Referring to fig. 1, the present utility model provides the following technical solutions: the utility model provides a self-sealing valve that leakproofness is good, includes self-sealing valve casing 1, fixed plate 4, reset spring 5, first baffle 6, dead lever 8 and fixed block 10, self-sealing valve casing 1 bottom is equipped with inlet port 2, self-sealing valve casing 1 top is equipped with venthole 3, fixed plate 4 lateral part and self-sealing valve casing 1 inner wall rigid coupling, first baffle 6 passes through reset spring 5 and fixed plate 4 top elastic connection, first through-hole 7 has been seted up on the fixed plate 4, dead lever 8 top rigid coupling is in first baffle 6 bottom, first through-hole 7 has been run through to dead lever 8 bottom, dead lever 8 outer wall and first through-hole 7 inner wall sliding contact, second through-hole 9 has been seted up at self-sealing valve casing 1 top, second through-hole 9 and first baffle 6 top rigid coupling have been run through to fixed block 10 bottom, a plurality of air vents 11 have been seted up on the fixed plate 4, the effect that reset baffle 6 was accomplished through reset spring 5, the effect of sealing is accomplished through first baffle 6.

Specifically, the sealing device also comprises a second baffle 12, wherein the top of the second baffle 12 is fixedly connected with the bottom of the fixed rod 8, and the secondary sealing effect is achieved through the second baffle.

Specifically, the sealing device further comprises a first sealing layer 13, the top of the first baffle 6 is provided with the first sealing layer 13, and the sealing performance is improved through the first sealing layer 13.

Specifically, the sealing device further comprises a rubber block 14, the bottoms of the rubber blocks 14 are fixedly connected to the top of the second baffle 12, the rubber block 14 is connected with the air vent 11 in a pile inserting mode, and the sealing performance of the second baffle 12 is improved through the rubber block 14.
