Compared with prior art, the utility model has the beneficial effects that
1. being provided with the first muff and the second muff on gate valve, the second muff is equipped with the first air inlet, mixes
It closes gas medium and is flowed into the second muff from the first air inlet, secondly, the first inclined hole of uniform size is provided on valve deck, to
When flashboard fully opens, mixing gas medium can be by the first inclined hole hushgate plate crystal, in addition, setting on the first muff
There is the first gas outlet, mixing gas medium is flowed out from the first gas outlet, to form a circulation, valve body bottom end is provided with size
Uniform second inclined hole, when flashboard completely closes, mixing gas medium can by the second inclined hole hushgate plate crystal, thus
It prevents since medium can crystallize and make valve invalidation in valve passage.
2. being provided with filler spacer ring on the filler up and down of gate valve, and the second air inlet is provided on filler spacer ring, when
Mixing gas medium can play secondary seal effect when being full of filler spacer ring, to keep the sealing effect of gate valve more preferable.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1, Fig. 2 and Fig. 3 are please referred to, the utility model provides a kind of technical solution: a kind of guarantor under special operation condition
Temperature set gate valve, including valve body 1, the top of valve body 1 are provided with valve deck 3, and the outer surface of valve body 1 is coated with the first muff 2, valve deck
3 outer surface is coated with the second muff 4, and the top of valve deck 3 is provided with lower filler 5, the top of lower filler 5 be provided with filler every
Ring 6, the top of filler spacer ring 6 are provided with filler 7；
Fig. 1, Fig. 2 and Fig. 4 are please referred to, in the present embodiment, it is preferred that the first inclined hole is provided on valve deck 3, the first inclined hole is total
