Background technique
Gate valve is an opening and closing element flashboard, and the direction of motion and flow direction of flashboard are perpendicular, gate valve can only make standard-sized sheet and
Quan Guan cannot make adjustments and throttle.
Since working media is carbon dioxide, ammonia, melamine, characteristic carbon dioxide and ammonia gas mixture are 120
It is easily crystallized at DEG C, melamine easily crystallizes at 320 DEG C, and gaseous mixture is toxic, cannot there is leakage.Therefore ratio is required to valve
It is harsher, it is especially not higher but relatively high to the requirement of the sealing performance of valve to medium temperature control requirement in valve, do not allow
There is leakage.Common gate valve can not control medium temperature in it, cause the medium in valve passage that can crystallize, long-range circumstances
Under, it is easy to make seal failure, valve leak occurs.In view of operating condition particularity, this gate valve heat insulating ability and leakproofness design are very
It is important.
Summary of the invention
The purpose of the present invention is to provide a kind of muff gate valves under special operation condition, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the invention provides the following technical scheme: a kind of muff gate valve under special operation condition,
Including valve body, valve deck is provided with above the valve body, the outer surface of valve body is coated with the first muff, the appearance bread of valve deck
Be covered with the second muff, the top of valve deck is provided with lower filler, and the top of lower filler is provided with filler spacer ring, filler spacer ring it is upper
Side be provided with filler, the first air inlet is provided on second muff, be provided on first muff with it is described
Corresponding first gas outlet of first air inlet.
As a further solution of the present invention: the first inclined hole is provided on the valve deck, first inclined hole is provided with altogether
Six, six the first inclined holes are arranged on valve deck at equal intervals.
As further scheme of the invention: the bottom end of the valve body is provided with the second inclined hole, and second inclined hole is total
It is provided with nine.
As further scheme of the invention: it is provided with conduit between first muff and the second muff, the
One muff is connect with the second muff by the conduit.
As further scheme of the invention: being provided with the second air inlet on the filler spacer ring.
Compared with prior art, the beneficial effects of the present invention are:
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
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1, Fig. 2 and Fig. 3 are please referred to, the present invention provides a kind of technical solution: a kind of muff under special operation condition
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, and the top of lower filler 5 is provided with filler spacer ring
6, the top of filler spacer ring 6 is 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
There are six settings, and six the first inclined holes are arranged at equal intervals on valve deck 3, and when flashboard fully opens, mixing gas medium can be rushed
Brush flashboard crystal, and medium is prevented on flashboard to influence ram seal effect since temperature change flashboard occurs crystallizing again
Fruit, in order to keep the function of valve body 1 more abundant, in the present embodiment, it is preferred that the bottom end of valve body 1 is provided with the second inclined hole, the
Two inclined holes are provided with nine altogether, and nine the second inclined holes are uniformly arranged within the scope of 180 °, when flashboard completely closes, gaseous mixture
