It is good, it is to avoid rust water or corrosion phenomenon occur.
According to the technical scheme that this utility model is provided, soft sealing gate valve includes valve gap, valve body, valve rod, valve disc and valve plate,
It is characterized in that：Valve disc is provided with valve body, and valve disc upper end supports connection valve rod, valve rod lower end inside affixed bushing to lead on the inside of bushing
Threaded connection valve plate is crossed, in the valve opening that valve body lower end is stretched into through valve disc in valve plate lower end, valve opening inside lower end face is smooth surface；
The valve plate Surface coating caulking gum layer；Valve body upper end is bolted valve gap, is provided with valve rod and leads between valve gap and valve rod
To block, valve gap is stretched out in the upper end of valve rod.
Further, caulking gum layer is made using food stage elastomeric material.
Further, multiple first O-ring seals are provided between stem guiding block and valve rod.
Further, the second O-ring seal is provided between stem guiding block and valve disc.
Further, the 3rd O-ring seal is provided between valve disc and valve body.
Further, dirt-proof boot is provided between valve gap and valve rod.
Further, valve disc and stem guiding block are made using food grade plastic materials.
Compared with the prior art this utility model has advantages below：
This utility model simple structure, compact, reasonable, valve opening inside lower end face is smooth surface, and smooth surface causes stream
