And sidepiece arranges two O-ring seals, for the sealing between valve seat and valve body, valve seat stepped sides are pasted with sealing ring one
Tightly, in case medium is revealed, bottom is domatic structure, and the side contacted with medium in domatic structure is highly more than and valve body contact
Side, for increasing the contact area of valve seat and medium so that valve seat under the promotion of medium to the side compression of dish plate one, under valve seat
Surface is adjacent to sealing ring two, and the sealing ring two is arranged at side corresponding with valve seat on dish plate, between dish plate and valve seat
Sealing, in case medium is revealed, and is provided with pad between sealing ring two and dish plate, the pressing plate is arranged at dish plate top front end,
For compress gasket and sealing ring two；
Accordingly, the slope aspect of valve seat lower surface is identical with sealing ring two and dish plate upper surface slope aspect；
When driving means band ovable valve stem drives dish plate to close, spring offsets with the support ring of valve seat front end, and buffering compresses spiral shell
Frictional force between female and dish plate, and ground floor sealing is formed by sealing ring one and O-ring；Medium is being flowed to the process of B by A
It is middle to form certain thrust, oppress dish plate and extrude to the direction of B, the work of rightabout power is formed between dish plate and sealing ring two
With, second layer sealing is formed, effectively prevent medium from revealing.
