Preferably, being provided with sealing structure between described valve rod and valve body, described sealing structure includes box nut, thrust
Ring, is disposed with the first seal groove, first annular groove and the second annular groove from top to bottom in described upper box nut, and first
Sealing ring is used in combination with described first seal groove, described first annular groove and the second annular groove respectively be arranged on valve
First annular projection and the second annular lug on bar are used in combination, and are provided with thrust ring below described upper box nut, described
Being provided with the second sealing ring between upper box nut and thrust ring, described thrust ring lateral wall is connected with described upper cover inwall, institute
Being provided with the 3rd annular groove and fourth annular groove in stating thrust ring, described 3rd annular groove is with fourth annular groove respectively
It is used in combination with the 3rd annular lug being arranged on valve rod and fourth annular projection, below described thrust ring, is provided with the 3rd
Sealing ring.
Compared with prior art, the beneficial effects of the utility model are: the valve of the present invention, offer valve plate in upper cover
Chamber so that valve plate, when standard-sized sheet, is not exposed to upper cover, and the hangers of valve plate is unsettled, not by external impacts, it is to avoid hangers is impaired,
The harmful effects such as coating is impaired, corrosion, safer, environmental protection., it is simple to promotion and application.

Part is connected with another parts.
Embodiment 1
As shown in Figure 1-Figure 3, this utility model be the technical scheme is that a kind of valve with valve plate isolation structure
Door, described valve includes valve rod, upper cover and valve plate, valve body, is provided with isolation room, the height of described isolation room in described upper cover
More than or equal to the height of described valve plate, when valve opening when, described valve plate can all be raised in isolation room.
Preferably, being provided with sealing structure between described valve rod and valve body, described sealing structure includes box nut, thrust
Ring, is disposed with the first seal groove, first annular groove and the second annular groove from top to bottom in described upper box nut, described
First sealing ring is used in combination with described first seal groove, described first annular groove and the second annular groove respectively with setting
First annular projection and the second annular lug on valve rod are used in combination, and are provided with thrust ring below described upper box nut,
Being provided with the second sealing ring between described upper box nut and thrust ring, described thrust ring lateral wall is connected with described upper cover inwall
Connecing, be provided with the 3rd annular groove and fourth annular groove in described thrust ring, described 3rd annular groove is recessed with fourth annular
Groove is used in combination with the 3rd annular lug being arranged on valve rod and fourth annular projection respectively, arranges below described thrust ring
There is the 3rd sealing ring.
Compared with prior art, the beneficial effects of the utility model are: the valve of the present invention, offer valve plate in upper cover
Chamber so that valve plate, when standard-sized sheet, is not exposed to upper cover, and the hangers of valve plate is unsettled, not by external impacts, it is to avoid hangers is impaired,
