Abstract
The utility model discloses an improved generation pole sealing device of wafer valve, this improved generation pole sealing device include gland (1), lip type pack (2), copper backing (3) and " O " type circle (5), and clearance two lip type of installation with valve gap (4) pack (2) at valve rod (6), and two lip type pack (2) upper and lower and set up one copper backing (3) respectively to it is sealed by gland (1), interior peripheral hardware " O " the type circle (5) of copper backing (3). The utility model discloses pack with forming by gland compression lip type and seal, if not hard up " O " type circle of gland also can be guaranteed to seal, improve the sealing performance of wafer valve, improve the security of wafer valve.
Description
Technical field
This utility model relates to flap type, is specifically related to the modified model rod seal apparatus of flap type.
Background technology
At present, the rod seal of the flap type that domestic market uses is all lip type packing seal, and this type of seals valve rod and fills out
The surface roughness requirements of magazine is the highest, and is extremely difficult to the requirement of hermetic seal.
Summary of the invention
The purpose of this utility model is: provides the modified model rod seal apparatus of a kind of flap type, improves the close of flap type
Sealing property, improves the safety of flap type.
Technical solution of the present utility model is: this modified model rod seal apparatus includes gland, lip type filler, copper
Pad and "O"-ring, install two lip type fillers in the gap of valve rod and valve gap, two lip type fillers be respectively provided with one up and down
Individual copper backing, and sealed by gland, the interior peripheral hardware "O"-ring of copper backing.
The utility model has the advantages that:
A, this rod seal apparatus include two lip type fillers, two copper backings and "O"-ring and gland, by filler pressure
Lid compression lip type filler is formed and seals, if gland loosens "O"-ring it is also ensured that seal.
When B, emergency maintenance, if lip type filler can not be purchased timely, depend "O"-ring alone and valve can also be made stably to transport
OK.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 gland, 2 lip type fillers, 3 copper backings, 4 valve gaps, 5 "O"-rings, 6 valve rods.
Detailed description of the invention
As it is shown in figure 1, this modified model rod seal apparatus includes gland 1, lip type filler 2, copper backing 3 and "O"-ring
5, in the gap of valve rod 6 with valve gap 4, two lip type fillers 2 are installed, two lip type fillers 2 be respectively provided with a copper backing up and down
3, and sealed by gland 1, the interior peripheral hardware "O"-ring 5 of copper backing 3.
