Abstract
A kind of valve rod double sealing structure, including stuffing nut, filler stud, spring pocket, disc spring, hold-down grid, filler pressing sleeve, filler I, washer I, fixed ring, filler II, washer II, valve deck, valve rod, it is characterized in that the fixed ring is threadedly coupled with valve deck, it squeezes filler II to seal together with stem member formation, the filler pressing sleeve, hold-down grid squeeze filler I and stem member forms another road and seals.The advantage of the invention is that filler and valve rod form dual-seal, sealing performance is improved.
Description
Technical field
The present invention relates to a kind of double sealing structures of Heisui River angle valve valve rod.
Background technique
With the development of coal chemical industry, Heisui River angle valve is mainly used in gasification process, is mounted on gasification outlet of still, washing
The positions such as tower, flash tank entrance control the pressurization and pressure release of gasification furnace unit feed and discharging, and Heisui River angle valve seals at present
Performance is poor, leads to dielectric leakage phenomenon.
Summary of the invention
The purpose of the present invention is to provide a kind of solution Heisui River angle valves poor sealing performance occurs, leads to the valve rod of dielectric leakage
Double sealing structure.
The technical solution adopted by the present invention to solve the technical problems is a kind of valve rod double sealing structure, including filler
Nut, filler stud, spring pocket, disc spring, hold-down grid, filler pressing sleeve, filler I, washer I, fixed ring, filler II, washer II,
Valve deck, valve rod, the fixed ring are threadedly coupled with valve deck, are squeezed filler II and are sealed together with stem member formation, the filler
Pressing sleeve, hold-down grid squeeze filler I and stem member forms another road and seals.
The filler I is braided packing.
The filler II is V-type filler.
The present invention compared with the existing technology, the advantage is that the two seals formed by filler and stem member, substantially
Improve sealing performance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment.
In figure: 1, stuffing nut；2, filler stud；3, spring pocket；4, disc spring；5, hold-down grid；6, filler pressing sleeve；7, it fills out
Expect I；8, washer I；9, fixed ring；10, filler II；11, washer II；12, valve deck；13, valve rod.
Specific embodiment
As shown in Figure 1, a kind of valve rod double sealing structure, including stuffing nut, filler stud, spring pocket, disc spring, filler
Pressing plate, filler pressing sleeve, filler I, washer I, fixed ring, filler II, washer II, valve deck, valve rod, the fixed ring and valve deck screw thread
Connection squeezes filler II and seals together with stem member formation, and the filler pressing sleeve, hold-down grid squeeze filler I and valve stem
Part forms another road sealing, and the filler I is braided packing, and the filler II is V-type filler.
