Description
Technical field
The utility model relates to valve technology field more particularly to a kind of packing seal structures.
Background technique
As shown in Figure 1, existing packing seal structure is mainly by filler (serial number 1), filler pressing sleeve (serial number 2), filler pressure
(serial number 3) and filler bolt (serial number 4) composition are covered, which has the disadvantage in that 1, filler compresses filler by filler pressing sleeve
Reach sealing, due to needing upper hold-down grid, stand steel pipe diameter will be very big, also needs to open a window to tighten bolt holder
Mouthful；2, it since bracket has opened window, will cause ponding, cannot achieve the effect that waterproof；3, filler is compressed with filler pressing sleeve, when filling out
It when grinding abrasion, cannot compensate automatically, need to reach compression filler with the tight bolt of spanner；4, the Reliability of Packing Seal is not as good as O-shaped
Sealing ring.
Utility model content
The utility model is intended to provide packing seal structure, and sealing performance is reliable, has automatic compensation function.
In order to achieve the above objectives, the technical solution adopted in the utility model is as follows:
A kind of packing seal structure seals by O-ring and adds above filler disc spring, can be certainly when filler is worn
Dynamic compensation, while can have certain water-proof function to avoid filler pressing sleeve, gland and people's filler bolt etc. is used.It includes
Filler assembly and bracket for compressing filler, filler assembly includes lower filler, upper filler, spacer ring, the first retaining ring, the second retaining ring
And disc spring, the spacer ring are set between lower filler and upper filler, the first retaining ring is set between spacer ring and lower filler, and the second retaining ring is set
Between spacer ring and upper filler, disc spring is set between bracket and upper filler；The spacer ring inner sidewall and/or lateral wall have for pacifying
The groove of O-ring seal is filled, O-ring seal is installed in the groove.
Wherein, the material of the first retaining ring is metal.
Wherein, the material of the second retaining ring is metal.
Further, the spacer ring inner sidewall is equipped at intervals with two grooves.
Further, the spacer ring lateral wall is equipped at intervals with two grooves.
Compared with prior art, the utility model has the following beneficial effects:
1. the utility model is added to metal collar between filler and spacer ring, all added in spacer ring medial lateral O-shaped close
Seal is sealed by O-ring seal, can greatly reinforce the sealing performance of packing seal structure in this way；
Metal collar is also added above filler on 2., has made filling-material structure that there is certain fire resistance property；
3. having added disc spring above metal collar, disc spring directly compresses filler by bracket, when filler abrasion, disc spring energy
Enough play the function of compensating automatically；
4. disc spring directly compresses filler by bracket, so filled gland, filler pressing sleeve and filler bolt etc. are not needed,
The size of stand steel pipe can change much smaller, therefore also save many materials；Due to not having to tight filler bolt, bracket is just not required to
Windowing is wanted, makes packing seal structure that there is certain waterproof performance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the prior art；
Fig. 2 is the structural schematic diagram of the utility model；
In figure: the first retaining ring of filler 6-, the sealing of 7-O type under 1- filler, 2- filler pressing sleeve, 3- gland, 4- bolt, 5-
Circle, 8- spacer ring, 9- disc spring, 10- bracket, the upper filler of 11-, the second retaining ring of 12-, 13- third retaining ring.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
As shown in Fig. 2, packing seal structure disclosed by the utility model, the branch including filler assembly and for compressing filler
Frame 10, filler assembly include lower filler 5, upper filler 11, spacer ring 8, the first retaining ring 6, the second retaining ring 12, third retaining ring 13 and disc spring
9, spacer ring 8 is set between lower filler 5 and upper filler 11, and the first retaining ring 6 is set between spacer ring 8 and lower filler 5, and the second retaining ring 12 is set
Between spacer ring 8 and upper filler 11, third retaining ring 13 is set to upper 11 top of filler, and disc spring 9 is set to bracket 10 and third retaining ring 13
Between.Wherein, the material of the first retaining ring 6, the second retaining ring 12 and third retaining ring 13 is metal.
8 inner sidewall of spacer ring and lateral wall have the groove for mounting O-shaped sealing ring 7, are equipped with O-ring seal 7 in groove.
8 inner sidewall of spacer ring is equipped at intervals with two grooves, and 8 lateral wall of spacer ring is equipped at intervals with two grooves.
The utility model is added to metal collar between filler and spacer ring, all adds O-shaped sealing in spacer ring medial lateral
Circle, is sealed by O-ring seal, can greatly reinforce the sealing performance of packing seal structure in this way.Metal is also added above filler
Retaining ring makes filling-material structure have certain fire resistance property.Disc spring is added above metal collar, disc spring is directly compressed by bracket
Filler, when filler abrasion, disc spring can play the function of compensating automatically.Disc spring directly compresses filler by bracket, so not
Need filled gland, filler pressing sleeve and filler bolt etc., the size of stand steel pipe can change much smaller, therefore also save not
Few material.Due to not having to tight filler bolt, there is no need to windowings for bracket, and packing seal structure is made to have certain waterproofness
Energy.
The utility model can effectively improve the sealing performance of filler, obtain valve seal reliability and life of product
Greatly promoted.
Certainly, the utility model can also have other numerous embodiments, without departing substantially from the spirit of the present invention and its essence
In the case where, those skilled in the art can make various corresponding changes and modifications, but these according to the utility model
Corresponding changes and modifications all should belong to the protection scope of the utility model the attached claims.
