Description
It is related to field
The utility model is related to pressure vessel field, more particularly to a kind of new soft seal knot for ultrahigh pressure vessel
Structure.
Background technology
In superhigh-pressure high-temp container, more than 200 DEG C, operating pressure is more than 100MPa to working temperature, is sealed using O-ring
When, it may appear that problems with：First, nitrile rubber, fluorubber temperature in use are unable to reach, and silicon rubber is in making higher than 200 DEG C
Carbonization failure can also occur at a temperature of；2nd, it is too high using special (purpose) rubber sealed price；3rd, this container is renewable bushing appearance
Device is dismantled difficult, it is necessary to often dismounting using metal sealing, and installs and needs very big pretightning force, is not easy to change.
Utility model content
The purpose of this utility model is to overcome shortcoming present in above-mentioned prior art and provide a kind of guarantee at sealing
Sealed reliable, the reliability and durability new soft sealing structure for ultrahigh pressure vessel.
The technical solution of the utility model is as follows：A kind of sealing structure for ultrahigh pressure vessel, the sealing structure bag
Sealing-plug, the first threaded pressure ring, the second threaded pressure ring, cylinder, the first box cupling and the second box cupling are included, under the upper sealing-plug
End is provided with closed groove and open groove, and closed groove is also respectively arranged with first box cupling and the second box cupling
With open groove, the closed groove is by O-ring sealing, and the open groove is sealed by general plug, general to fill in envelope
It is fixed and clamped by baffle plate.
General plug envelope is combined sealing structure, is combined by PTFE3+ springs+PEEK, and the general additional baffle plate of blocking is fixed, gear
Plate uses Q235 steel plates.
The good effect that the technical solution of the utility model is produced is as follows：Sealing structure of the present utility model is by original two
Road O-ring sealing is changed to one O-ring seal form that general plug divides together, and wherein O-ring is sealed and is less than 200 DEG C of works for temperature
Sealing under condition, general plug envelope is for temperature more than the sealing at 200 DEG C reaching the effect of sealing.The utility model is such to be set
Have the benefit that：One is that ensure that seal under HTHP reliability and durability, and two is that sealing position bears high temperature（240℃）And
High pressure（105MPa）, three is to change convenient, low cost.

Specific embodiment
A kind of sealing structure for ultrahigh pressure vessel, as shown in Figure 1,2,3, 4, the sealing structure includes upper sealing-plug
1st, the first threaded pressure ring 2, the second threaded pressure ring 3, cylinder 4, the first box cupling 5 and the second box cupling 6, the lower end of the upper sealing-plug sets
Closed groove 9 and open groove 10 are equipped with, closed groove is also respectively arranged with first box cupling and the second box cupling
With open groove, by O-ring sealing 8, the open groove is by the sealing of general plug envelope 7, general plug for the closed groove
It is combined sealing structure to seal, and is combined by PTFE3+ springs+PEEK, and the open additional baffle plate 11 of groove passes through interior six square-cylindricals
Screw 12 is fixed, and baffle plate uses Q235 steel plates.
O-ring is arranged in the closed groove of upper sealing-plug as shown in Figure 2, closed groove structure is shown in Fig. 3, so
Afterwards by general plug envelope in the open groove of upper sealing-plug as shown in Figure 2, open groove structure is shown in Fig. 3, uses Fig. 4 institutes
The baffle plate for showing and interior six square-cylindricals bolt structure fix general blocking, tighten interior six square-cylindricals screw.Wherein general plug envelope is close for combination
Seal structure, is combined by PTFE3+ springs+PEEK.
Similarly, O-ring and the encapsulation of general plug are fitted over into the first box cupling, second box cupling etc. needs on the part of sealing, afterwards
Load cylinder together with other parts, screw on the second threaded pressure ring, compress the first box cupling, then by the first threaded pressure ring knob the
On two threaded pressure rings, sealing-plug in compression, as shown in Figure 1.
As a example by above sealing-plug and the first box cupling coordinate, mating surface surface smoothness≤0.8 μm, fit tolerance is H8/f7
Gap coordinate, mating surface diameter 170mm, O-ring from 155 × 7 types (《G/T 3452.1-2005》）, it is general plug envelope select 170-
157.8-14（PK19）, Weir Plate Thickness 10, external diameter φ 166, fixing screws six circumference chapiter screw M8x20 in.Operation step
Suddenly：O-ring is put into groove, gash depth 5.5, width 9.5 by one（It is supporting with O-ring）, two by it is general plug envelope be put into it is open
Groove, open gash depth 6.1, width 14（It is supporting with general plug envelope）, three are fixed with baffle plate and tighten interior six square-cylindricals spiral shell
Nail, upper sealing-plug is hung in cylinder and coordinates with cylinder by four, and five compress upper sealing-plug with threaded pressure ring ensures its robust.
