Abstract
The utility model discloses a novel sealing structure for an ultrahigh pressure vessel, which comprises a cylinder body, a sealing plug and a threaded compression ring, wherein the cylinder body is provided with two step holes from the top to the bottom; the lower end of the sealing plug is arranged in the lower step hole; the threaded compression ring is arranged in the upper step hole and connected with the cylinder body through threads; the lower end plane of the threaded compression ring is provided with a compression ring and a sealing ring; the cylinder body is in clearance fit with the sealing plug; grooves is arranged a clearance fit surface; the sealing rings are arranged in the grooves. At the initial working state of the vessel, the rubber O-shaped rings realize initial sealing, which is a movable sealing structure. Meanwhile, the sealing plug moves upwards in the axial direction along with the rising of working pressure, consequently the sealing ring is pressed tightly and the automatic sealing effect is achieved. The sealing form avoids leakages and facilities operation.
Description
Technical field
The utility model relates to the pressurized container field, especially relates to ultrahigh pressure vessel.
Background technique
Ultrahigh pressure vessel is meant design pressure more than or equal to 100MPa (gauge pressure does not contain hydrostatic pressure), and interior media is the equipment that gas, Maximum operating temperature are greater than or equal to the liquid of normal boiling point.Ultrahigh pressure vessel is owing to its operation pressure height, and used plane sealing can not satisfy its usage requirement usually, and the cambridge ring sealing is ultrahigh pressure vessel a kind of self-tightening sealing form commonly used.
Existing sealing configuration as shown in Figure 1, it comprises cylindrical shell 1, sealing plug 2 and threaded pressure ring 3, cylindrical shell 1 is provided with two step holes from top to bottom, the lower end of sealing plug 2 be positioned at by under step hole, threaded pressure ring 3 is positioned at by last step hole.By last step hole inner side mounting thread hole, cylindrical shell 1 is threaded with threaded pressure ring 3, being provided with the hole in the middle of the threaded pressure ring 3 passes for sealing plug 2, the lower end surface of threaded pressure ring 3 is pressed on the step surface of sealing plug 2, be provided with pressure ring 4 between the lower end surface of threaded pressure ring 3 and sealing plug 2 step surfaces, the below of pressure ring 4 also is provided with seal ring 5.On sealing plug 2, also be threaded and carried plug nut 8.
Its working principle is: after assembling, screw and carry plug nut 8, compress the first sealing that seal ring 5 is realized container on the sealing plug 2.During work, internal pressure raises, and sealing plug 2 is axially having the trend that upwards moves freely, thereby compresses seal ring 5, reaches the effect of self-tightening sealing.Interior pressure is high more, and sealing force is big more, seals also reliable more.Its shortcoming is if pretightening force is not enough, reveals when occurring sealing just easily, causes container pressure to raise.
The model utility content
The purpose of this utility model is to provide a kind of sealing effect better ultrahigh pressure vessel sealing configuration.
The technical solution of the utility model is:
The novel sealing structure of ultrahigh pressure vessel, comprise cylindrical shell, sealing plug and threaded pressure ring, cylindrical shell is provided with two step holes from top to bottom, the lower end of sealing plug be positioned at by under step hole, threaded pressure ring is positioned at by last step hole and with cylinder screw and is connected, and the lower end surface of threaded pressure ring is provided with pressure ring and seal ring, is Spielpassung between cylindrical shell and the sealing plug, on this Spielpassung face, be provided with groove, be provided with seal ring in the groove.
Described seal ring is an O type rubber ring.
Described groove is positioned at the bottom of sealing plug, and the quantity of groove and seal ring is greater than one.
The utility model is at the initial stage that container is started working, and rubber o-ring realization sealing is not just leaked, and this is a kind of movable sealing structure.Along with working pressure raises, sealing plug is axially moving up, thereby compresses seal ring, reaches the effect of self-tightening sealing simultaneously.This seal form has been avoided leakage, easy-to-operat.
Description of drawings
Fig. 1 is the schematic representation of original sealing configuration;
Fig. 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 2, the utility model comprises cylindrical shell 1, sealing plug 2 and threaded pressure ring 3, and cylindrical shell 1 is provided with two step holes from top to bottom, the lower end of sealing plug 2 be positioned at by under step hole, threaded pressure ring 3 is positioned at by last step hole.By last step hole inner side mounting thread hole, cylindrical shell 1 is threaded with threaded pressure ring 3, being provided with the hole in the middle of the threaded pressure ring 3 passes for sealing plug 2, the lower end surface of threaded pressure ring 3 is pressed on the step surface of sealing plug 2, be provided with pressure ring 4 between the lower end surface of threaded pressure ring 3 and sealing plug 2 step surfaces, the below of pressure ring 4 also is provided with seal ring 5.
Adopt Spielpassung between cylindrical shell 1 and the sealing plug 2, open channels 6 on sealing plug 2, and O type rubber ring 7 is installed in groove 6, and the specification of groove 6 sizes and rubber ring 7 can be chosen with reference to GB/T 3452.3 standards.Sealing plug 2 is pressed the H7/f8 Spielpassung with seal ring diameter position, and two part conical surface seals, tapering differ from 1 °.Pressure ring 4 does not seal.1 employing buttress thread form of threaded pressure ring 3 and cylindrical shell connects.Groove 6 and rubber ring 7 quantity are two in the present embodiment, also can one or more.
At the initial stage that container is started working, rubber o-ring 7 realization sealings are not just leaked, and this is a kind of movable sealing structure.Along with working pressure raises, sealing plug 2 is axially moving up, thereby compresses seal ring 5, reaches the effect of self-tightening sealing simultaneously.
