Description

High pressure pipe line port sealing structure
Technical field
The utility model relates to a kind of high pressure pipe line port sealing structure.
Background technique
Flange is that Bonding pressure pipeline must use component, is convenient to dismounting and maintenance.Sealing between flange is the important step of whole pressure system leakproof.Different pressure ranges, can select multi-form Sealing.
O RunddichtringO has unique superiority.Under identical positive pressure state, maximum pressure can be produced.That is, just can reach the effect of sealing by less positive pressure, especially make, on the pipeline of horizontal positioned, not easily to drop.This brings great convenience when installation, dismounting, maintenance to installation and maintenance personnel.But O RunddichtringO is not suitable for the situation of high pressure, is easily out of shape when pressure is larger, there is the possibility being extruded space.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, uses O RunddichtringO and sealing effect good high pressure pipe line port sealing structure under providing one to be applicable to hyperbaric environment.
The purpose of this utility model is achieved in that
A kind of high pressure pipe line port sealing structure, it comprises body, the mouth of pipe of body is provided with fastening flange, the arranged outside of fastening flange has mounting flange, fastening flange and the outer ring of mounting flange are provided with the corresponding bolt hole arranged of a circle, bolt is provided with in bolt hole, bolt revolves and puts nut, the arranged outside of fastening flange has a circle arc-shaped ring groove, the inner side of mounting flange is provided with a circle rectangle annular groove, arc-shaped ring groove is corresponding with the position of rectangle annular groove, arc-shaped ring groove and rectangle annular groove are arranged at the inner ring of bolt hole, an O type circle is had to be embedded in arc-shaped ring groove and rectangle annular groove, the segmentum laterale of O type circle is embedded in rectangle annular groove, the medial segment of O type circle is embedded in arc-shaped ring groove, be fixed flange and mounting flange of the stage casing of O type circle is squeezed between fastening flange and mounting flange.
Preferred as one, the degree of depth of arc-shaped ring groove is less than the radius of O type circle, and the groove width of rectangle annular groove is greater than O type circle width 1mm, and the groove depth of rectangle annular groove is 1.5mm, and the sharp edge of arc-shaped ring groove and rectangle annular groove is provided with the chamfering of R0.3mm.
Compared with prior art, the beneficial effects of the utility model are:
Under the utility model high pressure pipe line port sealing structure uses O RunddichtringO to be applicable to hyperbaric environment, and sealing effect is better.

Embodiment
See Fig. 1 ~ Fig. 4, a kind of high pressure pipe line port sealing structure that the utility model relates to, it comprises body 1, the mouth of pipe of body 1 is provided with fastening flange 2, the arranged outside of fastening flange 2 has mounting flange 3, fastening flange 2 and the outer ring of mounting flange 3 are provided with the corresponding bolt hole arranged of a circle, bolt 4 is provided with in bolt hole, the arranged outside of fastening flange 2 has a circle arc-shaped ring groove, the inner side of mounting flange 3 is provided with a circle rectangle annular groove, arc-shaped ring groove is corresponding with the position of rectangle annular groove, arc-shaped ring groove and rectangle annular groove are arranged at the inner ring of bolt hole, O type circle 5 is placed in arc-shaped ring groove, the diameter of O type circle 5 is 7 ~ 8mm, O type circle some be positioned at arc-shaped ring groove, O type circle some be positioned at rectangle annular groove, the degree of depth of arc-shaped ring groove is less than the radius of O type circle 5, the groove width of rectangle annular groove is greater than O type circle width 1mm, the groove depth of rectangle annular groove is 1.5mm, the sharp edge of arc-shaped ring groove and rectangle annular groove is provided with the chamfering of R0.3mm.
Assembly Instruction Device:
As shown in Figure 1, O type circle is placed in the arc-shaped ring groove of fastening flange, then mounting flange lid is placed in the outside of fastening flange, make the position of bolt hole corresponding, then in bolt hole, bolt is screwed into, nut is screwed into again on bolt, see Fig. 2, fastening nut, fastening flange and mounting flange are locked, now O type circle generation deformation, the segmentum laterale of O type circle is embedded in rectangle annular groove, the medial segment of O type circle is embedded in arc-shaped ring groove, be fixed flange and mounting flange of the stage casing of O type circle is squeezed between fastening flange and mounting flange, now, gap is left between fastening flange and mounting flange, only seal at O type circle place.
