The hexagonal is described to being respectively equipped with groove on silk both sides of head face " to be separately positioned on hexagonal recessed to silk both sides of head for D " type sealing ring
In slot, it is respectively formed and is threadedly coupled with two connecting pipes.
The section of " D " the type sealing ring is " D " shape structure, and being somebody's turn to do " D " shape structure includes " D " type sealing ring medial surface, " D "
Type sealing ring arc surface, the type sealing ring end face " D " and " D " type sealing ring lateral surface, wherein " D " type sealing ring arc surface and " D "
Type sealing ring end face is located at the two sides of " D " type sealing ring.
The groove includes groove medial surface, groove lateral surface and groove end face；The groove medial surface and " D " type seal
Circle medial surface is bonded to form sealing surface, and groove end face is bonded to form sealing surface with " D " type sealing ring end face；Instrumental purpose is in hexagonal
When to silk head, sealing is threadedly coupled silk with connecting pipe formation, while squeezing " D " type sealing ring arc surface, so that " D " type is close
Sealing surface that seal medial surface and groove medial surface are formed and the type sealing ring end face " D " and the sealing surface that groove end face is formed are tight
It is closely connected to close, form tight envelope.
There are gap between " D " the type sealing ring lateral surface and groove lateral surface, the deformation for " D " type sealing ring is provided
Space.
The utility model has the advantages that the present invention has rational design, easy to operate, sealing effect is good, can be widely used in high pressure, ultra high pressure gas

Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
Fig. 1 show schematic structural view of the invention.
The present invention provides a kind of novel seals to silk component, including connecting pipe 1, " D " type sealing ring 2 and sealing are to silk
3。
The screw thread 31 of the sealing to silk 3 including both ends and the hexagonal between two sections of screw threads 31 are described to silk head 31
Hexagonal is to being respectively equipped with groove 33 on 31 two sides of silk head.
The groove 33 includes groove medial surface 331, groove lateral surface 332 and groove end face 333.
Fig. 2 show the schematic cross-section of " D " type sealing ring of the invention.
The section of " D " the type sealing ring 2 be " D " shape structure, should " D " shape structure include " D " type sealing ring medial surface 21,
" D " type sealing ring arc surface 22, " D " type sealing ring end face 23 and " D " type sealing ring lateral surface 24, wherein " D " type sealing ring circle
Cambered surface 22 and " D " type sealing ring end face 23 are located at the two sides of " D " type sealing ring 2.
Fig. 3 show present invention sealing to the structure principle chart of silk and " D " type sealing ring.
" D " the type sealing ring 2 is separately positioned on hexagonal and divides in 31 grooves on two sides 33 of silk head, with two connecting pipes 1
It Xing Cheng not be threadedly coupled.
The groove medial surface 331 is bonded to form sealing surface with " D " type sealing ring medial surface 21, groove end face 333 and " D "
The fitting of type sealing ring end face 23 forms sealing surface.
Fig. 4 show working state schematic representation of the invention.
For instrumental purpose when hexagonal is to silk head 31, sealing is threadedly coupled silk 3 with the formation of connecting pipe 1, while squeezing " D "
