Abstract
The utility model relates to a sealing part for oil and gas transmission pipelines, in particular to multi-layer spherical two-sided sealing rings. The sealing rings are arranged at the upper end and the lower end of a body of a device respectively. The sealing rings are made of graphite. The outer surface of each sealing ring is provided with multiple sealing ring strips. The outer surface of each sealing ring is designed to be in a cone shape and makes close contact with the contact surfaces of connected pipe fittings in a sealed mode. The multi-layer spherical two-sided sealing rings have the advantages that the sealing rings are not prone to damage, safe and reliable in sealing and convenient to replace and maintain, and the defects that an existing sealing part is prone to damage, a soft metal film on the surface of the sealing part is prone to being bound to the sealing surface, and the sealing part is hard to replace and maintain are overcome.
Description
Technical field:
The utility model relates to the Sealing that a kind of pipe-line is used, particularly a kind of multilayer ball-type dual face seals ring.
Background technique:
When oil drilling special oil feed channel is carried High Temperature High Pressure oil gas, the unable to bear impact of high temperature high pressure oil gas of its pipeline junction Sealing, easily damages, and seal surface soft alloy film is easily bonded on sealing surfaces, gives to change and maintenance brings difficulty.
Model utility content:
The technical problems to be solved in the utility model is to provide a kind of multilayer ball-type dual face seals ring, and this device has been realized not fragile, and sealingly secure is reliable, and repair and replacement are convenient.Overcome existing Sealing and easily damaged, seal surface soft alloy film is easily bonded on sealing surfaces, changes deficiency difficult in maintenance.
Technical solution adopted in the utility model is: a kind of multilayer ball-type dual face seals ring, is made up of seal ring and main body; The upper and lower two ends of main body are all provided with seal ring, and seal ring adopts graphite to make, and is designed with multiple-sealed endless belt on seal ring outer surface, and seal ring outer surface is designed to taper and seals with connecting tube surface of contact close contact.
The beneficial effects of the utility model are: the utility model is not fragile, and sealingly secure is reliable, and repair and replacement are convenient.
Brief description of the drawings:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is scheme of installation of the present utility model.
Embodiment:
As shown in Figure 1, a kind of multilayer ball-type dual face seals ring, is made up of seal ring 1 and main body 2; Main body is all provided with seal ring 1 in two ends Shang Xia 2, and seal ring 1 adopts graphite to make, and on seal ring 1 outer surface, is designed with multiple-sealed endless belt, and seal ring 1 outer surface is designed to taper and seals with connecting tube 3 surface of contact close contacts.
As shown in Figure 2, when use, the utility model is arranged on the end face of two connecting tubes 3, connecting tube 3 hole tapers coincide and contact with seal ring 1 outer surface, and clamp by slips 4, make pipe fitting be connected to form sealing.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technological scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as meet, all within protection domain of the present utility model.
