Abstract
The utility model discloses a novel threaded sealing structure which comprises a screw head (1) and a threaded part (2), wherein the threaded part (2) is provided with an annular groove structure (3), and a polytetrafluoroethylene sealing ring (4) is arranged inside the annular groove (3). Through the adoption of the structure, the novel threaded sealing structure has the advantages of high sealing reliability and low cost. Since the polytetrafluoroethylene is adopted as filling materials, the novel threaded sealing structure is nontoxic, and can resist against acid, the temperature between -180 DEG C and 250 DEG C and aging. The sealing ring is pre-processed on the screw head, and is directly connected during the installation without adopting other sealing measures, the installation is fast and convenient, and the assembly operation on the production line can be realized favorably.
Description
Technical field
The utility model relates to a kind of thread seal structure, especially relates to a kind of novel thread seal structure that need not use thread locking adhesive.
Background technique
At present, adopt thread locking adhesive to be coated on the screw thread more, be used for sealing and fixing metal pipeline and pipe fitting, fill the space between the metal parts screw thread for thread seal, and solidifying the leakage of rear defence stopping leak, to play sealing effect.This thread seal structure not only sealing effect is not good, and needs certain curing time, has influenced assembling speed and working efficiency.In addition, because thread locking adhesive is chemical coating material, in use also can pollute Assembly part and even befouling environment.
Summary of the invention
The purpose of this utility model provides the reliable novel thread seal structure of a kind of sealing effect.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises spiral shell head and helical thread portion, it is characterized in that described helical thread portion is provided with circular groove structure, is provided with teflin ring in the annular groove.
The beneficial effects of the utility model are:
1, the filled sealing means of screw thread, the sealing reliability height, and with low cost;
2, make filler with teflon, nontoxic, antiacid, heatproof can reach-180 ℃-250 ℃, environmental protection, anti-aging;
3, seal ring is processed in advance on the spiral shell head, directly connects during installation, need not take other seal approach, and is quick and convenient, is very beneficial for the production line assembly manipulation.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Figure 1 shows that structural representation of the present utility model
Figure 2 shows that the utility model screw thread screws the schematic representation that thread pitch is filled in back seal ring distortion
Embodiment
By accompanying drawing as can be known, this novel thread seal structure comprises spiral shell head 1 and helical thread portion 2, and described helical thread portion 2 is provided with circular groove structure 3, is provided with teflin ring 4 in the annular groove 3.Helical thread portion at metal spiral shell head is processed one annular groove earlier, and spiral shell head groove is embedded in teflon annular seal ring, and seal ring and spiral shell head require fastening installation.When installing and using, along with the extruding of screw thread, the thread pitch part is filled in the distortion of teflon annular seal ring, thereby reaches the purpose of sealing.Seal ring of the present utility model can be processed in advance on the spiral shell head, when sealing is installed so directly screw thread screw.
Claims (1)
1. a novel thread seal structure comprises spiral shell head and helical thread portion, it is characterized in that described helical thread portion is provided with circular groove structure, is provided with teflin ring in the annular groove.
