Abstract
The invention discloses a novel pipe joint, which includes a spigot and a muzzle bell. The novel pipe joint is characterized in that the spigot and the muzzle bell are spirally connected, a sealing ring is arranged between the spigot and the muzzle bell, a ring-shaped groove is formed on a seal contact surface of the sealing ring and filled with hair fiber woven rings, and a sealing ring body is an O-shaped rubber sealing ring, a tetrafluoroethylene sealing ring, or a carbon sealing ring. The novel pipe joint has the advantages that an ordinary sealing ring is replaced by the sealing ring with the hair fiber woven rings, so that through the large surface tension and high corrosion resistance of hair fibers, the sealing ring of the pipe joint can still guarantee good leakproofness when aged or corroded, which greatly prolongs the service life of the pipe joint and improves the sealing effect of the pipe joint.
Description
Technical field
The present invention relates to a kind of new tube joint.
Background technique
The common form of existing pipe joint is the running-on and socket that are threaded, between running-on and socket, there is seal ring, existing seal ring material is varied, has quality of rubber materials, tetrafluoroethylene material and graphite material etc., is applicable to different high temperature, high pressure, corrosive situations.But these seal rings all can produce aging, corrosion in various degree in use for some time, cause leakage.
Summary of the invention
The object of the invention is to provide a kind of good sealing effect for the defect of prior art, the new tube joint of long service life.
The present invention for achieving the above object, adopts following technological scheme:
A kind of new tube joint, comprise socket and running-on, it is characterized in that: described running-on is connected with jacksrew, between described running-on and socket, there is seal ring, described seal ring sealing contact surface has annular recess, in described annular recess, is filled with hair fiber braided ring.
It is further characterized in that: described seal ring body is O shape rubber seal or tetrafluoroethylene seal ring or carbon seal ring.
Conventional seals circle is replaced with the seal ring with hair fiber braided ring by the present invention.Utilize large surface tension and the corrosion resistance of hair fiber, thus make the seal ring of pipe joint aging or corrosion after still can ensure good sealing, substantially increase working life and the sealing effect of pipe joint.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is O type coil structures schematic diagram.
Fig. 3 is tetrafluoroethylene seal ring or carbon seal ring structural representation.
Embodiment
A kind of new tube joint as shown in Figure 1, comprise socket 4 and running-on 3, described running-on 3 is connected with socket 4 spiral, has seal ring 1 between described running-on 3 and socket 4, described seal ring 1 sealing contact surface has annular recess, in described annular recess, is filled with hair fiber braided ring 2.As shown in Figure 2,3, described seal ring 1 body is O shape rubber seal or tetrafluoroethylene seal ring or carbon seal ring.
Because seal ring has hair fiber braided ring.Utilize the large surface tension of hair fiber greatly can improve the sealing effect of seal ring.Simultaneously when seal ring body in use for some time aging, corrosion time, hair fiber due to outside has good corrosion resistance and sealing effect, at this moment whole seal ring can also carry out good sealing, thus substantially increases sealing effect and the working life of whole pipe joint.
Claims (2)
1. a new tube joint, comprise socket and running-on, it is characterized in that: described running-on is connected with jacksrew, between described running-on and socket, there is seal ring, described seal ring sealing contact surface has annular recess, in described annular recess, is filled with hair fiber braided ring.
2. new tube joint according to claim 1, is characterized in that: described seal ring body is O shape rubber seal or tetrafluoroethylene seal ring or carbon seal ring.
