Abstract
The utility model discloses a kind of pipe joint, comprises socket and running-on, it is characterized in that: described running-on is connected with jacksrew, has sealing ring between described running-on and socket, and described sealing ring outer wrap has hair fiber braiding layer.Described sealing ring body is O shape rubber seal or tetrafluoroethene sealing ring or carbon seal ring.Conventional seals circle is replaced with the sealing ring that outer wrap has hair fiber braiding layer by the utility model.Utilize large surface tension and the corrosion resistance of hair fiber, thus make the sealing ring of pipe joint aging or corrosion after still can ensure good sealing, substantially increase service life and the sealing effectiveness of pipe joint.
Description
Technical field
The utility model relates to a kind of pipe joint.
Background technology
The common form of existing pipe joint is the running-on and socket that are threaded, between running-on and socket, there is sealing ring, existing sealing ring material is varied, has quality of rubber materials, tetrafluoroethene material and graphite material etc., is applicable to different high temperature, high pressure, corrosive situations.But these sealing rings all can produce aging, corrosion in various degree in use for some time, cause leakage.
Summary of the invention
The utility model object is to provide a kind of good sealing effect for the defect of prior art, the pipe joint of long service life.
The utility model for achieving the above object, adopts following technical scheme:
A kind of pipe joint, comprise socket and running-on, it is characterized in that: described running-on is connected with jacksrew, have sealing ring between described running-on and socket, described sealing ring outer wrap has hair fiber braiding layer.
It is further characterized in that: described sealing ring body is O shape rubber seal or tetrafluoroethene sealing ring or carbon seal ring.
Conventional seals circle is replaced with the sealing ring that outer wrap has hair fiber braiding layer by the utility model.Utilize large surface tension and the corrosion resistance of hair fiber, thus make the sealing ring of pipe joint aging or corrosion after still can ensure good sealing, substantially increase service life and the sealing effectiveness of pipe joint.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Fig. 2 is ring structure schematic diagram.
Detailed description of the invention
A pipe joint as shown in Figure 1, comprises socket 4 and running-on 3, and described running-on 3 is connected with socket 4 spiral, has sealing ring 1 between described running-on 3 and socket 4, and described sealing ring 1 outer wrap has hair fiber braiding layer 2(as shown in Figure 2).Described sealing ring 1 body is O shape rubber seal or tetrafluoroethene sealing ring or carbon seal ring.
Because sealing ring outer wrap has hair fiber braiding layer.Utilize the large surface tension of hair fiber greatly can improve the sealing effectiveness of sealing ring.Simultaneously when sealing ring body in use for some time aging, corrosion time, hair fiber due to outside has good corrosion resistance and sealing effectiveness, at this moment whole sealing ring can also carry out good sealing, thus substantially increases sealing effectiveness and the service life of whole pipe joint.
Claims (2)
1. a pipe joint, comprises socket and running-on, it is characterized in that: described running-on is connected with jacksrew, has sealing ring between described running-on and socket, and described sealing ring outer wrap has hair fiber braiding layer.
2. pipe joint according to claim 1, is characterized in that: described sealing ring body is O shape rubber seal or tetrafluoroethene sealing ring or carbon seal ring.
