Abstract
The invention discloses an anti-loose seal ring which is annular. The cross section of the anti-loose seal ring is in an L shape. The large face of the anti-loose seal ring is made into a radiation wave shape. The anti-loose seal ring is made of elastic material, namely, polytetrafluoroethylene. The anti-loose seal ring is tight and reliable in connecting and sealing and has the advantages of being easy to manufacture and convenient to use.
Description
Technical field
The present invention relates to a kind of seal ring, the locking seal ring that particularly a kind of stainless steel pipe is used.
Background technique
At present; thin-wall stainless steel water pipe, pipe fitting are when connecting; more employing rubber flat plate rectangular seal; but existing rubber flat plate rectangular seal material is soft; in assembly process; rubber flat plate rectangular seal can be followed external thread switching adapter end and be rotated, and causes sealed ring deformation, displacement, thereby affects sealing effect.
Summary of the invention
The problem to be solved in the present invention is the deficiency overcoming in background technique, and a kind of locking seal ring is provided, and this locking seal ring, adopts special end-face structure, makes its sealing closely, reliably.
For addressing the above problem, the present invention takes following technological scheme:
A kind of locking seal ring of the present invention, is circular, and its sectional shape is " L " type, and the larger one side of described locking seal ring makes that radiation is wavy, and described locking seal ring is made by elastic material, and described elastic material is teflon.The external diameter of locking seal ring one end is slightly less than the internal diameter of pipe, is convenient to easily put into inside tube, and the external diameter of the other end is greater than the internal diameter of pipe, is less than the minor diameter of thread that nut moves crossover sub.When assembling compresses, the wavy one side extrusion of locking seal ring radiation, its spring-back force and nut move crossover sub and interact, and have realized sealing tight, reliable.
A kind of locking seal ring of the present invention, due to the larger one side of locking seal ring, to make radiation wavy, and locking seal ring is made by elastic material teflon.Therefore, the locking seal ring of this invention has not only been realized and has been connected sealing closely, reliably, but also has advantages of easy manufacture, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic top plan view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, a kind of locking seal ring of the present invention, is circular, and its sectional shape is " L " type, and it is wavy that the larger one side of described locking seal ring is made radiation.
Described locking seal ring is made by elastic material.
Described elastic material is teflon.
Should be noted that; the foregoing is only the preferred embodiments of the present invention, be not limited to the present embodiment, within the spirit and principles in the present invention all; any modification of doing, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
Claims (3)
1. a locking seal ring, is circular, and its sectional shape is " L " type, it is characterized in that: it is wavy that the larger one side of described locking seal ring is made radiation.
