Abstract
The invention discloses a sealing ring for a stainless steel pipe fitting. The sealing ring for the stainless steel pipe fitting is made of an elastic material and has a circular ring shape and an L-shaped section. The invention has the advantages that: the sealing ring for the stainless steel pipe fitting has high strength, turns and does not deform or move, and is convenient to mount and obvious in sealing effect.
Description
Technical field
The present invention relates to a kind of seal ring, particularly a kind of stainless steel pipe is used seal ring.
Background technique
Thin-wall stainless steel water pipe, pipe fitting are the novel building materials of China's developed recently top grade of getting up, and the connection between this type tubing usually will be adopted seal ring, to prevent phenomenon such as leak.Present more employing be the rubber flat plate rectangular seal, the end plane that connects through outside thread conversion moves the extruding aftershrinkage of crossover sub plane with nut and seals, to reach sealing effect.But existing rubber flat plate rectangular seal material is soft; Occurring the outside thread crossover sub in actual use turns to nut and moves the crossover sub plane; When two ends are stressed; The rubber flat plate rectangular seal can be followed outside thread crossover sub end and rotated, and causes seal ring distortion, displacement, thereby influences sealing effect.
Summary of the invention
The problem that the present invention will solve is the deficiency that overcomes in the background technique, provides a kind of stainless steel pipe to use seal ring, and this stainless steel pipe is used seal ring; Be circular, adopt polytetrafluoroethylmaterial material to process, intensity is high; Its sectional shape is " L " type; Easy for installation, transfer but can not be out of shape, be shifted, sealing effect is obvious.
For addressing the above problem, the present invention takes following technological scheme:
A kind of stainless steel pipe of the present invention is used seal ring; Processed by the elastic material polytetrafluoroethylmaterial material, in the form of a ring, its sectional shape is " L " type; The external diameter of one end is slightly less than the internal diameter of pipe; Be convenient to easily put into inside tube, the external diameter of the other end moves the minor diameter of thread of crossover sub greater than the internal diameter of pipe less than nut.
A kind of stainless steel pipe of the present invention is used seal ring, is circular, owing to adopt the elastic material polytetrafluoroethylmaterial material to process; Therefore and its sectional shape is " L " type, has the intensity height, transfer but can not be out of shape, be shifted; Easy for installation, the tangible advantage of sealing effect.
Description of drawings
Fig. 1 is a cross-sectional view of the present invention.
Embodiment
As shown in Figure 1, a kind of stainless steel pipe of the present invention is used seal ring, is circular, and its sectional shape is " L " type, is processed by elastic material, and said elastic material is a teflon.
During manufacturing, the external diameter of 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, but moves the minor diameter of thread of crossover sub less than nut.
This stainless steel pipe is used seal ring, and intensity is high, transfer but can not be out of shape, be shifted, and sealing effect is obvious.
Claims (3)
1. a stainless steel pipe is used seal ring, it is characterized in that: said seal ring is circular, and its sectional shape is " L " type.
2. a kind of stainless steel pipe according to claim 1 is used seal ring, it is characterized in that: said seal ring is processed by elastic material.
3. a kind of stainless steel pipe according to claim 2 is used seal ring, it is characterized in that: said elastic material is a teflon.
