Double-ring pressing type B-shaped sealing ring for metal pipeline connection

Technical Field

The utility model relates to a double ring pressure formula B type sealing washer of usefulness is connected to metal pipeline.

Background

The sealing ring is generally used in some connecting parts requiring a sealing condition, and is used in many connections between pipes and pipe fittings, so that leakage can be prevented by the sealing ring.

However, the existing sealing ring is generally a simple O-shaped or flat type, the sealing effect is relatively general, and in the using process, the sealing ring may be damaged and aged due to long-term washing and temperature change, so that the sealing function is lost, and liquid or gas in the pipe fitting leaks.

There is therefore a need for a sealing ring that is capable of multiple leak prevention.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a double ring pressure formula B type sealing washer that metal pipeline connects usefulness to prior art's not enough.

In order to realize the purpose, the utility model adopts the technical proposal that: including the sealing washer, the sealing washer is including two tip, two the tip periphery all is equipped with first bulge loop and second bulge loop, first bulge loop with be equipped with the recess between the second bulge loop, the summit position of first bulge loop arrives the summit position distance of second bulge loop is X.

Preferably, the first convex ring, the groove and the second convex ring are all arc-shaped in cross section, the cross-sectional arc radius of the first convex ring is equal to that of the second convex ring, and the cross-sectional arc radius of the groove is smaller than that of the first convex ring and that of the second convex ring.

Preferably, the distance range of X: x is more than or equal to 5mm and less than or equal to 15 mm.

Preferably, the seal ring is made of rubber.

The utility model has the advantages that:

the utility model discloses a double ring pressure formula B type sealing washer that metal pipeline connects usefulness utilizes the elasticity compression ratio principle of sealing washer, and the sealing washer periphery is equipped with first bulge loop and second bulge loop, lead to the fact deformation to the sealing washer through the extrusion when the installation, thereby make the area of contact of sealing washer bigger, frictional force also can be bigger, it is more firm to make the installation, and there are first bulge loop and the double seal of second bulge loop, the leakproofness has been improved, consequently, guarantee one more, the emergence of seepage has been prevented, and wider than conventional seal ring face, service life is also longer.
