Description

High strength rand subassembly

Technical Field

The utility model belongs to the technical field of pipeline connecting fittings and relates to a high-strength clamping ring assembly.

Background

The pipeline connection mainly comprises three types of welding, clamping connection and clamping ring mechanical connection. The valve, the pipeline or the pipe joint are connected by welding, the pressure resistance and the drawing performance are good, but the technical requirement on operators is high, the requirement on space of welding operation is high, and the welding surface cannot be electroplated and the like; the press-fit connection product cannot be recovered. The clamping ring is mechanically connected by screwing the pipe fitting and the nut and extruding the clamping ring, so that the clamping ring deforms to hold the pipe fitting tightly and generates metal hard seal to realize connection, and the clamping ring is simple to operate and high in tensile strength, and is widely applied.

The rand among the current rand mechanical connection all adopts cyclic annularly, embolias the kneck in the kneck of connecting pipe or valve through operating personnel, and the nut locking of screwing again can, nevertheless current rand still probably is in not hard up state or after connecting pipe and valve use a period after the screw in locking, the rand can appear becoming flexible, can cause to reveal, influences the result of use, reduces its life.

Disclosure of Invention

It is an object of the present invention to address the above-mentioned problems of the prior art by providing a high strength collar assembly having a locking feature.

The purpose of the utility model can be realized by the following technical scheme: the utility model provides a high strength rand subassembly, a serial communication port, including the rand body that has the hole, the rand body be ring shape, rand body hole has the radial inside bellied bellying of a plurality of, a plurality of bellying central axis with rand body central line axis coincidence, a plurality of the bellying between have the contained angle, rand body internal perisporium on seted up installation annular and annular the installation annular in have the copper snap ring who is used for strengthening the joint strength, rand body periphery wall on be provided with the rubber circle, just the rubber circle including rand body outer peripheral face parcel, rubber circle side edge extend to rand body side and set up in port department annular tank bottom parallel and level rather than.

In foretell high strength rand subassembly, a plurality of bellying is the slope setting, and the contained angle that is located between a plurality of bellying is 13, and a plurality of bellying and rand body be integrated into one piece processing setting.

In foretell high strength rand subassembly, the rand body can adopt stainless steel, rand body periphery wall on offer the spacing annular of supplying the spacing installation of its rubber circle.

In the above mentioned high strength collar assembly, the inner peripheral wall of the rubber ring has a flange portion engaged with the stopper ring groove.

In foretell high strength rand subassembly, a plurality of bellying quantity be 6, and 6 contained angle quantity between the bellying is 6.

Compared with the prior art, this high strength rand subassembly has structural design rationally, reliable, with low costs, locking effectual and have good leakproofness, has solved the not hard up problem of rand installation with simple structure, has improved production efficiency and has reduced the cost.
