Abstract

The utility model relates to a long neck welding neck flange lid, including lid and cock body, be equipped with the recess on the cock body, the lid is established on the lateral wall of cock body, the lid is close to the notch department setting of recess, be equipped with a plurality of annular lugs on the lateral wall of cock body, be equipped with the strengthening rib between the lateral wall of annular lug and cock body, the strengthening rib is around a plurality of settings in the axle center of cock body, be equipped with the breach that "V" type set up on the strengthening rib. The utility model has the advantages that: the reinforcing ribs effectively improve the connection strength between the annular convex blocks and the plug body, so that the annular convex blocks are not easy to break; the notch that "V" type set up enables the strengthening rib and has certain deformation volume, makes annular lug buckle easily, and is more light when the dismouting is gone into in the flange.

Description

Long-neck butt welding flange cover

Technical Field

The utility model relates to a flange protection field, in particular to long neck butt welding blind flange.

Background

The sealed face of flange need use the blind flange to protect in the transportation of flange and storage process, prevents to take place to collide with between the flange and leads to the leakproofness decline of its sealed face, can also prevent that impurity such as outside dust from getting into inside, influences the normal use of flange. However, the existing flange cover generally adopts an insertion connection mode, and after a long time, the connection between the annular bump on the flange cover and the plug body is easily broken or damaged, so that the connection between the flange cover and the flange is unstable, the sealing performance is reduced, and the service life is relatively short.

SUMMERY OF THE UTILITY MODEL

To the deficiencies of the prior art, an object of the utility model is to provide a long neck butt welding blind flange to solve above-mentioned problem.

The technical scheme of the utility model is realized like this: the utility model provides a long neck welding neck flange lid, includes the lid and the cock body, be equipped with the recess on the cock body, the lid is established on the lateral wall of the cock body, the notch department that the lid is close to the recess sets up, be equipped with a plurality of annular lugs on the lateral wall of the cock body, be equipped with the strengthening rib between the lateral wall of annular lug and the cock body, the strengthening rib is around a plurality of settings in the axle center of the cock body, be equipped with the breach that "V" type set up on the strengthening rib.

By adopting the technical scheme, the reinforcing rib effectively improves the connection strength between the annular convex block and the plug body, so that the annular convex block is not easy to break; the notch that "V" type set up enables the strengthening rib and has certain deformation volume, makes annular lug buckle easily, and is more light when the dismouting is gone into in the flange.

The utility model discloses further set up to: be equipped with solid fixed ring on the lateral wall of recess, gu fixed ring's upside is equipped with the magnet, gu fixed ring is close to the notch setting of recess.

Through adopting above-mentioned technical scheme, because the flange generally all adopts the iron material preparation, inhale the iron stone and can effectually fix the blind flange and adsorb in the flange, improved joint strength.

The utility model discloses further set up to: the upside of magnet is equipped with the spacing ring, the lateral wall fixed connection of spacing ring and recess, the magnet is inserted and is connected between solid fixed ring and spacing ring.

Through adopting above-mentioned technical scheme, can fix the magnet in the recess, make it be difficult for droing.

The utility model discloses further set up to: the limiting ring is made of rubber.

Through adopting above-mentioned technical scheme, the rubber material has made things convenient for the packing into of magnet, makes its installation light more.

The utility model discloses further set up to: the plug body is in a circular truncated cone shape.

By adopting the technical scheme, the plug body arranged in the shape of the circular truncated cone facilitates the plug body to be plugged into the flange, so that the plug body is easier to install.

The utility model discloses further set up to: the bottom end of the notch is arranged towards the joint of the annular convex block and the plug body.

Through adopting above-mentioned technical scheme, make annular lug more stable when buckling, better with the connected effect between the flange.
