Description

High-new flange

Technical Field

The utility model relates to a pipe connection technical field, in particular to high-tech flange.

Background

The flange is a widely used pipeline connecting device, is visible everywhere in daily life and industrial pipelines when being applied to pipeline connection, and is widely used, for example, various valves such as ball valves, butterfly valves, gate valves, check valves and the like used in indoor fire hydrant water supply systems and devices such as nuclear power, petroleum, chemical engineering and the like are connected with the pipelines. In pipe work, flanges are mainly used for connection with pipes. At the two pipe ends, one flange is mounted for connection to other equipment (e.g., valves, etc.).

At present, the connection of a flange and a pipeline generally adopts welding connection, and the welding mode can be divided into butt welding, flat welding, socket welding and the like. For high-temperature, high-pressure and large-diameter pipelines, in order to ensure the weld penetration between a flange and the pipeline, when welding, a gap of 2-3 mm generally needs to be reserved between a welding cut on the flange and a pipeline welding cut, and meanwhile, the coaxiality of the welding cut must be ensured, otherwise, the welding seam bears extra bending stress after being connected with equipment, and potential safety hazards are brought to the operation of the equipment. The common flange can not be accurately positioned when being connected with a pipeline, so that the coaxiality and the gap requirement can not be ensured, and the welding seam quality is influenced. In recent years, major safety accidents caused by weld quality problems have occurred many times in various petrochemical enterprises.

For the large-diameter flange, in order to reduce the deviation as much as possible, other auxiliary equipment needs to be additionally added during construction, so that the efficiency is low, and a large amount of manpower and material resources are consumed.

Detailed Description

The present invention will be further described with reference to the following detailed description of preferred embodiments thereof, which is to be read in connection with the accompanying drawings.

First, a high and new flange according to an embodiment of the present invention will be described with reference to fig. 1 to 4, for use in connection with a pipeline 3, which has a wide application range.

As shown in FIGS. 1-4, the utility model discloses high-new flange has ring flange main part 1 and direction orientation module.

Specifically, as shown in fig. 1 to 2, in this embodiment, a bolt hole 11 is formed in the flange main body 1, the bolt hole 11 is used for fixedly connecting the flange main body 1 with other devices, a welding cut-out 12 is formed in one end of the flange main body 1, the welding cut-out 12 is welded with an external pipeline 3, and a guiding and positioning module is connected with the flange main body 1 and used for guiding and limiting the pipeline 3 during welding, so as to ensure that the axis of the pipeline 3 is concentric with the axis of the flange main body 1, thereby greatly improving the construction efficiency and improving the welding quality.

Further, as shown in fig. 1 to 4, in the present embodiment, the guiding and positioning module includes: a positioning slot 21 and a positioning block 22. Locating slot 21 is seted up on the neck outer wall of welding groove 12, locating piece 22 joint is on locating slot 21, locating piece 22 and locating slot 21's shape, the number phase-match, on locating piece 22 joint locating slot 21, can let locating piece 22 and the laminating of pipeline 3 in pipeline 3 and the 1 welded of ring flange main part, make axial and radial displacement between ring flange main part 1 and the pipeline 3 can fully fix, thereby can weld, accuracy nature when realizing the welding, and the construction efficiency is improved, the cost is saved, make welding operation more convenient, and the dismouting is more convenient.
