Abstract
The present invention relates to a kind of band neck slip-on-welding plate flange, it includes flange body（1）, the flange body（1）Cross section is in annular shape, the flange body（1）It is upper that inner radius is provided with projection（4）, the projection（4）In annular shape, the flange body（1）On be respectively arranged with exit orifice from outside to inside（2）And endoporus（3）, the exit orifice（2）At least two, the endoporus（3）At least two.A kind of band neck slip-on-welding plate flange of the invention so that two connections between equipment or pipe are more firm, reduce equipment or the repair rate of pipe, extend its service life.
Description
Technical field
The present invention relates to a kind of flange, a kind of band neck slip-on-welding plate flange is specifically related to.
Background technology
Flange, is called flange flange disk or bead.Flange is the part being connected with each other between pipe and pipe, for the connection between pipe end；Also have with the flange imported and exported in equipment, for the connection between two equipment, such as reductor flange.Traditional flange is made up of flange body and collar aperture eye, is connected between equipment not enough firmly, the time, long rear bolt easily came off.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided a kind of band neck slip-on-welding plate flange being connected firmly.
The object of the present invention is achieved like this：A kind of band neck slip-on-welding plate flange, it includes flange body, the flange body cross section is in annular shape, inner radius is provided with projection in the flange body, it is described raised in annular shape, exit orifice and endoporus, the exit orifice at least two, the endoporus at least two are respectively arranged with the flange body from outside to inside.
The internal diameter of the exit orifice is more than endoporus.
Compared with prior art, the invention has the advantages that：
A kind of band neck slip-on-welding plate flange of the invention so that two connections between equipment or pipe are more firm, reduce equipment or the repair rate of pipe, extend its service life.
Brief description of the drawings
Fig. 1 is a kind of structural representation with neck slip-on-welding plate flange of the present invention.
Wherein：
Flange body 1
Exit orifice 2
Endoporus 3
Projection 4.
Embodiment
Referring to Fig. 1, a kind of band neck slip-on-welding plate flange of the invention, it includes flange body 1, the cross section of flange body 1 is provided with projection 4, described raised 4 in annular shape in the flange body 1 in circular close to inner radius, exit orifice 2 and endoporus 3 are respectively arranged with from outside to inside in the flange body 1, the exit orifice 2 at least two, the endoporus 3 at least two, the internal diameter of the exit orifice 2 is more than endoporus 3.
The flange body 1 is made up of stainless steel, carbon steel or nickel steel.
