Problems solved by technology

[0002] Asphalt needs to use a large number of pipelines in the process of transportation, and the connection between pipelines needs to be connected by flanges. Traditional flanges improve the distance between flanges by setting a sealing ring between the two flanges. Sealing effect, but after a long time of use, the sealing ring will age, the sealing effect cannot be guaranteed, it cannot play the role of sealing, and it is prone to leakage

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 The shown asphalt pipeline connection flange is characterized in that it includes a left flange 1 and a right flange 7 used in conjunction with it. The outer peripheral surface of the annular sealing protrusion 4 is an inclined surface 3, the end surface of the right flange 7 is provided with a sealing groove 5 that cooperates with the annular sealing protrusion, and the bottom of the sealing groove 5 is provided with a sealing Circle 8.

[0014] The edge of the flange of the left flange is provided with a connecting groove 2, and the edge of the flange of the right flange is provided with a mounting groove, and a rotatable connecting bolt 6 is arranged in the mounting groove. When installing, the connecting bolt 6 is locked. into the connection groove 2 and fixed by nut locking.

[0015] In summary, the present invention has the following be...

Abstract

The invention belongs to the fitting field of asphalt production equipment, and particularly relates to a connecting flange for asphalt conveying pipelines. The connecting flange for asphalt pipelines is characterized by comprising a left flange and a right flange cooperatively used with the left flange, wherein an annular sealing bulge is arranged on the end face of the left flange; the peripheral face of the annular sealing bulge is an inclined surface; a sealing groove matched with the annular sealing bulge is formed in the end face of the right flange; a seal ring is arranged at the bottom of the sealing groove. The flange disclosed by the invention has a good practical sealing effect; moreover, the locking mode between the flanges is improved, and the flanges are convenient for quick locking connection, so that the installation time is shortened, and the installation efficiency of workers is improved.

Description

technical field [0001] The invention belongs to the field of accessories for asphalt production equipment, in particular to a connecting flange for asphalt conveying pipelines. Background technique [0002] Asphalt needs to use a large number of pipelines in the process of transportation, and the connection between pipelines needs to be connected by flanges. Traditional flanges improve the distance between flanges by setting a sealing ring between the two flanges. Sealing effect, but after a long time of use, the sealing ring will age, the sealing effect cannot be guaranteed, it cannot play the role of sealing, and it is prone to leakage. Contents of the invention [0003] The present invention aims at the deficiencies of the prior art, and the present invention designs a set of pipeline connection flanges for use together. The flanges described in the present invention have a good sealing effect in combination with practicality. In addition, the present invention has a lo...
