Preferably, the inner walls of the oil inlet and the pipeline connector are both sprayed with heat insulation coatings, so that the flange cannot be damaged when high-heat oil circulates in the pipeline, and accidents are caused.

Preferably, the small fixing holes are arranged in two, the large fixing holes are arranged in two and are in bilateral symmetry, it is ensured that the flange cannot rotate in the installation process, the installation time is saved, and the installation efficiency is effectively increased.

Compared with the prior art, the utility model has the beneficial effects that:

1. compared with the traditional flange using a metal sealing gasket, the oil pipe flange uses the rubber sealing gasket, so that the phenomenon of corrosion and rust caused by long-time use is avoided, the service life is prolonged, the rubber sealing gasket enables the connection between the flanges to be tighter, and the sealing property is greatly improved;

2. this oil pipe flange for traditional not have the flange that sets up the socket, through the jack that sets up for the screw can run through big fixed orifices, advances fixedly to the screw that passes in the big fixed orifices, has avoided long-time the use, appears not hard up phenomenon because of the screw and is collapsed the phenomenon of opening by intraductal high pressure.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: an oil pipe flange comprises a base 1, wherein a pipeline interface 7 is fixedly connected to the upper end of the base 1, an oil inlet 3 is formed in the bottom end of the base 1, a rubber sealing gasket 2 is fixedly connected to the bottom end of the base 1, a small fixing hole 4 and a large fixing hole 5 are fixedly connected to the upper end of the base 1, inserting holes 6 are fixedly connected to two ends of the base 1, the two flanges are connected more tightly through the small fixing hole 4 and the large fixing hole 5, the thickness of the rubber sealing gasket 2 is two millimeters higher than the horizontal plane of the base 1, so that the two flanges are more tightly attached to each other when connected, and the sealing property is greatly increased;
