SAE flanges also known as flanges or flanges flanges are shaft-to-shaft interconnecting parts used for connection between pipe ends; In addition, there are flanges that facilitate the inlet and outlet of equipment used for connecting two equipment, such as reducer flanges Sae flange connection or flange joint refers to the detachable connection of combined sealing structure in which flange gasket and bolt are connected with each other. Integral flange and split flange are two types of flanges, which are mainly used in the coordination of hydraulic machinery and pipeline Easy to install and easy to disassemble the characteristics of the following together to understand the advantages of the one-way valve sae flange bar!

At present, if a split sae flange is used to clamp the end of the pipeline on the market, it must be connected with an integral flange to connect to the next pipeline. In this process, a line coupling is used that is connected to an integral flange at one end and to the pipeline at the other end with a butt weld. In the welding process, the flange joint port is directly welded with the oil delivery pipe oil hole, which has defects. One is that welding requires at least two people to operate, one supports and clamps the entire flange joint, and the other corrects the position of the oil pipe joint and the oil hole for welding. High labor cost and high labor intensity. The second is that when the entire flange joint is manually supported and clamped, the oil pipe joint is easily misplaced due to vibration and extrusion during welding, and the welding quality is unqualified. The third is the welding slag generated during welding. Because of the welding method, these welding slags are easy to fall into the pipeline from the oil hole, causing oil circuit pollution and even oil circuit blockage.

Implementation elements of sae flange technology:

The purpose of the sae flange is to overcome the defects of the existing technology. The method of direct butt welding between the port of the traditional oil pipe joint and the oil passage hole of the oil pipeline is high in cost and labor-intensive. Vibration and extrusion during welding will easily cause the misalignment of the oil pipe joint and weld slag It is easy to fall into the oil pipeline from the oil hole, causing oil pollution

sae flange In order to achieve the above purpose, the utility model adopts the following technical solutions.

The sae flange is equipped with an integral flange, the integral flange is in the middle of the through hole a in the front and back, and an annular stepped groove is embedded in the hole wall at the rear end of the through hole a, and the flange joint penetrates through the through hole a , the flange joint is an integrated group consisting of snap ring, stop pipe, extension pipe and snap ring from the rear. snaps securely into the annular stepped groove of the flange

The outer diameter of the sae flange snap ring is larger than the stop pipe, the outer diameter of the stop pipe is larger than the extension pipe, the outer diameter of the extension pipe is larger than the snap ring, and a chamfer c2 is provided between the stop pipe and the extension pipe. There is a chamfer c1 between the pipe and the snap ring

Compared with the prior art, the sae flange has the beneficial effects of the utility model as follows

1. In the sae flange joint provided by the utility model, the hole wall located at the rear end of the through hole a is embedded in the annular stepped groove, and the snap ring is just stuck in the annular stepped groove, and the annular stepped groove in the combined flange is firmly defined. Blue joints, there will be no misalignment of front, back, left, and right. 2. The sae flange joint provided by the utility model has a chamfer c2 between the stop pipe and the extension pipe, one is to reduce the outer diameter of the extension pipe and reduce the use of materials, and the other is to make the flange pipe The joints are more aesthetically pleasing.

3. The sae flange joint provided by the utility model has a chamfer c1 between the extension tube and the adapter ring, and a loading ring between the front end of the chamfer c1 and the rear end of the adapter ring. Due to the existence of chamfer c1, the welding operation between the loading ring and the oil hole on the pipeline becomes easy and convenient, and due to the existence of the loading ring, the welding joint between the flange joint and the pipeline becomes tighter and firmer.

4. The sae flange joint provided by the utility model is provided with a clamping groove in the middle of the left and right sides of the integral flange and the assembly flange. The overall clamping force of the joint is more stable during welding.

5. In the sae flange joint provided by the utility model, the fastening screw passes through the through hole and the screw hole is installed inside. The single-sided fastening method is used to butt and fix the combined flange and the integral flange, which changes the traditional multi-wrench fastening method in which bolts and nuts are fastened to each other, making the operation simpler and more convenient, and reducing the difficulty of operation.

6. The sae flange oil pipe joint provided by the utility model, when the flange oil pipe joint is connected with the oil pipeline, the fastening retaining ring is just inserted into the oil hole of the oil pipeline, avoiding the oil pipe joint dislocation caused by vibration and extrusion during welding Problem; In addition, because the loading ring is just carried on one end of the oil hole, the welding slag generated during welding will not fall into the pipeline, which avoids the problems of oil circuit pollution and oil circuit blockage.

7. The sae flange pipe joint provided by this utility model has changed the traditional pipe butt welding method, and the fastening ring is inserted into the pipeline for welding. The flange pipe joint is easy to operate, and the operator can control the welding to realize single-person work.

The above are the advantages of the one-way valve sae flange. If you need to know more, please feel free to contact us!
