AI Technical Summary
During the processing process, the flange connection joints are prone to dimensional deviation, resulting in uneven clearance of the oil pipe joints, increasing the pressure of the O-ring, which easily leads to the O-ring being broken down by high-pressure oil, causing leakage problems, affecting equipment efficiency and O-ring. The service life of the circle.
A special anti-leakage assembly for flange oil pipe joints is designed, including two semi-rings anti-leakage assembly, which is arranged between the oil pipe joint and the stress surface of the flange clip, covering the O-ring to ensure that it is Balanced force to enhance compaction effect.
It improves the compaction effect of the O-ring, reduces the leakage problem of the oil pipe joint, extends the service life of the O-ring, and reduces the equipment failure rate. It is suitable for large diameter and high pressure flange connecting oil pipe joints.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flange type oil pipe joints, and more specifically, particularly belongs to a special anti-leakage component for flange type oil pipe joints. Background Art
[0002] The hydraulic system oil pipe joints of the bucket wheel mechanism of the bucket wheel stacker reclaimer adopt flange connection. However, there are dimensional deviations in the production and processing of flange connection joints. There is an installation gap of about 1mm between the split flange clamp and the oil pipe flange connection plate. Due to the processing deviation of the oil pipe disc or the split flange clamp, the installation gap is sometimes too small. At the same time, because the main oil pipe of the bucket wheel system has a large diameter and the pipeline oil pressure is high, in order to prevent the oil pipe joint from leaking oil, the tightening torque required for the connecting bolts between the oil pipe flange and the split flange clamp is very large, which causes the split flange to deform. At some joints with small flange installation gaps, the two ends of the split flange clamp contact the installation flange, resulting in the flange O-ring not being pressed firmly, which is very likely to cause the O-ring to be pierced by high-pressure oil.
[0003] A damaged O-ring will cause serious oil leakage at the joint, requiring the machine to be shut down to replace the O-ring. The maintenance time is long and refueling is required, which affects the operating efficiency of the process equipment. In addition, the O-ring has a short service life and needs to be replaced frequently. Summary of the invention

[0005] The utility model provides a special anti-leakage component for flange-type oil pipe joints, comprising an oil pipe joint, an oil pipe flange, a split flange clamp and an O-ring; the oil pipe flange and the split flange clamp are threadedly fitted and fixed; the oil pipe joint is connected and fixed to the oil pipe flange by clamping the split flange clamp; the O-ring is arranged between the oil pipe joint and the oil pipe flange, and is characterized in that it also includes an anti-leakage component; the anti-leakage component is two semicircular rings, which are arranged between the oil pipe joint and the stress-bearing surface of the split flange clamp.
[0006] The utility model provides a special anti-leakage component for a flange type oil pipe joint, which is designed with an anti-leakage component.
