AI Technical Summary

Technical Problem

During long-term use, the dust-proof structure and sealing structure have aging due to wear during long-term use, resulting in problems such as air leakage and liquid leakage.

Method used

An ultra-low temperature valve seat with multiple dust-proof treatment structure is designed. The connecting plate is driven by the drive shaft, and the fixed block and limit block are driven by the curved rod and the rotating shaft to slide to realize the secondary fixation and sealing of the pipe; at the same time, the first connecting pipe and the valve seat pipe slide into the sealing groove, combining the sealing strip and the dust-proof gasket, achieving multi-layer sealing and dust-proof effect.

Benefits of technology

Effectively prevent dust and impurities from entering, extend the service life of the valve, ensure the reliability and safety of the equipment, and avoid air and liquid leakage caused by frozen cracks and damage to the sealing structure.

Abstract

The utility model relates to the technical field of ultra-low temperature valve seat dust prevention, and discloses an ultra-low temperature valve seat with a dust-proof processing structure, which comprises a dust-proof shell, the inner wall of the dust-proof shell is rotatably connected with a driving shaft, the bottom end of the driving shaft is fixedly connected with a connecting plate, the inner wall of the connecting plate is fixedly connected with a first rotating shaft, and the inner wall of the first rotating shaft is fixedly connected with a second rotating shaft. The outer wall of the first rotating shaft is rotationally connected with a curved bar, the outer wall of the first connecting pipeline and the outer wall of the valve seat pipe are both slidably connected to the inner wall of the dustproof shell, a first sealing groove is formed in the inner wall of the first connecting pipeline, a sealing strip is fixedly connected to the inner wall of the first connecting pipeline, and a dustproof assembly is arranged on the outer wall of the first connecting pipeline. According to the pipeline fixing device, the driving shaft drives the connecting plate to rotate, the connecting plate drives the cranked lever and the first rotating shaft to drive the second rotating shaft to drive the fixing block, the fixing block and the limiting block slide under the limiting of the first sliding groove, and the effects of secondary fixing, sealing and dust prevention on a pipeline can be rapidly achieved.
