Description

Technical Field

[0001] This utility model belongs to the field of compression fitting technology, specifically a high-temperature and high-pressure resistant compression fitting. Background Technology

[0002] Compression fittings are indispensable key components in piping systems for hydraulics, pneumatics, petrochemicals, and high-temperature steam. Their core function is to achieve reliable connection and sealing between pipes and equipment or between pipes themselves. In high-end industrial fields such as energy, aerospace, and semiconductor manufacturing, piping systems often need to transport media such as high-temperature heat transfer oils, supercritical fluids, and high-pressure steam.

[0003] Traditional compression fittings typically rely on tightening the nut to cause the ferrule to deform plastically, thereby gripping the pipe and achieving a seal. However, under long-term high-temperature conditions, the material will creep, causing the initial clamping force of the ferrule to loosen, which in turn leads to seal failure and leakage risks. Furthermore, in high-pressure environments, especially those with pressure pulses and mechanical vibrations, the single threaded locking method may gradually loosen due to vibration, reducing the stability and reliability of the fitting and becoming a potential hazard to system safety. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a high-temperature and high-pressure resistant compression fitting, which effectively solves the problems mentioned in the background.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention involves bringing a T-shaped rod close to the connector body, allowing the transverse groove to fit onto the semi-fixed column. A first spring then pushes a sliding block to slide, which in turn moves the semi-fixed column to slide and abut against the transverse groove. A second spring then pushes the semi-push column to further connect with the transverse groove. Bolts are then installed into the sliding block for fixation. An I-shaped plate is inserted into the I-shaped groove, and a damping rod in the bayonet pushes a pusher plate to move, which then fits tightly against the connecting groove and slot. This double reinforcement of the connection force between the nut and the side connecting column improves stability and effectively enhances the high-pressure resistance. Attached Figure Description
