AI Technical Summary

Technical Problem

The existing fuel plant release panel device can only be triggered by a single temperature, which means it cannot be opened when the pressure exceeds the limit. In addition, the locking mechanism is not reliable enough, which can easily lead to gas leakage and inconvenience in maintenance.

Method used

Design a release panel device that can be triggered by both pressure and temperature. It adopts a door frame, door leaf, locking mechanism, hinge mechanism and sealing mechanism. It achieves dual-effect triggering unlocking through memory fused alloy and mechanical structure. Combined with stainless steel material and reasonable connection method, it ensures airtightness and convenient maintenance.

Benefits of technology

It enables automatic pressure relief when pressure or temperature exceeds the limit, ensuring the safety of the fuel plant, preventing gas leakage, simplifying maintenance operations, and adapting to complex operating conditions.

Abstract

The application discloses a release panel device capable of being triggered to open by pressure and temperature, which comprises a door frame, a door leaf, a locking mechanism, a hinge mechanism and a sealing mechanism. The release panel device can be triggered to unlock by pressure and temperature, solves the technical defects that the existing release panel can only be triggered to open by single temperature and is prone to overpressure of a fuel plant, and through the cooperation of the door frame, the door leaf, the locking mechanism, the hinge mechanism and the sealing mechanism, the integrity of the boundary of the fuel plant under normal operating conditions is ensured, and the door leaf can be quickly unlocked and pressure released under accident conditions. Meanwhile, the sealing mechanism ensures the airtightness of the door leaf under the closed state, prevents gas leakage and rainwater infiltration, is suitable for the complex working environment of the fuel plant, and provides basic guarantee for safe and stable operation of the fuel plant.
