Description

Technical Field

[0001] This utility model relates to the field of blind flange safety interlock technology, and in particular to a quick-opening blind flange safety interlock mechanism for pressure vessels. Background Technology

[0002] Pressure vessels are key equipment used in industrial production for storage, reaction, heat exchange and other processes. They are widely used in chemical, petroleum, pharmaceutical, food and energy fields. In order to facilitate internal maintenance, cleaning and material loading and unloading, many pressure vessels use quick-opening blind flanges as heads or end caps. The opening structure can significantly shorten equipment downtime and improve production efficiency.

[0003] Currently, most existing pressure vessel quick-opening blind flange safety interlock mechanisms are based on mechanical pins. The locking of existing devices relies on a single pin. Under equipment vibration, medium impact, or slight external force collision, the pin may loosen, and the clamp may slip, causing the blind flange surface to appear closed but not actually completely sealed. If pressure is applied to the vessel at this time, the medium may leak from the gaps or even push the blind flange off. Because there is no scale feedback, it is difficult for operators to determine whether the blind flange is fully locked. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a safety interlock mechanism for quick-opening blind flanges of pressure vessels, which aims to improve the problems of unstable locking state and uncontrollable depressurization speed in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a pressure vessel quick-opening blind flange safety interlock mechanism, comprising a hollow cylinder, a flange fixedly connected to the top of the hollow cylinder, a locking ring fixedly connected to the top of the flange, a rotating disk rotatably connected to the inner wall of the locking ring, a rotating block fixedly connected to the middle of the outer wall of the rotating disk, a fixed shaft fixedly connected to the inner wall of the rotating block, a connecting plate fixedly connected to the top of the fixed shaft, a bracket fixedly connected to the outer wall of the connecting plate, a rotating shaft rotatably connected to the outer wall of the bracket, a guide block fixedly connected to the outer wall of the rotating shaft, a locking ring fixedly connected to the outer wall of the guide block, and a pressure regulating mechanism fixedly connected to the outer wall of the hollow cylinder, the pressure regulating mechanism being used to regulate the pressure inside the container.

[0021] 1. In this utility model, the material enters the hollow cylinder and is fixedly connected to the locking ring by the flange. The rotating disk and the rotating block rotate synchronously and the fixed shaft is used for fixation. When the rotating disk is open, it rotates from right to left to move the protruding part out of the locking groove.

The rotating disk 5 and the rotating block 6 rotate synchronously, and the fixed shaft 7 is used for fixation. When the rotating disk 5 is open, it rotates from right to left, causing the protruding part to leave the locking groove. When the rotating disk 5 is closed, it rotates from left to right, causing the protruding part to rotate into the groove to achieve locking. The guide block 8 is fixedly connected to the locking ring 4, and the rotating shaft 9 is fixedly connected to the bracket 10.
