Abstract
The invention discloses a dangerous pressure releasing mechanism of a sealed pressure container. The problems that under the dangerous pressure, the sealed pressure container is not prone to being manually intervened, and an antiriot cover is not prone to being opened are solved. A pressure spring (13) is arranged to achieve the aim of opening a dangerous pressure cover under the condition without pressure; when an electromagnet is manually controlled to carry out attraction, an electromagnet sliding rod (17) rises upwards, limitation of a limiting steel ball (16) is relieved, the limiting steel ball falls in a piston pipe (14) of a conical piston (10), the conical piston (10) moves upwards, and the pressure spring (13) conducts pushing force to a wedge-shaped block (9) through an annular hood; and the wedge-shaped block (9) moves inwards to relieve limitation of a wedge-shaped block outer side limiting ring (5) to the wedge-shaped block (9), and opening of a sealed cover body is achieved. Safety of the pressure container under the dangerous pressure can be protected, the mechanism is sensitive and reliable in motion, and the mechanism is suitable for various pressure containers.
