Description

Technical Field

[0001] The utility model relates to the technical field of valve pressure relief safety devices, in particular to a safe, convenient and adjustable safety device. Background Art

[0002] The sealing of traditional floating ball valves mainly relies on the action of the medium through the ball to achieve compression sealing on the sealing ring behind the ball. When the ball valve is closed, the sealing ring of the traditional structure separates the inlet end and the body cavity of the ball valve into two independent parts. The medium in the body cavity is more easily affected by the ambient temperature and pressure due to its small volume, which causes the pressure inside the body cavity to increase. If the pressure cannot be released, the sealing ring and even the entire ball valve device will be damaged.
