Description

Technical Field

[0001] The utility model relates to the technical field of safety valves, and more specifically, to a safety valve structure which is easy to install. Background Art

[0002] The safety valve is an automatic pressure relief protection device opened by the inlet static pressure. It is one of the most important safety accessories for pressure vessels. Its function is: when the pressure in the container exceeds a certain value, the valve is automatically opened by the pressure of the medium itself to quickly discharge a certain amount of medium. When the pressure in the container drops to the allowable value, the valve automatically closes again, so that the pressure in the container is always lower than the upper limit of the allowable pressure, automatically preventing accidents that may occur due to overpressure, so the bellows safety valve is also called the ultimate protection device for pressure vessels. When the pressure in the equipment and pipeline exceeds the allowable value, the valve automatically opens and then discharges the full amount; when the pressure drops to the specified value, the valve automatically closes to ensure the safe operation of the equipment.

[0003] Most existing safety valves are fixed with flanges, and are fixed with bolts during installation. When installing or disassembling, the bolts need to be turned separately, which is time-consuming and laborious. In this regard, we propose a safety valve structure that is easy to install.
