Description

Technical Field

[0001] The utility model relates to the technical field of safety valves, in particular to a safety valve with an adjustable drain outlet angle. Background Art

[0002] A safety valve is a type of valve body used to be installed on a pressure vessel or pipeline. When the pressure in the pressure vessel or pipeline exceeds the specified value, the safety valve can open and release the pressure through the pressure relief port to relieve the pressure of the pressure vessel or pipeline, thereby achieving the purpose of protecting the pressure vessel or pipeline. The angle of the pressure relief port on the safety valve currently on the market is fixed, so when the drain pipe is connected to the pressure relief port of the safety valve, it will be restricted by the angle of the pressure relief port of the safety valve, which will bring inconvenience to the connection between the drain pipe and the pressure relief port of the safety valve.

[0020] The first inclined surface 211 forms a 45-degree angle with the axis of the first connecting tube 21, and the second inclined surface 221 forms a 45-degree angle with the axis of the second connecting tube 22. By adopting this structure, when the second connecting tube rotates relative to the first connecting tube, when the axis of the second connecting tube coincides with the axis of the first connecting tube, the drain connector can be in a straight-through state, or when the axis of the second connecting tube is perpendicular to the axis of the first connecting tube, the drain connector can be in a bent-through state.
