Description

TECHNICAL FIELD

[0001] The present application belongs to the field of mechanical production and processing, in particular to a safety valve drilling device. BACKGROUND

[0002] Safety valves are generally used on pressure vessels, and when the pressure in the vessel exceeds the safe pressure of the vessel, the safety valve automatically opens, so that the pressure vessel will not explode due to overpressure, and the safety valve plays an important protective role for personal safety and equipment operation.

[0003] A patent application with publication number CN102814531A discloses a safety valve drilling tool, which comprises a safety valve, an equilateral angle iron, a positioning bolt, and an adjusting bolt. The equilateral angle iron is provided with a positioning through hole and a threaded through hole. The positioning bolt passes through the positioning through hole and is screwed into the threaded hole of the safety valve. The adjusting bolt is screwed into the threaded through hole of the equilateral angle iron. The safety valve is fixed on the equilateral angle iron by the positioning bolt, and the angle of the safety valve is adjusted by rotating the adjusting bolt, so that the drilling plane of the safety valve is perpendicular to the axial direction of the drilling tool. The adjusting bolt is used in cooperation with the drilling sleeve to accurately guide the drilling tool to the drilling position. The positioning bolt can effectively ensure that the safety valve is firmly locked on the equilateral angle iron, and the stability during drilling is high. The drilling tool cooperates with the drilling sleeve to overcome the poor accuracy during inner hole processing.
