将所需的零件按照图1连接。装上验收合格的剪切销，压力表指示0，加压至剪

Connect the required parts according to Figure 1. Install the qualified shear pin, the pressure gauge indicates 0, pressurize until the shear pin is cut, read the pressure value and record, release the pressure, and proceed to the next test. The safety valve is tested piece by piece, and the highest and lowest gears of each unit are tested once. After the test is completed, the inspector fills in the "Safety Valve Blowout Test Report" and archives it, and feeds back the test results to the production department and the shipping group. Shear pin test, 3~5 pieces are sampled for every 1000 pieces
