Embodiment 1
[0022] A dynamic detection process of a control valve of oil drilling equipment under high and low temperature conditions, including a. installing the detected part 3 on the detection device, and then connecting the detected part 3 with a pressurizing device; b. opening the detection device The heater 6 is used to heat the air temperature in the inner chamber of the tested part 3 to a rated high temperature of 60°C or use the ambient low temperature box 2 to lower the temperature to a rated low temperature of -18°C, and use the computer control system to maintain the temperature at the rated temperature value; c. Turn on the pressurizing device to pressurize the tested part 3 to the rated pressure of 1MPa; d. Repeatedly open 20 times under the rated pressure state through the valve stem 4 connected to the tested part 3; e. Stabilize the pressure for 0.5 hours, Collect the temperature and pressure values of the tested part 3, and compare the collected temperature and pressure ...
Embodiment 2
[0025] A dynamic detection process for control valves of oil drilling equipment under high and low temperature conditions, including a. installing the detected part on the detection device, and then connecting the detected part with the air compressor unit; b. turning on the heating of the detection device Heating the air temperature of the inner chamber of the tested part to the rated high temperature of 121°C or using the ambient low temperature box to reduce the temperature to the rated low temperature of -60°C, and using the computer control system to keep the temperature at the rated temperature value; c. Turn on the air compression The unit pressurizes the tested part to the rated pressure of 140MPa; d. Repeatedly open 30 times under the rated pressure state through the valve stem connected to the tested part; e. Stabilize the pressure for 2 hours and collect the temperature and pressure of the tested part Compare the collected temperature and pressure values with the r...
