[0021] The water filling valve 1 is composed of a water filling valve hydraulic cylinder 1.1 and a water filling valve spool valve 1.2. The water filling valve spool valve 1.2 is controlled by the water filling valve hydraulic cylinder 1.1 to open and close the water filling valve 1. When the water filling valve 1 is opened, low pressure water enters the steel pipe 12 through the water filling pipe 9.1. The air exhausting valve 2 is composed of an air exhausting valve hydraulic cylinder 2.1 and an air exhausting valve spool valve 2.2. The air exhausting valve spool valve 2.2 is controlled by the air exhausting valve hydraulic cylinder 2.1 to open and close the air exhausting valve 2. When the air exhausting valve 2 is opened, the emulsion in the steel pipe 12 enters the water pool 13 through the pipe. The water pipe valve group 3 is composed of a check valve 3.1, a sealing ring unloading hydraulic cylinder 3.2, a sealing ring unloading spool valve 3.3, a pipe body unloading spool valve 3.4, a pipe body unloading hydraulic cylinder 3.5, a stop valve 3.6 and a stop valve hydraulic cylinder 3.7. The check valve 3.1 is used to prevent the high pressure water in the sealing high pressure water pipe 10.1 from flowing back to the booster. The sealing ring unloading spool valve 3.3 is controlled by the sealing ring unloading hydraulic cylinder 3.2 to unload the high pressure water in the sealing high pressure water pipe 10.1. The pipe body unloading spool valve 3.4 is controlled by the pipe body unloading hydraulic cylinder 3.5 to unload the high pressure water in the pipe body high pressure water pipe 10.2. The stop valve 3.6 is controlled by the stop valve hydraulic cylinder 3.7 to statically maintain the pressure of the high pressure water in the pipe body high pressure water pipe 10.2 when the pressure of the pipe body reaches the set value. The components of the water pipe valve group 3 are controlled by the hydraulic cylinders to pressurize, maintain and unload the pressure of the sealing and the pipe body. The emulsion enters the low pressure booster 4 and the high pressure booster 6 through the water pipe 9.2, and the pressure of the emulsion is increased by the oil balance. The water pipe 9.2 is controlled by the pneumatic ball valve 9.3. The low pressure booster 4 is a low pressure large flow booster, which is used when the pressure of the steel pipe is low. The high pressure booster 6 is a high pressure small flow booster, which is used when the pressure of the steel pipe is high. When the pressure of the steel pipe is high, the low pressure booster 4 is used first to reach a certain pressure, and then the high pressure booster 6 is used to reach the set pressure, which can effectively reduce the pressure increasing time and improve the pressure increasing efficiency without increasing the stroke of the booster. The low pressure booster valve group 5 is installed at the outlet of the low pressure booster 4, which is composed of check valves 5.1 and 5.2 and a safety valve 5.3. The check valves 5.1 and 5.2 are used to prevent the high pressure water from flowing back to the low pressure water pipe, and the safety valve 5.3 is used to discharge the high pressure water when the check valve 5.2 fails to work, thereby avoiding the impact on the low pressure booster 4.

The pressure detecting device 8 is installed on the water pipe valve group, which is composed of a sealing pressure detecting sensor 8.1, a sealing pressure gauge 8.2, a pipe body pressure detecting sensor 8.3 and a pipe body pressure gauge 8.4. The pressure gauges are used for direct observation of the pressure of the sealing and the pipe body, and the pressure sensors are used for real-time detection of the pressure in the sealing and the pipe body, thereby adjusting the pressure of the booster to make the pressure in the sealing and the pipe body reach the required value.
[0022] The working principle and use flow of the utility model: when starting work, the steel pipe 12 reaches the pressure test station. The pneumatic ball valve 9.3 is opened, and the emulsion enters the low-pressure intensifier 4 or high-pressure intensifier 6 through the water pipeline 9.2 for pressure boosting. The emulsion is sucked into the water cavity by the retraction of the intensifier hydraulic cylinder piston rod, and the emulsion is discharged by the extension of the intensifier hydraulic cylinder piston rod. According to the principle of oil balance, the pressure of the emulsion is multiplied. The high-pressure emulsion enters the water valve group 3, first passes through the one-way valve 3.1 and the sealed high-pressure water pipeline 10.1 to reach the sealing ring 11. The sealing ring 11 tightly holds the two ends of the steel pipe under the action of high-pressure water, so that the steel pipe does not move axially in the subsequent pressure change process. When the sealing pressure detection sensor 8.1 detects the set pressure of the sealing ring 11, the water filling valve cone valve 1.2 is opened, and the emulsion enters the inside of the steel pipe 12 through the pipeline, and the exhaust valve cone valve 2.2 is opened. The steel pipe 12 is filled with water while the gas in it is discharged, so that the inside of the steel pipe 12 is filled with water as much as possible. When the set time is reached, the exhaust valve cone valve 2.2 and the water filling valve cone valve 1.2 are closed, the stop valve 3.6 in the water valve group 3 reaches the passage state under the control of the stop valve hydraulic cylinder 3.7, and the high-pressure emulsion enters the inside of the steel pipe 12 through the pipe body high-pressure water pipeline 10.2. The intensifier continues to boost, the emulsion in the steel pipe 12 is extruded, the pressure rises rapidly, and the pipe body pressure detection sensor 8.3 detects that the set pressure is reached. The intensifier stops working to statically maintain the pressure of the emulsion in the steel pipe. After maintaining the pressure for a set time, the sealing ring unloading cone valve 3.3 and the pipe body unloading cone valve 3.4 in the water valve group 3 respectively unload the high-pressure emulsion in the steel pipe 12 and the sealing ring 11 under the action of the respective control hydraulic cylinders, the pressure rapidly decreases, and the whole test process is completed. The unloaded emulsion is finally discharged into the pool 13 through the pipeline. In the use of the intensifier, one intensifier can be used alone, or two intensifiers can be used together to control the pressure. The device has fast pressure boosting speed for the steel pipe, two intensifiers can reach high test pressure, the device runs stably, and there is no leakage.
