Hydraulic oil in two circulation exchange oil cylinders 4 is because to-and-fro motion causes damage, in two circulation exchange oil cylinders 4, can form vacuum, when the pressure of degree of vacuum generation reaches the pressure of the 4th one-way valve 106 or the 5th one-way valve 111 settings, the 4th one-way valve 106 or the 5th one-way valve 111 are opened, and the hydraulic oil in exchange liquid fuel tank 117 will cover in two circulation exchange oil cylinders 4 automatically.
When the pressure in pipeline surpasses the pressure of the first relief valve 105, the second relief valve 110 or the 3rd relief valve 101, the first relief valve 105, the second relief valve 110 or the 3rd relief valve 101 are opened, and hydraulic oil is flowed in exchange liquid fuel tank 117.
During pressure in need to measuring certain section of pipeline, the stop valve (the first stop valve 24, the first stop valve 26, the 4th stop valve 107, the 6th stop valve the 112, the 11 stop valve 102) that only pressure gauge connecting with corresponding pipeline (the first pressure gauge 25, the second pressure gauge 27, the 3rd pressure gauge 108, the 4th pressure gauge 113, the 5th pressure gauge 103) below need to be arranged be opened and can read the force value in pipeline by pressure gauge.
When needs clean oil delivery pipeline 7, close the 7th stop valve 51 and the tenth stop valve 56, open the 8th stop valve 52 and the 9th stop valve 55, the power oil of bringing from two circulation exchange oil cylinders defeated 4, directly from the filler opening of the first one-way valve 115, enter (due to the one end near crude oil, also be provided with the 8th one-way valve 116, so power oil can only enter from the filler opening of the first one-way valve 15), by the 3rd one-way valve 114, enter storage tank 8 again, realize the cleaning to oil delivery pipeline 7.Start heater 10, to merging the liquid of discharging from exchange oil cylinder, heat, oil delivery pipeline is carried out to heat and clean.
