Description
Technical field
The present invention relates to a kind of bypass valve type speed governing wiper.
Background technology
Carrying out in pigging and testing process to oil and gas pipes, the general laws and regulations requirement pigging equipment speed of service is 3.5 ~ 5m/s; Pipeline detection equipment preferably detects the quality of data to obtain, and requires that the speed of service of equipment is lower than 5m/s; Electromagnetic acoustic checkout equipment then requires that its speed of service is lower than 2m/s.Wiper, being changed greatly by pipeline climb and fall section, bending section, hydrops, long-pending sand and fouling section hourly velocity, directly uses conventional wiper can not meet speeds control requirement.
Existing oil and gas pipes wiper speed control method is ACTIVE CONTROL mode and Passive Control mode.
ACTIVE CONTROL adopts by-passing valve control mode, and its technical scheme is: gather wiper speed with mileage wheel or obtain wiper speed with acceleration transducer; Electric-control system is to signal transacting; The opening degree of eduction valve is adjusted by motor; Regulate pressure reduction before and after wiper by eduction valve aperture again, adjustment wiper motive force, thus control the wiper speed of service.
Passive Control mode is that the pressure medium and flow by regulating arrival end and the port of export in pigging operation controls wiper speed indirectly.Because the compressibility of gas, Passive Control mode is often difficult to reach better speeds control effect, and wiper easily causes impact because speed is excessive, causes the problem such as wiper and pipe damage.
