Description
Technical field
The present invention relates to a kind of hydraulic control bypass valve type speed governing wipers, are used for pipeline cleaning operation.
Background technology
In carrying out pigging and detection process to oil-gas pipeline, the general laws and regulations requirement pigging equipment speed of service is 3.5~
5m/s；Pipeline detection equipment is in order to obtain preferable detection data quality, it is desirable that the speed of service of equipment is less than 5 m/s；Electricity
Magnetic ultrasonic detection equipment then requires its speed of service to be less than 2 m/s.Wiper by pipeline climb and fall section, bending section, hydrops,
Speed changes greatly when product sand and fouling section, and directly using conventional wiper, it is impossible to meet speed control requirements.
Existing oil-gas pipeline wiper speed control method is active control mode and passive control mode.
Active control uses by-passing valve control mode, and technical solution is：Wiper speed or use are acquired with mileage wheel
Acceleration transducer obtains wiper speed；Electric-control system is to signal processing；The opening degree of eduction valve is adjusted by motor；
Again by pressure difference before and after eduction valve aperture regulation wiper, wiper motive force is adjusted, to control the wiper speed of service.
Passive control mode is by adjusting the pressure medium and flow of arrival end and outlet end in pigging operation come indirectly
Control wiper speed.Because of the compressibility of gas, passive control mode is often difficult to reach preferable speed control effect, clearly
Pipe device was easy because of speed excessive the problems such as causing to impact, causing wiper and pipe damage.
Patent CN201410219086.7 discloses a kind of automatic speed regulation wiper, and the program is passed using half-crossed belt
Dynamic, complex working condition lower belt is easy sideslip and skidding in pipeline, and program speed acquisition wheel passes through spring tension and branch
Strut realizes that total arrangement length is longer, it is difficult to meet wiper and pass through tube bends means suitable.
Patent CN201410225525.5 discloses a kind of wiper speed acquisition device, and the program uses speed acquisition wheel
The mode for driving hydraulic pump, inner wall of the pipe is pressed on extension spring and strut by speed acquisition wheel.Therefore the program is applied
On wiper, wiper entire length can be relatively long, is unfavorable for device and passes through bend pipe.
Patent CN 201410708220.X disclose a kind of wiper speed control with hydraulic system, and the program will
Wiper speed is converted into the rotation of centroplasm gauge block by hydraulic system, and the centrifugal force that mass block rotation generates produces brake block
Raw extruding force.The program is complicated, and feasibility is relatively low.
Patent CN 201610134623.7 discloses a kind of rotary by-passing valve speed governing wiper, program speed acquisition
Wheel uses radial arrangement, is easy by branch pipe tee connection position stuck.
Patent CN 201610015859.9 discloses a kind of wiper hydraulic control brake gear, and the program passes through hydraulic system
Acquire the wiper speed of service, and the control resistance of bad student one and velocity correlation.Patent CN 201610013135.0 is disclosed
A kind of wiper brake gear, the program acquires the wiper speed of service using hydraulic system, and is rotated and generated by mass block
Control force.In above two scheme, brake block continues and pipe friction, and is used in series with conventional wiper device, increases
Complete equipment complexity.
Patent CN 201610013358.7 discloses a kind of bypass valve type speed governing wiper, and program speed acquisition wheel is set
It sets among wiper, the by-passing valve that slides axially is arranged on cylinder centre position, layout so that intermediate throttle valve is too small；Simultaneously
The speed acquisition wheel of radial arrangement is easy stuck at threeway position.
Current active control mode controls electrical consumption electric energy, and the included accumulator electric-quantity of wiper is limited, therefore long
It is restricted apart from pipeline cleaning.On the other hand, the by-passing valve control program of automatically controlled mode is because it is contemplated that pipe interior medium, pipeline shape
The factors such as shape and become complicated.State's internal bypass valve active control mode wiper is still immature, such external wiper is rented
With expensive, country's oil-gas pipeline pigging is still based on passive control mode at present.Therefore, develop applicable working condition it is wider from
Dynamic speed governing wiper is of great significance and prospect of the application.
