Description
Technical field
The invention belongs to hydraulic fracturing equipment technical field, it is related to a kind of fluid power and remotely controls high pressure pipe joint.
Background technique
In hydraulic fracturing construction, passing through low-pressure manifold by fracturing blender truck is pressure break pump truck feed flow；After the pressurization of fracturing unit truck high-pressure pump
Fracturing fluid converge through outlet side in high pressure pipe joint；Fracturing fluid after converging enters well head by high pressure line, along pit shaft into
Enter stratum and carry out seam, stratum flow conductivity is transformed.Wherein, the regions such as fracturing unit truck, high pressure pipe joint, high pressure line belong to high pressure
Area, in order to repair pump truck, operator usually closes pump truck outlet side plug valve under high pressure, and there are larger personal injury wind for this
Danger.
Existing high pressure pipe joint mainly uses the opening and closing of manpower manual control high pressure cock valve door, and construction personnel needs
It opens the plug valve on high pressure pipe joint manually into higher-pressure region and realizes that the method for opening or closing cock has been difficult to realize, not only
Personal safety generation is seriously threatened, it is serious to violate HSE labour rules and regulations, the erroneous judgement of cock state in During manual operation

And the instruction of manifold control software is handled, it receives and is converted into electric signal transmission after instruction to electrodynamic pump and pressure distributor,
Electrodynamic pump and pressure distributor is promoted to work；Electrodynamic pump: it with electrically driven (operated) working barrel, is operated after reception control box signal, to liquid
Press distributor pumps hydraulic oil；Pressure distributor: after reception control box signal, the cock valve position to be opened is confirmed, by its phase
The hydraulic oil valve answered is opened, to control running of hydraulic power oil direction；Fluid power controls the hydraulic cylinder and piston in cock box: piston
The movement of formula, double-acting type hydraulic cylinder, piston both direction replaces oil inlet by two chambers, completes by the effect of hydraulic coupling；Tightly
Fixing bolt: it is used to fixed piston and crank link mechanism；Crank link mechanism: the reciprocating motion of piston is changed into the rotation of crankshaft
Transhipment is dynamic, while the power that will act on piston is changed into the torque that crankshaft externally exports, to drive cock to rotate；Cock: logical
Cock rotation is crossed to open and close to control plug valve；Cock instruction pin: instruction tap location；Proximity sensor: detection cock
It indicates the mobile message of pin, and is converted into electric signal and feeds back to control cabinet.
In some specific embodiments, piston and crank link mechanism are changed to hydraulic motor, hydraulic motor driving
Cock rotation.
Further, fluid power remotely control high pressure pipe joint working principle it is as follows:
1. operator controls software by tele-control system (measuring truck) manifold and instructs to assign plug valve ON/OFF；
2. control cabinet is processed to be converted to electric signal after receiving instruction, and is sent to electrodynamic pump；
3. electrodynamic pump operates after receiving electric signal, pumps hydraulic oil reaches pressure distributor；
4. pressure distributor opens the hydraulic fluid control valve door of target plug valve according to control cabinet signal, hydraulic oil passes through
Hydraulic line enters hydraulic cylinder: if opening plug valve, hydraulic oil enters from right side, left side discharge, if cut-out tap valve, liquid
Pressure oil enters from left side, right side discharge；
5. hydraulic oil drives hydraulic cylinder piston stretching/contraction in fluid power control cock box, piston and control cock rotation
Crank link mechanism between using fastening bolt connect, piston driving cock counterclockwise/rotate clockwise, plug valve is gradually opened
It opens/closes；
6. after instruction pin joint contacts proximity sensor, proximity sensor can send feedback signal to control cabinet computer, control
Case computer processed assigns instruction and stops electrodynamic pump and pressure distributor operating.
Or
1. operator controls software by tele-control system (measuring truck) manifold and instructs to assign plug valve ON/OFF；
2. control cabinet is processed to be converted to electric signal after receiving instruction, and is sent to electrodynamic pump；
3. electrodynamic pump operates after receiving electric signal, pumps hydraulic oil reaches pressure distributor；
4. pressure distributor opens the hydraulic fluid control valve door of target plug valve according to control cabinet signal, hydraulic oil passes through
Hydraulic line enters hydraulic motor, and hydraulic motor drive cock is counterclockwise/it rotates clockwise, plug valve gradually unlatching/closing；
5. after instruction pin joint contacts proximity sensor, proximity sensor can send feedback signal to control cabinet computer, control
Case computer processed assigns instruction and stops electrodynamic pump and pressure distributor operating.
Further, the mutual feedback relationship between high pressure pipe joint and pressure break pump truck is as follows.High pressure pipe joint and pressure break pump truck
Between using four core data lines connect.Influence each other between cock valve switching state and pump truck operating status: (1) pump truck is in fortune
It can not cut-out tap valve when row state；(2) pump truck can not start when plug valve is closed.
Further, manifold control software both can also can control cock and be opened with real-time display cock unlatching/closed state
It opens/closes, and multiple high-pressure manifold plug valves may be implemented and open or close, strong real-time, flexible operation.
Further, threeway uses Y-type three way type.
Currently, most high pressure pipe joints connect high pressure straight tube and plug valve, but the flowing resistance of T-type threeway fluid using T-type threeway
Power is big, and flow direction is difficult to determine.And the design is small using Y-type three way type connection high pressure straight tube and plug valve, fluid flow resistance,
A large amount of fluids are flowed to well head direction, are less prone to turbulent flow, are gushed resistance phenomenon.
Further, further include support frame and positioning pin, may be implemented to cover the upper of manifold more by support frame and positioning pin
Lower superposition and overall movement.
Pressure break provided by the invention remotely controls high pressure pipe joint with fluid power, can be to high pressure pipe joint locally control or long-range control
