Description
Technical field
The invention belongs to field of petroleum exploitation, and in particular, to a kind of anti-recoil valve of new type of safe for having both cutoff function.
Background technology
With increasingly exhausted, the marine petroleum development cause rapid development of On shore Oil Development, modern marine oil exploration
The range of exploitation is gradually marched from coastal waters, shallow sea to off-lying sea, blue water.With the increasingly increase of operating water depth, face
Environment also become increasingly complex, considerably increase sea oil drilling and production exploitation difficulty.In, the marine site of deep-sea, marine drilling is put down
Platform is under the action of wave, other than front and rear wave, also generates heave movement, this with heave above and below wave period
Movement influences the decentralization of underwater equipment production tree, preventer and installation process very big.Therefore, it is necessary to pacify on drilling platforms
Guide line tensioner system is filled, guide line tensioner is that underwater equipment production tree, preventer decentralization and peace turn are most important in the process
Safety curtain, once it breaks down, it will bring massive losses.Guide line tensioner system mainly includes：Control skid,
Pressure vessel, accumulator, tensioner body, leading block, idle pulley and steel wire rope composition.Pressure vessel is collectively constituted with accumulator
Gas-liquid spring compensates the platform caused by wave heave movement and heaves displacement.Underwater equipment is being transferred and installed to guide rope
Simultaneously as complicated ocean environmental load acts on production tree, on preventer, cause the load that steel wire rope is born unstable, it is long
In the decentralization and installation process of time, the steel wire rope of guide line tensioner can be broken suddenly, since steel wire rope is in before fracturing
Tensioning state, the interior a large amount of potential energy of accumulation of steel wire rope, suddenly after fracture, the potential energy being stored in steel wire rope can turn rapidly steel wire rope
The kinetic energy of steel wire rope is turned to, steel wire rope is caused to accelerate recoil upwards, the steel wire rope of recoil can influence on drilling platforms equipment just
Often operation threatens the life security of staff on platform.Therefore steel wire rope recoils in order to prevent, can be in tensioner body with storing
The anti-recoil valve of safety can be connected between device, its essence is exactly an electric throttle valve for having both cutoff function, when detecting steel
For cord suddenly after fracture, control system transmits a signal to the anti-recoil valve of safety, and the anti-recoil valve of safety acts rapidly, is reduced rapidly stream
Body flow area weakens the recoil of steel wire rope up to completely closing flow channel.
At present, well known safety anti-recoil valve construction be by drive system, vertical direction liquid in-out valve body, sleeve spool valve,
Sealing element forms.Drive system drives the inner cylinder rotating of turnbarrel spool by output device, due to having on inside and outside sleeve
The through flow hole of same diameter in inner cylinder rotary course, can change the opposite flow area in hole on inside and outside sleeve, so as to fulfill section
Flow function.When there is situation that steel wire rope is broken suddenly, control system can transmit signal to the anti-recoil valve of safety, safe counnter attack
It rushes valve to act rapidly, drive system rotation drives inner sleeve rotation so that the opposite passage section of inside and outside sleeve is gradually reduced, and is led to
The flow for crossing valve body is gradually reduced, until the trepanning on inside and outside sleeve is staggered completely, is turned off fluid passage, is realized cutoff function.
But the existing anti-recoil valve of safety, in the case of Fluid pressure is big, flow velocity is high, fluid is big to the impact force of inner sleeve, makes
The frictional resistance for obtaining inside and outside sleeve becomes larger, and inner sleeve rotation is difficult, and flow-rate adjustment precision is low, instability of flow, it is impossible to realize nothing
Pole is adjusted, and for requiring for abnormal strictly guide line tensioner, this obviously cannot meet the normal operation of equipment, easily send out
Raw safety accident.Therefore, develop a set of high-precision, high sensitivity, high stability, can the anti-recoil valve of safety of electrodeless adjustment seem
It is particularly important.

Relative to the prior art, beneficial effects of the present invention are as follows：1. servo motor is run, and then passes through shaft coupling band
Dynamic leading screw rotation, the rotation of leading screw drive the connecting shaft being located on leading screw to be axially moved, and then drive drive link by connecting seat
Axial operation, then axially run by connect band movable valve plug, so as to adjusting grooves and the position in valve body, when groove and valve
When body fluid recirculation hole is aligned completely, maximum is led to by the valve body liquid stream of valve body liquid stream through-hole, when the two is staggered completely, flow is
Zero, the flow of valve body liquid is adjusted by this way；2. ball screw system has micro and high speed feed performance characteristics, watching
It takes after motor driver provides corresponding signal, servo motor driving ball-screw pushes spool accurately and fast to act, and realizes high-precision
Degree, high sensitivity, electrodeless flow-rate adjustment；3. since servo motor has brake function, it can be achieved that ball-screw self-locking so that whole
A transmission system and spool can be always maintained in the original location after servo motor stops operating, will not be because of the excessive promotion valve of pressure
High stability flow-rate adjustment is realized in core counter motion.
