In the embodiment of the present invention, the first elastic member 302 and the second elastic member 307 used are both pressure springs.
The complete Christmas tree is composed of a lower valve body 1, a lower oil pipe 2, an upper oil pipe 3 and an upper valve body 4, a flank oil pipe connected in the upper valve body 4 is externally connected with an oil nozzle, in the process of oil conveying, oil passes through the lower valve body 1, the lower oil pipe 2, the upper oil pipe 3, the upper valve body 4 and the oil nozzle in sequence and is conveyed to a pipeline externally connected with the oil nozzle, wherein when the oil passes through the lower oil pipe 2, most of the oil flows into the upper oil pipe 3 from a middle channel of an annular plug 106, and a small part of the oil flows into the upper oil pipe 3 through a gap between the annular plug 106 and the lower oil pipe 2.
Another part of the oil flows upwards from the lower oil pipe 2 through the right through groove 3c of the upper oil pipe 3 and flows into the oil in the upper oil pipe 3 from the upper outlet of the right through groove 3c, the oil on the upper side in the right through groove 3c flows leftwards and flows into the upper oil pipe 3 and applies a leftward thrust to the positioning plate 303, the oil flows upwards to impact the auxiliary baffle 207 and applies an upward thrust to the auxiliary baffle 207, so that the auxiliary baffle 207 drives the shaft sleeve 206 to upwards turn around the axis of the second rotating shaft 205, the shaft sleeve 206 drives the tail plate 209 and the limiting rod 210 to downwards turn, the downward-turned limiting rod 210 pulls the auxiliary rope 311 and drives the main rope 310 to be straightened downwards, the thrust received by the auxiliary baffle 207 is transmitted to the positioning plate 303 through the auxiliary rope 311 and the main rope 310, and the positioning plate 303 transmits the thrust from the oil and the force from the auxiliary baffle 207 to the first elastic member 302 through the sliding rod 301, and the first elastic element 302 absorbs all forces applied to the positioning plate 303 to the left, so that after the auxiliary rope 311 is straightened, the auxiliary baffle plate 207 is restrained by the auxiliary rope 311 and is not turned upwards by the thrust of oil any more, and when the oil is kept in a stable conveying state in the upper oil pipe 3, the positioning plate 303 and the auxiliary baffle plate 207 are also kept in a stable state in the right through groove 3 c.
When the petroleum to be extracted passes through the lower valve body 1 and the lower oil pipe 2, if the pressure intensity changes in a certain area in the flowing petroleum are inconsistent, the gas in the area expands and contracts unstably in the petroleum, meanwhile, the inertia force of the petroleum in the rapid flowing process is larger than the viscous force of the petroleum, the petroleum is easily influenced by the change of the internal gas, finally, the area develops and forms irregular turbulence, at the moment, the gas expanding outwards in the petroleum drives the petroleum to generate wave-shaped fluid to impact the inner wall of the upper oil pipe 3, so that the flow rate of the petroleum flowing through the upper oil pipe 3 is increased instantaneously, the output quantity of a subsequent oil nozzle is increased temporarily and abnormally, at the moment, the unstable factors of the gas are released due to the increase of the flow rate of the petroleum on the left side of the right through groove 3c, the internal pressure intensity of the petroleum is reduced, and the petroleum on the upper side in the right through groove 3c is converged into the upper oil pipe 3 leftwards, the leftward pushing force applied to the positioning plate 303 is increased, so that the positioning plate 303 pushed leftward drives the first elastic member 302 to stretch leftward through the sliding rod 301, and simultaneously the positioning plate 303 moving leftward lowers the main rope 310 and the auxiliary rope 311, so that the auxiliary baffle 207 continues to turn upward under the pushing force of oil, and then when the pushing force of oil on the positioning plate 303 and the pushing force of oil on the auxiliary baffle 207 counter balance the stretching force of the first elastic member 302, the positioning plate 303 and the auxiliary baffle 207 stop moving, and at this time the auxiliary baffle 207 is turned upward in a horizontal state, oil is blocked by the auxiliary baffle 207 during passing through the annular plug 106, so as to reduce the amount of oil entering the upper oil pipe 3, until the flow area of oil leaves the upper oil pipe 3, the oil flow in the upper oil pipe 3 is stabilized, the pushing force of oil on the positioning plate 303 and the pushing force of oil on the auxiliary baffle 207 are reduced to stable values, and at the same time the stretched first elastic member 302 drives the positioning plate 303 and the auxiliary baffle 207 to move and reset, the realization carries out slight regulation and control to the unusual increment that the oil brought when producing the torrent, reduces the deviation that the oil produced when taking place the torrent, further improves the accuracy that the oil constant speed quantitative transportation, slows down the unstable situation of oil mass of the fuel sprayer output of production tree flank.
When the flow rate of the oil tree for conveying oil needs to be increased, under the condition that the oil extraction force of external oil extraction equipment for conveying oil is unchanged or enhanced, the output shaft of the driving motor 101 drives the driving bevel gear 102 to rotate, the driving bevel gear 102 is meshed with the driven bevel gear 104 to drive the screw rod 103 to rotate, the rotating screw rod 103 drives the sliding barrel 105 to move upwards along the left through groove 3a, the sliding barrel 105 drives the annular plug 106 to move upwards and approach the adjusting groove 3b of the upper oil pipe 3, the gap between the annular plug 106 and the lower oil pipe 2 is reduced, the proportion of oil flowing into the upper oil pipe 3 from the middle channel of the annular plug 106 is increased, the factor of unstable turbulence generated when the oil gathers is reduced, the main baffle plate 203 moves upwards along with the annular plug 106, and the static push block 309 pushes the main baffle plate 203 which moves upwards, the main baffle plate 203 and the first torsion spring 204 are driven to turn downwards around the first rotating shaft 202, as shown in fig. 10, the main baffle plate 203 is transversely arranged above the middle channel of the annular plug 106, the cross-sectional area of oil circulation is reduced under the condition that the oil extraction force of the oil extraction equipment to oil is unchanged or enhanced, the purpose of increasing the oil flow rate is achieved, meanwhile, the thrust of the oil flowing at high speed to the positioning plate 303 and the auxiliary baffle plate 207 is also increased, the first elastic part 302 needs to generate enough tensile force after being stretched leftwards to counterbalance the thrust of the positioning plate 303 and the auxiliary baffle plate 207, the first elastic part 302 drives the positioning plate 303 to move leftwards, the positioning plate 303 moving leftwards puts the main rope 310 and the auxiliary rope 311 downwards, meanwhile, the push block 309 pushes the main baffle plate 203 to drive the auxiliary baffle plate 207 to turn downwards, and the auxiliary baffle plate 207 drives the tail plate 209 and the limiting rod 210 to turn downwards, the distance of lowering the main rope 310 and the auxiliary rope 311 by the positioning plate 303 is complemented, the main rope 310 and the auxiliary rope 311 are still ensured to be kept in a straight state by adjusting the positions and states of the main baffle plate 203 and the auxiliary baffle plate 207 when the flow rate of oil is changed, so that high-sensitivity response matching is realized between the positioning plate 303 and the auxiliary baffle plate 207 when the later-stage oil generates a turbulent flow phenomenon, and the phenomenon that the normal conveying work of the oil is interfered because the auxiliary baffle plate 207 is touched by mistake when the flow rate of the oil is adjusted is avoided.
In addition, after the flow rate of the oil delivery by the Christmas tree is increased, the proportion of the oil flowing into the upper oil pipe 3 from the gap between the annular plug 106 and the lower oil pipe 2 is reduced, the proportion of the oil flowing into the upper oil pipe 3 from the middle channel of the annular plug 106 is increased, so that the factor of generating unstable channeling when the oil is gathered is reduced, and the oil stably passes between the lower oil pipe 2 and the upper oil pipe 3 at a high speed.
