The oil is conveyed to a pipeline externally connected with the oil nozzle sequentially 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 the oil conveying process, wherein most of the oil flows into the upper oil pipe 3 from a middle channel of the annular plug 106 when the oil passes through the lower oil pipe 2, 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.
And a part of oil flows upwards from the lower oil pipe 2 through the right through groove 3c of the upper oil pipe 3, and is gathered into the oil of the upper oil pipe 3 from the upper outlet of the right through groove 3c, the oil at the upper side in the right through groove 3c is gathered into the upper oil pipe 3 leftwards, meanwhile, the oil upwards flows to impinge on the auxiliary baffle 207, meanwhile, the auxiliary baffle 207 is upwards pushed, the shaft sleeve 206 is driven by the auxiliary baffle 207 to upwards overturn around the shaft center of the second rotating shaft 205, the tail plate 209 and the limiting rod 210 are driven by the shaft sleeve 206 to downwards overturn, meanwhile, the auxiliary rope 311 is pulled by the downwards overturned limiting rod 210, the main rope 310 is driven to downwards straighten, meanwhile, the thrust received by the auxiliary baffle 207 is transmitted to the locating plate 303 through the auxiliary rope 311 and the main rope 310, meanwhile, the thrust from the oil is transmitted to the first elastic piece 302 through the sliding rod 301, and all the forces received by the locating plate 303 leftwards are absorbed by the first elastic piece 302, after the auxiliary rope 311 is straightened, the auxiliary rope 311 is kept in a stable state in the upper oil pipe 3, and the state of the oil is kept in the stable state of the upper oil pipe 3.
When the extracted petroleum passes through the lower valve body 1 and the lower oil pipe 2, if the pressure change of a certain area inside the flowing petroleum is inconsistent, the gas in the area expands and contracts unstably in the petroleum, meanwhile, the inertia force of the petroleum in the rapid flowing petroleum is larger than the viscous force of the petroleum, the petroleum is easily influenced by the internal gas change, finally, the area develops to form irregular turbulence, at the moment, the gas in the outward expanding petroleum drives the petroleum to generate wavy fluid to impact the inner wall of the upper oil pipe 3, the flow velocity of the petroleum flowing through the upper oil pipe 3 is instantaneously increased, the output of a subsequent oil nozzle is caused to have a short abnormal increment, at the moment, the petroleum at the left side of the right through groove 3c is released due to the increase of the flow velocity, the internal pressure of the petroleum is reduced, the petroleum at the same time, the petroleum at the upper side in the right through groove 3c is converged to the left before entering the upper oil pipe 3, the left thrust force applied to the locating plate 303 is also increased, so that the locating plate 303 pushed to the left drives the first elastic piece 302 to stretch to the left through the sliding rod 301, meanwhile, the locating plate 303 moving to the left lowers the main rope 310 and the auxiliary rope 311, so that the auxiliary baffle 207 continues to turn upwards under the thrust force of the oil, then when the thrust force of the oil to the locating plate 303 and the thrust force of the oil to the auxiliary baffle 207 are balanced with the stretching force of the first elastic piece 302, the locating plate 303 and the auxiliary baffle 207 stop moving, at the moment, the auxiliary baffle 207 turns upwards to be in a transverse state, the oil is blocked by the auxiliary baffle 207 in the process of passing through the annular plug 106, the amount of entering the upper oil pipe 3 is reduced, until after the turbulent flow area of the oil leaves the upper oil pipe 3, the oil flow in the upper oil pipe 3 is restored to be stable, the thrust force of the oil to the locating plate 303 and the thrust force of the oil to the auxiliary baffle 207 are greatly reduced to stable values, meanwhile, the stretched first elastic piece 302 drives the positioning plate 303 and the auxiliary baffle 207 to move and reset, so that the abnormal increment brought by the turbulent flow of petroleum is finely regulated and controlled, the deviation of the turbulent flow of the petroleum is reduced, the accuracy of constant-speed and quantitative conveying of the petroleum is further improved, and the unstable petroleum quantity output by the oil nozzle of the side wing of the christmas tree is slowed down.
When the flow rate of the christmas tree on petroleum delivery needs to be increased, under the condition that the pumping force of external christmas equipment on petroleum is unchanged or the pumping force is enhanced, the output shaft of a driving motor 101 drives a driving bevel gear 102 to rotate, the driving bevel gear 102 is meshed with a driven bevel gear 104 to drive a screw rod 103 to rotate, the rotating screw rod 103 drives a sliding cylinder 105 to move upwards along a left through groove 3a, the sliding cylinder 105 drives an annular plug 106 to move upwards and close to an adjusting groove 3b of an upper oil pipe 3, the gap between the annular plug 106 and a lower oil pipe 2 is reduced, the proportion of petroleum 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 petroleum flowing into the upper oil pipe 3 from a middle channel of the annular plug 106 is increased, the factor of unstable turbulence generated when petroleum is converged is reduced, and a main baffle 203 moves upwards along with the annular plug 106, the stationary pushing block 309 pushes the main baffle 203 moving upwards to drive the main baffle 203 and the first torsion spring 204 to turn downwards around the first rotating shaft 202, as shown in fig. 10, the main baffle 203 is horizontally arranged above the middle channel of the annular plug 106, the purpose of reducing the cross-sectional area of petroleum circulation under the condition that the petroleum extraction force of petroleum extraction equipment is unchanged or enhanced is achieved, the purpose of increasing the petroleum flow rate is achieved, meanwhile, the thrust of the petroleum flowing at high speed to the locating plate 303 and the auxiliary baffle 207 is also increased, the first elastic piece 302 needs to generate enough stretching force after being stretched leftwards to counter the thrust acted by the locating plate 303 and the auxiliary baffle 207, the first elastic piece 302 drives the locating plate 303 to move leftwards while the locating plate 303 moves leftwards to lower the main rope 310 and the auxiliary rope 311, meanwhile, the pushing block 309 pushes the main baffle 203 to turn downwards, the distance that the auxiliary baffle 207 drives the tail plate 209 and the limiting rod 210 to overturn downwards is complemented with the distance that the positioning plate 303 lowers the main rope 310 and the auxiliary rope 311, so that when the flow rate of petroleum is changed by adjusting the positions and states of the main baffle 203 and the auxiliary baffle 207, the main rope 310 and the auxiliary rope 311 between the limiting rod 210 and the positioning plate 303 can still be kept in a straightened state, when the turbulence phenomenon is generated in later petroleum, the positioning plate 303 and the auxiliary baffle 207 have high-sensitivity response coordination, and the phenomenon that the auxiliary baffle 207 is touched by mistake when the flow rate of petroleum is adjusted, and normal conveying work of petroleum is disturbed is avoided.
In addition, after the flow rate of the oil 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, and 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 of the oil when converging is reduced, and the oil passes between the lower oil pipe 2 and the upper oil pipe 3 at a high speed and stably.
