[0002] Oil pipe valves are valves used to control the flow of oil in oil pipelines. Traditional oil pipe valves have a simple structure and are mainly divided into regulating valves, switching valves, one-way valves and pressure relief valves. Regulating valves mainly adjust the size of the flow hole by controlling the valve core. Switching valves are mainly divided into ball valves and gate valves. Neither regulating valves nor switching valves have the function of selecting the fluid flow path to buffer fast-flowing fluids. Summary of the invention

[0003] In order to improve the deficiencies of the prior art, the present invention provides an oil pipe valve that can block the through hole in the middle of the pipe through which fluid flows and the multiple spiral grooves arranged on the inner wall, select the fluid flow path, and buffer the fast-flowing fluid.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A oil pipe valve comprises an adjusting tube with a plurality of spiral grooves processed on the inner wall, expansion tubes are symmetrically arranged at both ends of the adjusting tube, a connecting tube is fixedly connected to each expansion tube, an end plate is rotatably connected to each expansion tube, a guide tube is fixedly connected to each end plate, a threaded tube is threadedly connected to each guide tube, a spacer is fixedly connected to each threaded tube, a spiral plate coupled to some of the spiral grooves in the plurality of spiral grooves is fixedly connected to each spacer, a reciprocating tube is slidably connected to each threaded tube, a sealing plate is fixedly connected to the side of each reciprocating tube close to the adjusting tube, an extension frame is fixedly connected to each end plate, and a cylinder for driving the corresponding reciprocating tube to slide is fixedly connected to each extension frame.

[0006] Furthermore, the number of the spiral plates provided on each of the spacers is half the number of the plurality of spiral grooves.

[0007] Furthermore, the distance between two ends of the spiral plate is greater than half of the distance between two ends of the spiral groove.

[0008] Furthermore, the end of each threaded tube is rotatably connected to an adjusting frame, and each extension frame is rotatably connected to two screw rods that drive the corresponding adjusting frame to slide through a screw.

[0009] Furthermore, a gear ring is fixedly connected to each of the end plates, and a side wheel for driving the corresponding gear ring to rotate is rotatably connected to the outer wall of each expansion tube.

[0010] The beneficial effects of the oil pipe valve of the present invention are as follows: it can block the through hole in the middle of the pipe fitting through which fluid flows and the multiple spiral grooves arranged on the inner wall, select the fluid flow path, and buffer the fast-flowing fluid; it can also fully seal the fluid flow path inside the pipe fitting to close the valve; it can also clean the spiral groove through the coupling of the spiral plate and the spiral groove to prevent the accumulation of impurities.

DETAILED DESCRIPTION

[0022] refer to Figure 1 , 2 , 3, 4, 5 and 6, detailed description of the embodiments of adjusting the fluid flow area of ​​the oil pipe valve:

[0023] A pipe valve, comprising a regulating pipe 11 with a plurality of spiral grooves 12 processed on the inner wall, a hollow portion formed in the middle of the regulating pipe 11, expansion pipes 13 symmetrically arranged at both ends of the regulating pipe 11, two expansion pipes 13 fixedly connected to both sides of the regulating pipe 11, each expansion pipe 13 fixedly connected to a connecting pipe 14, the two connecting pipes 14 are used for connecting the oil pipe, each expansion pipe 13 is rotatably connected to an end plate 15, a rotating sealing ring is arranged between the end plate 15 and the expansion pipe 13 to prevent leakage of fluid when the end plate 15 rotates, causing environmental pollution, each end plate 15 is fixedly connected to a guide pipe 17, the guide pipe 17 plays a role of spiral guide, each guide pipe 17 is threadedly connected to a threaded pipe 31, when the thread When the tube 31 moves along the axis, the threaded tube 31 performs a spiral motion under the guidance of the guide tube 17, and each threaded tube 31 is fixedly connected to a spacer frame 32, and each spacer frame 32 is fixedly connected to a spiral plate 33 coupled to some of the spiral grooves 12 in the plurality of spiral grooves 12, so that when the threaded tube 31 moves, the spacer frame 32 is driven to perform a spiral motion, and the spacer frame 32 drives the plurality of spiral plates 33 to screw into the corresponding plurality of spiral grooves 12, thereby blocking the plurality of spiral grooves 12, so that the fluid cannot flow from the plurality of spiral grooves 12, and further, the fluid can only flow from the through hole in the middle of the regulating tube 11, thereby realizing the area of ​​the fluid flow in the regulating tube 11, and at the same time, when the plurality of spiral grooves 12 allow the fluid to flow, the fluid flows through the plurality of The spiral groove 12 can buffer the flowing fluid to prevent the rapid flow of the fluid from impacting the parts. A reciprocating tube 22 is slidably connected to each threaded tube 31. A sealing plate 23 is fixedly connected to the side of each reciprocating tube 22 close to the regulating tube 11. An extension frame 18 is fixedly connected to each end plate 15. A cylinder 21 that drives the corresponding reciprocating tube 22 to slide is fixedly connected to each extension frame 18. The cylinder 21 is started, and the cylinder rod of the cylinder 21 drives the reciprocating tube 22 to slide. The sliding of the reciprocating tube 22 drives the sealing plate 23 to slide. After the sealing plate 23 slides, the middle part of the regulating tube 11 can be sealed. Therefore, when adjusting the flow area of ​​the fluid, the two sealing plates 23 on both sides can be selected to block the middle part of the regulating tube 11 to allow the fluid to flow from more The spiral grooves 12 can flow through, and the spiral plates 33 can be used to block the spiral grooves 12 to allow the fluid to flow from the middle of the regulating tube 11, so as to select the fluid flow path in the valve. When the valve needs to be closed, the spiral plates 33 are driven to block the spiral grooves 12. At the same time, the two sealing plates 23 are close to each other to block the middle of the regulating tube 11, thereby blocking the fluid flow path in the regulating tube 11 to prevent the fluid from continuing to flow. In the process of the spiral plates 33 blocking the spiral grooves 12, the impurities hanging on the spiral grooves 12 can be cleared, and the impurities in the middle of the regulating tube 11 can be scraped off in the process of the two sealing plates 23 sliding, so as to ensure the stable transportation of the transported fluid.

[0024] refer to Figure 6 , 7and 8, detailing an embodiment of ensuring blocking of multiple spiral grooves 12:

[0025] The number of spiral plates 33 arranged on each of the spacer frames 32 is half the number of the multiple spiral grooves 12. Therefore, the multiple spiral plates 33 on both sides are staggered and, after being screwed into the multiple spiral grooves 12 at the same time, the multiple spiral plates 33 completely block the multiple spiral grooves 12 to prevent the fluid from continuing to flow through the multiple spiral grooves 12.

[0026] refer to Figure 7 and 8 , an embodiment in which a plurality of spiral plates 33 cooperate with two sealing plates 23 to seal the regulating pipe 11 is described in detail:

[0027] The distance between the two ends of the spiral plate 33 is greater than half of the distance between the two ends of the spiral groove 12. Therefore, when the two spacer frames 32 are attached to the two ends of the regulating tube 11, the multiple spiral plates 33 on both sides overlap in the radial direction. When the two sealing plates 23 slide to fit each other and overlap with the regulating tube 11 and the multiple spiral plates 33, the path for the fluid flow in the regulating tube 11 can be completely blocked, thereby achieving the closure of the valve.

[0028] refer to Figure 8 , the embodiment of driving the two threaded tubes 31 to move is described in detail:

[0029] The end of each threaded tube 31 is rotatably connected to an adjusting frame 34, and each extension frame 18 is rotatably connected to two screw rods 41 that drive the corresponding adjusting frame 34 to slide through a screw drive, and each screw rod 41 is fixedly connected to the output shaft of the corresponding reduction motor I, and each reduction motor I is fixedly connected to the corresponding extension frame 18. The reduction motor I is started, and each reduction motor I drives the corresponding screw rod 41 to rotate. The screw rod 41 drives the corresponding adjusting frame 34 to slide through a screw thread, and the adjusting frame 34 drives the threaded tube 31 to move, thereby realizing the spiral movement of the threaded tube 31, and then realizing that multiple spiral plates 33 are coupled into multiple spiral grooves 12 or screwed out of multiple spiral grooves 12.

[0030] refer to Fig. 9 , an embodiment of driving the two end plates 15 to rotate is described in detail:

[0031] A gear ring 16 is fixedly connected to each of the end plates 15, and a side wheel 42 is rotatably connected to the outer wall of each expansion tube 13 for driving the corresponding gear ring 16 to rotate. Each side wheel 42 is fixedly connected to the output shaft of the corresponding reduction motor II, and each reduction motor II is fixedly connected to the corresponding expansion tube 13. When the reduction motor II is started, the reduction motor II drives the corresponding side wheel 42 to rotate. Each side wheel 42 meshes and drives the corresponding gear ring 16 to rotate, thereby driving the end plate 15 to rotate, realizing the rotation of the threaded tube 31, and then realizing the position adjustment of the spacer frame 32 and the multiple spiral plates 33, and then realizing the multiple spiral plates 33 to be screwed into different spiral grooves 12, so as to realize the cleaning of the multiple spiral grooves 12.

[0032] refer to Figure 6 , an embodiment of sealing the regulating tube 11 when the two sealing plates 23 are close to each other is described in detail:

[0033] The rubber sleeves 24 are fixedly connected to the corresponding end surfaces of the two sealing plates 23, so that when the two sealing plates 23 are pressed close to each other, the two corresponding rubber sleeves 24 are pressed, and the middle of the regulating tube 11 is sealed by the deformation of the rubber sleeves 24. The outer wall of the sealing plate 23 fits the inner wall of the regulating tube 11. Thus, the sealing effect of the two sealing plates 23 on the middle of the regulating tube 11 is ensured.

[0034] refer to Figure 6 , detailed description of the embodiment of preventing fluid leakage:

[0035] The inner walls of the reciprocating tube 22 and the threaded tube 31 are provided with sliding sealing sleeves, so as to prevent leakage of fluid and environmental pollution during the sliding process of the reciprocating tube 22 .

[0036] refer to Figure 7 and 8 , an embodiment in which a plurality of spiral plates 33 are screwed into a plurality of spiral grooves 12 is described in detail:

[0037] Each of the guide tubes 17 guides the threaded tube 31 in a spiral manner, and the spiral stroke of each threaded tube 31 is equal to the spiral stroke of the spiral groove 12. Therefore, under the guidance of the guide tube 17 on the threaded tube 31, the spiral plate 33 can be stably screwed into the spiral groove 12 to achieve the adjustment of the fluid flow area in the valve.

[0038] refer to Figure 6 and 8 , an embodiment of the spiral plate 33 and the sealing plate 23 sealing the regulating pipe 11 is described in detail:

[0039] A rubber pad is provided on the spiral surface of each spiral plate 33 close to the axis of the regulating tube 11, so that when the spiral plates 33 on both sides overlap, the two sealing plates 23 approach each other and when multiple spiral plates 33 overlap, the regulating tube 11 is sealed by the contact between the rubber pad and the extruded rubber sleeve 24.
