Description

Technical Field

[0001] The invention relates to the technical field of high-pressure manifolds, in particular to a double-discharge high-pressure manifold for fracturing. Background Art

[0002] The dual-discharge high-pressure manifold is an important equipment used in industrial applications such as fracturing operations. It is mainly made of high-strength alloy materials to withstand the huge pressure brought by high-pressure fluids. Its structure is usually complex, including multiple branch pipes, valves, connectors and seals. The dual-discharge design means that it can deliver high-pressure fluids in two directions at the same time, which greatly improves work efficiency. When working, the high-pressure manifold can accurately distribute and control the flow direction and flow rate of the fluid to ensure the smooth progress of the fracturing operation.

[0003] The existing high-pressure manifold used for fracturing is composed of branch pipes with different radii. Due to the different pressure requirements for conveying different high-pressure fluids, when a high-pressure fluid is transmitted at a specific pressure, the radii of different pipes will change the pressure of the fluid. A larger pipe radius will cause a loss of fluid pressure, which may affect the fracturing effect. A smaller pipe radius may cause excessive force on the pipe and cause it to rupture.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention sets a spatial mechanism. When the fracturing fluid passes through the high-pressure manifold, the radius of the pipeline will affect the pressure flowing in the pipeline. For flows requiring different pressures, the size of the suitable pipeline will also change accordingly. After the fracturing fluid enters the spatial shell, the hydraulic device will drive the telescopic rod to move inward, thereby driving the semi-arc plates to move inward. At the same time, due to the proximity of the four semi-arc plates, the inner plate between the two semi-arc plates will also slide along the inner wall of one of the semi-arc plates, thereby controlling the size of the pipeline radius, avoiding the loss of fluid pressure caused by a larger pipeline radius, and the possibility that a smaller pipeline radius may cause excessive force on the pipeline and cause it to rupture.

[0018] 2. The present invention sets a spatial mechanism. When the fluid flows into and out of the spatial shell, a fault will be formed due to the difference in the radius of the inflow and outflow pipes and the radius of the pipes in the spatial shell, which will cause a large pressure loss in the flow. By setting a conical surface 1 and a conical surface 2 in the connecting pipes 1 and 2 on both sides and using a conical transition section, the fluid can flow more smoothly and reduce some pressure losses. After passing through the conical surface 1, the fluid will enter the semi-arc plate through the deformable tough sleeve, so that the entire process will not produce an interface and fault perpendicular to the flow direction.

[0019] 3. The present invention sets a three-way mechanism. After the fluid enters the three-way pipe, the fluid will move to the two sides of the three-way pipe along the tough plate, thereby avoiding the pressure loss caused by the fluid directly impacting the inner wall of the three-way pipe. Due to the support of the tough plate by the support plate 2 and the telescopic spring pair, the tough plate will be deformed after being impacted by the fluid. The greater the pressure of the fluid and the faster the flow rate, the greater the impact force of the telescopic spring 1 and the tough plate, thereby making the bending arc of the tough plate larger and more convenient for the circulation of the fluid.

[0020] 4. The present invention sets a valve body mechanism and controls the rotation of the rotary handle to drive the threaded rod and the baffle to move upward, so that the fluid can pass through. When the fluid passes through the lower plate mechanism, the telescopic rod 2 will drive the four layers of the progressive plate to move different distances. At the same time, the inner arc plate in the progressive plate will also be pulled out, so that the lower half plate forms a gradient shape, avoiding the lower half plate directly causing pressure loss to the fluid.

[0021] 5. The present invention sets a valve body mechanism. After the fluid passes through the upper half plate, the initial impact force will cause the support rod to rotate, and the rotating block will be blocked by the positioning block, so that the upper half plate can only be rotated ninety degrees, thereby changing the positional relationship between the upper half plate and the fluid flow direction, and making the conical block face the fluid, thereby minimizing the loss of fluid pressure caused by the upper half plate.

[0022] 6. The present invention sets a cleaning mechanism. After the sealing plate is removed, the telescopic rod three drives the support plate three to move to the inside of the four-way joint. The servo motor then drives the telescopic rod three and the support plate three to rotate. The centrifugal force generated will stretch the telescopic spring two and cause the cleaning cotton to rub against the inner wall of the four-way head, thereby absorbing the oil stains, dust and impurities attached to the four-way joint, avoiding the influence of these impurities on the fluid flow rate. After the telescopic rod three is reset, the servo motor three is started again, so that the cleaning cotton comes into contact with the scratch plate, and the scratch plate will scrape off the stains on the cleaning cotton, thereby realizing self-cleaning.

DETAILED DESCRIPTION

[0038] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0039] Example 1, using Figure 1-Figure 14 A dual-discharge high-pressure manifold for fracturing according to one embodiment of the present invention is described below.

[0040] like Figure 1-Figure 3 As shown, a double-discharge high-pressure manifold for fracturing of the present invention comprises a bottom plate 1, a support frame 2 is symmetrically arranged on the top of the bottom plate 1, the bottom of the support frame 2 is fixedly connected to the top of the bottom plate 1, a middle mechanism 3 is fixedly connected to the inner wall of the support frame 2, one end of the middle mechanism 3 is fixedly connected to a valve body mechanism 4, one end of the middle mechanism 3 away from the valve body mechanism 4 is fixedly connected to a space mechanism 5, one end of the space mechanism 5 away from the middle mechanism 3 is fixedly connected to a three-way mechanism 6, and the top of the bottom plate 1 is fixedly connected to a cleaning mechanism 7;

[0041] like Figure 6-Figure 7 As shown, the space mechanism 5 includes a connecting tube 1 51, the outer surface of the connecting tube 1 51 is fixedly connected to a space shell 52, the outer surface of the space shell 52 is evenly provided with a compression mechanism 54, the end of the space shell 52 away from the connecting tube 1 51 is fixedly connected to a connecting tube 2 53, the inner wall of the connecting tube 1 51 is provided with a conical surface 1 57, the conical surface 1 57 is fixedly connected to a fixing block 55, the outer surface of the fixing block 55 is fixedly connected to a toughness sleeve 56, and the inner wall of the connecting tube 2 53 is provided with a conical surface 2 58;

[0042] When the fluid flows into and out of the space shell 52, since the radius of the inflow and outflow pipes is different from the radius of the pipes inside the space shell 52, a fault will be formed, which will cause a large pressure loss in the flow. By setting a conical surface 1 57 and a conical surface 2 58 in the connecting pipe 1 and the connecting pipe 2 53 on both sides and using a conical transition section, the fluid can flow smoothly and reduce some pressure losses. After passing through the conical surface 1 57, the fluid will enter the semi-arc plate 546 through the deformable tough sleeve 56, so that the entire process will not produce an interface or fault perpendicular to the flow direction.

[0043] like Figure 8As shown, the compression mechanism 54 includes a support arm 541, which is evenly arranged on the outer surface of the space shell 52, and the end of the support arm 541 away from the space shell 52 is fixedly connected to a support plate 542, and the outer surface of the support plate 542 is fixedly connected to a hydraulic device 543, and the side of the hydraulic device 543 away from the support plate 542 is fixedly connected to a telescopic rod 544, and the end of the telescopic rod 544 away from the hydraulic device 543 is fixedly connected to a sealing block 545, and the end of the sealing block 545 away from the telescopic rod 544 is fixedly connected to a semi-arc plate 546, and the inner wall of the semi-arc plate 546 is slidably connected to an inner plate 547, and the outer surface of the inner plate 547 is fixedly connected to the outer surface of the adjacent semi-arc plate 546.

[0044] When the fracturing fluid passes through the high-pressure manifold, the radius of the pipeline will affect the pressure flowing in the pipeline. For flows requiring different pressures, the suitable pipeline size will also change accordingly. After the fracturing fluid enters the space shell 52, the hydraulic device 543 will drive the telescopic rod 544 to move inward, thereby driving the semi-arc plate 546 to move inward. At the same time, due to the proximity of the four semi-arc plates 546, the inner plate 547 between the two semi-arc plates 546 will also slide along the inner wall of one of the semi-arc plates 546, thereby controlling the size of the pipeline radius and avoiding a large pressure loss caused by an overly large pipeline during the flow of the fracturing fluid.

[0045] One end of the support arm 541 is fixedly connected to the outer surface of the space shell 52 , and the outer surface of the semi-arc plate 546 is fixedly connected to one end of the flexible sleeve 56 away from the fixed block 55 .

[0046] like Figure 4-Figure 5 As shown, the middle mechanism 3 includes a four-way joint 31, the outer surface of the four-way joint 31 is fixedly connected to a male straight pipe 1 33, the outer surface of the male straight pipe 1 33 is fixedly connected to a male straight pipe 2 34, the male straight pipe 1 33 and the male straight pipe 2 34 are perpendicular to each other, and discharge flanges 35 are symmetrically arranged at both ends of the male straight pipe 1 33, the top of the four-way joint 31 is fixedly connected to a pressure sensor 32, the bottom of the pressure sensor 32 is fixedly connected to a pressure test rod 36, and the bottom of the four-way joint 31 is fixedly connected to a sealing plate 37.

[0047] The pressure test rod 36 can test the flow rate pressure of the flowing fracturing fluid and display it on the pressure sensor 32. The discharge flange 35 is used to connect to external pipelines or equipment.

[0048] The specific workflow is as follows:

[0049] During operation, when the fluid flows into and out of the space shell 52, since the radius of the inflow and outflow pipes is different from the radius of the pipes in the space shell 52, a fault will be formed, which will cause a large pressure loss in the flow. By setting a conical surface 1 57 and a conical surface 2 58 in the connecting pipe 1 and the connecting pipe 2 53 on both sides and using a conical transition section, the fluid flow can be smoother and a part of the pressure loss can be reduced. The fluid will also enter the semi-arc plate 546 through the deformable tough sleeve 56 after passing through the conical surface 1 57, so that the whole process will not produce an interface and fault perpendicular to the flow direction. At the same time, the hydraulic device 543 will drive the telescopic rod 1 544 to move inward, thereby driving the semi-arc plate 546 to move inward. At the same time, due to the proximity of the four semi-arc plates 546, the inner plate 547 between the two semi-arc plates 546 will also slide along the inner wall of one of the semi-arc plates 546, thereby controlling the size of the pipe radius and avoiding a large pressure loss caused by the excessively large pipe during the flow of the fracturing fluid.

[0050] Embodiment 2, use Figure 1-Figure 14 A dual-discharge high-pressure manifold for fracturing according to one embodiment of the present invention is described below.

[0051] like Figure 9-10 As shown, a double-discharge high-pressure manifold for fracturing of the present invention is based on the first embodiment, and the three-way mechanism 6 includes a three-way pipe 61, the top of the three-way pipe 61 is fixedly connected with a top block 62, the inner wall of the top block 62 is fixedly connected with a fixing column 63, the fixing column 63 passes through the outer surface of the three-way pipe 61 and extends to the inner wall, the outer surface of the fixing column 63 is symmetrically provided with tough plates 64, the outer surface of the fixing column 63 is fixedly connected with a support plate 2 65, the support plate 2 65 is located between the tough plates 64 on both sides, the outer surface of the support plate 2 65 is evenly provided with telescopic springs 1 66, and the end of the telescopic spring 1 66 away from the support plate 2 65 is fixedly connected to the outer surface of the tough plate 64.

[0052] After the fluid enters the three-way pipe 61, the fluid will move along the flexible plate 64 to the two sides of the three-way pipe 61, avoiding the pressure loss caused by the fluid directly impacting the inner wall of the three-way pipe 61. Since the support plate 2 65 and the telescopic spring 1 66 support the flexible plate 64, the flexible plate 64 will be deformed after being impacted by the fluid. The greater the pressure of the fluid and the faster the flow rate, the greater the impact force of the telescopic spring 1 66 and the flexible plate 64, thereby making the flexible plate 64 bend with a larger arc, making the fluid circulation more convenient.

[0053] One side of the three-way pipe 61 close to the space mechanism 5 is fixedly connected to one end of the second connecting pipe 53 away from the space shell 52 .

[0054] like Figure 11-Figure 12As shown, the valve body mechanism 4 includes a valve tube 41, the top of the valve tube 41 is fixedly connected to a valve seat 42, the top of the valve seat 42 is rotatably connected to a rotating handle 43, the bottom of the rotating handle 43 is fixedly connected to a threaded rod 45, the bottom of the threaded rod 45 is fixedly connected to a baffle 46, the outer surface of the valve tube 41 is symmetrically provided with positioning blocks 44, the inner wall of the valve tube 41 is rotatably connected to a support rod 48, the outer surface of the support rod 48 is fixedly connected to an upper half plate 47, both ends of the support rod 48 are fixedly connected to rotating blocks 410, the bottom of the upper half plate 47 is fixedly connected to a conical block 411, and the inner wall of the valve tube 41 is fixedly connected to a lower plate mechanism 49.

[0055] By controlling the rotation of the rotating handle 43, the threaded rod 45 and the baffle 46 are driven upward to allow the fluid to pass through. After the fluid passes through the upper plate 47, the initial impact force will cause the support rod 48 to rotate, and the rotating block 410 will be blocked by the positioning block 44, so that the upper plate 47 can only be rotated ninety degrees, thereby changing the positional relationship between the upper plate 47 and the fluid flow direction, and making the conical block 411 face the fluid, minimizing the loss of fluid pressure caused by the upper plate 47.

[0056] like Fig.13 As shown, the lower plate mechanism 49 includes a lower half plate 491, the inner wall of the lower half plate 491 is evenly provided with telescopic rods 492, the outer surface of the telescopic rods 492 is fixedly connected with a gradient plate 493, the inner wall of the gradient plate 493 is slidably connected with an inner arc plate 494, and the bottom of the inner arc plate 494 is fixedly connected to the top of the adjacent gradient plate 493.

[0057] When the fluid passes through the lower plate mechanism 49, the telescopic rod 492 will drive the four-layer gradient plate 493 to move different distances. At the same time, the inner arc plate 494 in the gradient plate 493 will also be pulled out, so that the lower half plate 491 forms a gradient shape, avoiding the lower half plate 491 directly causing pressure loss to the fluid.

[0058] One end of the valve tube 41 is fixedly connected to one end of the male straight tube 34 away from the four-way connector 31 , and the outer surface of the lower half plate 491 is fixedly connected to the inner wall of the valve tube 41 .

[0059] like Fig.14 As shown, the cleaning mechanism 7 includes a collecting plate 71, a servo motor 72 is fixedly connected to the center of the collecting plate 71, a telescopic rod 3 73 is fixedly connected to the output end of the servo motor 72, a support plate 3 74 is fixedly connected to the top of the telescopic rod 3 73, a telescopic spring 2 75 is fixedly connected to the inner wall of the support plate 3 74, a cleaning cotton 76 is fixedly connected to one end of the telescopic spring 2 75, support rods 2 77 are evenly arranged on the top of the collecting plate 71, the bottom of the support rods 2 77 is fixedly connected to the top of the collecting plate 71, and a scratch plate 78 is fixedly connected to the top of the support rods 2 77.

[0060] After the sealing plate 37 is removed, the telescopic rod three 73 drives the support plate three 74 to move to the inside of the four-way joint 31, and the servo motor 72 drives the telescopic rod three 73 and the support plate three 74 to rotate. The centrifugal force generated will stretch the telescopic spring two 75 and cause the cleaning cotton 76 to rub against the inner wall of the four-way head, thereby absorbing the oil stains, dust and impurities attached to the four-way joint 31, avoiding the influence of these impurities on the fluid flow rate. After the telescopic rod three 73 is reset, the servo motor 72 is started again, so that the cleaning cotton 76 comes into contact with the scratch plate 78, and the scratch plate 78 will scrape off the stains on the cleaning cotton 76, thereby achieving self-cleaning.

[0061] The bottom of the collecting plate 71 is fixedly connected to the top of the bottom plate 1 , and one end of the connecting pipe 1 51 is fixedly connected to one end of the male straight pipe 2 34 away from the valve pipe 41 .

[0062] The specific workflow is as follows:

[0063] During operation, the threaded rod 45 and the baffle plate 46 are driven upward by controlling the rotation of the rotating handle 43, so that the fluid can pass through. When the fluid passes through the lower plate mechanism 49, the telescopic rod 2 492 will drive the four-layer gradient plate 493 to move different distances, and the inner arc plate 494 in the gradient plate 493 will also be pulled out, so that the lower half plate 491 forms a gradient shape. After that, after the fluid passes through the upper half plate 47, the initial impact force will cause the support rod 1 48 to rotate, and the rotating block 410 will be blocked by the blocking block 44, so that only the upper half plate 47 can be rotated ninety degrees, thereby changing the upper half plate 47. The positional relationship between the half plate 47 and the fluid flow direction makes the conical block 411 face the fluid. After the fluid enters the three-way pipe 61, the fluid will move to the two sides of the three-way pipe 61 along the flexible plate 64, avoiding the pressure loss caused by the fluid directly impacting the inner wall of the three-way pipe 61. Due to the support of the support plate 2 65 and the telescopic spring 1 66 on the flexible plate 64, the flexible plate 64 will be deformed after being impacted by the fluid. The greater the pressure of the fluid and the faster the flow rate, the greater the impact force of the telescopic spring 1 66 and the flexible plate 64, thereby making the bending arc of the flexible plate 64 larger, making it more convenient for the circulation of the fluid.

[0064] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
