Description

Technical Field

[0001] The utility model relates to the technical field of pressure reduction, and particularly relates to an energy-saving oil pressure reduction device. Background Art

[0002] In the refining and petrochemical industries, the oil pressure reduction device is an indispensable and important piece of equipment. The traditional oil pressure reduction device mainly reduces the oil pressure through a single pressure reducing valve or pressure reducing plate. When dealing with complex and changeable working conditions, this design often has problems such as poor pressure reduction effect, high energy consumption, and high equipment maintenance costs.

[0003] At present, the existing pressure reducing valve or pressure reducing plate often has an unsatisfactory pressure reduction effect when facing high-flow oil. Due to the relatively fast flow rate of the oil, the pressure reducing valve or pressure reducing plate may not be able to fully absorb the pressure energy in the oil, resulting in a still relatively high pressure of the oil after pressure reduction, which cannot meet the requirements of the subsequent process for the oil pressure. Therefore, we propose an energy-saving oil pressure reduction device to solve the above problems. Summary of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides an energy-saving oil pressure reduction device, which solves the problems raised in the above background art.

[0006] (2) Technical Solutions

[0007] The utility model specifically adopts the following technical solutions to achieve the above purposes:

[0008] An energy-saving oil pressure reduction device includes a main body of the pressure reduction device. A first connecting pipe is connected and fixed to the right side of the main body of the pressure reduction device, and a second connecting pipe is connected and fixed to the left side of the main body of the pressure reduction device. A plurality of pressure reducing plates are fixedly connected to the inner wall of the main body of the pressure reduction device in a circular shape. A flow rate sensor is fixedly connected to the bottom inner wall of the second connecting pipe. A circular block is fixedly connected to the inner wall of the main body of the pressure reduction device. A trapezoidal groove is formed in the circular block, and a through hole is formed in one inner wall of the trapezoidal groove. A rectangular plate is welded to the rear inner wall of the main body of the pressure reduction device. A connecting rod is provided on the rectangular plate. A trapezoidal block is welded to one end of the connecting rod. The trapezoidal block is in movable contact with the trapezoidal groove. The other end of the connecting rod is fixedly connected to a trapezoidal block. An electric push rod is provided above the main body of the pressure reduction device. The output end of the electric push rod extends into the main body of the pressure reduction device and is fitted with a ball. The ball is in rolling contact with the trapezoidal block. A spring is welded between one side of the trapezoidal block and one side of the rectangular plate. A processor is provided on the top of the main body of the pressure reduction device.

[0009] Furthermore, the spring is movably sleeved on the connecting rod.

[0010] Further, the electric push rod, the flow rate sensor and the processor are electrically connected through transmission wires.

[0011] Further, flange plates are fixedly connected to the ends of the first connecting pipe and the second connecting pipe.

[0012] Further, a guiding hole is formed in the rectangular plate, and the rectangular plate is slidably connected to the connecting rod through the guiding hole.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present utility model provides an energy-saving oil pressure reducing device, which has the following beneficial effects:

[0016] In the present utility model, the oil first enters the pressure reducing device main body through the first connecting pipe, and passes through the through hole and the frustum-shaped groove. When the oil meets the pressure reducing plate, multiple pressure reducing plates form a multi-stage pressure reducing structure, ensuring that part of the pressure can be effectively released when the oil flows through each stage of the pressure reducing plate. At the same time, the multi-stage pressure reducing design helps to avoid excessive impact and energy loss caused by too fast oil flow rate, and reduces the pressure. The flow rate sensor monitors the flow rate of the oil in the pressure reducing device main body in real time, and transmits the data to the processor to control the electric push rod to make corresponding adjustments. The oil after multi-stage pressure reduction and flow rate adjustment finally flows out stably through the second connecting pipe, so that multi-stage pressure reduction can be achieved. At the same time, by adjusting the flow rate of the oil, the pressure reducing effect can be further optimized and the energy loss can be reduced. Description of the Drawings

A first connecting pipe 2 is connected and fixed to the right side of the pressure reducing device main body 1. A second connecting pipe 3 is connected and fixed to the left side of the pressure reducing device main body 1. A plurality of pressure reducing plates 4 are fixedly connected to the inner wall of the pressure reducing device main body 1 in a ring shape. A flow velocity sensor 5 is fixedly connected to the bottom inner wall of the second connecting pipe 3. A circular block 6 is fixedly connected to the inner wall of the pressure reducing device main body 1. A trapezoidal groove 7 is opened on the circular block 6. A through hole 8 is opened on one inner wall of the trapezoidal groove 7. A rectangular plate 9 is welded to the rear inner wall of the pressure reducing device main body 1. A connecting rod 10 is provided on the rectangular plate 9. A trapezoidal block 11 is welded to the end of the connecting rod 10. The trapezoidal block 11 is in movable contact with the trapezoidal groove 7. The other end of the connecting rod 10 is fixedly connected to a trapezoidal block 12. An electric push rod 14 is provided above the pressure reducing device main body 1. The output end of the electric push rod 14 extends into the pressure reducing device main body 1 and is fitted with a ball 15. The ball 15 is in rolling contact with the trapezoidal block 12. A spring 13 is welded between one side of the trapezoidal block 12 and one side of the rectangular plate 9. A processor 16 is provided on the top of the pressure reducing device main body 1. The oil first enters the pressure reducing device main body 1 through the first connecting pipe 2. When the oil passes through the through hole 8 and the trapezoidal groove 7 and encounters the pressure reducing plates 4, the plurality of pressure reducing plates 4 form a multi-stage pressure reducing structure, ensuring that part of the pressure can be effectively released when the oil flows through each stage of the pressure reducing plate 4. At the same time, the multi-stage pressure reducing design helps to avoid excessive impact and energy loss caused by too fast oil flow velocity, and reduces the pressure. The flow velocity sensor 5 monitors the oil flow velocity in the pressure reducing device main body 1 in real time and transmits the data to the processor 16 to control the electric push rod 14 to make corresponding adjustments. The electric push rod 14 pushes the trapezoidal block 12 through the ball 15. The trapezoidal block 12 compresses the spring 13 during the movement. The trapezoidal block 12 drives the trapezoidal block 11 to move through the connecting rod 10. The trapezoidal block 11 contacts the trapezoidal groove 7, causing the flow velocity of the oil to change. The oil after multi-stage pressure reduction and flow velocity adjustment finally discharges stably through the second connecting pipe 3, so that multi-stage pressure reduction can be achieved. At the same time, by adjusting the flow velocity of the oil, the pressure reducing effect can be further optimized and energy loss can be reduced.

[0025] In some embodiments, the spring 13 is movably sleeved on the connecting rod 10. The setting of the spring 13 plays a role in resetting.

[0026] In some embodiments, the electric push rod 14, the flow rate sensor 5 and the processor 16 are electrically connected through transmission wires.

[0027] In some embodiments, flange plates 17 are fixedly connected to the ends of the first connecting pipe 2 and the second connecting pipe 3.

[0028] In some embodiments, a guiding hole is formed in the rectangular plate 9. The rectangular plate 9 is slidably connected to the connecting rod 10 through the guiding hole. The setting of the connecting rod 10 plays a role in connection.

[0029] In some embodiments, a mounting hole is formed in the inner wall of the top of the decompression device main body 1. The decompression device main body 1 is fixedly connected to the outside of the electric push rod 14 through the mounting hole. The setting of the electric push rod 14 realizes automation.

[0030] · Working principle or structural principle: During use, it is connected to an external pipeline through the flange plate 17. The oil fluid first enters the decompression device main body 1 through the first connecting pipe 2, passes through the through hole 8 and the frustum-shaped groove 7. When the oil fluid encounters the decompression plate 4, multiple decompression plates 4 form a multi-stage decompression structure, ensuring that part of the pressure can be effectively released when the oil fluid flows through each stage of the decompression plate 4. At the same time, the multi-stage decompression design helps to avoid excessive impact and energy loss caused by too fast flow rate of the oil fluid, and reduces the pressure. The flow rate sensor 5 monitors the flow rate of the oil fluid in the decompression device main body 1 in real time, and transmits the data to the processor 16 to control the electric push rod 14 to make corresponding adjustments. The electric push rod 14 pushes the trapezoidal block 12 through the ball 15. During the movement of the trapezoidal block 12, the spring 13 is compressed. The trapezoidal block 12 drives the frustum-shaped block 11 to move through the connecting rod 10. The frustum-shaped block 11 contacts the frustum-shaped groove 7, causing the flow rate of the oil fluid to change. The oil fluid after multi-stage decompression and flow rate adjustment finally flows out stably through the second connecting pipe 3, so that multi-stage decompression can be achieved. At the same time, by adjusting the flow rate of the oil fluid, the decompression effect can be further optimized and energy loss can be reduced.
