Description

Technical Field

[0001] This application relates to the field of measuring equipment technology, specifically to a manual portable pressure source. Background Technology

[0002] In the current field of fluid pressure testing, electric pressure pumps are often used to provide test pressure. Although electric pressure pumps can provide stable pressure output, they have problems such as large size, dependence on power supply, and inconvenience for field operations. Therefore, it is necessary to design a manual portable pressure source.

[0003] A related manual portable pressure source includes an oil tank, a pressurizing component, a pressure gauge, and an output component. The operator operates the pressurizing component to pressurize the hydraulic oil in the oil tank and enter the output component. The pressure gauge detects the pressure value of the hydraulic oil in the output component. The output component is connected to the equipment to be tested, thereby completing the pressure test on the equipment.

[0004] However, the existing manual portable pressure source can only output one type of pressure to the testing device when in use, and the detection range is small, which cannot meet the testing experiments that require multiple pressure outputs at the same time. Utility Model Content

[0005] To address the issue that manual portable pressure sources can only provide one type of pressure output, this application provides a manual portable pressure source.

[0006] This application provides a manual portable pressure source, employing the following technical solution:

[0007] A manual portable pressure source includes:

[0008] A fixed base is fixedly installed on the ground, and an oil pipe is installed inside the fixed base.

[0009] The fuel tank is horizontally fixed on a fixed base, and an oil chamber is horizontally arranged inside the fuel tank.

[0010] The pressurizing component is fixedly mounted on the fixed base and is connected to the oil chamber through an oil pipe.

[0011] The adjustment component is fixedly mounted on the base and is connected to the pressurization component via an oil pipe.

[0012] The pressure gauge is fixedly mounted on a fixed base and is connected to the adjustment assembly via an oil pipe.

[0013] The output component is fixedly mounted on the base and is connected to the pressure gauge via an oil pipe.

[0014] By adopting the above technical solution, the fixed base provides installation space for the oil tank, pressurizing component, adjusting component, pressure gauge, and output component. The oil tank provides storage space for hydraulic oil. The pressurizing component can pressurize the hydraulic oil in the oil tank and inject it into the adjusting component. The operator can finely adjust the pressure of the hydraulic oil through the adjusting component. The pressure gauge allows the operator to monitor the pressure of the hydraulic oil in real time. The pressurized hydraulic oil in the adjusting component can enter the output component through the oil pipe. The operator can output the hydraulic oil in the output component to the testing equipment with various pressures, enabling the operator to complete the testing experiment.

[0015] Optional, the pressurization components include:

[0016] A sleeve is fixedly mounted on a fixed base. A sliding cavity is vertically provided on the sleeve. The lower end of the sliding cavity is connected to the oil cavity through an oil pipe. The lower end of the sliding cavity is also connected to the adjustment component through an oil pipe.

[0017] The piston has one end vertically inserted into the sliding cavity, and is slidably connected to the sleeve. The other end of the piston extends out of the sliding cavity.

[0018] The handle is rotatably connected to the end of the piston furthest from the sleeve.

[0019] A connecting rod, one end of which is rotatably connected to the handle, and the other end of which is rotatably connected to the fixed base;

[0020] A one-way valve is installed at the connection between the sleeve and the oil pipe.

[0021] By adopting the above technical solution, the operator can control the end of the handle away from the connecting rod to move the piston along the axis of the sleeve. When the piston moves away from the fixed base along the sleeve, a negative pressure is formed in the sliding chamber, causing the hydraulic oil in the oil tank to flow into the sliding chamber through the one-way valve. When the piston moves closer to the fixed base along the sleeve, the space inside the sliding chamber decreases, the hydraulic oil in the sliding chamber is pressurized and flows out of the sliding chamber through the one-way valve. The operator reciprocates the operation of the handle to rotate, thereby achieving the purpose of continuous pressurization output of hydraulic oil under the condition of no power supply.

[0022] Optional, the adjustment components include:

[0023] An adjusting block is horizontally fixed on a fixed base and has an adjusting cavity.

[0024] A connecting frame, which passes through the adjustment cavity;

[0025] The threaded rod passes through the adjusting block and is threadedly connected to the connecting frame. The end of the adjusting cavity away from the threaded rod is connected to the pressurizing assembly through an oil pipe.

[0026] By adopting the above technical solution, the adjusting block provides installation space for the connecting frame. The rotation of the threaded rod can drive the connecting frame to move along the length of the adjusting cavity, thereby changing the volume of hydraulic oil in the adjusting cavity, thus achieving the purpose of precise adjustment of the hydraulic oil pressure in the adjusting cavity and oil pipe.

[0027] Optional, output components include:

[0028] The reversing block is fixedly mounted on the fixed base. The reversing block has a vertical reversing groove and multiple sets of oil outlet holes spaced apart.

[0029] The reversing valve is installed in the reversing groove and is rotatably connected to the reversing block. The reversing valve is provided with an oil inlet hole, which is connected to the oil pipe.

[0030] The output block is fixedly mounted on the fixed base. Multiple sets of output blocks are arranged horizontally at intervals. The output block is vertically mounted with an output cavity, which is connected to the oil outlet through an oil pipe.

[0031] The output tube is vertically fixed at the upper end of the output block and is connected to the output cavity.

[0032] The pressure relief valve is fixedly installed on the fixed base. One end of the pressure relief valve is connected to the output chamber through an oil pipe, and the other end of the pressure relief valve is connected to the oil chamber through an oil pipe.

[0033] By adopting the above technical solution, the reversing block and reversing valve work together to allow the hydraulic oil in the oil pipe to flow into different output chambers through multiple sets of oil outlet holes, thereby realizing the diversion and output of hydraulic oil. The hydraulic oil in the output chamber can be connected to multiple sets of equipment through the output pipe. After the equipment pressure test is completed, the operator can open the pressure relief valve to allow the hydraulic oil in the output chamber to flow back into the oil tank. The setting of multiple output blocks meets the testing needs of manual portable pressure source to perform multiple pressure output requirements at the same time, expands the application range of manual portable pressure source, and improves the work efficiency of the operator.

[0034] Optionally, a filler hole is fixedly provided on the fuel tank, and the filler hole is connected to the fuel chamber.

[0035] By adopting the above technical solution, the oil filling port allows operators to replenish hydraulic oil in the tank in a timely manner, reducing the situation where the manual portable pressure source cannot be used due to insufficient hydraulic oil, ensuring the continuous and stable operation of the equipment, and improving the pressure output range of the manual portable pressure source.

[0036] Optionally, a rotating block is fixedly installed at the end of the threaded rod away from the connecting frame.

[0037] By adopting the above technical solution, the rotating block is designed to facilitate the rotation of the threaded rod by the operator, reducing the difficulty of operation and improving the efficiency of adjusting the hydraulic oil pressure.

[0038] Optionally, a sealing gasket is fixedly provided at the end of the connecting bracket away from the threaded rod.

[0039] By adopting the above technical solution, the sealing gasket improves the sealing performance between the connecting frame and the adjustment cavity, reduces the occurrence of hydraulic oil leakage, and improves the working stability of the manual portable pressure source.

[0040] Optionally, an output valve may be installed on the output pipe.

[0041] By adopting the above technical solution, the output valve allows the operator to control the opening and closing of the output pipe, and to control the pressure of the hydraulic oil in the output chamber, thus achieving precise control of the output pressure of the manual portable pressure source.

[0042] In summary, this utility model embodiment provides a manual portable pressure source, which includes at least one of the following beneficial technical effects:

[0043] 1. The fixed base provides installation space for the oil tank, pressurizing component, adjusting component, pressure gauge, and output component. The oil tank provides storage space for hydraulic oil. The pressurizing component can pressurize the hydraulic oil in the tank and inject it into the adjusting component. Operators can finely adjust the pressure of the hydraulic oil through the adjusting component. The pressure gauge allows operators to monitor the pressure of the hydraulic oil in real time. The pressurized hydraulic oil in the adjusting component can enter the output component through the oil pipe. Operators can output various pressures to the testing equipment using the hydraulic oil in the output component, enabling them to complete the testing experiments.

[0044] 2. The operator can control the end of the handle away from the connecting rod to move the piston along the axis of the sleeve. When the piston moves away from the fixed base along the sleeve, a negative pressure is formed in the sliding chamber, causing the hydraulic oil in the tank to flow into the sliding chamber through the one-way valve. When the piston moves closer to the fixed base along the sleeve, the space inside the sliding chamber decreases, the hydraulic oil in the sliding chamber is pressurized and flows out of the sliding chamber through the one-way valve. The operator reciprocates by rotating the handle, thereby achieving the purpose of continuous pressurization output of hydraulic oil under the condition of no power supply.

[0054] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0055] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses a manual portable pressure source, including: a fixed base 41, an oil tank 42, a pressurizing component 1, an adjusting component 2, a pressure gauge 43, and an output component 3; the fixed base 41 is fixedly installed on the ground, and an oil pipe 44 is installed inside the fixed base 41; the oil tank 42 is horizontally fixedly installed on the fixed base 41, and an oil chamber 48 is horizontally installed inside the oil tank 42; the pressurizing component 1 is fixedly installed on the fixed base 41 and is connected to the oil chamber 48 through the oil pipe 44; the adjusting component 2 is fixedly installed on the fixed base 41 and is connected to the pressurizing component 1 through the oil pipe 44; the pressure gauge 43 is fixedly installed on the fixed base 41 and is connected to the adjusting component 2 through the oil pipe 44; the output component 3 is fixedly installed on the fixed base 41 and is connected to the pressure gauge 43 through the oil pipe 44.

[0056] In this embodiment, the fixed base 41 is rectangular, and an oil pipe 44 is provided inside the fixed base 41, allowing hydraulic oil to flow between the various components through the oil pipe 44. The oil tank 42 is rectangular, and the oil chamber 48 is rectangular. An oil filling hole 49 is fixedly provided on the oil tank 42, and the oil filling hole 49 communicates with the oil chamber 48. The operator can add hydraulic oil to the oil tank 42 in a timely manner through the oil filling hole 49 to ensure that the oil level in the oil tank 42 is sufficient and to maintain the normal operation of the manual portable pressure source. The operator can manually control the pressurization component 1 to draw hydraulic oil from the oil tank 42 and pressurize it. Within the adjustment component 2, operators can manually adjust the adjustment component 2 to achieve minute pressure regulation of the hydraulic oil within it. The pressure gauge 43 can monitor the pressure value of the hydraulic oil within the adjustment component 2 in real time, facilitating the operator's reading of pressure data. The pressure detection principle of the pressure gauge 43 is existing technology in the field, therefore, the pressure detection principle of the pressure gauge 43 in this embodiment will not be specifically described. Operators can manually control the output component 3 to change the output direction of the hydraulic oil, enabling the hydraulic oil to output various pressures to the testing equipment, thus expanding the application range of the manual portable pressure source.

[0057] In practical use, the operator connects the output component 3 to different detection positions of the testing equipment. The operator injects hydraulic oil into the oil chamber 48 through the oil filler port. The operator manually operates the pressurizing component 1, which pressurizes the hydraulic oil in the oil chamber 48 and injects it into the adjusting component 2. The operator observes the pressure value of the hydraulic gauge. At the same time, the operator manually controls the adjusting component 2 to change the pressure of the hydraulic oil so that the pressure value of the hydraulic oil reaches the set value required by the testing equipment. The operator controls the output component 3 to make the hydraulic oil output pressure to different detection positions of the testing equipment, thereby completing the testing experiment of the testing equipment.

[0058] Combination Figure 1 and Figure 2 In one specific embodiment, the pressurizing component 1 includes: a sleeve 11, a piston 12, a handle 13, a connecting rod 14, and a one-way valve 15; the sleeve 11 is fixedly mounted on the fixed base 41, and a sliding cavity 50 is vertically mounted on the sleeve 11. The lower end of the sliding cavity 50 is connected to the oil cavity 48 through the oil pipe 44, and the lower end of the sliding cavity 50 is connected to the adjusting component 2 through the oil pipe 44. One end of the piston 12 is vertically inserted into the sliding cavity 50, and the piston 12 is slidably connected to the sleeve 11. The other end of the piston 12 extends to the outside of the sliding cavity 50. The handle 13 is rotatably connected to the end of the piston 12 away from the sleeve 11. One end of the connecting rod 14 is rotatably connected to the handle 13, and the other end of the connecting rod 14 is rotatably connected to the fixed base 41. The one-way valve 15 is located at the connection between the sleeve 11 and the oil pipe 44.

[0059] In this embodiment, the sleeve 11 is rectangular, the sliding cavity 50 is rectangular, and the piston 12 is rectangular, with the piston 12 tightly fitted to the inner wall of the sleeve 11. The one-way valve 15 ensures that the hydraulic oil in the oil chamber 48 flows only unidirectionally into the sliding cavity 50, and simultaneously, the hydraulic oil in the sliding cavity 50 flows only unidirectionally into the adjusting component 2, ensuring consistent hydraulic oil flow and reducing backflow. The unidirectional flow principle of the one-way valve 15 is existing technology in this field, therefore, the unidirectional flow principle of the one-way valve 15 is not specifically described in this embodiment. The operator can use the connecting rod 14 as a fulcrum, and the operator can control... When the handle 13 rotates, it can drive the piston 12 to move along the axis of the sliding cavity 50 through the lever principle, which reduces the workload of the operator and improves the operator's operating efficiency. When the piston 12 moves away from the fixed base 41 along the axis of the sliding cavity 50, a negative pressure is formed in the sliding cavity 50, thereby drawing the hydraulic oil in the oil chamber 48 into the sliding cavity 50. When the piston 12 moves closer to the fixed base 41 along the axis of the sliding cavity 50, the space in the sliding cavity 50 is reduced, the hydraulic oil is compressed, the pressure of the hydraulic oil increases and flows into the adjustment component 2 through the one-way valve 15, thus completing the process of pressurizing and injecting the hydraulic oil into the adjustment component 2.

[0060] In practical use, the operator manipulates the handle 13 to rotate around the connecting rod 14 and the rotating connection of the handle 13. When the handle 13 moves away from the fixed base 41, the piston 12 moves away from the fixed base 41 along the axis of the sliding cavity 50, increasing the space inside the sliding cavity 50 and creating a negative pressure inside the sliding cavity 50, which draws hydraulic oil into the sliding cavity 50 through the one-way valve 15. When the handle 13 moves closer to the fixed base 41, the piston 12 moves closer to the fixed base 41 along the axis of the sliding cavity 50, decreasing the space inside the sliding cavity 50, and the hydraulic oil is pressurized and flows into the adjustment component 2 through the one-way valve 15. In this way, the operator can repeatedly rotate the handle 13 to drive the hydraulic oil in the oil tank 42 to flow steadily and pressurized into the adjustment component 2.

[0061] Combination Figure 1 and Figure 3 In one specific embodiment, the adjustment component 2 includes: an adjustment block 21, a connecting frame 22, and a threaded rod 23. The adjustment block 21 is horizontally fixed on the fixed base 41, and an adjustment cavity 51 is provided on the adjustment block 21. The connecting frame 22 passes through the adjustment cavity 51, and the threaded rod 23 passes through the adjustment block 21. The threaded rod 23 is threadedly connected to the connecting frame 22. The end of the adjustment cavity 51 away from the threaded rod 23 is connected to the pressurization component 1 through an oil pipe 44.

[0062] In this embodiment, the adjusting block 21 is rectangular, the adjusting cavity 51 is rectangular, the threaded rod 23 is cylindrical, and the connecting frame 22 is rectangular. The connecting frame 22 is tightly fitted to the inner wall of the adjusting block 21. One end of the threaded rod 23 is rotatably connected to the connecting frame 22, and the other end of the threaded rod 23 extends through the adjusting block 21 to the outside of the adjusting cavity 51. A rotating block 45 is fixedly installed at the end of the threaded rod 23 away from the connecting frame 22. The operator can drive the rotating block 45 to rotate, thereby driving the threaded rod 23 to rotate synchronously. The rotation of the threaded rod 23 drives the connecting frame 22 to move along the axis of the adjusting cavity 51. A sealing gasket 46 is fixedly installed at the end of the connecting frame 22 away from the threaded rod 23. The sealing gasket 46 is tightly fitted to the inner wall of the adjusting block 21. When the connecting frame 22 moves, it can change the size of the space inside the adjusting cavity 51, thereby adjusting the pressure of the hydraulic oil.

[0063] In practical use, the operator controls the rotating block 45 to rotate, which drives the threaded rod 23 to rotate synchronously. The rotation of the threaded rod 23 drives the connecting frame 22 to move along the axis of the adjusting cavity 51. When the connecting frame 22 moves away from the threaded rod 23, the space inside the adjusting cavity 51 decreases and the pressure of the hydraulic oil increases. When the connecting frame 22 moves closer to the threaded rod 23, the space inside the adjusting cavity 51 increases and the pressure of the hydraulic oil decreases, thereby achieving the purpose of the operator manually adjusting the pressure of the hydraulic oil in the portable pressure source.

[0064] Combination Figure 1 and Figure 4 In one specific embodiment, the output component 3 includes: a reversing block 31, a reversing valve 32, an output block 33, an output pipe 34, and a pressure relief valve 35. The reversing block 31 is fixedly mounted on a fixed base 41. A reversing groove 52 is vertically provided on the reversing block 31. Multiple sets of oil outlet holes 54 are spaced apart on the reversing block 31. The reversing valve 32 passes through the reversing groove 52 and is rotatably connected to the reversing block 31. An oil inlet hole 53 is provided on the reversing valve 32 and communicates with the oil pipe 44. The output block... Output blocks 33 are fixedly mounted on the fixed base 41. Multiple sets of output blocks 33 are horizontally spaced. Output chambers 55 are vertically mounted on the output blocks 33. Output chambers 55 are connected to oil outlets 54 through oil pipes 44. Output pipes 34 are vertically fixedly mounted on the upper end of the output blocks 33 and are connected to output chambers 55. Pressure relief valves 35 are fixedly mounted on the fixed base 41. One end of pressure relief valves 35 is connected to output chambers 55 through oil pipes 44, and the other end of pressure relief valves 35 is connected to oil chambers 48 through oil pipes 44.

[0065] In this embodiment, the reversing block 31 is rectangular, the reversing groove 52 is cylindrical, and the reversing valve 32 is cylindrical. The reversing valve 32 can rotate around the central axis of the reversing groove 52. The reversing valve 32 is tightly fitted to the inner wall of the reversing block 31. The reversing block 31 has multiple sets of oil outlet holes 54 inside. The multiple sets of oil outlet holes 54 are connected to the output chambers 55 in multiple sets of output blocks 33 through different oil pipes 44. One end of the oil inlet hole 53 is connected to the adjustment chamber 51 through the oil pipe 44, and the other end of the oil inlet hole 53 is correspondingly set with the oil outlet hole 54. When the operator rotates the reversing valve 32, the oil inlet hole 53 can be driven to rotate with the adjustment chamber 51. The step rotation controls the connection between the oil inlet 53 and different oil outlets 54, allowing the hydraulic oil in the adjustment chamber 51 to flow into different output chambers 55 through different oil outlets 54 and oil pipes 44. The output block 33 is rectangular, the output chamber 55 is cylindrical, and the output pipe 34 is cylindrical. An output valve 47 is installed on the output pipe 34. The operator controls the output valve 47 to allow the hydraulic oil in the output chamber 55 to flow into the testing equipment, and the operator controls the pressure relief valve 35 to allow the hydraulic oil in the output chamber 55 to flow into the oil chamber 48, thereby realizing the recycling and pressure regulation of hydraulic oil.

[0066] In practical use, the operator closes the pressure relief valve 35 and the output valve 47, and rotates the directional valve 32 to connect the oil inlet 53 with the designated oil outlet 54. The hydraulic oil in the adjustment chamber 51 flows into the output chamber 55 through the directional valve 32 and the directional block 31. When the pressure of the hydraulic oil reaches the pressure value required for the experiment, the operator rotates the directional valve 32 to connect the oil inlet 53 with other oil outlets 54, and the hydraulic oil flows into other output chambers 55 for pressure output experiment. The operator opens the output valve 47, and the high-pressure hydraulic oil in the output chamber 55 flows into the testing equipment to complete the testing experiment of the testing equipment. After the experiment is completed, the operator opens the pressure relief valve 35, and the high-pressure hydraulic oil in the output chamber 55 flows into the oil chamber 48 through the pressure relief valve 35 and the oil pipe 44 to realize the recovery of hydraulic oil and pressure release.

[0067] The implementation principle of this application is as follows: The operator closes the pressure relief valve 35 and the output valve 47. The operator connects multiple sets of output pipes 34 to different detection positions of the testing equipment. The operator injects sufficient hydraulic oil into the oil chamber 48 through the filler port. The operator controls the handle 13 to rotate reciprocally. The rotation of the handle 13 drives the piston 12 to move reciprocally along the axis of the sliding chamber 50. The movement of the piston 12 causes the hydraulic oil in the oil chamber 48 to flow into the sliding chamber 50 through the one-way valve 15 and be pressurized before flowing into the adjusting chamber 51. The operator controls the rotating block 45 and the threaded rod 23 to rotate. The rotation of the threaded rod 23 drives the connecting frame 22 to move along the axis of the adjusting chamber 51. The operator moves the hydraulic oil, thereby changing the size of the adjustment chamber 51 and the pressure of the hydraulic oil. The operator monitors the pressure of the hydraulic oil in real time through the pressure gauge 43. The operator rotates the reversing valve 32 to connect the oil inlet 53 with the corresponding oil outlet 54. The high-pressure hydraulic oil in the adjustment chamber 51 flows into the designated output chamber 55 through the reversing valve 32 and the reversing block 31. The operator opens the output valve 47, so that the high-pressure hydraulic oil in the output chamber 55 performs a pressure test on the testing equipment. After the test is completed, the operator closes the output valve 47 and opens the pressure relief valve 35. The high-pressure hydraulic oil in the output chamber 55 flows into the oil chamber 48 through the pressure relief valve 35.
