[0002] The multifunctional pressure relief operating table for the oil filling hose is a device specially designed to solve the problem of pressure buildup in the oil filling hose during the aviation kerosene filling process. Its main function and purpose is to automatically release the residual pressure in the oil filling hose after the filling operation is completed to prevent safety hazards such as oil filling hose bursting due to excessive pressure.

[0003] The multifunctional pressure relief operating table of the oil filling hose is mainly composed of a refueling hose, a control ball valve, a pressure relief loop pipe, a liquid check valve, a pressure gauge and other components. Its working principle is based on pressure control. When the refueling operation is completed, the control ball valve is closed. If the pressure in the refueling hose is higher than the preset safety threshold, the liquid check valve will automatically open to release the excessive pressure to a safe range. The operating process is simple and clear. You only need to monitor the pressure gauge to ensure that the system operates under a safe pressure.

A spiral block 614 is fixedly installed on the inner side of the filter cartridge 69, and a connecting gear 615 is fixedly installed on the outer side of the filter cartridge 69. A square filter plate 612 is fixedly installed on the inner side of the pressure relief cylinder 68, and a brush rod 613 is fixedly installed on the other end of the round rod 611. The square shell 616 is provided with a motor 617 fixedly mounted inside the square shell 616, a power gear 618 fixedly mounted at the output end of the motor 617, a protective shell 619 fixedly mounted inside the outer shell 1, a filter plate 620 fixedly mounted inside the filter cartridge 69, multiple groups of support legs 2, refueling connector placement blocks 3 and spiral blocks 614 are provided, and multiple groups of support legs 2 are arrayed at the four corners of the bottom of the outer shell 1 at equal intervals, and multiple groups of refueling connector placement blocks 3 are mirrored with the vertical midline of the front-to-back direction of the outer shell 1 as the mirror axis, and the mirror image is set on the outside of the outer shell 1, and multiple groups of spiral blocks 614 are arranged with the filter The center of the circular cross-section of the cylinder 69 is an equally spaced circular array at the center of the array, the pressure relief cylinder 68 is connected to the refueling joint docking port 61, the other end of the filter cylinder 69 is connected to the rear cleaning operation port 62, the round rod 611 penetrates the circular filter plate 612, the brush rod 613 is arranged on the inner side of the filter cylinder 69, the connecting gear 615 is engaged with the power gear 618, the connecting gear 615 and the power gear 618 are arranged on the inner side of the protective shell 619, the operating table countersunk mouth 66 is arranged at the bottom end of the inclined block 65, and a tool storage area is arranged above the partition 64 and between the cover plate 4.

[0038] When the present embodiment is used, the outer shell 1 is first used as the main frame of the device to provide protection and installation foundation for the internal components. The legs 2 below are arranged at equal intervals at the four corners of the bottom of the outer shell 1 to ensure that the entire operating table is stably placed in the working area. At the same time, two groups of refueling connector placement blocks 3 are arranged on the outer side of the outer shell 1 to facilitate the placement of the refueling connector, which is convenient for operators to quickly connect and use. At the same time, a certain space is formed between the cover plate 4 and the outer shell 1, and a tool storage area is provided above the partition plate 64 and between the cover plate 4, which can store common equipment such as oil-absorbing felt, rags, oil-resistant gloves, lead sealing wires, lead sealing beans, lead sealing pliers, etc., so that operators can use tools conveniently when operating and maintaining the oil filling hose. The refueling joint interface 61 is used to connect the oil filling hose joint so that the pressurized oil in the oil filling hose can enter the pressure relief system. The rear cleaning operation port 62 provides a channel for regular cleaning of the interior of the device to facilitate internal maintenance. The pressure gauge 63 monitors the oil pressure in real time. The operator can ensure that the pressure is within a safe range by observing the pressure gauge 63 to avoid the impact of excessive high or low pressure on the equipment and operation. Further, when the oil filling hose needs to be depressurized, the oil filling hose joint is connected to the refueling joint interface 61 on the outside of the housing 1, the oil filling joint handle is opened, and the oil enters the pressure relief cylinder 68. At this time, the filter cylinder 69 starts to rotate under the drive of the motor 617, and the filter The spiral block 614 and the filter plate 620 on the inner side of the filter cartridge 69 filter the incoming oil. The spiral block 614 generates centrifugal force by rotating, so that the impurities in the oil move toward the inner wall of the filter cartridge 69 under the action of the centrifugal force. The filter plate 620 further intercepts the impurities to achieve preliminary purification of the oil, thereby ensuring a uniform filtering effect on the oil. At the same time, when the filter cartridge 69 rotates, the round rod 611 and the brush rod 613 remain relatively still, and the brush rod 613 cleans the inner wall of the filter cartridge 69 on the inner side of the filter cartridge 69. The brush rod 613 can scrape off impurities that may be attached to the inner wall of the filter cartridge 69 to prevent excessive accumulation of impurities and blockage of the filter cartridge 69, thereby ensuring that the filtering performance of the filter cartridge 69 is maintained. Continuous stability ensures smooth filtration of the oil. At the same time, the pressure gauge 63 on the outside of the shell 1 continuously monitors the pressure changes of the oil during the pressure relief process. The operator can judge whether the pressure relief process is normal based on the indication of the pressure gauge 63 to ensure that the pressure is always within a safe range to prevent safety accidents caused by abnormal pressure. At the same time, the inclined block 65 on the inside of the shell 1 is located below the pressure relief cylinder 68. After the oil is filtered through the filter cylinder 69, some impurities that may remain will settle on the inclined block 65 under the action of gravity. The valve 67 on the outside is opened when it is necessary to discharge the impurities, and the impurities can be discharged out of the device through the discharge port 66 on the operating table, further ensuring the cleanliness of the oil and extending the service life of the equipment.

[0039] In one embodiment of the present invention, an auxiliary component 7 is provided on the inner side of the outer shell 1, and the auxiliary component 7 includes a long rod 71, the long rod 71 is fixedly installed on the output end of the motor 617, a square plate 72 is fixedly installed on the outer side of the long rod 71, a pressure relief box 73 is fixedly installed on the outer side of the pressure relief cylinder 68, a guide block 74 is fixedly installed on the inner side of the pressure relief cylinder 68, a square filter plate 75 is fixedly installed on the outer side of the guide block 74, and multiple groups of square plates 72 are provided, and the multiple groups of square plates 72 are arranged in a circular array with equal spacing around the center of the circular cross-section of the long rod 71 as the center of the array, the long rod 71 passes through one end of the pressure relief box 73, multiple groups of square plates 72 are arranged on the inner side of the pressure relief box 73, the pressure relief cylinder 68 is connected to the internal space of the pressure relief box 73, and the square filter plate 75 is arranged at the connection between the pressure relief cylinder 68 and the pressure relief box 73 in an inclined shape.

[0040] When the present embodiment is used, the motor 617 drives the long rod 71 to rotate, and at the same time drives the square plate 72 to rotate in the pressure relief box 73, so as to stir the oil in the pressure relief cylinder 68 and the pressure relief box 73. During the stirring process, impurities in the oil are more likely to gather under the action of pressure, and the guide block 74 on the inner side of the pressure relief cylinder 68 guides the flow direction of the oil, so that the oil flows more smoothly between the pressure relief cylinder 68 and the pressure relief box 73, ensuring that the square plate 72 can fully stir the oil. The rotation of the square plate 72 and its own structure increase the contact between the oil and the square filter plate 75 The square filter plate 75 has a large area, so that impurities are more easily intercepted by the square filter plate 75. At the same time, the square filter plate 75 located at the connection between the pressure relief cylinder 68 and the pressure relief box 73 is inclined. This design is conducive to the impurities to gather at a specific position along the inclined surface under the combined action of gravity and oil flow, which is convenient for cleaning. The stirring of the square plate 72 prompts the impurities to move to the square filter plate 75. After being filtered by the square filter plate 75, the purity of the oil is further improved, which effectively assists the pressure relief process, ensures the quality of the oil, provides better oil conditions for subsequent oil filling operations, and reduces the impact of impurities on the oil filling system.

[0041] In one embodiment of the present invention, a cleaning assembly 8 is provided on the inner side of the shell 1, and the cleaning assembly 8 includes a thick cylinder 81, a thick cylinder 81 is fixedly installed on the inner side of the shell 1, one end of a thick spring 82 is fixedly installed on the inner side of the thick cylinder 81, and one end of a thin cylinder 83 is fixedly installed on the other end of the thick spring 82, and one end of a thin spring 84 is fixedly installed on the inner side of the thin cylinder 83, and a hinge block 85 is fixedly installed on the other end of the thin spring 84, and a round ball 86 is hingedly installed on the other end of the hinge block 85, and a cleaning plate 87 is fixedly installed on the other end of the thin cylinder 83, and a round opening 88 is opened on the outer side of the cleaning plate 87, the thick cylinder 81, the thick spring 82, the thin cylinder 83, the thin spring 84, the hinge block 85, the round ball 86, and the cleaning plate 87 and the round mouth 88 are provided with multiple groups, and multiple groups of thick cylinders 81, thick springs 82, thin cylinders 83, thin springs 84, hinged blocks 85, balls 86 and round mouths 88 are arranged in a linear array at equal intervals on the outside of the cleaning plate 87, and multiple groups of thick cylinders 81, thick springs 82, thin cylinders 83, thin springs 84, hinged blocks 85, balls 86, cleaning plates 87 and round mouths 88 are mirrored on the inner side of the outer shell 1 with the vertical center line of the front-to-back direction of the outer shell 1 as the mirror axis, and the mirror image is arranged on the inner side of the outer shell 1, multiple groups of thin cylinders 83 slide on the inner side of the thick cylinder 81, the hinged block 85 slides inside the thin cylinder 83, the ball 86 is arranged on the inner side of the round mouth 88, the outer side of the cleaning plate 87 is arc-shaped, and the outer side of the cleaning plate 87 is in contact with the surface of the filter cartridge 69.

[0042] When the present embodiment is used, in a natural state, the coarse spring 82 and the fine spring 84 are in a certain compression or tension state, so that the outer side of the cleaning plate 87 is in contact with the surface of the filter cartridge 69. When impurities accumulate on the surface of the filter cartridge 69 or the shape changes slightly, due to the structure of the hinge block 85 and the ball 86, the cleaning plate 87 can flexibly adjust its position within a certain range. The ball 86 is located in the circular opening 88 on the outer side of the cleaning plate 87. The hinge block 85 can slide inside the fine cylinder 83, and the fine cylinder 83 can slide inside the coarse cylinder 81. This structure enables the cleaning plate 87 to adapt to the surface condition of the filter cartridge 69 and always maintain a close fit with the filter cartridge 69. At the same time, when the filter cartridge 69 rotates, the cleaning plate 87, under the action of the coarse spring 82 and the fine spring 84, scrapes and cleans the surface of the filter cartridge 69 to remove impurities on the surface of the filter cartridge 69. The cleaning action of the cleaning plate 87 can prevent impurities from accumulating on the surface of the filter cartridge 69, avoid excessive accumulation of impurities affecting the filtering effect of the filter cartridge 69, ensure the normal operation of the filter cartridge 69, and maintain the stable performance of the entire pressure relief system.

[0043] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
