Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of intelligent centralized lubrication, and particularly relates to an oil liquid distribution device and an oil liquid distribution system. BACKGROUND

[0002] Intelligent centralized lubrication technology is a technology for automatically, regularly and quantitatively delivering lubricating oil to multiple lubrication points, and is widely used in industrial equipment, transportation tools (such as automobiles and trains) and heavy machinery.

[0003] In the intelligent centralized lubrication technology, the oil liquid distribution device is an important component. The conventional oil liquid distribution device is a linear motor push rod type oil liquid distribution device. Referring to the patent document with the announcement number CN207230135U, the linear motor push rod type oil liquid distribution device includes an electric quick on-off valve, a metering valve and an electric multi-way selection valve. The electric quick on-off valve and the electric multi-way selection valve each include a valve core, a valve body and a linear push rod motor. The valve core is movably installed in the valve body and includes a guide oil portion and a transmission portion connected to each other. The guide oil portion is movably installed in the valve body and is provided with an oil supply channel. The transmission portion is located outside the valve body. The linear push rod motor is connected to the guide oil portion through the transmission portion. The linear push rod motor can drive the guide oil portion to move linearly and reciprocally in the valve body, so that the oil supply channel can be in communication with a certain outlet on the valve body, thereby causing the oil liquid to flow from the outlet to the target lubrication point.

[0004] However, in the process of adjusting the oil outlet, the valve core needs to be repeatedly moved axially at a high frequency. Friction occurs continuously between the valve core and the sealing member and between the valve core and the valve body, resulting in the formation of an axial extension of the surface of the valve core and an abrasion mark extending from the valve body to the outside of the valve body. These axially extending abrasion marks can become leakage channels, causing the oil liquid to leak and the performance of the equipment using the linear motor push rod type oil liquid distribution device to be unable to be fully utilized.

[0046] Specifically, oil supply device can deliver oil liquid into first oil inlet flow passage 111 through ration supplier 2, and ration supplier 2 can make oil liquid from oil supply device ration delivery to first oil inlet flow passage 111 in unit time. The oil liquid that enters first oil inlet flow passage 111 can further enter the oil guide flow passage 121 of first valve core 12. First valve core 12 is arranged in first valve body 11, first drive motor 13 is installed in the outside of first valve body 11, and first drive motor 13 can drive first valve core 12 and rotate in first valve body 11. First valve core 12 selects the rotation angle of different, then the oil guide flow passage 121 of first valve core 12 can communicate with different first oil outlet flow passage 112, so that oil liquid can flow out from different first oil outlet flow passage 112.

At a certain position, only the first oil outlet hole 122 and the first first oil outlet flow channel 112 can be communicated (that is, other oil outlet holes 122 and other first oil outlet flow channels 112 are not communicated, and the following process is the same); the first valve core 12 is rotated by 90 degrees, only the second oil outlet hole 122 and the second first oil outlet flow channel 112 can be communicated; the first valve core 12 is rotated by 180 degrees, only the third oil outlet hole 122 and the third first oil outlet flow channel 112 can be communicated; the first valve core 12 is rotated by 270 degrees, only the fourth oil outlet hole 122 and the fourth first oil outlet flow channel 112 can be communicated.

[0059] As shown, Figure 9 In some embodiments of the utility model, the number of the first oil inlet flow channels 111 is two, and the dosing device 2 is configured to enable the oil liquid from the oil supply device to alternately flow to the two first oil inlet flow channels 111.

[0060] Specifically, the two first oil inlet flow channels 111 are respectively communicated with the oil guide flow channel 121. During the conveying of the oil liquid, the dosing device 2 can first make the dosing oil liquid flow to the first first oil inlet flow channel 111, and then make the dosing oil liquid flow to the second first oil inlet flow channel 111. In this way, the oil liquid alternately flows to one of the two first oil inlet flow channels 111, realizing the dosing and timing supply of the oil liquid.

[0061] In some embodiments of the utility model, the number of first oil inlet flow channels 111 is two, and the quantitative supply device 2 is configured to enable oil from the oil supply device to flow alternately to the two first oil inlet flow channels 111.

[0062] Specifically, during the conveying of oil, the quantitative supply device 2 can first enable the quantitative oil to flow to the first first oil inlet flow channel 111 and the first oil inlet groove 123, and then to the oil guide flow channel 121; and then enable the quantitative oil to flow to the second first oil inlet flow channel 111 and the second oil inlet groove 123, and then to the oil guide flow channel 121. In this way, the oil alternately flows through two oil paths into the oil guide flow channel 121, realizing the timed and quantitative supply of oil.

[0067] Specifically, for example, second drive motor 223 drives second valve core 222 to rotate, when the first first hole channel 221 rotates to the preset position, at this time, the first second oil inlet flow channel 211, the first first hole channel 221 and the first first oil guide channel 224 form an oil circuit (communication with the first oil injection space 234), and the oil flows to the second flow channel switching structure 23 through the oil circuit; and the second first hole channel 221 is not communicated. For another example, second drive motor 223 drives second valve core 222 to rotate, when the second first hole channel 221 rotates to the preset position, at this time, the second second oil inlet flow channel 211, the second first hole channel 221 and the second first oil guide channel 224 form an oil circuit (communication with the second oil injection space 235), and the oil flows to the second flow channel switching structure 23 through the oil circuit; and the first first hole channel 221 is not communicated.

[0068] Of course, the first flow channel switching structure 22 can also be other structures that can achieve the above technical effects, and the utility model does not limit.

[0069] In some embodiments, a second sealing ring is arranged around the end of the second valve core 222 and seals the second valve core 222. The second sealing ring is adjacent to the second drive motor 223.

The piston column 231 is installed in the fourth accommodating cavity and can move axially along the fourth accommodating cavity, the middle part of the piston column 231 is in sealing contact with the fourth peripheral wall, the leading end and the trailing end of the piston column 231 are respectively towards the first end wall and the second end wall, the first oil injection space 234 capable of accommodating oil is formed between the leading end of the piston column 231 and the first end wall, and the second oil injection space 235 capable of accommodating oil is formed between the trailing end of the piston column 231 and the second end wall. The second oil guiding channel 233 is arranged in the second valve body 21, and the two second oil guiding channels 233 are respectively communicated with the first oil injection space 234 and the second oil injection space 235. As shown Figure 14 As shown, the two second holes 232 are arranged in the second valve core 222 and extend radially through, the two first holes 221 are located between the two second holes 232, and the axes of the two second holes 232 are perpendicular to each other. The axis of the first hole 221 and the axis of the second hole 232 adjacent to the first hole 221 are perpendicular to each other; one end of the two second holes 232 respectively corresponds to one of the two second oil guiding channels 233, and the other end of the two second holes 232 respectively corresponds to one of the two second oil outlet flow channels 212. Based on the circumferential rotation of the second valve core 222, the two second holes 232 can alternately rotate into or rotate out of the position of making the corresponding second oil outlet flow channel 212 communicated with the second oil guiding channel 233. By being arranged in the above structure, the oil channel switching can be realized, the timed and quantitative supply of oil is facilitated, and the precision is higher.

[0071] Specifically, for example Figure 11 As shown, the second driving motor 223 drives the second valve core 222 to rotate, when the first first hole 221 rotates to the preset position, the first second oil inlet flow channel 211, the first first hole 221 and the first first oil guiding channel 224 form an oil circuit, and the oil can flow to the first oil injection space 234 through the oil circuit, so that the piston column 231 moves towards the second end wall and reduces the volume of the second oil injection space 235; at the same time, the second second hole 232 also rotates to the preset position, at this time, the second second oil guiding channel 233, the second second hole 232 and the second second oil outlet flow channel 212 form an oil circuit, and the oil in the second oil injection space 235 is driven by the piston column 231 to flow out of the oil circuit. For another example Figure 12As shown, the second driving motor 223 drives the second spool 222 to rotate, and when the second first hole 221 is rotated to a preset position, the second second oil inlet flow channel 211, the second first hole 221 and the second first oil guide channel 224 form an oil path, and the oil can flow to the second oil injection space 235 through the oil path, so that the piston column 231 moves towards the first end wall, and the volume of the first oil injection space 234 is reduced; at the same time, the first second hole 232 is also rotated to a preset position, and the first second oil guide channel 233, the first second hole 232 and the first second oil outlet flow channel 212 form an oil path, and the piston column 231 drives the oil in the first oil injection space 234 to flow out of the oil path.
