[0020] like Figure 1-5 As shown, a plate-type double-line distributor comprises a pump station 1, on which two groups of oil pipes 2 are fixedly arranged, and double-line distributors 3 are respectively installed on the two groups of oil pipes 2, and the double-line distributor 3 comprises a starting plate 31, one side of the starting plate 31 is provided with five groups of intermediate plates 32, one side of the intermediate plate 32 is provided with a termination plate 33, the inner sides of the starting plate 31, the intermediate plate 32 and the termination plate 33 are provided with a reversing valve core 34, one side of the starting plate 31, the intermediate plate 32 and the termination plate 33 is provided with an oil return port 35, the other side of the starting plate 31, the intermediate plate 32 and the termination plate 33 is provided with an oil inlet 36, and the upper ends of the starting plate 31, the intermediate plate 32 and the termination plate 33 are provided with a right An oil outlet 37, a left oil outlet 38 is provided on one side of the upper end of the starting piece 31, the middle piece 32, and the ending piece 33 corresponding to the oil inlet 36, a switch cabin 39 is provided inside the upper side of the starting piece 31, the middle piece 32, and the ending piece 33, and a switch valve core 310 is installed on the inner side of the switch cabin 39, a metering cabin 311 is provided inside the lower side of the starting piece 31, the middle piece 32, and the ending piece 33, and a metering valve core 312 is provided on the inner side of the metering cabin 311, the reversing valve core 34 includes an internal valve core oil channel 341, a connecting groove 342 is provided on the outer side of the reversing valve core 34, an annular groove 343 is provided on the upper side of the reversing valve core 34, and two groups of oil holes 344 are provided on the lower side of the reversing valve core 34.

[0021] In this embodiment, the double-line distributor 3 is composed of screws as a whole. The starting piece 31, five sets of intermediate pieces 32, and the ending piece 33 are rectangular blocks of different thicknesses. The switch valve core 310 is a cylindrical object. The switch valve core 310 slides left and right to open or close the passage between the metering cabin 311 and the right oil outlet 37 and the left oil outlet 38. The metering valve core 312 is a cylindrical object. The metering valve core 312 slides left and right to measure the oil output, which is determined by the length of the metering valve core 312. The two sets of double-line distributors 3 are in parallel relationship. The left double-line distributor 3 is connected in parallel. The line distributor 3 lubricates the friction surface at the bottom of the left side point rail of the railway and is connected one by one with the left oil channel of the left side slide bed plate of the railway, and the left oil outlet 38 discharges lubricating oil. A row of right oil outlets 37 of the right double-line distributor 3 are connected one by one with the right oil channel of the right side slide bed plate of the railway, and the right oil outlet 37 discharges lubricating oil. The reversing valve core 34 is connected to the switch machine through the connecting rod 313, and the two groups of annular grooves 343 are always connected with the valve core oil channel 341; the connecting groove 342 is always connected with the oil inlet 36, and the annular groove 343 is always connected with the oil return port 35.

[0022] Specifically, when the pointed rail moves to the left, the connecting rod 313 indirectly drives the reversing valve core 34 to deflect to the left. At this time, the pointed rail fits with the left basic rail, and the bottom of the pointed rail presses on the left oil outlet 38 of the sliding bed plate lubricating oil to discharge oil for lubrication; when the pointed rail moves to the right, the connecting rod 313 indirectly drives the reversing valve core 34 to deflect to the right. At this time, the pointed rail fits with the right basic rail, and the bottom of the rail presses on the right oil outlet 37 of the sliding bed plate lubricating oil to discharge oil for lubrication; and the oil enters the valve body from the oil inlet 36, and the oil outlet states of the right oil outlet 37 and the left oil outlet 38 are switched through the left and right deflections of the reversing valve core 34. Therefore, when the reversing valve core 34 deflects to the left, the oil inlet 36 is connected with the right cavity of the switch cabin 39, and the high-pressure oil enters the valve body from the oil inlet 36, and reaches the right cavity of the switch cabin 39 through the oil inlet passage, pushing the switch valve core 310 to move left, and the grease in the left cavity of the switch cabin 39 is pushed to the oil return port 3 5. Return to the oil tank. Under continuous oil pressure, the switch valve core 310 moves leftward continuously until it is connected with the right chamber of the metering cabin 311. At the same time, the left chamber of the metering cabin 311 is connected with the left oil outlet 38. The pressurized oil enters the right chamber of the metering cabin 311, pushing the metering valve core 312 to move leftward, and pushing the grease in the left chamber of the metering cabin 311 out of the left oil outlet 38. That is, when the reversing valve core 34 deflects to the left, oil flows out of the left oil outlet 38. Similarly, when the reversing valve core 34 deflects to the right, oil flows out of the right oil outlet 37. It can be seen that the oil is discharged on demand under the drive of the switch machine, the oil volume is controllable under the control of the metering cabin 311, and the right oil outlet 37 and the left oil outlet 38 are alternately discharged under the control of the reversing valve core 34. As the point rail moves left and right, the lubrication mode of regularly alternating oil discharge makes the device highlight its various advantages in the double-line lubrication system of the turnout and well meets the use requirements of the turnout lubrication system.

[0023] Working principle: when the pointed rail moves to the left, the connecting rod 313 indirectly drives the reversing valve core 34 to deflect to the left. At this time, the pointed rail fits with the left basic rail, and the bottom of the pointed rail presses on the left oil outlet 38 of the sliding bed plate lubricating oil to discharge oil for lubrication; when the pointed rail moves to the right, the connecting rod 313 indirectly drives the reversing valve core 34 to deflect to the right. At this time, the pointed rail fits with the right basic rail, and the bottom of the rail presses on the right oil outlet 37 of the sliding bed plate lubricating oil to discharge oil for lubrication; and the oil enters the valve body from the oil inlet 36, and the oil outlet states of the right oil outlet 37 and the left oil outlet 38 are switched through the left and right deflections of the reversing valve core 34. Therefore, when the reversing valve core 34 deflects to the left, the oil inlet 36 is connected with the right cavity of the switch cabin 39, and the high-pressure oil enters the valve body from the oil inlet 36, and reaches the right cavity of the switch cabin 39 through the oil inlet passage, pushing the switch valve core 310 to move left, and the grease in the left cavity of the switch cabin 39 is pushed to the oil return port 3 5. Return to the oil tank. Under continuous oil pressure, the switch valve core 310 moves leftward continuously until it is connected with the right chamber of the metering cabin 311. At the same time, the left chamber of the metering cabin 311 is connected with the left oil outlet 38. The pressurized oil enters the right chamber of the metering cabin 311, pushing the metering valve core 312 to move leftward, and pushing the grease in the left chamber of the metering cabin 311 out of the left oil outlet 38. That is, when the reversing valve core 34 deflects to the left, oil flows out of the left oil outlet 38. Similarly, when the reversing valve core 34 deflects to the right, oil flows out of the right oil outlet 37. It can be seen that the oil is discharged on demand under the drive of the switch machine, the oil volume is controllable under the control of the metering cabin 311, and the right oil outlet 37 and the left oil outlet 38 are alternately discharged under the control of the reversing valve core 34. As the point rail moves left and right, the lubrication mode of regularly alternating oil discharge makes the device highlight its various advantages in the double-line lubrication system of the turnout and well meets the use requirements of the turnout lubrication system.
