Description

Technical Field

[0001] This utility model relates to the field of oil output monitoring technology, and in particular to a single-line dynamic monitoring distributor. Background Technology

[0002] In industrial fields such as lubrication and hydraulic transmission, accurate and reliable quantitative distribution of grease or lubricating oil is crucial, directly affecting the service life and operational stability of mechanical equipment. Multi-line distribution systems require independent pipelines and control valves for each lubrication point, resulting in large systems, complex installation and maintenance, and high costs.

[0003] Traditional single-line or progressive distributors are mostly purely mechanical structures, which cannot monitor in real time whether each oil outlet is discharging oil normally. Equipment managers can only discover the problem through periodic inspections or when the equipment fails due to poor lubrication. This leads to delayed maintenance and can easily cause unexpected downtime and production losses. Therefore, those skilled in the art have provided a single-line dynamic monitoring distributor to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a single-line dynamic monitoring distributor that retains the advantages of a single-line system. Grease enters through a single inlet port and is distributed to each outlet port through an internal valve core and piston structure, greatly simplifying the pipeline layout and enabling on / off control of the oil circuit, which is the basis for its efficient distribution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a single-line dynamic monitoring distributor, including a valve body, a valve hole is provided at the center of the front end face of the valve body, a switch valve core is provided inside the valve hole, a reset structure is threaded inside the valve hole at the front end of the switch valve core, and metering chambers are provided at the front of both the upper and lower ends of one side wall of the valve body, and first oil passages are provided at the center of the lower inner wall of the two metering chambers at the upper end and the center of the upper inner wall of the two metering chambers at the lower end;

[0006] The switching valve core includes a valve core body. A first valve core oil passage is provided at the center of the rear end face of the valve core body. A third oil passage is provided at the center of the upper and lower end faces of the first valve core oil passage. A second valve core oil passage is provided at the center of the front inner wall of the first valve core oil passage. A fourth oil passage is provided at the front of the upper and lower inner side walls of the second valve core oil passage. Two annular grooves are arranged in a front-to-back pattern on the outer side wall of the valve core body.

[0007] Through the above technical solution, the two third oil passages and two fourth oil passages on the valve core body are connected to the four first oil passages. The grease at the oil inlet continuously enters the four metering chambers through the first valve core oil passage, the second valve core oil passage, the third oil passage, the fourth oil passage and the first oil passage until the metering chambers are full, and oil control is achieved in combination with the metering structure.

[0008] Furthermore, the distance between the two annular grooves is the same as the distance between the two first oil passages at the front and the two first oil passages at the rear.

[0009] The above technical solution facilitates the connection between the two first oil passages and the second oil passage through the two annular grooves.

[0010] Furthermore, the reset structure includes a connecting seat, which is fixedly sleeved on the front side of the outer wall of the valve core body. A first spring is fixedly connected to the front end face of the connecting seat. A limiting shell is sleeved on the outer side of the first spring and the connecting seat. The front end of the first spring is fixedly connected to the front inner wall of the limiting shell. The rear end of the limiting shell is threadedly connected to the front part of the valve hole.

[0011] Through the above technical solution, under the push of oil pressure, the valve core body squeezes the connecting seat to move into the inner limit shell, and squeezes the first spring to move forward to the limit. When the main pipeline oil pressure rises to the set value, a signal is fed back to the control terminal, and then the pump stops and is unloaded. The main pipeline oil pressure drops, and the tension of the first spring pushes the connecting seat and the valve core body to move backward and reset.

[0012] Furthermore, through holes are provided at the center of the inner wall of the two upper metering chambers and at the center of the lower end face of the two lower metering chambers. Each of the four through holes is provided with a contact assembly. Taking the upper front contact assembly as an example, the contact assembly includes a contact mounting base. A common end is fixedly connected to the center of the upper end face of the contact mounting base. Detection contacts are provided on the upper end faces of the contact mounting base at both ends of the common end. The two detection contacts and the lower end of the common end pass through the contact mounting base to both sides of the contact mounting base.

[0013] Through the above technical solution, the contact assembly mainly consists of a contact mounting base, a common terminal, and two detection contacts. The common terminal and the two detection contacts are conductive metal sheets, and the contact mounting base is made of insulating material, which forms an insulating isolation between the three contacts installed therein. The contact assembly is located in the middle of the metering chamber. During the oil storage and discharge process of the pistons on both sides, a switching signal is generated. The control terminal dynamically monitors the movement of the piston by detecting the switching signal, and then determines the oil discharge status of the oil outlet.

[0014] Furthermore, each of the four metering chambers is equipped with a metering structure. Taking one of the metering structures as an example, the metering structure includes two oil leakage seats. The two oil leakage seats are threaded to both ends of the metering chamber. Each of the two oil leakage seats has an oil outlet hole on its far side. Each of the two oil leakage seats has a second spring fixedly connected to its near side. Each of the two second springs has a column on its inner side. Each of the two columns has a piston fixedly connected to its near side. Each of the four metering chambers has two second oil passages arranged laterally on its inner wall near the valve hole. Eight second oil passages pass through the valve body and lead to the inner wall of the valve hole.

[0015] With the above technical solution, when the oil pressure in the main pipeline drops to a certain value, the control end restarts the oil pumping device to pump grease to the distributor. The continuously input high-pressure grease pushes the switch valve core forward to the limit again, fills the metering chamber again and pushes the piston, fills the metering chamber again and pushes the piston to move to both sides. The grease on the outside of the column is discharged from the oil outlet under the push of the piston, forming one oil discharge, and repeats in this way.

[0016] Furthermore, an oil inlet is fixedly connected to the rear end of the valve core body;

[0017] Through the above technical solution, the grease in the main pipeline enters the switching valve core from the oil inlet.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the device retains the advantages of a single-line system. Grease enters from a single oil inlet and is distributed to each oil outlet through the internal switch valve core and piston structure, which greatly simplifies the pipeline layout. Under the push of oil pressure, the switch valve core compresses the first spring and moves forward to the limit, realizing the on-off control of the oil circuit, which is the basis for its efficient distribution.

[0020] 2. In this utility model, the contact assembly is located in the middle of the metering chamber. During the oil storage and discharge process of the pistons on both sides, a switching signal is generated. The control end dynamically monitors the movement of the piston by detecting the switching signal, and then determines the oil discharge status of the oil outlet. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1-4 An embodiment of this utility model is provided: a single-line dynamic monitoring distributor, including a valve body 1, a valve hole 8 is provided at the center of the front end face of the valve body 1, a switch valve core 9 is provided inside the valve hole 8, a reset structure 3 is threaded inside the valve hole 8 at the front end of the switch valve core 9, and metering chambers 5 are provided at the front of both the upper and lower ends of one side wall of the valve body 1. A first oil passage 10 is provided at the center of the lower inner wall of the two upper metering chambers 5 and the center of the upper inner wall of the two lower metering chambers 5.

[0033] like Figure 2 , 3As shown in Figure 4, the switch valve core 9 includes a valve core body 901. A first valve core oil passage 902 is provided at the center of the rear end face of the valve core body 901. A third oil passage 903 is provided at the center of the upper and lower end faces of the first valve core oil passage 902. A second valve core oil passage 904 is provided at the center of the inner front wall of the first valve core oil passage 902. A fourth oil passage 905 is provided at the center of the upper and lower inner side walls of the second valve core oil passage 904. Two annular grooves 906 are arranged in a front-to-back pattern on the outer side wall of the valve core body 901. The two third oil passages 903 and the two fourth oil passages 905 on the valve core body 901 are connected to the four first oil passages 10. Grease from the oil inlet 7 continuously enters the four metering chambers 5 through the first valve core oil passage 902, the second valve core oil passage 904, the third oil passage 903, the fourth oil passage 905 and the first oil passage 10 until the metering chambers 5 are full. Combined with the metering structure 4, oil is controlled.

[0034] The distance between the two annular grooves 906 is the same as the distance between the two first oil passages 10 at the front and the two first oil passages 10 at the rear, which facilitates the connection between the two annular grooves 906 and the two first oil passages 10 and the second oil passage 11.

[0035] like Figure 1 , 2 As shown in Figure 3, the reset structure 3 includes a connecting seat 301, which is fixedly sleeved on the front side of the outer wall of the valve core body 901. A first spring 302 is fixedly connected to the front end face of the connecting seat 301. A limiting shell 303 is sleeved on the outer side of the first spring 302 and the connecting seat 301. The front end of the first spring 302 is fixedly connected to the front inner wall of the limiting shell 303. The rear end of the limiting shell 303 is threadedly connected to the front side of the valve hole 8. Under the push of oil pressure, the valve core body 901 squeezes the connecting seat 301 to move into the limiting shell 303, squeezing the first spring 302 to move forward to the limit. When the main pipeline oil pressure rises to the set value, a signal is fed back to the control end, and then the pump stops and is unloaded. The main pipeline oil pressure drops, and the tension of the first spring 302 pushes the connecting seat 301 and the valve core body 901 to move backward and reset.

[0036] Through holes 6 are provided at the center of the inner wall of the two upper metering chambers 5 and at the center of the lower end face of the two lower metering chambers 5. Each of the four through holes 6 is equipped with a contact assembly 2. Taking the upper front contact assembly 2 as an example, the contact assembly 2 includes a contact mounting base 201. A common end 202 is fixedly connected to the center of the upper end face of the contact mounting base 201. Detection contacts 203 are provided on the upper end faces of the contact mounting base 201 at both ends of the common end 202. The two detection contacts 203 and the lower end of the common end 202 respectively pass through the contact mounting base 201 and lead to the contact mounting base 201. On both sides of the mounting base 201, the contact assembly 2 mainly consists of a contact mounting base 201, a common end 202, and two detection contacts 203. The common end 202 and the two detection contacts 203 are conductive metal sheets, and the contact mounting base 201 is made of insulating material, which forms an insulating isolation for the three contacts installed therein. The contact assembly 2 is located in the middle of the metering chamber 5. During the oil storage and discharge process of the pistons 403 on both sides, a switching signal is generated. The control end dynamically monitors the movement of the pistons 403 by detecting the switching signal, and then determines the oil discharge status of the oil outlet.

[0037] like Figure 1 , 2 As shown in Figures 3 and 4, each of the four metering chambers 5 is equipped with a metering structure 4. Taking one of the metering structures 4 as an example, the metering structure 4 includes two oil leakage seats 401, which are threaded to both ends of the metering chamber 5. Each of the two oil leakage seats 401 has an oil outlet hole 402 on its far-away end face. A second spring 405 is fixedly connected to each of the two oil leakage seats 401 on its near-away end face. A column 404 is provided inside each of the two second springs 405. A piston 403 is fixedly connected to each of the two columns 404 on its near-away end face. The four metering chambers 5 are close to... Two second oil passages 11 are arranged laterally on the inner wall of the valve hole 8. The eight second oil passages 11 pass through the valve body 1 and lead to the inner wall of the valve hole 8. When the oil pressure in the main pipeline drops to a certain value, the control end restarts the oil pumping device to pump grease to the distributor. The continuously input high-pressure grease pushes the switch valve core 9 forward to the limit position, fills the metering chamber 5 again and pushes the piston 403. The metering chamber 5 is filled again and the piston 403 is pushed to move to both sides. The grease on the outside of the column 404 is discharged from the oil outlet 402 under the push of the piston 403, forming one oil discharge, and this process is repeated.

[0038] The valve core body 901 has an oil inlet port 7 fixedly connected to its rear end, and the grease in the main pipeline enters the switch valve core 9 from the oil inlet port 7.

[0039] Working principle: Grease from the main pipeline enters the switch valve core 9 through the oil inlet 7. Under oil pressure, the valve core body 901 squeezes the connecting seat 301 and moves it into the limiting housing 303, squeezing the first spring 302 forward to its limit. At this time, the two third oil passages 903 and two fourth oil passages 905 on the valve core body 901 are connected to the four first oil passages 10. Grease from the oil inlet 7 continuously enters the four metering chambers 5 through the first valve core oil passages 902, second valve core oil passages 904, third oil passages 903, fourth oil passages 905 and first oil passages 10 until the metering chambers 5 are full. At this time, it pushes the eight pistons 403 to move to both sides, squeezing the eight second springs 405. Compression causes the main pipeline oil pressure to rise. When the main pipeline oil pressure rises to the set value, a signal is fed back to the control terminal, and the pump stops and is unloaded. The main pipeline oil pressure drops, and the tension of the first spring 302 pushes the connecting seat 301 and the valve core body 901 to move backward and reset. At this time, the two annular grooves 906 on the valve core body 901 connect the eight second oil passages 11 with the four first oil passages 10. The tension of the eight second springs 405 on both sides pushes the eight pistons 403 to move towards the four contact plate assemblies 2. The grease in the four metering chambers 5 is squeezed and enters the metering chamber 5 outside the column 404 on one side of the piston 403 through the first oil passage 10, the annular groove 906 and the second oil passage 11.

[0040] When the oil pressure in the main pipeline drops to a certain value, the control end restarts the oil pumping device to pump grease to the distributor. The continuously input high-pressure grease pushes the switch valve core 9 forward to the limit position, fills the metering chamber 5 again, and pushes the piston 403. The metering chamber 5 is filled again and the piston 403 is pushed to move to both sides. The grease on the outside of the column 404 is discharged from the oil outlet 402 under the push of the piston 403, forming one oil discharge, and this process is repeated.

[0041] The contact assembly 2 mainly consists of a contact mounting base 201, a common terminal 202, and two detection contacts 203. The common terminal 202 and the two detection contacts 203 are conductive metal sheets, while the contact mounting base 201 is made of insulating material, providing insulation for the three contacts installed therein. The contact assembly 2 is located in the middle of the metering chamber 5. During the oil storage and discharge process of the pistons 403 on both sides, a switching signal is generated. The control terminal dynamically monitors the movement of the pistons 403 by detecting the switching signal, thereby determining the oil discharge status of the oil outlet. The insulation ensures that each detection contact 203 is electrically independent. The circuit is closed and a signal is generated only when the piston 403 contacts the detection contact 203. The control terminal continuously monitors the output of the contact assembly 2. When the detection contact 203 and the piston 403 are in contact and the circuit is closed, it indicates that the piston 403 has moved to its limit position. When the circuit is open, it indicates that the piston 403 is moving. The signal cycle is consistent with the preset oil discharge rhythm, indicating that the grease is successfully discharged from the oil outlet.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
