Description

Technical Field

[0001] The present application relates to the field of distributors, and in particular to a single-line distributor. Background Art

[0002] Good lubrication between relatively moving parts is very important. Once the grease cannot reach the lubrication part on time and in a certain amount, dry friction will occur between the moving parts, accelerating the wear between the mating surfaces and causing high temperature effects, which may damage the parts or even cause the equipment to be scrapped. The grease in the centralized lubrication system reaches each lubrication part through the distributor along the pipeline, so the distributor plays a pivotal role in the centralized lubrication system. It distributes the pressure grease delivered by the oil pump according to the amount of oil required by each lubrication point, and requires accurate delivery to the lubrication position.

[0003] At present, a Chinese invention patent with publication number CN117167641A discloses an integral oiler, including a valve body, an oil inlet connector for adding lubricating oil and an oil inlet channel connected to the oil inlet connector, a plurality of oil storage components connected in parallel are symmetrically arranged on both sides of the oil inlet channel, the oil storage components are used to store lubricating oil when the oiler is pressurized and to discharge the lubricating oil when the pressure is relieved, a plurality of oil outlet components connected in parallel are symmetrically arranged on both sides of the oil inlet channel, the oil storage components and the oil outlet components are arranged in one-to-one correspondence, and the oil outlet components are used to discharge the lubricating oil discharged from the oil storage components when the oiler is depressurized; the fully parallel structure of the invention realizes a single-point independent oil supply mode.

[0004] The existing oil storage assembly uses a spring to discharge the lubricating oil in a pressure relief state. When the pressure at the lubrication point of the equipment connected to the oil storage assembly is greater than the elastic force of the spring in the oil storage assembly, the oil storage assembly cannot discharge the lubricating oil smoothly, resulting in the distributor being unable to operate smoothly and the applicability of the distributor is not strong. Summary of the invention

[0005] In order to enable the distributor to be connected to equipment with different pressures and to discharge lubricating oil smoothly, thereby improving the applicability of the distributor, the present application provides a single-line distributor.

[0006] The present application provides a single-line distributor, which adopts the following technical solution: 14. The oil distribution device of claim 13, wherein the control unit comprises an oil storage assembly and an oil outlet assembly, wherein the valve body is provided with an oil inlet channel and an oil outlet channel, the oil inlet channel is communicated with the oil outlet channel, the oil storage assembly comprises an oil storage cover and a control board, the oil storage cover and the valve body form a bin body for storing oil, the control board is slidably connected to the bin body and divides the bin body into an oil storage bin and an oil outlet bin, the oil storage bin is communicated with the oil inlet channel, the oil outlet bin is communicated with the oil outlet channel, the oil outlet assembly is used to control the flow direction of lubricating oil, when the valve body is in a boosting state, the oil outlet assembly blocks the oil outlet channel and guides the lubricating oil into the oil storage bin, when the valve body is in a pressure relief state, the oil outlet assembly is used to guide the lubricating oil in the oil storage bin into the oil outlet bin, and when the subsequent valve body enters the boosting state again, the control board pumps the lubricating oil in the oil outlet bin away from the oil outlet channel.

[0007] When the pressure in the oil tank is too high, the oil level in the oil outlet pipe increases, and the oil pressure in the oil outlet pipe increases, so that the oil pressure in the oil tank increases, and the oil level in the oil outlet pipe increases. When the pressure in the oil tank is too high, the oil level in the oil outlet pipe increases, and the oil pressure in the oil outlet pipe increases. When the pressure in the oil tank is too high, the oil level in the oil outlet pipe increases, and the oil level in the oil outlet pipe increases. When the pressure in the oil tank is too high, the oil level in the oil outlet pipe increases, and the oil level in the oil outlet pipe increases.

[0008] Optionally, the oil storage assembly also includes a return spring and a sealing ring, and the sealing ring is arranged on the control panel. When the valve body is in a pressure relief state, after the oil outlet assembly blocks the oil inlet channel, the return spring is used to allow the lubricating oil in the oil storage tank to enter the oil outlet tank through the oil inlet channel.

[0009] By adopting the above technical solution, since the control board needs to slide in the bin body, the sealing ring is arranged on the control board to improve the sealing effect of the oil storage bin and the oil outlet bin, reduce the circulation of lubricating oil in the oil storage bin and the oil outlet bin without passing through the oil outlet component, and improve the reliability of the distributor; when the valve body is in the pressure relief state, as the pressure in the oil outlet bin gradually recovers, the control board moves, and the volume of the oil storage bin is reduced. During this period, only a part of the lubricating oil will enter the oil outlet bin through the oil storage bin and the time is relatively long. After adding a reset spring, the reset spring is in the original length state. The volume of the oil storage tank is much smaller than that of the oil outlet tank. When the distributor is in the boosted state, the lubricating oil enters the oil storage tank, and the volume of the oil storage tank gradually increases. The return spring is compressed by force, and the pressure in the oil outlet tank also increases accordingly. When the distributor is in the pressure relief state, the oil outlet assembly connects the oil outlet channel with the oil storage tank, and the return spring drives the control panel to move, and the pressure of the oil outlet tank acts on the lubricating oil in the oil storage tank at the same time, and the lubricating oil can smoothly enter the oil outlet tank. The return spring increases the movement speed of the lubricating oil and the amount of lubricating oil entering the oil outlet tank.

[0010] Optionally, the oil storage assembly also includes an observation piece that facilitates staff to observe the operation of the control unit, the observation piece includes a visual indicator rod and a matching sealing ring, the visual indicator rod is arranged on the control panel, the visual indicator rod passes through the oil storage cover, the matching sealing ring is arranged on the oil storage cover, and the matching sealing ring abuts against the visual indicator rod.

[0011] By adopting the above technical solution, since the interior of the distributor is in a sealed state, it is difficult for the staff to directly observe whether the control unit is transporting the lubricating oil normally. The observation piece makes it easy for the staff to observe whether the control unit is working normally. When the distributor is in a boost state, the lubricating oil enters the oil storage tank. When the distributor is in a pressure relief state, the lubricating oil is guided to the oil outlet tank through the oil outlet assembly. During this process, the control panel will move within the tank body, and the control panel will drive the visual indicator rod to move. Since the visual indicator rod passes through the valve body, it is easy for the staff to understand the working condition of the distributor. Since the visual indicator rod passes through the valve body, the sealing ring is used to improve the sealing effect between the visual indicator rod and the distributor, reduce the lubricating oil flowing out of the distributor with the movement of the visual indicator rod, and improve the reliability of the observation piece.

[0012] Optionally, the distribution column slides and circumferentially abuts the oil inlet channel, an oil inlet groove connected to the oil inlet channel is provided at one end of the distribution column, a first through hole connected to the oil inlet groove is provided on the distribution column, an oil outlet groove connected to the oil outlet channel is provided at one end of the distribution column, a second through hole connected to the oil outlet groove is provided on the distribution column, when the valve body is in a boosting state, the first through hole is connected to the oil storage tank; when the valve body is in a pressure relief state, the second through hole is connected to the oil storage tank.

[0013] By adopting the above technical scheme, when the distributor is in a boosting state, the lubricating oil enters the oil inlet groove, and the lubricating oil pushes the distribution column to move until the first through hole is connected with the oil storage tank, and the lubricating oil enters the oil storage tank through the oil inlet groove and the first through hole in sequence; when the distributor is in a pressure relief state, the distribution column moves under the action of negative pressure until the second through hole is connected with the oil storage tank, and under the action of the oil outlet tank pressure recovery and the reset spring, the lubricating oil enters the oil outlet tank through the second through hole, the oil outlet groove, and the oil outlet channel; the distribution column has a reasonable structure and is used to change the flow direction of the lubricating oil when the distributor is in different states.

[0014] Optionally, the oil outlet assembly further includes a valve core spring, and the valve core spring is used to drive the distribution column to move, and the elastic coefficient of the valve core spring is greater than the elastic coefficient of the return spring.

[0015] By adopting the above technical solution, the valve core spring is used for the rapid return of the distribution column. When the distributor is in a boosted state and the pressure of the lubricating oil on the distributor is greater than the elastic force of the valve core spring, the distributor moves so that the first through hole is connected to the oil storage tank; when the distributor is in a depressurized state, since the elastic coefficient of the valve core spring is greater than the elastic coefficient of the return spring, the valve core spring moves before the return spring, so the second through hole is connected before the oil storage tank, and under the action of the return spring, the lubricating oil enters the oil outlet channel and the oil outlet tank through the second through hole, and the structure of the oil outlet component is more reasonable.

[0016] Optionally, a one-way valve is provided in the oil outlet channel, and the one-way valve includes a valve seat and a rubber ring. The valve seat is located in the oil outlet channel, and the valve seat is truncated cone-shaped. The diameter of the valve seat gradually decreases along the flow direction of the lubricating oil. A through groove is provided at the large end of the valve seat, and a connecting hole is provided on the side wall of the valve seat. The connecting hole is connected with the through groove, and the rubber ring is sleeved on the valve seat, and the rubber ring covers the connecting hole.

[0017] By adopting the above technical scheme, the lubricating oil in the equipment will abut against the rubber ring, the rubber ring will cover the connecting hole, and the one-way valve reduces the backflow of the lubricating oil in the equipment into the distributor. When there is lubricating oil in the oil outlet bin and the distributor is in a boosted state, the lubricating oil in the oil outlet bin moves toward the equipment in the oil outlet channel under the drive of the control board. When passing through the one-way valve, it passes through the through groove and the connecting hole in turn, and pushes the rubber ring away from the connecting hole. The frustum provides a deformation range for the rubber ring, reduces the deformation of the rubber ring and abuts against the oil outlet channel, and the lubricating oil enters the equipment for lubrication. The reverse valve has a simple and reasonable structure.

[0018] Optionally, an annular groove is provided on the valve seat, and the rubber ring is located in the annular groove.

[0019] By adopting the above technical solution, after the lubricating oil flows out of the one-way valve, the annular groove is used to limit the position of the rubber ring, and the annular groove reduces the displacement of the rubber ring relative to the displacement valve seat, thereby improving the reliability of the one-way valve.

[0020] Optionally, a plurality of control units are provided on the valve body, a plurality of oil outlet channels are opened on the valve body, the plurality of oil outlet channels correspond one-to-one to a plurality of control units, and the control units control the oil outlet of the corresponding oil outlet channels.

[0021] By adopting the above technical solution and several control units, a single distributor can perform lubrication operations on multiple devices, and the failure of a single control unit will not affect the normal operation of other control units.

[0022] Optionally, the valve body is provided with a splicing piece for being connected in series with an adjacent valve body, the splicing piece includes a splicing plate and bolts, the splicing plate is provided on the valve body, and the bolts pass through the splicing plate and are threadedly connected to the adjacent valve body.

[0023] By adopting the above technical solution, the staff can adjust the number of valve bodies according to the number of equipment to be lubricated, thereby improving the application range of the distributor.

[0024] Optionally, the splicing part also includes a splicing tube, which is arranged on the valve body, the splicing tube is connected to the oil inlet channel, a matching groove is opened on the other side of the valve body, the matching groove is connected to the oil inlet channel, and the splicing tube is snap-fitted with the matching groove of the adjacent valve body.

[0025] By adopting the above technical solution, the splicing tube is snap-fitted with the matching groove of the adjacent valve body, which is used to improve the sealing effect of the adjacent valve bodies, reduce the outflow of lubricating oil from between the adjacent valve bodies, and make the structure more reasonable.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The oil storage cover and the valve body form a tank for storing oil. The control panel in the tank is divided into an oil storage tank and an oil outlet tank. The distributor can guide the lubricating oil into the oil storage tank or the oil outlet tank, so that the distributor can smoothly pump the lubricating oil into the equipment with pressure; 2.
