Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grease conveying technology, specifically relating to a grease pressure stabilizing mechanism. Background Technology
[0002] Grease transport is a key link in grease processing and industrial applications, mainly involving closed transport, special equipment and technical characteristics. Grease pumps are used in the grease transport process.
[0003] However, the grease pressure reducing valve in a traditional grease pump cannot accurately stabilize the oil pressure, which may result in uneven oil supply to various lubrication points, leading to insufficient or excessive lubrication.
[0004] Therefore, a grease pressure stabilizing mechanism is proposed. Utility Model Content
[0005] This invention provides a grease pressure stabilizing mechanism, the purpose of which is to solve the problems mentioned above.
[0006] This utility model embodiment provides a grease pressure stabilizing mechanism, including a cavity, an oil chamber inside the cavity, and an on / off valve on the cavity. The on / off valve includes a valve body on one outer wall of the cavity, a cylinder one on one outer wall of the valve body, a valve cover on the other outer wall of the valve body, an oil pipe connector one on the outer wall of the valve body adjacent to the valve cover, a pin at the output end of the cylinder one, and a hydraulic direct interface inside the valve body. A cylinder two is located on the outer wall of the cavity adjacent to the valve body, and a pressure plate and a retaining ring are provided between the cavity and the cylinder two. The pressure plate is located on one side of the retaining ring, and a pipe connector is located on the outer wall of the cylinder two. A cover plate is located on the outer wall of the cavity adjacent to the valve body, and an oil pipe connector two and an extension connector are provided on the cover plate. The oil pipe connector two is located on one side of the extension connector.
[0007] Furthermore, both the second oil pipe joint and the extension joint are connected to the inside of the oil cavity through a cover plate; By adopting the above technical solution, the interconnected structure allows grease to pass sequentially through the oil pipe joint, on / off valve, and hydraulic direct interface, and finally enter the interior of the oil chamber.
[0008] Furthermore, the ejector pin is located directly above the hydraulic direct interface, and the ejector pin controls the on / off state of the hydraulic direct interface; By adopting the above technical solution, the on / off valve can be closed, thereby allowing the oil pressure in the oil chamber to be at a higher pressure value.
[0009] Furthermore, both the oil pipe joint and the oil cavity are connected to the hydraulic direct interface; By adopting the above technical solution, the oil can be output smoothly, achieving a stable pressure state.
[0010] The beneficial effects of this utility model are as follows: This invention achieves stable and constant grease output pressure through the pressure stabilizing mechanism, thereby ensuring precise and equal oil supply to each lubrication point of the product and avoiding problems of insufficient or excessive lubrication.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0013] Reference Figure 1-2This utility model embodiment proposes a grease pressure stabilizing mechanism, including a cavity 1, an oil chamber 2 inside the cavity 1, and an on / off valve on the cavity 1. The on / off valve includes a valve body 3 on one outer wall of the cavity 1, a cylinder 4 on one outer wall of the valve body 3, and a valve cover 5 on the other outer wall of the valve body 3. An oil pipe connector 6 is provided on the outer wall of the valve body 3 adjacent to the valve cover 5. The oil pipe connector 6 and the oil chamber 2 are both connected to a hydraulic direct interface 8. Through the connected structure, grease can pass through the oil pipe connector 6, the on / off valve, and the hydraulic direct interface 8 in sequence, and finally enter the interior of the oil chamber 2. A pin 7 is provided at the output end of the cylinder 4. The hydraulic direct interface 8 is provided inside the valve body 3. The pin 7 is located directly above the hydraulic direct interface 8, and the pin 7 controls the on / off of the hydraulic direct interface 8, which can realize the closure of the on / off valve, thereby allowing the oil pressure in the oil chamber 2 to be in a higher pressure value state. A cylinder 10 is provided on the outer wall of the cavity 1 adjacent to the valve body 3. A pressure plate 9 and a retaining ring 11 are provided between the cavity 1 and the cylinder 10. The pressure plate 9 is located on one side of the retaining ring 11. The pressure plate 9 and the retaining ring 11 ensure the sealing of the connection between the cavity 1 and the cylinder 10, thereby ensuring the sealing of the output end of the cylinder 10 within the oil cavity 2 and preventing grease leakage. A pipe joint 15 is provided on the outer wall of the cylinder 10. Compressed gas is provided to the cylinder 10 through the pipe joint 15, thereby allowing the output end of the cylinder 10 to move. A cover plate 12 is provided on the outer wall of the cavity 1 adjacent to the valve body 3. An oil pipe connector 2 13 and an extension connector 14 are provided on the cover plate 12. The oil pipe connector 2 13 is located on one side of the extension connector 14. Both the oil pipe connector 2 13 and the extension connector 14 are connected to the inside of the oil cavity 2 through the cover plate 12, which allows the grease to be output smoothly and achieve a stable pressure state. Specifically, first control cylinder 2 10 to make its output end enter the oil chamber 2 in the cavity 1, and then the external grease pump injects oil into the pressure stabilizing mechanism in this embodiment. When injecting grease into the oil chamber 2, connect oil pipe joint 1 6 to the external grease pump. The grease passes through oil pipe joint 1 6, on / off valve and hydraulic direct interface 8 in sequence, and finally enters the interior of oil chamber 2. After the grease injection is completed, the on / off valve immediately closes the inlet. When closing the inlet, the control cylinder 4 drives the ejector pin 7 to move through its output end on one side. The ejector pin 7 moves above the hydraulic direct interface 8 and blocks the hydraulic direct interface 8, thus closing the on / off valve. After the grease is injected into the oil chamber 2, the oil pressure in the oil chamber 2 increases. The increased oil pressure pushes the output end of the cylinder 10 to reset. At this time, the gas in the cylinder 10 is compressed. The compressed air is used as a power source to smoothly output the grease in the oil chamber 2. Opening the oil pipe joint 13 and the extension joint 14 allows the grease in the oil chamber 2 to be pushed out, thus achieving pressure stabilization of the grease during the transportation process.
