Description

Technical Field

[0001] The present invention relates to the technical field of a plunger structure for reducing the probability of clogging in grease distribution valves. Background Technology

[0002] Currently used grease distribution valves mainly consist of a valve body and a plunger. Grease drives the plunger to move, thus completing the grease distribution function. The plunger's main structure is stepped; grease pushes the plunger's end face and the steps, causing the plunger to move. In this plunger technology, if the grease does not move for a long time (when the pump is stopped), due to the stepped structure, the grease tends to accumulate at the plunger steps, forming a solid state. This blocks the gap between the distribution valve and the plunger, preventing the plunger from being pushed and causing the distribution valve to become clogged.

[0003] Therefore, how to solve the problem of easy clogging of existing distribution valves is a technical problem that urgently needs to be solved. Utility Model Content

[0004] In view of this, the present invention provides a plunger structure for reducing the probability of clogging of grease distribution valves. It changes the transition method at different diameters of the plunger, changing the original stepped shape (right angle mode) to an inclined shape (oblique angle mode), making the transition method between different diameters of the plunger more rounded and simple.

[0005] The plunger structure provided by this utility model for reducing the probability of clogging in grease distribution valves adopts the following technical solution:

[0006] A plunger structure for reducing the probability of clogging in grease distribution valves includes a plunger shaft, a plunger tube coaxially disposed on the outer contour of the plunger shaft, an oil passage formed between the plunger shaft and the plunger tube, and a chamfer is provided at the end of the plunger tube where it connects to the outer contour of the plunger shaft, through which grease flows through the plunger shaft.

[0007] Optionally, the plunger tubes are disposed on both sides of the plunger shaft along the length of the plunger shaft.

[0008] Optionally, a separator pipe is provided between the two plunger tubes on the plunger shaft, the separator pipe being used to separate the oil passage along the length of the plunger shaft.

[0009] Optionally, the plunger tube is provided with chamfers on both sides along the length of the plunger shaft.

[0010] Optionally, the separator tube is provided with a chamfer two along the length direction of the plunger shaft.

[0011] Optionally, both chamfer one and chamfer two are straight bevel chamfers.

[0012] Optionally, the angle range of chamfer one and / or chamfer two is 15°-65°.

[0013] In summary, this utility model has at least one of the following beneficial technical effects: the structure is simple and highly operable; the chamfer can effectively reduce the risk of blockage of the distribution valve; it is economical and affordable; it improves the working efficiency of the lubrication system and reduces maintenance costs.

[0017] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0018] The following is in conjunction with the appendix Figure 1 The present invention will be described in further detail below.

[0019] This utility model discloses a plunger structure for reducing the probability of clogging in grease distribution valves.

[0020] Reference Figure 1 A plunger structure for reducing the probability of grease distribution valve blockage includes a plunger shaft 1, a plunger tube 2 coaxially arranged on the outer contour of the plunger shaft 1, forming an oil channel between the plunger shaft 1 and the plunger tube 2, and a chamfer 3 provided at the connection between the end of the plunger tube 2 and the outer contour of the plunger shaft 1. Grease flows through the plunger shaft 1 through the chamfer 3. This structure is simple, highly operable, and the chamfer can effectively reduce the risk of distribution valve blockage. It is economical, improves the working efficiency of the lubrication system, and reduces maintenance costs.

[0021] In this embodiment, two plunger tubes 2 are provided, spaced apart along the length of the plunger shaft 1, and located on both sides of the plunger shaft 1 along its length, forming two oil channels. In other embodiments, multiple plunger tubes can be provided, forming multiple oil channels.

[0022] A plunger shaft 1 is provided with a partition pipe 4 located between two plunger tubes 2. The partition pipe 4 is used to divide the oil passage along the length of the plunger shaft 1.

[0023] In this embodiment, chamfer 3 is provided on both sides of the plunger tube 2 along the length of the plunger shaft 1, and chamfer 5 is provided on the separator tube 4 along the length of the plunger shaft 1. In this embodiment, both chamfer 3 and chamfer 5 are straight bevel chamfers. The straight bevel chamfers can effectively prevent grease from adhering to the plunger without obstructing the normal flow of oil, thereby reducing the solidification of grease after it adheres to the plunger and effectively reducing the probability of blockage of the distribution valve.

[0024] The angle range of chamfer 3 and / or chamfer 5 is 15°-65°. When it is within this angle range, it can effectively prevent grease from adhering to the plunger, thereby reducing the solidification of grease after it adheres to the plunger, and effectively reducing the probability of blockage of the distribution valve.

[0025] This invention changes the original right-angle transition to an oblique transition in the transition area between the plunger shaft 1 and the plunger tube 2, making the transition method smoother and simpler. When the distribution valve is not in operation for a long time, grease is less likely to adhere to the plunger (there is no right-angle step), thereby reducing the solidification of grease after it adheres to the plunger and effectively reducing the probability of the distribution valve becoming blocked.

[0026] This invention has a simple structure, is economical and reliable, and is easy to implement. By changing the shape of the plunger, it effectively reduces the risk of blockage in the distribution valve.

[0027] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. The above descriptions are only preferred embodiments of this utility model. It should be noted that due to the limitations of textual expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this utility model, and can also combine the above technical features in an appropriate manner. These improvements, modifications, changes, or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without modification, should all be considered within the protection scope of this utility model.
