Description

Technical Field

[0001] The utility model relates to the technical field of flow control devices, in particular to a flow control device for an intelligent lubrication system. Background Art

[0002] The lubrication system refers to the delivery structure that delivers lubricating grease to the target node. The lubrication is delivered from the storage tank to the corresponding position through the pipeline. It is also one of the commonly used automatic lubrication methods in current machinery. This can avoid the tediousness of manual lubrication and does not require shutdown, which can effectively improve the high-frequency operation rate of the equipment.

[0003] However, current lubrication system pipelines are all straight-through pipes, and the flow rate cannot be adjusted according to needs. When lubrication continues, failure to add lubricating oil in time can easily cause production accidents. When lubrication is not required, continuous large-scale addition of lubricating oil will cause overflow, resulting in waste of lubricating oil. For this reason, a flow control device is set up.

[0009] The utility model has the following advantages: when a large amount of lubricating oil is needed, the pressure in the pipeline will increase, and the pressure will push the lifting plate outward, thereby simultaneously pushing the vertical rod outward, thereby driving the telescopic rod and the follower rod to be simultaneously pushed outward, thereby pulling the adjustment plate upward, and as the adjustment plate is raised and lowered, the distance between the adjustment plate and the inner wall of the pipeline can be adjusted, thereby adjusting the flow rate of the lubricating oil and realizing flow control.

DETAILED DESCRIPTION

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] Please refer to Figure 1-3 The utility model discloses a flow control device for an intelligent lubrication system, comprising a pipeline 1, a booster box 2 is fixedly connected to the top side wall of the pipeline 1, a control valve 6 is detachably connected to the pipeline 1 through a flange, a vertical rod 3 is telescopically inserted in the booster box 2, a telescopic rod 4 is telescopically inserted in the vertical rod 3, the telescopic rod 4 is a U-shaped structure, a through hole is formed through the top side wall of the control valve 6, and a follower rod 7 is telescopically inserted in the inner side of the through hole, and an end of the follower rod 7 located in the control valve 6 is fixedly connected to an adjusting plate 9;

[0016] One end of the vertical rod 3 located in the pipeline 1 is fixedly connected to a lifting plate 8, and the lifting plate 8 is an arc-shaped structure. The end of the telescopic rod 4 away from the vertical rod 3 is fixedly connected to a clamping plate 5, and the clamping plate 5 is detachably clamped on a section of the follower rod 7 close to the control valve 6. The adjusting plate 9 is a rectangular structure, and the end of the adjusting plate 9 away from the follower rod 7 is an arc-shaped structure and fits against the inner wall of the pipeline 1. The width of the adjusting plate 9 is the same as the through hole. The outer wall of the adjusting plate 9 is fixedly connected to a sealing rubber sleeve, and the rubber sleeve fits against the inner wall of the through hole.

[0017] The technical effect of this scheme is as follows: when a large amount of filling is required, the oil discharge rate of the oil storage tank is increased, thereby increasing the flow rate of the lubricating oil in the pipeline 1. As the flow rate increases, the pressure in the pipeline 1 will increase. The pressure increase can push the booster box 2 upward through the lifting plate 8, and in this way, the follower rod 7 is driven to lift upward, thereby driving the adjusting plate 9 to rise synchronously, thereby increasing the distance between the adjusting plate 9 and the inner wall of the pipeline 1, thereby increasing the flow rate. When lubrication is required for low-flow delivery, the pressure in the pipeline 1 will be reduced, causing it to drop under the drive of the spring 12, thereby driving the adjusting plate 9 to drop synchronously to reduce the distance between the adjusting plate 9 and the pipeline 1, thereby reducing the flow rate. The entire process does not require electronic equipment control and is adaptively adjusted according to the pressure in the pipeline 1.

[0018] An inner groove 10 is provided inside the booster box 2, and the opposite side walls in the inner groove 10 are fixedly connected with a fixing plate 11, and the bottom side wall of the fixing plate 11 is fixedly connected with a spring 12, and the end of the spring 12 away from the fixing plate 11 is fixedly connected with a connecting plate 13, and the connecting plate 13 is fixedly connected to the outer wall of the vertical rod 3 at one end located in the inner groove 10, and one side wall inside the vertical rod 3 is evenly provided with a card groove 16, the telescopic rod 4 is located in the vertical rod 3 and the side wall opposite to the card groove 16 is fixedly connected with a V-shaped elastic member 14, and the outer wall of the end of the elastic member 14 close to the card groove 16 is fixedly connected with a card block 15, and the card block 15 is connected to the card groove 16, and the card block 15 and the card groove 16 are both conical structures.

[0019] The technical effect of this solution is as follows: in order to avoid the booster box 2 from rising and falling randomly, the spring 12, the connecting plate 13 and the elastic member 14 are set to increase the pressure to ensure the overall stability. At the same time, the position of the vertical rod 3 can be limited to ensure the minimum distance between the adjustment plate 9 and the pipeline 1, thereby ensuring that the lubricating oil can always be delivered and output, ensuring the minimum real-time lubrication function. In order to further improve the lifting and lowering adjustment range of the adjustment plate 9, the height of the telescopic rod 4 is adjusted by the elastic member 14, the slot 16 and the block 15. After adjusting to the appropriate position, the splint 5 is connected to the corresponding position of the follower rod 7. The different positions of the splint 5 on the follower rod 7 can realize the kinetic energy of different adjustment ranges of the adjustment plate 9, thereby increasing the flexibility and practicality of the application.

[0020] Specifically, when the utility model is used, the flow rate of the lubricating oil in the pipeline 1 is adjusted by the pump machine connected to the oil storage tank, so as to control the pressure in the pipeline 1. When a large flow of lubricating oil circulates in the pipeline 1, the internal pressure thereof will naturally increase, and the high pressure generated will push the lifting plate 8 upward, thereby driving the vertical rod 3 and the telescopic rod 4 to rise synchronously, and at the same time driving the follower rod 7 and the adjusting plate 9 to rise synchronously, thereby increasing the distance between the adjusting plate 9 and the pipeline 1, thereby realizing the function of increasing the flow rate. When the flow rate of the lubricating oil in the pipeline 1 decreases, the pressure will also decrease synchronously, and the adjusting plate 9 will be driven to decrease synchronously by the deadweight of the spring 12 and the lifting plate 8, thereby reducing the flow rate. The lifting and lowering activities of the adjusting plate 9 can be automatically controlled according to the actual flow rate, thereby realizing the function of adaptive flow rate adjustment, and the function of driving the clamping plate 5 to be connected to different positions on the follower rod 7 by adjusting the height of the telescopic rod 4 itself, thereby increasing the range of the lifting and lowering adjustment of the adjusting plate 9, thereby increasing the usability and application flexibility of the equipment.

It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
