Description

Technical Field

[0001] The utility model relates to the technical field of rotary joints, in particular to a rotary distributor capable of adjusting flow rate. Background Art

[0002] In industrial production, some equipment that requires rotation or reciprocating motion is often used. If the fluid flowing through these equipment is directly connected through traditional pipelines, the pipelines will be entangled during the rotation or reciprocating motion, seriously affecting the operation of the equipment. Therefore, current rotating or reciprocating equipment usually uses a rotary distributor to convey the fluid between the rotating body and the fixed body of the equipment.

[0003] For example, Chinese patent CN218719579U discloses a multi-channel rotary joint, which reduces the friction between the cylinder and the rotating body by setting the diameter of the connection between the cylinder and the rotating body to be consistent. At the same time, the non-uniformly arranged second through holes and the uniformly arranged first through holes are connected to each other, thereby improving space utilization and making the structure more streamlined.

[0004] However, the multi-channel rotary distributor needs to maintain sealing with the outside and between each channel. If the seal fails at a certain place, it will affect the use of the equipment, and it is difficult for this device to detect the sealing between the various channels of the distributor; and when the oil flow rate entering the distributor suddenly increases, it will cause impact on the connection points between the back-end equipment and the distributor and the back-end equipment, affecting the stability of the equipment connection.

[0005] Based on this, the utility model designs a rotary distributor with adjustable flow rate to solve the above problems. Utility Model Content

[0031] Example 1

[0032] Please refer to the instruction manual Figure 1-3 , a rotary distributor with adjustable flow rate, comprising a cylinder 1 and a rotating body 2;

[0033] The cylinder 1 and the rotating body 2 are rotatably connected via a bearing; multiple groups of oil supply channels are arranged on the cylinder 1 and the rotating body 2, and each group of oil supply channels includes a first oil channel opening 11, a first annular groove 12, a second oil channel opening 21, a radial groove 22, and a second annular groove 23 that are connected; the outer side of the cylinder 1 is provided with a first oil channel opening 11, and the inner wall of the cylinder 1 is provided with a first annular groove 12; the rotating body 2 is provided with a second oil channel opening 21 and a radial groove 22, and the outer wall of the rotating body 2 is provided with a second annular groove 23; the first annular groove 12 and the second annular groove 23 constitute an annular oil channel; multiple groups of sealing mechanisms 3 are installed on the cylinder 1 and the rotating body 2, and the multiple groups of sealing mechanisms 3 are distributed on both sides of the second annular groove 23 and between multiple second annular grooves 23;

[0034] The sealing mechanism 3 includes a sealing component 31 and a leak point positioning component 32 . The sealing component 31 is installed between the cylinder 1 and the rotating body 2 , and the leak point positioning component 32 is installed on the rotating body 2 .

[0035] In this embodiment, when the flow-adjustable rotary distributor is working normally, the first annular groove 12 and the second annular groove 23 form a closed annular oil passage. After the oil enters the oil passage between the first annular groove 12 and the second annular groove 23 from the first oil passage opening 11, it enters the radial groove 22 through the second oil passage opening 21 in the second annular groove 23 and flows out through the radial groove 22. The sealing assembly 31 keeps each group of the first annular groove 12 and the second annular groove 23 in a sealed state, so that when the rotary body 2 rotates, the multiple channels of the oil always keep their own flow state. The oil flow in the oil passage is suddenly When it increases, the oil flow rate is reduced by adjusting the component 4, so that the oil flow rate entering the radial groove 22 will not increase sharply, thereby making the oil flowing out of the radial groove 22 more stable; at the same time, the oil channels between the multiple groups of first annular grooves 12 and the second annular grooves 23 are kept sealed by the sealing component 31; if the seal between the oil channel and the outside or the seal between the multiple groups of oil channels fails, the failed sealing position can be quickly located by the leakage point positioning component 32, so that the sealing position can be repaired in time, avoiding the situation where the sealing failure between the multiple groups of oil channels is not discovered in time, thereby improving the stability of the device.

[0036] Example 2

[0037] like Figure 1-5 As shown, as a preferred embodiment of the present utility model, the sealing assembly 31 includes a sealing groove 311 and a sealing ring 312 , and a plurality of sealing grooves 311 for accommodating the sealing ring 312 are provided on the rotating body 2 .

[0038] The leak point locating assembly 32 includes a detection assembly and an observation assembly. The detection assembly is installed inside the rotating body 2, and the observation assembly is installed at the outer end of the rotating body 2.

[0039] The detection component includes a fine hole 321 and a through hole 322 . The sealing groove 311 is provided with a through hole 322 . The rotating body 2 is provided with a fine hole 321 communicating with the through hole 322 .

[0040] The observation assembly includes a notch 323 and an observation plate 324 . The outer end of the rotating body 2 is provided with a notch 323 communicating with the pore 321 , and the observation plate 324 is fixedly mounted on the notch 323 .

[0041] The adjustment assembly 4 includes an elastic block 41 , an accommodating cavity 42 and a through groove 43 . The first annular groove 12 is provided with a through groove 43 and two accommodating cavities 42 . The two accommodating cavities 42 are connected through the through groove 43 . The elastic block 41 is fixedly mounted on the accommodating cavity 42 .

[0042] The through groove 43 and the accommodating cavity 42 are filled with hydraulic oil.

[0043] A filler that is easy to absorb oil is installed in the groove 323.

[0044] In this embodiment, when the sealing component 31, the leakage point positioning component 32 and the adjustment component 4 work normally, the oil passage between the first annular groove 12 and the second annular groove 23 is isolated from the outside through the sealing groove 311 and the sealing ring 312, and the oil passages between the multiple groups of first annular grooves 12 and the second annular grooves 23 are kept in a sealed state independently of each other; when the sealing condition is good, the oil is blocked by the sealing ring 312 and does not enter the inside of the sealing groove 311; when the sealing fails, the oil enters the inside of the sealing groove 311 and flows into the slot 323 through the through hole 322 and the pore 321, and the oil is absorbed by the filler in the slot 323, and the color change of the filler is observed through the observation plate 324; if the color of the filler in the observation plate 324 changes, it indicates that the slot 323, the through hole 322 and the pore 321 corresponding to the observation plate 324 have entered the oil, and the sealing state of the sealing groove 311 corresponding to the pore 321 fails; thereby realizing the detection of the sealing state and rapid positioning;

[0045] When the oil flow rate in the oil channel between the first annular groove 12 and the second annular groove 23 suddenly increases, the oil pressures at the two elastic blocks 41 in the same oil channel are different at this time, and the elastic block 41 at the location with larger oil pressure is pushed to deform into the accommodating chamber 42, thereby pushing the hydraulic oil in the through groove 43 to push the elastic block 41 at the location with smaller oil pressure to deform outward of the accommodating chamber 42, so that concave and convex parts are generated in the oil channel to block the oil, thereby reducing the oil flow rate, thereby reducing the growth rate of the oil flow rate flowing into the radial groove 22; after the oil flow rate stabilizes, the hydraulic values ​​at the two elastic blocks 41 in the same oil channel are consistent, and the two elastic blocks 41 are reset to keep the oil channel unobstructed, thereby avoiding the impact of the surge in flow rate on the device and improving the stability of the output oil.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
