Description

Rotary joint with peripheral wall channel structure

Technical Field

The utility model belongs to the technical field of crane pipe rotary joints, and particularly relates to a rotary joint with a peripheral wall channel structure.

Background

In fluid transportation, the oil filling riser is used for carrying loading and unloading fluid, and fluid medium includes crude oil and pitch etc. and this kind of fluid medium solidifies easily and then blocks up the oil filling riser easily under the low temperature condition, increases heating structure on the pipeline of present oil filling riser, and then improves the pipeline temperature through the heating for this kind of fluid medium flows smoothly, but can't obtain the heating to rotary joint, makes partial fluid medium appear the solidification condition in rotary joint department, need clear up, is unfavorable for the loading and unloading progress like this.

Disclosure of Invention

The utility model aims to design a rotary joint with a peripheral wall channel structure, which can lead hot water or hot steam into the peripheral wall channel to realize heat transfer on the inner wall of the rotary joint so as to heat a viscous fluid medium.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:

a rotary joint of a peripheral wall channel structure is characterized in that: the rotary joint comprises a flange, an inner ring and an outer ring, the flange is connected with the outer ring through screws, the inner ring is arranged in the outer ring, the inner ring and the flange are both composed of an inner tube and an outer tube, a channel is formed between the inner tube and the outer tube, a plug extends out from the channel of the inner ring, the plug can be inserted into a channel opening of the flange to realize communication between the channels, and a sealing ring is arranged between the plug and the channel opening.

Furthermore, the flange and the rear end of the inner ring are connected with a crane pipe, and the crane pipe is composed of an inner pipe and an outer pipe.

Further, steel ball grooves are formed in the pipe walls of the inner ring and the outer ring, steel balls are arranged in the steel ball grooves, and dust rings are arranged in the dust ring grooves of the inner ring.

Furthermore, the contact surfaces of the inner ring, the flange and the outer ring are provided with sealing rings.

Furthermore, a sealing ring is arranged on the contact surface of the lower surface of the inner wall of the flange and the inner wall of the inner ring.

Furthermore, the outer ring is also provided with a plug.

Furthermore, the number of the dust ring and the number of the steel balls are two respectively.

The technical scheme can obtain the following beneficial effects:

the rotary joint has a simple structure, the inner ring and the flange of the rotary joint are designed into an inner pipe and an outer pipe structure, a heat medium channel is formed in the middle, hot water or hot steam can be introduced to heat the whole pipeline of the oil filling riser, and fluid media such as viscous crude oil and the like can be smoothly loaded and unloaded.

Secondly, the channel that the inner circle formed extends outward and forms the plug shape, can better with flange entrance grafting, in order to prevent that the hot medium from revealing, is equipped with the sealing washer between plug and entrance.

The whole structure can be completely butted with the existing inner and outer pipe crane pipe pipelines for use, and the requirement of low-temperature operation is met.

Drawings

Fig. 1 is a schematic view of a rotary joint.

In the figure:

in the figure: 1. an inner ring; 2. a flange; 3. a loading arm pipeline; 4. steel balls; 5. a channel; 6. a seal ring; 7. a dustproof ring 8, a plug 9, an outer ring 10, a plug 11, a screw 12, an inner pipe 13 and an outer pipe.

Detailed Description

The utility model is further described below with reference to the accompanying drawings:

as shown in fig. 1, the rotary joint of the peripheral wall channel structure comprises a flange 2, an inner ring 1 and an outer ring 9, wherein the flange is connected with the outer ring through a screw 11, the inner ring is arranged in the outer ring, the inner ring and the flange are both composed of an inner pipe and an outer pipe, a channel 5 is formed between the inner pipe 12 and the outer pipe 13, a plug 10 extends outwards from the channel of the inner ring, the plug can be inserted into a channel opening of the flange to realize communication between the channels, and a sealing ring is arranged between the plug and the channel opening. The flange and the rear end of the inner ring are connected with a crane pipe pipeline 3, and the crane pipe pipeline is composed of an inner pipe and an outer pipe. And steel ball grooves are formed in the pipe walls of the inner ring and the outer ring, steel balls 4 are arranged in the steel ball grooves, and a dustproof ring 7 is arranged in the dustproof ring groove of the inner ring. And the contact surfaces of the inner ring, the flange and the outer ring are provided with sealing rings 6. And a sealing ring is arranged on the contact surface of the lower surface of the inner wall of the flange and the inner wall of the inner ring. And the outer ring is also provided with a plug 8. The number of the dust ring and the number of the steel balls are two respectively.

Example (b):

according to the rotary joint shown in figure 1, an inner ring and a flange are of a rotary joint formed by an inner pipe and an outer pipe, an outer ring is sleeved outside the inner ring, a plug is further arranged outside the outer ring, two steel balls 4 and a dust ring 7 are arranged between the inner ring and the outer ring, the inner ring and the flange are connected through bolts, sealing rings are arranged among contact surfaces of the inner ring, the outer ring and the flange, and the sealing rings are arranged between the inner ring and the flange.
