Abstract
The utility model relates to a rotary pipe joint device. The ports of a fixed pipe and a rotary pipe are respectively provided with mating flanges, and the connection end surfaces of the mating flanges are provided with grooves for containing sealing rings and the sealing rings arranged in the grooves. The rotary pipe joint device has the advantages of easy processing and on-site assembly and good sealing effect.
Description
Technical field:
The utility model relates to a kind of swivel joint device, is specially adapted to the dynamic seal (packing) of swivelling pipe and fixed tube in the air purification field.
Background technique:
For satisfying the rotary sack cleaner of action of low-voltage pulse of the special development of big air quantity gas cleaning needs, be a kind of efficient, economic, reliable, Processing capacity dusting apparatus big, easy to use, be applicable to the big air quantity gas cleaning of industries such as metallurgy, machinery, chemical industry, building materials.Wherein, spraying and blowing organ is one of core component of the rotary sack cleaner of action of low-voltage pulse, and it is made, crucial effects is played in the good safe and effective operation to sack cleaner of installation quality.Introduce the Shandong special skill or feat art initial stage, be subjected to domestic existing manufacturing level and the big restriction of assembled on site difficulty, after installing, blowing device is difficult to satisfy the quality of fit requirement of each part, particularly the quality of fit between fixed tube and the swivelling pipe causes faults such as the frequent appearance of blowing device operation is stuck, wearing and tearing.
The prior art scheme is to annotate the ester sealing between fixed tube and swivelling pipe, so not only needs regularly to annotate ester and leaks gas to prevent this place, and inconvenient operation; If the grease that injects too much will enter air-purifying chamber, pollute filter bag.In a word, the problem one of existence is that the grease sealing effect is poor, the 2nd, and high especially to the requirement on machining accuracy of pipe fitting fitting surface.
Summary of the invention:
The purpose of this utility model provides a kind of swivel joint device, and this swivel joint device not only is convenient to processing and assembled on site, and good sealing effect.
A kind of swivel joint device, comprise that the fixed tube that links to each other with gear-box and lower end mouth lead to the swivelling pipe of winding-up arm, described fixed tube and swivelling pipe port are respectively equipped with abutted flange, and described abutted flange connection end face is provided with and is used to hold the groove of seal ring and is arranged at the interior seal ring of groove.
Swivelling pipe and fixed tube adopt flange to be connected in the utility model, and the employing polyfluortetraethylene plate seals between the last lower flange, and will go up lower flange and connect with bolt.
Compared with prior art, the utlity model has following advantage:
1, adopts polyfluortetraethylene plate sealing, wear resistance good, can stop gas leakage.
2, because teflon is soft seal, can reduce accuracy of manufacturing and installation precision requirement to equipment.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
A kind of swivel joint device, comprise that the fixed tube 1 that links to each other with gear-box and lower end mouth lead to the swivelling pipe 2 of winding-up arm, described fixed tube and swivelling pipe port are respectively equipped with abutted flange 3, described abutted flange connects end face and is provided with the groove that is used to hold seal ring, and described seal ring is the ring seal material 4 that is arranged in the groove.Described ring seal material adopts teflon to make, and its sealing, wear resistance are good, can stop gas leakage.
Claims (2)
1. swivel joint device, comprise that the fixed tube that links to each other with gear-box and lower end mouth lead to the swivelling pipe of winding-up arm, it is characterized in that: described fixed tube and swivelling pipe port are respectively equipped with abutted flange, and described abutted flange connection end face is provided with and is used to hold the groove of seal ring and is arranged at the interior seal ring of groove.
2. swivel joint device according to claim 1 is characterized in that: described seal ring adopts teflon to make.
