Abstract
The utility model relates to a long telescopic type soot blower valve sealing structure which comprises a valve body (2), a guiding rod (7) and a guiding sleeve (1). The valve body (2) is arranged at the outer side of the middle of the guiding sleeve (1), fillings (3) are arranged between the guiding rod (7) and the guiding sleeve (1), a filling gland (4) is arranged at the upper end of the fillings (3), a gland (5) in a step shape is arranged at the outer side of the upper end of the guiding sleeve (1), the inner flange of the gland (5) abuts against the filling gland (4), the gland (5) is sleeved with a spring (6), and the lower end of the spring (6) abuts against the outer flange of the gland (5). According to the long telescopic type soot blower valve sealing structure, the gland drives the filling gland to compress the fillings under the action of the spring, so that the fillings have the good compaction degree, the valve body is sealed without leakage, and the using effect of the soot blower and stable conduction of production are ensured.
Description
Technical field
The utility model relates to a kind of long retractable soot blower valve body sealing structure, belongs to petrochemical equipment technical field.
Background technique
Long retractable soot blower is for purging superheater and the intrafascicular dust stratification of reheater tube.While blowing ash, blowing pipe and shower nozzle simultaneously rotate, and one side stretches into flue.Shower nozzle Laval nozzle formula, the jet velocity of steam or air surpasses the velocity of sound, effectively blows approximately 1.5～2 meters of grey radiuses.
Current long retractable soot blower, because the sealability of its valve body is bad, so can affect the using effect of soot blower, thereby delay production.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of long retractable soot blower valve body sealing structure of good seal performance is provided.
The purpose of this utility model is achieved in that
A kind of long retractable soot blower valve body sealing structure, be characterized in: described sealing configuration comprises valve body, guide rod and guide pin bushing, described valve body is arranged on the outside, middle part of guide pin bushing, between described guide rod and guide pin bushing, be provided with filler, the upper end of filler is provided with Gland, and the upper end arranged outside of described guide pin bushing has the gland that is step-like, and inward flange and the Gland of gland offset, on gland, be arranged with spring, the lower end of spring and the outward flange of gland offset.
A kind of long retractable soot blower valve body sealing structure of the utility model, its filler is carbon fiber or Expanded graphite circle.
Compared with prior art, the beneficial effects of the utility model are:
A kind of long retractable soot blower valve body sealing structure of the utility model, under the effect of spring, gland drives Gland to compress filler, makes filler have good compaction degree, guaranteed that the sealing of valve body is without leakage, guaranteed that the using effect of soot blower and the stable of production carry out.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of long retractable soot blower valve body sealing structure of the utility model.
In figure:
Valve body 2,
Filler 3,
Gland 4,
Gland 5,
Guide rod 7.
Embodiment
Referring to Fig. 1, the utility model relates to a kind of long retractable soot blower valve body sealing structure, it comprises valve body 2, guide rod 7 and guide pin bushing 1, described valve body 2 is arranged on the outside, middle part of guide pin bushing 1, between described guide rod 7 and guide pin bushing 1, is provided with filler 3, and the upper end of filler 3 is provided with Gland 4, the upper end arranged outside of described guide pin bushing 1 has the gland 5 that is step-like, the inward flange of gland 5 and Gland 4 offset, and are arranged with spring 6 on gland 5, and the outward flange of the lower end of spring 6 and gland 5 offsets.
Working principle: under the effect of spring 6, gland 5 drives Gland 4 to compress filler 3, makes filler 3 have good compaction degree, has guaranteed that the sealing of valve body 2 is without leakage.
