Description

The universal compensator of a kind of pipeline

The utility model relates to a kind of compensation of pipeline link, the universal compensator of especially a kind of pipeline.

In fields such as electric power, mine, metallurgy, building materials.The use of powder transfer line is very general.Owing to often misplace between installation and the temperature factor pipeline, the augular offset phenomenon and the length of pipeline that is caused of expanding with heat and contract with cold change, and the erosion of existence generation, wear problem, more than these problems bring very the large economy loss to the user, in order to prevent the generation of these situations, at present generally use pipeline compensator that the problems such as dislocation of pipeline are compensated, but using more at present is with stainless steel or castiron pipeline compensator, this pipeline compensator cost height, maintenance, change difficulty, serious wear, working life is short, and its using effect is very undesirable.

It is low that the purpose of this utility model provides a kind of cost, and compensation effect is good, and maintenance is convenient, wear resistance is good, the universal compensator of the pipeline of long service life.

The technical solution of the utility model is: the universal compensator of a kind of pipeline, form by two identical ball-type joint and telescopic tube devices between two spherical type heads of structure, the ball-type joint is by the interior bulb of an end dribbling type outer arced surface, the outer bulb of one end dribbling type intrados and the flange of dribbling type intrados constitute, one end of the type of bulb dribbling outside intrados is fixedly connected with flange, in the flange of flange and dribbling type intrados is incited somebody to action by bolt, outer bulb and combining as a whole, have annular groove on the intrados of bulb outside, in annular groove, be equipped with sealing material, interior, outer bulb and internal face on be compounded with metal or nonmetal wearing layer, above-mentioned telescopic tube device connects platen by telescopic tube and annular and constitutes, wherein the do not dribble outer wall welding of type outer arced surface one end of the inwall of telescopic tube one end and interior bulb connects, the do not dribble end outer wall socket of type intrados of the inwall of the other end and outer bulb, be welded with annular tie-plate on its outer wall, bulb is not dribbled and is welded with annular fixed disk on the end outer wall of type intrados outside, annular connects platen between annular fixed disk and annular tie-plate, and annular fixed disk and annular tie-plate are combined as a whole by bolt, between annular tie-plate and annular connection platen, closed chamber is arranged, sealing material is arranged in closed chamber, on the internal face of telescopic tube, be compounded with metal or nonmetal wearing layer.Above-mentioned abrasion-resistant metal layer is low complexing gold cast iron layer or 2 wear-resistant white cast layer.Described nonmetal wearing layer is ceramic layer or rubber layer.

The universal compensator of the utility model pipeline can solve the pipeline parallel misalignment, the length change that augular offset, pipeline are expanded with heat and contract with cold and formed is in order to improve the working life of compensator, compound one deck ceramic wearing coat on the wall within it, significantly improved its working life, and the universal compensator of this pipeline is modular construction, and is in light weight, install simple, easy to maintenance, compensation effect is good, can satisfy different installations, usage requirement.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the utility model structural representation.

Structure of the present utility model as shown in Figure 1, form by two identical ball-type joint and telescopic tube devices between two ball-type joints of structure, the ball-type joint is made of the interior bulb 1 of an end dribbling type outer arced surface, the outer bulb 4 of an end dribbling type intrados and the flange 2 of dribbling type intrados, bulb 4 dribbling type intrados one end is fixedly connected with flange 11 outside, and the flange 2 of flange 11 and dribbling type intrados combines as a whole inside and outside bulb 1 and 4 by bolt 12.Bulb 1 in same ', ectosphere 4 ' and another ball-type joint of flange 2 ' composition of dribbling type intrados, interior bulb 1 and 1 ' freely any direction rotate, and the mutual action by two ball-type joints cooperates to finish and regulates pipeline dislocation and augular offset, the telescopic tube device connects platen 7 by telescopic tube 6 and annular and constitutes, wherein the do not dribble outer wall welding of an end of type outer arced surface of the inwall of telescopic pipe 6 one ends and interior bulb 1 connects, the do not dribble end outer wall socket of type intrados of the inwall of the other end and outer bulb 4, and can produce free-running operation, change to solve the length of pipeline that forms owing to expanding with heat and contract with cold, be welded with annular fixed disk 9 on the outer wall of bulb 4 outside, on the outer wall of telescopic cover, be welded with annular tie-plate 8, annular connects platen 7 between annular fixed disk 9 and annular tie-plate 8, and combine as a whole by bolt 14, between annular tie-plate 8 and annular connection platen 7, closed chamber 15 is arranged, sealing material 16 is arranged in closed chamber 15, have annular groove on the intrados of bulb 4 outside, be equipped with sealing material 13 in annular groove 3, sealing material 16 and 13 is measures of taking for the sealability that solves pipeline.On the internal face of telescopic tube 6, be compounded with abrasion-resistant metal layer 10 (as low complexing gold cast iron layer or 2 wear-resistant white cast layer) or nonmetal wearing layer 10 (as ceramic layer or rubber layer).Interior bulb 1 and 1 ', outer bulb 4 and 4 ' and the inwall of telescopic tube 6 on be compounded with wear-resisting abrasion-resistant metal layer 10 (as low complexing gold cast iron layer or 2 wear-resistant white cast layer) or nonmetal wearing layer 10 (as ceramic layer or rubber layer) respectively, to solve the wear problem at pipe joint position.
