Background technique
Stuffing box packing is called again compression filler (Gland Packings) sealing, is commonly called as packing (Packings).Packing_seal is the most ancient a kind of sealing configuration, in the water lifting machinery of Ancient Times in China, blocks leakage by the method for filling cotton yarn, and the steamer occurring the earliest is in the world also to adopt this seal form.And 19th century oil and natural gas exploitation technology production and development, make gland sealed material have new development.To 20th century, packing seal is relatively simple for structure because of it, and the charge is small, wide material sources and obtain the favor of many industrial departments.
Packing seal is mainly used in the motive sealings such as the process machine and equipment motion parts in machinery industry, such as plunger or the piston rod of the rotating shaft sealing of centrifugal pump, compressor, vacuum pump, stirrer, reactor and reciprocating pump, reciprocal compressor, and sealing between valve rod and the fixing body of the motion valve of spinning.
Existing stuffing box packing is generally formed by more soft thread braiding, and sectional area is that square or rectangular, circular bar are filled in seal chamber conventionally, thereby realizes sealing.But the stuffing box packing in this conventional cross section is not well positioned to meet the sealing needs at the shutoff position of some cross section abnormal shapes, in use, wear and tear larger, very easily appearance wearing and tearing come off and cause the situation that loses former sealing effect to occur.
Summary of the invention
The technical problem to be solved in the present invention is that the stuffing box packing that how the to solve profiled-cross-section shutoff position regular sections situation about coming off of in use wearing and tearing occurs, and for prior art deficiency, proposes a kind of stuffing box packing that can use for a long time that is applicable to irregular cross section.
The present invention is that the technological scheme that solves the problems of the technologies described above proposition is: a kind of special-shaped stuffing box packing, comprise the packing body of square-section, it is the 3rd trapezoidal flexible element that a side of described packing body is provided with the first flexible element that two cross sections are parallelogram and the second flexible element and a cross section; Described the 3rd flexible element is between described the first and second flexible elements, and described the 3rd flexible element cross section is identical with the center line in described packing cross section, and the cross section of described the first flexible element and the second flexible element is about described center line symmetry.
The improvement of technique scheme is: described the first flexible element, the second flexible element and the 3rd flexible element do not contact mutually the in the situation that of non-extruding.
The improvement of technique scheme is: described the first flexible element and the second flexible element stretch both sides to the left and right with respect to described center line.
The improvement of technique scheme is: described the first flexible element, the second flexible element and the 3rd flexible element are separable structure.
The present invention adopts the beneficial effect of technique scheme to be: this case by making improvement on regular sections packing, a kind of special-shaped stuffing box packing is provided, thereby meet irregular cross section shutoff demand not, by mutually pushing and coordinate the wearing and tearing that reduce the packing body of irregular cross section to sealing use between the first flexible element, the second flexible element and the 3rd flexible element, increase the service life.And because flexible element is separablely therefore can combine according to actual needs, use one or more difform flexible elements to meet the sealing demand in all kinds of irregular cross sections, avoid being subject to single shape restriction and the situation that can not seal that causes occurs.
