Abstract
The utility model relates to a novel stuffing box easy to disassemble and assemble. The novel stuffing box easy to disassemble and assemble comprises a casing, a stuffing box body, sealing stuffing TCF, sealing stuffing NFS, a water seal ring, a restrictor ring and a sealing gland, the stuffing box body and the restrictor ring are fixed; the stuffing box body and the casing are fixed; the sealing stuffing TCF, the water seal ring, the sealing stuffing NFS are sequentially arranged in the gap between the stuffing box body and a shaft sleeve, and the sealing stuffing TCF is in contact with the restrictor ring; the sealing gland and the stuffing box are fixed and in sealing contact with the sealing stuffing NFS. The novel stuffing box easy to disassemble and assemble has the advantages of being convenient to disassemble and maintain, high in disassemble precision, reliable, stable, and suitable for slag-water working conditions and the like. The problem that an original stuffing box structure is difficult to disassemble and maintain is solved, and the labor intensity is greatly reduced.
Description
Technical field
The utility model relates to a kind of easy-to-dismount new packing case, particularly relate to a kind of overcome press that to contain granular filler case stuffing box space long and narrow in existing, the restrictor ring that is contained in the Stuffing box bottom is difficult to take out the easy-to-dismount new packing case of the deficiency of maintain and replace.
Background technique
In press and to contain the typical Stuffing box structure of particle and be: at Stuffing box bottom installing restrictor ring, and introduce pressure than the clean liquid of the high about 0.05MPa of pressure medium as washing solution, the particle in the prevention sealed medium enters the filler rubbing surface.At Stuffing box middle part installing seal cage, introduce clean liquid and be lubricated, reduce the wearing and tearing of filler, improve working life, can improve the nonuniformity that filling pressure distributes vertically simultaneously.Shortcoming is because the stuffing box space is long and narrow, and the restrictor ring that is contained in the Stuffing box bottom is difficult to take out maintain and replace, causes restrictor ring can not change for a long time, and throttle orifice stops up, and high pressure washing liquid can not be introduced, and makes particle very easily enter the filler rubbing surface.
Press the requirement that contains the repair and replacement of granular filler case along with pressing the continuous expansion that contains granular filler box structure output, existing Stuffing box structure can not satisfy long-term high pressure pulp water operating mode centering in such, be badly in need of a kind of new Stuffing box structure easy to assemble of design.
Summary of the invention
The technical problems to be solved in the utility model provides the easy-to-dismount new packing case of pressing the problem that contains granular filler case maintenance difficult in a kind of solution for a long time.
For solving the problems of the technologies described above, a kind of easy-to-dismount new packing case of the utility model comprises: housing, filler casing, stuffing box packing TCF, stuffing box packing NFS, seal cage, restrictor ring and sealing gland; Filler casing and restrictor ring are fixed; Filler casing and housing are fixed; In the gap between filler casing and axle sleeve, stuffing box packing TCF contacts with restrictor ring successively for stuffing box packing TCF, seal cage, stuffing box packing NFS; Sealing gland and filler casing are fixed, and contact with stuffing box packing NFS sealing.
The filler casing is provided with the high pressure washing water lines, and the high pressure washing water lines is divided into upper pipeline and lower pipeline; Upper pipeline washes packing seal through seal cage; Lower pipeline forms the annular water seal to sleeve outer surface through restrictor ring.
Lower pipeline is provided with one-way valve.
Sealing gland is fixed by bolt and nut and filler casing.
Be provided with the twice round section joint ring between filler casing and the housing.
The flange of filler casing is provided with auxiliary top wire hole.
The utlity model has characteristics such as dismounting is easy to maintenance, decomposition refills the precision height, reliable and stable, suitable pulp water operating mode.Solve the problem of former Stuffing box structure dismounting maintenance difficult, greatly alleviated labor intensity.
Description of drawings
Fig. 1 is the schematic representation of easy-to-dismount new packing case provided by the utility model.
Among the figure: 1 is that filler casing, 2 is that high pressure washing water lines, 3 is that sealing gland, 4 is that stuffing box packing NFS, 5 is that nut, 6 is that axle sleeve, 7 is that round section joint ring, 8 is that bolt, 9 is that restrictor ring fixing bolt, 10 is that restrictor ring, 11 is that stuffing box packing TCF, 12 is that seal cage, 13 is that housing, 14 is the M5 tapped hole.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
The utility model comprises: housing 13, filler casing 1, stuffing box packing TCF11, stuffing box packing NFS4, seal cage 12, restrictor ring 10 and sealing gland 3.
Filler casing 1 is fixing by bolt 8 with housing 13, and filler casing 1 and housing 13 radially are provided with twice round section joint ring 7 between the contact surface.
Stuffing box packing TCF11, seal cage 12, stuffing box packing NFS4 in the gap between filler casing 1 and axle sleeve 6, are set to sealing gland 3 on the axle sleeve 6 successively, are pressed into stuffing box packing in the Stuffing box singly; Sealing gland 3 is fixed by bolt and nut 5 and filler casing, and contacts with stuffing box packing NFS4 sealing; Stuffing box packing TCF11 contacts with restrictor ring 10.
Attention: the dismounting seal cage is used when changing stuffing box packing after four M5 tapped holes 14 of seal cage 12 are convenient to, so will guarantee that the aperture of its tapped hole is outside when laying seal cage 12.
Filler casing 1 is provided with the high pressure washing water lines, and the high pressure washing water lines is divided into upper pipeline and lower pipeline; Upper pipeline plays lubricated effect through seal cage 12 flushing packing seals.Lower pipeline washes in container through restrictor ring 10, stops aqueous particulate to enter Stuffing box, plays the effect of flushing.Lower pipeline arranges one-way valve and stops aqueous particulate refluence water inlet seal ring 12 flushing lines.
When stuffing box packing is revealed serious, when needing to change filler, seal cage 12 and restrictor ring 10, earlier the stuffing box packing of the circle of six between sealing gland 3 and the seal cage 12 is taken out, the bolt 8 of back-outing then, bolt 8 is screwed in the auxiliary top wire hole of filler casing 1 flange again, filler casing 1 is ejected, successively from filler casing 1 rear portion dismounting restrictor ring 10, two circle stuffing box packing TCF11 and seal cages 12.
