Abstract
The utility model belongs to the technical field of the seal of the reciprocating plunger of a liquor pump, providing a sealing device of the reciprocating plunger, and the sealing device of the reciprocating plunger can be arranged in a liquid cylinder body with simple structure and small volume and weight. The utility model is formed by that an inside guiding ring (3) and a sealing material filling ring (4) are assembled into a whole by a thin-walled material filling sleeve (6), and are adjusted and compressed by a threaded pressure ring (5) and a threaded back ring (7). The utility model makes full use of the intensity of the liquid cylinder body, reducing the volume which is occupied by sealing material filling members in the pump. The device has the advantages of reliable seal, very convenient replacement, adjustment, and disassembly and assembly.
Description
The utility model belongs to to-and-fro motion liquid pump plunger seal technical field.
The plunger seal structure of existing high pressure reciprocating pump is independent stuffing box form.It is by one the band high pressure flange thick walled cylinder be Stuffing box.The packing ring and the guide ring of ring is equipped with in inside.The rear end holds out against packing ring and guide ring fixing with the microgroove flange of a band circular hole.The plunger that middle perforation one cylindrical body moves reciprocatingly.Whole stuffing box is installed on pump liquid cylinder outside, and volume is big and heavy.When changing inner sealing filler and guide ring, need whole stuffing box parts to be unloaded the effort of taking a lot of work.Because stuffing box occupies the segment space of pump, the volume of pump is strengthened.The material that Stuffing box uses is more.Cost is higher in addition.
The purpose of this utility model is to design a kind of liquid cylinder inside that can be loaded on pump, and is simple in structure, the reciprocal plunger seal arrangement that volume weight is all less.
Improvements of the present utility model are: be with the thin-walled cylinder barrel at the end as the filler cover with one, filler cover bottom has a circular hole that is a bit larger tham plunger diameter, the oral area of filler cover has internal thread, in the filler cover, to filler cover oral area circular guide ring is housed successively from filler cover bottom, congratulate the annular seal packing ring, circular guide ring, screw in guide ring and the packing ring that compresses in the filler cover in the filler cover with a threaded pressure ring then, screw thread back of the body ring is equipped with at the threaded pressure ring rear portion, in order to the collet threaded pressure ring, plunger is in filler cover and guide ring and stuffing box packing ring, and the filler cover can integral body be packed in the liquid cylinder.
The utility model is simple in structure, light and handy, is easy to processing and fabricating.The filler cover adopts thin wall-type, and the intensity that can make full use of liquid cylinder is offset the pressure of highly pressurised liquid.When changing stuffing box packing, can be with the whole sealing device integral disassembly, assembly, very convenient.
Embodiment of the present utility model provides in conjunction with the accompanying drawings.
Accompanying drawing is a set type reciprocal plunger seal arrangement sectional drawing.
(1) is liquid cylinder among the figure, and (2) are O-ring seals, and (3) are guide ring, and (4) are the stuffing box packing ring, and (5) are threaded pressure ring, and (6) are the filler cover, and (7) are screw thread back of the body ring, and (8) are plunger.
In the present embodiment, filler cover (6) is done with the steel circular cylindrical thin-walled cylinder, have a circular hole that is a bit larger tham plunger diameter in its bottom, at its oral area one internal thread is arranged, in filler cover (6), to oral area circular guide ring (3) is housed successively from filler cover (6) bottom, circular stuffing box packing ring (4), circular guide ring (3), threaded pressure ring (5) screws in the filler cover (6) from filler cover (6) oral area, compress inner each ring, screw thread back of the body ring (7) is collet threaded pressure ring (5) again, when the stuffing box packing ring (4) of inside when becoming flexible because of wearing and tearing, can transfer threaded pressure ring (5) and screw thread back of the body ring (7), make it to remain on and compress sealing state.This model utility should be close to the bottom of filler cover (6) in the end of liquid cylinder (5), and is sealed in filler cover (6) outer radius by O-ring seals (2) by dress the time.
Claims (1)
- A kind of set type reciprocal plunger seal arrangement, be characterized in: be with the thin-walled cylinder barrel at the end as filler cover (6) with one, filler cover (6) bottom has a circular hole that is a bit larger tham plunger (8) diameter, the oral area of filler cover (6) has internal thread, in filler cover (6), to filler cover (6) oral area circular guide ring (3) is housed successively from filler cover (6) bottom, circular stuffing box packing ring (4), circular guide ring (3), use a threaded pressure ring (5) to screw in the filler cover (6) then, compress guide ring (3) and stuffing box packing ring (4) in the filler cover (6), screw thread back of the body ring (7) is equipped with at threaded pressure ring (5) rear portion, in order to collet threaded pressure ring (5), plunger (8) is through filler cover (6), in guide ring (3) and the stuffing box packing ring (4), filler cover (6) can integral body be packed in the liquid cylinder (1).
