Abstract
The utility model relates to a heat compensator of heat pipe, in particular to a stuffing rotary muffle compensator, wherein an outer sleeve sheathes an inner sleeve, the tail of the inner sleeve is provided with an annular boss, two ends of the outer sleeve are respectively provided with a fixed retainer ring and a movable retainer ring, the end face of the boss and the end face of the movable retainer ring are provided with a flat roller bearing therebetween, two ball bearings are provided between the fixed retainer ring and the inner sleeve and between the movable retainer ring and the inner sleeve, a seal chamber between the fixed retainer ring and the movable retainer ring is mounted with a seal element. The utility model has simple structure, reliable operation and long service life, which adds a flat roller bearing for rotational location and bearing blind flange stress to form the inner and outer sleeves into a compensator capable of rotating relatively and eliminate the blind flange stress on a fixing frame. Compared with push-free balance type compensator, the heat compensator has simple production, low cost and wide application.
Description
Technical field:
The utility model relates to the heat distribution pipeline heat compensating unit.
Background technique:
Heat distribution pipeline is because high temperature media such as delivering hot water, steam, so the piping displacement that the medium temperature variation causes need adopt various compensation methodes to compensate, and there is big blind plate power in sleeve expansion joint commonly used, filling type compensator such as China Patent No. 200420063363.1 announcements, though have reliable operation, advantages such as the life-span is long, but still have the shortcoming of the big blind plate power of sleeve expansion joint commonly used, increase support bracket fastened design difficulty and pipe network and laid cost.The filling type balance type compensator that adopts China Patent No. 20042007655.8 to announce, though overcome the shortcoming that sleeve expansion joint commonly used has blind plate power, its complex structure, a no thrust-balancing type compensator is equivalent to three filling type compensators.No thrust-balancing type compensator is because manufacture difficulty is big, and the cost of production height has limited it and further applied.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, provides a kind of notes to fill out the turnbarrel compensator, simple in structure, reliable operation, and the life-span is long, has eliminated the blind plate power that acts on the fixed support up hill and dale, and cost is low.
The scheme that the utility model is adopted for achieving the above object is: annotate and fill out the turnbarrel compensator, be set with interior cover in the overcoat, interior cover tail end is provided with an annular boss, the overcoat two ends are equipped with fixedly baffle ring and movable baffle ring respectively, between raised head face and the movable baffle ring end face plane roller bearing is housed, fixedly between baffle ring, movable baffle ring and the interior cover ball bearing is housed respectively, fixedly in the Seal cage Sealing is housed between baffle ring and the movable baffle ring.
The outer surface of cover, interior cover tail end boss are surface hardening and anti-corrosion treatment end face with the surface of contact of movable baffle ring in described.
Described fixedly baffle ring and movable baffle ring are high-strength ductile cast iron baffle ring anticorrosion and that anti-attrition is handled.
Described Sealing is close encapsulation and soft seal combination.
Described close encapsulation is the compression molding stuffing box packing; Soft seal is the compressible seal filler, is made up of Expanded graphite powder and high-temperature lubricant etc.
Described fixedly baffle ring is fixedlyed connected, is threaded or weld by pin with overcoat.
The tail end of described overcoat is provided with limited ring and fixedlys connected with overcoat.
The utility model is filled out on the sleeve expansion joint architecture basics in original annotation, the two ends that proposed a kind of interior cover adopt the ball bearing that has isolator to carry out radial location, axially adopt the plane roller bearing carrying, realize that by pressure medium the notes of reliable sealing are filled out the turnbarrel compensator.The relative rotary motion of cover and outer inner room compensates no blind plate power and medium reaction thrust on the fixed support to the extending amount of pipeline in utilizing.Because the radial and axial rolling bearing that all adopts, the running torque of compensator is little, rotates flexibly.Simultaneously, owing to adopt the filling type structure of using the advanced person of test at home and abroad through many decades, sealing is reliable, long service life.In addition, load for close encapsulation and soft seal by pressure medium during the utility model work, filler realizes that owing to burning the loss that mistake or wearing and tearing cause compensator is from safeguarding in the compensation work automatically.
The utility model has been inherited simple in structure, the reliable operation of sleeve expansion joint, the advantage that life-span is long, the plane roller bearing that has increased rotation positioning and born blind plate power makes in it overcoat become can realize compensation device in relative rotation, eliminated the blind plate power that acts on the fixed support up hill and dale, it is compared with no thrust-balancing type compensator simultaneously, and it is simple in structure, and is easy to manufacture, cost is low, so it has broad application prospects.

Fig. 3 connects the connecting structure schematic representation for overcoat and fixed stop boxing.
Embodiment:
Notes are as shown in Figure 1 filled out the turnbarrel compensator, it by interior cover 1, overcoat 4, fixedly baffle ring 2, pin 3, material feeding port 5, plug screw 6, can annotate stuffing box packing 7, close encapsulation 8, movable baffle ring 9, ball bearing 10, plane roller bearing 11 and limited ring 12 and form.Cover 1 in being set with in the overcoat 4, the overcoat tail end is welded with limited ring 12, the axial position of cover 1 in being used to limit.Interior cover tail end is provided with an annular boss 13, its left side and be contained in the overcoat between the right side of movable baffle ring 9 plane roller bearing 11 is installed, for the bearing capacity that improves contact surface with prevent surface etching, the outer surface of interior cover 1 and the left side of interior cover tail end boss and the right side of movable baffle ring 9 are the end face that carries out surface hardening and anti-corrosion treatment, the overcoat the other end is installed with fixedly baffle ring 2 by pin 3, the size of pin and quantity are determined by the load that it bore, fixedly in the circular groove of baffle ring 2 and movable baffle ring 9 ball bearing is housed respectively, two ball bearings 10 are realized inside and outside inner room radial location.In the Seal cage of forming by interior cover 1, left baffle ring 2, overcoat 4 and right baffle ring 9 Sealing is housed, Sealing is a soft seal 8 to be housed in the middle of two close encapsulation 7 form, soft seal can be annotated stuffing box packing and be injected by the high injection material instrument of material feeding port 5 usefulness that is contained on the overcoat 4, tightens plug screw 6 after material feeding is finished.
The utility model overcoat and fixedly baffle ring 2 also can adopt scyewed joint, as shown in Figure 2, perhaps adopt or welding connects as shown in Figure 3.Movable baffle ring 9 can be moved to the left under the pressure medium effect when work, compresses close encapsulation 8 and soft seal 7, and the burning that the compensates filler automatically wearing and tearing of becoming estranged realize the maintenance certainly when compensator is worked.
