The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of composite closed type sleeve compensator for steam is provided, and simple in structure, compensation ability is big, long service life, and maintenance cost is low, is widely used in steam line.
The technological scheme that the utility model is adopted for achieving the above object is: composite closed type sleeve compensator for steam, the core pipe is set with outer sleeve outward, between core pipe and the outer sleeve stuffing box packing is housed, the fixed end outer sleeve is by the fixedly connected tail pipe of guide-localization one ring, stuffing box packing between core pipe and the outer sleeve is fixed end stuffing box packing and movable end stuffing box packing, two sections stuffing box packing do not link to each other, and on the corresponding outer sleeve of fixed end stuffing box packing syrup filling tip are housed.
Described fixed end stuffing box packing is between guide-localization one ring and guide-localization two rings graphite packing to be housed, and is equipped with between the graphite packing and annotates packing packing material; The movable end stuffing box packing is between guide-localization two rings and guide-localization three rings graphite packing to be housed, and is equipped with between the graphite packing and annotates packing packing material.
Described guide-localization one ring outer wall has seam, and outer sleeve and tail pipe are divided in the seam both sides, and the three is by being welded to connect.
Described guide-localization two rings are two stiffening rings, and outer sleeve inner wall has seam, and two guide-localization two rings are divided in outer sleeve inner wall seam both sides.
Described guide-localization three rings are welded to connect with the pressurization flange, and the pressurization flange is connected with the clamp flange bolt, and clamp flange and outer sleeve are welded to connect.
Described guide-localization one ring, guide-localization two rings, guide-localization three rings are respectively the anti-corrosion bearing shells of steel loop liner.
Described core pipe is that outer wall of steel pipe is coated with the chromium layer.
Described core pipe fixed end design anticreep ring structure, promptly core pipe fixed end outer wall one has seam.
Described movable end stuffing box packing is that graphite packing and non-volatility are annotated packing packing material, and it is graphite or other filled non-volatility auxiliary material that adds that non-volatility is annotated packing packing material composition; The fixed end stuffing box packing is graphite packing and the conventional packing packing material of annotating, and conventional notes packing packing material composition is graphite or other filled adding to have certain volatile auxiliary material.
The utility model product adopts in two Seal cages when making and annotates packing packing material respectively, offers syrup filling tip having on the corresponding outer sleeve of certain volatile fixed end stuffing box packing in addition, in order to annotate stopping adjustment sealing by syrup filling tip.Because two roads sealings, and movable end pressurization flange can adjust movable end stuffing box packing gap, makes sealability improve greatly, prolonged the fixed end stuffing box packing material feeding time; Four guide-localization rings of design between two sealings (1 one ring, 2 two rings, 1 three ring) have improved location and steering capability between core pipe and outer sleeve; Four guide-localization rings adopt the anti-corrosion bearing shell of steel loop liner respectively, and anti-corrosion bearing shell closely contacts with the core pipe, have improved that compensator is antiacid, the corrosion ability of medium such as alkali and seawater, the functional reliability and the working life of having improved product greatly; The core pipe adopts outer wall of steel pipe to be coated with hard chromium layers, has strengthened anticorrosion, the sealability of compensator; The design of core pipe fixed end one anticreep ring structure has improved the ability that product meets accidental contingencies, and can guarantee the network security operation; The nonelastic power of compensator during work, fixed support thrust is little; The stuffing box packing of function admirable and advanced injection technique guarantee that product seals reliably; The design of syrup filling tip can be implemented in after-teeming under the pipe network operation state, and maintenance does not stop production; The stuffing box packing rebound elasticity is good, and is ageing-resistant, once injects the working life that can guarantee more than 10 years; Material feeding is long at interval, reduces maintenance cost; Applied widely, Applicable media: hot water, steam, wet goods; Security of operation, bulk life time were more than 20 years.
