Abstract
The utility model belongs to the technical field of heat supply, and provides a compensator with a filler compacting structure, comprising an outer sleeve (1), a core cylinder (8) and a sealing structure between the outer sleeve (1) and the core cylinder (8), wherein the sealing structure comprises a combined sealing ring (2) which comprises an L-shaped pressing cover (5); the pressing cover (5) is provided with a hole where a compacting bolt (6) passes through; the compacting bolt (6) passes through the pressing cover (5), and the other end of the compacting bolt is integrally threaded to the flange of the outer sleeve (1); a combined compacting disc spring (7) is sleeved on the compacting bolt (6) and located between the nut of the compacting bolt (6) and the pressing cover, so as to form a filler compacting structure that the pressing cover (5) maintains a continuous compacting force to a sealing filler (3). In the utility model, the pressing cover of the sleeve compensator maintains a continuous compacting force to the sealing filler, so that the safety, stability and long period running of a heat-supply network are ensured.
Description
Technical field
The utility model belongs to pipe connector, relates generally to a kind of compensator with filler compressing structure.
Background technique
Along with the fast development of concentrated supply of heating in the city, also more and more higher to the performance requirement of sleeve expansion joint, because the sealing problem of sleeve expansion joint not only relates to energy-conservation and pollution, and be related to the safety in production and the long-term operation of district heat supply network.
Sleeve expansion joint mainly uses packing seal, packing seal is a kind of contact seal, inserts elaxtic seal between outer sleeve and core pipe, can be close to the core tube-surface after filler is subjected to axial force and compresses, utilize the wearing and tearing of the resiliently deformable compensating sealing surface of sealing material, stop medium to leak outside.After using a period of time, when sleeve expansion joint caused sealing effect to weaken along with the increase of work cycle number of times because of wearing and tearing, the method that adopts for the sealability of reinforcing filler had three kinds: the one, and clamp flange hold-down bolt once more; The 2nd, sleeve expansion joint design can pouring-in filler device, and sealing compound injects from the material feeding port depended on pressure, and packing cavity pressure is raise, and reaches sealing effect.The 3rd, Gland adopts post spring precompression device, by the precompression of spring, makes stuffing box packing keep certain impacting force.Preceding two kinds of methods need manual maintenance, and the shortcoming of a kind of method in back is to adopt the post spring compression, make sleeve expansion joint boundary dimension strengthen complex structure.
Summary of the invention
The purpose of this utility model is to propose a kind of compensator with filler compressing structure, makes in the sleeve expansion joint working procedure filler is kept a kind of lasting impacting force, ensures that safe, steady, the long-term operation of heating network provides.
The utility model is finished the technological scheme that its invention task taked:
A kind of compensator with filler compressing structure, constitute by the sealing configuration between outer sleeve, core tube and outer sleeve, the core tube, sealing configuration has combined seal ring, has a gland, described gland is " L " shape, on gland, has the hole that hold-down bolt passes, described hold-down bolt passes gland, the other end one that is threaded with the flange of outer sleeve, combination compresses the dish spring and is enclosed within on the hold-down bolt and between the nut and gland of hold-down bolt, constitutes gland keeps the impacting force that continues to stuffing box packing filler compressing structure.
A kind of compensator filler compressing structure that the utility model proposes, make the sleeve expansion joint gland keep the impacting force that continues to stuffing box packing, the equilibrant force of dish spring then increases along with the increase of hold-down bolt pretightening force, can reach effective pretension, ensure safe, steady, the long-term operation of heating network.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the schematic representation of the utility model packing filling compressing structure.
Among the figure: 1, outer sleeve, 2, combined seal ring, 3, packing filling, 4, middle gland, 5, gland, 6, hold-down bolt, 7, combination compresses the dish spring, 8, the core tube.
Embodiment
With embodiment the utility model is further specified in conjunction with the accompanying drawings:
As shown in Figure 1, a kind of compensator with filler compressing structure, constitute by the sealing configuration between outer sleeve 1, core tube 8 and outer sleeve, the core tube, sealing configuration has combined seal ring 2, combined seal ring 2 arranged outside of being close to the bearing ring of outer sleeve have middle gland 4, in the chamber between middle gland 4 and the core tube 8 packing filling 3 is set, packing filling 3 compresses by gland 5, constitutes the sealing configuration of compensator.
As shown in Figure 2, gland 5 is " L " shape, have the hole that hold-down bolt 6 passes on gland 5, described hold-down bolt 6 passes gland 5, the other end one that is threaded with the flange of outer sleeve 1, and combination compresses dish spring 7 and is enclosed within on the hold-down bolt 6 and between the nut and gland of hold-down bolt 6; Combination compresses dish spring 7 by hold-down bolt 6 guiding, helps making up compressing dish spring 7 by the impacting force that 3 maintenances of 5 pairs of packing fillings of gland continue, and remedies packing filling 3 because the leakage that core tube skimming wear may cause.
Claims (1)
1. compensator with filler compressing structure, by outer sleeve (1), core tube (8) and outer sleeve (1), sealing configuration between the core tube (8) constitutes, sealing configuration has combined seal ring (2), it is characterized in that: have a gland (5), described gland (5) is " L " shape, on gland (5), has the hole that hold-down bolt (6) passes, described hold-down bolt (6) passes gland (5), the other end one that is threaded with the flange of outer sleeve (1), combination compresses dish spring (7) and is enclosed within hold-down bolt (6) and goes up and be positioned between the nut and gland of hold-down bolt (6), constitutes gland (5) keeps the impacting force that continues to stuffing box packing (3) filler compressing structure.
