Abstract
The utility model provides a bidirectional self-sealing sleeve compensator which comprises two inner core tubes and a shell body. Two ends of the shell body are respectively provided with outer limit flanges, and gland flanges are arranged on external sides of the outer limit flanges. Sealing materials are filled inside the closed space formed by the shell body, the gland flanges and the inner core tubes. The outer limit flange and the gland flange on the same side are fixed through bolts. A material ejecting device communicated with the sealing materials is arranged on the shell body. The bidirectional self-sealing sleeve compensator is big in compensation dosage, small in resistance, simple in structure, small in occupied space, simple to install, and convenient to maintain, achieves leakage blocking with pressure, and can achieve the supplement of sealing materials without shutting down a machine.
Description
Technical field
The utility model relates to a kind of pipe line compensating device, is specifically related to a kind of two-way selfsealings sleeve expansion joint.
Background technique
In order to solve the length change of heat supply pipeline because expanding with heat and contract with cold and producing, often use various compensation devices, such as the FlexbleJoint that often uses at present, ball compensator and square-shaped joints etc.But these compensators have self-defect owing to its structural reason, and are little such as the compensation rate of corrugated expansion joint, and thrust is large and price is high.The ball compensator pressure-bearing is low, floor space is large; The various parts not fully up to expectations such as the built on stilts installation of square-shaped joints is attractive in appearance not, and the not manageability of exitting that discharges water, and underground installation floor space is large.In general, lack a kind of compensation rate large, take up an area the little and safe and reliable compensator in space.
The model utility content
The purpose of this utility model is the problem that exists for prior art, provide a kind of compensation rate large, take up an area the little and safe and reliable two-way selfsealings sleeve expansion joint in space.
For this reason, the utility model adopts following technological scheme:
A kind of two-way selfsealings sleeve expansion joint, comprise two inner core tube and a housing, the two ends of described housing are respectively equipped with outer spacing flange, and the outside of described outer spacing flange is provided with gland flange, are filled with sealing material in the confined space that housing, gland flange and inner core tube form; Between the outer spacing flange of the same side and gland flange, be bolted.
Be socketed with spacing flange in two on the described housing, described interior spacing flange and between the outer spacing flange of its homonymy and gland flange, being bolted, and be set with spring on the screw rod between interior spacing flange and the outer spacing flange.
Be respectively equipped with on described two inner core tube and tighten up flange, described tightening up between flange and the gland flange is bolted.
Described housing is provided with the material injecting device that is connected with sealing material.More than one of described material injecting device, and along radially evenly distribution of housing.
Described material injecting device comprises material hole, plug screw and revolves only screw, describedly only revolves that screw runs through the setting of material hole waist, and revolves the diameter of screw only more than or equal to the internal diameter of material hole.
Described sealing material is graphite.
Inner core tube can realize moving at both direction in the utility model, thereby the utility model compensator has the large characteristics of compensation rate; Employing tightens up the stability that the fastening piece such as flange, bolt have increased the utility model structure; It is good that graphite has a self lubricity, rebound degree, compressible height, the advantages such as corrosion resistance is strong, especially its impermeability is so that the sealing of compensator is stronger, this does not allow to stop the pipeline of heat supply for some, such as food processing, the heat supply pipeline of chemical engineering industry, petroleum delivery pipeline and important district for foreign missions has important practical significance; And the utility model is simple in structure, and annex is few, saves the space.
To sum up, the beneficial effects of the utility model are: compensation rate is large, and resistance is little; Simple in structure, the occupation of land space is little, installs simple, easy to maintenance; Pressure sealing can be realized, replenishing of sealing material can be in not shutdown situation, realized.
Description of drawings
Fig. 1 is cross-sectional view of the present utility model.
Embodiment
As shown in Figure 1, a kind of two-way selfsealings sleeve expansion joint, comprise two inner core tube 1 and a housing 2, the two ends of housing 2 are respectively equipped with outer spacing flange 3, be provided with again spacing flange 5 in two between the two outer spacing flanges 3, the outside of two outer spacing flanges 3 is respectively equipped with gland flange 4, is filled with sealing material 13 in the confined space that housing 2, gland flange 4 and inner core tube 1 form; Fixing by bolt 8 between the interior spacing flange 5 of the same side, outer spacing flange 3 and gland flange 4, the nut of bolt 8 is located at the outside of interior spacing flange 5 and gland flange 4, is set with spring 6 on the screw rod between interior spacing flange 5 and the outer spacing flange 3; Be respectively equipped with on two inner core tube 1 and tighten up flange 7, tighten up between flange 7 and the gland flange 4 fixing by bolt 9;
Also be provided with the material injecting device that is connected with sealing material 13 on the housing 2, this material injecting device comprises material hole 11, plug screw 10 and revolves only screw 12, revolve only that screw 12 runs through the waist setting of material hole 11, and revolve the diameter of screw 12 only more than or equal to the internal diameter of material hole 11; This material injecting device is a plurality of and radially evenly distributes along housing 2.Sealing material 13 is selected high purity graphite in the utility model.
During the utility model sleeve expansion joint compensation operation, inner core tube 1 can be in the movement of housing 2 interior realization both directions.When inner core tube 1 is moved, because the effect of contraction of bolt 8 and spring 6, and the effect that tightens up that tightens up flange 7 and bolt 9, the displacement amount of inner core tube 1 is restricted, and has guaranteed the reliability of compensating sleeve.In addition, when replenishing sealing material 13, can be under spiral shell in the not shutdown situation plug screw 10, only will revolve that screw 12 spiral shells go out, replenish sealing materials by material hole 11, thereby realize the online with pressure additional of the utility model sealing material.
