Abstract
The present invention discloses an on-line sleeve type compensator of leakage blocking with pressure, which comprises an inner tube, a bracket, a gag lever post, a sealing ring, a gland, sealing material, a spring, a bolt groupware, an outer tube and a taper pipe. The bracket is arranged on the outer wall on the left of the gland matched as clearance and connected with the gland by the gag lever post. 3-32 sealing material filling apertures are distributed equably on the outer wall of sealing cavity of the outer tube, radial via holes in the sealing material filling apertures prong wall of outer tube, have plug bolts on top and art bolts pronged laterally the radial via holes on the waist. The present invention supplies sealing material by sealing material filling apertures at the status of working to resume the prior structure sealing. The present invention supplying sealing material on-line is convenient, economic and credible, which fit for appliance of all kinds of specification sleeve compensation.
Description
Technical field
The present invention relates to a kind of compensation of pipeline device, but a kind of slip-type expansion joint of pressure sealing particularly.
Background technique
Slip-type expansion joint is a kind of simple in structure, compensation rate is big, bearing capacity is strong compensation of pipeline device commonly used, and the relative movement of pipe and outer tube realized the thermal distortion that institute's distribution pipes takes place is compensated or absorbs in its utilized.When the slip-type expansion joint of prior art used, the sealing material in being between pipe and the outer tube had normality mechanical wear, in case the sealing material wearing and tearing are excessive, sealing configuration just lost efficacy and leaked.Under the normal condition, do not allow in the industrial pipe network set excessive leakage take place fully easily cause security incident because leak.Then cost is bigger to shut down the maintenance of carrying out necessity, and some technological process does not even allow shutdown maintenance.Demand is a kind of in the engineering can press the slip-type expansion joint that replenishes sealing material at tape.
Summary of the invention
The present invention is primarily aimed at the deficiency that prior art can not press be replenished sealing material at tape, propose a kind of simple in structure, easy to manufacture, can from outer tube wall, in Seal cage, inject the online pressure sealing slip-type expansion joint that replenishes sealing material.
Online pressure sealing slip-type expansion joint, it comprises interior pipe, support, position-limited lever, seal ring, gland, sealing material, spring, bolt assembly, outer tube and reducer pipe.Described support casing is contained on the outer wall of inner tube in gland left side and is Spielpassung, and support is located by connecting by position-limited lever and gland.Described bolt assembly polyphone connects gland and spring, and the spring of pressurized promotes outer tube left side flange and keeps gland compressing sealing material.Improvements are: uniform 3～32 the sealing material inlets of Seal cage section outer wall that are in outer tube.Establish the tube wall that radial direction through hole runs through outer tube in the described sealing material inlet, the radial direction through hole top is provided with the plug bolt, and waist is provided with the technology screw that laterally runs through radial direction through hole.
The present invention's seal of tube chamber section outer wall outside is provided with 3～32 sealing material inlets, the interior threaded hole nominal size of sealing material inlet end and the join muzzle size of the online leak stopping bolt of quick-acting type.The technology screw diameter is more than or equal to the radial direction through hole diameter.Described sealing material is the high-purity flexible graphite packing.
The present invention compared with prior art has following good effect:
1, uniform 3～32 sealing material inlets on the seal of tube cavity outer wall outside can replenish sealing material from different directions, and this is simple in structure, easy to manufacture;
2, online additional sealing material processing ease avoids between non-turn(a)round shutdown maintenance to cause the economic loss of pipe network;
3, can online additional sealing material, can avoid taking place excess fully and leak, improved the Safety performance of industrial pipe network greatly.
Description of drawings
It shown in the accompanying drawing structural profile schematic representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
Online pressure sealing slip-type expansion joint shown in the drawings, pipe 1, support 2, position-limited lever 3, seal ring 4, gland 5, sealing material 6, spring 7, bolt assembly 8, outer tube 9 and reducer pipe 10 in it comprises.Described support 2 is sleeved on interior pipe 1 outer wall in gland 5 left sides and is Spielpassung, and support 2 is located by connecting by position-limited lever 3 and gland 5, and support 2 has effectively improved the motion of interior pipe 1 with respect to outer tube 9, reduces because of the skew of interior pipe 1 wearing and tearing to sealing material 6.Described bolt assembly 8 polyphones connect gland 5 and spring 7, and the elastic force of spring 7 promotes outer tube 9 left flanges and keeps compressing of 5 pairs of sealing materials 6 of gland.The utility model is at uniform 3～32 the sealing material inlets 9.1 of the Seal cage section outer wall of outer tube 9.Establish the tube wall that radial direction through hole runs through outer tube 9 in the sealing material inlet 9.1, the radial direction through hole top is provided with plug bolt 9.2, and waist is provided with the technology screw 9.3 that laterally runs through radial direction through hole.Present embodiment is the online pressure sealing slip-type expansion joint of bore 400mm, the Seal cage outer wall of its outer tube 9 is provided with 9 sealing material inlets 9.1, when online pressure sealing slip-type expansion joint leaks, screw technology screw 9.3 at first respectively, lay down plug bolt 9.2, the online plugging gun of external quick-acting type injects and replenishes sealing material 6, when injecting complement operation each time and finishing, screw in technology screw 9.3 earlier, lay down the online plugging gun of quick-acting type again, screw on plug bolt 9.2 at last.By online injecting sealing material 6, just recover the sealability of its original structure.The sealing material 6 that the present invention adopts is high-purity flexible graphite packings.
The present invention determines the quantity of sealing material inlet 9.1 according to interior pipe 1 internal diameter nominal size, and every increase by the 40～60mm of internal diameter just sets up 1 sealing material inlet 9.1.Uniform sealing material inlet 9.1 on outer tube 9 Seal cage section tube wall circumference, injecting sealing material 6 from different directions, help balanced sealing.Because the online additional sealing material of the present invention is convenient, economical, reliable, need not wait for the turn(a)round shutdown maintenance, reduce widely because of excess and leak possibility of accident occurrence, effectively improved the Security and the Economy of industrial pipe network.
