Description
Technical field
The invention belongs to sealing device, particularly relate to a kind of boiler tube end cap of protective atmosphere high temperature sintering resistance furnace.
Background technology
For preventing in the boiler tube sintered body oxidation at high temperature even the charcoal phenomenon occurring taking off; protective atmosphere high temperature sintering resistance furnace under the duty must charge into inert gas in its boiler tube, therefore require the end cap of boiler tube should have excellent sealing performance under hot conditions.
End cap in the known technology is made up of base, intermediate sleeve and capping three parts, and wherein intermediate sleeve is connected with whorl of base, and capping and intermediate sleeve are fastening by screw.Base is subjected in the intermediate sleeve crimp of bead arc-shaped concave to be fixed in the boiler tube end by bead sealing ring in it, makes this sealing simultaneously.The composition surface of base and intermediate sleeve, intermediate sleeve and capping is provided with sealing ring respectively.In addition, be provided with the ring pipe of recirculated cooling water in the hugging of intermediate sleeve, the intermediate sleeve outside is provided with the port of ring pipe Inlet and outlet water.Facts have proved that the sealing effectiveness of above-mentioned end cap particularly at high temperature sealing effectiveness is unreliable, its reason is manually to rotate intermediate sleeve and makes it and base fluid-tight engagement difficulty comparatively, causes bead sealing ring distortion in the base not enough and cause the leakage of protective atmosphere.Also contact the slit and influence cooling-down effect, cause the end cap hot-spot, make the coefficient of expansion of each building block of end cap difference occur, cause joint gap to increase and make the protective atmosphere leakage owing to the ring pipe of recirculated cooling water and the hugging of intermediate sleeve exist.
Summary of the invention
The present invention is in order to solve the insecure technical problem of sealing effectiveness that known protective atmosphere high temperature sintering resistance furnace boiler tube end cover structure exists, and a kind of boiler tube end cap of sealing effectiveness reliable protection atmosphere high temperature sintering resistance furnace is provided.
The present invention takes following technical scheme for the above-mentioned technical problem that solves known protective atmosphere high temperature sintering resistance furnace boiler tube end cover structure existence: this end cap is made of base, intermediate sleeve and cover plate, base is provided with the corresponding through hole of screw that is symmetrically distributed with intermediate sleeve, each through hole be provided with correspondence be engaged in the intermediate sleeve screw, make the trip bolt of base fluid-tight engagement in intermediate sleeve; Intermediate sleeve is provided with water annulus, and its cylindrical ring wall is arranged with the cooling water water inlet pipe and water outlet pipe that communicates with it.
The present invention can also take following technical measures:
The interior bead on described intermediate sleeve and base composition surface is provided with the groove of compacting sealing ring.
The cooling water inlet tube and outlet tube of described intermediate sleeve under its user mode is vertical the setting, and wherein water inlet pipe is positioned at the intermediate sleeve bottom side.
Beneficial effect of the present invention and advantage are; The intermediate sleeve of this end cap is to utilize instrument to screw realization by trip bolt with engaging of end seat, more manually screw reliable for effect, make when screwing and be arranged on the fully distortion under the extruding of intermediate sleeve groove of the sealing ring between the bead and boiler tube in base and the intermediate sleeve composition surface, thereby base is fixed in boiler tube firmly and makes this positiver sealing, also make simultaneously between base and the intermediate sleeve sealing ring this junction surface positiver sealing.The set water annulus of the intermediate sleeve of this end cap is compared the bigger and contactless slit of its sectional area with horizontally-arranged ring pipe wherein, therefore the water-cooled cooling effect makes end cap at high temperature can keep stable sealing property significantly better than the cooling water circulation ring pipe in the known technology.The present invention has good sealing effect, can reduce or avoid the sintered body oxidation effectively and take off the generation of charcoal phenomenon.
