Abstract
The utility model relates to a high-pressure replaceable eclectic heater assembly, which is used for heating natural gas or other gases by being installed into an electric heater. The high-pressure replaceable eclectic heater assembly comprises electric heating tubes, an electric heating tube fixed plate, an outer screw thread sealed connecting head, a compressed nut, a sealing sleeve (1) and a sealing sleeve (2) and the high-pressure replaceable eclectic heater assembly is characterized in that the sealing sleeve (1) and the sealing sleeve (2) both with elasticity are installed inside the compressed nut. When the compressed nut is screwed, the sealing sleeve (1) and the sealing sleeve (2) are tightly clamped on the outer circular walls of the electric heating tubes to produce sealing functions, thereby enabling a cylinder body of the electric heater to be in a high-pressure state. When one electric heating tube is damaged after certain time of usage, a user only need to unscrew the compressed nut to loosen the sealing sleeve (1) and the sealing sleeve (2) from the outer circular walls of the electric heating tubes, thereby each single electric heating tube can be disconnected and replaced without causing damage and the outer screw thread sealed connecting head, the electric heating tube fixed plate and undamaged electric heating tubes can be preserved. Further, the compressed nut, the sealing sleeve (1) and the sealing sleeve (2) are capable of being reused for multiple times, each time disconnection and replacement of electric heating tubes can save three fourths of total costs of the overall electric heater, and fine sealing and convenient disconnection and replacement are achieved.
Description
Technical field
The utility model is a kind of high-voltage detachable electric heater component that natural gas or other gas are used that heats.
Background technology
Natural gas or other gas are carried in pipeline, when ambient temperature is low, must the temperature of natural gas or other gas be kept within the specific limits to natural gas or the heating of other gas, increase its flowability, are convenient to carry.Heating natural gas or other gas are used electric heater usually, and concise and to the point operation principle is: natural gas or other gas enter in the electric heater cylindrical shell from inlet flange, and along the deflector direction, through electrothermal tube, elevated temperature, flange is gone out from giving vent to anger.Core component in the electric heater is an electric heater component, is made up of electrothermal tube fixed head and some electrothermal tubes.Pressure during operate as normal in the electric heater cylindrical shell is higher, reaches 9MPa-10MPa.For guaranteeing that electric heater integral body has excellent sealing performance, original technical scheme is: some electrothermal tubes are welded on the electrothermal tube fixed head, form electric heater component, it is connected with the electric heater cylindrical shell with sealing gasket by shell flange.Electrothermal tube is a consumable accessory, but can all not damage simultaneously, behind the use certain hour, when one or a few electrothermal tube generation damage needs to change, can not be single harmless changeing must be changed all electrothermal tubes together with electrothermal tube fixed head integral body, cause the waste of material and production costs.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of electric heater component is provided, abbreviate high-voltage detachable electric heater component as, electrothermal tube is not to be welded on the electrothermal tube fixed head, and be mounted in inside the external screw thread seal nipple, produce sealing function by sealing shroud (), sealing shroud (two), make in the electric heater cylindrical shell to keep high pressure.After one or a few electrothermal tube damages, can carry out single harmless changeing, keep external screw thread seal nipple, electrothermal tube fixed head and unspoiled electrothermal tube.
For solving the technical scheme that above technical problem adopts is such: an end of thread seal joint outside is rotary with clamp nut.In the clamp nut the inside, rubber-like sealing shroud (), sealing shroud (two) are installed.The external screw thread seal nipple is welded on the electrothermal tube fixed head.When screwing clamp nut, sealing shroud (once), sealing shroud (two) is clamped on the electrothermal tube cylindrical wall, produces sealing function, make to keep high pressure in the electric heater cylindrical shell.When certain root electrothermal tube and after damaging through using after a while, as long as unscrew clamp nut, sealing shroud (one), sealing shroud (two) will unclamp from electrothermal tube cylindrical wall, that root electrothermal tube that damages just can be taken out from external screw thread seal nipple, sealing shroud (), sealing shroud (two) easily, changes, installs a new electrothermal tube.Clamp nut, sealing shroud (), sealing shroud (two) can be repeatedly used.
Because adopt above technical scheme, its effect is conspicuous:
1, cost saving.The total expense of some electrothermal tubes in the electric heater, these two part materials of electrothermal tube fixed head and making accounts for 3/4ths of electric heater complete machine total value, adopt this high-voltage detachable electric heater component, whenever change electrothermal tube one time, just can save the expense of 3/4ths electric heater complete machine total value.
2, good seal.The sealing effectiveness of high-voltage detachable electric heater component is equal to the sealing effectiveness of former technical scheme electric heater component, keeps the high pressure in the electric heater cylindrical shell.
3, change conveniently.
Description of drawings
Fig. 1 is the electric heater structure diagram of original technical scheme.
Fig. 2 is the electric heater structure diagram of high-voltage detachable electric heater component.
Among the figure: 1, give vent to anger flange 2, deflector 3, cylindrical shell 4, inlet flange 5, shell flange 6, sealing gasket 7, electrothermal tube fixed head 8, electrothermal tube 9, external screw thread seal nipple 10, clamp nut 11, sealing shroud () 12, sealing shroud (two)
The specific embodiment
With reference to Fig. 1, Fig. 2, the utility model is a kind of high-voltage detachable electric heater component, and electrothermal tube 8 packs into clamp nut 10, sealing shroud () 11, sealing shroud (two) 12, external screw thread seal nipple 9 the insides.The external screw thread seal nipple is welded on above the electrothermal tube fixed head 7.When screwing clamp nut, sealing shroud (once), sealing shroud (two) is clamped on the cylindrical wall of electrothermal tube, produces sealing function.When unscrewing clamp nut, sealing shroud (once), unclamp on the cylindrical wall of sealing shroud (two) at electrothermal tube, electrothermal tube can be taken out from external screw thread seal nipple, sealing shroud (), sealing shroud (two), clamp nut, can't harm and change reservation external screw thread seal nipple, electrothermal tube fixed head and unspoiled electrothermal tube.
Claims (3)
1, a kind of high-voltage detachable electric heater component, this electric heater component comprises electrothermal tube (8), external screw thread seal nipple (9), clamp nut (10), sealing shroud () (11), sealing shroud (two) (12), it is characterized in that: the clamp nut the inside, rubber-like sealing shroud (one) (11), sealing shroud (two) (12) are installed, when screwing clamp nut, sealing shroud (one), sealing shroud (two) will be clamped on the electrothermal tube cylindrical wall, when unscrewing clamp nut, sealing shroud (), sealing shroud (two) will unclamp from electrothermal tube cylindrical wall.
