Abstract
The invention relates to a high-pressure detachable type electric heating component, which is arranged in an electric heater for heating the natural gas or other gases. The electric heating component comprises electrothermal tubes, an electrothermal tube fixing plate, an external thread sealing joint, a compression nut, a first sealing bush and a second sealing bush. The electric heating component is characterized in that the inside of the compression nut is provided with the first elastic sealing bush and the second elastic sealing bush. When the compression nut is tightly screwed, the first sealing bush and the second sealing bush are clamped on the excircle walls of the electrothermal tubes to achieve a sealing effect and to ensure that the inside of a cylinder of the electric heater is always in a high-pressure state. When an electrothermal tube is damaged after being used for a period of time, the first sealing bush and the second sealing bush can be loosened from the excircle walls of the electrothermal tubes only by loosening the compression nut. The heating tubes can be individually detached and changed without damage. The outer thread sealing joint, the electrothermal tube fixing plate and the undamaged electrothermal tubes are maintained. The compression nut, the first sealing bush and the second sealing bush can be repeatedly used for multiple times. The expense of three quarters of the total value of the electric heater can be saved during detaching the electrothermal tube each time. The electric heating component has the advantages of good sealing and convenient detaching and replacement.
Description
Technical field
The present invention heats the high-voltage detachable electric heater component that rock gas or other gas are used for a kind of.
Background technique
Rock gas or other gas are carried in pipeline, when external temperature is low, must the temperature of rock gas or other gas kept within the specific limits to rock gas or other gas heating, increase its flowability, are convenient to carry.Heating rock gas or other gas are used electric heater usually, and concise and to the point working principle is: rock gas or other gas get in the electric heater cylindrical shell from inlet flange, and along the guide plate direction, through electric heating 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 electric heating tube fixed plate and some electric heating tubes.Pressure during proper functioning in the electric heater cylindrical shell is higher, reaches 9MPa-10MPa.For guaranteeing that electric heater integral body has excellent sealing performance, original technological scheme is: some electric heating tubes are welded on the electric heating tube fixed plate, form electric heater component, it is connected with the electric heater cylindrical shell with sealing gasket through shell flange.Electric heating tube is an easily damaged parts, but can all not damage simultaneously, behind the use certain hour; When one or a few electric heating tube generation damage needs to change; Can not be single harmless changeing must be changed all electric heating tubes together with electric heating tube fixed plate integral body, cause the waste of material and production costs.
Summary of the invention
Technical problem to be solved by this invention is: a kind of electric heater component is provided; Abbreviate high-voltage detachable electric heater component as; Electric heating tube is not to be welded on the electric heating tube fixed plate; And be mounted in inside the outside thread SEALING FITTING, lean on first stuffing box gland, second stuffing box gland to produce seal action, make in the electric heater cylindrical shell to keep high pressure.After one or a few electric heating tube damages, can carry out single harmless changeing, keep outside thread SEALING FITTING, electric heating tube fixed plate and unspoiled electric heating tube.
For solving the technological scheme that above technical problem adopts is such: an end of thread seal joint outside is rotary with gland nut.In the gland nut the inside, rubber-like first stuffing box gland, second stuffing box gland are installed.The outside thread SEALING FITTING is welded on the electric heating tube fixed plate, and gland nut and outside thread SEALING FITTING are complementary, and gland nut is screwed easily on the thread seal joint outside or unscrewed.When screwing gland nut, first stuffing box gland, second stuffing box gland will be clamped on the electric heating tube cylindrical wall, produce seal action, make to keep high pressure in the electric heater cylindrical shell.When certain root electric heating tube and after damaging through using after a while; As long as unscrew gland nut; First stuffing box gland, second stuffing box gland will unclamp from electric heating tube cylindrical wall; That root electric heating tube that damages just can be taken out from outside thread SEALING FITTING, first stuffing box gland, second stuffing box gland easily, changes, installs a new electric heating tube.Gland nut, first stuffing box gland, second stuffing box gland can be repeatedly used.
Because adopt above technological scheme, its effect is conspicuous:
1, cost saving.The total expense of some electric heating tubes in the electric heater, these two part materials of electric heating tube fixed plate and making accounts for 3/4ths of electric heater complete machine total value; Adopt this high-voltage detachable electric heater component; Whenever change electric heating tube one time, just can save the expense of 3/4ths electric heater complete machine total value.
2, good seal.The sealing effect of high-voltage detachable electric heater component is equal to the sealing effect of former technological 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 technological 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, guide plate 3, cylindrical shell 4, inlet flange 5, shell flange 6, sealing gasket 7, electric heating tube fixed plate 8, electric heating tube 9, outside thread SEALING FITTING 10, gland nut 11, first stuffing box gland 12, second stuffing box gland
Embodiment
With reference to Fig. 1, Fig. 2, the present invention is a kind of high-voltage detachable electric heater component, and electric heating tube 8 packs into gland nut 10, first stuffing box gland 11, second stuffing box gland 12, outside thread SEALING FITTING 9 the insides.The outside thread SEALING FITTING is welded on above the electric heating tube fixed plate 7.When screwing gland nut, first stuffing box gland, second stuffing box gland will be clamped on the cylindrical wall of electric heating tube, produce seal action.When unscrewing gland nut; First stuffing box gland, second stuffing box gland just unclamp on the cylindrical wall of electric heating tube; Electric heating tube can be taken out from outside thread SEALING FITTING, first stuffing box gland, second stuffing box gland, gland nut; Can't harm and change reservation outside thread SEALING FITTING, electric heating tube fixed plate and unspoiled electric heating tube.
