Abstract
The utility model discloses a welded junction heating thermal insulation device, which mainly solves the problems of poor heating thermal insulation effect, high damage possibility and high heating thermal insulation cost of the convention heating thermal insulation mode. The welded junction heating thermal insulation device is characterized in that inner shells (2) are fixed in bosses on the front and rear sides of two semi-circular outer shells (1); through holes are formed in the inner shells (2); the edge contact position between the outer shells (1) and the inner shells (2) is sealed by an asbestos rope; thermal insulation cotton (3) and a resistance wire (4) are fixed between the outer shells (1) and the inner shells (2) from outside to inside; a porcelain pipe is sleeved outside the resistance wire (4); a bimetallic thermometer is connected to the inner shells (2); and the right sides of the two outer shells (1) are hinged with each other, and the left sides of the two outer shells (1) are buckled with each other through a connecting buckle. The welded junction heating thermal insulation device has the characteristics of good heating thermal insulation effect and low heating thermal insulation cost and is easy to operate.
Description
Technical field
The utility model relates to the used attemperator of a kind of pipeline welding, especially weld bond heating warmer.
Background technology
In the pipeline welding field, need butt welded seam to be incubated after pipeline welding is intact.And the oxy-acetylene flame heating is generally adopted in existing weld seam insulation, the insulation quilt heat preserving mode, and there is the heat tracing weak effect in this mode, and is fragile, and the problem that the heat tracing cost is high influences pipeline welding quality and efficient.
Summary of the invention
In order to solve existing heat tracing mode heat tracing weak effect, fragile, the problem that the heat tracing cost is high.The utility model provides a kind of weld bond heating warmer.It is effective, simple to operate that this weld bond heating warmer has heat tracing, the characteristics that the heat tracing cost is low.
The technical scheme of the utility model is: this weld bond heating warmer comprises shell, inner casing, heat-preservation cotton and resistance wire.Be fixed with inner casing in the boss of both sides before and after the two halves circular housing; Through hole is arranged on the inner casing, and shell and inner casing EDGE CONTACT place seal with asbestos cord, and ecto-entad is fixed with heat-preservation cotton and resistance wire between shell and the inner casing; Resistance wire is with porcelain tube outward; Be connected with bimetallic thermometer on the inner casing, two shell right side phase hinges connect, and pass on left junction button and are connected.
The utlity model has following beneficial effect: this weld bond heating warmer is owing to be fixed with inner casing in the boss of both sides before and after the employing two halves circular housing; Ecto-entad is fixed with heat-preservation cotton and resistance wire between shell and the inner casing; Resistance wire is with porcelain tube outward; Two shell right side phase hinges connect, and pass on left the junction button structure that is connected.Utilize the heat-preservation cotton insulation, strengthen heat insulation effect, make simple to operate.Utilize resistance wire heating, the bimetallic thermometer displays temperature is strengthened heats, makes simple to operately, reuses, and reduces the heat tracing cost.It is effective, simple to operate that this weld bond heating warmer has heat tracing thus, the characteristics that the heat tracing cost is low.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 be among Fig. 1 A-A to profile.
1-shell among the figure, 2-inner casing, 3-heat-preservation cotton, 4-resistance wire.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing, this weld bond heating warmer comprises shell 1, inner casing 2, heat-preservation cotton 3 and resistance wire 4.Two shells 1 are semicircle; There is boss both sides, shell 1 front and back; Shell 1 boss inboard is fixed with heat-preservation cotton 3, and heat-preservation cotton 3 inboards are fixed with the outer resistance wire 4 that is with porcelain tube, and resistance wire 4 is connected with power supply through lead; Shell 1 is welded with one of ground terminal with inner casing 2, and one of supply socket is with pottery magnetic binding post.Resistance wire 4 inboards are fixed with inner casing 2, on the inner casing 2 through hole are arranged, and shell 1 seals with asbestos cord with inner casing 2 EDGE CONTACT places; Be connected with bimetallic thermometer on the inner casing 2; By the bimetallic thermometer displays temperature, two shells, 1 right side connects with rotating shaft phase hinge, passes on left two pinches of buttons and is connected.
During actual the use; Half of this weld bond heating warmer withheld on pipe welding seam; Rotation adds half again, and second half is withheld on pipe welding seam, through pinching button this weld bond heating warmer of two halves is connected together again; Last resistance wire 4 is connected with power supply through lead, promptly accomplishes the operation of pipe welding seam heat tracing.
This weld bond heating warmer is the firing rate of line up no matter, or heat insulation effect, with oxy-acetylene or liquefied gas flame heat all were greatly improved in the past.Reduce construction cost simultaneously, also guaranteed the weld bond construction quality.Need not the thermometric operation, improve work efficiency more than 2 times.Improve welding quality, reduce cost 1/3rd.
