Abstract
The utility model discloses a gas heater, comprising a heater body (1), a power connecting line (5) and a cover (2) detachably connected with the heater body (1). A heating pipe (6), a hollow gas inlet joint (3) and a hollow gas outlet joint (4) are arranged on the heater body (1), One end of the heating pipe (6) is communicated with the gas inlet joint (3), and the other end of the heating pipe (6) is communicated with the gas outlet joint (4). A heating unit is connected on the heating pipe (6) to heat the heating pipe (6), and is electrically connected with the power connecting line (5). The gas heater prevents protective gas for gas-protection arc welding from forming frost so as not to block a pipeline.
Description
Technical field
The utility model relates to the welding and cutting device technical field, specifically is a kind of gas heater.
Background technology
At present, gas shielded arc welding generally adopts gas-insulated atmosphere such as argon or carbon dioxide, and electric arc and molten bath rate during with the protection welding are to improve welding quality.The gas shielded arc welding of prior art is when welding; The steel cylinder that high-pressure carbon dioxide gas is housed feeds the carbon dioxide of low pressure the tip portion of gas shielded arc welding through pipeline through gas pressure reducer; The carbon dioxide gas temperature of low pressure is lower; When flowing through pipeline, if the temperature of pipeline is higher than the temperature of carbon dioxide, carbon dioxide can produce at the inwall of pipeline when flowing through pipeline and coagulate frost and make line clogging so.
The utility model content
The technical problem that the utility model will solve is, overcomes the defective of above prior art, provides a kind of protective gas of gas shielded arc welding that makes can not produce the gas heater that coagulates white blocking pipe.
The technical solution of the utility model is; A kind of gas heater with following structure is provided: it comprise heater body, power supply wiring with the removable case that is connected of heater body; Described heater body is provided with the inlet suction port of heating tube, hollow and the air outlet adapter of hollow; One end of said heating tube is connected with inlet suction port; The other end of heating tube is connected with air outlet adapter, is connected with the heater to the heating tube heating on the said heating tube, and described heater is electrically connected with power supply wiring.
After adopting above structure; The utility model gas heater compared with prior art; Have the following advantages: during protective gas such as the interior logical carbon dioxide of the heating tube of this gas heater; The heater energising makes heater heat to heating tube, after heating tube is heated and heats up the interior protective gas temperature such as carbon dioxide of heating tube is raise, and the protective gas such as carbon dioxide of low pressure just can not produce and coagulate frost obstruction breather line like this.
As preferably, described heater comprises heating plate and temperature controller, and described heating plate and temperature controller are installed on the outer wall of heating tube, and temperature controller is connected through lead with the conductive junction point of heating plate.Described temperature controller can be set heating-up temperature, and like 75～85 degree, temperature controller automatic disconnection circuit stops heating plate heating, very easy to use, safety when the temperature of heating plate is spent above 85.
As preferably, the crooked S-shaped setting of described heating tube.The heating tube that S shape is provided with can make the protective gas that passes through fully heat homogeneous heating.
As a kind of improvement, on the said heater body indicator lamp is installed.Described indicator lamp is opened when heater heats, and extinguishes when stopping to heat.
