Description
Technical field
The utility model is related to welding technology field, more particularly to a kind of rotatable annular flame heater.
Background technology
The process meanses that butt-welding fitting entirety or welding region are locally heated before weldering are referred to as preheating.For weld strength level
The not higher, steel that have tendency of hardenability, the heat conductivility especially larger weldment of good material, thickness, and work as welding region
Butt-welding fitting is generally required when ambient temperature is too low, before weldering to be preheated.The main purpose of preheating is reduction welding point
Cooling velocity, prevents that joint from generating hardened structure, produces cold crack.
In the steel construction of ocean engineering, most products are the form such as chunk and jacket, pipe spreading welding job amount compared with
Greatly, welding preheating is particularly important.In the prior art, by way of manual operation carry out weld preheating exist pre-heat effect difference and
The problem of efficiency is low, and working strength is especially big.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of rotatable annular flame heating
Device, with simple in construction and operation easily advantage, can effectively solve the problem of pre-heat effect is poor, favorably improve production efficiency
With it is cost-effective.
The utility model solve technical scheme that its technical problem used for：A kind of rotatable annular flame heating
Device, including support and the main gas tube that is rotatably erected on support, the main gas tube are one end sealing, other end conducting
Cylinder structure, conducting one end of the main gas tube is connected with valve, and the valve is used for external combustion gas, the main gas tube
Same circumference on uniformly offer nozzle be correspondingly arranged on several fabrication holes, each fabrication hole, the nozzle is pipe
Type structure, the main gas tube is connected with each nozzle.
Further, the fabrication hole is provided with four, and the nozzle is provided with four.
Further, the bottom of the support is a rectangular base, and the top of the support is two separate semicircles
Support, each semicircle support is fixedly connected in rectangular base by support bar, and one is formed between two semicircle supports and is available for nozzle to rotate
Space.
Further, the nozzle is arranged on fabrication hole by the form of angle welding.
Further, it is provided with and is drawn for increasing the fixed of intensity by the form of angle welding between the nozzle and nozzle
Muscle.
Further, the main gas tube, which is turned on, is provided with internal thread on the port of one end.
Further, the nozzle, fixed lacing wire, support and main gas tube are steel construction.
The beneficial effects of the utility model have：When actually used, first this annular flame heater is placed in bore,
By valve external pipe liquid gas, valve switch is opened, each nozzle is lighted, main gas tube is rotated, main gas tube drives nozzle
Rotation just can realize preheating, with simple in construction and operation easily advantage, and the problem of can effectively solving pre-heat effect difference has
Profit improves production efficiency and cost-effective.
Brief description of the drawings
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail, wherein：
Fig. 1 is the front view of the utility model annular flame heater；
Fig. 2 is the side view of the utility model annular flame heater.
Embodiment
Referring to Fig. 1 and Fig. 2, Fig. 1 is the front view of the utility model annular flame heater, and Fig. 2 is the utility model ring
The side view of shape fired heater.A kind of rotatable annular flame heater, including support 3 and rotatably it is erected at support
Main gas tube 4 on 3, the main gas tube 4 be one end seal, the cylinder structure of other end conducting, the main gas tube 4 leads
Logical one end is connected with valve 5, and the valve 5 is used for external combustion gas, if uniformly being offered on the same circumference of the main gas tube 4
Be correspondingly arranged on nozzle 1 on a dry fabrication hole, each fabrication hole, the nozzle 1 is cylinder structure, the main gas tube 4 with
Each nozzle 1 is connected.Specifically, the fabrication hole is provided with four, and the nozzle 1 is provided with four；The main gas tube 4 is led
Internal thread, convenient access combustion gas interface are provided with the port of logical one end.
When actually used, first this annular flame heater is placed in bore, by the external pipe combustion gas of valve 5,
Open valve 5 to switch, light each nozzle 1, rotate main gas tube 4, main gas tube 4, which drives nozzle 1 to rotate, just can realize preheating,
With simple in construction and operation easily advantage, can effectively solve the problem of pre-heat effect is poor, it is favourable improve production efficiency and
It is cost-effective.In addition, this annular flame heater has multiple nozzles 1, heating surface (area) (HS is big, and preheating can be achieved by rotation,
Need not manually hand-held liquefaction flame gun again, effectively reduce cost of labor and alleviate labor intensity.
The nozzle 1 is arranged on fabrication hole by the form of angle welding, and fillet welding is passed through between the nozzle 1 and nozzle 1
