Description
Technical field
The utility model belongs to end socket piece weld heating technical field, relates to a kind of end socket piece weld heating device.
Background technology
At present, while heating before the welding of end socket piece, conventionally adopt simple frock, the combustion of natural gas straight contact is heated workpiece; Exist gas utilization factor not high, very easily cause the inhomogeneous problem of heating, and because burning is insufficient, surface of the work is polluted, affect weldquality.
Summary of the invention
The purpose of this utility model is to provide a kind of end socket piece weld heating device, and homogeneous heating workpiece when end socket piece welds improves gas utilization factor, improves weldquality simultaneously.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of end socket piece weld heating device, the housing that comprises cuboid, on one group of sidewall of housing, be processed with respectively a plurality of passages, a sidewall in another group sidewall of housing is provided with a plurality of flame-thrower nozzles, an end cap of housing is provided with the breather pipe of one end sealing, the blind end of breather pipe stretches in housing, the other end of breather pipe stretches out outside housing, and be communicated with valve, the axis direction processing quantity fumarole identical with flame-thrower nozzle quantity along breather pipe, and fumarole forms corresponding one by one with flame-thrower nozzle, corresponding fumarole and flame-thrower nozzle coaxially arrange.
The utility model heater adopt be provided with flame-thrower nozzle and breather pipe housing, after being mixed in housing, natural gas and air spray from flame-thrower nozzle, overcome the defect of single-point heating source flame heating, be arranged in the suitable distance of whole end socket piece weld seam, energy butt welded seam homogeneous heating, and convenient simultaneously to the construction of other associated part, movement.Tool has the following advantages:
1) front preheating and the rear after heat of welding are welded in end socket splicing welding joint position, simple, convenient;
2) reasonably topology layout, contributes to obtain good air-breathing, and natural gas and air degree of mixing are good, burn more abundant, can save a large amount of natural gases;
3) convenient, flexible valve mechanism, can more accurately control the length of flame and uniformity easily.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model end socket piece weld heating device.
Fig. 2 is the top view of the utility model end socket piece weld heating device.
In figure: 1. housing, 2. right baffle plate, 3. right baffle-plate, 4. overhead gage, 5. breather pipe, 6. flame-thrower nozzle, 7. fumarole, 8. passage, 9. valve.
The specific embodiment
Now by reference to the accompanying drawings, the utility model is described as follows:
As depicted in figs. 1 and 2, the utility model heater, the housing 1 that comprises the cuboid of hollow, on one group of sidewall that housing 1 is oppositely arranged, be processed with respectively a plurality of passages 8, housing 1 another group is oppositely arranged the flame-thrower nozzle 6 that a sidewall in sidewall is provided with a plurality of tubulars, one end of flame-thrower nozzle 6 is stretched in housing, and the other end of flame-thrower nozzle 6 stretches out outside housing 1, and all flame-thrower nozzles 6 are arranged in order along the axis direction of place sidewall; An end cap of housing 1 is provided with breather pipe 5, one end of breather pipe 5 is stretched in housing 1, and breather pipe 5 stretches into one end end face sealing in housing 1, the other end of breather pipe 5 stretches out outside housing 1, and be connected with valve 9, on breather pipe 5, be processed with successively a plurality of fumaroles 7 along the axis direction of breather pipe 5, the quantity of fumarole 7 is identical with the quantity of flame-thrower nozzle 6, and there is a flame-thrower nozzle 6 below of a fumarole 7, corresponding fumarole 7 and flame-thrower nozzle 6 coaxially arrange.
The diameter of fumarole 7 is 2～3mm, so that natural gas sprays with elevated pressures.
The manufacturing process of the utility model heater: select the channel-section steel of certain length as the main body of this heater; The right baffle plate 2 of Tig Welding and right baffle-plate 3 are by hand distinguished in the left and right sides at this channel-section steel, and right baffle plate 2 is provided with locating hole; On the top of channel-section steel 1, adopt GTAW welding overhead gage 4; Channel-section steel, right baffle plate 2, right baffle-plate 3 and overhead gage 4 form housing 1; Breather pipe 5 is opened locating hole and penetrated from right baffle plate 2, and adopt GTAW to be welded and fixed; By length, be that 60mm, diameter are that the flame-thrower nozzle 6 of Φ 40 adopts GTAWs to be welded on the locating hole place opening on overhead gage 4, the axiality that guarantees flame-thrower nozzle 6 and fumarole 7 is in ± 1mm; The unsealing end of breather pipe 5 is connected with valve 9.
In the time of need to carrying out the welding of end socket piece, the need welding end socket below that sidewall relative with being provided with flame-thrower nozzle 6 sidewalls on housing 1 is placed, makes flame-thrower nozzle 6 aim at end socket piece; The air inlet of valve 9 is communicated with natural gas line, opens valve 9, and regulate by valve 9 flow of controlling natural gas.Natural gas enters breather pipe 5 by valve 9, and with higher speed, spray to corresponding flame-thrower nozzle 6 from fumarole 7, circulation due to gas, making has had pressure differential inside and outside housing 1, forces air to enter in housing 1 from passage 8 with certain flow velocity, fully mixes with natural gas, form mist, then, this mist is met naked light from flame-thrower nozzle 6 ejections and is lighted, and end socket piece is heated.Because air and natural gas are after the interior abundant mixing of housing 1, by flame-thrower nozzle 6, spray, burning makes burning more abundant, and efficiency of combustion improves; Meanwhile, the flame-thrower nozzle 6 of setting makes centralized heat energy, can reach in the short period of time the heating-up temperature of expection.
