The utility model solves the technical scheme that its technical problem adopts:
A kind of novel welded tube device, comprise silica tube, the outer wall of described silica tube is provided with electric heating unit, described electric heating unit forms high temperature welded tube district in described silica tube, described silica tube is provided with quartzy pipe cap in inherent high temperature welded tube district, the edge of described quartzy pipe cap and the inwall of described silica tube are fitted, and the mouth of pipe and the cutting ferrule junction of described silica tube are provided with the first O-ring seal, and described cutting ferrule is communicated with vacuum machine.
Preferably, be provided with between described quartzy pipe cap and described first O-ring seal and stagnantly move unit.
Preferably, the described stagnant unit that moves is quartz pushrod or quartzy cutting ferrule, and removable.
Preferably, described cutting ferrule is communicated with described vacuum machine by valve tube, and described cutting ferrule and described valve tube junction are provided with the second O-ring seal.
Preferably, electric heating unit is electrical heating wire, and described electrical heating wire is wrapped on the outer wall of described silica tube.
The beneficial effects of the utility model are: can avoid hydrogen when device of the present utility model carries out gallium arsenide synthesis, oxygen welding meets accident blast when connecing; Adopt Electric heating not need closely to operate, and silica tube can be made to be heated evenly, ensure operative employee's safety and silica tube resistance to air loss; Also avoid a large amount of hydrogen, carrier of oxygen is preserved, eliminate recessive potential safety hazard; Also adopt two seals cushion rubber, both ensured that the quartzy mouth of pipe was not damaged when vacuumizing, ensuring equipment resistance to air loss is good again; The stagnant unit that moves ensures that quartzy pipe cap does not depart from high temperature welded tube district, is conducive to welding operation; Greatly reduce energy consumption, save energy, reduce costs, reduce the incidence of security incident.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the front view of the utility model embodiment.
Mark in figure: 1-silica tube, 2-quartz pipe cap, 3-electric heating unit, 4-first O-ring seal, 5-cutting ferrule, 6-second O-ring seal, 7-valve tube, 8-vacuum machine, 9-is stagnant moves unit.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The novel welded tube device of one described in the utility model as shown in Figure 1, comprise silica tube 1, the outer wall of described silica tube 1 is provided with electric heating unit 3, described electric heating unit 3 forms high temperature welded tube district in described silica tube 1, this device adopts electrically heated mode, safety and silica tube 1 are heated evenly, ensure in silica tube 1 and seal completely, prevent arsenic from leaking, quartzy pipe cap 2 is provided with in described silica tube 1 inherent high temperature welded tube district, the edge of described quartzy pipe cap 2 and the inwall of described silica tube 1 are fitted, the mouth of pipe and cutting ferrule 5 junction of described silica tube 1 are provided with the first O-ring seal 4, described cutting ferrule 5 is communicated with vacuum machine 8, this device improves hydrogen, oxygen mix heating process, avoid the generation of accidental explosion accident, may cause when avoiding human weld's heated quarty tube 1 be simultaneously heated uneven, cause welding the problem not exclusively occurring to leak.
In preferred embodiments, be provided with between described quartzy pipe cap 2 and described first O-ring seal 4 and stagnantly move unit 9 and removable, be convenient to place quartzy pipe cap 2, when ensureing to vacuumize, quartz pipe cap 2 does not depart from high temperature welded tube district simultaneously.
In preferred embodiments, the described stagnant unit 9 that moves for quartz pushrod or quartzy cutting ferrule 5, but is not limited to this, can also carry out other as required and select.
In preferred embodiments, described cutting ferrule 5 is communicated with described vacuum machine 8 by valve tube 7, and described cutting ferrule 5 is provided with the second O-ring seal 6 with described valve tube 7 junction.
