Description

Water welder

Technical field

The utility model relates to welding set, a kind of water welder that adopts the hydrogen-oxygen welding of saying so exactly, and this water welder is stable, reliable, the gas producing efficiency height.

Background technology

Water welder is to be the abbreviation of the oxyhydrogen flame welding robot of raw material with water, utilize water under basic catalyst (as sodium hydroxid or potassium hydroxide) effect, the logical direct current at the electrolyzer two ends, water generation electrochemical reaction is generated hydrogen and oxygen, with hydrogen as fuel, comburant oxygen forms oxyhydrogen flame through the igniting of oxyhydrogen flame rifle again through safety valve and spark arrester, and workpiece is welded.It mainly is made up of electrolyzer, electrolysis power, safety valve and spark arrester, flame regulating tank, oxyhydrogen flame rifle.

Water welder has plurality of advantages, as: combustion gas is produced as required, does not store safe ready; Raw material is simple, only needs water power, and i.e. usefulness is promptly produced in start, and economical and practical, volume is little, and mobility is good; Products of combustion only is water, and is free from environmental pollution; Flame is concentrated, and is suitable for accurate flame machining; Oxyhydrogen flame is carbon-free flame, and the workpiece welding is fastening, carbon-free crisp phenomenon.Various industries such as product polishing, synthetic glass flame polish, jewel welding, the welding of motor enameled wire, artificial tooth welding and tooth die repair benefit, mirror holder welding, optical fiber welding, small scale flame spraying, the silica tube that therefore is widely used in the acryl artwork seals, air-conditioning brazing welding, accumulator cell lead pole plate group welds, the oxygen that adds high pressure can cut all thickness steel plate, quartz glass bar die cast, pharmaceutical factory's aqueous injection ampoule wire drawing are sealed, workpiece quenching.

For example patent application 00213560.4 has proposed a kind of structure of water welder, this water welder, it is made up of serially connected electrolytic jar, gas drier, multiple fireproof tempering device, dither dc electrolysis power supply and Controlling System etc., sealing tubular type sleeve structure in its electrolytic cell adopts, gas drier adopts the cooling of gas adiabatic expansion, constitute by expansion-head, drainer, though this structure can suitably improve the efficient of aerogenesis, yet the raising of efficient is also little, and lack enough safety assurances, popularization is difficult to be applied.

Therefore, patent application 200820032225.5 has proposed a kind of water welder of horizontal type, this water welder is horizontally set at electrolyzer the bottom of water welder, simultaneously by spark arrester is set, carry out safety assurance, and radiator element is set on pipeline, improved the radiating efficiency of water electrolytic gas, but also there are a lot of problems in itself, a radiator element is arranged on the pipeline, take the internal space of too many water welder, influence radiating efficiency on the contrary, single electrolyzer is still adopted in two electrolysis, and electrolytic efficiency is difficult to improve, to such an extent as to electrolytic gas can not reach enough welding requirements, therefore, for some Application Areas, must adopt powerful water welder, such as the water welder of power more than 1000W, this will certainly cause the waste of the energy.
