Long strict conformance, heat input change caused by arc length change and wire feed change are prevented, while disclosure satisfy that high temperature and high pressure steam valve
The manufacture demand in door sealing face, also the Overhaul site of equipment can be installed directly to producing rejected region progress built-up welding and repairing
It is multiple；The utility model according to actual process demand, can flexibly switch the species and speed of wire feed at the scene, meet in height
The built-up welding of all positon dell and compound increasing material manufacturing of warm high pressure steam valve inner sealing surface；The utility model scene does not have to change
Wire tray, the species and quantity of TIG welding guns welding process filling metal can be switched at any time.
Heat treatment system is mainly used in the front and rear preheating and heat treatment of valve sealing face welding, its mode of heating (it is interior and
Outside), heating power supply power (30~80KW), coil dimension, the type of cooling (water cooling is air-cooled), Technology for Heating Processing etc. are also according to work
The pattern of part selects.When needing heat treatment, frock is fixed on bonnet first with valve ending cover bolt, then by heating coil
It is fixed in L-type mobile dish, connects the water-cooled cable of heating power supply and induction coil, before welding or reparation, induction coil leads to
The bonnet flange mouth that lifting platform frock is first moved to valve body is crossed, then enters back into valve cavity the interior hole position until sealing surface
Put, be heat-treated for outer wall, it is mainly by control system, 60KW intermediate frequency induction heating power supplies, flexible air-cooled external heat cable group
Into it, which heats cable, can be directly wound in irregular valve outer wall, and it is always at the end of whole welding is preheating to since valve
It is in running order, formed together " hot dam " in valve outer wall, prevent from excessively radiating, to ensure sealing surface heating effect, inwall
Work is started simultaneously at outer wall heat treatment, after preheating temperature is constant, only exits interior heating coil, outer wall heat treatment continues constant temperature
Degree, to ensure the interlayer temperature in welding or repair process, after completing welding or repairing, interior heating coil enters, with external heat
Coil proceeds by post weld heat treatment with identical heating rate, constant temperature time, rate of temperature fall, until whole heat treatment process is complete
Portion completes, and in actual heating process China and foreign countries, the flexible air-cooled coil cable of heating power supply is wrapped in the outside in valve welding face, its
Work has five stages, wherein inside heating when withdrawing from its heating-up temperature ensure during welding solder side temperature not less than 300 DEG C~
350 DEG C, the first stage is the warm-up phase of welded seam area, and heating induction coil drives through lifting platform frock and arrives valve body in the stage
Internal repair face position, external heat works simultaneously in the stage, be heated position according to default heating rate heat up it is pre-
Heat, second stage are preheating temperature constant temperature, in order to ensure that welding or the inside and outside wall temperature at reparation position are consistent, the
In three stages, interior heating induction coil is driven by lifting platform frock after preheating temperature is constant extracts out inside valve cavity, now outer
The work of heating and continuous second stage, ensure that welding or repair process temperature are not less than 300 DEG C, until welding or repair knot
Beam, heated simultaneously inside and outside the four to five stage, the heat treatment cycle curve heating and cooling to work according to setting so can be according to existing
