Abstract
The invention relates to a self-locking device for a two chamber vacuum furnace. The self-locking device comprises a furnace door arranged between a high temperature area and a cooling area, a temperature sensor arranged in the high temperature area, a valve for opening or closing the furnace door under the control of the temperature sensor, a furnace door bolt arranged on the furnace door and positioned in the cooling area, and a positioning piece arranged on the furnace door, positioned in the high temperature area and capable of matching the valve, wherein the valve has a first working state and a second working state; when the valve is positioned in the first working state, the temperature of the high temperature area is higher or equal to a temperature parameter set by the temperature sensor, and the valve is closed; and when the valve is positioned in the second working state, the temperature of the high temperature area is lower than the temperature parameter set by the temperature sensor, and the valve is opened. In the self-locking device for the two chamber vacuum furnace, the temperature sensor arranged in the high temperature area is adopted to control the matching of the valve and the positioning piece, the self-locking of the furnace door is realized, accidents are prevented, and the work efficiency is improved.

Technical field
the present invention relates to a kind of self-locking device of two chamber vacuum furnace.
Background technology
at present, two chamber vacuum furnace generally comprises elevating mechanism, vacuum system, cooling system, electric-control system of fire door, grate, bell, bell and workpiece between body of heater, two chamber etc., wherein the temperature of two Room differs greatly, when workpiece after Overheating Treatment, if directly the workpiece after heat treatment is moved to another operating room, because temperature is higher, bring potential safety hazard to operating personnel, easily have an accident, if after waiting workpiece fully cooling, move to again another operating room, reduced like this operating efficiency.
Summary of the invention
technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of self-locking device of improved two chamber vacuum furnace is provided.
for solving above technical problem, the present invention takes following technical scheme:
a kind of self-locking device of two chamber vacuum furnace, it comprises the fire door be arranged between high-temperature region and cooling zone, and self-locking device also comprises the temperature inductor be arranged in high-temperature region, the valve of controlling oven door opening or closing by temperature inductor, the keeper that is arranged on the fire door bolt on fire door and in cooling zone and is arranged on fire door and can matches with valve in high-temperature region, wherein valve has the first duty and the second duty, when locating the first duty, the temperature of high-temperature region is greater than or equal to temperature inductor established temperature parameter, this valve is in closing state, when locating the second duty, the temperature of high-temperature region is lower than temperature inductor established temperature parameter, and this valve is in open mode.
preferably, the set temperature parameter of temperature inductor is 80 ℃.
preferably, valve rotates be arranged on the interlayer between high-temperature region and cooling zone and can with fire door on the keeper tabling.
due to the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
the self-locking device of vacuum drying oven of the present invention adopts coordinating of the temperature inductor by-pass valve control that is arranged on and keeper the high-temperature region in, has realized the self-locking of fire door, and trouble-saving generation is increased work efficiency simultaneously, and simple in structure, and enforcement facilitates.
The accompanying drawing explanation
below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described in detail:
