Abstract
The utility model discloses an improved pit type vacuum annealing furnace, which comprises a furnace body and a furnace cover, wherein a sealing ring is arranged at a joint of the furnace body and the furnace cover. The improved pit type vacuum annealing furnace is characterized in that the sealing ring comprises an inner ring and an outer ring; the outer ring of the sealing ring is a heat-resistant rubber sealing ring; the inner ring of the sealing ring is asbestos packing; and a pressure safety protection device is arranged on the furnace cover. According to the annealing furnace structure, the vacuum degree in the furnace body can be guaranteed, and the air tightness and stability are greatly improved compared with the prior art; and because the pressure safety protection device is arranged on the furnace cover, the annealing furnace has high safety performance.
Description
Technical field
The utility model relates to the lehre technical field, is specifically related to a kind of new-type well vacuum lehre that guarantees stopping property in the body of heater.
Background technology
In type material research and production process, how short annealing is a vital link that improves material property.In order to make metal objects have needed mechanical property, physicals and chemical property, except the various technologies of choose reasonable, annealing process is requisite often.Lehre is to carry out the common equipment that metallic substance is handled, and when heat-treating, lehre need remain on elevated-temperature seal under the vacuum environment, need cool fast sometimes.Use the glass fibre cotton sealing between existing bell and the body of heater; Owing to the characteristic reason of body of heater and bell itself, resistance to air loss is relatively poor when causing the use glass fibre cotton, thereby causes the poor sealing of bell and body of heater; Make and sneak into oxygen in the body of heater, therefore be not suitable for the vacuum annealing furnace operation.
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of new solution.
The utility model content
The technical problem that the utility model will solve is: the deficiency that is directed to prior art; A kind of improved well vacuum lehre is provided; This improved well vacuum annealing furnace structure can guarantee the intravital vacuum tightness of stove; Resistance to air loss and stability also are provided with the pressure security protector on bell, make this lehre also have better safety performance.
For reaching the foregoing invention purpose, the technical scheme that the utility model adopted is: a kind of improved well vacuum lehre is provided, comprises body of heater and bell; The joint of said body of heater and bell is provided with sealing-ring; It is characterized in that: said sealing-ring comprises Internal and external cycle; Said sealing-ring outer ring is a heat-resistant rubber seal ring; Said sealing-ring inner ring is an asbestos packing; Said bell is provided with the pressure security protector.
Further, said body of heater skeleton is formed by section bar and steel plate Combination Welding.
Further, on the said pressure security protector superpressure combined aural and visual alarm is installed also.
In sum, the improved well vacuum lehre that the utility model provided has following advantage compared to prior art:
1, this lehre can guarantee the intravital vacuum tightness of stove, and resistance to air loss is greatly improved than prior art with stability.
2, also owing on bell, also be provided with the pressure security protector, make this lehre also have better safety performance.
Description of drawings
Fig. 1 is the sectional view of improved well vacuum lehre.
Wherein, 1, body of heater; 2, superpressure combined aural and visual alarm; 3, bell; 4, sealing-ring outer ring; 5, sealing-ring inner ring.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to be described in detail:
As shown in the figure, this improved well vacuum lehre comprises body of heater 1 and bell 3; The joint of said body of heater 1 and bell 3 is provided with sealing-ring; It is characterized in that: said sealing-ring comprises Internal and external cycle; Said sealing-ring outer ring 4 is a heat-resistant rubber seal ring; Said sealing-ring inner ring 5 is an asbestos packing; Said bell 3 is provided with the pressure security protector; Said body of heater 1 skeleton is formed by section bar and steel plate Combination Welding; On the said pressure security protector superpressure combined aural and visual alarm 2 is installed also.
Said sealing-ring is inside and outside two circles; Said sealing-ring inner ring 5 is an asbestos packing, and sealing-ring outer ring 4 is a heat-resistant rubber seal ring, and sealing-ring inner ring 5 blocks the part heat like this; Reduce the aging of sealing-ring outer ring 4 effectively, guaranteed the resistance to air loss and the stability of lehre; And in order to guarantee the security of lehre, also the pressure security protector is provided with the superpressure combined aural and visual alarm, has increased its security especially.
In sum; The improved well vacuum lehre that utilizes the utility model to provide; Its structure can guarantee the intravital vacuum tightness of stove; Resistance to air loss is greatly improved than prior art with stability, owing on bell, also be provided with the pressure security protector, makes this lehre also have better safety performance.
Though describe in detail in conjunction with the embodiment of accompanying drawing, should not be construed as qualification to the protection domain of this patent to the utility model.In the described scope of claims, various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
