Description
Technical field
The present invention relates to bactericidal unit field, particularly, relate to a kind of steam autoclave with hermetically-sealed construction.
Background technology
Heat sterilization is a kind of conventional sterilizing means, because high temperature has obvious lethal effect to antibacterial.High temperature makes thalline degeneration and solidifies, and enzyme loses activity, thus makes bacterial death.Heat sterilization is the most reliable, and the sterilizing methods generally applied the most ripe is usually by moist heat sterilization and dry heat sterilization two kinds of methods.
At the same temperature, damp and hot bactericidal effect is better than xeothermic, there is following reason: the temperature needed for protein coagulating is relevant with its water content, water content is larger, solidify temperature required lower, sterile body protein Absorbable rod moisture during moist heat sterilization, thus more easily solidifies than in the heated dry air of same temperature; In moist heat sterilization process, steam releases a large amount of latent heat, improves temperature further, and at the same temperature, the time needed for moist heat sterilization is shorter than dry heat sterilization; The penetration power of hot and humid gas is stronger than dry gas, therefore damp and hot than xeothermic produce effects good, high steam can kill all microorganisms, even comprises the spore of antibacterial, the resistant to elevated temperatures individuality such as the spore of fungus, the vapor (steam) temperature of sterilizing raises with the increase of steam pressure, by increasing steam pressure, sterilization time is considerably reduced, therefore, it is that one is the most effective, most popular sterilizing methods.
Moist hear heat test adopts steam autoclave to carry out sterilizing, poorly sealed between the cylindrical shell of existing steam autoclave and cover, causes sterilization time to lengthen.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of steam autoclave with hermetically-sealed construction, to overcome problem poorly sealed between the cylindrical shell of existing steam autoclave and cover.
The present invention's adopted technical scheme that solves the problem is: the steam autoclave with hermetically-sealed construction, comprise cylindrical shell, the cover coordinated with cylindrical shell, cylindrical shell is provided with shift knob, jack, cover is provided with air nozzle, Pressure gauge, the outer wall that cylindrical shell coordinates with cover is provided with annular nib, annular nib, the outer wall of cover is provided with the fixed block that at least 4 groups cooperatively interact, fixed block inside is provided with tapped through hole, the leading screw being equipped with nut is located in tapped through hole, the upper end of described annular nib is provided with annular groove I, the annular groove II coordinated with annular groove I is provided with inside cover, rubber blanket is fastened on annular groove I, between annular groove II.Between the cylindrical shell of existing steam autoclave and cover, hermetically-sealed construction is not set, thus poorly sealed, in sterilization process, steam leaks outside, sterilization time is caused to lengthen, the present invention is by being provided with annular groove I in the upper end of annular nib, the annular groove II coordinated with annular groove I is provided with inside cover, rubber blanket is fastened on annular groove I, between annular groove II, add the sealing between cylindrical shell and cover, avoid steam in sterilization process to leak outside the poorly sealed problem caused, use procedure of the present invention: add appropriate water in cylindrical shell, after the article of required sterilizing are put into cylindrical shell, rubber blanket on annular groove I pads, annular groove II is coordinated being closed by cover with rubber blanket, again leading screw being located in tapped through hole and tightening gradually, close air nozzle, jack is energized, opening switch button, start sterilizing, after sterilizing completes, closing switch button, powered-down, open air nozzle, when manometric reading is zero, open cover, article after sterilizing are moved on to sterilizing room, sterilizing terminates.
Further, the outer wall of rubber blanket is provided with annular protrusion.Annular protrusion and external diameter are greater than the external diameter of rubber blanket, can improve the stability of rubber blanket at annular groove I, annular groove II, avoid rubber blanket to occur the problem of skidding.
Further, cover upper surface is provided with hand-held rod.The open and close of cover are convenient in the setting of hand-held rod, improve the convenience of operation.
Further, the lower end sidewall of cylindrical shell is provided with outlet pipe.The setting of outlet pipe is convenient to sterilization water directly be discharged from outlet pipe after sterilizing terminates, and improves the convenience of operation.
Further, annular nib and cylindrical shell are structure as a whole.Integrative-structure improves the structural stability of annular nib.
To sum up, the invention has the beneficial effects as follows:
1, the present invention is by being provided with annular groove I in the upper end of annular nib, the annular groove II coordinated with annular groove I is provided with inside cover, rubber blanket is fastened between annular groove I, annular groove II, add the sealing between cylindrical shell and cover, avoid steam in sterilization process and to leak outside the poorly sealed problem caused.
2, the present invention by arranging annular protrusion on the outer wall of rubber blanket, can improve the stability of rubber blanket at annular groove I, annular groove II, avoids rubber blanket to occur the problem of skidding.
