State and be bolted connection between visor base and the visor gland.
In the present invention, the visor base is preferably flange base, and the cross section of the visor base is preferably recessed
Shape.
In the present invention, preferably located at the center of the visor base, the diameter of the mirror mouth is preferable for the mirror mouth
Ground constantly increases from top to bottom until equal with the base diameter of the visor base.
In the present invention, the seal washer is seal washer commonly used in the art, generally standard TC sealing ring, compared with
It is clip sealing ring goodly, the clip sealing ring meets ASME BPE standards commonly used in the art, to guarantee and pipeline
Inward flange ensure concordantly without dead angle.
In the present invention, the diameter of the seal washer is preferably greater than the endoscopy glass, to ensure the visor base
Described in seal washer installation bit width.
In the present invention, the material of the endoscopy glass is preferably tempering Pyrex, to ensure to tolerate conventional sterilant temperature
Degree.
In the present invention, the upper limb of the seal section is preferably an inclined-plane, the lower edge of the seal section and the sealing gasket
Circle is preferably accordingly provided with groove.
In the present invention, the changeover portion preferably is provided with an inclined-plane corresponding to the seal section, with tight with the seal section
Closely connected conjunction.
In the present invention, the without individual tolerance value grade for withholding the flatness of contact portion between section and the endoscopy glass
Preferably H levels or more, are defined by the requirement of CNS GB/T1184-1996.
In the present invention, the without individual tolerance value grade of the axiality between the glass gland and the endoscopy glass is preferably
For H levels or more, it is defined by the requirement of CNS GB/T1184-1996.
On the basis of common sense in the field is met, above-mentioned each optimum condition, can combination in any, obtain final product each preferable reality of the present invention
Example.
The present invention positive effect be：The present invention is by NA interface types flange and endoscopy glass and glass gland
Combination, solves the shortcomings of traditional visor, realizes original NA interface types visor no visual dead angle without the need for sintered glass
Advantage, and facilitate on-line cleaning, built-in seal washer also has more preferable sanitation performance than conventional flat shim and O-ring, greatly
Visor manufacture and equipment investment cost is reduced greatly, with wide economic benefit and application prospect.
