Abstract

The invention discloses an NA (Numerical Aperture) connector type sight mirror, comprising a sight mirror base, a sight mirror glass, a glass gland and a sight mirror gland, wherein the glass gland is a cylindrical ring part, the glass gland comprises a buckling section having the upper edge extending inward and a sealing section having the lower edge extending outward, the glass gland covers the sight mirror glass via the buckling section, and the sealing section is fitted with a sealing washer; the sight mirror gland is a disc-type ring part and comprises a transition section having the inner edge extending downward, the sight mirror gland covers the sight mirror base, the transition section is in tight fit with the sealing section, and the glass gland is thus fixed. The NA connector type sight mirror has the advantage of no visual dead angle without sintered glass, is convenient to clean on line, has good sanitation property in the presence of the internal sealing washer, greatly reduces the manufacturing and equipment input cost, and thus has wide economical benefits and application prospect.

Description

technical field [0001] The invention relates to an NA interface type sight glass. Background technique [0002] In the pharmaceutical, food and personal care products industries, it is often necessary to set a viewing window on the configuration tank to observe the state of the internal materials. Nowadays, the main forms of sight glass are flange connection type, threaded by any type and NA interface type Among them, the flange connection type is widely used, but because it is sealed by a flat gasket, there is a certain hygienic dead angle, and the volume is large, so it is difficult to apply to the miniaturized equipment of the pharmaceutical factory. The threaded sight glass has the characteristics of compact structure. Because it is sealed by an O-ring, it is also better than the flange type sight glass. However, due to its own structural characteristics, it needs a larger height to be installed, which also causes its H The / D value (wherein, the H value represents the ...
