Embodiment Construction

[0022] First refer to Figure 1 to Figure 3 , a sanitary clamp, the standard C-clamp or three-piece clamp 10 of the prior art, is presented as a standard for handling the ends of connected pipes of equipment coupled to sanitary conduits, for example during Devices, i.e. the process is used in dairy products, another edible product such as juice, sauce or soup, or in medicinal products for human or veterinary use, or cosmetic, beauty-related or dermatological cream or liquid. Typically, many of these sanitary clamps are used in any commercial processing operation of this type.

[0023]The hygienic clamp 10 of this example has a first half-ring 12 and a second half-ring 15 coupled at the proximal end to a clamping hinge member 16 with open jaws Members 18 protrude from the proximal end of half-ring 12 as radial fingers, with bolt slots 19 extending along the jaw members 18 . The threaded closure member 20 , here a swing bolt 26 or eye bolt 26 , has a head or eye that is captu...

Abstract

A sanitary clamp (110) with facing ring halves employs one or more threaded closure devices configured to avoid having any threads exposed to the ambient. A bolt member (130) may have a stepped shaft with a first smooth shaft portion (126) and a male- threaded tip portion (132). The latter may be the same or a smaller diameter. An associated nut member (128) has a blind bore that extends from a first end of the nut, with a first smooth wall portion (134) and a second female threaded bore portion (136). The second female threaded portion may have the same bore diameter, or the bore can have a stepped interior diameter with the second female threaded bore portion having a diameter smaller than the first smooth wall portion. A seal member or gland (138) within the smooth wall bore portion closes off a space defined between said the tip portion (132) of the bolt member and the female- threaded bore portion (136). Once installed, all threaded surfaces of the bolt member and the nut member that are concealed from the ambient.

Description

Background technique [0001] The present invention relates to a device for sanitary clamps for joining together two flanged pipes or pipes in such a way that the junction of the two flanged ends is sealed and the cleaning fluid is allowed to pass through Come clean the tube and associated equipment in place. The present invention more particularly relates to a sanitary clamp employing a threaded closure such as a bolt or eyebolt and associated wing nut or hex nut to secure the clamp to a flanged pipe On the end, and when screwed onto the clamp, the closure has no exposed threads that could harbor bacteria or other contaminants and be difficult to clean. [0002] There are many styles of hygienic clamps, by names such as the common tri-clamp, C-clamp, tri-clover, ferrule, cleaning ferrule, cleaning clip Clamps, Clean Clamp Clamp Ferrules and Clean Clamp Fittings, etc. [0003] Over the past decade, sanitary pipes and sanitary containers have been subject to extensive scrutiny...
