  • Patent number: 11428351
    Abstract: A lock device for a coupling part of a piping or valve of a raw-material container or the like, capable of preventing looseness and erroneous operation of a coupling, and having favorable stability because the device is fixed as a force is applied to a direction of additionally fastening the coupling. The lock device is provided for achieving prevention of looseness of a coupling part (4) formed of a screwed member (20) and a screwing member (21) side, and includes a clamp member (42) for additional fastening attached to the screwed member side, a clamp member (41) for positioning and fixing attached to the screwing member side, and a screw member (43) for fastening the clamp members. The clamp members are fastened with the screw member (43), thereby being fixed to the coupling part while a force is applied to a direction of additionally fastening the screwing member side.

  • Patent number: 11428359
    Abstract: A female fluid connection element (5), configured to be coupled with a male element (4). A female body (21), which has an insertion channel (27) of the male element (4); locking elements (31) movable between positions; and a maneuvering ring (71) with an inner sleeve (75) for driving the locking element (31) to their proximal position. In order to have a small bulk and to offer particularly easy and reliable locking and unlocking, the female element (5) has a return plunger (33), returning the locking elements (31) toward their distal position, and a resilient member (43), exerting a return force to bring the return plunger (33) back toward a forward position. By being moved toward its withdrawn position, the maneuvering ring (71) drives the return plunger (33) toward a rear position, such that it does not exert a return force on the locking elements (31).

  • Patent number: 8783730
    Abstract: A flange assembly for a watertight coupling of smooth surface pipe includes a triple metal ring provided for anchoring and retention and having three unitary rings which are identical and form substantially an entirety of a circumference and a sheet on which the unitary rings are solidly joined and which constitutes a base of the triple ring. Each of the unitary rings is provided throughout an entirety of its inner edge with folds forming in their outer most part a succession of vertices. The unitary rings are configured to rest on a smooth outer surface of pipes and the vertices are driven into the smooth outer surface to prevent an axial displacement allowing an application of the triple ring, and to distribute a penetrating action so as to decrease a possibility of tearing and damage of the smooth outer surface of the pipes.

  • Patent number: 8746751
    Abstract: A threaded adapter is part of a quick-to-connect and quick-to-disconnect flexible hose coupling system. The adapter may provide a low-profile securement and seal between the port and the stem portion of the quick connect coupling. The adapter in combination with the fluid valve block orifice provides a seal that is further down in the valve block than the location of seals provided by other fluid couplings. Without relying on wrenching flats, the adapter also provides effective access to the hoses for repair and therefore is a cost saving device. The adapter may be a safe, reliable, easy to connect and disconnect component in a hydraulic system and is adaptable to accommodate any coupling including those in high and low pressure fluid and other systems.
