Abstract:
PROBLEM TO BE SOLVED: To provide a means capable of ensuring air-tightness by preventing local plastic deformation of a pin nose during compression load being applied when a shoulder angle θ is 0° or more.SOLUTION: A box side lip length L as a pipe axial distance from a pin nose top end corresponding point P of a box member 1 to a load surface 18b of a screw thread 50 referable to lip that is a female screw thread most proximate to the pin nose top end corresponding point P is set 300 times or more of an insertion surface gap δ between an insertion surface 19b of the female screw thread on a position to which the female screw thread retreats two rounds or more from the screw thread 50 referable to lip and an insertion surface 19a of a male screw thread facing the insertion surface 19b upon fastening, that is, L≥300×δ.
Abstract:
Exemplary embodiments relate to a fastener (200) suitable for industrial tasks. Some embodiments include a sealing surface (208) sized so that an outer surface of a sealing ring (202) is located at approximately the same diameter as the fastener head, thus reducing ingress risk for foreign contaminants. Further embodiments provide a centering pilot (210) to improve sealing consistency and quality. Some embodiments provide an angled flange (206) on the fastener head to lift tightening tools away from the surface to which the fastener is being applied, and to shed liquids readily. The portion of the head that receives the tightening tools may be relatively small (approximately the same diameter as the fastener's threaded shaft) to reduce the risk of over-torqueing. A bearing surface (212) of the fastener (200) may be located below the sealing ring (towards the threaded shaft (214)) to prevent the fastener from marring the unsealed surface to which the fastener is being applied.
Abstract:
A rapid connect coupler including a housing, a probe (215) configured to translate within the housing, a handle (130A) assembly configured to cause the probe (215) to translate within the housing body, a stop assembly configured to selectively arrest the translation of the probe, the stop assembly including a pawl (520) configured to occupy both an active position and an inactive position, wherein the inactive position arrests the translation of the probe (215); a catch (510) fixed to the housing and configured to hold the probe (215) in the inactive position; a lever (501) configured to engage the pawl (520); a spring (502) fixed to both the housing and the lever (501) and configured to bias the pawl (520) to the inactive position via the lever (501); and a cam (530) configured to disengage the pawl (520) from the catch (510) and cause the pawl (520) to occupy the active position.
Abstract:
Ein Bördeldichtring (13) dient zur Abdichtung einer Rohrverbindung, wobei der Bördeldichtring (13) aus einem Material mit einem metallischen Anteil hergestellt ist und der metallische Anteil im Wesentlichen homogen in dem Bördeldichtring (13) verteilt ist. Dadurch kann der Bördeldichtring bei einer Vor- richtung (1) zur Erfassung von Bestandteilen eines Bördeldichtringes (13) in einer Rohrleitungsanlage eingesetzt werden, die mehrere Rohre (2), umfasst, wobei mindestens zwei Rohre (2) an einem Flansch (12) über einen Bördeldichtring (13) abgedichtet aneinander gehalten sind. Über einen Metalldetektor (4) und eine in Förderrichtung hinter dem Metalldetektor (4) angeordnete Schleuse (8) zum Entfernen einer metallhaltigen Substanz aus der Rohrleitung, kann dann der Bördeldichtring (13) detektiert werden, so dass bei Ablösen von Bestandteilen des Bördeldichtringes (13) eine Erfassung an dem Metalldetektor (4) und ein Ausschleusen ander Schleuse (8) durchführbar ist.
