摘要:
The present invention relates to an improved pressure adjusting device for controlling the flow rate of liquid gases, which comprises a body (1) consisting of a top half shell (3) and a bottom half shell (2), coupled to one another through the interposition of a resilient membrane (4) which defines a gas pressure control chamber (6) and a gas pressure reducing and delivery chamber (5), communicating with a gas delivery outlet. The bottom half shell (2) defines a cylindrical end piece (7) which can be coupled to the valve (8) of the gas pressure vessel (9). The main feature of the invention is that there are provided quick coupling means (10), operating between the end piece (7) and the valve (8), which are adapted to operatively engage with the operating knob (13) of the valve means of the adjusting device for preventing the adjusting device from improperly engaging with or disengaging from the gas pressure vessel (9) as the mentioned valve means are in their opening position.
摘要:
The fluid coupling comprises first and second connectors (20, 30) each configured for attachment (at respective ends 21 and 31) to respective fluid conduits, for example hydraulic hoses. Each connector (20, 30) has a cylindrical body (3,3') configured to rotate about the longitudinal axis A having a bore or lumen (22,32) for fluid flow therethrough in a predetermined orientation as indicated by arrows D. Registration of the respective lumens (22,32) at ends (23,33) of the connectors permits fluid to flow between the connectors (20,30) at maximum rate when lumens (22,32) are aligned with apertures (24 ',34)', fluid to be stopped when lumens butt against shutters (24, 34), and fluid to flow at intermediate rate when lumens are registered in intermediate positions.
摘要:
A security and safety latch system for fluid couplings (10) particularly for fluid couplings utilizing rotatable valves (68) wherein connection and disconnection of the coupling parts (12, 14) is by relative rotation of the parts and the valves (68) are rotated between open and closed positions by exterior manually operated handles (86). The coupling parts (12, 14) and the valve handles (86) are provided with interfering surfaces (119) which prevent the parts from being relatively rotated and disconnected until both coupling valves (68) are closed. Further, the valve handles (86) are provided with security latches (100) which permit the handles (86) to be locked in the closed position, and prevent the valve handles (86) from being locked in the valve open position.

摘要:
Système de verrouillage de sécurité et de sûreté pour raccords de fluide (10), notamment pour des raccords de fluide utilisant des robinets tournants (68), dans lequel le branchement et le débranchement des parties de raccordement (12, 14) s'effectuent par rotation relative desdites parties, et les robinets (68) sont mis en rotation entre des positions ouvertes et fermées par des manettes extérieures (86) fonctionnant manuellement. Les parties de raccordement (12, 14) ainsi que les manettes (86) des robinets sont dotées de surfaces de bloquage (119) empêchant les parties de tourner l'une par rapport à l'autre et de se déconnecter jusqu'à ce que les deux robinets de raccordement (68) soient fermés. Les manettes (86) des robinets sont également dotées de crans de sûreté (100) permettant le verrouillage des manettes (86) en position fermée, et empêchant le verrouillage desdites manettes (86) des robinets dans leur position ouverte.
