Abstract: A safety isolation valve module includes a conduit having a service port, an inlet, an outlet, and ball valves separating each of the inlet and the outlet from the conduit. The ball valves may be manually manipulating to open or close flow and can be used to isolate the service port from either or both sides of the refrigerant systems. When servicing the service port or other components of the refrigerant system, the valves may be shut to enable servicing of portions of the system without risking injury or losing significant amounts of refrigerant to the atmosphere.

Abstract: Disclosed is an armature for receiving a sensor for measuring a medium in a container. The armature includes a hollow cylindrical housing designed to connect the armature to the container at least sectionally in the container. The housing includes first and second openings through which medium flows in or out; a service chamber formed in the interior of the housing between the first and second openings; a rotationally movable closing element in the housing, which, in a first position, opens the first and second openings to the medium and, in a second position, blocks a flow through the first and second openings; a sensor holder; and the sensor arranged on or in the sensor holder. The sensor holder is designed such that the sensitive element is arranged in the service chamber in the measuring/service position.

Abstract: A water sprayer long tube and water pipe connector, having formed along a bottom section internal threads that are followed in respective order from its water inlet end by a first polytetrafluoroethylene water sealing ring, a ball valve, and a second polytetrafluoroethylene water sealing ring for coupling the two components. The opening of the water outlet end is of a smaller inner diameter than that of the opening at the water inlet end and a water sealing ring is ensconced along the inner diameter edge of the water outlet end. A flange formed at the bottom end of the long tube in the water inlet end of the connector is secured and constrained inside the connector, with the constraining of the long tube flange of the water sprayer enabling it to become assembled with the connector into a single structural entity that cannot be disconnected.
