A method of fabricating a fluid component body includes forming a monolithic fluid component body including a valve segment having an annular upper perimeter wall portion defining a valve cavity and a lower base portion defining first and second flow ports, and a conduit segment extending from one of the first and second flow ports and including a conduit end portion defining a tubular portion extending in a first direction and spaced apart from a remainder of the fluid component body. The conduit end portion is bent from the first direct to a second direction.

Fluid component body and method of making same

A flow sensing device includes a first body member defining an inlet port, an upstream sensor port, and a first connecting port; a second body member defining an outlet port, a downstream sensor port, and a second connecting port; a flow restricting element defining a flow restricting passage and including a first end connection coupled to the first connecting port and a second end connection coupled to the second connecting port, such that the flow restricting passage is disposed between the inlet port and the outlet port, and between the upstream sensor port and the downstream sensor port; a first fluid sensor assembled with the upstream sensor port; and a second fluid sensor assembled with the downstream sensor port.

Fluid monitoring module arrangements

A fluid monitoring module includes a flow sensing device and a controller disposed in an enclosure. The flow sensing device includes a body including an inlet port, an outlet port, an upstream sensor port, a downstream sensor port, and a flow passage disposed between the inlet port and the outlet port, and between the upstream sensor port and the downstream sensor port. A first fluid sensor is assembled with the upstream sensor port, and a second fluid sensor is assembled with the downstream sensor port. The controller is in circuit communication with the first and second fluid sensors for receiving at least one of pressure indicating signals and temperature indicating signals from each of the first and second fluid sensors, and for measuring fluid data based on the received signals.

Mechanically attached connections for conduits may include a conduit gripping member and first and second connection members. The first and second connection members may be, for example, a nut member and a body member where the connection members cause axial movement of the conduit gripping member to grip and seal the conduit when the assembly is pulled-up. The mechanically attached connection may include a sensing function for detecting or sensing a condition or characteristic of at least one of the following: the mechanically attached connection, one or more of the connection members, the fluid contained by the mechanically attached connection, or a combination thereof. The sensing function may be, for example, a sensor that is integrated with at least one of the nut member and the body member.

Conduit connection with sensing function

An electrically controlled fluid control valve comprises an electrical position controller governed by a signal proportional to the position of a movable element of the valve to regulate current to a shape memory alloy (SMA) valve actuator to position the movable element to a desired position. The control valve may also include a temperature controller governed by a signal provided by a temperature-sensing element in proximity to the valve actuator to activate a cooling device for reducing the surrounding temperature. A digital selector switch may be used for generating a digital code of a selected heating rate which may govern the electrical controller to regulate current to the SMA drive element. The electrical controller may also be governed by both position measurement and a temperature signals to regulate current to the SMA valve actuator and to control the cooling device to position the movable element to a desired position.

Shape memory alloy actuated fluid control valve

A fluid control valve having a shaped memory alloy (SMA) driven actuator is disclosed. The SMA driven actuator includes a first frame section coupled to a valve body and fixed in relation thereto, a second frame section coupled to a movable element of the valve body and movable in relation to the valve body, and a multiplicity of SMA wire sections coupling the first and second frame sections for moving the movable element from a biased first position to a second position when heated. An electrical controller controls the heating of the SMA wire sections by regulating current therethrough, preferably using pulse width modulation techniques. The electrical controller may be governed by a position measurement signal proportional to the position of the movable element to regulate current to the SMA drive element to position the movable element to a desired position. The position measuring signal may be provided from a position measuring element integral to the valve actuator. The valve actuator may also include a temperature controller governed by an electrical temperature signal provided by a temperature-sensing device in proximity to the SMA drive element to activate a cooling device for reducing the temperature surrounding the SMA drive element when activated. A digital selector switch may be used for generating a digital code of a selected heating rate which may govern the electrical controller to regulate current to the SMA drive element. The electrical controller may also be governed by both a position measurement and a temperature signal to regulate current to the SMA drive element and to control the cooling device to position the movable element to a desired position. The actuator may include at least one bobbin that is wound with a multiplicity of wire windings. A conductive material may be applied to the surface of grooved sections of the bobbin onto which the SMA wire windings are wound. Alternatively, the SMA wire may be coated with a conductive material and then wound about the bobbin and thereafter, the conductive material may be removed from the surface of the SMA wire not in contact with the bobbin.

An orbital welding apparatus includes a first housing defining a weld head assembly and a circular rotor disposed therein for rotation about a first axis. A welding electrode is carried by the rotor for welding. A second housing separate from the first housing forms a power transmission and has a second drive shaft extending therefrom. A flexible drive shaft connects the first drive shaft and the second drive shaft to conduct rotary drive forces from the first drive shaft to the second drive shaft while permitting the relative orientations of the first and second housings to be freely adjustable. A third and independent housing carries an electric drive motor and forms a power drive motor module with a rotary output shaft. A releasable clamping mechanism is provided for positioning and holding cylindrical members to be welded in an axially aligned relationship with their ends abutting in a single plane. A safety interlock mechanism is provided for sensing the releasable clamping mechanism in an operative position to prevent inadvertent operation or operation of the welding unit when the clamping mechanism is malaligned.

Orbital welding apparatus with safety interlock

An orbital welding apparatus comprising a modular weld head unit including a circular rotor carrying a welding electrode for rotation about an axis for welding abutting ends of tubular members positioned in alignment on the axis. A drive assembly for driving the rotor includes a motor unit carried in a separate modular housing for ready manual connection and disconnection from the weld head unit. In the preferred form a transmission module is connected with the motor unit and connects to the weld head unit by a flexible drive shaft assembly to allow the motor unit to have substantially any desired orientation relative to the weld head unit. There is also disclosed a separate clamping assembly for holding the tubular members relative to the weld head unit.
