The fluid delivery apparatus includes one or more modular subassemblies having an upper module, a lower module, and a base block. The upper module includes a passageway for coupling with a fluid handling component such that the upper passageway is in fluid communication with the fluid handling component. The lower module includes a lower passageway for coupling with the upper module such that the passageways are in fluid communication. The lower module includes a flow channel having a lower passageway. The base block includes a receptacle and a channel. The upper module is received within the receptacle and the lower module extends through the channel. The modular subassembly can include a spacer having a plurality of alignment apertures for aligning fluid coupling ports of the upper and lower modules. A method of using the fluid delivery apparatus is also disclosed.
摘要:
A pressurization control device (10) for controlling positive pressurization of an electronic equipment enclosure, such as, for example, a telecommunications equipment enclosure (12 or 14), wherein the device (10) combines and integrates a number of valves or other control components and functions into a single, common valve body (28) or manifold providing a single, shared penetration point (54) into the enclosure (12 or 14), thereby advantageously minimizing the number of penetrations into and potential leakage points from the enclosure (12 or 14). The valves or other control components may be substantially conventional and may include, for example, a cable air tube connection fitting (30); a pressure cutoff valve (32); a pressure relief valve (34); and a static pressure valve or air stem (36); an express fitting (38); and an on/off valve (40).

A MicroMount™ System for providing reliable, self-aligning connections to external fluid-handling or fluid-sensing components is disclosed. One embodiment comprises a generally miniaturized rectilinear body (102) that includes a plurality of exterior side walls (103). The upper wall (104) has a port (108) which is configured to connect to an external component. The end of the same port (108) which extends to the lower wall (105) is connected to an external passageway (107). The rectilinear body (102) does not require holes or fasteners that fit into holes, since it employs a number of posts (110) that project from the body (102) to secure the body (102) to an external component.
摘要:
An on-off device disposed at each of the inlet and the outlet of a fluid controller is one of five kinds of on-off devices, i.e., on-off device having a two-port valve, on-off device having a two-port valve and a three-port valve, on-off device having a two-port valve and two three-port valves, on-off device having two three-port valves, and on-off device having three three-port valves, The main bodies of two-port valves of all types of on-off devices are identical in configuration and each have an inlet and an outlet in a bottom face thereof. Main bodies of three-port valves of all types of on-off devices are identical in configuration and each formed in a bottom face thereof with an inlet, an outlet always in communication with the inlet, and an inlet-outlet subopening.
摘要:
A novel stream switching system includes a unitary housing having a common stream path for a multitude of fluid streams from, for example, a process pipeline. A set of solenoids or other switches attached to the housing directly controls the flow of each fluid stream. Preferably, the solenoids are default-closed, low dead-volume solenoids that, unlike conventional low dead volume solenoids, are closed if not supplied with electricity. These solenoids are adapted to the wide temperature ranges encountered in the pipeline environment by increasing the voltage applied to the solenoids. The housing also preferably includes a pre-heat region to warm the sample to a desired temperature.

A multiple output modular pneumatic pressure valve has a plurality of modules connected together. Each module has a regulator, shuttle valve and four way solenoid actuated spool valve for provides a plurality of pneumatic pressures to a single outlet which may be quickly selected via the actuation and deactuation of the proper valves. Adjustment of the pneumatic pressures can be easily performed by rotation of a knob of the pressure regulator.

The module for an electrohydraulic transmission controlling device includes a plurality of magnetic valves (16,17) arranged in a housing (12). The housing (12) includes a control block (24) and a cover (22) for the control block (24). The cover (22) is made by a MID casting method and the control block (24) is made by a thixotropic casting process. Component groups (14), especially a resistor (18), a switch (20) and magnetic valves, are arranged in the housing (12). By making the cover in a MID casting method and the control block by a thixotropic casting process the manufacture of the module is more economical and the assembly is simplified.
摘要:
A manifold solenoid valve drive-controlled by serial signals permits extremely easy assembly and easy maintenance, and eliminates a possibility of erroneous wiring. For this purpose, compressed air is supplied and exhausted through manifold blocks 30 on which solenoid valves 20 are mounted and which are consecutively connected, and serial signals are transmitted to the respective solenoid valves. A fluid passage section 31 of the manifold block is provided with common passages 32 and 33 for air supply and exhaust that penetrate the respective manifold blocks 30, and channels 36 through 38 that communicate them with supply/discharge openings of the solenoid valves 20. In an electric circuit section 41 of the manifold block, a printed circuit board 45, which has connecting terminals 46a and 46b for transmitting serial signals, slave chips 47 for extracting operation signals for the solenoid valves from serial signals, and a feeder terminal 49 for supplying power to the solenoid valves 20 based on the operation signals, is accommodated. Assembling the manifold solenoid valve 10 completes communication of the passages and electrical connection.
