Fluid processing apparatus has a prefabricated branched network of flexible tubing, for conducting process fluid between process elements of the apparatus, and control valves. A tubing support has opposable front and rear plates which define a pattern of support channels between them in which the flexible tubing network lies, so that the support channels limit or prevent expansion of the flexible tubes. Standard non-reinforced tubing can then be used for high-pressure work. The support body plates can be separated to open the channels for insertion or removal of the flexible tubing. The front plate may be transparent. The control valves operate by simply pressing on the tubing in the support channels to block flow, without invasion of the flow path. The tubing sets can be easily replaced, cleaned or sterilized. The invention is useful in a range of controlled-flow processes e.g. chromatography and filtration.

A valve manifold has a housing with a central mixing chamber and a shell surface. The shell surface of the valve manifold has at least two valve ports, with each valve port being associated with one valve. A first valve port has three openings, and additional valve ports each having three openings. A respective first opening of the valve ports is in direct fluid communication with the central mixing chamber, and the second and third openings of the valve ports are each in fluid communication with an inflow or outflow via a duct. A bottom of the mixing chamber, in relation to a plane arranged perpendicularly to a vertical longitudinal axis of the housing, has a slope towards the first opening of the first.

A tire inflation control system for a vehicle includes: a manifold defining: a channel configured to be connected to a fluid source, and a discharge port configured to be connected to one or more tires of a vehicle; an actuator configured to selectively control fluid communication between the channel and the discharge port; a pressure sensor configured to measure a fluid pressure in the discharge port; and an electronics module in communication with the pressure sensor and configured to command the actuator to selectively control fluid communication between the channel and the discharge port and based on the fluid pressure in the discharge port, and to thereby control inflation of the one or more tires connected to the discharge port.

A tire inflation control system for a vehicle includes: a manifold, an actuator, a pressure sensor, and an electronics module. The manifold defines: a channel for connection to a fluid source, a discharge port, an electrical connector housing configured to selectively couple to an external wiring harness. The actuator selectively controls fluid communication between the channel and the discharge port. The pressure sensor is configured to measure a fluid pressure in the discharge port. The electronics module has a multi-conductor interface with a plurality of conductors that extend to the electrical connector housing to provide connection to one or more external systems, and is in communication with the pressure sensor to command the actuator to selectively control fluid communication between the channel and the discharge port based on the pressure in the discharge port, to thereby control inflation of one or more tires connected to the discharge port.

A vehicle-mounted hydrogen supply method and device for hydrogen-rich smelting in a blast furnace or shaft furnace, combining steel plant hydrogen supply requirements with vehicle-mounted hydrogen supply technologies to construct a vehicle-mounted hydrogen supply system applied to hydrogen-rich smelting in a blast furnace or shaft furnace, thus providing an effective and reliable pathway for safe and stable hydrogen supply in a blast furnace or shaft furnace smelting process to perform hydrogen-rich smelting testing and production. Compared with a newly-built hydrogen plant, the invested construction cost is low, the operation flow is simple, the method and device are not limited by technical upgrading and transformation, and the flexibility is high. At the same time, two working long pipe vehicles and two pressure reducing system intake pipelines are used for solving the problem of continuous hydrogen supply required for hydrogen-rich smelting in a blast furnace.
