A designing apparatus comprises symbol mark memory for storing fluid controllers usable in fluid control devices in terms of symbol marks representing the functions, fluid channels and contours of the controllers, and a flowchart preparing device for preparing a flowchart of a fluid control device represented by symbol marks. The flowchart preparing device successively selects controllers, such as valves and massflow controllers, from a symbol mark file in the memory, arranges the selected controllers on a screen as suitably positioned, automatically selects a suitable coupling member for interconnecting adjacent two of the controllers from a coupling member data file and automatically arranges te controllers and the coupling members thus selected to prepare a flowchart.

Apparatus for and method of designing fluid control devices

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.

Fluid control apparatus

A valve main body is internally formed with a main channel extending from a rear end face thereof nearly to a first valve actuator, and two subchannels communicating with the main channel via second and third valve actuators, respectively. The valve main body has a slanting face extending forwardly downward and having the first valve actuator mounted thereon.

Shutoff-opening devices and fluid control apparatus comprising such

A device for heating a fluid control apparatus comprises a tape heater disposed on at least one of opposite lateral sides of the fluid control apparatus, and a plurality of brackets each comprising a bottom wall fastened to a panel with a screw and at least one side wall for holding the tape heater in contact with a fluid controller. The bottom wall of each of the brackets is formed with a screw hole, and each bracket is attached to the panel and adjustable in position.

Device for heating fluid control apparatus

A valve mount having two valves removably installed thereon from above as arranged in a direction comprises an inflow channel forming member having a channel in communication with an inlet of the valve disposed at one end thereof, a communication channel forming member having a channel for causing an outlet of the valve at the end to communicate with an inlet of the other valve adjacent thereto, an outflow channel forming member having a channel in communication with an outlet of the other valve, and a subchannel forming member having a channel in communication with an inlet-outlet port formed in the other valve.
