Provided is a fluid control apparatus in which a pipe heating member may be mounted or removed with flexibility (i.e., without affecting other components) while one line, composed of the plurality of fluid control devices arranged in series, as a unit may be added or modified readily. The apparatus includes: a plate-shaped support memberto which a plurality of passage blocksare detachably mounted; a hollow metal mounting memberhaving an upper surface to which the support memberis secured and being detachably mounted to a base member; and a pipe heating memberfitted into the mounting member. The pipe heating member, including a bottom walland a pair of side walls, accommodates a pipebetween the side wallsand is fitted into the mounting memberwith the pipe heating memberabutting the mounting member.

Fluid control apparatus

Provided is a fluid control device which can shorten an assembling time by facilitating positioning of a line support member and can suppress the increase of a height of a portion which supports fluid control equipment. A base member is formed in a rectangular frame shape by an upper lateral frame member, a lower lateral frame member, and left and right longitudinal frame members which are orthogonal to the upper and lower lateral frame members. A positioning portion for positioning each line support member is provided to the respective lateral frame members. Upper and lower end portions of each line support member are clamped between the respective lateral frame members and upper and lower cover members detachably mounted on the base member in a state where the upper and lower end portions of each line support member are positioned by the positioning portions provided to the respective lateral frame members.

Fluid control device

A fluid draw-off block joint includes an inlet channel, an outlet channel, and a closure portion. The inlet channel has a first end communicating with an outlet channel of a single-line block joint, and a second end communicating with an inlet channel of an outlet on-off valve. The outlet channel has a first end communicating with an outlet channel of the outlet on-off valve, and a second end being open through a side surface in a line exit direction. The closure portion closes an opening of a bifurcated channel of a plural-line block joint.

Fluid control apparatus joint, and fluid control apparatus

Two coupling members are provided in respective butting end faces thereof with annular recessed portions surrounding respective fluid channels thereof and having annular projections each formed in a bottom face of the recessed portion. A gasket comprises a sealing portion having an outside diameter smaller than the diameter of the recessed portions and is positioned between the projections of the coupling members, and a guide has an outside diameter permitting the guide to be fitted into the recessed portions and positioned externally of the sealing portion. The butting end faces of the coupling members are movable into contact with each other when the coupling is tightened up properly. The sealing portion has an annular groove formed in an outer periphery thereof, and the sealing portion and the guide are connected together by a snap ring fitted in the annular groove.
