The present invention provides a fluid device coupler which can achieve satisfactory workability while saving space without reducing sealing performance, wherein the fluid device coupler comprises a coupling base having a depressed part at least partially curved in an arc shape, a first end edge side and a second end edge side continuous with an inner surface of the depressed part, and an opening portion formed between the first end edge side and the second end edge side a blockage member protrudable from the first end edge side toward the second end edge side and retractable in a circumferential direction from the second end edge side toward the first end edge side, and a sliding structure configured to slidably move the blockage member toward the second edge side of the coupling base without changing a distance radially from the coupling base.

Fluid device coupler and fluid device coupling structure

The present invention provides a checking tool for a tube coupler with which it is possible to visually check an attachment state of the tube coupler. A checking toolfor a tube coupler according to the present invention is a checking tool configured to be attached to a tube coupler, the tube coupler being formed of a first coupling pieceand a second coupling piecehingedly connected to each other so as to be able to be opened and closed, being configured to couple tubes to each other with use of the first coupling piece and the second coupling piece, and having hook piecesandthat are provided protruding from outer circumferential surfaces of the first coupling piece and the second coupling piece. The checking tool includes a pair of longitudinal framesthat conform to an outer circumferential surface of the tube coupler, a first lateral framethat connects end portions at one end of the pair of longitudinal frames to each other, a second lateral framethat connects end portions at the other end of the pair of longitudinal frames to each other, a first claw piecethat is provided protruding from the first lateral frame toward the second lateral frame, and a second claw piecethat is provided protruding from the second lateral frame toward the first lateral frame.

Checking tool for tube coupler

The present invention provides a clamping jig for tube connection with which it is possible to clamp tubes even in a small and narrow space. A clamping jig for tube connectionaccording to the present invention is a clamping jig for tube connection that clamps joint-equipped tubes, each tube including a protruding collar portionat a position rearward of its leading end. The clamping jig for tube connection includes: a first memberthat includes a first clamping portionthat is provided at a leading end thereof and to which one of the tubes is fitted, and a first gripping portionformed at a base end thereof, a second memberthat includes a second clamping portionthat is provided at a leading end thereof and to which the other tube is fitted, and a base end thereof being pivotally supported at the base end of the first member by a pivoting portion; a support rodthat extends from the first member through the second member; and a lever memberin which a leading end thereof is pivotally supported by a support portionprovided in the support rod, and a lever gripping portionis formed at a base end thereof, the lever memberenabling swinging of the lever gripping portion in a direction of the base end of the second member, and the lever memberincluding a pressing portionthat presses the second member on the base end side relative to the support portion.

Clamping jig for tube connection

In a connected-part seal structure configured to couple a first connected part and a second connected part through a seal member, the taper angles of first and second inner pressure-contact tapered parts provided in the seal member are smaller than the taper angles of first and second inner tapered parts provided in the first and second connected parts. Thus, a pressure-contact force of first and second inside tapered pressure-contact allowances are larger as the inside tapered pressure-contact allowances are located closer to base end parts of first and second annular protrusions.

Connected part seal structure, and seal member

A fluid-device connecting structure includes a first fluid device having a first connection part, a second fluid device having a second connection part, an annular seal member to connect the first and second connection parts, and a coupling member to keep the first and second connection parts in a connected state. The coupling member includes a first coupling segment and a second coupling segment, each including at one end a first hinge part or a second hinge part. The first and second connection parts each have a cylindrical outer shape. The first coupling segment has a U-like shape having an opening and surrounds the first and second connection parts over a range more than 180 degrees of an entire circumference of each of the first and second connection parts.

Coupling member, fluid-device connecting jig, and fluid-device connecting structure

A fluid control device manifold includes a first body, a second body, and a connection part configured to interpose a seal member between the first and second bodies and allow a connecting tool to engage with engagement surfaces of the bodies. When a load is applied to the engagement surfaces to draw the first and second bodies close to each other, the seal member is press-fitted into the bodies. This press-fitted state is held by a clamp. One or both of the first and second bodies are internally provided with a plurality of the engagement surfaces extending in a nearly perpendicular direction to a drawing direction.

Fluid control device manifold, manifold assembling method, and connection tool

A fluid control valve includes: a valve main body including an inlet port and an outlet port, each being formed on opposite side surfaces; and a mounting plate attached to a lower end of the valve main body; wherein the valve main body has side surfaces located perpendicular to the opposite side surfaces and formed with locking protrusions, the mounting plate is formed with locking arms each extending from an upper end of the mounting plate, the locking arms each having a locking pawl facing and engaging with the protrusion, the valve main body is formed with an annular rib about an central axis on the lower end of the valve main body, and the upper end of the mounting plate is formed with a press-fit rib including a press-fit portion press-fitted in a wall surface of the annular rib.

Fluid control valve

A fluid control valve includes: a resin valve main body including inlet and outlet ports in opposite side surfaces, a valve chamber communicating between the inlet and outlet ports and opening at the upper surface center of the main body, and a valve seat provided in an inner wall of the chamber; a valve element movable into or out of contact with the valve seat; and a valve upper body including a drive part to drive the valve element. An inflow passage is formed like an L shape extending through the inner wall to communicate between the inlet port and the chamber via the valve seat. The inner wall is cylindrical having a thick-wall portion to have a wall thickness thicker on the inlet port side than on the outlet port side. The valve main body is provided, at a center of a lower surface, with a resin injected part.

Open/close valve

A diaphragm valve having a diaphragm valve element including a valve element body movable into contact with a valve seat, a web portion extending outward from the valve element body, and a fixed portion formed at an outer peripheral edge of the web portion. The web portion includes a vertical portion vertically formed continuous with the valve element body, a horizontal portion horizontally formed continuous with the fixed portion, and a connecting portion of a circular arc shape (an upward protruding shape) in section to connect the vertical portion with the horizontal portion, thereby holding the vertical portion in constant contact with an outer surface of a backup.
