摘要： A control valve comprises a valve body having a fluid channel and a valve seat; a valve operating part; a valve stem supporting member having its upper end fixed to the valve operating part and its lower end fixed to the valve body; a valve stem penetrating the valve stem supporting member and having its upper end part connected to the valve operating part and its lower end part entering the valve body, the valve stem being movable upward or downward by the valve operating part; and a valve element attached to the lower end of the valve stem. The valve element is moved upward or downward by moving the valve stem upward or downward, the valve element being brought into contact with and seated in the valve seat to close a fluid channel as it is moved downward, the valve element being detached from the valve seat to open the fluid channel as it is moved upward. The valve stem supporting member has an upper tubular body and a lower tubular body, the upper tubular body having its upper end fixed to the valve operating part and its lower end detached from the valve body, the lower tubular body having its lower end fixed to the valve body and its upper end detached from the valve operating part, the two tubular bodies being spaced apart each other, the lower end part of the upper tubular body and the upper end part of the lower tubular body being connected by a connecting member.

摘要： A control valve comprises a valve body having a fluid channel and a valve seat; a valve operating part; a valve stem supporting member having its upper end fixed to the valve operating part and its lower end fixed to the valve body; a valve stem penetrating the valve stem supporting member and having its upper end part connected to the valve operating part and its lower end part entering the valve body, the valve stem being movable upward or downward by the valve operating part; and a valve element attached to the lower end of the valve stem. The valve element is moved upward or downward by moving the valve stem upward or downward, the valve element being brought into contact with and seated in the valve seat to close a fluid channel as it is moved downward, the valve element being detached from the valve seat to open the fluid channel as it is moved upward. The valve stem comprises an upper bar-shaped member of metal connected to the valve operating member and a lower bar-shaped member made of a fiber reinforced plastic to which the valve element is attached. The upper and lower bar-shaped members are movable upward from a lower end position where the valve element is in a fully open state. The lower bar-shaped member is stop from moving upward at an upper end position where the valve element is in a fully open state. An uppward moving distance of the upper bar-shaped member from a lower end position is made longer than a moving distance of the lower bar-shaped member from the lower end position to the upper end position.

摘要： A fluid flow control valve is provided with a seal comprising a thin metallic film backed by a resiliently deformable body. The seal is mounted on a closure part which may be either the valve stem or the valve seat. The thin film and deformable body are deformed so as to conform to the surface the metallic film seals against as the valve is closed. As the valve is opened, the deformable body returns to its initial state thus returning the thin film to its initial state.

摘要： A pipe joint comprises a pair of tubular joint members, an annular gasket interposed between abutting end faces of the joint members, and a nut for joining the joint members. A seal projection is formed on the abutting end face of each joint member at a position radially outward of an inner periphery of the end face. When an end of the seal projection is brought into contact with an end face of the gasket by tightening the nut, a clearance is formed between an outer flat portion of the abutting end face of each joint member and the gasket end face opposed thereto. The clearance is greater than a clearance between an inner flat portion of the abutting end face of each joint member and the gasket end face opposed thereto, and is eliminated when the nut is completely tightened up.

摘要： A diaphragm valve comprises a body having an inflow passage, outflow passage, valve chamber and valve seat, a metallic diaphragm for maintaining air-tightness of the valve chamber, a bonnet for securely holding the edge portion of the outer circumference of the metallic diaphragm in cooperation with the body, a stem inserted through and supported by the bonnet but movable up and down, and a valve disk inserted through a center opening in the metallic diaphragm. The valve disk comprises a seat portion of disk-like shape contacting with and moving away from the valve seat, a shaft portion provided on the top surface of the seat portion and inserted through the opening in the diaphragm, and a connecting portion provided at the top end of the shaft portion and connected to the bottom end portion of the stem. An end edge portion of the inner circumference of the diaphragm is welded to the disk valve shaft portion over the entire circumference of the shaft portion at a location spaced from the seat portion so that a large gap exists between the upper surface of the seat portion and the lower surface of the diaphragm, thereby improving gas substitution performance.

摘要： Flaws in a fluid controller caused by nonmetallic inclusions in material during machining of a contact surface of a valve seat are prevented by forming the valve seat of corrosion-resistant high-cleanliness material. The valve seat of the fluid controller is formed from corrosion-resistant alloy with 0.05% or less cleanliness and containing in weight ratio 12.90-15.00% Ni, 16.50-18.00% Cr, 2.00-3.00% Mo, 0.02% or less C, 0.30% or less Si, 0.40% or less Mn, 0.03% or less P, 0.003% or less S, 0.25% or less Cu, and 0.01% or less Al. Fluid leakage is almost completely prevented (100%) by such a valve seat.

摘要： A diaphragm valve comprises: a body (1) having an inflow passage (1a), an outflow passage (1b), a concave valve chamber (1c) and a valve seat (1d); a metallic main diaphragm (2) which holds airtightness of the valve chamber (1c) and makes contact with and separates from the valve set (1d) directly or indirectly; a bonnet (4) which securely holds an outer circumferential edge portion of the main diaphragm (2) between the body 1 and the bonnet 4; and a stem 5 which causes the main diaphragm (2) to be deformed elastically. At the top surface side of the aforementioned main diaphragm (2) there is arranged a metallic sub-diaphragm (3) whose outer circumferential edge portion can be elastically deformed in a vertical direction. A center portion of the aforementioned sub-diaphragm (3) is fixed to a center portion of the main diaphragm (2), so that the sub-diaphragm (3) comes in contact with the top surface side of the main diaphragm (2) to support a bend thereof when the main diaphragm is deformed elastically.

摘要： A liquid crystal shutter includes a first support substrate having a first electrode and a second support substrate having a second electrode opposite to the first electrode. A liquid crystal layer is sandwiched between the first and second electrodes so as to have a switching region. The switching region becomes a bend alignment state from a splay alignment state when a voltage is applied to the liquid crystal layer. A nucleus region formation portion is arranged on the first support substrate to form a nucleus region in the switching region corresponding to the nucleus region formation portion in the liquid crystal layer, in which the splay alignment is more stable than in the switching region.
