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 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 pipe joint comprises a pair of tubular joint members made of a metal and each having an abutting end face, an annular gasket made of a metal and interposed between the abutting end faces of the respective joint members, a nut joining the joint members together and a retainer holding the gasket to one of the joint members. The joint members are made of stainless steel and silver white. The retainer is made of stainless steel and colored blue so as to be discernible from the joint members. The joint can be checked for the presence of the retainer, accordingly for the presence of the gasket, merely by discerning whether the color seen through an inspection window is blue or silver white.

摘要： A regulator for regulating a flow rate is provided with an upper connector having a downwardly opened channel in communication with the regulator. An on-off valve connected to the regulator is provided with a lower connector having an upwardly opened channel in communication with the on-off valve. The upper connector is lapped over the lower connector and removably joined thereto with a screw so as to cause the downwardly opened channel to communicate with the upwardly opened channel. Accordingly, the regulator can be removed singly, for example, when malfunctioning.

摘要： Bolt bores in lower members each comprise a large-diameter portion larger than the head of a bolt in diameter, and a small diameter portion extending downward from the large-diameter portion with a stepped portion formed therebetween and having a diameter intermediate between the diameter of the bolt head and the diameter of the shank of the bolt. A heat insulator has a spacer inserting hole. A hollow cylindrical spacer having an inside diameter larger than the diameter of the bolt shank is inserted through the small-diameter portion of the bolt bore and the spacer inserting hole so that the upper end of the spacer is positioned in the large-diameter portion. The spacer has a lower end bearing on a support member. A hollow cylindrical elastic member is interposed between the bolt head and the stepped portion for biasing the lower member toward the support member.

摘要： A method is provided for tightening up threaded members with proper tightening torque free of unequivalent tightening. In tightening a plurality of threaded members by drive means, the amount of tightening and tightening torque of each threaded member are detected as the members are progressively tightened, and when the tightening amount of each member has reached a value within a specified range, the difference in tightening torque between the threaded members is checked as to whether it is within a predetermined range.
