The method may also include aligning an alignment tab of the nut with the axial slot, engaging the nut with the one or more threads while the alignment tab is aligned with the axial slot, and rotating the nut 45-270.

A fluid passage device including a passage for flowing high-pressure fluid of a predetermined or higher pressure comprises a sac bore cylinder of a metal, which includes therein a closed passage and a branch passage. The closed passage is shaped to extend straightly in a predetermined direction and has a closed top end, and the branch passage is branched off from the closed passage. A top end part of the closed passage at a closed side is defined by a ceiling wall surface, which is perpendicular to the predetermined direction, a passage wall surface, which is parallel to the predetermined direction, and a connecting wall surface, which connects the ceiling wall surface and the passage wall surface. The connecting wall surface is shaped to curve in a direction to expand the closed passage.

A valve plug assembly includes a plug base, a first end of the base arranged for attachment to a valve stem, a second end of the plug base including a bore having a first portion and a second portion. The second portion of the bore is a conical terminus forming a first seat. A spacer has a through bore, a first end, and a second end, and is sized for insertion in the bore of the plug base and has a conical shape to engage the first seat, and the spacer also forms a second seat. A plug tip has a through bore and a conical end engaging the second seat and is arranged to engage the valve seat, and a cap screw extends through the plug tip and the spacer to mechanically secure the plug tip to the plug base.

A thermo valve is configured by coupling a valve body to a thermo actuator via a coupling part. The valve body has at least two recesses extending in a peripheral direction. The thermo actuator and the valve body overlap each other in a direction of an axial centerline to cover at least one of the recesses. The coupling part is formed by at least a certain section of the overlapping portion being depressed toward the axial centerline and another section of the thermo actuator fitting in the recesses. The depression of the coupling part has a shape elongated in a longitudinal direction along the axial centerline.

The present invention generally relates to assembly equipment of valve body, especially to riveting and grinding assembly for nozzle of screw shaft valve. The invention may include a rack, a power control box, a turntable and a turntable divider. A carrier assembly which engages with the screw shaft valve body is installed on the edge of the turntable with uniform distribution. On the center part of the turntable, a support shaft which is installed on and fixed with the rack is vertically interposed and on the top of the support shaft, an upper supporting disc is installed. A valve pipe feeding device, a valve pipe preloading device, a valve pipe riveting device and a valve pipe grinding device which engage with the carrier assembly are installed on the said rack on the rotational direction of turntable. As the threaded pipe is put into the carrier assembly by valve pipe feeding device, the carrier assembly rotates counterclockwise along the turntable and rotates to the valve pipe feeding device to the press threaded pipe into the valve seat. Thereafter the carrier assembly rotates the valve pipe riveting device and rivets threaded pipe with a valve flange in order to finish assembling process. Finally, the carrier assembly rotates the valve pipe grinding device to grind nozzle of valve to finish grinding and riveting process of threaded pipe with high positioning accuracy of assembly and marvelous hermetic sealing.

A method for mounting a valve needle and a bearing bush in an expansion valve for an air conditioning system may including providing a bearing bush and providing a valve needle. The bearing bush may include a circumferential wall. The valve needle may include a mounting groove having two groove flanks and a groove base. The method may also include forming a needle-bush arrangement in which the bearing bush may be received in the mounting groove via one of (i) axial sliding-in the valve needle into the bearing bush and (ii) axial sliding-on the bearing bush onto the valve needle. The method may further include mounting the needle-bush arrangement in a mounting bore of the expansion valve, which may include (i) forming a press fit between the circumferential wall and the mounting bore, and/or (ii) forming a clearance fit between the groove base and the bearing bush.
