    摘要: A valve has a valve seat, and a housing which accommodates the seat. The housing is formed from two sheet metal shells each of which has two sections. A first section of each shell defines a conical frustum, and the larger-diameter end of each frustum is bevelled. The second section of each shell is cylindrical and is seamlessly connected to the bevelled end of the respective first section so that the first and second sections of each shell are inclined relative to one another. The second sections have respective plane end faces which confront one another and are located in planes intersecting both the transverse and longitudinal axes of the valve. A circumferentially complete weld seam bonds the end faces to each other.

    摘要: A method of making light weight pressure actuated diaphragm control units from two thin preshaped resilient casing shells having clamping flanges diverging at an outwardly oblique angle from the hollow bodies of the shells by employing external cylindrical clamping devices and sufficient force to reshape the preformed diverging flanges by flattening them against the diaphragm and then welding the peripheral edges of this clamped assembly to permanently secure the clamping flanges in the flattened position for improved clamping of the diaphragm in the device and longer operating life.

    摘要: A diaphragm valve including a valve body, a diaphragm assembly and an actuator assembly having a housing body that isolates the actuator from the ambient atmosphere. The diaphragm assembly is welded to the valve body to reduce and/or eliminate fluid leakage around the diaphragm assembly. Additionally or alternatively, the housing body for the actuator assembly may be welded to the valve body to reduce fluid leakage. The welding may be performed using ultrasonic welding techniques.
