    摘要: A rupture disk with an annular flange that permits the disk to be clamped in place in a pressure system between an outlet holder and an inlet holder. The rupture disk is characterized by an eccentric score line formed on its annular flange radially outwardly beyond the dome of the rupture disk. A spacer and support ring are utilized to assist in the removal of that portion of the annular flange of the disk which ruptures from between the outlet holder and inlet holder.

    摘要: A "slip-joint" type of sensor having a tab design consisting of a unique shape which permits easy manufacture, low resistance to sliding forces, and reliable electrical contact. The unique switch or tab and body design provides positive electrical contact without the need for costly, full diameter, annular sheet metal rings. The sensor body lies in a single common plane and may have a variety of shapes depending on the flow rate to be permitted without tripping the sensor. The sensor may be hermetically sealed by a thin-film polymer liner to permit no flow through the sensor without a signal. The liner may be on either or both sides of the sensor. This design permits use of the liner designed to withstand a static pressure without bursting. At the static pressure, however, the liner will be deformed sufficiently to trip the sensor.

    摘要: The present invention relates to a safety pressure relief apparatus comprised of a reverse buckling rupture disk having a concave-convex portion connected to an annular flat flange portion by a curved transition connection and a support member having an annular flat flange portion for engaging the annular flat flange portion of the rupture disk and for supporting the transition connection thereof. The support member includes a partially circular cutting edge positioned interiorly of the transition connection and forming, in conjunction with a non-cutting interior edge, an opening in the support member so that when the concave-convex portion of the rupture disk reverses itself, the cutting edge partially severs the disk whereby a portion thereof bends about an unsevered hinge portion and passes through the opening in the support member. The hinge portion of the rupture disk is supported by the non-cutting interior edge of the support member. An improved serrated cutting edge is included having rounded notches between adjacent teeth thereby providing a cutting edge with fewer stronger teeth extending a shorter distance so that the available flow area through the opening in the support member is increased.

    摘要: Structure supporting apparatus which for a particular nominal size can be interchangeably sealingly clamped and centered between bolted flanges of varying pressure rating and design standard. The apparatus includes at least one support member having opposite parallel sides for sealingly engaging the seating surfaces of the flanges, a centrally positioned opening extending through the member and through the sides thereof for positioning structure supported thereby in alignment with the flow passageways in the flanges, the periphery of the support member being substantially square shape and including a pair of spaced apart recesses disposed in each of the four sides forming the substantially square shaped periphery thereof.
