Abstract
A rupture disk assembly comprises: a single-part or multi-part body with an opening that forms an outlet for a conduit or a container; a rupture disk that closes the opening and bursts subject to the action of a rupture pressure in order to unblock the opening; an actuator to reduce the rupture pressure, wherein the actuator includes a plunger to reduce the rupture pressure on the rupture disk, the plunger being configured to strike against the rupture disk; and a housing to receive the actuator, the housing including a housing opening for the plunger.
Claims19
A rupture disk assembly, comprising:
- a single-part or multi-part body with an opening that forms an outlet for a conduit or a container, the body including a main bore extending from an inlet to the outlet and a threaded bore that intersects the main bore;
- a rupture disk that closes the opening and bursts subject to action of a rupture pressure in order to unblock the opening;
- an actuator located on a pressure side of the rupture disk to reduce the rupture pressure, wherein the actuator includes a plunger to reduce the rupture pressure on the rupture disk, the plunger being configured to strike against the rupture disk;
- a housing to receive the actuator and being screwable into the threaded bore of the body and projecting into an inner space defined by the main bore, the housing including a housing opening for the plunger;
- and
- a cover to close the housing opening, wherein the cover and the actuator are adapted to one another such that, upon actuation of the actuator, a force acting on the plunger of the actuator is sufficient to pierce the cover and to strike against the rupture disk.
A rupture disk assembly, comprising:
- a single-part or multi-part body with an opening that forms an outlet for a conduit or a container;
- a rupture disk that closes the opening and bursts subject to action of a rupture pressure in order to unblock the opening;
- an actuator located on a pressure side of the rupture disk and not in contact with pressurized medium to reduce the rupture pressure prior to an actuation, wherein the actuator includes a plunger to reduce the rupture pressure on the rupture disk, the plunger being configured to strike against the rupture disk;
- a housing to receive the actuator, the housing including a housing opening for the plunger,
- wherein the body includes a first side of a hollow cylindrical section that defines a main bore extending from an inlet to the outlet, the hollow cylindrical section being connected to a flange of the body on the first side and closed by the rupture disk adjacent to the flange and the hollow cylindrical section including a threaded bore into which the housing is inserted, the threaded bore intersecting the main bore, and
- wherein a second side of the hollow cylindrical section of the body comprises connecting structures for connecting to the container;
- a cover to close the housing opening, wherein the cover and the actuator are adapted to one another such that, upon an actuation of the actuator, a force acting on the plunger of the actuator is sufficient to pierce the cover and to strike against the rupture disk;
- and
- a screw cap to mount the cover on the housing.
