摘要： A pressure relief device and a hydraulic fracturing system having a pressure relief device are provided. In one form, the pressure relief device has a valve body with a linearly extending throughbore between the inlet and outlet thereof. A rupture disc is secured in the valve body so that a frangible dome wall portion thereof has a reverse-acting orientation in the valve body bore. The hydraulic fracturing system includes a pump and a delivery line that receives pressurized fracturing fluid from the pump and delivers it to a well. A pressure relief device is installed along the delivery line. A sensor detects fluid flow downstream of the pressure relief device which allows the pump to be shut down when the downstream fluid flow is detected. The pressure relief device can have a body with a domed rupture disc and the sensor therein.

摘要： The present invention provides an improved method of manufacturing a rupture disk and specifically of forming a score on a rupture disk. The method of the present invention includes the rotating of a rupture disk blank relative to an electrical discharge machining or “EDM” cutting wire and the simultaneous moving of the EDM cutting wire toward the axis of the disk while maintaining the wire in a selected position such as generally parallel to the disk peripheral skirt or flange. The rotation of the disk and the movement of the EDM wire can be precisely controlled with the motion system of a commercially available EDM machine. With the present invention, a precise score is cut a partial distance through the disk thickness and preferably on the convex side of the dome, near the transition from the dome to the flange and in a generally “c” shaped pattern. The formed score creates a pattern of weakness so that the disk will open in either of the forward or reverse buckling direction. Score patterns other than the “c” shaped pattern could be cut.

摘要： An overpressure indicating disk apparatus for indicating an over pressure condition in a pressurized system includes a body having first and second end portions and a bore, the first end portion configured for attachment to the pressurized system and in pressure communication therewith so that the pressure in the bore is the same pressure as the pressure of the pressurized system. A reverse buckling disk having an annular peripheral portion and a concave convex dome portion is provided. The annular peripheral portion surrounds the dome. The disk annular peripheral portion is mounted to the body, closing the bore at the first end portion. An indicating component or ring is affixed to the combination of a body and reverse buckling disk. The indicating ring has an annular peripheral portion that aligns generally with the annular peripheral portion of the reverse buckling rupture disk. A movable central tab portion is mounted inside the indicating component or ring. A hinge connects the central tab portion to the indicating ring. The concave side of the reverse buckling disk faces the central tab. The convex side of the reverse buckling disk faces the pressure inside the bore. When the pressure in the bore exceeds a preselected maximum pressure value, the disk reverses to engage and displace the central tab thereby indicating visually that an overpressure condition exists within the bore.

摘要： In one form, a vent apparatus includes an inlet frame, a venting member, and a retainer member. The venting member includes a mounting portion, a weakened area or burst slit, and a domed portion. The mounting portion of the venting member is secured between the inlet frame and the retainer member. The retainer member includes vent retainer portions or tab portions that extend over the burst slit. The vent apparatus is configured to burst when an inlet pressure exceeds a predetermined level, where the tab portions will bend away and the venting member will bend past the tab portions to relieve the pressure. The inlet frame is configured to support against a vacuum pressure acting in the opposite direction, with the tab portions generally free from the load caused by the vacuum pressure.

摘要： A rupture disc device and method of assembly thereof are provided. The rupture disc device has a device body formed so that there are no leakage pathways to the radially outer surface thereof. The rupture disc is welded to the device body so that the weld joint therebetween is not relied upon to provide structural support, and instead strictly acts as a seal. In one form, the weld joint is formed with the weld beam directed axially transverse to thickness of the rupture disc to minimize unwanted variances in the rupture disc burst pressure that otherwise may be created due to the heat generated during weld joint formation.

摘要： A rupture panel of three layers employs a lower layer (e.g. foam) that is adhesive, a middle layer (e.g. metallic) and a hold down layer. The middle layer has a weakened portion (scoring, openings, for example) that defines the panel burst pressure. A part of the lower layer does not connect to the middle layer. That part that does not connect to the middle layer adheres to the hold down layer. The hold down layer can be in the form of a ring with an open center, the weakened portion of the middle layer occupying a position within the open center of the hold down layer.
