Abstract: A pressure equalization device for a housing has a base body and a closure element with a flow path between them being open in a normal operating state of the pressure equalization device. A flow opening in the flow path is spanned by a membrane. An emergency venting spike projects from the closure element toward the membrane. The pressure equalization device transitions after emergency venting into an emergency operating state in which the closure element gas-tightly closes the base body. A housing with such a pressure equalization device is provided. In a method for pressure equalization with such a pressure equalization device between a housing interior and an environment, gas exchange between interior and environment is performed through the membrane and the flow path between closure element and base body. During emergency venting, the membrane is destroyed by the emergency venting spike. The closure element then closes the base body.

Abstract: Specified is a water supply apparatus, a mixing apparatus (1) being provided for mixing, in a mixing container (3), water conveyed in the mixing apparatus (1). Arranged relative to the mixing container (3) is a base apparatus (2) which has a base chamber (9) that is hydraulically connected to a water pipe (11, 12, 13) of the water supply apparatus and has an opening to the surroundings. A sealing device (10) is installed in the base chamber (9) for the purpose of closing off the opening of the base chamber (9) from the surroundings. The sealing device (10) has a weak point wall region (17) whose pressure strength is lower than the pressure strength of wall regions of all the other components of the water supply apparatus which, in the operating state, enclose cavities that can be filled with water, and which separate these cavities that can be filled with water from the surroundings.

Abstract: A valve arrangement includes a housing with an outlet and an inlet and having a poppet. The poppet has a stem and is movable within the housing along a movement axis between an open position and a closed position. The inlet is isolated from the outlet when the poppet is in the closed position. The inlet is in fluid communication with the outlet when the poppet is in the open position. The stem is inverted relative to the housing such that at least a portion of the poppet stem is disposed in the inlet when the poppet is in the open position.

Abstract: A chemical injection valve can include a valve stem reciprocably disposed relative to a primary seal, and a variable flow restrictor upstream of the primary seal relative to a direction of flow through the chemical injection valve. The variable flow restrictor restricts the flow when the valve stem is disengaged from the primary seal. A chemical injection system can include a chemical treatment pumped through a chemical injection valve and into an interior of a tubular string in a well, the chemical injection valve including a valve stem, a primary seal sealingly engaged with the valve stem in a closed position and disengaged from the valve stem in an open position, and a flow restrictor that restricts the flow of the chemical treatment downstream from the primary seal in the open position.

Abstract: A frangible valve is disclosed. The frangible valve can include an outer portion operable to form a pressure boundary for a pressure vessel. The frangible valve can also include an inner portion integrally formed with the outer portion and having a central region and a separation region about a perimeter of the central region proximate the outer portion. The separation region can have a thickness less than a thickness of the central region and can be configured to break at a predetermined fluid pressure inside the pressure vessel to vent pressure from the pressure vessel.
