Title (EN) LATERAL SEAL FOR BLOWOUT PREVENTER SHEAR BLOCKS
(FR) JOINT D'ÉTANCHÉITÉ LATÉRAL POUR BLOCS DE CISAILLE DE BLOC OBTURATEUR DE PUITS
Abstract:
(EN) Present embodiments of the disclosure are directed to a seal assembly for generating a seal between two opposing shear blades of a ram unit after shearing a tubular. The seal assembly may include at least a wiper, a sealing element, and an energizer. The wiper may clean a surface of a shear blade as the blade moves relative to the seal assembly. The sealing element may include an elastomeric material that can be deformed into engagement with the shear blade to generate the seal. The energizer may be a hard component that energizes the sealing element against the cleaned surface of the shear blade as the blade moves further relative to the seal assembly. The wiper may clean the sealing surface of the blade by removing debris from the surface prior to the energizer activating the seal, thus enabling a more secure seal to be established on the blade surface.
(FR) Des modes de réalisation de la présente invention portent sur un ensemble joint d'étanchéité destiné à assurer un joint d'étanchéité entre deux lames de cisaille opposées d'une unité à vérin après cisaillement d'un élément tubulaire. L'ensemble joint d'étanchéité peut comprendre au moins un essuyeur, un élément d'étanchéité et un dispositif d'activation. L'essuyeur peut nettoyer une surface d'une lame de cisaille alors que la lame se déplace par rapport à l'ensemble joint d'étanchéité. L'élément d'étanchéité peut comprendre un matériau élastomère qui peut être déformé en prise avec la lame de cisaille pour produire le joint d'étanchéité. Le dispositif d'activation peut être un élément matériel qui active l'élément d'étanchéité contre la surface nettoyée de la lame de cisaille alors que la lame se déplace encore plus par rapport à l'ensemble joint d'étanchéité. L'essuyeur peut nettoyer la surface d'étanchéité de la lame en retirant les débris de la surface avant que le dispositif d'activation active le joint d'étanchéité, ce qui permet ainsi de former un joint d'étanchéité plus sûr sur la surface de la lame.
