Beschreibung
Zusammenfassung:	A valve assembly for a hydraulic frac pump includes a valve body having a spherical sealing surface, a valve seat having a circular concave sealing surface that receives and accommodates the spherical sealing surface of the valve body. The valve seat forms a fluid passageway, where the fluid passageway is completely closed when the valve body is received and accommodated in the valve seat in a closed position. The valve assembly further includes a stopper disposed above the valve body to restrict movement of the valve body when it is lifted off of the valve seat in an open position. L'invention concerne un ensemble vanne pour une pompe de fracturation hydraulique, lequel ensemble comprend un corps de vanne ayant une surface d'étanchéité sphérique, et un siège de vanne ayant une surface d'étanchéité concave circulaire qui reçoit la surface d'étanchéité sphérique du corps de vanne et qui s'adapte à celle-ci. Le siège de vanne forme un passage de fluide, le passage de fluide étant complètement fermé quand le corps de vanne est reçu et adapté dans le siège de vanne dans une position fermée. L'ensemble vanne comprend en outre un bouchon disposé au-dessus du corps de vanne afin de limiter le déplacement du corps de vanne quand il est soulevé à partir du siège de vanne dans une position ouverte.
