APPARATUS FOR MONITORING OF VALVES AND METHODS OF OPERATING THE SAME

A valve includes a valve stem assembly (214) including at least one wall and at least one passage (258) at least partially defined within the valve stem assembly. The at least one passage defines a first opening. At least one portion of the at least one wall defines an erosion site (260) that is con...

Beschreibung
Zusammenfassung:	A valve includes a valve stem assembly (214) including at least one wall and at least one passage (258) at least partially defined within the valve stem assembly. The at least one passage defines a first opening. At least one portion of the at least one wall defines an erosion site (260) that is configured to undergo contact with solid particles such that a second opening of the passage is defined. The valve also includes at least one sensing device (262) coupled in flow communication with the at least one passage through the first opening. The at least one sensing device is configured to transmit a signal representative of an increased fluid flow through the at least one passage. La présente invention concerne une soupape qui comprend un ensemble tige de soupape (214) comprenant au moins une paroi et au moins un passage (258) au moins partiellement définis dans l'ensemble tige de soupape. Le ou les passages définissent une première ouverture. Au moins une partie de la ou des parois définit un site d'érosion (260) qui est conçu pour subir un contact avec des particules solides de sorte qu'une seconde ouverture du passage soit définie. La soupape comprend également au moins un dispositif de détection (262) couplé en communication fluidique avec le ou les passages à travers la première ouverture. Le ou les dispositifs de détection sont conçus pour transmettre un signal représentant une augmentation de l'écoulement de fluide à travers le ou les passages.
