Kwishishini le-valve, ibhola ye-tungsten ye-carbide kunye ne-valve yeplagi zizixhobo ezimbini eziqhelekileyo zokuvula kunye nokuvala, nangona zombini zisetyenziselwa ukulawula ukukhutshwa / ukuvala umbane, kukho ukungafani okucacileyo kwisakhiwo, umsebenzi kunye neemeko zesicelo.
Ibhola yevalve ye-tungsten carbide, njengenxalenye ephambili yevalve yebhola, isakhiwo sayo silula. Ngokuqhelekileyo yibhola eyenziwe nge-carbide evula kwaye ivale ngokujikeleza i-90 ° malunga ne-axis yesiqu. Olu yilo lwenza ukuba ibhola yevalve ye-carbide ibe neenzuzo zokuchasana nokuhamba okuncinci kunye nokuvulwa ngokukhawuleza kunye nokuvala. Ivalve yeplagi isebenzisa umzimba weplagi onomngxuma ophumelayo njengoko indawo yokuvula kunye nokuvala, kunye nomzimba weplagi ujikeleza kunye nesiqu sevalve ukuphumeza isenzo sokuvula nokuvala. Umzimba weplagi wevalve yeplagi ubukhulu becala yikhowuni okanye isilinda, edityaniswa nomphezulu ohonjisiweyo wevalve womzimba wevalvu ukwenza iperi yokutywina.
Ngenxa yobuncinci bezinto zayo, ibhola yevalve ye-tungsten carbide inokumelana nokugqwesa okugqwesileyo kunye nokumelana nokugqwala, kwaye inokugcina ukusebenza okuzinzile kwiindawo ezinzima ezifana nobushushu obuphezulu kunye noxinzelelo oluphezulu. Ngexesha elifanayo, ibhola ye-carbide valve inokumelana nokuhamba okuncinci kunye nokuvulwa ngokukhawuleza kunye nokuvala, okufanelekileyo ngokukhethekileyo kwizihlandlo ezifuna ukunqumla ngokukhawuleza umbane. I-valve yeplagi ineempawu zesakhiwo esilula, ukuvulwa ngokukhawuleza kunye nokuvala, kunye nokuchasana kwamanzi aphantsi, kwaye unokudibanisa ngokukhawuleza okanye ukunqumla umbhobho kwiimeko ezingxamisekileyo ezifana neengozi. Xa kuthelekiswa nezivalo zesango kunye neglobhu, iivalve zeplagi ziguquguquka ngakumbi ekusebenzeni kwaye zikhawuleza ekutshintsheni.
Ngenxa yokusebenza kwayo okugqwesileyo, iibhola ze-tungsten carbide valve zisetyenziswa ngokubanzi kwiinkqubo zepayipi kwi-petroleum, iikhemikhali, amandla ombane kunye namanye amashishini, ngokukodwa kwiimeko ezifuna ukuvulwa rhoqo kunye nokuvala kunye nokulungelelanisa izinga lokuhamba. Ivalve yeplagi isetyenziswa kakhulu phakathi kunye nobushushu obuphantsi kunye ne-viscosity ephezulu kunye namacandelo afuna ukutshintshwa ngokukhawuleza, njengokunikezelwa kwamanzi asezidolophini, ukucocwa kogutyulo kunye nezinye iindawo.
