I-Trunnion vs I-Floating Ball Valve: Yeyiphi Efanelekileyo Kwisicelo Sakho

Kukho umahluko omkhulu phakathiIivalvu zebhola yeTrunnionkwayeIivalvu zebhola ezidadayongokwesakhiwo, umgaqo wokusebenza, ukusebenza kunye nezihlandlo zokusetyenziswa. Oku kulandelayo luthelekiso oluneenkcukacha lwazo zombini:

Umahluko kwisakhiwo seTrunnion kunye neFloating Ball Valve

Ivalvu yeBhola yeTrunnion

• Ibhola iqhagamshelwe ngokuqinileyo kwiziqu zevalvu eziphezulu nezisezantsi. Ibhola inokujikeleza kuphela kwi-axis yesiqu sevalvu kwaye ayinakuhamba ngokukhululekileyo emzimbeni wevalvu.
• Iziqu zevalvu eziphezulu nezisezantsi ziqhagamshelwe ngokuqinileyo kwibhola, nto leyo ethintela intshukumo yebhola.

Ivalve yeBhola edadayo

• Ibhola iyadada, oko kukuthi, akukho nxibelelwano luzinzileyo phakathi kwebhola kunye nesihlalo sevalvu, kwaye ibhola inokushukuma ngokukhululekileyo emzimbeni wevalvu.
• Ngokwesiqhelo isiqu esinye sevalvu esisezantsi siqhagamshelwe ebholeni, kwaye isiqu sevalvu esingaphezulu sidlala indima yokudlulisa i-torque kwaye asibambeki ngqo ebholeni.

Umgaqo Wokusebenza

1. Ivalvu yebhola yeTrunnion

• Ukulingana okuqinileyo kunye nokutywinwa phakathi kwebhola kunye nesihlalo sevalvu kwenziwa ngokulayisha kwangaphambili phakathi kwebhola kunye nesihlalo sevalvu kunye nokudluliselwa kwesiqu sevalvu.
• I-torque idluliselwa ngokulinganayo ebholeni ngokusebenzisa iziqu zevalvu ephezulu nesezantsi, kwaye ukujikeleza kwebhola kuthambile kwaye amandla alingana ngakumbi.

2. Ivalvu yebhola edadayo

• Xa ivaliwe, uxinzelelo oluphakathi lutyhala ibhola kwisihlalo sevalvu yokuphuma, ukuze ibhola kunye nesihlalo sevalvu zilingane kakuhle ukuze kufunyanwe ukutywinwa. Okukhona uxinzelelo oluphakathi luphezulu, kokukhona isiphumo sokutywinwa singcono.
• I-torque idluliselwa ikakhulu ebholeni ngesiqu sevalvu esisezantsi, kwaye isiqu sevalvu esingaphezulu sincedisa ekudluliseni. Ngexesha lenkqubo yokuvula nokuvala, imeko yamandla ebhola iyinkimbinkimbi.

Iimpawu zokusebenza

1. Ivalvu yebhola yeTrunnion

• Ukusebenza kokutywina okuzinzileyo, akuchaphazeleki kukuguquguquka koxinzelelo oluphakathi.
• Isakhiwo siyinkimbinkimbi, inkangeleko iyonke iqinile kancinci, kwaye umzimba wevalvu uhlala utyebile.
• Ifanelekile kwiinkqubo zemibhobho ezinoxinzelelo oluphezulu, ezinobukhulu obukhulu, kunye neemeko ezineemfuno eziphezulu zokusebenza kokutywina kunye nokulawula ukuhamba kwamanzi.

2. Ivalvu yebhola edadayo

• Xa uxinzelelo oluphakathi luphantsi okanye kungekho xinzelelo luphakathi, ukusebenza kokutywina kunokuchaphazeleka kwinqanaba elithile.
• Ulwakhiwo lulonke lulula, inkangeleko incinci, kwaye umthamo uhlala uncinci.
• Isetyenziswa rhoqo kwiinkqubo zemibhobho ezinoxinzelelo oluphakathi noluphantsi, ezinobubanzi obuncinci, kunye nezihlandlo ezineemfuno eziphezulu zococeko oluphakathi kunye noxinzelelo oluphakathi oluzinzileyo.

Izicelo

1. Ivalvu yebhola yeTrunnion

Ifanelekile ngakumbi kwiimeko zoxinzelelo oluphezulu, ezinkulu, njengeenkqubo eziphambili zemibhobho kwi-petrochemical, ukuhanjiswa kwegesi yendalo, umbane kunye neminye imboni.

Ifanelekile kwiziganeko ezifuna ukutywinwa ngeendlela ezimbini, kuba uyilo lwesihlalo sevalvu yevalvu yebhola esisigxina lunokuqinisekisa ukutywinwa kuzo zombini iindlela.

2. Ivalvu yebhola edadayo

Isetyenziswa kakhulu kwimizi-mveliso yeekhemikhali, ipetroliyam, igesi yendalo kunye ne-metallurgical, ingakumbi kwimibhobho yegesi yendalo ekude equlethe i-hydrogen sulfide media, ukungcola okanye ukugqwala okukhulu.

Ikwafanelekile nakwizihlandlo apho kukho iimfuno eziphezulu zococeko oluphakathi kunye noxinzelelo oluphakathi oluzinzileyo, njengeenkqubo zokuhambisa amanzi kunye nemibhobho yokuhambisa amanzi, iinkqubo zomoya opholileyo, njl.

Isishwankathelo

Iivalvu zebhola zeTrunnion kunye neevalvu zebhola ezidadayonganye inesakhiwo sayo esahlukileyo kunye neempawu zokusebenza, ezifanelekileyo kwizicelo ezahlukeneyo. Xa ukhetha, kufuneka kuqwalaselwe ngokubanzi izinto ezifana neemeko ezithile zokusebenza, iimpawu eziphakathi kunye neemfuno zokusebenza kokutywina.
