I-valve yebhola enomgodi oqinile ebholeni ibizwa ngokuthi i-Trunnion Mounted Ball Valve. I-Trunnion Mounted Ball Valve isetshenziselwa kakhulu ukucindezela okuphezulu kanye nobubanzi obukhulu. Ngokusho kokufakwa okuhlukile kwendandatho yokuvala isihlalo, i-Trunnion Mounted Ball Valve ingaba nezakhiwo ezimbili: isihlalo esivalwe phambi kwe-sphere, kanye nesihlalo esivalwe ngemuva kwe-sphere.
1. Izici ze-Trunnion Mounted Ball Valve:
1. Umsebenzi wokuvimba nokukhipha kabili: i-Trunnion Mounted Ball Valve isebenzisa isihlalo esintantayo esinomfutho wentwasahlobo, kungakhathaliseki ukuthi i-valve isesimweni esivulekile noma esivaliwe ngokuphelele, izihlalo ze-valve ezingenhla nezingezansi zivimba uketshezi, futhi i-retentate emzimbeni we-valve ikhishwa nge-valve yokukhipha.
2. Umsebenzi wokukhulula ingcindezi ozenzakalelayo: Lapho izinga lokushisa lendawo esele emgodini womzimba we-valve likhuphuka futhi libangela ukwenyuka kwengcindezi okungavamile, akudingeki lidlule ku-valve yokuphepha, kodwa umsebenzi wesihlalo se-valve unganciphisa ingcindezi ngokuzenzakalelayo, okuwukuqinisekisa ukuphepha kwe-valve lapho kuthuthwa izinto eziwuketshezi. Ucansi lubaluleke kakhulu.
3. Isakhiwo sokuphepha komlilo: Wonke ama-valve anemisebenzi yokuphepha komlilo, futhi ukwakheka kwawo kanye nokukhiqizwa kwawo kulandela izidingo ze-API 607 kanye ne-API 6FA.

2. Izinzuzo ze-Trunnion Mounted Ball Valve:
1. Ukusindisa ekufakweni kwe-grease okuphuthumayo: ngenxa yezinto zangaphandle endaweni noma emlilweni okubangela ukuthi uphawu lwesihlalo se-valve lungasebenzi ngokungazelelwe, i-grease injection valve inikeza uxhumano olusheshayo nesibhamu se-grease injection, futhi ipompo engenisiwe ingayifaka kalula futhi ngokushesha i-grease sealing engxenyeni ye-valve sealing. Ukunciphisa ukuvuza.
2. Ukuvalwa kwesiqu se-valve okuthembekile kanye ne-torque ephansi yokusebenza: Ngaphezu kwendandatho yokuvala ejwayelekile, uphawu lwe-O-ring lubekwe e-gland yokupakisha. Ukuvalwa okuphindwe kabili kuqinisekisa ukuthembeka kwe-valve stem seal; ukupakisha okwengeziwe kwe-graphite kanye ne-sealing grease Injection inciphisa ukuvuza kwesiqu se-valve ngemva komlilo. I-bearing eshelelayo yesiqu se-valve kanye ne-thrust bearing kwenza i-valve ibe lula ukuyisebenzisa.
3. Ububanzi obugcwele noma ububanzi obuncishisiwe: Ububanzi obugcwele noma isakhiwo sobubanzi obuncishisiwe singakhethwa ngokwezidingo. Umgodi wokugeleza kwevalvu egcwele ufana nobubanzi bangaphakathi bepayipi, okuyinto elula ukuhlanzwa kwepayipi.
4. Isiqu se-valve singandiswa: Ngokwezidingo zokufakwa noma ukusebenza, isiqu se-valve singandiswa. I-valve ye-stem ball ende ifaneleka kakhulu ngezikhathi lapho amapayipi kudingeka angcwatshwe phansi, njengegesi yedolobha. Ubukhulu besiqu esinde bunqunywa ngokwezidingo zamakhasimende.
5. Ukusebenza okuguquguqukayo: Isihlalo se-valve kanye ne-stem bearing enomthamo omncane wokungqubuzana kanye nempahla enhle yokuzigcoba iyasetshenziswa, okunciphisa kakhulu i-torque yokusebenza kwe-valve. Ngakho-ke, ngisho noma kungekho grisi yokuvala, i-valve ingasebenza ngokuguquguqukayo isikhathi eside.
