Ivalvu yebhola ene-shaft esisigxina ebholeni ibizwa ngokuba yiTrunnion Mounted Ball Valve. I-Trunnion Mounted Ball Valve isetyenziselwa ikakhulu uxinzelelo oluphezulu kunye nobubanzi obukhulu. Ngokwendlela eyahlukileyo yokufaka indandatho yokutywina isihlalo, iTrunnion Mounted Ball Valve inokuba nezakhiwo ezimbini: isihlalo esivaliweyo phambi kwesphere, kunye nesihlalo esivaliweyo emva kwesphere.
1. Iimpawu zeTrunnion Mounted Ball Valve:
1. Umsebenzi wokuvala nokukhupha kabini: iTrunnion Mounted Ball Valve isebenzisa isihlalo esintantayo esifakwe i-spring pre-tensioned, nokuba ivalve ikwimeko evulekileyo ngokupheleleyo okanye evaliweyo ngokupheleleyo, izihlalo zevalve ezisezantsi neziphezulu ziyawuvala ulwelo, kwaye i-retentate emzimbeni wevalve ikhutshwa ngevalve yokukhupha.
2. Umsebenzi wokunciphisa uxinzelelo ngokuzenzekelayo: Xa ubushushu besixhobo esiseleyo emzimbeni wevalvu bunyuka kwaye bubangela ukunyuka okungaqhelekanga koxinzelelo, akufuneki ukuba budlule kwivalvu yokhuseleko, kodwa umsebenzi wesihlalo sevalvu unokunciphisa uxinzelelo ngokuzenzekelayo, oku kukuqinisekisa ukhuseleko lwevalvu xa kuthuthwa izinto ezingamanzi. Isondo sibaluleke kakhulu.
3. Ulwakhiwo lokhuseleko lomlilo: Zonke iivalvu zinemisebenzi yokhuseleko lomlilo, kwaye uyilo lwazo kunye nokuveliswa kwazo kulandela iimfuno ze-API 607 kunye ne-API 6FA.

2. Iingenelo zeTrunnion Mounted Ball Valve:
1. Ukhuseleko lokuvalela i-grease injection engxamisekileyo: ngenxa yezinto zangaphandle kwindawo okanye umlilo obangela ukuba i-valve seat seat seal ingasebenzi ngequbuliso, i-grease injection valve inika unxibelelwano olukhawulezileyo ne-grease injection gun, kwaye i-pump engenisiweyo inokufaka i-grease sealing ngokulula nangokukhawuleza kwi-valve seat sealing. Ukunciphisa ukuvuza.
2. Ukutywinwa kwesiqu sevalvu okuthembekileyo kunye ne-torque ephantsi yokusebenza: Ukongeza kwiringi yokutywina eqhelekileyo, itywina ye-O-ring ikwabekwe kwi-packing gland. Itywina ephindwe kabini iqinisekisa ukuthembeka kwetywina yesiqu sevalvu; ukupakisha okongezelelweyo kwe-graphite kunye negrisi yokutywina Injection inciphisa ukuvuza kwesiqu sevalvu emva komlilo. I-valve stem sliding bearing kunye ne-thrust bearing zenza ivalvu ibe lula ukuyisebenzisa.
3. Ububanzi obupheleleyo okanye ububanzi obuncitshisiweyo: Ububanzi obupheleleyo okanye isakhiwo sobubanzi obuncitshisiweyo sinokukhethwa ngokweemfuno. Umgodi wokuhamba kwevalvu egcweleyo uyafana nobubanzi bangaphakathi bombhobho, olungele ukucocwa kwemibhobho.
4. Isiqu sevalvu sinokwandiswa: Ngokweemfuno zokufakelwa okanye zokusebenza, isiqu sevalvu sinokwandiswa. Ivalvu yesiqu se-stem esandisiweyo ifanelekile ngokukodwa kwiimeko apho imibhobho kufuneka igqunywe emhlabeni, njengegesi yesixeko. Ubungakanani besiqu se-deleted bumiselwa ngokweemfuno zabathengi.
5. Ukusebenza okuguquguqukayo: Isihlalo sevalvu kunye ne-stem bearing enomlinganiselo omncinci wokungqubana kunye nepropati elungileyo yokuzithambisa iyasetyenziswa, nto leyo enciphisa kakhulu i-torque yokusebenza kwevalvu. Ke ngoko, nokuba akukho grisi yokuvala, ivalvu ingasetyenziswa ngokuguquguqukayo ixesha elide.
