- Umkhiqizi we-ARAN we-Trunnion Ball Valves uyatholakala ngemiklamo ehlukahlukene, izinto zokwakha, osayizi namakilasi okucindezela futhi ahambisana ngokugcwele namazinga okukhiqiza amazwe ngamazwe ANSI, ASME B16.34, API 6D, ISO17292, GOST, DIN/EN imininingwane njll.
- I-valve yebhola ye-Trunnion inobubanzi obukhulu bokukhiqiza I-Class 150 ~ I-Class 2500, i-PN16 ~ PN420, izinto ezahlukene zisetshenziselwa ukuthutha izimboni zamanzi / umusi / uwoyela negesi, kungaba izinga lokushisa eliphansi kanye nezimo zokufaka umfutho ophezulu, imikhiqizo efanelekile efana ne-nitric acid, i-acetic acid, imidiya ye-oxidizing, urea, njll.
- Ama-valve ebhola e-trunnion asetshenziswa kakhulu ekucwengisweni kwe-petroleum, amapayipi amabanga amade, imboni yamakhemikhali, ukwenza iphepha, imithi, ukongiwa kwamanzi, amandla kagesi, ukuphathwa kukamasipala, insimbi neminye imikhakha njll.
Iyini incazelo yevalvu yebhola ye-Trunnion?
- Ivalvu yebhola ye-trunnion iyi-valve ephenduka ikota futhi idizayini ye-trunnion isho ukuthi ukuhlangana kwebhola kusekelwa i-trunnion esekelayo ephansi kanye nesiqu esiphezulu esingaphezulu ekamelweni le-valve yebhola.Lo mklamo ubizwa ngokuthi i-trunnion mounted ball valve noma i-trunnion ball valve.
- I-valve yebhola ye-trunnion ngokuvamile isetshenziselwa usayizi omkhulu kanye nokusebenza kwe-valve ye-pressure ephakeme, kanye nokunciphisa i-torque ye-valve ukuze isebenze kalula.
- Isiqu esifakwe ku-trunnion simunca ingcindezi yomugqa, sivimbele ukungqubuzana okweqile phakathi kwebhola nezihlalo, ngakho-ke i-torque esebenzayo yevalvu ihlala iphansi ngomfutho ogcwele wokusebenza.
- Isihlalo se-valve ye-trunnion sivala kanjani?
- Ukuvalwa kufinyelelwa ngezihlalo zohlobo lwepiston ezilayishwe intwasahlobo ezivala ukugeleza lapho ukucindezela komugqa kusebenza esihlalweni esikhuphuka nomfula.Ukukhululeka okuzenzakalelayo komgodi phezu kwengcindezi kuqinisekiswa ngenxa yedizayini ye-trunnion uma kwenzeka izihlalo ezizikhululayo .Ibhola lisebenza ngokuphotha okuvalekile lapho opharetha exhunywe khona.Amavalvu ebhola enzelwe ukuthi asetshenziswe njengamathuluzi okulawula ukugeleza avuliwe/avaliwe futhi akufanele asetshenziselwe ukumpintsha ukugeleza koketshezi.Ama-valve kufanele ahlale evulekile noma evaliwe.
- Idizayini yezihlalo ze-valve ye-Trunnion inezici ezibalulekile zokuklama zezidingo ezahlukahlukene zohlelo lokusebenza:
- ● IZIHLALO EZIZIPHUMULAYO /IZIHLALO ZOKUPHUMULA EZINGAZODWA(SPE) kanye ne-DOUBLE PISTON EFFECT SEATS (DEP)
- ● Idizayini yezihlalo ze-DBB ne-DIB
- Ibhola levalvu ye-trunnion ligxilile kodwa izihlalo ziyagobeka.Isihlalo sine-SELF REELIEVING SEATS/SINGLE RELIEF SEATS (SPE) kanye ne-DOUBLE PISTON EFFECT SEATS (DEP) design.Idizayini ye-SPE iyindlela eyodwa yokuvalwa kwe-uni-directional futhi i-DEP iyi-bi-direction sealing, nge-API 6D/ISO 14313 echaza.
- I-ARAN isebenzisa ivalve yebhola ye-trunnion eklame izihlalo zesihlalo sosizo esisodwa i-SPE-SPE kanye nebhulokhi eliphindwe kabili futhi yopha i-DBB njengomkhiqizo ojwayelekile.Kodwa ezinye izinhlobo izihlalo design iyatholakala phezu isicelo esithile.
- Izici ze-Single Piston Effect Seat Seat Design
- Izihlalo zamavalvu ebhola zicindezelwa ebholeni ngomthwalo wasentwasahlobo.
- Njengoba umfutho womgodi womzimba ukhuphuka kunomthwalo wentwasahlobo, izihlalo zihlehliswa emuva futhi ukucindezela kukhishwa emgqeni.Lokhu kubizwa ngokuthi i-single-piston effect (ingcindezi engaphakathi komzimba iyona kuphela ipharamitha esebenzayo) .Ukukhululeka kwembobo ohlangothini olungezansi komfula, uma zombili izihlalo zamavalvu ebhola ziwumklamo womphumela we-single-piston.Isihlalo ngasinye sizikhulula ngokwaso imbobo yomzimba phezu kwengcindezi eya kulayini.
- Umfanekiso : I-Single Piston effect Seat Design
- Izici ze-Double Piston Effect Seat Design
- Kulo mklamo wesihlalo, ukucindezela okuphakathi nendawo, kanye nomfutho womgodi womzimba, kudala ukusunduza okuphusha amaringi esihlalo ebholeni.Lokhu kubizwa ngokuthi i-double piston effect (ingcindezi epayipini kanye nokuthi emzimbeni womabili amapharamitha asebenzayo).Ama-Ball Valves analo mklamo adinga idivayisi yokukhulula i-cavity pressure ukunciphisa ukucindezela kwe-cavity yomzimba.
- Umfanekiso : I-Double Piston Effect Seat Design
- I-Trunnion Ball valve i-DBB nencazelo yezihlalo ze-DIB
- ● I-valve yebhola ye-DBB (ibhulokhi ephindwe kabili ne-valve yebhola elopha)
- Ama-valve ebhola e-DBB abe yi-valve eyodwa enezihlalo ezimbili ezingaqondile.Leli bhulokhi eliphindwe kabili kanye nevalve yokopha ivala izingcindezi ezivela ezinhlangothini zombili zevalvu.Le valve ayinikezi ukuhlukaniswa okuhle kabili lapho uhlangothi olulodwa kuphela lungaphansi kwengcindezi.
- Ivalvu yebhola ye-DBB ingabhekwa njengevalvu enezihlalo ezimbili ze-piston effect (SPE) ezimbili.
- ● I-valve yebhola ye-DIB (ukuhlukaniswa kabili kanye ne-valve yebhola yokopha)
- I-DIB ball valve iyivalvu eyodwa eyodwa enezihlalo ezimbili eziqondiswe kabili.Le valve yokuhlukanisa futhi yokopha ihlinzeka ngophawu olungeziwe ngokumelene nokucindezela okuvela ohlangothini olulodwa kuphela. Lesi sici se-DIB singanikezwa ohlangothini olulodwa noma kuzo zombili izinkomba.I-valve ihlinzeka ngokuhlukaniswa okuphindwe kabili ekucindezelweni kuzo zombili iziphetho ze-valve kodwa ayikwazi ukukhulula ukucindezela komzimba okudlula izihlalo.
- Isici se-DIB singanikezwa ohlangothini olulodwa noma zombili izinkomba.
- Ivalvu enezihlalo ezimbili ze-double piston effect (DPE) inomklamo wokuhlukaniswa kabili kanye ne-bleed (DIB-1).Ivalvu enesihlalo esisodwa se-SPE nesinye isihlalo se-DPE ivalvu yokuklama i-DIB-2.I-valve ye-DIB-2 izoba nendlela yokufaka ekhethwayo.
