Uhlobo lwentwasahlobo lokuphepha
| Thayipha | Ukuphepha Valve |
| Imodeli | I-A68Y-P54110V, A68Y-P54140V, A68Y-P54200V, A68Y-P5432V, A68Y-P5445V, A68Y-P5464V |

Isebenza kumusi, umoya nezinye izinto zokusebenza eziphakathi nendawo noma ipayipi (izinga lokushisa elisebenzayo ≤560 ℃ nokucindezela okusebenzayo ≤20MPa) njengesivikeli sokucindezelwa ngokweqile.
- Ngomklamo wokwakheka kwentwasahlobo ogcwele, i-valve inesilinganiso esikhulu sokukhipha, isakhiwo esilula, ukusebenza kahle kokufaka uphawu, ingcindezi yokuvula enembile, ukuqhuma okuncane, ukulungiswa okulula nezinye izici.
- Isihlalo valve kuyinto Laval umlomo wombhobho valve esihlalweni. Lapho ugeleza endaweni yokuphuma esihlalweni se-valve, umusi ufinyelela isivinini esikhulu kakhulu kanye ne-coefficient enkulu yokukhipha, ekwazi ukunciphisa inani lokufakwa kwamavalvu okuphepha kubhayela. Nge-welding eqinile yokwakha-up, indawo yokufaka uphawu esihlalweni se-valve ifaka ukumelana nokuhuzuka, ukumelana nokuguguleka kanye nempilo ende yokusebenza.
- Ngesakhiwo sokunwebeka esishisayo, idiski ye-valve isebenzisa ukushiyeka kwayo okuncane ukunxephezelwa ngaphansi kwamandla asebenzayo aphakathi nendawo ukwenza ngcono ukubekwa uphawu kwamandla futhi kunqobe ukukhishwa kusengaphambili kwe-valve yokuphepha lapho ingcindezi ephakathi isondela ekucindezelweni kokusetha. Ngobuchwepheshe bokucima obuthuthukile, indawo yokufaka uphawu yediski ye-valve ifaka ubulukhuni obuthuthukisiwe, ukumelana nomhuzuko nokumelana nokugqwala.
- Umphumela wendandatho yokulungisa ephezulu ukuguqula ukugeleza kokuhamba kokuphakathi ukusuka esihlalweni se-valve ukushintsha amandla asebenzayo aphikisayo aphakathi nendawo ku-valve disc. Ukuma kweringi yokulungisa ephezulu kuthinta ukwehla kwe-valve ngqo.
- Kwakhiwa isikhala esiyiminyaka ephakathi kwaphezulu kwendandatho yokulungisa engezansi nendiza engezansi yediski ye-valve. Ingcindezi iyashintshwa ngokulawula ivolumu yesikhala sendandatho ephansi yokulungisa ukuze ifinyelele ingcindezi efanele yokuvula.
- Ukuminyaniswa kwentwasahlobo kulungiswa yinati elawulayo ukwenza i-valve ithole ukucindezelwa okunembile kokusetha kahle futhi ngokushesha.
- Umkhono wokulungisa i-backpressure uyindlela esizayo yokulungisa ukucindezelwa kwe-valve disc. Ukuhlakazeka okufanele kungatholakala ngokulungiswa komkhono wokulungisa ingcindezi emuva; lungisa phezulu ukunciphisa ukuncipha kokubuyela emuva futhi ulungise phansi ukwandisa i-valve backpressure.
- Isixhumi sokupholisa sisethwe phakathi kwentwasahlobo nomzimba we-valve ukuvikela intwasahlobo kumthelela wokushisa okuphezulu futhi kuqinisekise ukuqina okuzinzile nokuhlala njalo kwentwasahlobo.
- Intwasahlobo yingxenye ebalulekile enquma ukusebenza kwe-valve yokuphepha. Iziphethu ezahlukahlukene zenzelwe izingcindezi ezahlukahlukene zokusetha kanye ne-blowdown.
- Isihlukanisi sokushisa sihlukanisa umzimba we-valve entwasahlobo ukunciphisa umthelela wokushisa entwasahlobo, kuqinisekiswe ukuqina kwentwasahlobo nokwenza ukusebenza kwesiphethu sentwasahlobo.
