I-valve yokuphepha yohlobo lwasentwasahlobo
| Uhlobo | Ivalvu yokuphepha |
| Imodeli | I-A68Y-P54110V, A68Y-P54140V, A68Y-P54200V, A68Y-P5432V, A68Y-P5445V, A68Y-P5464V |
| Ububanzi Okuzisholo | I-DN 40-150 |
Isebenza kusitimu, umoya nezinye izinto ezisetshenziswayo eziphakathi nendawo noma ipayipi (izinga lokushisa lokusebenza ≤560℃ kanye nengcindezi yokusebenza ≤20MPa) njengesivikelo sokucindezela ngokweqile.
- Ngomklamo wesakhiwo sokukhishwa okugcwele kwentwasahlobo, i-valve ine-coefficient enkulu yokukhipha, isakhiwo esilula, ukusebenza kahle kokuvala uphawu, ingcindezi yokuvula enembile, i-blowdown encane, ukulungiswa okulula nezinye izici.
- Isihlalo se-valve yisihlalo se-Laval nozzle valve. Uma ugeleza endaweni yokuphuma yesihlalo sevalvu, isitimu sifika kusivinini esiphezulu kanye ne-coefficient enkulu yokukhipha, ekwazi ukwehlisa inani lokufakwa kwamavalvu okuphepha kubhayela. Nge-alloy build-up welding eqinile, indawo evalekayo yesihlalo se-valve ifaka ukumelana nokuhuzuka, ukumelana nokuguguleka nempilo ende yesevisi.
- Ngesakhiwo sokunwebeka esishisayo, idiski ye-valve isebenzisa ukuguqulwa kwayo okuncane ukuze isinxephezelo ngaphansi kwamandla abambayo aphakathi nendawo ukuze ithuthukise ikhono lokuvala futhi inqobe ukukhishwa kusengaphambili kwe-valve yokuphepha lapho ingcindezi ephakathi isondela ekucindezelweni kokusetha. Ngobuchwepheshe bokucisha obuthuthukisiwe, indawo yokuvala yediski ye-valve ifaka ubulukhuni obuthuthukisiwe, ukumelana nokuhuzuka kanye nokumelana nokugqwala.
- Umthelela wendandatho engaphezulu yokulungisa ukushintsha indlela yokuhamba kwemaphakathi ukusuka esihlalweni sevalvu ukushintsha amandla abambayo aphikisayo we-medium kudiski ye-valve. Ukuma kweringi engaphezulu yokulungisa kuthinta ukwehla kwe-valve ngokuqondile.
- Isikhala se-annular sakhiwe phakathi kwephezulu kwendandatho ephansi yokulungisa kanye nendiza engezansi ye-valve disc. Ingcindezi ishintshwa ngokulawula ivolumu yesikhala seringi yokulungisa ephansi ukuze ifinyelele ukucindezela okufanele kokuvula.
- Ukucindezelwa kwentwasahlobo kulungiswa yinati elilawulayo ukwenza i-valve ithole ukucindezela okunembile kokumisa kahle futhi ngokushesha.
- Umkhono wokulungisa i-backpressure uyindlela eyisizayo yokulungisa i-valve disc backpressure. I-blowdown efanele ingatholakala ngokulungiswa komkhono wokulungisa i-backpressure; lungisa phezulu ukuze wehlise i-backpressure futhi ulungise phansi ukuze ukhuphule i-valve backpressure.
- Isixhumi sokupholisa sisethwe phakathi kwentwasahlobo kanye nomzimba we-valve ukuze kuvinjwe intwasahlobo kusukela ekuthintekeni kwesitimu sokushisa okuphezulu nokuqinisekisa ukunwebeka okuzinzile nokuqhubekayo kwentwasahlobo.
- Intwasahlobo iyingxenye ebalulekile yokunquma ukusebenza kwe-valve yokuphepha. Iziphethu ezihlukene zenzelwe izingcindezi ezihlukene zokubeka kanye nama-blowdown.
- I-isolator yokushisa ihlukanisa umzimba we-valve kusukela entwasahlobo ukunciphisa umthelela wokushisa entwasahlobo, iqinisekise ukuqina kwentwasahlobo futhi yenze ukusebenza kwentwasahlobo kuzinze.
