Le khasivala i-valve hgpcvv-02-B30Ingabe i-valve yokulawula ingcindezi esetshenziswe ohlelweni lwamafutha e-EH lwezitshalo zamandla, ngomsebenzi wokulawula okuzenzakalelayo. Ingalawula i-oyili / icishwe ngokuya ngenani lokucindezela kwesethi yesethi, vikela uwoyela ukuthi ukhiphe, futhi uqinisekise ukucindezela kwamafutha aqinile kupayipi eliyinhloko. Lo mkhiqizo unezici ezilandelayo kanye nemigomo yokusebenza yokulawula ingcindezi.

Okokuqala, i-VAVPCV ye-Shut-off VALPCV-02-B30 yamukela umgomo wokulawula othomathikhi ukulawula i-oyili futhi uvale ngokususelwa kunani lokucindezela elisebenzayo. Lapho ushiya ifektri, i-valve izobhekana nokubhekelwa kwengcindezelo ukuze kuqinisekiswe ukunemba kwenani lokucindezela elisebenzayo. Lesi simiso sokuzithiba senza i-valve ikwazi ukulawula ngempumelelo ukugeleza kwamafutha ngokwesidingo.

Okwesibili, inani lokucindezela le-valve lingashintshwa ukuze lihlangabezane nezidingo zamayunithi ahlukene. Ngokuvamile, kumayunithi angama-300mw, inani elisebenzayo efektri lisethwe ku-4.5 MPA. Lapho ingcindezi kawoyela ifinyelela kunani lokucindezela kwesethi yokusetha, i-valve izovimba ngokuzenzakalelayo ukugeleza kwamafutha ku-servo valve, kufinyelelwe ukulawula uwoyela.

I-VAVPCV ye-Shut-Off VGPCV-02-B30 nayo inomsebenzi wokuvimbela uwoyela ekuthunzini. Lapho i-turbine ifakwe, uma umyalo onikezwa yi-servo Card kwi-servo valve awusethwa kabusha, amafutha azoqhubeka nokukhishwa nge-servo valve, okwenza ukwehla kwengcindezi kawoyela ngepayipi eliyinhloko. Kodwa-ke, ukwakheka kwe-valpcvvvvvv-02-02-B30 kungavimba ngempumelelo ukuvela kwesimo esingenhla. Ingavimba ngokuzenzakalelayo isigaba samafutha, igcine ingcindezi eqinile kawoyela ngepayipi eliyinhloko, futhi iqinisekise ukusebenza okujwayelekile kohlelo.

Ngamafuphi, i-valpcvvvvvv-02-B30 ilungisa ingcindezi ngokubeka inani lokucindezela elisebenzayo. Yenza ukushintshwa kwengcindezi emzimbeni we-valve efektri ukuze kuqinisekiswe ukunemba kwenani lokucindezela kwesenzo. Ngokushintsha inani lokucindezela kwesenzo, isikhathi sokuvula noma sokuvala noma sokuvala se-valve singashintshwa, ngaleyo ndlela silawule phezu kwamafutha. Lapho ingcindezi kawoyela ifinyelela inani lokucindezela kwesethi yesethi, i-valve izovala ngokuzenzakalelayo, ivimbele ukugeleza kwamafutha ku-servo valve, ifinyelele umthetho oqondile wokucindezela. I-shut-off valve hgpcv-02-B30 idlala indima ebalulekile ohlelweni lwamafutha e-EH lwezitshalo zamandla, iqinisekisa ukusebenza okuphephile nokuzinzile kohlelo.
