Ekuxhumeni kwamapayipi, amajoyinti okunweba umkhawulo we-double-flange (uhlobo lwe-VSSJA-2/B2F) kanye namajoyinti okudlulisa amandla e-double-flange (uhlobo lwe-VSSJAF/C2F) yimikhiqizo emibili evamile enemisebenzi ehlukene. Nakuba womabili asetshenziselwa ukuxhuma amapayipi ane-flange kuzo zombili izinhlangothi, ngokusobala ahlukile ngokubukeka kwawo kanye nomsebenzi oyinhloko.
Mina.Umehluko ngesakhiwo nokubukeka
1. I-Double Flange Restrained Expansion Joint (VSSJA-2/B2F)
-Izingxenye eziyinhloko:yakhiwe ngomzimba, indandatho yokuvala, i-gland kanye nokufinyeza kwe-telescopic.
-Izici zokubukeka:Kukhona ama-flange amane emzimbeni. Ubude bebholithi elilinganiselwe abudluli umkhiqizo ngokwawo, futhi isakhiwo sonke sincane kakhulu.
2.I-Double Flange Force Transfer Joint
- Izingxenye eziyinhloko:Yakhiwe ngomzimba, indandatho yokuvala, i-gland, i-flange yeshubhu emfushane, izipikili ezinde namantongomane.
-Izici zokubukeka:Kunezinhlayiya ezintathu emzimbeni. I-stud yayo yokudlulisa amandla okuxhuma ngokusobala yinde kunomzimba womkhiqizo, okuyindawo yokuhlonza eqondakala kalula.
II.Imisebenzi eyinhloko kanye nezimiso zokusebenza
1. I-flange ephindwe kabiliukuzibambaijoyinti lokunweba: isinxephezelo kanye nokuvikelwa
Umsebenzi wayo oyinhloko ukukhokhela ukwanda nokuncipha kokushisa kwamapayipi, ukumunca ukufuduka kwe-axial kanye ne-radial, nokuqinisekisa ukusebenza okuphephile kohlelo lwamapayipi ngamadivayisi anqunyelwe.
-Vumela ukwanda nokufinyela:Ngaphakathi kobubanzi obujwayelekile, ingakhula futhi inciphe ngokukhululeka ukuze ikhokhele ukufuduka kwepayipi okubangelwa ukwanda nokuncipha kokushisa.
- I-Safumkhawulo we-ety:Uma ukwanda nokuncipha kufinyelela umkhawulo, ibhawodi elinqunyelwe lizosebenza njengesithiyo somshini ukuvimbela ipayipi ukuthi lingaqhekeki noma lonakale ngenxa yokufuduka ngokweqile.
-Izimo ezisebenzayo:Ifaneleka kakhulu amapayipi anokudlidliza, ukuthambeka okuthile noma ukugoba. Ingabhekana ngempumelelo nokufuduka kwe-axial ngaphakathi kwe-engeli ethile, futhi futhi yenza kube lula ukufakwa nokugcinwa kwamavalvu namaphampu amanzi.
2. Okuphindwe kabilifi-langefibuthotukuqhumaji-oint: Ukudlulisa i-thrust kanye nokuxhumeka
Umsebenzi wayo oyinhloko ukudlulisa ukushukuma kwepayipi, ukukhokhela amaphutha okufakwa, nokuqinisekisa ukusebenza okuzinzile kwamaphampu, amavalvu kanye nezinhlelo zamaphayiphi.
-Ubude bokukhiya:Ngesikhathi sokufakwa, kuyadingeka ukulungisa ubude obudingekayo ngokwebanga langempela elibekiwe, bese ukhiya amabhawodi okudlulisa amandla ukuze umkhiqizo ugcine ubude obungaguquki ngesikhathi sokusebenza.
- Imisebenzi eyinhloko:Ngesikhathi sokusebenza, ayincikile kakhulu ekunwetshweni nasekuncipheni ukuze ikhokhele ukufuduka (inani elithile lokufuduka kuphela), kodwa isebenza njengesixhumi esiqinile sokudlulisa ngempumelelo amandla e-axial akhiqizwa yimishini ohlelweni lwamapayipi ukuze kugwenywe ukulimala kokujikijelwa okugxilile emishinini.
-Izimo ezisebenzayo:Ngokuvamile isetshenziselwa ukuxhuma amaphampu, ama-valve kanye neminye imishini kumapayipi ukuqinisekisa ukusatshalaliswa okulinganayo kwe-thrust.
III. Isiphetho
Uma ipayipi libhekene nokwelulwa nokuncipha kokushisa, ukuhlaliswa kwesisekelo, kanye nokudlidliza kwendololwane, futhi kuyadingeka ukuze kulungiswe ukufuduka nokuvimbela ukudonsa, kukhethwa amalunga okunweba umkhawulo we-flange ophindwe kabili;
Uma kuxhuma amaphampu amanzi namavalvu, kuyadingeka ukusabalalisa i-axial thrust nokuvikela umzimba oyinhloko wemishini, ngakho-ke ijoyinti yokudlulisa amandla e-flange ephindwe kabili iyathandwa.
Ohlelweni lwamapayipi, amajoyinti okunweba omkhawulo we-double flange kanye namajoyinti okudlulisa amandla e-double flange ayizesekeli ezibalulekile ezibhekene "nokuxhumana nokuvikelwa" kwamapayipi, kuyilaphoamavalvu ebhabhathane, amavalvu esango, futhiama-valve okuhlolaziyimishini eyinhloko yokulawula "ukugeleza kanye nokunqamuka" kwe-medium.
