I-Slab Gate Valve
Incazelo Yomkhiqizo
Lo mkhiqizo owuchungechunge wamukela isakhiwo esisha sokubeka uphawu esintantayo, sisebenza ekucindezelweni akusikho ngaphezu kwe-15.0 MPa, izinga lokushisa - 29 ~ 121 ℃ epayipini likawoyela negesi, njengokulawula ukuvulwa nokuvalwa kwedivaysi ephakathi kanye nokulungisa, ukwakheka kwesakhiwo somkhiqizo. , khetha izinto ezifanele, ukuhlolwa okuqinile, ukusebenza okulula, ukunqanda ukugqwala okuqinile, ukumelana nokuguga, ukumelana nokuguguleka, Kuyimishini emisha efanelekile embonini ye-petroleum.
1. Yamukela isihlalo se-valve esintantayo, ukuvulwa nokuvala okunezindlela ezimbili, ukubekwa uphawu okuthembekile, ukuvulwa nokuvala okuvumelana nezimo.
2. Isango linesigaqo esinikeza isiqondiso esinembile, futhi indawo yokuvala ifafazwa nge-carbide, ekwazi ukumelana nokuguguleka.
3. Umthamo wokuthwala womzimba we-valve uphakeme, futhi isiteshi siqondile. Uma ivuliwe ngokugcwele, ifana nembobo yomhlahlandlela wesango kanye nepayipi eqondile, futhi ukumelana nokugeleza kuncane.I-valve stem ithatha ukupakisha okuhlanganisiwe, ukufakwa uphawu okuningi, kwenza ukubekwa uphawu kuthembeke, ukungqubuzana kuncane.
4. Lapho uvala i-valve, jikisa isondo lesandla ngokwewashi, futhi isango liyehla liye phansi. Ngenxa yesenzo sokucindezela okuphakathi, isihlalo sophawu ekugcineni kwe-inlet siphushwa esangweni, sakha ukucindezela okukhulu okuvala uphawu, ngaleyo ndlela kwakha uphawu.Ngaso leso sikhathi, inqama icindezelwa esihlalweni sokuvala ekugcineni kokuphuma. ukuze abe uphawu oluphindwe kabili.
5. Ngenxa yophawu oluphindwe kabili, izingxenye ezisengozini zingashintshwa ngaphandle kokuphazamisa umsebenzi wepayipi.Lesi isici esibalulekile sokuthi imikhiqizo yethu ize kuqala kunemikhiqizo efanayo ekhaya naphesheya.
6. Lapho uvula isango, zungeza isondo lesandla ngokuphambene newashi, isango liya phezulu, futhi imbobo yokuqondisa ixhunywe nembobo yesiteshi.Ngokuphakama kwesango, imbobo yokudlula iyanda kancane kancane. Uma ifika endaweni elinganiselwe, imbobo yomhlahlandlela iqondana nembobo yesiteshi, futhi ivuleke ngokugcwele ngalesi sikhathi.
