4.Ukwakhiwa ebusika, ukuhlolwa kwengcindezi yamanzi ekushiseni kwe-sub-zero.

Umphumela: Ngenxa yokuthi izinga lokushisa lingaphansi kweziro, ipayipi lizobanda ngokushesha ngesikhathi sokuhlolwa kwe-hydraulic, okungase kubangele ukuthi ipayipi liqandwe futhi liqhekeke.

Izinyathelo: Zama ukuhlola umfutho wamanzi ngaphambi kokwakhiwa ebusika, futhi ukhiphe amanzi epayipini nevalvu ngemva kokuhlolwa kwengcindezi, ngaphandle kwalokho i-valve ingase igle, futhi okubi kungase kuholele ekuqhekekeni okubandayo.

I-5.I-flange ne-gasket yokuxhumeka kwepayipi ayinamandla ngokwanele, futhi ama-bolts okuxhuma afushane noma amancane ububanzi.Iphedi yerabha isetshenziselwa ukushisa ipayipi, i-double pad noma i-inclined pad isetshenziselwa ipayipi lamanzi abandayo, futhi i-flange pad igqekeza epayipi.

Imiphumela: I-flange joint ayiqinile, noma ilimele, isenzakalo sokuvuza.I-gasket ye-flange ephumela epayipini izokwandisa ukumelana nokugeleza.

Izinyathelo: Amapayipi amapayipi kanye nama-gaskets kufanele ahlangabezane nezidingo zokucindezela kokusebenza komklamo wamapayipi.

Amaphayiphi e-flange okushisa namapayipi okuhambisa amanzi ashisayo kufanele kube ama-gasket e-asbestos enjoloba;I-gasket ye-flange yepayipi yamanzi kanye nepayipi lokudonsa kufanele kube i-rubber gasket.

I-liner ye-flange akufanele iqhume ku-tube, futhi umbuthano wangaphandle kufanele uzungezwe emgodini we-bolt we-flange.Awekho iphedi ethambekele noma ama-gaskets amaningana azofakwa phakathi kwe-flange.Ububanzi bebhawodi elixhuma i-flange kufanele libe ngaphansi kuka-2mm uma kuqhathaniswa nokuvuleka kwe-flange.Ubude bentongomane ephumayo yenduku yebhawodi kufanele bube yi-1/2 yobukhulu bentongomane.

6.Indle, amanzi emvula, amapayipi e-condensate awakwenzi ukuhlolwa kwamanzi avaliwe azofihlwa.

Imiphumela: Ingase ivuze, futhi ibangele ukulahlekelwa komsebenzisi.Ukunakekela kunzima.

Izinyathelo: Ukuhlolwa kwamanzi avaliwe kufanele kuhlolwe futhi kwamukelwe ngokuqinile ngokuya ngemininingwane.Kungcwatshwe ngaphansi komhlaba, ophahleni, phakathi kwamapayipi nezinye indle ezifihliwe, amanzi emvula, amapayipi e-condensate, njll., ukuqinisekisa ukuthi akukho ukuvuza.

7. Ukuvula nokuvala kwe-valve ngesandla, amandla amakhulu
Imiphumela: ukulimala kwe-valve elula, esindayo kuzoholela ezingozini zokuphepha

Izinyathelo:

Isondo lesandla noma isibambo se-valve yezandla iklanywe ngokuhambisana nabasebenzi abavamile, kucatshangelwa amandla okubekwa uphawu kanye namandla okuvala adingekayo.Ngakho-ke awukwazi ukusebenzisa izinsimbi ezinde noma izandla ezinde ukuhambisa ibhodi.Labo abajwayele ukusebenzisa ama-wrenches kufanele banake kakhulu ukuthi bangasebenzisi amandla amaningi, ngaphandle kwalokho kulula ukulimaza indawo yokuvala, noma ukuphula isondo lesandla nesibambo.Vula futhi uvale i-valve, amandla kufanele abe bushelelezi, angabi nomthelela onamandla.Ukuze i-valve ye-steam, ngaphambi kokuvula, kufanele ishiswe kusengaphambili, futhi i-condensate kufanele ikhishwe, futhi lapho ivula, kufanele ihambe kancane ngangokunokwenzeka ukuze igweme ukwenzeka kwesando samanzi.

Lapho i-valve ivuliwe ngokugcwele, i-handwheel kufanele iguqulwe kancane, ukuze intambo phakathi kwe-tight, ukuze ingakhululeki umonakalo.Kumavalvu esiqu esivulekile, khumbula ukuma kwesiqu lapho sivuleke ngokugcwele futhi sivaleke ngokugcwele ukuze ugweme ukushaya isikhungo esingaphezulu esifile lapho sivuleke ngokugcwele.Futhi kulula ukuhlola ukuthi ukuvalwa okugcwele kujwayelekile yini.Uma i-disc iwa, noma imfucumfucu enkulu ishumekwe phakathi kwe-spool seal, indawo ye-valve stem kufanele ishintshwe lapho i-valve ivaliwe ngokugcwele.

Lapho ipayipi liqala ukusetshenziswa, kukhona ukungcola okwengeziwe kwangaphakathi, i-valve ingavulwa kancane, ukugeleza kwesivinini esikhulu se-medium kungasetshenziswa ukuyigeza, bese ivalwa kahle (ayikwazi ukuvaleka ngokushesha, ukuvimbela insalela). ukungcola ekulimazeni indawo yokuvala), bese ivulwa futhi, iphindwe izikhathi eziningi, ikhipha ukungcola, bese ifakwa emsebenzini ojwayelekile.Ngokuvamile vula i-valve, indawo yokuvala ingase inamathele ngokungcola, futhi kufanele igezwe ihlanzeke ngale ndlela engenhla lapho ivaliwe, bese ivalwa ngokusemthethweni.

Uma isondo lesandla noma isibambo sonakalisiwe noma silahlekile, kufanele sifaniswe ngokushesha, futhi asikwazi ukushintshwa ngesandla sepuleti esiguquguqukayo, ukuze kugwenywe ukulimala kwesiqu se-valve nokwehluleka ukuvula nokuvala, okuholela ezingozini ekukhiqizeni.Eminye imidiya, ngemuva kokuthi i-valve ivaliwe ukuze ipholile, ukuze izingxenye ze-valve zinciphe, opharetha kufanele aphinde avalwe ngesikhathi esifanele, ukuze indawo yokuvala ingashiyi i-seam emihle, ngaphandle kwalokho, okuphakathi okuvela ekugelezeni kwe-seam emihle. ngesivinini esikhulu, kulula ukucekela phansi indawo yokuvala.

Uma uthola ukuthi ukuhlinza kunzima kakhulu, hlaziya imbangela.Uma ukupakisha kuqinile kakhulu, kungakhululeka kahle, njenge-valve stem skew, kufanele yazise abasebenzi ukuthi balungise.Amanye ama-valve, esimweni esivaliwe, ingxenye yokuvala inwetshwa ukushisa, okuholela ebunzimeni ekuvuleni;Uma kufanele ivulwe ngalesi sikhathi, ungakwazi ukukhulula intambo yekhava ye-valve isigamu ukuphenduka kwelinye ithuba, susa ukucindezeleka kwesiqu, bese udonsa isondo lesandla.
