Q: yiziphi izici okufanele zinakwe lapho kufakwa, ukusetshenziswa nokugcinwa kwe-valve yokuphepha?

A:

Izici ezidinga ukunakwa ekufakweni, ukusetshenziswa nokugcinwa kwama-valve okuphepha

Ukusebenza okulungile kwe-valve yokuphepha kubaluleke kakhulu, ngakho-ke yiziphi izici okufanele zinakwe lapho kufakwa, ukusetshenziswa nokugcinwa kwe-valve yokuphepha?

Ikhwalithi ye-valve yokuphepha ngokwayo iyisidingo sokuqinisekisa ukusebenza okuphephile nokuzinzile.Kodwa-ke, uma umsebenzisi engayisebenzisi kahle, i-valve yokuphepha ingase ingasebenzi ngokujwayelekile, ngakho ukufakwa nokusetshenziswa kubaluleke kakhulu.Phakathi kwezinkinga ezibikwe ngabasebenzisi, ukwehluleka kwe-valve yokuphepha okubangelwa ukufakwa okungalungile nokusetshenziswa kwe-akhawunti ye-80%.Lokhu kudinga abasebenzisi ukuthi bathuthukise ukuqonda kwabo kolwazi lomkhiqizo we-valve yokuphepha kanye nobuchwepheshe futhi balandele ngokuqinile imininingwane yokusebenza.

Amavalvu okuphepha angamathuluzi emishini anembayo futhi anezidingo eziphakeme uma kuqhathaniswa zokufakwa nokusetshenziswa kwawo.Ezimbonini zezinqubo eziqhubekayo, ngemva kokwakhiwa kwesethi yemishini, izodlula ezinqubweni ezimbalwa ezifana nokuhlanzwa, ukucinana komoya, nokuhlolwa kwengcindezi, bese iqala ukusebenza.Iphutha elivamile elenziwa abasebenzisi ukufaka i-valve yokuphepha epayipini lenqubo ngesikhathi sokuhlanza.Njengoba i-valve yokuphepha isesimweni esivaliwe, imfucumfucu ingena endaweni yokungena ye-valve yokuphepha ngesikhathi sokuhlanza.Ngesikhathi sokuhlolwa kwengcindezi, i-valve yokuphepha iyagxuma futhi ibuye.Ngenxa yemfucumfucu lapho uhlezi, i-valve yokuphepha izohluleka.

Ngokwamazinga kazwelonke, lezi zinyathelo ezilandelayo kufanele zithathwe lapho kuhlanzwa:

1. Ivalvu yokuphepha ivunyelwe ukufakwa epayipini lenqubo, kodwa ipuleti eliyimpumputhe kufanele lifakwe endaweni yokungena yevalvu yokuphepha ukuze livalwe.
2. Ngaphandle kokufaka i-valve yokuphepha, sebenzisa ipuleti eliyimpumputhe ukuze uvale ukuxhumana phakathi kwevalvu yokuphepha nepayipi lenqubo, futhi ufake kabusha ivalvu yokuphepha ngemva kokuqedwa kokuhlolwa kwengcindezi.
3. I-valve yokuphepha ikhiyiwe, kodwa kunengozi kulesi silinganiso.Umsebenzisi angase akhohlwe ukuyisusa ngenxa yobudedengu, okwenza ivalvu yokuphepha ihluleke ukusebenza kahle.

Umsebenzi wenqubo kumele uzinze ngesikhathi sokusetshenziswa.Uma ukushintshashintsha kwengcindezi kukukhulu, kuzodala ukuthi i-valve yokuphepha igxume.Ngokwezindinganiso zikazwelonke, uma i-valve yokuphepha igxuma, kufanele ilinganiswe kabusha.

Ngaphezu kwalokho, imingcele yezobuchwepheshe enikezwe umsebenzisi kufanele inembile, futhi i-medium yesicelo kufanele ilungiswe.Isibonelo, i-medium emingceleni yezobuchwepheshe enikeziwe ingumoya, kodwa uma i-chlorine ixubene nayo ngesikhathi sokusetshenziswa, i-chlorine ne-vapor yamanzi izohlangana ukuze yenze i-hydrochloric acid, ezolimaza i-valve yokuphepha.Ibangela ukugqwala;noma i-medium kumapharamitha wezobuchwepheshe anikeziwe amanzi, kodwa i-medium yangempela iqukethe i-gravel, ezokwenza ukuthi i-valve yokuphepha iguge.Ngakho-ke, abasebenzisi abakwazi ukushintsha imingcele yenqubo ngokuthanda kwabo.Uma izinguquko zidingeka, kufanele bahlole ukuthi i-valve yokuphepha ehlinzekwa umenzi we-valve ifanele izimo zokusebenza ezishintshile futhi ixhumane nomkhiqizi ngesikhathi esifanele.

Uma okungenhla kungasetshenziswa ngendlela efanele ngokuhambisana nezicaciso ezijwayelekile, ivalvu yokuphepha kufanele ihlolwe minyaka yonke, futhi umqhubi kufanele athole “Isitifiketi Somqhubi Wezinto Ezikhethekile.”
