Umsebenzi wokutshixa ivalvu
Kwimeko yokutshixa ngaphandle, ukutshixa ngaphandle kwevalvu kunemisebenzi elandelayo:
- Ulawulo lokhuseleko:Ukutshixwa kweevalvu kunokuthintela ukusetyenziswa kweevalvu ngaphandle kwemvume okanye ngengozi, ngaloo ndlela kuthintelwe ukuvuza, umonakalo kwizixhobo, kwaneengozi zokhuseleko ezibangelwa kukuvulwa okanye ukuvalwa kweevalvu ngendlela engafanelekanga.
- Ukuthintela ukusetyenziswa gwenxa:Kwimveliso yemizi-mveliso, iivalvu kufuneka zigcinwe zilungiswe. Ukutshixwa kweevalvu kunokuzivalela iivalvu ngeli xesha leenkqubo ukuthintela iingozi ezibangelwa kukungakhathali okanye ukusebenza ngendlela engafanelekanga.
- Isiphumo sesilumkiso:Ukutshixa iivalvu kunye nokuthega kungalumkisa abanye abasebenzi ukuba baqaphele ukuba ivalvu itshixiwe kwaye ayinakusondelwa okanye isebenze ngokuthanda kwayo, kusebenza njengomsebenzi wesilumkiso.
- Ukuqinisekisa imeko yokhuseleko lwezixhobo:Ngokutshixa iivalvu, kunokuqinisekisa ukuba izixhobo zivaliwe ngokupheleleyo kwaye zihlala zikwimeko ekhuselekileyo, nto leyo ethintela ukuba izixhobo zingaqali ngengozi, nto leyo ebangela ukwenzakala okanye ukufa.
Izinto ezisetyenziswa kakhulu xa kutshixwa iivalvu kunye nezizathu zokukhethwa kwazo zezi zilandelayo:
- Inayiloni:Inokumelana okuhle neempembelelo kunye nozinzo lweekhemikhali, ayimelani nokugqwala, kwaye inokugcina ukusebenza kwayo kwiimeko ezinzima.
- Iplastiki yobunjineli be-ABS:Inamandla aphezulu, iyamelana kakuhle nempembelelo, kwaye inokubunjwa ibe ziimo ezahlukeneyo ukuze ivumelane neentlobo ezahlukeneyo zeevalvu.
- I-Polypropylene:Inokumelana kakuhle nokugqwala, ayimelani nokugqwala kweekhemikhali, kwaye iqinile kwaye ihlala ixesha elide.
- I-Polytetrafluoroethylene:Inokumelana nokugqwala okugqwesileyo kunye nokumelana nokuguguleka, kwaye idla ngokusetyenziswa njengesihlalo sevalvu okanye izinto zomphezulu wediaphragm zeevalvu.
- Intsimbi yodidi lwemizi-mveliso: Inamandla aphezulu kwaye ihlala ixesha elide, ifanelekile kwiindawo ezininzi zoshishino, kwaye inokuthintela ngempumelelo amandla angaphandle ukuba angonakalisi.
- Yenziwe ngentsimbi eshayinayo:Inokumelana nokugqwala okunamandla kwaye ifanelekile kwiindawo ezinobushushu obuphezulu, ezinomswakama ophezulu okanye kwiindawo ezine-corrosion yeekhemikhali. Umzekelo, intsimbi engagqwaliyo ye-austenitic, intsimbi engagqwali ekhethekileyo, njl.njl., zifanelekile kwiindawo ezahlukeneyo zokugqwala.
