In the workshop Jinbin, inani elikhuluama-valve embulungazihlolwa okokugcina. Ngokwezidingo zamakhasimende, osayizi bawo basukela ku-DN25 kuye ku-DN200. (2 Inch globe valve)

Njenge-valve evamile, i-valve yembulunga ngokuyinhloko inezici ezilandelayo:

1.Ukusebenza okuhle kakhulu kokuvala: Isakhiwo sokuvala isisekelo sihlanganisa ukuhlangana okuqinile phakathi kwediski ye-valve nesihlalo se-valve. Uma ivaliwe, i-valve disc icindezela isihlalo se-valve ngaphansi kwengcindezi, ifinyelela ukusika okuqinile. Ilungele izinhlelo zokusebenza lapho ukuvuza okuphakathi kudinga ukuvinjelwa (njengamapayipi egesi nesimusi).

I-2.Ukusebenza kokulawula okuvelele: I-disc ye-valve iphakama futhi iwele eduze kwe-axis ye-valve stem, futhi izinga lokugeleza lingalungiswa ngokunembile ngokulawula izinga lokuvula. Izinga lokugeleza lishintsha ngokushelelayo lisuka ekuvulekeni ngokuphelele liye ekuvaleni ngokugcwele, okulenza lifaneleke izimo ezidinga ukulawulwa kokugeleza okuhle (njengokulungiswa kwezinga lokushisa kumasistimu okushisa).

I-3.Ukumelana nokugeleza okukhulu: I-medium idinga ukujika futhi iphume ngemva kokudlula esihlalweni se-valve, ngendlela ehlukumezayo. Ukulahlekelwa kwengcindezi kukhulu kunaleyo yama-valve aqondile njengama-valve esango. Ngakho-ke, ayilungele amapayipi anogeleza okukhulu kanye nezidingo eziphansi zokumelana (njengepayipi elikhulu lokuhlinzeka ngamanzi).

I-4.Ukufakwa kwe-Directional: Kumelwe kufakwe ngokuhambisana nesimiso esithi "low in, high out" (i-medium igeleza isuka ngaphansi kwe-valve disc), iqinisekisa ukuthi i-valve disc isiza ekufakweni uphawu ngokucindezela okuphakathi lapho ivaliwe, futhi ukusebenza akulula. Ukuyifaka ngokuhlehla kuzoholela ekwehlulekeni kophawu nokusebenza kanzima.

5.Uhlu olubanzi lwemidiya esebenzayo: Ingasetshenziselwa imidiya ehlanzekile njengamanzi, isitimu, imikhiqizo kawoyela, negesi, kodwa ayifaneleki i-high-viscosity noma imidiya ye-granular (njengoba ingagqoka kalula indawo yokuvala futhi ilimaze ukusebenza kokuvala).

Ngokusekelwe kulezi zici, ama-valve okumisa asetshenziswa kakhulu ezimeni ezidinga ukuvalwa okuqinile kanye nokulawulwa okunembile:

1. Isistimu yokuphakelwa kwamanzi kanye nokukhipha amanzi: Njengevalvu yokulawula imbulunga yamapayipi egatsha, inqamula noma ilawule umthamo wamanzi ukuze kuqinisekiswe ukulawulwa kwendawo yonke yenethiwekhi yamapayipi.

2. Isistimu yesitimu: Nqamula ukunikezwa kwesitimu noma ulawule izinga lokugeleza kwamapayipi omusi wezimboni, futhi usebenzise indawo yawo yokuvala ukuze uvimbele ukuvuza kwesitimu nokulahlekelwa amandla.

3. Imboni ye-Petrochemical: Lapho uthutha uwoyela ongahluziwe, izincibilikisi nezinye imidiya, izinga lokugeleza lilawulwa ngokulungisa izinga lokuvula ukuze lihlangabezane nezidingo zokudla zedivayisi yokusabela.

4. Amasistimu okushisa nomoya: Lawula ukugeleza kwamanzi ashisayo noma isiqandisi ukuze uzuze ukulawula okunembile kwezinga lokushisa legumbi futhi uthuthukise ukusebenza kahle kokusetshenziswa kwamandla.

Igesi kanye namapayipi omoya acindezelwe: Njengevalvu yokuvala ukuphepha, ivala ngokushesha ngesikhathi sokulungiswa noma amaphutha ukuvimbela ukuvuza okuphakathi kanye nezingozi zokuphepha ezingaba khona.

Ngezinzuzo zokubekwa uphawu okuthembekile kanye nokulawula okuguquguqukayo, i-valve yembulunga flanged isiyingxenye eyinhloko ezinhlelweni zamapayipi ahlanganisa imisebenzi yokusika nokulawula. Ayinakushintsheka ikakhulukazi ezimeni ezinobubanzi obumaphakathi namancane kanye nezidingo eziphakeme zokuvala nokulawulwa.(Intengo Yevalve Yembulunga yonke)
