"Indlela Yokukhetha I-Globe Valve Kahle: Umhlahlandlela Wezinhlobo Nezimo Zokusebenza"
1,Uhlolojikelele
I-globe valve iwuhlobo olusetshenziswa kakhulu lwama-valve, olusetshenziswa kakhulu ukunqamula uketshezi kumapayipi. Ukukhetha okulungile kwama-valve okuvala kuyisihluthulelo sokuqinisekisa ukusebenza okuvamile kwezinhlelo zamapayipi. Lo mhlahlandlela uzokwethula ukuthi ungayikhetha kanjani kahle i-valve yokuvala, okuhlanganisa uhlobo lwayo nesimo sohlelo lokusebenza.
2,Uhlobo lwe-valve yokuvala
1. Ihlukaniswe ngesakhiwo se-valve:
a) Iqonde ngevalvu yembulunga: Ishaneli yoketshezi iqonde phakathi, inesakhiwo esilula nokumelana nokugeleza okuphansi, okwenza isetshenziswe kabanzi.
b) I-Angle globe valve: Ishaneli yoketshezi i-engeli engu-90 degree, ithatha indawo encane futhi ifanele izimo ezinendawo elinganiselwe.
c) I-valve yeglobu yamanje eqondile: Ishaneli yoketshezi iqondile futhi inokumelana nokugeleza okuphezulu, okuyenza ifaneleke izimo ezinokuvuleka okuphansi nokuvala amaza.
2. Ihlukaniswe ngezinto ze-valve:
a) I-Carbon steel globe valve: ilungele ukusetshenziswa kwezimboni ezijwayelekile ezinemidiya efana namanzi, uwoyela, umusi, njll.
b) Ivalvu yeglobu yensimbi engagqwali: ifanele indawo enezidingo zokuhlanzeka okuphezulu, njengoketshezi olubolayo, amagesi, amakhemikhali, njll.
c) Ivalvu yeglobu enomugqa we-Fluorine: ifanele indawo enamakhemikhali abolayo, ama-asidi aqinile, ama-alkali aqinile, nezinye izinto zemidiya.
3. Kuhlukaniswa ngendlela yokushayela:
a) I-valve yokuvala i-valve: Lawula ukuvuleka nokuvala kwe-valve ngokuzungezisa isiqu se-valve, elula futhi kulula ukuyisebenzisa, ifanele ukucindezela okuphansi kanye nezicelo ze-diameter encane.
b) I-valve yeglobu kagesi: Ukulawula okuzenzakalelayo kufinyelelwa ngokushayela isiqu se-valve ukuze sijikeleze ngenjini kagesi, elungele ukucindezela okuphakathi nendawo nophezulu, ukusetshenziswa kobubanzi obukhulu.
c) I-valve yeglobu ye-pneumatic: Iqhutshwa ukucindezela komoya ukuzungeza isiqu se-valve, ifinyelela ukulawula okuzenzakalelayo, ifanele ukucindezela okuphakathi nokuphezulu, izimo ezinkulu zobubanzi.
3,Izimo zokusetshenziswa kwama-valve embulunga
1. Uhlelo lokuhlinzeka ngamanzi: lusetshenziselwa ukunqamula imithombo yamanzi, ukufeza ukuqaliswa kwesistimu, ukuvala, nokugcinwa kahle.
2. Imboni ye-Petrochemical: isetshenziselwa ukunqamula imidiya ehlukahlukene, efana nowoyela, igesi, amanzi, njll., ukuqinisekisa ukuphepha kokukhiqiza.
3. Imboni yokuphehla amandla ashisayo: isetshenziselwa ukunqamula imidiya efana namanzi ashisayo nesitimu, iqinisekisa ukusebenza ngokuphephile kwamabhayela nezinto ezishisayo.
4. Imboni yokudla neziphuzo: isetshenziselwa ukunqamula imidiya efana nokudla neziphuzo, ukuqinisekisa ukuhlanzeka kwendawo yokukhiqiza.
5. Imboni yezemithi: isetshenziselwa ukunqamula izinto ezingavuthiwe zemithi, izidakamizwa, neminye imidiya ukuze kuhlangatshezwane nezidingo eziqinile zokukhiqiza.
6. Imboni yokuvikela imvelo: isetshenziselwa ukunqamula imithombo yezindaba efana nendle nodaka, futhi kuzuzwe ukusebenza okuvamile kwezindawo zokuvikela imvelo.
4,Izinyathelo zokuphepha zokukhetha ama-valve wokuvala
1. Khetha impahla ye-valve efanele ngokwezakhiwo ze-medium (njengokugqwala, izinga lokushisa, ingcindezi, njll.).
2. Khetha imodeli yevalvu efanele ngokuya ngengcindezi yokuklama, izinga lokushisa lomklamo, nobubanzi bepayipi.
3. Cabangela imodi yokushayela ye-valve bese ukhetha ama-valve okuvala okwenziwa ngesandla, kagesi, noma omoya ngokusekelwe ezimeni zesayithi kanye nezidingo.
4. Cabangela indawo yokufaka kanye nesiqondiso se-valve ukuze uqinisekise ukusebenza kwayo okuvamile.
5. Khetha ama-valve akhiqizwa abakhiqizi abahloniphekile ukuze uqinisekise ikhwalithi kanye nesevisi yangemuva kokuthengisa yama-valve.
Ngamafuphi, ukukhethwa okulungile kwama-valve okuvala kudinga ukucatshangelwa okuphelele kwezakhiwo ze-medium, imingcele yokuklama yepayipi, kanye nezimo zohlelo lokusebenza. Ngethemba ukuthi lo mhlahlandlela uwusizo kuwe.
