I-American Standard WeldingI-Plug ValveIncazelo emfushane:
I-valve yepulaki inesakhiwo esilula, ukushintshwa okusheshayo, ukumelana noketshezi oluncane, kanye nokusebenza kwe-angular stroke okusheshayo.Esimeni esiphuthumayo njengengozi, ipayipi lingaxhunywa ngokushesha noma linqanyulwe.Uma kuqhathaniswa nama-valve esango nama-valve embulunga, ukusebenza kuvumelana nezimo futhi ukushintshwa kuyashesha.I-valve yepulaki isebenzisa umzimba wepulaki onembobo ephumela njengelungu elivulayo nelivalayo, futhi umzimba wepulaki uzungeza nesiqu se-valve ukuze ubone isenzo sokuvula nokuvala.
Ibanga lesicelo se-valve yepulaki eshiselwe i-American standard:
Ivalvu yokushisela yesokhethi yaseMelika esezingeni elifanele ifanele amapayipi okucindezela okuzisholo okuthi CLASS150~CLASS600LB, izinga lokushisa elisebenzayo elingu -29°C~180°C likaphethiloli, amakhemikhali, ezekhemisi, umanyolo, imboni yamandla kagesi, njll. Imidiya yepayipi.
Izici zesakhiwo se-valve ye-plug ye-Welded ejwayelekile yaseMelika:
1. Umkhiqizo unesakhiwo esinengqondo, ukubekwa uphawu okuthembekile, ukusebenza okuhle kakhulu nokubukeka okuhle.
2, ukuvalwa kwe-socket welding plug valve kufinyelelwa ngokuvala indawo ezungeze i-ferrule.Isithako esiyingqayizivele esingu-360° sokuvikela izindebe zensimbi.
3. I-valve ayinakho umgodi wokuqongelela okuphakathi.
I-4, udebe lwensimbi luhlinzeka ngomphumela wokuzihlanza lapho iqhude liphendukile, lilungele ukukala kwe-viscous nokulula.
5, ukugeleza kwezindlela ezimbili, kulula ukuyisebenzisa nokufaka.
6. Izinto ezibonakalayo kanye nosayizi we-flange wezingxenye zingamataniswa ngokunengqondo ngokuvumelana nezimo zangempela zokusebenza noma izidingo zomsebenzisi ukuze kuhlangatshezwane nezidingo ezihlukahlukene zobunjiniyela.

Imiyalo yokufakwa kwe-valve yepulaki eshiselwe ejwayelekile yaseMelika:
1. Shiya indawo lapho isiqu se-valve sizungeza.
2. Ayikwazi ukusetshenziselwa ukupholisa.
3. I-valve yebhola enomshini wokudlulisela kufanele ifakwe iqonde.
