Ama-valve e-globe ngokuvamile asetshenziswa njengama-valve okulawula lapho ukugoqa noma inhlanganisela yokudonsa nokuvala kudingekile. Asetshenziswa kakhulu ezinhlelweni eziningi zamapayipi, okuhlanganisa lawo amanzi, i-petroleum, amakhemikhali, ukudla, imithi, amandla, i-maritime, i-metallurgy, nezinhlelo zamandla, phakathi kokunye.
I-globe valve seal yenziwe ngendawo yokuvala isihlalo kanye nendawo yokuvala i-disc. Njengoba i-stem ijikeleza, i-disc ihamba ngokuqondile eduze kwe-axis yesihlalo se-valve.
Umsebenzi wevalvu yembulunga ukuvala okuphakathi ukuze kungavuzi ngokusebenzisa ukucindezela kwesiqu se-valve ukuphoqelela indawo yokuvala idiski kanye nendawo yokuvala isihlalo ukuze ilingane.
Okulandelayo izici eziyinhloko zokwakha ze-valve ye-JLPV:
1.Idizayini ye-flat disc ejwayelekile noma uhlobo lwepulaki eliyindilinga.
Isiqu nediski ziphenduka ngokukhululeka, futhi idiski ine-engeli ehlukile kuneringi yesihlalo. Lesi sitayela kucatshangwa ukuthi yisona esilula kakhulu ukusilungisa ensimini, sinikeza izinga eliphezulu lokuqinisekisa ukuvala ucingo, futhi asijwayele ukubhajwa esihlalweni somzimba.
2.Isihlalo okungenzeka ukuthi siyingxenye ebalulekile yomzimba noma isihlalo esishiselwe izinhlobo ezihlukahlukene zezinto.
Izinqubo ezigunyazwe i-WPS zilandelwa kahle lapho kushiselwa imbondela. Ubuso bendandatho yezihlalo bushintshwa ngomshini, buhlanzwe ngokucophelela, futhi buhlolwe ngemva kokushiselwa kanye nanoma yikuphi ukwelapha okushisa okudingekayo ngaphambi kokuba kuhlanganiswe.
3.Isiqu esinophawu lwebhonethi ephezulu kanye nesigxivizo sokupakisha. I-disc kanye nesiqu kuxhunywe nge-disc nut nepuleti elinendandatho ehlukanisiwe.
I-split-ring disc retainer kanye ne-disc nut isetshenziselwa ukuvikela i-disc ku-stem.Ukukhishwa kwe-fugitive ephansi kuwumphumela wobukhulu kanye nokuqedwa okunembile njengoba kuqinisekisa impilo ende kanye nokuqina okuhle kakhulu endaweni yokupakisha.
Ububanzi beI-JLPVI-globe valve design imi kanje:
1.Usayizi: 2” kuya ku-48” DN50 kuya ku-DN1200
2.Ingcindezi: Ikilasi 150lb kuya ku-2500lb PN16 kuya ku-PN420
3.Material: Insimbi ye-Carbon nensimbi engagqwali nezinye izinto ezikhethekile. I-NACE MR 0175 anti-sulphur kanye nezinto zensimbi ezilwa nokugqwala
4.Ukuxhumana kuyaphela: ASME B 16.5 ebusweni obuphakanyisiwe(RF), Ubuso obuyisicaba(FF) kanye Nokuhlanganiswa Kohlobo Lwendandatho (RTJ）I-ASME B 16.25 kuma-butt welding ends.
5.Ubukhulu bobuso nobuso: buvumelana ne-ASME B 16.10.
6.Izinga lokushisa: -29℃ ukuya ku-425 ℃
I-JLPVama-valve angafakwa ama-gear operator, ama-actuator wepneumatic, ama-Hydraulic actuators, ama-Actuator kagesi, ama-bypasses, izinto zokukhiya, ama-chainwheel, iziqu ezinwetshiwe nokunye okuningi kuyatholakala ukuze kuhlangatshezwane nezidingo zamakhasimende.
