Ama-Butterfly Valves
I-Titanium B367 Gr.C-2 API Standard Flanged Butterfly Valve
I-Triple offset ibhekisela ekungezeni i-eccentricity ye-angular eyengeziwe ngesisekelo sesakhiwo sokuhlukanisa kabili okukhulunywe ngenhla, ngisho noma indawo yokuvala ye-valve uvemvane ithambekele futhi i-conical. Isici salesi sakhiwo umshini wonqenqema lwangaphandle lwepuleti lovemvane lube endaweni eyikhonika ethambekele yangaphandle, futhi umshini wohlangothi lwangaphakathi lwesihlalo sevalvu yokuvala lube endaweni engaphakathi ethambekele eyikhonika. Kuleli qophelo, isigaba sokuvala se-valve uvemvane sesiphenduke i-elliptical, futhi ukuma kwendawo yokuvala yepuleti levemvane nakho ku-asymmetrical. Ngenxa yendawo ethambekile yokuvala uphawu, uhlangothi olukhudlwana lwepuleti uvemvane luhlukaniswa yi-valve stem shaft bese lucindezelwa phezulu lubheke esihlalweni sevalvu eduze nendawo enkulu ethambekele, kuyilapho uhlangothi oluncane lwepuleti lovemvane lucindezelwa phansi lubheke esihlalweni se-valve. eduze kwendawo encane ethambekele. Ukuvalwa phakathi kwendandatho yokuvala ipuleti uvemvane kanye nesihlalo sevalvu akuncikile ekuwohlokeni okunwebeka kwesihlalo sevalvu, kodwa ngokuphelele ekucindezelweni kwendawo ethintwayo ukuze kufinyelelwe ukuvala. Ngakho-ke, ukuvuleka nokuvalwa kwe-valve yamavemvane amathathu eccentric ngokuyisisekelo akukhuni, futhi njengoba ingcindezi yokuvala ikhula, i-valve ivala ngokuqinile futhi iqine.

Izici Ezengeziwe
Isihlalo sevalvu yevalve yevemvane eyi-eccentric senziwa ngensimbi engagqwali enqwabelene namashidi egraphite. Lesi sakhiwo singavimbela ngokuphumelelayo ithonya lezinto ezincane eziqinile phakathi nendawo kanye nokulunywa kwendawo yokuvala okungenzeka okubangelwa ukwanda kokushisa. Ngisho noma kunomonakalo omncane, ngeke kube khona ukuvuza, okungenakucatshangwa ukuthi i-valve uvemvane ene-eccentric ephindwe kabili noma amanye ama-valve evemvane angama-eccentric.
Indandatho yokuvala yevalve yovemvane eyi-eccentric kungathiwa iyingqayizivele. Akukhona nje kuphela ukuthi isihlalo se-valve esiyinhloko singashintshwa, kodwa futhi ngenxa yokuthi indawo yokuvala ipuleti ye-butterfly izimele ngaphandle kwepuleti le-butterfly, indawo yokuvala ipuleti ye-butterfly nayo ingashintshwa. Lokhu kusho ukuthi lapho indawo yokuvala ipuleti yevemvane ilimele, asikho isidingo sokuphuthuma embonini yokukhiqiza noma ukuqaqa i-valve. Indawo yokuvala kuphela yepuleti levemvane edinga ukushintshwa. Lokhu akunciphisi kakhulu kuphela izindleko zokunakekela, kodwa futhi kunciphisa kakhulu amahora okulungisa, ukuqina kokunakekela, kanye nobunzima.

Izinhlelo zokusebenza
I-valve ye-butterfly emithathu, njengokucwebezela kobuchwepheshe bamuva kuma-valve, ibonisa amandla ama-valve ahlukahlukene futhi igwema ubuthakathaka bamavalvu ahlukahlukene, ngokungangabazeki izothola ukunakwa okukhulayo kubasebenzisi nabaklami. Isilinganiso sayo sokucindezela esiphezulu singafinyelela kumakhilogremu angu-2500, ububanzi obujwayelekile bungafinyelela amasentimitha angu-48, futhi lungafaniswa nama-clamps, ama-lugs, ama-flanges, ama-ring joints, ama-butt welds, amabhantshi, ubude obuhlukahlukene besakhiwo, njll. Ngaphezu kwalokho, ngenxa yobubanzi obubanzi. yokukhethwa kwezinto ezibonakalayo, ingabuye ihambisane ngokukhululekile namazinga okushisa aphezulu naphansi, kanye nemithombo yezindaba eyonakalisayo efana ne-asidi ne-alkali. Ikakhulukazi mayelana nobubanzi obukhulu, ngenzuzo yayo yokuvuza kwe-zero, ihlala ishintsha isango elikhulu kanye nama-valve amabhola kuma-valve avaliwe. Ngokufanayo, ngokusebenza kwayo okuhle kakhulu kokulawula, iphinde ihlale ishintsha ama-valve embulunga emikhulu ekulawuleni ama-valve. Eqinisweni, isetshenziswa kumapayipi ahlukahlukene abalulekile njengokulawulwa kwenqubo emikhakheni emikhulu yezimboni efana nokukhipha uwoyela negesi, amapulatifomu angasogwini, ukucwengwa kukawoyela, amakhemikhali e-petrochemicals, amakhemikhali angaphili, kanye nokukhiqizwa kwamandla, kubandakanya neChina. Amavalvu ovemvane amathathu asetshenziswa kabanzi kumapayipi ezimboni afana ne-metallurgy, amandla, amakhemikhali kaphethiloli, ukuhlinzekwa kwamanzi kanye ne-drainage, kanye nokwakhiwa kukamasipala lapho izinga lokushisa eliphakathi liyi-≤ 425 ℃. Zisetshenziselwa ukulawula ukugeleza nokusika uketshezi.
