Iivalvu zesulfure etyhidiweyo okanye ukusetyenziswa kwegesi yomsila wesulfure-Agasti 2019-IiValufa kunye ne-Automation

Iinjineli zokuyila zikaZwick ziye zacombulula iingxaki eziqhubekayo eziqubisana neevalvu kumzi-mveliso wesulfure. Kwimibhobho yobubanzi obukhulu, iingxaki eziqhelekileyo zevalvu zisukela kwizitywina ezincangathiweyo ukuya kumonakalo oqatha wesitulo sevalvu (xa ivalve kufuneka iqhutywe emva kwexesha elide lokungasebenzi). Ivalve kufuneka yonyulwe njengebhatyi yomphunga kuba le yimfuneko yesinyanzelo somgangatho. Ngokubanzi, iivalvu ezisemgangathweni zisenokufanelekela imibhobho efanelekileyo apho kungasayi kuze kubekho naliphi na ixesha lokwehla okanye amaqhuma, kuba nje ukuba ubushushu bomzimba wevalve bufikelele kubushushu bomzimba wesalfure eshushu okanye igesi yokuphuma idlule kuyo, akukho kuqina kuya kuvunyelwa. Xa umzimba wevalve upholisiwe ngenxa yokupholisa isulfure, kwenzeka imeko engaqhelekanga, ethi iqine kwindawo yokuthwala/i-shaft, ngaloo ndlela idibanisa ezi zinto. Ngokusekwe kumava ezizwe ngezizwe, iinjineli zeZwick zicebisa ukuba kusetyenziswe iivalvu ezifakwe umphunga kuba zinokugcina iindawo ezibalulekileyo kubushushu obungaguqukiyo, ngaloo ndlela ziphelise nakuphi na ukubanjwa okunokubakho. Inkampani inokubonelela nge-wafer kunye ne-valve ye-flange ephindwe kabini ngeejakethi zomphunga, kwaye sinokusebenzisa i-valve yokulandelela umphunga (isiqu kunye nediski). Iivalvu zeZwick Tri-Con zixhotyiswe ngezikhuseli ezithweleyo, ezinokunciphisa i-medium engena kwiindawo ezibaluleke kakhulu, kunye ne-bearing portable port, ibandakanya ukucocwa kokwenene kunye nokukhuselwa kwezi ndawo zibalulekileyo. Le nkcazo ilandelayo igxininisa ukungafani kobugcisa phakathi kwe-Zwick Tri-Con valve kunye nezinye iintlobo (ukusuka kwi-valve eccentric ephindwe kabini ukuya kwi-valve engenabhatyi), eya kusilela kolu hlobo lwesicelo. Uluhlu lwe-Tri-Con luyilwe ngokukodwa inkqubo yokwahlula, i-on / off kunye ne-valve yokulawula. Uluhlu lwayo olubanzi lwezicelo lukhawulelwe kuphela zizinto zangempela ezisetyenzisiweyo. Enyanisweni, iivalve eziveliswe yiZwick zifanelekile kuluhlu lweqondo lokushisa -196ºC ukuya phezulu ukuya +815ºC. Iivalvu zinokwenziwa kuyo nayiphi na ifom ye-alloy machinable ukuhlangabezana neemfuno ezithile zabathengi. Uthotho lweZwick Tri-Con yivalve ephindwe kathathu enekhowuni eyinyani kunye noyilo lwangaphakathi lwekhowuni, enokuphelisa nakuphi na ukungqubana kwisitulo sevalvu, ngaloo ndlela isusa nakuphi na ukunxiba okunokubangela ukuvuza. Kwezinye iivalvu eziqhelekileyo zokusebenza okuphezulu, oku akunakwenzeka ngokobuchwepheshe, okufana noyilo oluphindwe kabini lwe-eccentric. Njengoko ixesha lihamba, itywina lokugqibela le-15-18º friction liya kuvuza. Iivalvu eziphindwe kabini azifanelekanga kwezi zicelo zinzima. Ke ngoko, nayiphi na inzame yokuzisebenzisa inokukhokelela kwiziphumo eziyingxaki. Self-centering disc: Ngediski yembuyekezo yobushushu obuzimeleyo obubodwa, i-Tri-Con series structure inokuqinisekisa eyona ndawo ilungileyo yetywina elaminethiweyo ngokunxulumene nesihlalo sevalve. Ngoko ke, ukuphazamiseka okubangelwa ukwanda kwe-thermal kupheliswa. Ukuhanjiswa kwe-torque kunye nezitshixo: I-disc igxininiswe kwi-shaft kwaye ayilungiswanga, inikezela ukuhanjiswa kwe-torque efanayo kunye nokuphelisa umngcipheko wokuwa kwezikhonkwane. Ifilimu efanelekileyo kunye noyilo lwe-disc: I-disc eqinile kunye ne-elliptical yayo exhasayo ibonelela ngeyona mpembelelo yokulungiswa kwefilimu. Ngokusetyenziswa okukhethekileyo kwe-laminates, ukuvuza kwe-zero kunokufezekiswa. Inkxaso yokuthwala i-bushing: Indawo efanelekileyo yokuthwala inciphisa ukugoba kwe-shaft. Oku kunokuqinisekisa ukutywinwa kweendlela ezimbini phantsi koxinzelelo oluphezulu.
