I-Ductile Iron Soft Seal Gate Valve VS.I-Ductile Iron Hard Seal Gate Valve
Amavalvu esango lophawu oluthambile namavalvu esango lophawu oluqinile angamadivayisi avame ukusetshenziswa okulawula nokunqanda ukugeleza, womabili asebenza kahle ngokuvala, izinhlobonhlobo zokusetshenziswa, futhi angomunye wemikhiqizo amakhasimende ayithenga kakhulu.Amanye ama-novices okuthenga angase abe nelukuluku, afana ne-valve yesango, yimuphi umehluko oqondile phakathi kwabo?
Uphawu oluthambile luwuphawu phakathi kwensimbi nokungeyona insimbi, kuyilapho uphawu oluqinile luwuphawu phakathi kwensimbi nensimbi.I-valve yesango lophawu oluthambile kanye ne-valve yesango eliqinile yizinto zokuvala, uphawu oluqinile lwenziwe ngokunemba ngomshini onempahla yesihlalo ukuze kuqinisekiswe ukunemba kokulingana ne-spool (ibhola), ngokuvamile insimbi engagqwali nethusi.Isigxivizo esithambile sishumekwe endaweni yokuvala isihlalo se-valve iyimpahla engeyona eyensimbi, ngenxa yezinto ezithambile zokuvala zinezinga elithile lokunwebeka, ngakho-ke izidingo zokunemba kokucubungula ziphansi kakhulu kunophawu oluqinile.Ngezansi kukuthatha ukuthi uqonde umehluko phakathi kwevalve yesango elithambile nevalve yesango eliqinile.
Izinto zokuqala zokuvala
1. Izinto ezimbili zokuvala zihlukile.I-valve yesango elithambile ngokuvamile iyirabha noma i-PTFE nezinye izinto.I-valve yesango yokuvala kanzima kusetshenziswa insimbi engagqwali nezinye izinsimbi.
2. Isigxivizo esithambile: ukuvala uhlangothi lwe-vice lwezinhlangothi ezimbili zezinto zensimbi, olunye uhlangothi lwezinto ezinwebekayo ezingezona ezensimbi, ezaziwa ngokuthi "uphawu oluthambile".Umphumela wokuvala wama-valve wesango anjalo, kodwa hhayi izinga lokushisa eliphakeme, kulula ukugqoka nokuklebhula, kanye nezakhiwo ezimbi zemishini.Njengensimbi + irabha;insimbi + PTFE nokunye.
3. Isigxivizo esiqinile: ukuvala okuqinile nokuvala izinhlangothi zombili kuyinsimbi noma ezinye izinto eziqinile.Ukuvalwa kwe-valve yesango okunjalo kubi, kodwa ukumelana nezinga lokushisa eliphezulu, ukumelana nokugqokwa, kanye nezakhiwo ezinhle zemishini.Okufana nensimbi + insimbi;insimbi + yethusi;insimbi + graphite;insimbi + ingxubevange yensimbi;(ingakwazi futhi ukusebenzisa insimbi ekhonjiwe, insimbi ye-alloy, i-spray paint alloy, njll.).
Okwesibili, inqubo yokwakha
Imboni yemishini inendawo yokusebenza eyinkimbinkimbi, eminingi yayo izinga lokushisa eliphansi kakhulu nokucindezela okuphansi, ukumelana nemidiya ephezulu, kanye nokugqwala.Manje, intuthuko yezobuchwepheshe iholele ekwandiseni ama-valve esango eliqinile.
Ukuze kucatshangelwe ubudlelwano phakathi kokuqina kwensimbi, i-valve yesango eliqinile, nokuvaleka okuthambile, umzimba wevalvu udinga ukuqina, kanye nepuleti levalvu nesihlalo sevalvu ukuze ziqhubeke zigaya ukuze kufinyelelwe ukuvala.Umjikelezo wokukhiqiza i-valve yesango eliqinile mude kakhulu.
Okwesithathu, ukusetshenziswa kwezimo
1, uphawu oluthambile lungabona ukuvuza kwe-zero, uphawu oluqinile lungalungiswa ngokuya ngezidingo zokuphakama nokuphansi;
2, Izimpawu ezithambile zingavuza ngaphansi kwamazinga okushisa aphezulu, zidinga ukunaka ukuvimbela umlilo, futhi izimpawu ezinzima ngeke zivuze ngaphansi kwamazinga okushisa aphezulu.I-valve yokuvala isivalo esiphuthumayo ingasetshenziswa ekucindezelweni okuphezulu, uphawu oluthambile alukwazi ukusetshenziswa.
3, kweminye imithombo yezindaba ezonakalisayo, uphawu oluthambile alukwazi ukusetshenziswa, ungasebenzisa uphawu oluqinile;
4, ekushiseni okuphansi kakhulu, impahla yophawu oluthambile izovuza, uphawu oluqinile aluyona inkinga enjalo;
Okwesine, ukukhethwa kwemishini kuvuliwe
Womabili amazinga okubeka uphawu angafinyelela ayisithupha, ngokuvamile asekelwe enkambisweni yenqubo, izinga lokushisa, nokucindezela ukuze ukhethe i-valve yesango elilungile.Ukuze uthole imidiya evamile equkethe izinhlayiya eziqinile noma i-abrasive, noma lapho izinga lokushisa lidlula ama-degree angu-200, kungcono ukhethe uphawu oluqinile.Uma i-torque ye-valve yokuvala inkulu, kufanele ukhethe ukusebenzisa i-valve yesango eliqinile eliqinile.
Okwesihlanu, umehluko empilweni yenkonzo
Inzuzo yophawu oluthambile ukubekwa uphawu okuhle, ukonakala ukuthi kulula ukuguga, ukugqoka nokudiliza, impilo emfushane.Impilo yesevisi yokuvala okunzima yinde, futhi ukusebenza kokuvala kubi kunokubeka uphawu okuthambile, kokubili kungaphelelisana.
Okungenhla umehluko phakathi kwe-valve yesango elithambile kanye nokwabelana ngolwazi lwe-valve yesango eliqinile, ngithemba ukuthi ngizokwazi ukukusiza emsebenzini wokuthenga.
