I-valve ye-SV10-44 eneendlela ezine ze-hydraulic ezibuyisela umva

Kwisicelo sentsimi, iivalvu ezininzi zekhatriji ezidityanisiweyo zombane azibangwa ngumgangatho wevalve elawulayo ngokwayo, kodwa ziimpazamo zofakelo ezibangelwa yindalo esingqongileyo, indawo yofakelo olungekho ngqiqweni kunye nomkhombandlela okanye imibhobho engacocekanga. Ke ngoko, kufuneka kuqwalaselwe le miba ilandelayo xa ufaka kwaye usebenzisa ivalve yokulawula yombane:

(1) Ivalve yokulawula yeyedeshibhodi kwindawo leyo, kwaye iqondo lobushushu elichaziweyo kufuneka libe kuluhlu lwe-25 ~ 60℃, kwaye ukufuma komoya kufuneka kube ≤95%. Ukuba ifakwe ngaphandle okanye kwindawo enobushushu obuphezulu obuqhubekayo, i-factory yevalve esebenza ngokuthe ngqo kufuneka ithathe amanyathelo obungqina bomswakama kunye nokunciphisa ubushushu. Kwiindawo ezinemithombo yenyikima, kuyimfuneko ukuphepha imithombo yokungcangcazela okanye ukuphucula amanyathelo okuthintela inyikima.

(2) Ngokuqhelekileyo, ivalve elawulayo kufuneka ifakwe ngokuthe nkqo, kwaye inokuthambeka phantsi kweemeko ezikhethekileyo, njengaxa i-angle yokujonga i-angle inclined inkulu kakhulu okanye ivalve ngokwayo inzima, ivalve kufuneka igcinwe ngokuphakamisa inkxaso.

(3) Phantsi kweemeko eziqhelekileyo, umbhobho wokufakelwa kwevalve yokulawula awuyi kuba phezulu kakhulu ukusuka kumphezulu wendlela okanye umgangatho weplanga. Xa ubude bombhobho bombhobho bungaphezu kwe-2m, kufuneka kusekwe iqonga lenkonzo kangangoko kunokwenzeka ukuququzelela amavili kunye nokugcinwa komsebenzisi.

(4) Phambi kokufakelwa kwevalve yolawulo, umbhobho uya kucocwa ukususa ubumdaka kunye nesiva sokuwelda.

Emva kokufaka i-valve yokukhulula i-pilot, ukuze kuqinisekiswe ukuba i-residu ayihlali kumzimba we-valve, umzimba we-valve kufuneka uhlanjululwe kwakhona, oko kukuthi, zonke iivalve zesango kufuneka zivulwe xa zingena kwi-medium ukukhusela i-residu ukuba ibambelele. . Emva kokuba isakhiwo se-spindle sisetyenziswe, kufuneka sibuyiselwe kwindawo yangaphambili yokungathathi hlangothi.

(5) Ivalve yokulawula kufuneka yongezwe kunye netyhubhu yevalve ye-bypass, ukwenzela ukuba kube lula ukwenza inkqubo yokuvelisa iqhutywe kwakhona xa kukho iingxaki okanye ukulungiswa.

Kwangaxeshanye, kufuneka sinikele ingqalelo nokuba inxalenye yofakelo yevalve yolawulo ihlangabezana neemfuno zenkqubo yonke yokucubungula.

(6) Ngokweemfuno zolwakhiwo lweeprojekthi zezixhobo zombane ezinxulumeneyo, ezinye izixhobo zombane zevalve yokulawula umbane ziya kufakelwa. Kwimeko yeempahla ezinokuthi ziqhume, kufuneka zifakwe ngokweKhowudi yoFakelo lweSixhobo soMbane kwiiNdawo eziqhumayo ezinobungozi. Uhlobo lwe-SBH okanye .3 uhlobo lwe-SBH okanye ezinye ii-cores ezintandathu okanye ezisibhozo.

Ekugcinweni kwesicelo, akuvumelekanga ukuplaga kwaye uvule isigubungelo semitha ukwenzela ukugcinwa kunye nokucoca indawo yomlilo kwiindawo ezinokutsha kunye neziqhushumbisi. Ngexesha elifanayo, akuyimfuneko ukubetha okanye ukukrazula indawo yomlilo ngexesha lokuqhaqha, kwaye imimiselo yokuqala yomlilo kufuneka ibuyiselwe emva kokugcinwa.

7 Emva kofakelo, khangela ukuba indawo yevalve iyadibana nophawu lokuvula indawo yevalvu.
