ʻO ke koho kūpono o ke ʻano valve hiki ke hōʻemi i ka hoʻohana ʻana i nā mea waiwai, hoʻemi i ke kūpaʻa kūloko a me ka hoʻohana ʻana i ka ikehu, hoʻomaʻamaʻa i ka hoʻonohonoho ʻana a hōʻemi i ka mālama ʻana.Ma kēia ʻatikala, ua hōʻike ʻo Dongsheng Valve iā ʻoe i nā kiwi i hoʻohana ʻia no ka wai kai.
1.Shut-off valve
ʻO ke anawaena paipu kaʻina i ka desalination wai kai nui ʻo DN300-DN1600 maʻamau, ʻoi aku ka nui o ka hoʻohana ʻana i ka nui.kiwi poepoea me nā kiwi honua.Hoʻohālikelike ʻia me kakiwi pukao ka like kaliber (Z41H), kalele leleLoaʻa ka maikaʻi o ka hana maʻalahi, ka pale ʻana i ka corrosion maʻalahi, ka lōʻihi o ka hoʻokomo ʻana, ka emi ʻana o ke kila, a me nā coefficient kūʻē ʻāpana like o ka valve.ʻOi aku ka maikaʻi a me ka maʻalahi o ke koho ʻana i ka valve butterfly e like me ka valve pani.E like me ke kiʻekiʻe o ke kaomi, hiki ke hoʻokaʻawale ʻia nā kīwaha butterfly i loko o nā kīwaha butterfly haʻahaʻa haʻahaʻa a me nā kīwaha butterfly kiʻekiʻe.
Kiwikā lele lele haʻahaʻa
Hiki ke hoʻopaʻa ʻia ka valve butterfly haʻahaʻa haʻahaʻa i ka valve butterfly ʻaʻole i hoʻopaʻa ʻia i waena.Ke emi a i ʻole like ka valve butterfly me DN500, apono ʻia ka pilina wafer.Ke hoʻohana ʻia ka valve butterfly ≥DN550.Ke emi mai ke anawaena o ka valve butterfly ma mua o 6in.(DN150), ʻoi aku ka liʻiliʻi o ka wehe ʻana ma mua o 400N, a ke hoʻohana ʻia nei e ka lima.Ke ≥8in ke anawaena o ka valve lele.(DN200), hoʻohana ʻia me kahi pahu pahu.Ma muli o ka haʻahaʻa haʻahaʻa haʻahaʻa o ka puʻupuʻu haʻahaʻa haʻahaʻa, ʻaʻole e hoʻonui nui ʻia ka hoʻohana ʻana i ke kikowaena waena.ʻElua sila o kēia hale.Loaʻa ka sila nui e ka ikaika pre-tightening o ka papa pelelele a me ka noho valve, a loaʻa ka sila ʻelua e ka hoʻopili pono ʻana o ke kumu valve a me ka lua noho valve.No ka mea ua hoʻokaʻawale loa ʻia ka ʻōpū o ka valve mai ka waena a ʻaʻole lawe i ka wai kai, hiki ke hana ʻia ke kumu valve me 2Cr13 a i ʻole nā mea like.Hana ʻia ke kino valve me ka ductile hao lining EPDM e hoʻonui i ka hana sila.No ka mea, ʻaʻole pili ke kino valve me ka mea waena, ua hoʻemi ʻia nā pono hana o ke kino valve.
kiʻekiʻe kiʻekiʻe pēpē pēpē valve
I ke koho ʻana i nā mea kiʻekiʻe kiʻekiʻe butterfly valve, ma waho aʻe o ka noʻonoʻo ʻana i nā kumu corrosion o ka wai kai, pono e noʻonoʻo ʻia ka pale ʻana o ka mea.Ke 69bar ke kaomi hana a ʻo ≥85bar ka piʻi kiʻekiʻe (ke kaomi pani o ka reverse osmosis high-pressure pump), ma muli o ke kiʻekiʻe kiʻekiʻe o ke kua, i mea e hōʻemi ai i ka Torque, kiʻekiʻe kiʻekiʻe kaomi butterfly valve e hoʻohana i ka ʻano eccentric pālua.Ke ≤DN500 ka nui inoa o ka valve butterfly, ua aponoia ka pilina wafer.I ka ≥DN550 ka nui inoa o ka valve butterfly, apono ʻia ka pilina flange.ʻO ka helu kaomi ʻo CI600, ʻo ke kino kīpē a me ka pā papale i hana ʻia me ke kila pālua ASTMA995GR.4A.No ka mea ua ʻike ʻia ka ʻōpū o ka valve i ka waena, ua hana ʻia ka pahu valve me ASTMA276UNS31803, a ʻo ka mea noho valve ʻo RPTFE.Hoʻonui ka ʻōnaehana eccentric pālua i ke koena kūʻē kūloko.Pono e hoʻopaʻa ʻia ka pā peʻapeʻa a me ke kumu valve, a ʻo nā koi anti-corrosion o nā pine e like me nā mea kahe ʻē aʻe.
Hoʻokomo pinepine ʻia ka valve check ma ka puka o ka pā wai kai e pale ai i ke kahe hope o ka wai kai a me ka hāmare wai mai ka hōʻino ʻana i nā lako.I kēia manawa, ʻo nā kiwi hoʻopaʻa i hoʻohana ʻia i nā papahana hoʻomaʻemaʻe wai kai e pili ana i nā kiwi lele lele lohi, pani piha i ka lāʻau.nā kīwikā wafer butterfly,hoʻokahi pā wafer check valvesa me nā puʻupaʻa hoʻopaʻa hoʻopaʻa hoʻopaʻa kila duplex.
Pane lohi i ka pahu hopu lele
ʻO ka mea nui o ka valve check butterfly pani lohi ka hao ductile.ʻO ka hāmare wai hoʻopaʻa lohi a hydraulic paha he kūpaʻa maikaʻi i ka hāmare wai a kūpono no ka hoʻohana haʻahaʻa haʻahaʻa.ʻO ka noi ʻana o ka ʻāpana wai huahana o ka papahana desalination wai kai.
Kiwikā wafer check valve piha i ka lāʻau lapaʻau
He hoʻomaikaʻi maikaʻi ʻana i ka pale-corrosion o ka valve check type butterfly-type lohi.Hoʻopili piha ʻia ke kino o ka valve a me ke kumu, a hiki ke hana ʻia ka pahu valve me ke kila stainless duplex a i ʻole ke keleawe alumini nickel.Hoʻonohonoho ʻia kēia ʻano valve ma ka puka o ka pā wai kai haʻahaʻa haʻahaʻa a kūpono no ka hoʻokomo ʻana ma nā pipeline nui.ʻO ke anawaena nominal o ka valve aia ma ka laulā o DN200-1200.Pono e hoʻolohe i nā koi o ka hoʻonohonoho ʻana o ka valve i ka wā hoʻolālā.ʻO ka hoʻokomo pono ʻole ʻana o ka pahu e hana ai ka disc valve a me ka pūnāwai e hana ma luna o ke kumu valve no ka manawa lōʻihi, e hoʻopau i ka sila ma ka hoʻopili ʻana ma waena o ke kino valve a me ke kumu valve, e hoʻokomo i ka waena, a e hoʻopōʻino ke kino valve.
Hoʻokahi pā wafer check valve
He ʻano maʻalahi a me kahi wahi hoʻonohonoho liʻiliʻi o ka pahu pahu wafer lau hoʻokahi, a hiki ke hoʻohana ʻia ma lalo o ke kaomi haʻahaʻa a i ʻole nā kūlana kiʻekiʻe.Hoʻohana ka valve i ka duplex stainless steel ma ke ʻano holoʻokoʻa, he maikaʻi ke kūpaʻa ʻana o ka wai kai, ke kaumaha māmā, hiki ke hoʻokomo ʻia i ka horizontal a me ka vertically, a maʻalahi hoʻi e hoʻohana.I loko o ka mea kanu desalination wai kai, hoʻohana maʻamau ʻia kahi pahu pahu wafer check valve ≤DN250.Ke ʻoi aku ka nui o ka nui o ka valve ma mua o DN250, ʻike ʻia ka hopena o ka hāmare wai a nui ka leo hana.Hoʻohana nui ʻia ka puʻupaʻa hoʻopaʻa hoʻokahi flap nui i ka paipu kinoea.Loaʻa ka pahu piha piha ʻole, ʻo ka nui o ka wehe ʻana o ka flap valve he 45 °, piʻi ka coefficient kū'ē, a emi ke kahe kahe.
