Rawhnak timi cu zeidah a sibutterfly valves?
Butterfly valve hna i rawhnak cu a tlangpi in chemical asiloah electrochemical pawngkam nih a chuahpimi valve thir thilri rawhnak tiah hngalhthiam a si. “Rawkralnak” thil cangmi cu thir le a pawngkam pawngkam karlak ah a chuakmi pehtlaihnak ah a cang caah, thir cu a pawngkam pawngkam in zeitindah thleidan khawh a si asiloah thir a si lomi thilri tam deuh hman khawh a si timi cu rawkralnak khamnak ah a biapi bikmi a si. A pum cubutterfly valve(valve khuhnak telh chih in) nih valve ritnak tam deuh a lak i a karlak he aa tong lengmang, cucaah butterfly valve cu pum thilri chungin thim a si tawn.
Valve pum rawhnak phun hnih lawng a umbutterfly valves, cu hna cu chemical rawhnak le electrochemical rawhnak an si. A rawhnak rate cu lumnak, hneknak, thilri chemical sining le valve pum thilri rawhnak doh khawhnak nih a khiah. A rawhnak rate cu tthen paruk ah tthen khawh a si:
1. A tlingmi rawkralnak doh khawhnak: rawkralnak rate cu 0.001 mm/kum nak tlawm deuh a si;
2. A rawkralnak a doh tukmi: rawkralnak rate 0.001-0.01 mm/kum;
3. Rawkralnak doh khawhnak: rawkralnak rate 0.01-0.1 mm/kum;
4. A rawkralnak doh khawhnak sang: rawkralnak rate 0.1-1.0 mm/kum;
5. A rawkralnak doh khawhnak a ttha lo: rawkralnak rate 1.0-10 mm/kum;
6. A rawk lomi doh khawhnak: a rawkmi rate cu 10 mm/kum nak tam deuh a si.
Zeitindah a rawhnak kha kham khawh a sibutterfly valves?
Butterfly valve valve pum a rawhnak dohnak cu thilri thimnak dik ruangah a si bik. Rawkralnak dohnak kong thawngpang cu a tam tuk ko nain, a dikmi thim cu a fawi lo, zeicahtiah rawkralnak kong buainak cu a har tuk, tahchunhnak ah, sulphuric acid cu a tlawm tikah thir caah a rawk tuk, cun a tam tikah thir kha passivation film a chuahter, cu nih cun rawkralnak a kham khawh; Hydrogen cu lum le hneknak sang ah thir caah a rawk kho tukmi a si ti lawng a lang, cun chlorine gas nih a rawk khawhnak cu a ro tikah a ngan lo, asinain a rawk khawhnak cu a lum tukmi a um tikah a tthawng tuk, cun thilri tampi hman khawh a si lo. Valve pum thilri thim a harnak cu rawkralnak kong lawng si loin, hneknak le lumnak doh khawhnak, sipuazi lei in aa tlak maw tlak lo, le cawk a fawi maw fawi lo tibantuk thil hna zong kan ruah khawh. Cucaah na lungthin na pek a hau.
1. Pahnihnak cu thir, aluminium, engineering plastics, natural rubber le synthetic rubber phunphun tibantuk lining tahfung lak ding a si. A tlawm deuhmi thil sining nih a onh ahcun, hi cu khamhnak lam a si.
2. Pathumnak ah, hneknak le lumternak a sang lo tikah, fluorine-lined butterfly valve thilri bik cu rawhnak khamnak ah a ttha tuk tawn.
3. Cun, valve pum lenglei zong thli nih a hrawh, cun a nemmi thir thilri cu a tlangpi in nickel plating in a huhphenh.
TWS nih a rauh hlan ah rawkralnak dohnak thilri phun thar a chuah lai, cu nih cun valve thlennak phunphun a huap laibutterfly valves, kutka valves, check valvesle ball valves, tbk. Hi thilri phunphun nih hin a sangmi rawkralnak doh khawhnak thiamnak le thilri thlopnak phunglam hna kha a hman i riantuannak thil sining a fak tukmi tangah a ttha tukmi kharnak riantuan ning le riantuan ning fek tein a um khawh. Kannih cu a fekmi thilri sernak valve thilri hna he riantuanpi hawi hna sinah pek ding in bia kan khiah, thilri hna riantuan caan sauhter, nunchung vialte zohkhenhnak man tlawmteri thlaicycle, le thil cawtu hna kha man sang deuh cawknak biakhiahnak tuah khawhnak bawmh.
