Cheka valve: Chelete valve, eo hape e tsejoang e le valve ea tsela e le 'ngoe kapa valve ea ho hlahloba, e sebelisetsoa ho thibela bohareng ba lipeipi ho khutlela morao. Belofo e ka tlase bakeng sa ho hula le ho koala pompo ea metsi le eona ke ea sehlopha sa li-valve tsa cheke. Sesepa se itšetlehileng ka phallo le matla a seaplane ho bula kapa ho koala ka boeona, e le ho thibela sehare ho khutlela morao, se bitsoa valve ea ho hlahloba. Li-valve tsa ho hlahloba ke tsa sehlopha sa li-valve tsa othomathike. Li-valve tsa ho hlahloba li sebelisoa haholo-holo liphaepheng tse nang le phallo e sa lekanyetsoang ea mecha ea litaba, e lumellang tataiso e le 'ngoe feela ea phallo ea mecha ea litaba ho thibela likotsi. Li-valve tsa ho hlahloba li ka aroloa ka mefuta e meraro ho ea ka sebōpeho sa tsona: li-valve tsa ho phahamisa, li-valve tsa ho hlahloba li-swing, le li-valve tsa ho hlahloba serurubele. Li-valve tsa ho hlahloba li ka aroloa ka mefuta e 'meli: li-valve tsa ho hlahloba tse otlolohileng le li-valve tsa ho hlahloba tse holimo. Li-valve tsa ho hlahloba li-swing li arotsoe ka mefuta e meraro: li-valve tsa ho hlahloba disc tse le 'ngoe, li-valve tsa ho hlahloba li-disk tse peli, le li-valve tsa ho hlahloba li-disc tse ngata. Li-valve tsa ho hlahloba li-butterfly li otlolohile ka li-valve tsa ho hlahloba, 'me mefuta e ka holimo ea li-valve tsa ho hlahloba e ka aroloa ka mefuta e meraro ho ea ka khokahanyo: li-valve tsa ho hlahloba tse entsoeng ka khoele, li-valve tsa ho hlahloba li-flange, le li-valve tsa cheko tse cheselitsoeng.
Ho kenya li-valve tsa cheke ho lokela ho ela hloko lintlha tse latelang:
1. U se ke ua lumella valve ea ho hlahloba ho jara boima ba phala. Li-valve tse kholo tsa ho hlahloba li lokela ho tšehetsoa ka boithaopo ho thibela hore li se ke tsa angoa ke khatello e hlahisoang ke tsamaiso ea liphaephe.
2. Nakong ea ho kenya, ela hloko tataiso ea phallo e bohareng e lokelang ho lumellana le tataiso ea motsu e bontšitsoeng 'meleng oa valve.
3. Li-valve tsa ho hlahloba li-vertical disc tsa mofuta oa phahamisa li lokela ho kenngoa liphaepheng tse otlolohileng.
4. Mofuta oa ho phahamisa mofuta o otlolohileng oa ho hlahloba li-disc o lokela ho kenngoa phapeng e otlolohileng.
Lintlha tse ka sehloohong tsa ts'ebetso ea li-valve tsa ho hlahloba:
Khatello ea lebitso kapa boemo ba khatello: PN1.0-16.0MPa, ANSI Class150-900, JIS 10-20K, bophara ba lebitso kapa bophara: DN15 ~ 900, NPS 1/4-36, mokhoa oa ho hokahanya: flange, butt welding, khoele, sokete welding, joalo-joalo, mocheso o sebetsang: -196 ℃~540 ℃, lisebelisoa tsa 'mele oa valve: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti. Ka ho khetha lisebelisoa tse fapaneng, valve ea ho hlahloba e ka ba e loketseng mecha ea litaba e kang metsi, mouoane, oli, nitric acid, acetic acid, media oxidizing, urea, joalo-joalo.
