I-valve yebhola njengohlobo oluvame ukusetshenziswa lwe-valve emkhakheni wezimboni, ukucaciswa kwayo kuyahlukahluka, futhi ukucaciswa okuhlukile kwama-valve ebhola afanele izimo zokusebenza nezidingo ezahlukene. Lesi sihloko sizokunikeza isingeniso esiningiliziwe sezinhlobo zokucaciswa kwama-valve ebhola ukukusiza ukuthi uqonde kangcono futhi ukhethe imikhiqizo ye-valve yebhola. 1. Uhlolojikelele lwama-valve ebhola I-valve yebhola iyibhola njengezingxenye zokuvula nokuvala ze-valve, enesakhiwo esilula, ukusebenza okulula, ukusebenza kahle kokuvala uphawu nezinye izici, esetshenziswa kabanzi ku-petroleum, amakhemikhali, igesi yemvelo, ukwelashwa kwamanzi nezinye izimboni. amasimu. Ukucaciswa kwe-valve yebhola ikakhulukazi kuhilela izici ezilandelayo: 1. Impahla: impahla ye-valve yebhola ithinta ngokuqondile ukusebenza kwayo kanye nobubanzi bokusebenza, izinto ezivamile ziyi-carbon steel, insimbi engagqwali, insimbi ekhonjiwe njalonjalo. 2. Imininingwane: Ukucaciswa kwe-valve yebhola yase-China kufaka phakathi ububanzi obujwayelekile, ukucindezela okuzisholo, usayizi we-flange, njll., okunquma umthamo wokugeleza, ingcindezi kanye nemodi yokuxhuma ye-valve yebhola. 3. Izinga lokushisa: Ububanzi bokushisa obusebenzayo be-valve yebhola bunquma ikhono layo lokusebenza ngaphansi kwezimo zokusebenza ezahlukene. 4. Imodi yokushayela: Imodi yokushayela i-valve yebhola ihlanganisa i-manual, ugesi, i-pneumatic, njll, enquma imodi yokusebenza kanye nemodi yokulawula ye-valve yebhola. Okwesibili, ukucaciswa kwe-valve yebhola yase-China okunemininingwane yesingeniso 1. Ukucaciswa kwempahla: impahla ye-valve yebhola ihlukaniswe ikakhulukazi ibe yi-carbon steel, insimbi engagqwali nensimbi ephonswe, njll., ngokusho kwemvelo ehlukene yokusetshenziswa kanye nezidingo eziphakathi ukukhetha impahla efanele. (1) I-Carbon steel ball valve: ikakhulukazi eyenziwe nge-carbon steel material, enokumelana okuhle nengcindezi namandla, ifanele izinhlelo zokulawula amapayipi emkhakheni wezimboni jikelele. (2) I-valve yebhola yensimbi engagqwali: eyenziwe ngensimbi engagqwali, enokumelana nokugqwala okuhle, ifanele imidiya egqwalayo kanye nezidingo zokuhlanzeka zezikhathi eziphezulu. (3) I-valve ye-cast steel ball: eyenziwe ngensimbi yensimbi, enokumelana nengcindezi ephezulu, ukumelana nomthelela omuhle nezinye izici, ifanele izinga lokushisa eliphezulu, izinkundla zezimboni ezinomfutho ophezulu. 2. Ukucaciswa nobukhulu: Ukucaciswa kwevalvu yebhola yase-China nobukhulu ikakhulukazi kufaka phakathi ububanzi obuncane, ukucindezela okulinganiselwe kanye nosayizi we-flange. (1) I-diameter yegama: I-diameter ye-valve yebhola inquma umthamo wayo wokugeleza, ngokuvamile kusukela ku-DN15 kuya ku-DN2000, noma ngisho nangaphezulu. (2) Ukucindezela kwamagama: Ukucindezela okulinganiselwe kwe-valve yebhola kunquma amandla ayo okumelana nokucindezela, ngokuvamile kusukela ku-PN10 kuya ku-PN400. (3) Usayizi we-flange: usayizi we-flange we-valve yebhola inquma imodi yayo yokuxhumana, futhi izindinganiso ezivamile ze-flange yi-GB, ISO, ANSI, njll. izimo zokusebenza ezahlukene, okuyinto ngokuvamile ihlukaniswe izinga lokushisa eliphezulu ibhola valve, medium lokushisa ibhola valve kanye izinga lokushisa eliphansi ibhola valve. (1) I-valve yebhola yokushisa ephezulu: ifanele izimo zokushisa eziphakeme, izinga lokushisa lokusebenza lingafinyelela ku-600 ℃ noma ngaphezulu. (2) I-valve yebhola yokushisa ephakathi: ifanele izimo zokushisa eziphakathi nendawo emkhakheni wezimboni jikelele, izinga lokushisa elisebenzayo ngokuvamile liphakathi kuka -20 ℃ no-350 ℃. (3) I-valve yebhola yokushisa ephansi: ifanele izimo zokushisa eziphansi, izinga lokushisa lokusebenza lingafinyelela -40 ℃ ngezansi. 4. Imodi yokushayela: Imodi yokushayela i-valve yebhola ihlanganisa i-manual, ugesi, i-pneumatic, njll, enquma imodi yokusebenza kanye nemodi yokulawula ye-valve yebhola. (1) I-valve yebhola eyenziwa mathupha: ngokusebenzisa isiqu se-valve mathupha, ibhola liya phezulu naphansi ukuze lilawule ukucisha phakathi nendawo. (2) I-valve yebhola kagesi: amandla avuliwe, ngenjini ukuze ashayele isiqu se-valve, ukufeza ukunyakaza kwebhola phezulu naphansi, lawula imidiya ivule futhi ivale. (3) I-valve yebhola yomoya: ngokusebenzisa umthombo womoya ukushayela isilinda, ukufeza ukunyakaza kokuya phezulu naphansi kwesiqu se-valve, lawula ibhola ukuvala nokuvala. Iii. Isiphetho Imininingwane ye-valve yebhola yase-China ibanzi, ukukhetha kwe-valve yebhola efanele kudinga ukucatshangelwa ngokuvumelana nezimo ezithile zohlelo kanye nezidingo. Ukuqonda ukucaciswa okuhlukahlukene kanye nezinhlobo zama-valve ebhola kusiza ukukhetha kangcono imikhiqizo efanele, ukuze kuzuzwe umphumela wokusebenzisa ofanele. Ngithemba ukuthi lesi sihloko singakunikeza ireferensi ewusizo lapho ukhetha i-valve yebhola.
