Umtsetfo wekukhetsa ivalve
(1)Kuphepha kanye nekwetsembeka. Petrochemical, siteshi samandla, metallurgy kanye naletinye timboni tidzingo tekukhicita kusebenta lokuchubekako, lokuzinzile, kwemjikeleto lomudze. Ngako-ke, valve letidzingekako kufanele kube kwetsembeka lokusezingeni leliphakeme, sici lesikhulu sekuphepha, angeke kubangele kuphepha lokukhulu kwekukhicita kanye nekulimala kwemuntfu sicu ngenca yekuhluleka kwevalve, kuhlangabetana netidzingo tekusebenta kwesikhatsi lesidze kwedivayisi. Ngetulu kwaloko, nciphisa noma kugwema kuvuza lokubangelwa ngemavalvu, dala imboni lehlantekile, lephucukile, kusebenta kwemphilo, kuphepha, kulawulwa kwemvelo.
(2)Hlangabetana netidzingo tekukhicita inqubo. Le valve kumele ihlangabetane netidzingo tekusebentisa lokusemkhatsini, kucindzeteleka lokusebenta, kushisa lokusebenta kanye nekusebentisa, lokuphindze kube sidzingo lesisekelo sekukhetsa ivalve. Uma ngabe levalve idzingeka kuvikela umfutfo lomkhulu kanye nekukhipha lokungetulu kwemkhawulo, ivalve yekuphepha kanye nevalve yekuphuphuma kutawukhetfwa; kuvimbela valve lesemkhatsini yekubuya ngesikhatsi senkambo yekusebenta, yamukelahlola ivalvu; kucedza ngekuzenzakalela emanti e-condensate, umoya kanye nalenye igesi lengagucuki lekhicitwa ephayiphini lemfutfo kanye nemishini, ngesikhatsi kuvimbela kubaleka kwemphunga, kutawusetjentiswa i-valve yekukhipha. Ngekwengeta, uma lendzawo lesemkhatsini igcoba, tintfo letinhle tekumelana nekugcola kumele tikhetfwe.
(3)Kusebenta lokulula, kufakwa kanye nekunakekelwa. Ngemuva kwekufakwa kwevalve, umsebenti kufanele akhone kubona kahle indlela yevalve, luphawu lwekuvula kanye nesibonakaliso sekukhombisa, kute abhekane nemaphutsa lehlukahlukene laphutfumako. Ngesikhatsi lesifanako, isakhiwo seluhlobo lwevalve lekhetsiwe kufanele sibe kude ngangokunokwenzeka, kufakwa elula kanye nekunakekelwa.
(4)Umnotfo. Ngaphansi kwesizatfu sekuhlangabetana nekusetjentiswa lokujwayelekile kwemaphayiphi enchubo, emavalvu lanetindleko letiphansi tekukhicita kanye nesakhiwo lesilula kumele akhetfwe ngendlela lekhonakalako ngayo kunciphisa tindleko tedivayisi, kugwema kucitsa tintfo letiluhlata tevalvu kanye nekunciphisa tindleko tekufakwa kwemavalvu kanye nekunakekelwa esigabeni sakamuva.
Tinyatselo tekukhetsa ivalve
1.Determine simo sekusebenta valve ngekuya kusetjentiswa valve kudivayisi noma inqubo pipeline. Sibonelo, kusebenta medium, kusebenta umfutfo kanye lokushisa lokusebenta, njll.
2.Determine lizinga lokusebenta lokuvala kwevalve ngekuya kwendlela yekusebenta, imvelo yekusebenta kanye netidzingo temsebentisi.
3.Determine uhlobo valve kanye imodi drive ngekuya kwenjongo valve. Tinhlobo letifana na .ivalvu levivane lecinile, hlola ivalvu, ivalvu yesango,ivalvu yekulinganisela, njll Imodi yekushayela njengesibungu isondo sibungu, kagesi, pneumatic, njll.
4.Ngekuya kwepharamitha lebitwako yevalve. Umfutfo lobitwako kanye nebukhulu lobubitwako bevalve kutawuhambisana neliphayiphi lenchubo lelifakiwe. Lamanye emavalvu ancuma linani lelibitwako levalve ngekuya kwelizinga lekugeleza noma kukhishwa kwevalve ngesikhatsi lesilinganisiwe sesikhatsi lesisemkhatsini.
5.Determine ifomu uxhumano valve ekugcineni ebusweni kanye ipayipi ngekuya timo langempela ukusebenza kanye nominal usayizi valve. Njenge-flange, kushisela, siqeshana noma intambo, njll.
6.Determine isakhiwo kanye ifomu valve uhlobo ngokusho isikhundla ukufakwa, isikhala ukufakwa, kanye usayizi nominal valve. Njengevalvu yesango lendvuku lemnyama, ivalvu ye-angle globe, ivalve yebhola lelingagucuki, njll.
Ngekuya kwetimphawu letisemkhatsini, umfutfo wekusebenta kanye nekushisa lokusebenta, kuya ekukhetseni lokufanele nalokunengcondvo kwegobolondvo levalve kanye netintfo tangekhatsi.
