Isimiso sokukhetha i-valve
(1)Ukuphepha nokwethembeka. I-Petrochemical, i-power station, i-metallurgy nezinye izidingo zokukhiqiza izimboni ngokuqhubekayo, ezinzile, nokusebenza komjikelezo omude. Ngakho-ke, i-valve edingekayo kufanele ibe nokuthembeka okuphezulu, isici esikhulu sokuphepha, ayikwazi ukubangela ukuphepha okukhulu kokukhiqiza kanye nokulimala komuntu siqu ngenxa yokwehluleka kwe-valve, ukuhlangabezana nezidingo zokusebenza kwesikhathi eside kwedivayisi. Ngaphezu kwalokho, nciphisa noma ugweme ukuvuza okubangelwa ama-valve, dala imboni ehlanzekile, ephucuzekile, ukuqaliswa kwezempilo, ukuphepha, ukuphathwa kwemvelo.
(2) Hlangana nezidingo zenqubo yokukhiqiza. I-valve kufanele ihlangabezane nezidingo zokusebenzisa i-medium, ingcindezi yokusebenza, izinga lokushisa lokusebenza nokusetshenziswa, okuyisidingo esiyisisekelo sokukhetha ama-valve. Uma i-valve idingeka ukuvikela ukucindezela ngokweqile nokukhipha okuphakathi ngokweqile, i-valve yokuphepha kanye ne-valve yokuchichima kuyokhethwa; ukuvimbela i-valve yokubuya ephakathi ngesikhathi senqubo yokusebenza, yamukelahlola i-valve; ukuqeda ngokuzenzakalelayo amanzi e-condensate, umoya kanye nenye igesi engajiki ekhiqizwe epayipini lesitimu nezinto zokusebenza, kuyilapho kuvimbela ukuphuma kwesitimu, kuzosetshenziswa i-valve yokukhipha amanzi. Ngaphezu kwalokho, lapho okuphakathi kugqwala, izinto ezinhle zokumelana nokugqwala kufanele zikhethwe.
(3) Ukusebenza okulula, ukufakwa kanye nokugcinwa. Ngemva kokufakwa kwe-valve, opharetha kufanele akwazi ukuhlonza kahle isiqondiso se-valve, uphawu lokuvula kanye nesignali yenkomba, ukuze abhekane namaphutha ahlukahlukene aphuthumayo. Ngesikhathi esifanayo, isakhiwo sohlobo lwe-valve ekhethiwe kufanele sibe ngangokunokwenzeka, ukufakwa okulula nokugcinwa.
(4)Umnotho. Ngaphansi kwesisekelo sokuhlangabezana nokusetshenziswa okuvamile kwamapayipi enqubo, ama-valve anezindleko eziphansi zokukhiqiza kanye nesakhiwo esilula kufanele akhethwe ngangokunokwenzeka ukuze kuncishiswe izindleko zedivayisi, kugwenywe ukumosheka kwezinto zokusetshenziswa kwama-valve futhi kuncishiswe izindleko zokufakwa nokugcinwa kwama-valve. esigabeni sakamuva.
Izinyathelo zokukhetha i-valve
1.Thola isimo sokusebenza se-valve ngokusho kokusetshenziswa kwe-valve kudivayisi noma ipayipi lenqubo. Isibonelo, i-work medium, ingcindezi yokusebenza kanye nezinga lokushisa lokusebenza, njll.
2.Thola izinga lokusebenza kokuvala i-valve ngokuya ngendawo yokusebenza, indawo yokusebenza kanye nezidingo zomsebenzisi.
3.Thola uhlobo lwe-valve kanye nemodi yokushayela ngokuvumelana nenjongo ye-valve. Izinhlobo ezifanai-butterfly valve eqinile, i-valve yokuhlola, i-valve yesango,i-valve yokulinganisa, njll. Imodi yokushayela efana ne-worm wheel worm, ugesi, i-pneumatic, njll.
4.Ngokuvumelana nepharamitha ye-valve. Ukucindezela okulinganiselwe kanye nosayizi ojwayelekile we-valve uzofaniswa nepayipi lenqubo elifakiwe. Amanye ama-valve anquma usayizi we-valve ngokwezinga lokugeleza noma ukukhishwa kwe-valve phakathi nesikhathi esilinganiselwe se-medium.
5.Nquma ifomu lokuxhuma kwendawo yokuphela kwe-valve kanye nepayipi ngokusho kwezimo zangempela zokusebenza kanye nobukhulu obujwayelekile be-valve. Okufana ne-flange, i-welding, isiqeshana noma intambo, njll.
6.Nquma isakhiwo kanye nesimo sohlobo lwe-valve ngokusho kwendawo yokufaka, indawo yokufaka, kanye nobukhulu obujwayelekile be-valve. Okufana ne-valve yesango elimnyama, i-engeli ye-globe valve, i-valve yebhola engashintshi, njll.
Ngokusho kwezici ze-medium, ingcindezi yokusebenza kanye nokushisa okusebenzayo, ekukhethweni okulungile nokunengqondo kwegobolondo le-valve nezinto zangaphakathi.
