1. Ivalvuumgomo wokukhetha:
I-valve ekhethiwe kufanele ihlangabezane nezimiso ezilandelayo eziyisisekelo.
(1) Ukuphepha nokuthembeka kwe-petrochemical, isiteshi sikagesi, i-metallurgy nezinye izimboni kudinga ukusebenza okuqhubekayo, okuzinzile, nomjikelezo omude. Ngakho-ke, i-valve kufanele ibe nokuthembeka okuphezulu, isici sokuphepha, hhayi ngenxa yokwehluleka kwe-valve okubangelwa ukuphepha okukhulu kokukhiqiza kanye nengozi yokulimala komuntu siqu, ukuhlangabezana nemfuneko yokusebenza komjikelezo omude wedivayisi, umjikelezo omude ukukhiqizwa okuqhubekayo kuyinzuzo, ngaphezu kwalokho, ukunciphisa noma ukugwema ukuvuza okubangelwa i-valve, ukudala imboni ehlanzekile, ephucuzekile, i-HSE (okungukuthi, impilo, ukuphepha, imvelo) ukuphathwa.
(2) Ukuze uhlangabezane nezidingo zenqubo yokukhiqiza i-valve kufanele ihlangabezane nokusetshenziswa kwe-medium, ingcindezi yokusebenza, izinga lokushisa lokusebenza kanye nezidingo zokusebenzisa, okuyizidingo eziyisisekelo zokukhetha ama-valve. Uma kunesidingo, indima yokuvikela i-valve overpressure, ukukhipha okuphakathi ngokweqile, kufanele ukhethe i-valve yokuphepha, i-valve echichimayo, idinga ukuvimbela inqubo yokusebenza ye-backflow ephakathi, kufanele isebenzise i-valve yokuhlola, idinga ukuqeda ngokuzenzakalelayo ipayipi le-steam kanye nemishini ye-condensate, i-air kanye nezinye igesi engakwazi ukujiya, futhi ukuvimbela ukuphunyuka komusi, kufanele ukhethe i-valve yokukhipha. Ngaphezu kwalokho, lapho okuphakathi kugqwala, izinto ezinhle zokumelana nokugqwala kufanele zikhethwe.
(3) Ngemva kokuhlinzwa, ukufakwa, ukuhlolwa (ukulungiswa) kokulungiswa kwe-valve, umqhubi kufanele akwazi ukuhlonza kahle isiqondiso se-valve, izimpawu zokuvula, amasignali ezinkomba, ukubhekana kalula namaphutha ahlukahlukene okuphuthumayo okufika ngesikhathi futhi okuwujuqu. Ngesikhathi esifanayo, isakhiwo sohlobo lwe-valve ekhethiwe kufanele sibe ishidi le-cylinder ngangokunokwenzeka, ukufakwa, ukuhlolwa (ukugcinwa) ukulungiswa okulula.
(4) Umnotho Esakhiweni sokuhlangabezana nokusetshenziswa okujwayelekile kwamapayipi enqubo, amavalvu anezindleko eziphansi zokukhiqiza kanye nesakhiwo esilula kufanele kukhethwe ngokusemandleni ukuze kwehliswe izindleko zocingo, kugwenywe ukumosheka kwezinto ezingasetshenzisiwe zamavalvu kanye nokunciphisa izindleko zokufakwa nokugcinwa kwamavalvu esikhathini esizayo.
2. Izinyathelo zokukhetha i-valve:
Khetha ama-valve ngokuvamile alandela izinyathelo ezilandelayo.
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 lokuvala i-valve ngokuya ngendawo yokusebenza, indawo yokusebenza kanye nezidingo zomsebenzisi.
3. Thola uhlobo lwe-valve kanye nemodi yokushayela ngokuvumelana nenjongo ye-valve. Izinhlobo ezifana ne-valve yokusika, i-valve yokulawula, i-valve yokuphepha, amanye ama-valve akhethekile, njll. Imodi yokushayela njenge-worm wheel worm, ugesi, i-pneumatic, njll.
4. Khetha ngokuvumelana nemingcele ye-valve. Ukucindezela okulinganiselwe kanye nosayizi ojwayelekile we-valve uzofaniswa nepayipi lenqubo elifakiwe. I-valve ifakwe epayipini lenqubo, ngakho-ke isimo sayo sokusebenza kufanele sihambisane nokukhethwa komklamo wepayipi lenqubo. Ngemva kokunqunywa kwesistimu evamile kanye nomfutho wegazi wepayipi, ingcindezi ye-valve igama, ubukhulu begama kanye nomklamo we-valve kanye namazinga okukhiqiza anganqunywa. Amanye ama-valve anquma usayizi we-valve ngokwezinga lokugeleza noma ukukhishwa kwe-valve phakathi nesikhathi esilinganiselwe se-medium.
5. Nquma ifomu lokuxhuma le-valve ekupheleni kwendawo kanye nepayipi ngokusho kwezimo zangempela zokusebenza kanye nobukhulu obujwayelekile be-valve. Okufana ne-flange, i-welding, isiqeshana noma intambo, njll.
6. Nquma isakhiwo kanye nohlobo lohlobo lwe-valve ngokusho kwendawo yokufaka, indawo yokufaka, kanye nobukhulu begama le-valve. Okufana ne-valve yesango lenduku emnyama, i-engeli ye-globe valve, i-valve yebhola engashintshi, njll.
7. Ngokwezici ze-medium, ingcindezi yokusebenza kanye nokushisa okusebenzayo, ekukhethweni okulungile nokunengqondo kwegobolondo le-valve nezinto zangaphakathi.
Ngaphandle kwalokho,I-Tianjin Tanggu Water Seal Valve Co., Ltd. iyi-valve yesihlalo enwebekayo esezingeni eliphezulu esekela amabhizinisi, imikhiqizo i-elastic seat wafer butterfly valve,i-lug butterfly valve, i-valve ye-butterfly ene-flange ephindwe kabili, i-valve ye-butterfly ene-flange ephindwe kabili, i-valve yebhalansi,i-valve yokuhlola ipuleti elicwecwe kabili, Y-Strainer nokunye. E-Tianjin Tanggu Water Seal Valve Co., Ltd., siyaziqhenya ngokuhlinzeka ngemikhiqizo esezingeni eliphezulu ehlangabezana namazinga aphezulu embonini. Ngohlu lwethu olubanzi lwama-valve nokufakwa, ungasethemba ukuthi sizokunikeza isisombululo esiphelele sohlelo lwakho lwamanzi. Xhumana nathi namuhla ukuze ufunde kabanzi mayelana nemikhiqizo yethu nokuthi singakusiza kanjani.
