Umgomo wokukhetha amavalvu
Ivalvu ekhethiwe kufanele ihlangabezane nezimiso ezilandelayo eziyisisekelo.
(1) Ukuphepha nokuthembeka kwe-petrochemical, isiteshi sikagesi, i-metallurgy kanye nezinye izimboni kudinga ukusebenza okuqhubekayo, okuzinzile, nomjikelezo 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, ihlangabezane nezidingo zokusebenza komjikelezo omude wedivayisi, kanye nokukhiqizwa okuqhubekayo komjikelezo omude kuyinzuzo.
(2) Ukuze kuhlangatshezwane nezidingo ze-valve yokukhiqiza inqubo, kufanele kuhlangatshezwane nokusetshenziswa kwengcindezi yokusebenza, izinga lokushisa lokusebenza kanye nezidingo zokusetshenziswa, okuyizidingo eziyisisekelo zokukhetha i-valve. Uma kudingeka indima yokuvikela i-valve ngokweqile, khipha i-medium eyeqile, kufanele ukhethe i-valve yokuphepha, i-valve yokugcwala, kudingeka kuvinjelwe inqubo yokusebenza yokugeleza okuphakathi, kufanele kusetshenziswe i-valve yokuhlola, kudingeka kususwe ngokuzenzakalelayo ipayipi lomusi kanye nemishini ye-condensate, umoya kanye nezinye igesi ezingakwazi ukufinyeza, futhi ukuze kuvinjelwe ukuphuma kwe-steam, kufanele kukhethwe i-valve yokukhipha amanzi. Ngaphezu kwalokho, uma i-medium igqwala, kufanele kukhethwe izinto ezinhle zokumelana nokugqwala.
(3) Ngemva kokusebenza, ukufakwa, ukuhlolwa (ukulungiswa) kokulungiswa kwevalvu, umqhubi kufanele akwazi ukubona kahle indlela yevalvu, izimpawu zokuvula, izimpawu zokubonisa, kube lula ukuyisingatha ngesikhathi esifanele futhi axazulule amaphutha ahlukahlukene ezimo eziphuthumayo. Ngesikhathi esifanayo, isakhiwo sohlobo lwevalvu esikhethiwe kufanele sibe lula ngangokunokwenzeka, ukufakwa, ukuhlolwa (ukulungiswa) ukulungiswa kube lula ngangokunokwenzeka.
(4) Umnotho Ngenxa yokuhlangabezana nokusetshenziswa okuvamile kwamapayipi enqubo, amavalvu anezindleko zokukhiqiza eziphansi kakhulu kanye nesakhiwo esilula kufanele akhethwe ngangokunokwenzeka ukuze kuncishiswe izindleko zedivayisi, kugwenywe ukumoshwa kwezinto zokusetshenziswa kwamavalvu futhi kuncishiswe izindleko zokufakwa nokugcinwa kwamavalvu esigabeni esilandelayo.
Izinyathelo zokukhetha ivalvu
Ukukhethwa kwama-valve ngokuvamile kulandela izinyathelo ezilandelayo:
1. Nquma isimo sokusebenza sevalvu ngokuya ngokusetshenziswa kwevalvu kudivayisi noma epayipini lenqubo. Isibonelo, indawo yokusebenza, ingcindezi yokusebenza kanye nezinga lokushisa lokusebenza, njll.
2. Nquma izinga lokusebenza kokuvala kwevalvu ngokuya ngendawo yokusebenza, indawo yokusebenza kanye nezidingo zomsebenzisi.
3. Nquma uhlobo lwevalvu kanye nemodi yokushayela ngokwenhloso yevalvu. Izinhlobo ezifanaI-valve yebhabhathane eqinile, Ivalvu yesango ehleli ngerabha,I-valve yesango ehleli ngerabha, i-valve yokulinganisela, njll. Imodi yokushayela njenge-worm wheel worm, kagesi, umoya, njll.
4. Khetha ngokwemigomo ye-valve. Ingcindezi ye-nominal kanye nosayizi we-valve kufanele kuhambisane nepayipi yenqubo efakiwe. I-valve ifakwe epayipini yenqubo, ngakho-ke isimo sayo sokusebenza kufanele sihambisane nokukhethwa komklamo wepayipi yenqubo. Ngemva kokuba uhlelo olujwayelekile kanye nomfutho we-nominal wepayipi sekunqunyiwe, ingcindezi ye-nominal ye-valve, usayizi we-nominal kanye nomklamo we-valve kanye nezindinganiso zokukhiqiza kunganqunywa. Amanye ama-valve anquma usayizi we-nominal we-valve ngokuya ngesilinganiso sokugeleza noma ukukhishwa kwe-valve ngesikhathi esilinganiselwe se-medium.
5. Nquma uhlobo lokuxhumanisa lwendawo yokugcina ivalvu kanye nepayipi ngokuya ngezimo zokusebenza zangempela kanye nosayizi ojwayelekile wevalvu. Njengeflange, ukushisela, i-wafer noma intambo, njll.
6. Nquma isakhiwo kanye nesimo sohlobo lwevalvu ngokuya ngendawo yokufaka, isikhala sokufaka, kanye nosayizi ojwayelekile wevalvu. Njengevalvu yesango elimnyama, isiqu esikhuphukayoivalvu yesango, ivalvu yebhola elungisiwe, njll.
7. Ngokuya ngezici zendlela ephakathi nendawo, ingcindezi yokusebenza kanye nokushisa kokusebenza, ukukhetha ivalvu ngendlela efanele nangokufanele.
Kwa-Tianjin Tanggu Water Seal Valve Co., Ltd., siyaziqhenya ngokuhlinzeka ngemikhiqizo yekilasi eliphezulu ehlangabezana nezindinganiso eziphakeme kakhulu embonini.
