Ukukhetha ivalvu yolwandle efanele kubalulekile ukuqinisekisa ukusebenza okuphephile, okusebenzayo, nokuthembekile emikhunjini nasezinhlelweni zasogwini. Njengoba kunezinhlobo eziningi zamavalvu kanye nokusetshenziswa embonini yolwandle - kusukela ezinhlelweni ze-ballast kuya kumasekethe okupholisa, imigqa kaphethiloli, kanye nokuvikelwa komlilo - ukukhetha okulungile kuncike ezintweni eziningana ezibalulekile.
1. Qonda Ukusetshenziswa kanye Nendlela Yokusebenzisa
Zonke izinhlelo zasolwandle zisingatha uhlobo oluthile loketshezi (amanzi, uwoyela, uphethiloli, umusi, njll.) ngezingcindezi ezahlukene, amazinga okushisa, kanye namazinga okugeleza.
Zibuze:
-
① Hlobo luni lwendlela egeleza ngevalvu? (isb., amanzi olwandle, amanzi ahlanzekile, uwoyela, uphethiloli, igesi, umusi)
-
②Ingabe okuphakathi kuyabola, kuyaqina, noma kuyasha?
-
③Ingabe uhlelo lokuphepha olubalulekile (isb., ukucima umlilo, ukuqhuma kwegesi, ukuvala uphethiloli)?
Icebiso:Ngezinhlelo ezigqwalisayo noma zamanzi anosawoti, khethaithusi, ithusinomaamavalvu ensimbi engagqwali.
2. Khetha Uhlobo Lwevalvu Olufanele
| Uhlobo lwe-Valve | Okuhle Kakhulu Kwaba |
|---|---|
| I-Ball Valve | Ukuvala okusheshayo, ukwehla okuncane kwengcindezi |
| I-Valve yeSango | Izinhlelo ezivulekile/ezivaliwe ngokuphelele, ezinomfutho ophansi |
| I-Globe Valve | Ukulawulwa kokugeleza noma ukugoba |
| I-Butterfly Valve | Ukonga isikhala, ukulawula ukugeleza okukhulu |
| Hlola i-Valve | Ukuvimbela ukugeleza emuva |
| I-Valve Yokuphepha | Ukuvikelwa kokucindezela ngokweqile |
| I-Storm Valve | Ukulawulwa kokukhishwa kwendle |
3. Cabanga Ngokuhambisana Nezinto Ezibalulekile
Izindawo zasolwandle zidinga izinto ezingagqwali ngenxa yokuchayeka njalo emanzini anosawoti, umswakama kanye nokushintsha kwezinga lokushisa.
-
①Ithusi/Ithusi – Ukumelana okuhle nokugqwala, okuvamile ezinhlelweni zamanzi olwandle
-
②Insimbi Engagqwali – Ukuqina okuhle kakhulu nokumelana nakho, kulungele uketshezi olunomfutho ophezulu noma olubolayo
-
③Insimbi Ebunjiwe – Isebenza kahle, kodwa ifanele uketshezi olungaboli kuphela
-
④Insimbi ye-Duplex/Super Duplex – Ama-alloy asebenza kahle kakhulu ezicelo ezisezingeni eliphezulu
Icebiso:Njalo hlanganisa izinto zevalvu nepayipi kanye nendawo ukuze ugweme ukugqwala kwe-galvanic.
4. Hlola Izilinganiso Zokucindezela Nezinga Lokushisa
-
①Hlola i-PN (Pressure Nominal) noma isilinganiso sekilasi
-
②Qinisekisa ububanzi bokushisa bokusebenza
Ama-valve kumele ahlangabezane noma adlule izidingo zesistimu futhi ahambisane nezindinganiso zomphakathi wokuhlukanisa.
5. Qinisekisa Ukuvunyelwa Kwenhlangano Yokuhlukaniswa
Wonke ama-valves olwandle kumele ahlangabezane nezindinganiso zokuphepha kolwandle zomhlaba wonke futhi avunyelwe yiNhlangano Yokuhlukaniswa efanele, njenge:I-DNV (eNorway).I-ABS (e-USA).I-BV (eFrance).Irejista kaLloyd (e-UK).I-CCS (eShayina)
Icebiso:Qinisekisa ukuthi umenzi unikeza amadokhumenti esitifiketi sevalvu ngayinye.
6. Khetha Umkhiqizi We-Marine Valve Othembekile
Khetha umhlinzeki wamavalvu olwandle o:
-
①Unesipiliyoni seminyaka eminingi embonini
-
②Inikeza ukwenza ngokwezifiso uhlelo lwakho lokusebenza
-
③Ihlinzeka ngama-valve aqinisekisiwe, ahlolwe, futhi abhalwe phansi
-
④Isekela isevisi yangemva kokuthengisa kanye nokubonisana ngobuchwepheshe
I-Qingdao I-FLOWuhola phambiliumenzi wamavalvu olwandleabaneminyaka engaphezu kweyi-10 yesipiliyoni. Sihlinzeka ngohlu oluphelele lwamavalvu asolwandle aqinisekisiwe, kufaka phakathi amavalvu esango, amavalvu omhlaba, amavalvu ebhabhathane, amavalvu okuhlola, amavalvu esiphepho, nokuningi — okukhonza imikhumbi emazweni angaphezu kwama-40 ngezitifiketi ze-CE, DNV, ABS, kanye ne-LR.
