I-Rising Stem vs Non Rising Stem Gate Valve: Umehluko Obalulekile kanye Nezicelo Zezimboni
Ukuhlukanisa Imiklamo Yevalvu Yesango
Ama-valve esango ahlukaniswe ngokwesakhiwo sesiqu:Amavalvu Esango Lesiqu Esikhuphukayo(I-OS&Y) kanye nama-Non Rising Stem Gate Valve. Uhlobo ngalunye lunikeza izinzuzo ezihlukile zesakhiwo zokulawula ukugeleza kwezimboni.
Iyini i-Rising Stem Gate Valve
Imiklamo yesiqu esikhuphukayo ibeka isiqu senduku ngaphezu komzimba wevalvu. Ukujikeleza isiqu senduku kuphakamisa/kwehlisa isango, okunikeza:
Izinkomba Zesimo Esibonakalayo:Ukuphakama kwesiqu kukhombisa isimo sokuvula/sokuvala ngesikhathi sangempela.
Ukulungiswa Okulula: Imicu eveziwe ivumela ukuthambisa (okwandisa isikhathi sokuphila).
Ukuqina Okuphezulu: Isiqu sigwema ukuthintana noketshezi, silungele izinto ezingcolisayo (isb. uwoyela, amakhemikhali).
Izicelo: Izitshalo ze-Petrochemical, ukwelashwa kwamanzi, ukufakwa okungaphezu komhlaba.
KuyiniI-Valve Yesango Le-Stem Engaphumi
Iziqu ezingakhuphuki zine-nut yesiqu yangaphakathi emzimbeni we-valve. Ukujikeleza kuhambisa isango kuyilapho isiqu sihlala siqinile:
Ukusebenza Kahle Kwesikhala: Ukuphakama okuqinile (konga isikhala esiqondile esingu-30–50% uma kuqhathaniswa neziqu ezikhulayo).
Ukumelana Nokugqwala: Umklamo ovaliwe uvikela uthuli/ukuguguleka.
Ukuguquguquka kokufakwa: Ilungele izindawo ezixineneyo (isb., amapayipi, imikhumbi, izinhlelo zikamasipala).
Qaphela: Imicu yangaphakathi idinga ukugcotshwa ngezikhathi ezithile; izinkomba zokuvula zibalulekile.
Umehluko Obalulekile: Ama-Rising Stem Gate Valve vs Non Rising Stem Gate
| Isici | I-Rising Stem Gate Valve | I-Valve Yesango Le-Stem Engaphumi |
|---|---|---|
| Umklamo | Imicu ye-trapezoidal eveziwe | Imicu yesiqu sangaphakathi |
| Ukunyakaza Kwesiqu | Ukuphakamisa okuqondile okunesango | Ijikeleza endaweni |
| Isidingo Sesikhala | Ububanzi bevalvu obuphezulu (1.2x) | Incane |
| Ukulungiswa | Ukuthambisa okulula nokuhlola | Kuyinkimbinkimbi; kudinga ukuhlukaniswa |
| Isikhathi Sokuphila (Imijikelezo) | 100,000+ | ~50,000 |
| Okuhle Kakhulu Kwaba | Ukusebenza njalo, ukugqwala okuphezulu | Izinhlelo ezincishisiwe, ezigqitshwe yisikhala |
Iziqondiso Zokusebenza Nokukhetha
1. Izithiyo Zesikhala
Amavalvu esiqu angakhuphuki anciphisa ukuphakama ngo-30–50% kumavalvu >DN300.
2. Ukuhambisana Okuphakathi
Uketshezi olugqwalisayo? Khetha amavalvu esiqu akhuphukayo aneziqu ze-SS316L (ukumelana nokugqwala okungu-40% +).
3. Imvamisa Yokusebenza
Iziqu ezikhulayo zibekezelela imijikelezo ephindwe kabili (100k vs. 50k).
4. Umklamo Okhethekile
- Ukungavuki Ngezimbobo Zokuphambuka:Kunciphisa isando samanzi (ukwehla kokucindezeleka okungu-15–20%).
- Iziqu Ezikhuphukayo Zesivalo Esinwebekayo:Izivalo ze-PTFE zifinyelela amazinga okuvuza e-ANSI Class VI ezinhlelweni zegesi.
5. Ukuthobela Izindinganiso:
- Iziqu ezikhulayo:I-API 600 (amandla okudonsa kwesiqu ≥483 MPa).
- Iziqu ezingakhuli:Ukuhlolwa kophawu lwentambo ye-ISO 7-1.
Isiphetho: Ukufanisa I-Valve Nesicelo
Amavalvu esango lesiqu esikhuphukayo abeka phambili ukufinyelela kokunakekelwa kanye nempendulo ebonakalayo, kuyilapho amavalvu esiqu angakhuphukiyo ehamba phambili ezindaweni ezivalekile. Onjiniyela kumele balinganisele:
- Izidingo Zokunakekela (inzuzo ekhulayo yesiqu)
- Indawo Yokufaka (inzuzo yesiqu esingakhuphuki)
- Izidingo Zemidiya Nokusebenza
Lungiselela izinhlelo zokulawula ukugeleza kwamanzi namuhla ngokukhetha umklamo we-valve yesango ofanele indawo yakho yezimboni.
