I-Rising Stem vs Non Rising Stem Gate Valve: Umahluko obalulekileyo kunye nezicelo zemizi-mveliso
Uyilo lweeValve zeSango lokuHlela
Iivalvu zesango zahlulwe ngokwendlela yoyilo lwesiqu:Iivalvu zeSango leSitem esiKhulayo(I-OS&Y) kunye neeValve zeSango leStem eliNgeliyo. Uhlobo ngalunye lubonelela ngeenzuzo ezahlukeneyo zesakhiwo zokulawula ukuhamba kwamanzi kwimizi-mveliso.
Yintoni iValve yeSango eliKhuphukayo
Uyilo lwesiqu olunyukayo lubeka isiqu se-nut ngaphezulu komzimba wevalvu. Ukujikeleza isiqu se-nut kuphakamisa/kwehlisa isango, okubonelela:
Izalathisi zeNdawo yokuBonwa:Ukuphakama kwesiqu kubonisa imeko yokuvula/yokuvala ngexesha langempela.
Ukugcinwa okulula: Imisonto eveziweyo ivumela ukuthambisa (ukwandisa ubomi).
Ukuqina Okuphezulu: Isiqu siyayiphepha into yokudibana nolwelo, ilungele ukusetyenziswa kwezinto ezingcolisayo (umz., ioyile, iikhemikhali).
Izicelo: Izityalo zePetrochemical, unyango lwamanzi, ukufakelwa ngaphezulu komhlaba.
Yintoni iI-Valve yeSango leStem eliNgaphumiyo
Iziqu ezingakhuliyo zine-nut yesiqu sangaphakathi ngaphakathi komzimba wevalvu. Ukujikeleza kuhambisa isango ngelixa isiqu sihleli simile:
Ukusebenza kakuhle kwesithuba: Ukuphakama okuncinci (konga isithuba esithe nkqo esingama-30–50% xa kuthelekiswa neziqu ezikhulayo).
Ukumelana nokugqwala: Uyilo oluvaliweyo lukhusela uthuli/ukukhukuliseka.
Ukuguquguquka kokufakwa: Ifanelekile kwiindawo ezixineneyo (umz., imibhobho, iinqanawa, iinkqubo zikamasipala).
Qaphela: Imisonto yangaphakathi ifuna ukuthambisa rhoqo; izalathisi zokuvula zibalulekile.
Umahluko oPhambili: IiValve zeGate yeRising Stem vs Non Rising Stem
| Uphawu | Ivalvu yeSango leStem eliKhuphukayo | I-Valve yeSango leStem eliNgaphumiyo |
|---|---|---|
| Uyilo | Imisonto yetrapezoidal eveziweyo | Imisonto yesiqu sangaphakathi |
| Ukuhamba kweStem | Ukuphakanyiswa okuthe nkqo okunesango | Ijikeleza endaweni yayo |
| Imfuneko Yesithuba | Ukuphakama (ububanzi bevalvu eyi-1.2x) | Incinci |
| Ulondolozo | Ukuthambisa okulula kunye nokuhlolwa | Intsonkothile; ifuna ukuqhaqhwa |
| Ubude bobomi (Iindlela zokujikeleza) | 100,000+ | ~50,000 |
| Eyona ilungileyo | Ukusebenza rhoqo, ukugqwala okuphezulu | Iinkqubo ezixineneyo, ezingcwatyiweyo |
Izikhokelo Zokusebenza Nokukhetha
1. Imida Yendawo
Iivalvu zesiqu ezinganyukiyo zinciphisa ukuphakama ngama-30–50% kwiivalvu >DN300.
2. Ukuhambelana okuPhakathi
Ngaba kukho ulwelo oludlakazelayo? Khetha iivalvu zesiqu ezinyukayo ezineziqu ze-SS316L (ezinokumelana nokugqwala ezingama-40% nangaphezulu).
3. Ubuninzi bokusebenza
Iziqu ezikhulayo zinyamezela imijikelo ephindwe kabini (100k vs. 50k).
4. Uyilo oluKhethekileyo
- Ukunganyuki NgeeHole Eziphambukayo:Inciphisa ihamile yamanzi (ukuhla koxinzelelo nge-15–20%).
- Iziqu Ezinyukayo Zesitywina Esithambileyo:Izitywino ze-PTFE zifezekisa imigangatho yokuvuza ye-ANSI Class VI kwiinkqubo zegesi.
5. Ukuthobela iMigangatho:
- Iziqu ezikhulayo:I-API 600 (amandla okutsalwa kwesiqu ≥483 MPa).
- Iziqu ezingakhuliyo:Uvavanyo lwetywina lomsonto lwe-ISO 7-1.
Isiphelo: Ukufanisa iValve neSicelo
Iivalvu zesango lesiqu esinyukayo zibeka phambili ukufikelela kulondolozo kunye nempendulo ebonakalayo, ngelixa iivalvu zesiqu ezinganyukiyo zigqwesa kwiindawo ezixineneyo. Iinjineli kufuneka zilinganisele oku kulandelayo:
- Iimfuno zoLondolozo (inzuzo ekhulayo yesiqu)
- Indawo yoFakelo (inzuzo yesiqu esinganyukiyo)
- Iimfuno zeMidiya kunye nezoKusebenza
Lungiselela iinkqubo zokulawula ukuhamba kwamanzi namhlanje ngokukhetha uyilo lwevalvu yesango olufanelekileyo kwindawo yakho yemizi-mveliso.
