Iyini Amavalvu Esango Lommese
Amavalvu esango lommese (ama-KGV)– eyaziwa nangokuthi ama-slide gate noma ama-knife valve – amadivayisi akhethekile okulawula ukugeleza aklanyelwe ukuphatha imidiya egobile, ekhuhlayo, kanye ne-fibrous ezindaweni zezimboni ezibucayi. Lo mhlahlandlela uhlola ukwakheka kwawo, izimiso zokusebenza, kanye nezinhlelo zokusebenza ezithile zomkhakha.
Umklamo Oyinhloko kanye Nendlela Yokusebenza
Ivalvu yesango lommese isebenzisa isango elibukhali, elifana ne-blade ukuze inqume phakathi kodaka oluminyene kanye nezinto eziqinile. Izingxenye ezibalulekile zifaka:
√ Isango Le-Blade:Ipuleti elinomumo wedge (i-angle engu-5°) lisika udoti.
√Uhlelo Lokuvala:Izihlalo zensimbi/e-elastomer ziqinisekisa ukuthi akukho ukuvuza.
√Izinketho zeDrayivu:Ukusebenza ngesandla, ngomoya, ngogesi, noma ngomshini wokuhambisa amanzi.
Indlela Yokusebenza:
→ Ukuvala:I-blade iyehla, inqunde phakathi kwemidiya bese icindezela esihlalweni ukuze kube nesivalo esiqinile njengebhamuza.
→Ukuvula:Ukuhoxa okusheshayo kususa indlela yokugeleza ngokushesha, kunciphisa isikhathi sokungasebenzi.
Izinzuzo Eziyinhloko Zokusebenza
→Ukumelana Nokuguguleka:Izinto eziqinile (isib. izihlalo ze-polyurethane) zimelana nokuguguleka kwezinhlayiya.
→Umklamo Oncane:Ukwakhiwa okulula kusindisa isikhala ezitshalweni ezigcwele abantu.
→Ukuvuza Okungaphelele:Ubuchwepheshe bokuvala kabili boketshezi olunomfutho ophezulu/oluqinile.
→Ukugcinwa Okuphansi:Isakhiwo esilula sinciphisa imvamisa yokunakekelwa.
→Ukugeleza Okuqondiswa Kabili:Ivikela amapayipi ekugelezeni kwamanzi emuva.
Ukuqonda Kwemboni: Ama-KGV afakwe i-polyurethane andisa impilo yenkonzo ngo-300% emigqeni ye-slurry e-abrasive uma kuqhathaniswa nezimbozo zerabha.
Izicelo Zezimboni
Amavalvu esango lommese asebenza kahle lapho amavalvu avamile ehluleka khona:
Ukumbakanye namaminerali:
Ukuthuthwa kodaka, ukuphathwa kwemisila, ukulawulwa kodaka lwamalahle.
Isixazululo Esithandwayo:Ama-KGV ahlanganiswe nge-polyurethane amelana nokuguguleka kwe-silica/isihlabathi.
Ukwelashwa Kwamanzi Angcolile:
Iphatha indle ngemicu, utshani, kanye nezinto eziqinile.
Ukukhiqizwa Kwamandla:
Ukulawulwa kodaka lomlotha olundizayo ezitshalweni ezisebenzisa amalahle.
I-Pulp nePhepha:
Ukulawulwa kokugeleza kwe-pulp okuxinene kakhulu.
Uwoyela negesi:
Ukudluliselwa kwamafutha angcolile ngesihlabathi/itshedi.
Kungani Kufanele Ucacise Ama-Knife Gate Valve
Ukubekezelela Amatshe Angcolile: Ukwakheka kwe-blade kuvimbela ukuvaleka kwamatshe, izingcezu zokhuni, noma amatshe.
Izinketho Zokuhlanzeka: Izinto ezihambisana ne-FDA zokudla/imithi (isb., ukucubungula ubisi).
Ukusebenza Kahle Kwezindleko: izindleko zokuphila eziphansi ngo-30% uma kuqhathaniswa nama-valve ebhola kusevisi ye-slurry.
Iziqondiso Zokukhetha
I-Abrasive Media: Khetha izihlalo ze-polyurethane (ubulukhuni be-Shore A obungaphezu kuka-95).
Ama-Fluid Agqwalisayo: Cacisa imizimba yensimbi engu-316SS noma emibili.
Umsebenzi Wokujikeleza Okuphezulu: Ama-actuator azenzakalelayo emijikelezweni engaphezu kwe-100/ngosuku.
