I-Flange Globe Valve

Singumenzi wamavalvu ochwepheshe ophethe izitifiketi ze-ISO, CE kanye ne-API. Siphethe imishini yokukhiqiza ethuthukisiwe kanye nesethi egcwele yezinhlelo zokulawula ikhwalithi. Futhi samukela ama-oda we-OEM ne-ODM, anamanani amancane avumelana nezimo. Imikhiqizo yethu ethembekile ithunyelwa emhlabeni wonke futhi izuza ukuqashelwa okubanzi kumakhasimende.

Isebenza kanjani?

Vula isondo lesandla ukuze uphakamise noma wehlise idiski yangaphakathi ngokumelene nesihlalo sevalvu. Spina isondo lesandla ukuze uhambise idiski elingaphakathi phezulu noma phansi ngokumelene nesihlalo. Phakamisa idiski phakathi nendawo ukuze wehlise ijubane uketshezi, noma uliphakamise ngokugcwele ukuze uthole ukugeleza okukhulu. Phusha i-disc iqine esihlalweni ukuze umise ngokuphelele ukugeleza. Lokhu kusetha kukuvumela ukuthi ulungise ivolumu yokugeleza kahle kungakhathaliseki ukuthi i-valve ivuleke kangakanani.

Izimfanelo Ezibalulekile

Yiziphi izinzuzo eziyinhloko?

Inzuzo evelele ukulungisa ukugeleza okunembile, isici se-valve yebhola asikwazi ukuphatha kahle. Ivala ngokuqinile ukuze igweme ukuvuza ngokuphelele. Umzimba oqinile owugqinsi usebenza kancane ngaphansi kokushisa okuphezulu nokucindezela. Ama-seal nama-disc angashintshwa khona kanye esizeni ngaphandle kokukhipha i-valve yonke, kuncishiswe isikhathi sakho sokunakekela kanye nezindleko.

Zisetshenziswa kuphi?

Ama-valve e-Flange Globe ajwayelekile kuzo zonke izinhlobo zamapayipi ezimboni. Ungawathola kumasekhethi omusi esitshalweni sikagesi, imigqa yokukhiqiza amakhemikhali, izindawo zokuhlanza amanzi, amapayipi okulethwa kukawoyela negesi, kanye namanzi ashisayo namasistimu okushisa isitimu.

I-Flanged vs. Intambo?

Ama-valve embulunga enama-flanged akhiyela emapayipini anama-flange aboshwe. Zisekela ububanzi obukhulu nokucindezela okuphezulu kokusebenza, futhi ungakwazi ukuhlukanisa ngokushesha i-valve kumapayipi ukuze ihlolwe noma ilungiswe. Izinguqulo ezinemicu zigoqa ziqonde kumapayipi amancane, afanele kuphela osayizi abancane nemigqa enengcindezi ephansi. Amajoyinti anemicu ajwayele ukubamba ngemva kwenkonzo ende futhi anzima kakhulu ukuwahlakaza kamuva.

Iyini i-Flange Globe Valve?

I-valve ye-flange globe iyi-valve yezimboni evalayo futhi edonsayo eneziphetho zokuxhuma kwe-flange. Ilawula ukugeleza koketshezi ngokuphakamisa nokwehlisa i-disc ngaphakathi komzimba we-valve. Idizayini ye-flange yenza ukuhlanganiswa kwamapayipi asheshayo, aqinile kanye nokuqaqa kalula ukuze kulungiswe, kusetshenziswe kabanzi kuzo zonke izinhlobo zezinhlelo zamapayipi ezimbonini.

Kungani ukhetha uxhumano lwe-flange esikhundleni sentambo noma ukuphela kwe-weld?

A: Ukuxhumeka kwe-Flange kulula ukukuqaqa ukuze kulungiswe kabusha i-valve noma ukushintshwa ngaphandle kokusika amapayipi. Indawo yokuxhumana ye-flange gasket inikeza umphumela wokuvala ozinzile, ofaneleka kakhulu ububanzi obukhulu, ukucindezela okuphezulu kanye nezimo zokusebenza zokugcinwa njalo. Ama-valve anemicu amapayipi amancane anengcindezi encane kuphela.

Yiziphi amaphuzu abalulekile okufakwa kwe-flange?

Hlanza i-slag yokushisela, ukugqwala kanye nemfucumfucu endaweni yokuvala i-flange ngaphambi kokufakwa;

Qondanisa ama-gaskets ajwayelekile ngokwezinga lokushisa eliphakathi nendawo (i-graphite yezinga lokushisa eliphakeme, i-PTFE yokugqwala);

Qinisa amabhawodi e-flange ngokulinganayo nangokulinganayo ukuze ugweme ukuvuza kokucindezeleka okungalingani;

Ungawaqinisi kakhulu amabhawodi ukuze uchoboze futhi ulimaze i-gasket.

Ungayigcina kanjani i-valve ye-flange ukuze unwebe impilo yesevisi?

Gcoba isiqu se-valve kanye njalo ezinyangeni ezintathu ukuze singabambeki.

Phinda wenze i-torque kuwo wonke amabhawodi e-flange uma ipayipi lezinga eliphezulu lokushisa selishisele ngokuphelele.

Sula noma yiluphi uketshezi olushisayo olusele ngaphakathi kwamavalvu uma uhlela ukuvala isistimu isikhathi eside.

Ama-valve alindile omjikelezo avuleka futhi avalwe njengenjwayelo ukuze amise ukugqwala kwezingxenye zangaphakathi.
