Ibhonethi yeBholnet yeGlobe yeBS 1873 yeGlobe
✧ Inkcazo
Umgangatho we-BS 1873 ubhekisa kwiBritish Standard ethile yeevalvu zeglobe ezineebhonethi ezibotshiweyo. Igama elithi "BS 1873" libonisa ukuba ivalvu ihambelana nemigangatho ebekwe yiBritish Standards Institution (BSI) yolu hlobo lwevalvu. Iglove valve enebhonethi ebotshiweyo luhlobo lwevalvu esetyenziswa rhoqo ukulawula, ukwahlula, okanye ukuthomalalisa ukuhamba kolwelo kumbhobho. Uyilo lwebhonethi ebotshiweyo luvumela ukufikelela lula kwizinto zangaphakathi zevalvu ngeenjongo zokugcinwa nokulungiswa. Ezi valve zisetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanya ioyile negesi, i-petrochemical, ukuveliswa kombane, kunye nezibonelelo zonyango lwamanzi. Iglove yebhonethi ebotshiweyo ifanelekile ukusetyenziswa apho kufuneka ukuvalwa okuqinileyo kwaye apho kufuneka ukulungiswa rhoqo okanye ukuhlolwa kwezinto zangaphakathi zevalvu. Iivalvu zeglobe zeBS 1873 ezineebhonethi ezibotshiweyo zihlala zilandela uyilo oluthile kunye nemigangatho yokusebenza echazwe kumgangatho ukuqinisekisa ukuthembeka nokusebenza kwazo. Ezi khrayitheriya zingabandakanya iinkcukacha zezinto ezisetyenzisiweyo, ukulinganiswa kobushushu boxinzelelo, uqhagamshelo lwasekupheleni, kunye nezinye iimpawu ezifanelekileyo. Xa ucacisa okanye ukhetha ivalvu yeglobhu ye-BS 1873 enebhonethi ebotshelelweyo, kubalulekile ukuqwalasela izinto ezifana nesicelo esicetywayo, iimeko zokusebenza, iimpawu zolwelo, iimfuno zoxinzelelo kunye nobushushu, kunye nayo nayiphi na imigangatho okanye imigaqo esebenzayo yoshishino. Ukuba unemibuzo ethile malunga nomgangatho we-BS 1873..
✧ Iimpawu zeBhonethi yeBhonethi yeBholethi ye-BS 1873 Globe Valve
1. Ukuvula nokuvala okungenazingxabano. Lo msebenzi usombulula ngokupheleleyo ingxaki yokuba ukutywinwa kweevalvu zemveli kuchaphazeleka kukungqubana phakathi kwemiphezulu yokutywina.
2, uhlobo oluphezulu lwesakhiwo. Ivalvu efakwe kwipayipi ingajongwa kwaye ilungiswe ngqo kwi-intanethi, nto leyo enokunciphisa ngokufanelekileyo indawo yokupaka isixhobo kwaye inciphise iindleko.
3, uyilo lwesihlalo esinye. Ingxaki yokuba i-medium ekwi-valve cavity ichatshazelwa kukunyuka koxinzelelo okungaqhelekanga iyasuswa.
4, uyilo lwe-torque ephantsi. Isiqu sevalvu esinoyilo olukhethekileyo lwesakhiwo sinokuvulwa kwaye sivalwe ngokulula ngesiphatho esincinci sesandla.
5, isakhiwo sokutywina i-wedge. I-valve ivalwe ngamandla oomatshini anikezelwa yi-valve stem, kwaye i-ball wedge icinezelwe kwisihlalo, ukuze ukutywina kwe-valve kungachaphazeleki kukutshintsha komahluko woxinzelelo lombhobho, kwaye ukusebenza kokutywina kuqinisekiswe ngokuthembekileyo phantsi kweemeko ezahlukeneyo zokusebenza.
6. Ulwakhiwo oluzicocayo lomphezulu wokutywina. Xa ibhola ithambekela kude nesihlalo, ulwelo olukwipayipi ludlula ngokulinganayo ngama-360° kumphezulu wokutywina kwebhola, okungapheleli nje ekususeni ukukhukuliseka kwendawo kolwelo olukhawulezayo kwisihlalo, kodwa kukwahlanza nokuqokelelwa komphezulu wokutywina ukuze kufezekiswe injongo yokuzicocela.
7, ububanzi bevalvu yi-DN50 ngaphantsi komzimba wevalvu, isigqubuthelo sevalvu siyinxalenye yokubumba, i-DN65 ngaphezulu komzimba wevalvu, isigqubuthelo sevalvu ziindawo zentsimbi ezibunjiweyo.
8, umzimba wevalvu kunye nesigqubuthelo sevalvu zineendlela ezahlukeneyo zokudibanisa, uqhagamshelo lwephini ye-clamp, uqhagamshelo lwe-flange gasket kunye noqhagamshelo lwentambo oluzitywinayo.
9. Umphezulu wokutywina wesihlalo sevalvu kunye neflaphu yevalvu zenziwe nge-plasma spray welding okanye i-cobalt chromium tungsten carbide engaphezulu, enobunzima obuphezulu, ukumelana nokuguguleka, ukumelana nokukrweleka kunye nobomi benkonzo ende.
10, izinto zesiqu sevalvu yintsimbi ekhupha i-nitriding, ubulukhuni bomphezulu wesiqu sevalvu ekhupha i-nitriding, ukumelana nokuguguleka, ukumelana nokukrwela, ukumelana nokugqwala, ubomi benkonzo ende.
✧ Iingenelo zeBhonethi yeBhonethi yeBholnet ye-BS 1873 Globe Valve
Ngexesha lenkqubo yokuvula nokuvala ivalvu yeglobhu yentsimbi eyenziweyo, kuba ukungqubana phakathi kwediski nomphezulu wokutywina womzimba wevalvu kuncinci kunokwevalvu yesango, ayigugi.
I-stroke yokuvula okanye yokuvala yesiqu sevalvu imfutshane kakhulu, kwaye inomsebenzi wokunqunyulwa othembekileyo kakhulu, kwaye ngenxa yokuba utshintsho lwesango lesihlalo sevalvu luhambelana ne-stroke yediski yevalvu, lufanelekile kakhulu ekulungiseni isantya sokuhamba. Ke ngoko, olu hlobo lwevalvu lufanelekile kakhulu ekunqunyulweni okanye ekulawuleni nasekugobeni.
