I-Wortied I-Palve yeSango yeStile: Imozulu yokusebenza ePhakamileyo yeziSeko zeMizi-mveliso

Xa kufikwa kwiinkqubo ezigxekayo zokulawula,I-valve enesango lentsimbiYima ngaphandle njengelitye lebala lokunyaniseka kunye nokuqina. Yenzelwe ukujamelana neengcinezelo ezigqithileyo kunye namaqondo obushushu, ezi valve zibalulekile kumashishini anjengeoyile kunye negesi, i-petrochemicals, kunye namandla esizukulwana. Ecalenii-vils ye-Globes, I-valves yensimbi yentsimbi, kwayeIivali ze-vals zensimbi, bayenza usapho lwezinto ezisebenza nzima kakhulu ezilungiselelwe ukuchaneka kunye nobomi obude.

Kutheni ukhethaIivazi zentsimbi

I-valve enentsimbi yenziwa zisebenzisa inkqubo ekhethekileyo ecinezela kunye nemilo yentsimbi phantsi koxinzelelo oluphezulu. Le ndlela iphucula ingqibelelo yezinto ezibonakalayo, esenza iicabala ziyeke ukuchitha, ukususwa nokunxiba. Izibonelelo eziphambili zibandakanya:

- Amandla aphezulu: Ilungele iindawo zoxinzelelo oluphezulu (umz.Iklasi 800lb, Iklasi 2500lb, kwayeIklasi ye-150lbiinkqubo).
- Ukuvuselelwa komsebenzi: Izakhono zokutywina ziqinisekisayo ziqinisekisa ukulahleka kwe-zero.
- Uqwalaselo: Iyahambelana ne-Steam, ioyile, igesi, kunye nemithombo yeendaba.

Ukuphonononga iindidi zeVoove kunye nezicelo zabo

I-1. Yenziwe i-value yentsimbi yentsimbi

I-vilve zesango zenzelwe / i-off yolawulo kwimibhobho. Isango labo lomtshato libonelela ngetywina eliqinileyo, ukunciphisa uxinzelelo loxinzelelo xa uvulekile ngokupheleleyo. IqhelekileIklasi ye-150,Iklasi 800to Iklasi yama-2500Iinkqubo, zigqwesa kwimibhobho ye-oyile ephezulu kunye nemibhobho yegesi.

I-Globe Volves ilawula ukuhamba kwe-disc esulelekileyo kunye nesihlalo sendima. Isakhono sabo sokujonga i-physet senza ukuba balungele iinkqubo ezifuna uhlengahlengiso rhoqo, njengamanzi apholileyo okanye imigca yokuqhubela iikhemikhali.

Ezi valves zithintela i-backflow, ukukhusela iimpompo kunye neengcingo. I-swing yazo okanye uyilo lokuphakamisa iqinisekisa ukuvalwa ngokuzenzekelayo xa ukuhamba kuhambajika, ihlala ichazwe ngaphakathiIklasi 800Iinkqubo ze-Steam.

I-valves yebhola inikezela ngokukhawuleza ngenkqubo yokuvula ikota. I-torque yabo ephantsi kunye ne-Lore-Bore-Bore-Bore iphela, kubandakanya i-LNG kunye nemibhobho yokuphucula.

Uxinzelelo loxinzelelo: Ukudibanisa iklasi ye-150, 2500 kwayeI-Palve yeSangokwiimfuno zenkqubo

- Iklasi ye-150: Iinkqubo zoxinzelelo oluphantsi (umzekelo, ukusasazwa kwamanzi).
- Iklasi 800: Iinkqubo zoNcedo lweeNdawo eziSebenzayo (umzekelo, iinethiwekhi zeSteam).
- Iklasi yama-2500: Izicelo zoxinzelelo oluphezulu (umzekelo, ukuqhuba kwe-offshore).

Ukukhetha iklasi yoxinzelelo efanelekileyo kuqinisekisa ukuthotyelwa kunye nokuthotyelwa kwemigangatho yeshishini efanaAPI 602, Asme B16.34.

Amashishini aphambili asebenzelwe

Iivalve ezinetiza zigxeka:

- Ioyile kunye negesiI-Hoods, imibhobho, kunye nee-recories.
- Izityalo zamandlaIinkqubo zotyando zeBoiler kunye ne-turbine bypass.
- Ukuqhubekeka kwamachiza: Ukuphatha i-fluids enoburharha.

Ukuqukumbela

Nokuba ufunaI-quageyodwa, aI-Wigled Gloebe Globe ValveUlawulo lokuhamba, okanye i-A **I-valve efakwe i-vawve** Uthintelo lokubuyela umva, ukhetha iklasi efanelekileyo (I-150lb, I-800lb, okanyeI-2500lb) kubalulekile. La mava evaliva adibanisa nolwakhiwo olunebhungane kunye nobunjineli obuchanekileyo, qinisekisa ukusebenza kakuhle kwezona ndawo zifunwayo.

Ukuthenjwa kwexesha elide kunye nokuthotyelwa, iqabane elinokuthenjwaabavelisiNgubani ophambili ngaphakathiI-valve yentsimbiIzisombululo. Jonga ikhathalogu yabo ukufumana ilungelo elifanelekileyo lemfundo yakho yezamashishini.
