A Ivalvu yeGlobe yoMphunga, okwaziwa ngokuba yiI-Bellows Seal Globe Valve, yivalvu yemizi-mveliso eyenzelwe ukuvala, ukusasaza, kunye nokulawula ukuhamba kwesixhobo ngokusebenzisa uxinzelelo ngesiqu sevalvu ukwenza uphawu oluqinileyo phakathi kwediski kunye nesihlalo. Yinto ebalulekileyo yolawulo esetyenziswa kakhulu kwiinkqubo zemibhobho yomphunga enobushushu obuphezulu kumashishini afana neoyile negesi, iikhemikhali, ukuveliswa kombane, kunye nesinyithi.
Ukuqonda iSteam Globe Valve kunye nendima yayo ebalulekileyo
Le valve ineentsimbi ezimbini ezidityanisiweyo kwisakhiwo sesiqu, nto leyo eyenza ukuba i-stem stem ingabi nakuphuma. Uyilo lwayo luphucula indawo yesihlalo kunye necala lamandla, nto leyo evumela uxinzelelo oluphakathi ukuba luncede ekuvaleni, ngaloo ndlela kunciphisa umngcipheko wokuvuza. Idiski yohlobo lwe-plug inendawo yokutywina ethe tyaba okanye ekhonikhi, encediswa zizakhiwo zokutywina ezineeleya ezininzi ezifana neeringi zokupakisha kunye nokupakisha okuguquguqukayo kwe-graphite ukuze kuthintelwe ukuvuza. Yakhiwe ngezinto ezifana nentsimbi yekhabhoni kunye nentsimbi engatyiwayo, ixhasa uqhagamshelo oluhlukeneyo lwesiphelo (olune-flanged, threaded, welded) kunye neendlela zokuqalisa (ngesandla, igiya, umoya). Ukufakelwa kufuna ukuqinisekisa ukuba icala eliphakathi lokuhamba lihambelana nesalathisi somzimba wevalvu; iivalvu kwimibhobho ephambili kufuneka zivivinywe amandla kunye nokuqina kwangaphambili.
Umsebenzi oPhambili: Ulawulo lokuhamba komoya oluchanekileyo kwiiNkqubo zoMphunga
Ilungu lokuvala leIvalvu yeGlobe yoMphungayidiski emile okweplagi. Umphezulu wayo wokutywina uthe tyaba okanye ukhonkrithi, kwaye idiski ihamba ngokuthe tye ecaleni komgca ophakathi wolwelo. Ngokulawula inqanaba lokuvulaivalvu yeglobhu, ulawulo oluchanekileyo lwesantya sokuhamba komphunga luyafezekiswa.
Kutheni iSteam ifuna uhlobo olukhethekileyo lweGlobe Valve
Inkonzo yomphunga ifuna iivalvu eziqinileyo ngenxa yobushushu obuphezulu kunye noxinzelelo. Iingenelo eziphambili ziquka:
