I-Bellows Seal Gate Valve
Yintoni ivalvu yesango le-bellows seal?
I-Bellows Seal Gate Valveyasungulwa ukuze ihlangabezane neemfuno ezingqongqo zokuqina kunye neemeko zokusebenza ezinzima.
ngaphandle kwendibano yokupakisha eqhelekileyo njenge-valve yesango lonke,ivalvu yesango lokutywina leentsimbiikwanaso nesixhobo sokupakisha esingaphantsi.
Indlela eyahlukileyo ngokupheleleyo yokupakisha sisixhobo esibizwa ngokuba yi-bellows seal, ityhubhu yesinyithi efana ne-accordion ebotshelelwe kwisiqu sevalvu nakwibhonethi, yenze isitywino esingavuziyo esinokungqubana okuncinci kwaye isitywino se-bellows siyakwazi ukolula nokucinezela ngentshukumo ethe tyaba yesiqu esityibilikayo. Njengoko i-bellows iyityhubhu yesinyithi engaphazanyiswayo, akukho ndawo kwaphela apho ukuvuza kungaphuhla khona.
Isango elikwibhonethi ende lisebenza njengendawo yokunxibelelana kwezinzwa zokubona ukuvuza kolwelo lwenkqubo, ukukhala i-alamu kunye/okanye ukuthatha inyathelo xa kukho i-bellows eqhekekileyo. Xa i-bellows seal iphuka, i-sensor iya kubona ukuvuza kwaye i-standard packing assembly iya kugcina i-seal efanelekileyo de kube kulungisiwe ivalvu.IiBellows zinobomi obulinganiselweyo bokusebenza, nto leyo ethetha ukuba kunokwenzeka ukuba ziqhekeke. Yiyo loo nto ukuhlanganiswa kwesiqhelo kokupakisha kuhlala kubandakanywa kwibhonethi exhotyiswe ngeeBellows.
Iimvuthuluka ezimile okwe-accordion zigcinwe kwaye zikhuselwe ngaphakathi kwityhubhu yesinyithi etyebileyo.Isiphelo esinye seentsimbi sidityaniswe kwisiqu sevalvu, kwaye esinye isiphelo sidityaniswe kwityhubhu ekhuselayo. Xa i-flange ebanzi yetyhubhu ibotshelelwe ngokuqinileyo kwibhonethi yevalvu, kukho isitywina esingavuziyo.
IiBellows zinobomi obulinganiselweyo benkonzo, nto leyo ethetha ukuba kunokwenzeka ukuba ziqhekeke. Yiyo loo nto ukuhlanganiswa kwesiqhelo kokupakisha kuhlala kubandakanywa kwibhonethi exhotyiswe ngeeBellows.I-bellow seal yinto eyongezelelweyo yokuvala iivalvu zesango, ifanelekile kwiimeko ezinzima zokusebenza.
Iimpawu eziphambili zevalvu yesango le-bellows seal?
Ngokukodwa kwiinkqubo zeekhemikhali, ulwelo olukwimibhobho ludla ngokuba yityhefu, lunemisebe kwaye luyingozi.Iivalvu zesango lokutywina leBellowszisetyenziselwa ukuthintela ukuvuza kwayo nayiphi na ikhemikhali enobuthi emoyeni. Izinto zomzimba zingakhethwa kuzo zonke izinto ezikhoyo, kwaye ezi zinto zingafumaneka ngezinto ezahlukeneyo ezifana ne-316Ti, 321, C276 okanye i-Alloy 625.
- 1).Iintsimbi eziqinileyo zivala isiqu esishukumayo kwaye zonyusa ukuqina kweevalvu zesitywini sesiqu ezipakishiweyo.
- 2).Izibuko lokujonga iiBellows (ukhetho): Iplagi ingaqhagamshelwa kwindawo engaphezulu kweebellows ukujonga ukusebenza.
- 3).Izitywino ezimbini zesibini zesiqu: a) Isihlalo sangasemva kwindawo evulekileyo; b) Ukupakisha iGraphite.
- 4).Kwivalvu yesango le-Bellows seal, izinto zayo ezibalulekileyo zentsimbi, isiphelo esisezantsi kunye nesiqu sevalvu ziyajijeka ngokuzenzekelayo, kwaye isiphelo esiphezulu kunye netyhubhu yokukhusela nazo ziyajijeka ngokuzenzekelayo. Umqobo wesinyithi wenziwa phakathi kwesiqu kwindawo yokungena kwayo ngomda woxinzelelo kunye nolwelo lwenkqubo ngaphakathi kwevalvu, ukuze kupheliswe ukuvuza kwesiqu;
- 5). Iivalvu ezitywinwe nge-bellow zihlala zivavanywa ukuvuza kusetyenziswa i-mass spectrometer ukubona amazinga okuvuza angaphantsi kwe-1x10E-06 std.cc/sec. Uyilo lokutywina kabini (i-bellows seal kunye ne-stem packing) ukuba ii-bellows ziyasilela, ukupakisha i-valve stem packing kuya kuthintela ukuvuza, kwaye ngokuhambelana nemigangatho yamazwe ngamazwe yokuxinana;
- 6). Iibhonethi ezivalwe ngentsimbi zixhaswa ngeseti yokupakisha yesiqu esiqhelekileyo kunye nesithuba sokujonga ukuvuza phakathi kweentsimbi kunye nokupakisha ukuze kuthintelwe ukukhutshwa kolwelo oluyingozi kakhulu xa kukho ukuvuza kweentsimbi.
- 7). Asikuko ukuba isikrufu segrisi sendabuko senzelwe umsonto wesiqu kuphela, i-grease nipple yenzelwe kwibhonethi yevalvu, singathambisa i-grease stem, i-nut kunye ne-bushing ngokuthe ngqo, ngokusebenzisa i-grease nipple;
- 8). Ivili lesandla elenziwe ngendlela ye-ergonomic, ixesha elide lenkonzo, kulula ukulisebenzisa, likhuselekile kwaye lithembekile ngakumbi;
