Ivalvu yeglobe eneentambo ezisemgangathweni ophezulu yoMzi-mveliso waseTshayina Umvelisi womzi-mveliso
Yintoni ivalvu yeglobhu eneentambo?
Ivalvu yeglobhu eneentamboluyilo olukhethekileyo lweevalvu zeglobe ezincinci.
Njengevalvu yeglobe, inazo zonke iimpawu zevalvu yeglobe, ivula kwaye ivale ngokukhawuleza.
iivalvu. Njengesiqhelo, iindawo zokuvula nezokuvala zisesangweni, ezimile okwe-wedge, yiyo loo nto zibizwa ngokuba yi-wedge gate valve. Indlela isango elihamba ngayo ihambelana necala elihamba ngalo. I-wedge gate valve inokuvulwa ngokupheleleyo kwaye ivalwe ngokupheleleyo kwaye ayinakulungiswa kwaye iqhotyiswe. I-gate valve yenzelwe ukusetyenziswa nokuba ivuliwe ngokupheleleyo okanye ivalwe ngokupheleleyo.
kodwaIvalvu yeglobhu eneentamboineempawu zayo. Yenziwe ngentsimbi yekhabhoni eqiniweyo, intsimbi engatyiwayo, intsimbi ye-alloy, enomzimba omncinci, ifanelekile kulwelo olunoxinzelelo oluphezulu. Ibhonethi inokubotshwa, idityaniswe kwaye uxinzelelo luvalwe, ngokweemeko zokusebenza.
Iimpawu eziphambili zevalvu yeglobe eneentambo
Iimpawu eziphambili ze-API602ivalvu yeglobhu yentsimbi eyenziweyo
- 1) Isiqu esinyukayo ngentambo ephindwe kabini ye-acme echanekileyo ukuze isebenze ngokukhawuleza.
- 2) Ilungu lomzimba ukusuka kwibhonethi lenzelwe ukufaka umthwalo ofanayo kwi-gasket ukuqinisekisa ukuba itywina alivuzi.
- 5) Isihlalo sangasemva esenzelwe ukunciphisa uxinzelelo lwangasemva kwi-stem packing xa sihleli ngokupheleleyo. Akukhuthazwa ukutshintsha i-stem packing phantsi koxinzelelo.
- 6) Ukupakisha isiqu kwenzelwe ukulawula ngokugqibeleleyo ukuvuza komoya ophumayo emoyeni. Izinga lokuvuza komoya ophumayo eliphantsi kakhulu liqinisekiswa kukugqitywa okucolekileyo kwindawo yokutywina isiqu, ukucaca okunciphileyo kunye nolawulo lokuthe tye kwesiqu.

Umboniso weMveliso: Ivalvu yeglobhu eneentambo
Ukusetyenziswa kwevalvu yeglobhu eneentambo
Olu hloboIvalvu yeglobhu eneentamboIsetyenziswa kakhulu kwiipayipi ezinolwelo kunye nezinye izinto ezisetyenziswayo. Ipetroli, ioyile, iiKhemikhali, iiPetrochemical, amandla kunye nezixhobo zokusebenza njl.njl., ingakumbi kwiimeko apho ukusebenza kakuhle kokuhamba kwamanzi, ukuvala ngokuqinileyo kunye nenkonzo ende kufuneka. Ukhetho olubanzi lwezinto ezisetyenziswayo zegobolondo kunye ne-trim zigubungela lonke uluhlu lwezicelo, ukusuka kuhlobo lwenkonzo yemihla ngemihla engangcolisiyo ukuya kwinkonzo ebalulekileyo ene-media enamandla kakhulu.
