Iivalvu yebhabhathane engaqhelekanga kathathuIsetyenziswa kakhulu kwiimeko zoshishino ezineemfuno ezingqongqo zokusebenza kokutywina kunye nokuzivumelanisa neemeko zokusebenza ngenxa yeenzuzo zayo eziphambili ezifana nokutywina okungenalo ukuvuza, uxinzelelo oluphezulu kunye nokumelana nobushushu obuphezulu, ukumelana nokuhamba kwamanzi okuphantsi, ukumelana nokuguguleka kunye nokumelana nokugqwala. Ezi zilandelayo zezona meko zisetyenziswa kakhulu:

1. Ishishini lamandla ombane

Isetyenziswa kakhulu kwiinkqubo zebhoyila (amanzi okutya, iipayipi zomphunga), iinkqubo zokukhupha i-flue gas desulfurization kunye ne-denitrification, kunye neenkqubo zamanzi ezijikelezayo zezityalo zamandla obushushu kunye nezikhululo zamandla enyukliya. Umzekelo, iipayipi eziphambili zomphunga zebhoyila kunye neepayipi zomphunga ezifudunyezwayo kufuneka zimelane namaqondo obushushu aphezulu (ukuya kuthi ga kwi-500℃) kunye noxinzelelo oluphezulu (ngaphezulu kwe-10MPa). Ulwakhiwo lwesinyithi oluqinileyo lwe-triple eccentric.ivalvu yebhabhathaneayinakuvuza nakanye, iphephe inkunkuma yamandla kunye neengozi zokhuseleko ezibangelwa kukuvuza komphunga. Kwinkqubo yokususa i-sulfurization, inokumelana nokubola kwezinto ezibangela ukonakaliswa ezifana ne-limestone slurry.

2. Ishishini le-Petrochemical

Isebenza kwiipayipi zokuhambisa ioyile ekrwada, iimveliso zeoyile ecociweyo, kunye nezinto ezikrwada zeekhemikhali (ezifana nezisombululo ze-asidi kunye ne-alkali, izinyibilikisi zendalo), kunye nolawulo lokungena kunye nokuphuma kweenqanawa zokusabela kunye neenqaba. Umzekelo, kwiisekethe eziphakathi zemibhobho yeoyile ekrwada ekude kunye nezityalo zokucoca kunye neekhemikhali, ivalvu yebhabhathane ene-flange yombane emithathu inokuziqhelanisa nemidiya ekrwada kakhulu kunye ne-viscosity ephezulu. Okwangoku, ivula kwaye ivale ngokukhawuleza, ivumela ukucima ngokukhawuleza okanye ukulawula ukuhamba okuphakathi ukuqinisekisa imveliso eqhubekayo nezinzileyo.

3. Ishishini lokucoca amanzi

Kubandakanya imisebenzi yamanzi, izityalo zokunyanga amanzi amdaka kunye neenkqubo zokunyanga amanzi amdaka kwimizi-mveliso. Isetyenziswa ekuthuthweni kwamanzi acocekileyo, ekuphakamiseni amanzi amdaka, ekusetyenzisweni kwakhona kwamanzi asetyenzisiweyo kunye nezinye iikhonkco, ingakumbi kwimibhobho yamanzi amdaka equlethe izinto eziqinileyo ezixhonyiweyo kunye nokungcola. Ipleyiti yayo yevalvu elungelelanisiweyo inokumelana nokuhamba kwamanzi okuphantsi, akulula ukuyivala, kwaye ukumelana kwayo nokuguguleka kunokumelana nokuguguleka kwamasuntswana emanzini amdaka. Ukusebenza kwayo kokuvala kunokuthintela ukuvuza kwamanzi amdaka kwaye kubangele ungcoliseko lwesibini.

4. Ishishini lesinyithi

Isetyenziswa kwiipayipi zegesi ze-blasto-furnace, iipayipi zomphunga eziguqula umphunga, iinkqubo zokujikeleza kwamanzi okupholisa, iipayipi zokususa uthuli, njl. Igesi ye-blasto-furnace iqulethe uthuli kunye nezinto ezibolayo, kwaye ubushushu bayo buyatshintshatshintsha kakhulu. I-seal eqinileyo kunye nesakhiwo esingagugiyo se-china triple eccentric butterfly valve sinokusebenza ngokuzinzileyo ixesha elide. Okwangoku, umsebenzi wayo wokuvala ngokukhawuleza unokujongana neemeko ezingxamisekileyo kwimveliso yesinyithi.

5. Ubunjineli bukamasipala

Isetyenziswa kakhulu kwiipayipi zokufudumeza ezisemadolobheni (amanzi ashushu ashushu, umphunga) kunye neepayipi zokuhambisa nokusasaza igesi yendalo. Iipayipi zokufudumeza kufuneka zimelane nobushushu obuphezulu kunye noxinzelelo, kwaye iipayipi zegesi yendalo zineemfuno eziphezulu kakhulu zokutywina (ukuthintela ukuvuza kunye neengozi zokuqhuma). Iivalvu zebhabhathane zemizi-mveliso zinokulinganisela ukuthembeka kokutywina kunye nokusebenza lula, kwaye zifanelekile kwiimfuno zokusebenza kwexesha elide zenethiwekhi zepayipi zikamasipala.
