Iivalve yebhabhathane eccentric kathathuisetyenziswa ngokubanzi kwimiba yemizi-mveliso eneemfuno ezingqongqo zokutywinwa kokusebenza kunye nokuziqhelanisa neemeko zokusebenza ngenxa yeenzuzo zayo eziphambili njengokutywinwa kwe-zero ukuvuza, uxinzelelo oluphezulu kunye nokumelana nobushushu obuphezulu, ukumelana nokuhamba okuphantsi, ukuxhathisa ukunxiba kunye nokumelana nokugqwala. Ezi zilandelayo zezona ziganeko zisetyenziswa kakhulu:

1.Ishishini lamandla ombane

Isetyenziswa ikakhulu kwiinkqubo zebhoyila (amanzi okutyisa, imibhobho yomphunga), ukuchithwa kwerhasi yeflue kunye neenkqubo zokukhupha i-denitrification, kunye neenkqubo ezijikelezayo zamanzi zezityalo zamandla ashushu kunye nezikhululo zamandla enyukliya. Umzekelo, imibhobho yomphunga ephambili yeebhoyila kunye nemibhobho yomphunga efudunyezwayo kufuneka imelane nobushushu obuphezulu (ukuya kuthi ga kwi-500℃) kunye noxinzelelo oluphezulu (ngaphezu kwe-10MPa). Ulwakhiwo lwetywina oluqinileyo lwentsimbi ye-eccentric ephindwe kathathuivelufa butterflyinokufikelela kwi-zero ukuvuza, ukuphepha inkcitho yamandla kunye neengozi zokhuseleko ezibangelwa kukuvuza komphunga. Kwinkqubo ye-desulfurization, inokumelana nokukhukuliseka kwemithombo yeendaba ezonakalisayo njenge-limestone slurry.

2.Ishishini lepetrochemical

Isebenza kwimibhobho yokuhambisa i-oyile ekrwada, iimveliso ze-oyile esulungekisiweyo, kunye nemathiriyeli ekrwada yeekhemikhali (ezifana nezisombululo ze-asidi kunye ne-alkali, izinyibilikisi zezinto eziphilayo), kunye nokulawulwa kokungena kunye nokuphuma kweenqanawa zokusabela kunye neenqaba. Umzekelo, kwimibhobho ye-oyile ekrwada yomgama omde kunye nezityalo zokusulungekiswa kunye nemichiza, ivalve yebhabhathane ene-flanged yombane enezinto ezintathu inokuqhelana nemithombo yeendaba edlekayo kunye ne-viscosity ephezulu. Okwangoku, ivula kwaye ivale ngokukhawuleza, ivumela ukunqunyulwa ngokukhawuleza okanye ukulawulwa kokuhamba okuphakathi ukuqinisekisa ukuveliswa okuqhubekayo kunye nokuzinza.

3. Ishishini lokucoca amanzi

Kubandakanya imisebenzi yamanzi, amaziko okucoca amanzi amdaka kunye neenkqubo zokucocwa kwamanzi amdaka kwimizi-mveliso. Isetyenziselwa ukuthuthwa kwamanzi acocekileyo, ukunyuswa kwamanzi amdaka, ukusetyenziswa kwakhona kwamanzi kunye namanye amakhonkco, ngakumbi kwimibhobho yogutyulo equlethe izinto eziqinileyo kunye nokungcola. Ipleyiti yayo yevalve elungelelanisiweyo inokumelana nokuhamba okuphantsi, akulula ukuyivala, kwaye ukuxhathisa kwayo kunokumelana nokukhukuliseka kwamasuntswana kugutyulo. Ukusebenza kwayo kokutywinwa kunokuthintela ukuvuza kwamanzi amdaka kwaye kubangele ungcoliseko lwesibini.

4.Ishishini leMetallurgical

Isetyenziswa kwimibhobho yegesi eqhumayo, imibhobho yomphunga wokuguqula, iinkqubo zokujikeleza kwamanzi okupholisa, imibhobho yokususa uthuli, njl njl. Itywina eliqinileyo kunye nesakhiwo esingagugiyo se-china triple eccentric butterfly valve inokusebenza ngokuzinzileyo ixesha elide. Okwangoku, umsebenzi wayo wokuvala ngokukhawuleza unokumelana neemeko eziphuthumayo kwimveliso ye-metallurgical.

5.Injineli kamasipala

Isetyenziswa kakhulu kwimibhobho yokufudumeza esezidolophini (amanzi ashushu aphezulu, umphunga) kunye nokuhanjiswa kwerhasi yendalo kunye nemibhobho yokuhambisa. Imibhobho yokufudumeza kufuneka imelane namaqondo obushushu aphezulu kunye noxinzelelo, kwaye imibhobho yerhasi yendalo ineemfuno zokutywinwa eziphezulu kakhulu (ukuthintela ukuvuza kunye nobungozi bokudubula). Izivalo zebhabhathane kwimizi-mveliso zinokulungelelanisa ukuthembeka kokutywinwa kunye nokusebenza lula, kwaye zilungele iimfuno zokusebenza kwexesha elide zothungelwano lwemibhobho kamasipala.
