Pave nemakore anopfuura makumi mashanu kubva pakaunzwa katatu eccentric butterfly valve, uye yakaramba ichigadzirwa mukati memakore makumi mashanu apfuura.Kushandiswa kwemavharuvhu eshavishavi kwatekeshera mumaindasitiri akawanda.Iyo yekutanga butterfly valve inongoshandiswa pakubata uye kubatana kwemvura media.Iyo katatu eccentric dhizaini inosimudzira kushanda kwevhavhavhavhavhavha.Yakava imwe yemavharuvhu ane yakanakisa mashandiro pasi pemamiriro akaomarara mumamiriro ezvinhu akaomarara muindasitiri yemaindasitiri pombi michina.

Sezvinoratidzwa nezita racho, matatu akazvimirira offset akagadzirwa semavharuvhu.Triple eccentricity zvinoreva:

• Offset 1

Iyo shaft inoiswa kuseri kwendege yenzvimbo yekuvhara kuti ipe nzira inoenderera yechigaro.

• Offset 2

Iyo shaft inoiswa kune rumwe rutivi rwepombi / vharafu centreline kubvisa kupokana pakati pechisimbiso nechigaro

• Offset 3

Chigaro uye chisimbiso cone centerlines zvakarerekera maererano nepombi/vharuvhu centreline.Iyi yechitatu yekubvisa inobvisa zvachose kukwesha.Iyi kona yekoni, pamwe chete neaviri eccentric shaft offsets, inobvumira dhisiki kuvhara pachigaro pasina kupokana.

Iyi dhizaini yechigaro inobvumirawo kuvhara yunifomu, uye nekudaro kuvharika kwakaomarara mune dhizaini yechigaro chesimbi.Iyi dhizaini inodhura yakaderera, yakaderera torque sarudzo (iri nyore kuita otomatiki), pane imwe nzira simbi yakagarwa mavharuvhu.

Triple offsets anowanzo shandiswa mukushandisa ike high pressure steam (inopfuura 150 PSI), superheated- steam, high tembiricha magasi neoiri, tembiricha yakakwira yakanakira rudzi urwu rwevharuvhu nekuti chigaro chesimbi chinodiwa pamusoro pechigaro chakapfava.
