Zeziphi iimeko zemidiya ezilungele iivalvu zebhabhathane?

Iivalve zebhabhathane, ngenxa yezakhiwo zabo ezahlukeneyo kunye neefom zokutywinwa eziguquguqukayo, ziyakwazi ukuziqhelanisa neendawo ezahlukeneyo zeendaba kwaye zinokwahlulwa ngokukodwa kwezi ndidi zilandelayo:

1, Indalo yeMedia yeHlabathi

Amanzi kunye nezisombululo ezinamanzi

Ifanelekile kumajelo asekelwe kumanzi afana namanzi ahlambulukileyo, ugutyulo, amanzi olwandle, amanzi etyuwa, njl njl. Umzekelo, i-centerlineivelufa butterflyinokufikelela kwiqanda lokuvuza kokutywinwa kumanzi amatsha, ugutyulo, kunye nemo engqongileyo yamanzi olwandle ukusuka ku -10 ℃ ukuya kwi-150 ℃, kwaye iqhele ukusetyenziswa kwiindawo zokucocwa kwamanzi, unikezelo lwamanzi lukamasipala, kunye neenkqubo zokuhambisa amanzi.

Umthombo wegesi

Ifanele iigesi ezifana nomoya, igesi yendalo, igesi yamalahle, umphunga, njl. Iivalvu zebhabhathane zomoya womoya zisetyenziselwa imidiya efana neegesi ezinothuli kunye neegesi zombhobho, kwaye zifanelekile kulawulo lwebhoyila yebhoyila kunye nobunjineli bokusingqongileyo.

Oyile medium

Ifanele ioli ekrwada, ioli esulungekileyo, ioli yokuthambisa kunye nezinye ioyile. Iivalvu zebhabhathane ezitywiniweyo ezinentsimbi (ezifana neevalvu zebhabhathane eziphindwe kathathu) zinokumelana nobushushu obuphezulu kunye noxinzelelo oluphezulu, kwaye ziqhele ukusetyenziswa kwimibhobho yothutho lwe-oyile kwimizi-mveliso yepetroliyamu neyepetroli.

2, Indawo ekhethekileyo ephakathi

indawo edlekayo

Isisombululo se-alkali ye-Acid: Iivalvu zebhabhathane ezine-Fluorine ezinerabha ezinemigca yerabha zenziwe ngezinto ezikwaziyo ukumelana nomhlwa (ezifana ne-polytetrafluoroethylene kunye nerabha), zilungele izinto eziyingozi kakhulu ezifana ne-sulfuric acid, i-hydrochloric acid, kunye ne-sodium hydroxide.

Isiphakathi sekhemikhali: Isitulo sevalve yebhabhathane eccentric yentsimbi eqinileyo etywiniweyo eshicelelweyo ene-alloy enganyangekiyo kubushushu kunye ne-corrosion-resistant, ekwaziyo ukuphatha iigesi ezidliwayo kunye nolwelo olufana neklorin kunye nehydrogen chloride.

Amacandelo kunye nemithombo yeendaba eziqinileyo

Isakhiwo sokutywinwa kwe-elastic ye-centerlineivelufa butterflyiyakwazi ukuziqhelanisa ne-semi fluid kunye ne-granular media (efana nodaka, i-pulp, umgubo owomileyo), ukunqanda ukuvaleka okanye ukunxiba, kwaye isetyenziswa ngokuqhelekileyo kumashishini afana nemigodi, i-metallurgy, kunye ne-papermaking.

Ubushushu obuphezulu kunye noxinzelelo oluphakathi

Ivalve yebhabhathane ye-eccentric ithatha uyilo lwe-eccentric olunamacala amathathu, kunye nokumelana nobushushu obungaphezulu kwe-600 ℃ kunye nokumelana noxinzelelo lwe-PN40 (4.0MPa), ilungele ubushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu ezifana nokuvelisa amandla obushushu kunye neeyunithi zokuqhekeka kwepetrochemical.

3, Imithombo yeendaba ecocekileyo neyokutya

Iivalve zebhabhathane zomgangatho wokutya zenziwe ngezinto ezingeyotyhefu, ezingenavumba, kwaye kulula ukuzicoca (ezifana nentsimbi engatyiwa, i-UPVC), ehambelana nemigangatho ye-GMP kwaye ifanelekile kwimibhobho ecocekileyo kumashishini afana nokutya, isiselo, kunye namayeza ukuphepha ungcoliseko oluphakathi.
