Indlela yokukhetha yevalve yeglowubhu—i-TWS iValve

Iivalvu zeglowubhu zisetyenziswa kakhulu kwaye zineentlobo ezininzi. Ezona ndidi ziphambili zizivaluvu zeglowubhu, iglowubhu yeflange, ivalve yeglowubhu yomsonto wangaphakathi, ivalve yeglowubhu yentsimbi, ivalve yeglowubhu yeDC, iivalvu zeglowubhu yenaliti, iivalvu zeglowubu ezimilise nguY, ivalve yeglowubhu yeengile, njl. njl. , ivalve yeglowubhu yentsimbi, ivalve yeglowubhu yentsimbi; indlela yokukhetha uhlobo lubaluleke kakhulu, kufuneka lukhethwe ngokweempawu ze-medium, iqondo lokushisa, uxinzelelo kunye neemeko zokusebenza. Imithetho ethile yokhetho yile ilandelayo:

1. Ivalve yeglobhu yepneumatic kufuneka ikhethwe kumbhobho okanye isixhobo sobushushu obuphezulu kunye noxinzelelo oluphakathi. Njengobushushu obuphezulu kunye nemibhobho yoxinzelelo oluphezulu kwizityalo zamandla obushushu kunye neenkqubo zepetrochemical;

2. Ivalve yeglowubhu yokuhamba ngokuthe ngqo kufuneka isetyenziswe kumbhobho apho iimfuno zokuxhathisa i-convection azingqongqo;

3. Ivalve yenaliti, ivalve yesixhobo, ivalve yesampula, ivalve yokulinganisa uxinzelelo, njl.

4. Kukho ukulungiswa kokuhamba okanye ukulungiswa koxinzelelo, kodwa iimfuno zokuchaneka kohlengahlengiso aziphezulu, kwaye ububanzi bombhobho buncinci. Ngokomzekelo, kwipayipi ene-diameter ye-nominal ye-≤50mm, kungcono ukusebenzisa i-valve yokumisa i-pneumatic kunye ne-valve yokulawula umbane;

5. Kwi-crystallization medium-to-solidify medium, khetha ivalve yokuvala ukugcinwa kobushushu;

6. Kwiindawo zoxinzelelo oluphezulu, iivalvu zeglobhu ezibunjiweyo kufuneka zikhethwe;

7. Izichumisi ezincinci kunye nezichumisi ezinkulu kwimveliso yokwenziwa kwimizi-mveliso kufuneka zikhethe i-valve yeglobhu yoxinzelelo oluphezulu okanye i-valve ye-angle yoxinzelelo oluphezulu kunye noxinzelelo lwe-PN160 oluqhelekileyo lwe-16MPa okanye i-PN320 yoxinzelelo lwe-32MPa;

8. Kwindibano yocweyo ye-desiliconization kunye nemibhobho ethambekele ekuphekeni kwinkqubo ye-alumina Bayer, kulula ukukhetha ivalve yeglowubhu ehamba ngokuthe ngqo okanye ivalve ye-throttle flow ngqo enomzimba wevalve eyahlukileyo, isihlalo sevalve ekhutshwayo, kunye nesamente. iperi ye-carbide yokutywina;

9. Kwiiprojekthi zokubonelela ngamanzi kunye nokufudumeza kulwakhiwo lwasezidolophini, i-passage ye-nominal incinci, kwaye i-valve yokuvala i-pneumatic, i-valve yokulinganisa okanye i-valve ye-plunger ingakhethwa, umzekelo, i-nominal passage ingaphantsi kwe-150mm.

10. Kungcono ukhethe ivalve yeglowubhu ephuma kumazwe angaphandle kwi-hiqondo lobushushu umphunga kunye netyhefu kunye neendaba eziyingozi.

11. Kwivalve yeglowubhu ye-acid-base, khetha ivalve yeglowubhu yentsimbi engenastainless okanye ivalve yeglowubhu enefluorine.
