Indlela yokukhetha yevalve yeglowubhu—i-TWS iValve

Iivalvu zeglowubhu zisetyenziswa kakhulu kwaye zineentlobo ezininzi. Ezona ndidi ziphambili zizivalvu zeglowubhu, iivalvu zeglowubhu, ivalve yeglowubhu yeflange, ivalve yeglowubhu yomsonto yangaphakathi, ivalve yeglowubhu yentsimbi engenastainless, ivalve yeglowubhu yeDC, ivalve yeglowubhu yenaliti, ivalve yeglowubhu enobumba bukaY, ivalve yeglowubhu yohlobo, njl. indlela yokukhetha uhlobo lubaluleke kakhulu, kufuneka lukhethwe ngokweempawu ze-medium, iqondo lokushisa, uxinzelelo kunye neemeko zokusebenza. Imithetho yokhetho ekhethekileyo 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 ukuhanjiswa zingekho ngqongqo;

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. Kwi-workshop ye-desiliconization kunye nemibhobho ethambekele kwi-coking kwinkqubo ye-alumina ye-Bayer, kulula ukukhetha i-valve ye-globe yokuhamba ngokuthe ngqo okanye i-valve ye-throttle flow flow ngqo enomzimba wevalve eyahlukileyo, isihlalo sevalve ekhutshwayo, kunye nesementi yokutywinwa kwe-carbide;

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.
