Indlela yokhetho ye-globe-valve-valve

I-Globe Valves isetyenziswa ngokubanzi kwaye ineentlobo ezininzi. Iindidi eziphambili zibuqhetseba iivalda zangaphakathi zethabalazi, iivalves, ihlaseli ye-nenbel, ivalve egyobe, ivalve egqobhoza ivalve. Ungalukhetha njani uhlobo olubaluleke kakhulu, kufuneka ukhethwe ngokweempawu zendlela ephakathi, yobushushu, uxinzelelo kunye neemeko zomsebenzi. Imigaqo yokhetho ethile yile ilandelayo:

I-1. I-Gneumatic Globack filve kufuneka ikhethwe kumbhobho okanye isixhobo samaqondo obushushu aphezulu kunye noxinzelelo oluphezulu. Njengamaqondo obushushu aphezulu kunye nemibhobho yoxinzelelo ephezulu kwizityalo zamandla e-thermal kunye neenkqubo zepetrochemical;

2. I-Glober-Vide-Ricred Globas kufuneka isetyenziswe kumbhobho apho iimfuno zokungaxhathisi zingekho ngqongqo;

I-3. IHalve yenaliti, iHalve yeNdawo, iValping Valve, Uxinzelelo Gauge Palve, njl njl. Inokusetyenziselwa ivalve encinci yehlabathi;

4. Kukho uhlengahlengiso lokuhamba okanye uhlengahlengiso loxinzelelo, kodwa iimfuno zokulungelelaniswa ngokuchanekileyo aziphezulu, kwaye ububanzi bombhobho buncinci. Umzekelo, kumbhobho onobubanzi be-≤50mmm, kungcono ukusebenzisa i-valve ye-pneumatic yendawo yokumisa kunye nevalve yolawulo lombane;

5. Ukuqinisa i-crystalling ephakathi, khetha ivalve yokuvala ubushushu;

I-6. Kuba iindawo eziphakamileyo zoxinzelelo, ezinqatyisiweyo, ziya kukhethwa iivils zenkunzibo.

I-7.

8. Kwindibano yocweyo ye-Desionicon kunye nemibhobho ye-Alumini Bayer ye-Alumina Bayr, kulula ukukhetha ivalve efihliweyo ivali okanye ivali ye-chieff esuswayo, kunye ne-vall yebhotile yokutywina, kunye ne-vall yebhotile yokutywina, kunye ne-vall yebhotile yokutywina, kunye ne-vall yebhotile yokutywina, kunye ne-vall yebhotile yokutywina, kunye ne-vall yebhotile yokutywina, kunye ne-vall yebhotile yokutywina, kunye ne-vall yebhotile yokutywina, kunye nebhotile yebhotile yokutywina, kunye nesiqwengana sebhotsi esisusiweyo;

9. Kwindawo yokubonelela ngamanzi kunye nokufudumeza ukwakhiwa kwedolophu, indinyana etyunjiweyo incinci, kwaye i-pneumatic ivale ivalve, i-valve evaliweyo, i-valve ye-valve okanye i-platider, i-planter iphantsi kwe-150mm.

I-10. Kungcono ukhethe i-Belbeed engenisiweyo ye-velvel ye-velve ye-hI-Ibest I-Steam Steam kunye neMidiya eyityhefu neyingozi.

11. Kwi-Acid-Base Ilve Valve, khetha i-steain yensimbi ye-fielbe okanye i-fluorine-linger elinebleber.
