Ndeipi miganho yekushanda yakajairika?

Iyi carbon steel globe valve inochengetedza kushanda kwakachengeteka mukati mekushanda kwekushisa kwe -29 ℃ kusvika 425 ℃. Kana ichishanda pasi peiyo inofananidzwa nezita rekumanikidza kirasi, inoramba ichienderana yakavharika chisimbiso pasina kuvuza, uye iyo yakakosha valve chimiro chinogara chakasimba uye deformation-isina. Iyo inobata kuita kwakadzikama panguva yekutenderera-ye-wachi kuenderera mberi kwekushanda kwemaindasitiri, kutarisana nekuvhurika nekuvhara nguva nenguva pamwe nekushanduka kwekushisa kwekushanda.

Inoshandiswa nei?

Iri vharuvhu rakagadzirirwa maviri akakosha onsite mabasa: yakanaka kuyerera mutemo uye yakazara pombi yekuparadzaniswa. Inoshanda zvakakwana nemvura, mafuta emafuta, gasi rechisikigo, chiutsi uye huwandu hwakawanda hwezvakajairwa maindasitiri maitiro emvura. Iwe unogona kazhinji kuiwana yakaiswa pamapaipi network emafekitori emakemikari, petrochemical processing mitsara, zviteshi zvemagetsi zvinopisa, nzvimbo dzekuchenesa mvura yetsvina uye mashopu ekugadzira akajairwa, achinyatso kudzora kuendesa kwepakati mumarudzi ese epakati uye akakwira tembiricha maindasitiri masisitimu.

Sei uchisarudza kabhoni simbi?

Isu tinoshandisa A216 WCB kabhoni simbi kukanda muviri wevharuvhu. Ichi chinyorwa chine kuoma kwakasimba, yakanaka kudzvinyirira kuramba uye inogona kubata tembiricha yakakwira zvakanaka. Hazvizokanganisika zviri nyore pasi pemamiriro ekushanda akaomarara, mutengo unokwanisika uye hupenyu hwesevhisi hurefu, saka ndiyo inonyanya kufarirwa sarudzo yenguva dzose mavharuvhu eglobhu.

Ndeapi media yaanogona kubata? Chero midhiya yekudzivisa?

Inokodzera mvura yakachena, steam, mafuta anopisa, mhepo yakamanikidzwa, mafuta akareruka. Kwete yeasidhi yakasimba/alkali yakakwira-corrosion fluid; dzivisa zviri pakati nepakati nezvikamu zvihombe zvakasimba zvinokwenya kuvharika.

Sei uchisarudza vharuvhu yepasi panzvimbo yevharuvhu yegedhi remutsetse wemhepo?

Globe vharafu inotsigira inogadziriswa kuvhurwa kweiyo chaiyo throttling & kudzora kudzvinyirira. Gedhi vharuvhu rinongoshanda rakazara rakavhurika / rakazara kuvhara pasina kudzora basa. Globe valve ine chisimbiso chakasimba pasi pemhepo inopisa uye inodzivirira pombi yemvura sando.         

Mapoinzi akakosha ekuisa flange?

Yakachena flange yekuisa chisimbiso kumusoro kujekesa welding slag uye ngura; shandisa inofananidzwa GB graphite/PTFE gasket; simbisa mabhaudhi akaenzana zvakaenzana kudzivirira kubuda kweflange; usapfuure-torque kupwanya gasket.

Ko vharuvhu yepasi ine muganho wekumisa nzira?

Ehe. Isa uchitevera museve wekuyerera pane valve muviri (midhiya inoyerera kubva pasi pe diski kuenda pamusoro pe disc). Reverse mounting inokonzera kusaisa chisimbiso, kushanda nesimba uye backflow. Stem inofanira kuramba yakamira panguva yekuisa.
