Kwiworkshop yeJinbin, inani elikhulu leiivalvu zeglowubhuziphantsi kohlolo lokugqibela. Ngokweemfuno zabathengi, ubungakanani babo buqala kwi-DN25 ukuya kwi-DN200.

Njengevalve eqhelekileyo, ivalve yeglowubhu inezi mpawu zilandelayo:

I-1.Umsebenzi wokutywina ogqwesileyo: Isakhiwo sokutywinwa esingundoqo sibonisa ukulingana okuqinileyo phakathi kwe-disc valve kunye nesihlalo sevalve. Xa ivaliwe, i-disc yevalve icinezela isihlalo sevalve phantsi koxinzelelo, ifezekisa ukusika okuqinileyo. Ilungele izicelo apho ukuvuza okuphakathi kufuneka kuthintelwe (njengemibhobho yegesi kunye nomphunga).

I-2.Ukusebenza kokulawula okugqwesileyo: I-disc ye-valve iphakama kwaye iwela kunye ne-axis ye-valve stem, kwaye izinga lokuhamba lingalungiswa ngokuchanekileyo ngokulawula i-degree yokuvula. Isantya sokuhamba sitshintsha ngokucokisekileyo ukusuka ekuvuleni ngokupheleleyo ukuya kukuvalwa ngokupheleleyo, okwenza kube lula kwiimeko ezifuna ukulawulwa kokuhamba kakuhle (njengokulungiswa kweqondo lokushisa kwiinkqubo zokufudumeza).

I-3.Ukuchasana nokuhamba okukhulu: I-medium idinga ukujika kunye nokuphuma emva kokudlula kwisihlalo se-valve, kunye nendlela ephazamisayo. Ilahleko yoxinzelelo inkulu kuneevalve ezithe ngqo ezifana neevalvu zesango. Ngoko ke, ayifanelekanga kwimibhobho ehamba phambili kunye neemfuno eziphantsi zokumelana (njengombhobho oyintloko wokuhambisa amanzi).

I-4.Ukufakwa kwe-Directional: Kufuneka kufakwe ngokuhambelana nomgaqo "ophantsi, ophezulu" (i-medium flows isuka ngaphantsi kwe-valve disc), iqinisekisa ukuba i-disc ye-valve incediswa ukutywinwa ngoxinzelelo oluphakathi xa ivaliwe, kwaye umsebenzi awunzima. Ukuyifakela ngasemva kuya kukhokelela ekungaphumeleli kwetywina kunye nokusebenza kanzima.

I-5.Uluhlu olubanzi lweendaba ezisebenzayo: Ingasetyenziselwa imidiya ecocekileyo njengamanzi, i-steam, iimveliso zeoli, kunye negesi, kodwa ayifanelekanga kwi-high-viscosity okanye i-granular media (njengoko inokugqoka ngokulula indawo yokutywina kwaye yonakalise ukusebenza kokutywinwa).

Ngokusekwe kwezi mpawu, iivalve zokumisa zisetyenziswa ngokubanzi kwiimeko ezifuna ukuvalwa okuqinileyo kunye nommiselo ochanekileyo:

1. Ubonelelo lwamanzi kunye nenkqubo yokuhambisa amanzi: Njengevalve yokulawula iglowubhu kwimibhobho yesebe, iyayinqumla okanye ilawule umthamo wamanzi ukuqinisekisa ulawulo lwendawo yothungelwano lwemibhobho.

2. Isixokelelwano somphunga: Sika unikezelo lomphunga okanye ulawule izinga lokuhamba kwimibhobho yomphunga kwishishini, kwaye usebenzise ipropathi yokutywina ukuthintela ukuvuza komphunga kunye nokulahleka kwamandla.

3. Imboni yePetrochemical: Xa uhambisa ioli ekrwada, i-solvents kunye nezinye imidiya, isantya sokuhamba silawulwa ngokulungelelanisa idigri yokuvula ukuhlangabezana neemfuno zokutya kwesixhobo sokusabela.

4. Iinkqubo zokufudumeza kunye ne-air conditioning: Ukulawula ukuhamba kwamanzi ashushu okanye ifriji ukuze ufezekise ulawulo oluchanekileyo lobushushu begumbi kunye nokuphucula ukusebenza kakuhle kokusetyenziswa kwamandla.

Igesi kunye nemibhobho yomoya ecinezelekileyo: Njengevalve yokuvala ukhuseleko, ivala ngokukhawuleza ngexesha lokugcinwa okanye iimpazamo zokuthintela ukuvuza okuphakathi kunye neengozi zokhuseleko ezinokubakho.

Ngeengenelo zokutywinwa okuthembekileyo kunye nommiselo oguquguqukayo, ivalve yeglowubhu ejingiwe iye yaba yinxalenye engundoqo kwiinkqubo zemibhobho edibanisa imisebenzi yokusika kunye nokulawula. Ayinakuthathelwa indawo ngakumbi kwiimeko ezinobubanzi obuphakathi nobuncinci kunye neemfuno eziphezulu zokutywinwa kunye nolawulo. (Ixabiso leGlobe Valve)
