Umgaqo wokukhetha ivalvu yeglobhu
Ivalvu yokuvala ibhekisa kwivalvu enenxalenye yokuvala (idiski) ehamba kumgca osembindini wesihlalo sevalvu. Ngokwale ndlela yokuhamba kwediski yevalvu, utshintsho lwesango lesihlalo sevalvu luhambelana nokubetha kwediski yevalvu. Ekubeni ukubetheka okanye ukuvala kwesiqu sevalvu solu hlobo lwevalvu kufutshane, kwaye kunomsebenzi othembekileyo wokunqunyulwa, kwaye ngenxa yokuba utshintsho lwesango lesihlalo sevalvu luhambelana ngqo nokubetha kwediski yevalvu, lufanelekile kakhulu ukulungiswa kokuhamba kwamanzi. Ke ngoko, olu hlobo lwevalvu lufanelekile kakhulu ukusetyenziswa njengesiciko sokuvala okanye sokulungisa kunye nokuqhobosha.

Umgaqo wokukhetha ivalvu yeglobhu ngulo:
1. Ivalvu yokumisa kufuneka isetyenziswe kumbhobho okanye kwisixhobo esinobushushu obuphezulu kunye nesixhobo soxinzelelo oluphezulu. Ezifana nezityalo zamandla ezishushu, izityalo zamandla enyukliya, imibhobho yobushushu obuphezulu kunye noxinzelelo oluphezulu lweenkqubo zepetrochemical.
2. Kwimibhobho engadingi ukumelana okungqongqo kwe-convection. Oko kukuthi, apho ukulahleka koxinzelelo kungaqwalaselwa.
3. Kwiivalvu ezincinci, iivalvu zenaliti, iivalvu zezixhobo, iivalvu zokuthatha iisampulu, iivalvu zokulinganisa uxinzelelo, njl.njl. zingasetyenziswa.
4. Kukho uhlengahlengiso lokuhamba okanye uhlengahlengiso loxinzelelo, kodwa ukuchaneka kohlengahlengiso akuphezulu, kwaye ububanzi bombhobho buncinci, njengombhobho onendlela eqhelekileyo ye-≤50mm, kufuneka ukhethwe.
5. Izichumisi ezincinci kunye nezichumisi ezinkulu kwimveliso yokwenziwa kwemizi-mveliso kufuneka zisebenzise iivalvu zeglobhu ezinee-angle zoxinzelelo oluphezulu okanye iivalvu zeglobhu ezinee-angle zoxinzelelo oluphezulu ze-PN160 kunye noxinzelelo oluqhelekileyo lwe-16MPa okanye i-PN320 kunye noxinzelelo oluqhelekileyo lwe-32MPa.
6. Kwiworkshop yokususa isiliconization yenkqubo ye-alumina Bayer kunye nemibhobho ethanda ukucolwa, kulula ukukhetha ivalvu yokumisa ukuhamba ngqo okanye ivalvu yokumisa ukuhamba ngqo kunye nomzimba wevalvu owahlulwe, isihlalo sevalvu sinokususwa, kunye nesibini sokutywina i-carbide efakwe isamente.
7. Kwiiprojekthi zokubonelela ngamanzi kunye nokufudumeza kulwakhiwo lwasezidolophini, imibhobho emincinci idlula ngokwesiqhelo, kwaye iivalvu zokumisa, iivalvu zokulinganisela okanye iivalvu zeplunger zinokukhethwa, njengemibhobho edlula ngokwesiqhelo ngaphantsi kwe-150mm.
