Umgaqo wokukhetha wevalve yeglowubhu
Ivalve yokuvala ibhekisa kwivalve enxalenye yayo yokuvala (idiski) ihamba kumgca osembindini wesitulo sevalve.Ngokwale fomu yentshukumo yediski yevalve, ukutshintshwa kwe-valve seat port ilingana ne-valve disc stroke.Ekubeni ukuvulwa okanye ukuvala i-valve yesikhondo solu hlobo lwevalve lufutshane, kwaye inomsebenzi othembekileyo wokusika, kwaye ngenxa yokuba utshintsho lwesigxina sesihlalo sevalve luhambelana ngokuthe ngqo kwi-stroke ye-valve disc. , ifanelekile kakhulu ukulungiswa kokuhamba.Ngoko ke, olu hlobo lwevalve lufanelekile kakhulu ukuba lusetyenziswe njengento yokuvala okanye ukulungiswa kunye ne-throttling.

Umgaqo wokukhetha wevalve yeglowubhu ngulo:
1. Ivalve yokumisa kufuneka isetyenziswe kumbhobho okanye isixhobo sobushushu obuphezulu kunye noxinzelelo oluphakathi.Okufana nezityalo zamandla ashushu, amaziko ombane enyukliya, ubushushu obuphezulu kunye nemibhobho yoxinzelelo oluphezulu lweenkqubo zepetrochemical.
2. Kwimibhobho engadingi ukuchasana ngokungqongqo kwi-convection.Oko kukuthi, apho ukulahlekelwa kwengcinezelo kungaqwalaselwa.
3. Iivalve ezincinci, iivalve zenaliti, iivalve zesixhobo, iivalve zesampula, iivalve zokulinganisa uxinzelelo, njl.
4. Kukho ukulungelelaniswa kokuhamba okanye ukulungiswa koxinzelelo, kodwa ukuchaneka kokulungelelaniswa akuphezulu, kwaye ububanzi bombhobho buncinci, njengombhobho kunye ne-nominal passage ye-≤50mm, kufuneka ikhethwe.
5. Izichumisi ezincinci kunye nezichumisi ezinkulu kwimveliso yokwenziwa kwimizi-mveliso kufuneka zisebenzise iivalvu zeglobe ze-angle yoxinzelelo oluphezulu okanye iivalvu zeglobhu ezinoxinzelelo oluphezulu lwe-PN160 kunye noxinzelelo lwegama le-16MPa okanye i-PN320 kunye noxinzelelo lwe-32MPa.
6. Kwi-workshop ye-desiliconization yenkqubo ye-alumina ye-Bayer kunye nemibhobho ethandwa kakhulu kwi-coking, kulula ukukhetha i-valve yokumisa ukuhamba ngokuthe ngqo okanye i-valve yokumisa ukuhamba ngokuthe ngqo kunye nomzimba we-valve owahlukileyo, isihlalo sevalve sinokususwa, kunye nesitywina sokutywina se-carbide esamente.
7. Kunikezelo lwamanzi kunye neeprojekthi zokufudumeza kulwakhiwo lwasezidolophini, imibhobho emincinci idlula ngokwegama, kwaye iivalvu zokumisa, iivalvu zebhalansi okanye iivalvu zeplunger zingakhethwa, njengemibhobho egqithwe ngaphantsi kwe-150mm ngegama.
I-Nortech ngomnye wabavelisi abakhokelayo bevalvu yeshishini e-China kunye nesiqinisekiso somgangatho we-ISO9001.
Iimveliso eziphambili:Ivalve yebhabhathane,Ivalve yeBhola,Ivalve yeSango,Jonga iValve,Iglobhu iVavlve,I-Y-Strainers,Iacurator yoMbane,I-Pneumatic Acurators .
