ubuchule Ukukhetha valve

1, ivelufa check (aetv ndlela-Omnye umba): esebenzayo ngokubanzi kumajelo nyulu, kungekhona ngenxa equlethe amasuntswana eziluqilima kwaye viscosity medium.

2, kulandela ivalve ephantsi-uxinzelelo DN50mm (aetv ndlela-Omnye umba):, kufuneka usebenzise ibhabhathane wevalufa, khangela nokufakelwa uvalo lift nkqo ujonge valve; Kuba DN mkhulu 200mm, ngaphantsi kwe-1200mm of ephantsi koxinzelelo check wevalufa, non-esingajijekiyo kufuneka zikhethwe kwi athwale ukulenza; ngokuba DN mkhulu kuno-50mm, ngaphantsi kwe-2000mm of ephantsi koxinzelelo check wevalufa, ibhabhathane nokufakelwa uvalo kufuneka basebenzise kwemithambo ngetshekhi.

3, uvalo vana esifanelekileyo lula ukuvelisa isando amanzi yombhobho, i inwebu yayinokususwa medium emantla iveliswa xa ihamile amanzi, kodwa iqondo lobushushu kunye noxinzelelo Imida, ngokubanzi bushushu kwi ezisendleleni xi eliphantsi.
