4. Qhib lub npov npog thiab txuas cov hlua hlau ntawm cov kab txuas rau lub davhlau ya nyob twg raws li kev tswj hluav taws xob thaiv daim duab.
5. Tig lub tes ntsaws kom ua lub valve ntawm kwv yees li 50% qhib txoj haujlwm, tig rau lub zog thiab xyuas seb lub teeb taw qhia ntawm lub teeb hluav taws xob tswj" ntawm" thiab" tawm" lub thawv khawm yog nyob rau hauv txoj kab nrog cov kev taw qhia ntawm kev sib hloov ntawm lub valve *. Yog tias tsis yog, theem ua ntu zus ntawm lub zog hluav taws xob yuav tsum kho kom nws nyab xeeb.
Lub tshuab hluav taws xob valve siv nyob rau hauv kev sib txuas nrog 90 ° tig lub npauj npaim li qub, pob li qub, ntsaws li qub thiab lwm yam khoom siv sib xws. Nws yog sib phim nrog lub pob txha caj qaum los tsim hluav taws xob valve, uas yog siv los tsav lub qhov qhib thiab kaw ntawm lub pob valve. Cov cuab yeej tuaj yeem paub cov chaw taws teeb tswj ntawm lub valve. Nws kuj tseem tuaj yeem ua haujlwm ntawm tus kheej rau ntawm qhov chaw. Cov khoom lag luam no tau siv dav hauv cov chaw nres tsheb fais fab, petrochemicals, dej thiab dej ntws, zaub mov, textile, tshuaj, dej txuag dej engineering, txua nkoj, tsim hluav taws xob hauv nroog, steel thiab cov lag luam thee uas siv cov raj xa dej.
