3 txoj kev ntsaws valveyog ib qho kaw los yog plunger zoo li lub pob valve, los ntawm kev tig 90 degrees los ua qhov chaw nres nkoj ntawm lub valve ntsaws thiab lub valve lub cev ntawm tib yam los yog cais, qhib lossis kaw lub valve.Lub ntsaws ntawm lub ntsaws valve yuav yog cylindrical los yog conical nyob rau hauv cov duab.Nyob rau hauv cylindrical plugs, channels feem ntau yog rectangular;Nyob rau hauv lub tapered plug, lub channel yog trapezoidal.Cov duab no ua rau cov qauv ntawm lub ntsaws valve sib zog, tab sis tib lub sijhawm tsim ib qho kev poob.Lub ntsaws valve yog qhov tsim nyog tshaj plaws rau kev txiav thiab txuas nruab nrab thiab kev hloov pauv, tab sis nyob ntawm qhov xwm txheej ntawm daim ntawv thov thiab kev yaig tsis kam ntawm qhov sealing nto, qee zaum nws kuj tuaj yeem siv rau throttling.Vim tias qhov txav ntawm qhov sib khi ntawm lub ntsaws valve muaj cov nyhuv so, thiab thaum qhib tag nrho, nws tuaj yeem tiv thaiv kev sib cuag nrog qhov nruab nrab ntws, yog li nws kuj tuaj yeem siv rau nruab nrab nrog cov khoom raug tshem tawm.Lwm qhov tseem ceeb ntawm lub ntsaws valve yog nws qhov yooj yim ntawm kev hloov mus rau ntau txoj kev tsim, kom lub valve tuaj yeem muaj ob, peb, lossis plaub qhov sib txawv ntws.Qhov no ua kom yooj yim rau kev tsim cov kav dej, txo cov kev siv valve, thiab txo cov khoom siv hauv cov khoom siv.
NORTECHis ib qho ntawm cov thawj coj hauv Suav teb 3 txoj kev ntsaws valve Chaw tsim tshuaj paus & tsum.
