LUB ROOJ HAUJ LWM THIAB REPLACEABLE VALVE INTERNAL PARTSuas tuaj nyob rau hauv kev sib cuag nrog cov ntws nruab nrab yog collectively hu uaVALVE TRIM. Cov khoom no muaj xws li lub rooj zaum (s), disc, caj pas, spacers, cov lus qhia, bushings, thiab sab hauv springs. Lub valve lub cev, lub kaus mom, ntim khoom, thiab lwm yam uas tseem tuaj yeem cuam tshuam nrog qhov nruab nrab ntws tsis suav tias yog lub valve trim.

Lub Valve txoj kev ua tau zoo yog txiav txim siab los ntawm lub disk thiab lub rooj sib tham thiab kev sib raug zoo ntawm qhov chaw disk rau lub rooj. Vim yog lub trim, yooj yim txav thiab khiav tswj tau. Nyob rau hauv rotational motion trim designs, lub disk slides ze ze ntawm lub rooj zaum los tsim ib tug hloov nyob rau hauv txaus qhib. Nyob rau hauv linear motion trim designs, lub disk nqa perpendicularly deb ntawm lub rooj thiaj li hais tias ib tug annular orifice tshwm.

Valve trim qhov chaw tuaj yeem tsim los ntawm ntau yam khoom siv vim tias muaj cov khoom sib txawv uas xav tau los tiv thaiv kev sib txawv thiab cov xwm txheej. Bushings thiab packing caj pas tsis muaj tib lub zog thiab tej yam kev mob xws li lub valve disc thiab lub rooj zaum.

Flow-medium zog, tshuaj muaj pes tsawg leeg, siab, kub, ntws tus nqi, tshaj tawm thiab viscosity yog ib co ntawm cov kev txiav txim siab tseem ceeb hauv kev xaiv cov khoom tsim nyog. Trim cov ntaub ntawv tej zaum yuav los yog tsis yog cov khoom tib yam li lub valve lub cev los yog lub kaus mom.

API muaj cov txheej txheem txiav cov ntaub ntawv los ntawm kev muab tus lej tshwj xeeb rau txhua pawg ntawm cov khoom siv.
