Hauv thaj tsam ntawm kev tswj cov kua dej, cov li qub ua lub luag haujlwm tseem ceeb hauv kev tswj lub siab, ntws, thiab kev taw qhia. Ntawm ntau hom li qub, pilot ua haujlwm li qub (POVs) thiab nyem li qub (RVs) sawv tawm raws li qhov tseem ceeb ntawm kev ua kom muaj kev nyab xeeb thiab kev ua haujlwm zoo. Txawm hais tias ob qho tib si ua haujlwm rau lub hom phiaj ntawm kev tswj kev siab, lawv txawv ntawm lawv cov txheej txheem kev khiav hauj lwm thiab kev siv.

Pilot Operated Valves: Ib txoj hauv kev meej thiab tswj tau

Pilot ua haujlwm li qub, tseem hu ua qhov sib npaug li qub, ntiav ib tus kws tsav dav hlau los tswj lub ntsiab valve loj dua. Qhov kev tsim ob theem no muaj ntau yam zoo:

Precise Pressure Regulation: POVs muab qhov tshwj xeeb ntawm kev tswj siab, ua rau lawv zoo tagnrho rau cov ntawv thov uas qhov kev tswj xyuas qhov tseeb yog qhov tseem ceeb.

Txo Hnav thiab Tear: Tus tsav valve tiv thaiv lub ntsiab valve los ntawm kev raug ncaj qha rau lub zog siab, txo qis hnav thiab tsim kua muag thiab txuas ntxiv lub neej ntev.

Superior Sealing: POVs tuav lub kaw ntom nti txawm tias qhov system siab mus txog qhov teeb tsa siab, tiv thaiv kev xau thiab ua kom muaj kev ncaj ncees.

Versatility nyob rau hauv daim ntawv thov: POVs muaj ntau yam thiab muaj peev xwm tswj tau ntau yam kev kub ntxhov, kua dej, thiab kev ua haujlwm.

Relief Valves: Tiv thaiv cov txheej txheem los ntawm kev kub siab dhau

Relief li qub, tseem hu ua kev ruaj ntseg li qub, ua haujlwm ruaj ntseg rau cov kua dej, tiv thaiv overpressurization thiab tej yam kev phom sij. Lawv khiav lag luam los ntawm kev qhib thaum lub kaw lus siab tshaj qhov kev txiav txim siab predetermined, tso siab dhau los tiv thaiv lub system.

Rapid Pressure Relief: RVs muab kev pab sai sai, tiv thaiv cov tshuab los ntawm kev kub siab sai.

Simplicity of Design: RVs yog qhov yooj yim hauv kev tsim, ua rau lawv yooj yim rau nruab, tswj, thiab daws teeb meem.

Kev daws teeb meem raug nqi: RVs feem ntau raug nqi ntau dua piv rau POVs.

Xaiv qhov zoo Valve rau koj xav tau

Kev xaiv ntawm tus tsav ua haujlwm valve thiab lub valve nyem yog nyob ntawm daim ntawv thov tshwj xeeb thiab kev ua tau zoo. Nov yog cov ntsiab lus los qhia koj qhov kev txiav txim siab:

Rau qhov kev tswj xyuas qhov siab thiab cov ntawv thov uas yuav tsum tau xau tsawg, POVs yog qhov kev xaiv.

Rau kev tiv thaiv overpressure thiab ceev ceev nyem nyob rau hauv cov nqi-sensitive daim ntaub ntawv, RVs yog zoo tagnrho tov.
