DIDNLIK kos valve yog qhov yooj yim tshaj plaws ntawm kev tswj lub valve siv hauv cov tshuab hydraulic. Kos li qub tso tseg cov dej ntws hauv ib qho kev taw qhia thiab tso cai rau cov dej ntws tawm hauv qhov sib txawv. Lawv kuj tseem hu ua non-return valves. Kos li qub yuav siv tau ua prefill li qub, bypass li qub, pre-tensioning los yog tiv thaiv hydraulic Cheebtsam tiv thaiv siab surges.
Feem ntau cov tshev valve yog lub caij nplooj ntoos hlav-loaded thiab siv lub pob lossis phaj los kaw qhov ntws hauv ib qho kev taw qhia. Check li qub yog tsim los nrog cov rooj zaum thiab yog li muaj peev xwm cais cov circuits uas tsis muaj qhov to. Cov pob, daim hlau, poppets lossis poppets nrog cov ntsaws ruaj ruaj yog siv los ua cov khoom sib cais.
Muaj ib hom kev kos valve tshwj xeeb uas tiv thaiv pistons lossis lub tog raj kheej plungers los ntawm kev nqis los thiab ua rau muaj xwm txheej. Qhov no yog hu ua kab rupture valve. Thaum cov kab ruptures, cov ntws los ntawm txoj kab rupture valve nce ntau, ua rau muaj kev poob siab ntxiv. Qhov no nyob rau hauv lem tsim ib tug muaj zog quab yuam ntawm lub pob, uas yuav kaw tam sim ntawd.
Lwm yam tshwj xeeb ntawm cov tshev li qub yog cov kws tsav dav hlau ua haujlwm thiab cov khoom siv hluav taws xob. Ib tug tsav-ua haujlwm check valve tso cai ntws nyob rau hauv ob qho tib si kev taw qhia los ntawm daim ntawv thov ntawm ib tug sab nraud pilot siab teeb liab. Lub shuttle valve tso cai pub dawb khiav ntawm lub siab tshaj plaws kev khiav hauj lwm siab.
