Ubume bevalve yokukhulula

Ivalve yokunceda yenziwe ngumzimba wevalvu, i-spool, isiphethu kunye nesixhobo sokulawula. Phakathi kwabo, umzimba wevalve yeyona ndawo iphambili yevalve yokunceda
Idla ngokuba yintsimbi okanye i-aluminiyam. I-spool yivalve ebekwe emzimbeni, edla ngokwenziwa ngentsimbi okanye ubhedu. dlala
Intwasahlobo isetyenziselwa ukulungelelanisa uxinzelelo lokuvula kunye nokuvala uxinzelelo lwe-spool. Isixhobo esilawulayo sisetyenziselwa ukulungelelanisa ukulinganiswa kwentwasahlobo
Ukunyanzeliswa, okuchaphazela uxinzelelo lokuvala lwe-spool.
Ngexesha lokusebenza kwevalve yoncedo, ulwelo luqukuqela lungene kumzimba wevalvu ukusuka kwindawo yokungena kwaye luphume ngomsantsa phakathi kwespool.
Xa uxinzelelo ludlula ixabiso lokusetha kwangaphambili, i-spool iya kuvula ngokuzenzekelayo, kwaye uxinzelelo olungaphaya kwexabiso lokusetha kwangaphambili luya kukhutshwa nge-port yokuphuphuma. Dang Cinezela
Xa amandla awela ngaphantsi kwexabiso elisetyenzisiweyo, i-spool iya kuvala ngokuzenzekelayo.
Umgaqo osebenzayo wevalve yokunceda
Xa ioli ye-hydraulic kwinkqubo igeleza kwivalve yokunceda, isantya kunye nesantya sokuhamba kweoli ye-hydraulic ilawulwa yi-spool.
. Ukuba uxinzelelo lweoyile ye-hydraulic luphezulu kunoxinzelelo lokuvula lwe-spool, i-spool iya kuvula ngokuzenzekelayo, kwaye ukuhamba kweoli ye-hydraulic ngaphaya kwexabiso lokuseta kwangaphambili liya kukhutshwa nge-port ephuphumayo. Ukuba i-oyile ye-hydraulic iphantsi kunoxinzelelo lokuvala i-spool, i-spool ivala ngokuzenzekelayo, ukukhusela ukuvulwa kwe-port ephuphumayo. Ngoko ke, ukuyila kunye nokulungelelaniswa koxinzelelo lokuvula kunye nokuvala uxinzelelo lwe-spool kubaluleke kakhulu, okuya kuchaphazela ukusebenza kokusebenza kunye noxinzelelo oluphezulu lwe-valve yokunceda.
