Dab tsi yog cov hlau nplaum valve thiab nws ua haujlwm li cas?

Hlau nplaum Valveyog cov khoom siv lag luam uas siv tswj hluav taws xob. Nws yog tsuas yog siv los tswj cov khoom siv tshuab hluav taws xob ntawm cov kua thiab yog rau cov neeg ua yeeb yam. Nws tswj hwm cov kev coj ua, ntws, nrawm nrawm thiab lwm yam ntawm cov kua dej los ntawm kev siv hluav taws xob, thiab yog siv dav hauv ntau cov khoom siv tswj thiab cov khoom siv.

Ua haujlwm ua haujlwm ntawm cov hlau nplaum valve

Cov Hlau nplaum feem ntau yog tsim ntawm lub cev valve, hluav taws xob cher, hlau tub ntxhais thiab armature. Thaum lub kauj hauv hluav taws xob tau energized, uas sib zog sib nqus yuav tsim tawm, uas yuav ua rau lub caj npab kom txav, yog li qhib lossis kaw cov dej channel. Thaum lub xov hluav taws xob siv hluav taws xob?

Kev faib tawm cov hlau nplaum li qub

Cov hlau nplaum li qub tuaj yeem faib ua ob pawg:

Direct-ua yeeb yam hlau nplaum valve: Thaum lub kauj yog energized, lub valve yog qhib ncaj qha lossis kaw.

Tus kws tsav dav hlau hluav taws xob valve: Thaum energized, lub pob hluav taws xob qhib qhib lossis kaw raws li qhov loj me ntawm qhov siab sib txawv.

Ntxiv rau, cov hlau nplaum li qub tseem muaj ob hom: nquag kaw (NC) thiab ib txwm qhib (tsis muaj):

Li qub kaw hlau nplaum valve (xc): lub valve core core yog kaw thaum lub chev tsis energized, thiab qhib thaum energized.

Li qub qhib cov hlau nplaum valve (tsis muaj): lub valve core qhib thaum lub kauj yog de-energized, thiab kaw thaum muaj zog.

Daim Ntawv Thov Kev Ua Si ntawm Cov Hlau nplaum li qub

Hlau nplaum li qubtau siv dav hauv ntau cov kev tswj hwm cov tshuab thiab cov khoom siv kho txhua yam, xws li:

HYDRAULIC SYSTEM: Tswj cov kev taw qhia thiab ntws ntawm cov roj Hydraulic.

Pneumatic system: Tswj cov thiab tawm ntawm cov roj.

Cov kab ke tawm: siv rau kev thauj khoom thiab thau khoom, kho kom haum, kho dua tshiab, thiab lwm yam.
