Valve tsav txoj kev tuaj yeem muab faib ua phau ntawv tsav tsheb, kov lub log hom, lub caij nplooj ntoo hlav hom, hluav taws xob tsav, hom electromagnetic, hom tsav, thiab pneumatic tsav. Cov txheej txheem tsav valve feem ntau yog phau ntawv, pneumatic, hydraulic, thiab hluav taws xob. Cov txheej txheem tsav sib txawv sib haum rau ntau yam kev ua haujlwm.
Phau ntawv valve
Phau ntawv li qub ua haujlwm siv txoj kev tsav yooj yim tshaj plaws: phau ntawv. Daim ntawv no suav nrog kev tsav tsheb ncaj qha los ntawm lub log, tuav, lossis cov ciaj ntswj thiab tsav los ntawm kev sib kis ntawm lub tshuab turbine.
Thaum lub valve pib torque yog qhov txaus, kev ua haujlwm zoo tib yam lossis kev ua haujlwm ntawm tes yog qhov nyuaj thiab ua haujlwm, thiab nws tuaj yeem tsav los ntawm iav lossis turbine kis tau tus mob. Iav kis tau muab faib ua spur iav, cylindrical iav kis tau tus mob, thiab bevel iav kis tau tus mob. Iav kis tau tus mob me me piv thiab haum rau lub rooj vag thiab lub ntiaj teb li qub. Turbine kis tau tus mob muaj qhov txo qis loj thiab zoo tagnrho rau npauj npaim thiab pob li qub.
Pneumatic thiab hydraulic li qub
Pneumatic thiab hydraulic li qub tau ua ke vim tias lawv muaj ntau qhov sib xws. Ob daim ntawv tsav tsheb, pneumatic thiab hydraulic, siv huab cua, dej, los yog roj ntawm ib lub zog tshwj xeeb raws li lub zog thiab lub tog raj kheej lossis hydraulic cylinders los ua piston txav los tsav lub valve kom qhib thiab kaw.
Feem ntau, cov khoom siv pneumatic 'huab cua siab tsawg dua 0.8MPa, thiab cov khoom siv hydraulic' dej lossis roj siab yog 2.5MPa ~ 25MPa. Ob lub pneumatic thiab hydraulic tsav khoom haum rau npauj npaim, pob, thiab ntsaws li qub. Qhov txawv yog tias cov cuab yeej hydraulic tsav tsheb yog qhov tseem ceeb dua thiab tsim nyog rau kev tsav tsheb loj-ntev li qub.
Hluav taws xob li qub
Hluav taws xob li qub yog tsav los ntawm hluav taws xob thiab kuj yog ib qho ntawm feem ntau siv valve-tsav txoj kev. Qhov zoo ntawm hluav taws xob li qub yog raws li nram no:
1. Ceev qhib thiab kaw thiab lub sijhawm qhib thiab kaw ntawm lub valve yog txo qis.
2. Nws tuaj yeem txo qhov kev ua haujlwm ntawm cov neeg ua haujlwm valve, tshwj xeeb tshaj yog rau lub siab-siab thiab loj-inch li qub.
3. Lub tshuab hluav taws xob feem ntau tau teeb tsa qhov chaw ua haujlwm tsis tuaj yeem lossis cov neeg ua haujlwm nyuaj rau kev mus kom ze (qhov siab siab lossis qhov chaw ua haujlwm txaus ntshai). Lawv tuaj yeem ua haujlwm nyob deb, thiab qhov siab ntawm lub installation yog txwv, uas tuaj yeem ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm.
4. Nws yog qhov tsim nyog rau lub automation ntawm tag nrho cov system.
5. Cov khoom siv hluav taws xob tuaj yeem siv tau ntau dua li cov khoom siv roj thiab kua, thiab cov xaim tso thiab kev saib xyuas yog yooj yim dua li compressed cua thiab hydraulic pipelines. Tau kawg, hluav taws xob li qub kuj muaj qee qhov tsis zoo. Lawv cov qauv yog qhov nyuaj dua rau kev siv nyob rau hauv qhov chaw ntub dej sab nraud, thiab kev kho tawg-pov thawj kuj tseem xav tau rau cov xov xwm tawg.
