Tswj li qub thiab pneumatic li qub yog ob qho tib si tseem ceeb hauv cov kua thiab roj, tab sis lawv ua haujlwm sib txawv thiab ua haujlwm raws li cov qauv sib txawv. Ntawm no yog ib qho kev sib cais ntawm lawv qhov sib txawv:
1. Muaj nuj nqi:
Tswj Valve:Lub valve tswj tswj qhov ntws ntawm cov kua (kua lossis roj) los ntawm qhov sib txawv ntawm qhov ntws ntws. Cov kev cai no yog qhov tseem ceeb rau kev tswj tsis tau xws li siab, kub, thiab ntws tus nqi hauv cov txheej txheem kev lag luam. Tswj li qub yog siv los tswj cov ntsiab lus tshwj xeeb hauv cov txheej txheem los ntawm kev kho cov dej ntws raws li kev tawm tswv yim los ntawm cov sensors.
Pneumatic Valve:Lub pneumatic valve tshwj xeeb tswj cov ntws ntawm compressed cua los yog gases nyob rau hauv ib tug pneumatic system. Nws lub luag haujlwm tseem ceeb yog coj los yog tso tseg cov cua ntws mus rau ntau yam ntawm lub cev, xws li lub tog raj kheej, cov khoom siv hluav taws xob, lossis cov cuab yeej. Pneumatic li qub yog qhov tseem ceeb rau kev tswj lub zog thiab kev ua haujlwm ntawm cov tshuab siv los ntawm cov cua compressed.
2. Kev ua haujlwm:
Tswj Valve:Ua haujlwm los ntawm kev kho qhov chaw ntawm lub valve (xws li lub ntsaws, pob, lossis npauj npaim) kom tswj tau tus nqi ntws. Txoj haujlwm ntawm lub valve feem ntau yog tswj los ntawm lub teeb liab los ntawm kev tswj hwm, uas tuaj yeem yog phau ntawv, hluav taws xob, pneumatic, lossis digital. Tswj li qub tuaj yeem ua haujlwm tsis tu ncua kom kho qhov ntws.
Pneumatic Valve:Ua haujlwm los ntawm kev tswj cov ntws ntawm compressed cua los ntawm cov chaw nres nkoj. Pneumatic li qub tuaj yeem yooj yim rau / tawm li qub lossis ntau txoj haujlwm ntau li qub. Lawv feem ntau siv solenoids, phau ntawv levers, lossis cov tshuab tsav dav hlau los tswj lawv txoj haujlwm thiab tswj cov cua ntws. Pneumatic li qub feem ntau muaj tsawg theem ntawm kev tswj piv rau cov tswj li qub.
3. Hom:
Tswj Valve:Xws li ntau hom xws li:
Rooj vag Valves:Siv rau kev tswj / tawm nrog kev poob siab tsawg.
Pob Valves:Muab kev tswj xyuas meej nrog lub voj voog kaw.
Npauj Npaim Valves:Muab kev tswj cov dej ntws nrog lub rotating disk.
Globe Valves:Siv rau qhov tseeb throttling nrog ib qho kev tawm suab ntawm lub valve ntsaws.
Pneumatic Valve:Xws li hom xws li:
Solenoid li qub:Hluav taws xob ua haujlwm los tswj cov cua ntws.
Manual Valves:Ua haujlwm ntawm tes kom ncaj qha airflow.
Directional Control Valves:Tswj cov kev taw qhia ntawm huab cua ntws (xws li, 3/2 lossis 5/2 li qub).
Siab Regulating Valves:Ua kom lub siab sib xws hauv lub pneumatic system.
4. Daim ntawv thov:
Tswj Valve:Siv rau hauv cov txheej txheem kev lag luam, HVAC systems, kev ua tshuaj lom neeg, kev kho dej, thiab txhua daim ntawv thov uas xav tau kev tswj xyuas cov kua dej kom meej. Lawv yog ib qho tseem ceeb rau kev tswj xyuas kev ua haujlwm zoo thiab kev nyab xeeb hauv cov txheej txheem nyuaj.
Pneumatic Valve:Siv nyob rau hauv pneumatic systems rau automation thiab machinery tswj, xws li nyob rau hauv manufacturing, robotics, thiab industrial cov khoom. Lawv yog qhov tseem ceeb rau kev tswj xyuas kev ua haujlwm ntawm pneumatic lub tog raj kheej thiab cov actuators.
5. Tawm tswv yim thiab tswj:
Tswj Valve:Feem ntau ua ke nrog lub tswv yim tswj qhov system. Sensors ntsuas cov txheej txheem sib txawv (xws li, siab, ntws tus nqi) thiab xa cov teeb liab mus rau tus tswj, uas kho lub valve txoj hauj lwm kom tswj tau qhov xav tau teeb tsa.
Pneumatic Valve:Feem ntau tswj manually lossis nrog cov teeb liab hluav taws xob. Pneumatic systems yuav siv tau yooj yim rau / tawm ntawm lwm yam los yog ntau sophisticated ntau txoj hauj lwm tswj, tab sis lawv feem ntau tsis muaj lub nruam tawm tswv yim mechanisms pom nyob rau hauv kev tswj li qub.
6. Kev nyuaj siab:
Tswj Valve:Muaj peev xwm ua tau ntau dua vim qhov xav tau rau kev tswj xyuas meej thiab kev koom ua ke nrog cov txheej txheem tswj cov txheej txheem. Lawv feem ntau xav tau calibration thiab hloov kho kom ntseeg tau tias kev ua haujlwm raug.
Pneumatic Valve:Feem ntau yooj yim hauv kev tsim thiab kev ua haujlwm, tsom mus rau kev ncaj qha airflow es tsis tu ncua modulating nws.
