Cov cim ntawm lub valveyog cov khoom tseem ceeb ntawm cov qauv engineering, tshwj xeeb tshaj yog hauvcov duab kos ntawm cov kav dej thiab cov cuab yeej siv (P&ID). Ntawm cov cim no, covlub cim ntawm lub valve npauj npaimsawv tawm rau nws txoj kev tsim tshwj xeeb thiab kev siv dav dav hauv kev lag luam. Tsab xov xwm no tshawb nrhiav qhov tseem ceeb ntawm lub cim npauj npaim valve, piv rau lwm cov cim valve zoo lilub cim tsis rov qab los, thiab qhia txog lub luag haujlwm ntawmTuam Tshoj npauj npaim valve manufacturers thiab cov neeg muag khoomhauv kev xa cov kev daws teeb meem zoo ntawm kev sib twtus nqi ntawm lub valve npauj npaim.
Lub cim ntawm lub valve npauj npaim yog dab tsi
Lublub cim ntawm lub valve npauj npaimyog ib daim duab kos yooj yim uas siv rau hauv cov duab kos engineering los qhia txog qhov muaj lub valve npauj npaim hauv lub raj xa dej. Feem ntau nws muaj ob txoj kab ntsug (sawv cev rau lub disc) sib tshuam ib txoj kab kab rov tav (lub yeeb nkab), tsim ib "npauj npaimcov duab no. Lub cim no pab cov engineers thiab cov kws kho tshuab kom paub sai sai txog cov hom valve thaum lub sijhawm tsim qauv, kev saib xyuas, lossis kev daws teeb meem.
Npauj npaim li qubnrov rau lawv txoj kev tsim qauv me me, kev ua haujlwm sai, thiab kev siv nyiaj tsim nyog. Lawv tswj kev ntws los ntawm kev tig lub disc 90 degrees, ua rau lawv zoo tagnrho rau cov kav dej loj hauv kev lag luam xws li kev kho dej, roj thiab roj av, thiab HVAC systems.
Cov Cim Qhia Txog Lub Valve: Lub Valve Npauj Npaim vs. Lub Valve Tsis Rov Qab Los
Kev nkag siab txog cov cim ntawm lub valve ua kom muaj qhov tseeb hauv kev tsim qauv. Nov yog kev sib piv ntawm ob lub cim tseem ceeb:
1. Lub Cim Npauj Npaim
- Sawv cev rau lub valve rotary ib feem plaub nrog lub disc voj voog.
- Kos ua ib txoj kab ntsug uas hla ib txoj kab yeeb nkab kab rov tav.
- Feem ntau muaj cim nrog "BV"los yog cov lus piav qhia ntxiv rau kev meej.
2. Lub Cim Tsis Rov Qab Los (Lub Cim Xyuas)
- Tsim los kom tsuas yog ntws mus rau hauv ib qho kev taw qhia xwb.
- Piav qhia ua lub taub hau xub taw rau hauv qhov kev taw qhia ntws uas tso cai, feem ntau nrog txoj kab diagonal lossis kaw nkhaus.
Txawm hais tias cov npauj npaim tswj kev coj thiab qhov ntim ntawm cov dej ntws, cov twj tso kua dej tsis rov qab tiv thaiv kev ntws rov qab. Ob lub cim no tseem ceeb rau kev tswj hwm kev ua haujlwm zoo thiab kev nyab xeeb ntawm lub kaw lus.
Vim Li Cas Los Ntawm Ib Qho Kev Txhim KhoChaw Tsim Khoom Siv Npauj Npaim Valvenyob rau hauv Suav teb
Tuam Tshoj tau tshwm sim los ua lub hauv paus thoob ntiaj teb rau kev tsim khoom siv valve, muab:
- Kev daws teeb meem uas pheej yig: Sib twtus nqi ntawm lub valve npauj npaimvim yog cov txheej txheem tsim khoom yooj yim thiab kev lag luam ntawm qhov ntsuas.
