Yuav ua li cas paub qhov txawv ntawm cov pob hauv qab pob valve thiab trunnion pob valve

Qauv nta

1. Pob rooj sib txuas

Ntab pob lub pob valve: Lub pob ntab Thaum lub valve raug kaw, qhov nruab nrab lub siab thawb lub pob mus rau Outlet Valve, tsim lub foob.

Pob zeb ruaj ruaj: lub pob yog tsau rau sab saud thiab qis dua valve stems. Lub pob tsuas tuaj yeem tig tau txog lub axis ntawm lub valve qia thiab tsis tuaj yeem txav dawb huv ntawm lub cev.

2. Valve qia qauv

Ntab pob pob valve: Feem ntau, tsuas yog qis dua valve qia txuas nrog lub pob. Lub pob zeb sab sauv qis qia tsuas yog kis los ntawm lub zog torque thiab tsis ncaj qha tsau rau pob.

Lub pob ntim pob hluav taws xob: ob qho tib si sab sauv thiab qis dua valve ci yog txuas rau lub pob, txwv nws lub zog mus hloov.

Ua Haujlwm Cov Ntsiab Cai

1. FORTING LUB Xas

Ntab pob pob valve: Thaum kaw, nruab nrab lub siab thawb lub pob mus rau lub pob hluav taws xob hauv lub pob thiab lub rooj zaum. Qhov siab dua ntawm qhov nruab nrab siab, qhov zoo dua cov nyhuv seading. Ntawm qis lossis tsis muaj xov xwm siab, lub pob yuav tsis haum nruj nreem tiv thaiv lub rooj valve vim nws tus kheej hnyav, cuam tshuam kev sib khi ua haujlwm.

Trung pob valve: ib lub foob nruj ntawm lub pob thiab lub rooj zaum tau tiav los ntawm preload ntawm lub pob thiab rooj zaum, txuas nrog kev sib kis ntawm lub valve qia. Txawm hais tias ntawm kev tshaj xov xwm siab, nws kev sib khi ua tau zoo tseem cuam tshuam nrog qhov ruaj khov thiab tsis cuam tshuam los ntawm kev tshaj xov xwm kev hloov pauv.

2. Torque kis

Floating pob valve: Torque yog feem ntau kis tau rau lub pob ntawm qis qia, nrog lub qia sab saud muab kev kis tus mob. Thaum lub sijhawm qhib thiab kaw cov txheej txheem, lub pob yog raug rau cov rog nyuaj, muaj feem cuam tshuam los ntawm ntau qhov kev sib txhuam cov kev sib txhuam thiab kev sib txhuam.

Trung pob valve: Torque yog tus tseem kis tau rau lub pob sab saud thiab qis dua cov rog sib hloov, txhawb nqa lub sijhawm ntev ntev.

Kev tshwm sim

1. Tus naj npawb thiab txoj haujlwm ntawm cov qia

Ntab pob pob valve: Feem ntau, tsuas yog cov qia yog pom kom meej meej. Lub qia qaum yog thinner thiab tsis txuas ncaj qha rau lub pob, qee zaum txawm tias ib feem mepently los ntawm lub kaus mom.

Lub pob ntim pob hluav taws xob: ob qho tib si sab saud thiab qis dua cov kav hlau yog cov tuab thiab muaj koob meej, txuas ntxiv mus rau lub pob. Ob qho tib si stems yog pom meej los ntawm sab nraud.

2. Ua tib zoo root

Floating pob pob valve: tus qauv txheej txheem tag nrho yog qhov yooj yim, cov tsos yog qhov sib xyaw, thiab qhov loj me feem ntau me me. Vim tias lub pob floats, tsis muaj cov qauv txhim kho qauv yog qhov yuav tsum tau ua, yog li lub cev valve lub cev yog qhov nyias.

Pob zeb ruaj ruaj: vim tias lub pob yuav tsum tau tsau los ntawm sab sauv thiab qis dua cov qauv sib txawv thiab cov tsos uas muaj tag nrho yog tuab dua. Lub cev valve feem ntau yog tuab dua li ntawm lub pob ntab hauv ib lub pob hluav taws xob ntab kom haum rau cov qauv ntawm pob.

Daim Ntawv Thov Kev Pab Cuam

Floating pob valve: feem ntau siv nyob rau hauv nruab nrab- thiab qis-ntawm cov ntawv tshaj tawm thiab siv hluav taws xob ruaj khov, xws li cov tshuab dej khov thiab tso dej thiab cua txias.

Fixed Ball Valve: More suitable for high-pressure, large-diameter piping systems, as well as applications with high sealing performance and flow control requirements, such as critical piping systems in the petrochemical, natural gas transmission, and power industries.
