Ductile hlau npauj npaim valve lug hom yog siv los tswj dej thiab lwm yam xov xwm tshaj tawm cov ntaub ntawv ntawm kev tsim kho. Lug style npauj npaim li qub yog sandwich mounted ntawm cov neeg siv khoom ANSI / ASME Class 150 thiab lwm yam thoob ntiaj teb flanges. Txheem ISO5211 sab saum toj mount tso cai rau kev yooj yim installation ntawm pneumatic actuators, hluav taws xob actuators lossis phau ntawv tuav.
Lug lub cev npauj npaim li qub yog siv nyob rau hauv cov xwm txheej uas lub valve yuav tsum nyob twj ywm nyob rau hauv qhov chaw thaum ib daim ntawm cov yeeb nkab raug tshem tawm. Rau lub qhov rooj los yog sab nrauv mounting, lub cev yog xav tau los ntawm kev ntsuas. Lub Hom Phiaj Npauj Npaim Valve 313207 muaj lub cev lub cev hauv cov hlau nplaum. Kev ntsuas siab yog 200 psi. Lub valve ua raws li MSS-SP-67 specification. Npauj npaim li qub yog ua haujlwm rau 2" - 8" thiab iav ua haujlwm rau 10" thiab siab dua.
Khoom Paub meej
Npauj npaim li qub yog lub quarter-tig li qub siv los cais lossis tswj kev ntws. Nws muaj lub disc uas tso cai los yog tiv thaiv kom tsis txhob muaj cov kua dej. Kev ua haujlwm ntawm npauj npaim valve zoo ib yam li lub pob valve, thiab tus kov tuaj yeem tig 90 degrees kom qhib lossis kaw lub valve. Npauj npaim li qub tau dav ntsia rau ntawm cov kav dej vim lawv cov nqi qis dua thiab sib dua.
Nta
- Ib qho tshwj xeeb triple seal system yog siv rau kev sib khi, tshem tawm cov pa phem lossis cov xau thib ob.
- Tus kheej-lubricating PTFE-lined bearings yog siv nyob rau hauv ob qho tib si tsav thiab tsis-tsav kawg shafts kom ntseeg tau tias tsawg kawg nkaus kev sib txhuam torque ntawm cov bearings.
- Lub rooj zaum gasket txuas mus rau qhov chaw sib cuag flange, tshem tawm qhov xav tau ntawm lub flange gasket cais thaum lub sijhawm teeb tsa.
- Tswj lub compression ntawm gasket nto los muab kev pom zoo foob thiab tiv thaiv gasket nto shattering tsis ua hauj lwm.
- Ob-txoj kev valve muaj qhov kaw kaw ntom nti kaw, uas tuaj yeem ua kom lub tshuab nqus tsev ntawm qhov ntsuas ntsuas hauv ob qho kev taw qhia.
- Kev yoog tau zoo heev rau kev ua haujlwm los ntawm cov txheej txheem sab saum toj flange mounting qhov ntev rau actuator mounting.
- Haum rau kev qhib / tawm thiab ua haujlwm throttling.
- Xaiv lub rooj zaum thiab cov ntaub ntawv disc kom haum rau cov xwm txheej xov xwm thiab cov kev pabcuam.
- Lug-rau-clip kev tsim kho kom paub meej tus kheej ntawm lub valve ntawm mating flanges.
- Kev ntsuas lub rooj zaum qis tuaj yeem siv los txo qis kev ua haujlwm torque thiab txuas ntxiv lub neej ntawm lub rooj zaum ntawm kev ua haujlwm qis.
Cov ntaub ntawv khoom
1. Specifications:
Npauj npaim valve yog lub quarter-tig valve siv rau qhib thiab kaw thiab tswj kev khiav hauv cov kav dej. Nws muaj ib tug disc mounted rau ib tug ncej. Los ntawm tig lub kov ib lub quarter tig, lub disc yuav tig mus rau qhov qhib lossis kaw. Thaum lub valve tig mus rau qhov chaw qhib, lub disc txav deb ntawm lub rooj zaum thiab sib npaug mus rau cov kev taw qhia ntawm ntws. Nyob rau hauv txoj hauj lwm kaw, lub disc yog perpendicular mus rau cov kev taw qhia ntawm ntws thiab yog kaw los ntawm lub rooj zaum. Ib nrab kev sib hloov ntawm tus kov yog tsim rau daim ntawv thov throttle. Tsim thiab tsim raws li API 609 tus qauv. Kev tshuaj xyuas thiab kev sim yog ua raws li API 598 tus qauv. Npauj npaim li qub tau dav ntsia rau hauv cov khoom siv ua kua xws li petrochemical, dej, kev tiv thaiv hluav taws, thiab kev kho dej tsis zoo.
2. Khoom siv thiab tsim:
Npauj npaim li qub yog ua los ntawm cam khwb cia hlau thiab yog tus nqi qis nrog cov qauv kev ua tau zoo. Sab nrauv ntawm lub valve lub cev yog pleev xim rau xim xiav rau kev txhim kho corrosion kuj. Lub rooj zaum yog ua los ntawm cov khoom siv EPDM thiab haum rau ntawm ntug ntawm lub disc kom kaw cov dej xau.
Npauj npaim li qub yog tsim nrog lugs. Lub lug style npauj npaim valve zoo ib yam li tsim rau lub wafer style npauj npaim valve, nrog lub cev ntev, tab sis nrog threaded bolt qhov nyob rau sab nraum lub cev. Tus naj npawb ntawm cov xov bolt qhov yog nyob ntawm qhov loj ntawm lub valve, 4 qhov kev xaiv muaj rau qhov ntau thiab tsawg hauv qab 4 "thiab 8 qhov kev xaiv muaj rau qhov ntau thiab tsawg dua 4".
3. Hom kev sib txuas:
Rau cov hlau npauj npaim valve lug hom, muaj threaded bolt qhov nyob rau sab nraum lub valve lub cev. Ntau cov bolts txuas ob lub flanges mus rau lub qhov rooj threaded ntawm ob sab nrog fastening bolts, thiab npauj npaim valve yog nyob rau hauv nruab nrab.
Txhawm rau daws qhov teeb meem clogging, lub npauj npaim valve no tau sib sau ua ke rau hauv av, siv ob sab screws (tsis muaj txiv ntseej) rau kev teeb tsa. Nws tuaj yeem ua kom haum txhua hom kua dej thiab kev txwv, thiab zoo li WAFER, LUG npauj npaim valve muaj ob lub ntsiab lus ntawm kev sib txhuam. Lub rooj vag valve no yog siv los tshem tawm ib sab ntawm chav tsev thaum ua kom lwm sab nyob rau hauv siab thiab ua haujlwm puv.
