Pneumatic Npauj Npaim Valve, Tsis Siv Neeg Tswj Valve

Cov yam ntxwv ntawm cov khoom

Qhov zoo ntawm pneumatic mos sealing npauj npaim valve:

1. Cov qauv yog qhov yooj yim, qhov ntws tsis kam coefficient me me, cov yam ntxwv ntws zoo yuav ncaj, thiab tsis muaj cov khib nyiab yuav khaws cia.
2. Kev sib txuas ntawm lub phaj npauj npaim thiab lub qia valve txais tus qauv tsis muaj tus pin, uas kov yeej qhov tshwm sim hauv qhov to.
3. Muab faib ua pneumatic wafer hom mos sealing npauj npaim valve thiab pneumatic flange mos sealing npauj npaim valve kom tau raws li cov kav dej sib txawv.
4. Cov ntsaws ruaj ruaj tuaj yeem hloov tau, thiab kev ua haujlwm sealing yog txhim khu kev qha thiab tuaj yeem ua tiav xoom xaim ntawm bidirectional sealing.
5. Cov khoom siv sealing yog resistant rau kev laus, corrosion thiab kev pab lub neej ntev.

Pneumatic mos sealing npauj npaim valve parameter piav qhia:

1.Nominal txoj kab uas hla: DN50 ~ DN1200 (mm).
2.Pressure chav kawm: PN1.0, 1.6, 2.5MPa.
3.Txoj kev sib txuas: Wafer lossis flange txuas.
4.Spool daim ntawv: disc hom.
5.Drive hom: Cua qhov chaw tsav, compressed cua 5 ~ 7bar (nrog tes log).
6. Kev ua haujlwm ntau: 0 ~ 90 °.
7.Sealing khoom: txhua yam roj hmab, PTFE.
8.Lub sijhawm ua haujlwm: Ntau yam corrosive media, thiab lwm yam (qhov kub thiab txias, lub sijhawm tsis tshua muaj siab thiab tsis tshua muaj siab).
9.Accessory xaiv: positioner, solenoid valve, cua lim siab reducer, retainer valve, mus txawv tebchaws hloov, valve txoj hauj lwm transmitter, handwheel mechanism, thiab lwm yam.
10.Control hom: hloov ob txoj hauj lwm tswj, cua-qhib, cua-kaw, caij nplooj ntoos hlav rov qab, ntse hloov hom (4-20mA analog teeb liab).

Pneumatic nyuaj sealing npauj npaim valve kev ua haujlwm yam ntxwv:

1. Kev siv lub hauv paus ntsiab lus triple eccentric, lub rooj zaum valve thiab lub phaj phaj yuav luag tsis muaj kev sib txhuam thaum qhib thiab kaw, uas txhim kho lub neej kev pab cuam.
2. Cov qauv tshwj xeeb, kev ua haujlwm yooj yim, kev txuag hluav taws xob, yooj yim, tsis cuam tshuam los ntawm kev kub siab lossis qis nruab nrab, thiab txhim khu kev qha sealing kev ua tau zoo.
3. Nws tuaj yeem muab faib ua pneumatic wafer hom hard sealing npauj npaim valve thiab pneumatic flange nyuaj sealing npauj npaim valve, uas yog tsim rau ntau txoj kev sib txuas thiab yooj yim rau nruab rau hauv cov kav dej.
3. Lub sealing yog tsim los ntawm laminated mos thiab tawv hlau los xij, uas muaj ob qhov zoo ntawm cov hlau sealing thiab elastic sealing, thiab muaj cov yam ntxwv zoo sealing ntawm qhov kub thiab txias.
5. Lub npauj npaim valve yog nruab nrog lub sealing hloov kho.Yog tias qhov kev sib khi ua haujlwm tau qis dua tom qab siv mus ntev, qhov kev sib khi thawj zaug tuaj yeem rov qab los ntawm kev kho lub nplhaib sealing kom ze rau lub rooj zaum valve, uas ua rau lub neej ua haujlwm zoo.
