Pneumatic pob valve yog ib qho kev siv hluav taws xob uas tswj kev sib hloov ntawm cov kua rau / tawm lossis ntws los ntawm kev siv cua. Nws cov yam ntxwv tseem ceeb thiab cov ntawv thov muaj raws li hauv qab no:
1. Cov qauv qauv thiab cov ntsiab cai ua haujlwm
Yooj yim sib xyaw
Ball valve body : includes a ball with a through hole (stainless steel/alloy material), a valve seat (PTFE/metal seal), a valve body (cast or welded) and a valve stem.
Pneumatic Actuator: hloov pauv pa taws mus rau hauv kev kho tshuab tig mus rau tig lub pob kom hloov lub pob kom tig 90℃(tus qauv sib koom ua ke (v-hom kev tswj hwm valve).
Kev ua hauj lwm
Qhib: compressed cua thawb cov actuator piston → tsav lub pob valve kom tig mus rau lub qhov yog mus raws li cov raj xa dej kom ua tiav.
Kaw: Cov huab cua tau txiav tawm → lub caij nplooj ntoos hlav rov qab lub piston → Cov pob roughates 90℃→ lub qhov cub cov kua dej.
Cov kev cai: Cov huab cua siab yog tswj hwm los ntawm txoj haujlwm kom raug kho lub pob qhib (xws li v-hom pob valve kom ua tiav linar Flow tswj).
2. Hom Ke thiab Nta
Kev faib tawm los ntawm cov qauv
Floating pob valve: lub nruab nrab siab thawb lub pob mus nias lub rooj valve, nrog ib tus qauv yooj yim, haum rau hauv nruab nrab thiab muaj sib npaug rau 4.0MPA). Pob zeb ruaj ruaj ruaj ruaj: lub pob yog tsau los ntawm cov kabmob, lub rooj tog hluav taws xob txav mus los thiab muaj ntau dua los yog sib npaug (xws li cov roj kom tswj tau). Elastic pob valve: lub pob muaj ib qho grastic groove thiab tseem kaw nyob rau hauv qhov kub thiab kev kub siab ntau yam khoom lag luam oomonia ntau lawm). Kev faib tawm los ntawm kev ua haujlwm
O-hom pob valve: Cov Khoom Siv Puv-right-righ kuj V-hom pob valve: cov txiav-tawm pob tuaj yeem txiav fibers / hais thiab raug kho cov ntws (xws li ntawv sis ntawv sis cov ntawv sis cov ntawv. Ntau txoj kev pob valve: T-hom / L-Ntaus Fl Flor Raws li kev ua kom muaj kev sib txawv, xws li cov kev coj ua tshuaj ntsuab (xws li tshuaj tsuag tshuaj ntsuab (xws li tshuaj reactor pub mis).
3. Cov ntsiab lus zoo thiab cov chaw thov
Zoo kawg nkaus zoo heev
Cov lus teb ceev: 0.5 ~ 2 vib nas this los ua kom tiav qhov hloov pauv hloov, deb tshaj phau tuav lub valve.
Intrinsically muaj kev nyab xeeb: tsis muaj hluav taws xob tej hluav taws xob, haum rau cov nplaim taws thiab cov khoom tawg (xws li petrochemicals, hydrogen zog).
Kev tswj hwm cov chaw taws teeb: Koom tes nrog solenoid li qub / plc kom ua tiav kev siv tshuab thiab txo cov kev cuam tshuam ntawm kev tiv thaiv phau ntawv.
Raug Daim Ntawv Teev Lus
Kev Lag Luam Zog: Roj Pipeline Qhib thiab kaw (Tsau pob Valve), Fais Fab Cog Chav Ua Haujlwm.
Tshuaj thiab cov khoom siv: corrosive nruab nrab txiav (ptfe foob), reactor rawor cov khoom siv sib piv.
Kev tiv thaiv ib puag ncig teb: Dej kev kho mob (particle hnav tiv taus v-hom pob valve).
Khoom noj khoom haus Engineering: xws li kua tswj kua dej (huv si cov pob poluished polished poll valve).
4. Xaiv thiab txij nkawm cov ntsiab lus
Cov kev tsis sib haum xeeb rau kev xaiv
Cov yam ntxwv nruab nrab: Cov kua ntshav txhaws yuav tsum xaiv cov hlau stainless + PTFE ntsaws, thiab v-hom pob li qub yog siv rau particle-muaj tshaj tawm. Siab thiab kub: rau ultra-siab siab (> 32Mpa), tsau pob hlau cov ntsaws ruaj ruaj siv; Rau qhov kub siab (> 200 degree), cov alloys tshwj xeeb yuav tsum muaj.
Actuator: loj-caliber / kev kub siab li qub yog nruab nrog piston actuatators (loj thawb); Pneumatic actuatators xaiv es tsis yog hluav taws xob ua yeeb yam hauv kev tawg-ntawv pov thawj.
Saib Xyuas
Nquag hloov Valve lub rooj raj (muag muag lub neej yog 1 ~ 2 xyoos);
Txheeb xyuas cov pa roj triplex (lim, siab txo qhov valve, roj cias yuam kev) kom ntseeg tau cua ruaj khov huab cua siab.
Piv txwv li: Kev siv tshuaj lom neeg siv tshuaj pneumatic tsau lub cev (stainless hlau ntsaws lub cev) los tswj hwm 10 teev standorine hluav taws xob, thiab cov chaw taws teeb txiav tawm kom tau tiav los ntawm PLC.
