1 、 Center npauj npaim valve
Cov yam ntxwv ntawm tus npauj npaim valve yog qhov qia axis, npauj npaim phaj chaw thiab lub cev nruab nrab ntawm tib txoj haujlwm. Cov qauv yog yooj yim thiab kev tsim khoom yog yooj yim. Hom roj hmab lined npauj npaim valve belongs rau hom no. Qhov tsis zoo yog tias lub phaj npauj npaim thiab lub rooj zaum valve yeej ib txwm nyob rau hauv lub xeev ntawm extrusion thiab scraping, nrog loj kuj nyob deb thiab ceev ceev. Yuav kom kov yeej extrusion, scraping thiab xyuas kom meej sealing kev ua tau zoo, lub rooj zaum valve yog tsim los ntawm cov ntaub ntawv elastic xws li roj hmab lossis polytetrafluoroethylene, tab sis nws kuj raug txwv los ntawm kev siv kub. Qhov no yog vim li cas ib txwm neeg xav tias npauj npaim valve tsis tiv taus kub.
2 、 Ib leeg eccentric npauj npaim valve
Yuav kom daws tau qhov teeb meem extrusion ntawm tus npauj npaim phaj thiab lub rooj zaum ntawm cov npauj npaim concentric valve, ib qho eccentric npauj npaim valve yog tsim. Nws cov yam ntxwv tshwj xeeb yog tias lub axis ntawm lub valve qia deviates los ntawm qhov nruab nrab ntawm tus npauj npaim phaj, kom lub sab sauv thiab qis kawg ntawm tus npauj npaim phaj tsis dhau los ua kev sib hloov axis, uas disperses thiab txo cov extrusion ntau dhau ntawm sab sauv thiab qis kawg ntawm tus npauj npaim phaj thiab lub rooj zaum valve. Txawm li cas los xij, vim yog cov qauv eccentric nkaus xwb nyob rau hauv tag nrho cov txheej txheem ntawm lub valve qhib thiab kaw, qhov tshwm sim scraping ntawm npauj npaim phaj thiab lub rooj zaum valve tsis ploj, thiab nws daim ntawv thov tau zoo ib yam li concentric npauj npaim valve, yog li nws tsis tshua siv.
3 、 Ob chav eccentric npauj npaim valve
Raws li lub hauv paus ntawm ib qho eccentric npauj npaim valve, ob chav eccentric npauj npaim valve uas tau siv dav rau tam sim no tau txhim kho ntxiv. Cov yam ntxwv tshwj xeeb yog qhov axis ntawm lub valve qia deviates los ntawm qhov chaw ntawm npauj npaim phaj thiab lub cev. Cov nyhuv ntawm ob chav eccentricity enables tus npauj npaim phaj kom tawg tawm ntawm lub rooj zaum valve tam sim ntawd tom qab lub valve qhib, zoo heev tshem tawm qhov tsis tsim nyog tshaj extrusion thiab khawb qhov tshwm sim ntawm npauj npaim phaj thiab lub rooj zaum valve, txo qhov qhib qhov deb, txo qhov hnav thiab txhim kho lub neej kev pab cuam ntawm lub rooj zaum valve. Nyob rau tib lub sijhawm, ob chav eccentric npauj npaim valve tseem tuaj yeem siv lub rooj zaum hlau, uas txhim kho daim ntawv thov ntawm npauj npaim valve hauv qhov kub thiab txias. Tab sis vim nws txoj cai sealing yog txoj haujlwm sealing qauv, uas yog, lub sealing nto ntawm npauj npaim phaj thiab lub rooj zaum valve yog nyob rau hauv kab kev sib cuag, thiab elastic deformation tshwm sim los ntawm squeezing lub valve lub rooj los ntawm npauj npaim phaj tsim sealing nyhuv, yog li nws muaj siab yuav tsum tau nyob rau hauv lub kaw txoj hauj lwm (tshwj xeeb tshaj yog cov hlau valve lub rooj) thiab tsis tshua muaj siab bearing peev xwm. Qhov no yog vim li cas ib txwm muaj tib neeg xav tias npauj npaim valve tsis tiv taus qhov siab siab thiab muaj qhov xau loj.
4 、 Triple eccentric npauj npaim valve
Txhawm rau kom muaj qhov kub thiab txias, yuav tsum tau siv lub foob tawv, tab sis qhov xau yog loj; Yuav kom xoom xau, yuav tsum siv cov foob mos, tab sis tsis tiv taus kub. Txhawm rau kov yeej qhov tsis sib xws ntawm ob lub eccentric npauj npaim valve, npauj npaim valve yog eccentric rau peb lub sijhawm. Nws cov yam ntxwv nta yog hais tias lub conical axis ntawm sealing nto ntawm tus npauj npaim phaj yog inclined rau lub tog raj kheej axis ntawm lub ntsiab lub cev thaum lub axis txoj hauj lwm ntawm ob eccentric valve qia yog eccentric, uas yog hais tias, tom qab lub thib peb eccentric, lub sealing seem ntawm npauj npaim phaj yog tsis muaj tseeb lub voj voog, tab sis ib sab ntawm lub sealing. inclined mus rau hauv nruab nrab kab ntawm lub ntsiab lub cev, thiab lwm sab yog parallel mus rau hauv nruab nrab kab ntawm lub ntsiab lub cev.
