Hom los ntawm cov qauv qauv, yog hauv qab ob hom.
1.Centerline Npauj Npaim Valve
ib. Qhov zoo: Cov qauv yooj yim thiab yooj yim rau kev tsim khoom, kev lag luam;
b. Qhov tsis zoo: Lub phaj npauj npaim thiab lub rooj zaum valve yeej ib txwm nyob rau hauv lub xeev ntawm extrusion thiab scraping, qhov kev ncua deb yog loj thiab hnav yog ceev.
c. Daim ntaub ntawv: Siv dav hauv ntau qhov chaw xws li roj av, tshuaj lom neeg, metallurgy, thiab hydropower.
2.Eccentric Npauj Npaim Valve
ib. Qhov zoo: Sawv qhov kub thiab txias, Txhim kho lub neej ntawm lub rooj zaum valve
b. Disadvantages: kim thiab ntau nyuaj rau kev tsim khoom
c. Daim ntaub ntawv: Siv dav hauv cov kav dej ntawm cov kav dej thiab cov kav dej, dej phwj tuaj, kev tsim kho, roj av, tshuaj, lub teeb textile, ntawv ua, hydropower, metallurgy, zog, thiab lwm yam dej num.
Cia peb txheeb xyuas cov ntsiab lus tseem ceeb thiab kev txhim kho keeb kwm ntawm Centerline npauj npaim valve thiab eccentric npauj npaim valve kom ntxaws.
Lub centerline Npauj Npaim Valve yog tus cwj pwm los ntawm qhov chaw ntawm lub qia axis, qhov nruab nrab ntawm tus npauj npaim phaj, thiab qhov nruab nrab ntawm lub cev nyob rau hauv tib txoj hauj lwm, raws li ib tug raug centerline valve. Lub concentric npauj npaim valve, feem ntau yog los ntawm loj DN50 mus rau DN2200, Lub sealing ntawm nruab nrab kab npauj npaim valve yog mos, yog li nws yog qhov kub thiab txias valve. Lub nplhaib hlau npauj npaim valve yog ib qho ntawm cov npauj npaim npauj npaim li qub
Siab: DN
Kub: Raws li cov ntaub ntawv sealing, Piv txwv li, NBR, Max kub: 100 ℃, EPDM, Max kub: 150 ℃; FRM, Max kub: 200 ℃; SBR, Max kub: 100 ℃; CR, Max kub: 100 ℃; NR, Max kub: 70 ℃; HR, Max kub: 100 ℃; UR, Max kub: 40 ℃.
Rau eccentric npauj npaim valve, lawv yog peb hom
ib. Ib Eccentric Npauj Npaim Valve
b. Ob chav eccentric npauj npaim valve
Keeb kwm ntawm eccentric npauj npaim valve hom
Ib qho eccentric npauj npaim valve yog ib hom npauj npaim valve tsim los daws qhov teeb meem ntawm nyem lub npauj npaim phaj thiab lub rooj zaum hauv nruab nrab kab npauj npaim valve. Lub qia axis deviates los ntawm qhov chaw ntawm npauj npaim valve kom qhov qis kawg ntawm npauj npaim valve tsis dhau los ua lub axis ntawm kev sib hloov, uas disperses thiab txo cov kev hloov pauv ntawm lub sab sauv thiab qis kawg ntawm npauj npaim phaj thiab lub rooj zaum valve.
Ob chav offset npauj npaim valve yog ib yam ntawm cov npauj npaim valve hom, lub qia axis tawm ob qho tib si nruab nrab ntawm npauj npaim phaj thiab lub cev qhov chaw. Cov nyhuv ntawm ob chav eccentricity enables tus npauj npaim phaj kom sai sai tshem tawm ntawm lub rooj zaum tom qab lub valve qhib, uas yuav pab tshem tawm ntau dhau squeezing thiab scraping ntawm npauj npaim phaj thiab lub rooj zaum thiab txhim kho lub rooj zaum lub neej. Qhov kev txo qis ntawm kev khawb ua rau nws tuaj yeem siv cov rooj zaum hlau rau ob chav eccentric npauj npaim li qub, uas tuaj yeem siv rau hauv cov ntawv thov kub.
Triple eccentric npauj npaim valve yog hom npauj npaim valve, rau lub qia axis txoj hauj lwm sib txawv nyob rau tib lub sij hawm, ua rau lub conical axis ntawm npauj npaim phaj sealing nto deviate los ntawm lub cev cylindrical axis, sealing nto ntawm npauj npaim phaj yog elliptical, Cov duab ntawm lub sealing nto yog li asymmetric, ib sab yog inclined rau lub cev centerline, lwm sab yog parallel rau lub cev centerline.Peb eccentric npauj npaim li qub tau hloov pauv qhov chaw sib khi, tsis muaj txoj haujlwm sib khi, tab sis torsion sealing, tso siab rau qhov chaw sib cuag ntawm lub rooj zaum valve kom ua tiav cov nyhuv sealing, daws qhov teeb meem ntawm xoom xau ntawm lub rooj zaum hlau. Txij li thaum kev sib cuag saum npoo siab thiab nruab nrab siab yog proportional, nws kuj daws tau qhov teeb meem ntawm kev kub siab thiab kub siab, thiab npauj npaim valve yog siv ntau dua.
