PQ sab mounted ob txoj kev kaw eccentric hemisphere valve

Lus piav qhia luv luv:

PQ sab mounted bi-directional eccentric hemisphere valve yog tsim los ntawm absorbing thiab zom cov khub clip hom loj ntws los ntawm valve (maxiflu stell ventile) ua los ntawm kwj dej tuam txhab ntawm lub teb chaws Yelemees. Nws cov qauv siv lub hauv paus ntsiab lus eccentric clamping kom ua tiav lub hom phiaj ntawm kev xauv, kho thiab kaw los ntawm kev sib kis mechanism. Lub sealing khub yog lub ntsej muag hlau lub ntsej muag nrog lub ntsej muag lub ntsej muag nyuaj, thiab lub valve tseem ceeb ntawm ob chav eccentric qauv yog nyob rau hauv qhov chaw nkaum thaum nws qhib rau hauv lub pob chamber, qhov ntws yog loj, thiab lub valve tsis scoured. . Thaum lub valve raug kaw, lub valve tseem tsis tau scoured. Thaum lub valve qhib, lub ntsej muag kheej kheej ntawm lub valve tseem ceeb asymptotically txav raws lub rooj zaum ntawm lub valve, uas tshem tawm cov teeb meem cuam tshuam thiab paub txog kev sib khi zoo. Thawj qhov tshwj xeeb yog tias nws muaj txiaj ntsig tshwj xeeb rau kev thauj mus los sib xyaw ntawm ob-theem sib xyaw ua ke yooj yim los ntsuas cov dej nag; Qhov thib ob feature yog hais tias lub hemisphere ntawm lub valve yog ua los ntawm bimetallic, lub hauv paus hlau yog overlaid nrog sib txawv alloys, lub rooj zaum valve tseem overlaid nrog sib xws surfacing, thiab sealing nto yog sib sau ua ke nrog ntau hom kev tiv thaiv corrosion, hnav- resistant, siab zog, thiab lwm yam, kom tau raws li qhov xav tau ntawm ntau zaus; Qhov thib peb feature yog nruj sealing, conveying teeb meem roj tuaj yeem ncav cuag xoom to; Qhov thib plaub feature yog hais tias lub valve tub ntxhais ntawm lub sealing khub muaj nyiaj them, thaum lub rooj zaum valve yog hnav (qhov hardness ntawm lub rooj zaum valve yog qis dua li ntawm lub valve tub ntxhais), thaum nws raug kaw, nws tseem tuaj yeem ruaj khov thiab kaw. kev pab cuam lub neej txuas ntxiv. Tsis tas li ntawd, lub rooj zaum valve tseem tuaj yeem siv tau tom qab hloov kho lossis hloov los ntawm kev tshem tawm cov txiv ntoo compression, uas tsis txhob muaj qhov tsis xws luag uas lub sealing ntawm ntau lub valve tsis siv tau thiab tag nrho lub valve raug muab pov tseg. Yog li ntawd, kev xaiv ntawm cov hlau sib txawv (los yog cov pob sib xyaw ua ke) bimetallic sealing khub tuaj yeem siv rau hauv kev lag luam sib txawv, xws li hnav tsis kam, corrosion kuj, kub tsis kam thiab nruj sealing.

Kev siv PQsab mounted ob txoj kev kaw eccentric hemisphere valve

Nws yog tsim rau kev kho dej phwj tuaj, pulp, alumina, cua sov hauv nroog, petrochemical, roj, slurry, thee tshauv, thiab lwm yam.

Khoom nta

1. Loj ncig cheeb tsam thiab me me ntws tsis kam. Qhov no yog vim hais tias tom qab qhib, lub valve core nyob rau hauv lub pob chamber, thiab cov kua yog ncaj qha mus.

2. Me me ua haujlwm torque, tig 90 degrees qhib thiab kaw, yooj yim rau kev khiav lag luam.

3. Tight seal; ob chav eccentric hlau nyuaj foob. Cov qauv tsis cuam tshuam rau qhov qhib thiab kaw, uas yog qhov tseem ceeb tshaj plaws ntawm hemisphere valve.

4. Lub neej ua haujlwm ntev, hnav-tiv taus sealing khub, nrog kev them nyiaj, lub rooj zaum valve tuaj yeem hloov kho lossis hloov.
