Xaiv cov khoom siv kub-kub kaw ntom nti tswj li qub

Kev xaiv khoom

1. Cov khoom siv hlau

Stainless hlau: xws li 304, 316, thiab lwm yam., muaj corrosion kuj zoo thiab kub lub zog, thiab yog ib tug nquag siv valve khoom.
Nickel-raws li alloys: xws li Inconel, Hastelloy, thiab lwm yam., muaj qhov kub thiab txias tsis kam thiab corrosion kuj, thiab tsim nyog rau ntau qhov chaw xav tau.
Titanium alloy: muaj qhov kub thiab txias tsis kam thiab corrosion kuj, tab sis tus nqi kuj siab.

2. Cov khoom siv tsis yog hlau

Graphite: Raws li cov khoom sib khi, graphite muaj qhov kub thiab txias tsis kam thiab nws tus kheej lubricating zog.
Ceramics: xws li silicon carbide, silicon nitride, thiab lwm yam., muaj cov hardness siab heev thiab kub tsis kam, thiab feem ntau yog siv rau lub valve linings los yog coatings.

Kev xav txog kev tsim qauv

1. Sealing tsim

Mos foob: Siv cov ntaub ntawv hloov tau yooj yim (xws li roj hmab) ua cov ntsaws ruaj ruaj, haum rau qhov kub thiab txias.
Hard seal: Siv hlau-rau-hlau sealing, haum rau qhov kub thiab txias ib puag ncig.

2. Tus qauv tsim

Flow channel tsim: Ua kom zoo tshaj qhov ntws channel zoo kom txo tau cov dej tsis kam thiab cov cua kub sib xyaw.
Thaum tshav kub kub dissipation tsim: ntxiv cov dab dej kub los yog txais cov qauv tshwj xeeb los txhim kho cov cua sov kom zoo.

3. Kev ua haujlwm thiab kev saib xyuas

Yooj yim rau kev khiav lag luam: Cov qauv tsim yuav tsum yooj yim rau kev khiav lag luam thiab tswj, xws li teeb tsa qhov rais saib, ua kom yooj yim hauv cov qauv, thiab lwm yam.
Kev saib xyuas tsis tu ncua: tsim cov phiaj xwm kev saib xyuas, tsis tu ncua xyuas thiab hloov cov khoom hnav.

Kev xaiv cov khoom siv thiab tsim kev kub ceev kawtswj li qubyog cov txheej txheem nyuaj uas yuav tsum tau xav txog ntau yam, suav nrog ib puag ncig ua haujlwm, tus nqi, kev ntseeg siab thiab lub neej. Los ntawm kev xaiv cov khoom tsim nyog thiab ua tib zoo tsim, kev ua haujlwm thiab kev nyab xeeb ntawm lub valve nyob rau hauv huab cua txias tuaj yeem ua kom ntseeg tau.
