Cov hlau hluav taws xob rau hlau npauj npaim li qub yog siv dav hauv metallurgy, hluav taws xob, petrochemical, dej thiab dej ntws, kev tsim kho hauv nroog thiab lwm yam kev lag luam uas qhov kub nruab nrab yog ≤425 ° C los kho qhov ntws thiab txiav cov kua dej.Thaum lub sij hawm lub teb chaws hnub so lub sij hawm, lub NSEN rhiav ua kom tiav ib tug batch ntawm on-off hluav taws xob bi-directional sealing hlau npauj npaim li qub. Qhov no batch ntawm hluav taws xob npauj npaim li qub yuav paub txog tej thaj chaw deb tswj thiab lcoal lag luam.

● Lub bracket txuas siv tus qauv ISO5211 thiab tuaj yeem txuas nrog ntau yam hluav taws xob, pneumatic, hydraulic, phau ntawv thiab lwm yam khoom siv tsav tsheb

●Muaj qee qhov deb ntawm sab saum toj ntawm lub flange sab saum toj thiab lub actuator ua haujlwm, uas pab tiv thaiv lub actuator los ntawm cua sov dhau

ON OFF hom hluav taws xob npauj npaim valve wiring terminals daim duab

Thaum lub tshuab hluav taws xob xa tuaj, qhov stroke ntawm lub tshuab tswj tau raug kho. Txhawm rau kom tiv thaiv lub zog los ntawm kev txuas mus rau qhov tsis raug, tus neeg siv yuav tsum qhib lub phaj valve 30 degrees ua ntej tig lub zog rau thawj zaug, thiab xyuas qhov kev taw qhia ntawm lub phaj qhia thiab qhov kev taw qhia qhib ntawm lub valve. Puas yog nws sib xws? Tom qab ntawd rov qab kho phau ntawv qhia rau hluav taws xob, ua raws li cov lus qhia, daim duab qhia txog kev sib txuas, daim duab qhia txog kev tswj hwm, thiab paub meej tias qhov kev sib txuas yog, thiab tom qab ntawd qhib / kaw lub valve los ntawm lub pob ntawm lub thawv tswj. Yog tias lub xov hluav taws xob txuas rov qab, nws yuav ua rau lub pob hloov mus ncig ua tsis tiav thiab ua puas rau cov iav kab thiab cov khoom siv hluav taws xob.

Thaum lub qhov hluav taws xob npauj npaim valve siv, yog tias nws tsis ua haujlwm, tsum tsis txhob siv nws tam sim ntawd thiab nrhiav qhov ua rau

Cov yam ntxwv ntawm lub zog fais fab foob npauj npaim valve:

Tus qauv tsim ntawm lub hauv paus ntsiab lus triple eccentricity ua rau qhov chaw txav mus los ntawm qhov chaw sealing zoo tagnrho. Tsis muaj kev sib txhuam thiab kev cuam tshuam ntawm cov nplaim sealing. Tsis tas li ntawd, cov khoom siv sealing raug xaiv kom raug, yog li ntawd lub npauj npaim valve muaj kev ua haujlwm sealing, tiv taus corrosion, tiv taus kub siab thiab tiv taus. Qhov grindability tau lees paub zoo. Nws cov yam ntxwv tseem ceeb yog raws li nram no:

1. Me me ua haujlwm torque, yooj yim ua haujlwm, txuag zog thiab ntse;

2. Cov qauv eccentric peb-seem ua rau lub npauj npaim disc nruj dua thiab nruj dua, thiab nws cov kev ua haujlwm sealing yog qhov ntseeg tau, ua tiav xoom xau;

3. Kev ua haujlwm siab, kev tiv thaiv corrosion, hnav tsis kam, lub neej ntev, thiab lwm yam.
