Lub siab regulator yog cov cuab yeej tswj xyuas uas txo cov roj cua siab rau cov pa roj tsawg thiab ua kom lub siab thiab ntws tawm ntawm cov roj tso tawm kom ruaj khov.Nws yog ib qho khoom siv tau zoo thiab yog ib qho tsim nyog thiab feem ntau nyob rau hauv cov kav dej roj.Vim yog cov khoom lag luam teeb meem tsis zoo thiab siv tsis tu ncua Qhov ua rau hnav yuav ua rau cov pa tawm hauv lub cev valve.Hauv qab no, cov chaw tsim khoom ntawm AFK siab reducer los ntawm Wofly Technology yuav piav qhia cov laj thawj thiab cov kev daws teeb meem rau kev tso tawm sab hauv ntawm lub siab tswj.
Yog vim li cas rau internal leakage ntawm lub valve:Lub valve qhib los ntawm huab cua, lub valve qia ntev dhau lawm thiab lub valve qia luv dhau, thiab qhov nce (lossis downward) qhov deb ntawm lub valve qia tsis txaus, ua rau muaj qhov sib txawv ntawm lub valve core thiab lub rooj zaum valve, uas tsis tuaj yeem tiv tauj tag nrho, ua rau kaw Lax thiab sab hauv to.
Kev daws:
1. Lub qia ntawm lub regulating valve yuav tsum tau luv luv (los yog lengthened) kom qhov ntev ntawm lub qia yog tsim nyog thiaj li hais tias nws tsis mus rau sab hauv.
2. Yog vim li cas rau packing to:
(1) Cov ntim khoom yog nyob rau hauv kev sib cuag nrog lub valve qia tom qab tau ntim rau hauv lub thawv ntim khoom, tab sis qhov kev sib cuag no tsis zoo li qub, qee qhov yog xoob, qee qhov nruj, thiab qee qhov tsis zoo.
(2) Muaj kev sib txheeb ze ntawm lub qia valve thiab cov ntim khoom.Nrog rau kev cuam tshuam ntawm qhov kub thiab txias, kev kub siab thiab muaj zog permeability nruab nrab, lub ntim yuav xau.
(3) Packing contact pressure maj attenuates, packing nws tus kheej thiab lwm yam vim li cas, qhov nruab nrab yuav los ntawm qhov sib txawv.
Kev daws:
(a) Txhawm rau kom yooj yim rau cov ntim ntawm cov ntim, chamfer sab saum toj ntawm lub thawv stuffing, thiab tso cov phiaj loj me me nyob hauv qab ntawm lub thawv ntim khoom kom tiv thaiv cov nruab nrab.
(b) Qhov chaw tiv tauj ntawm lub thawv ntim khoom thiab cov ntim khoom yuav tsum du kom txo tau cov khoom hnav.
(c) Saj zawg zog graphite raug xaiv los ua cov muab tub lim, uas muaj cov yam ntxwv ntawm huab cua zoo, kev sib txhuam me me, deformation me me, thiab tsis muaj kev hloov pauv hauv kev sib txhuam tom qab rov nruj dua.
3. Lub valve core thiab lub rooj zaum tseem ceeb ntawm cov tswj valve yog deformed thiab leaked.Lub ntsiab yog vim li cas rau qhov to ntawm lub valve tub ntxhais thiab lub rooj zaum valve yog tias lub casting los yog casting tsis xws luag nyob rau hauv cov txheej txheem ntawm kev tswj valve tuaj yeem ua rau muaj zog corrosion.Kev nkag mus ntawm corrosive media thiab yaig ntawm cov kua nruab nrab yuav ua rau kev yaig thiab yaig ntawm lub valve core thiab cov khoom siv lub rooj zaum valve.Qhov cuam tshuam ua rau lub hauv paus valve thiab lub rooj zaum valve kom deform (lossis hnav) tawm ntawm qhov sib txuam, tawm hauv qhov khoob thiab tawm.Kev daws: Xaiv cov khoom siv corrosion-resistant rau valve core thiab valve rooj.Yog tias qhov abrasion thiab deformation tsis loj, cov ntawv xuab zeb zoo tuaj yeem siv los zom kom tshem tawm cov kab thiab txhim kho smoothness.Yog tias qhov deformation hnyav, tsuas yog hloov lub valve core thiab lub rooj zaum valve.
