Ixabiso lefektri i-DN50-DN2000 i-Worm gear i-butterfly valve enerabha eneempahla ezithengiswayo
Yintoni ivalvu yebhabhathane efakwe irabha?
Ivalvu yebhabhathane enomphetho ngerabha ikwabizwa ngokuba yi-"concentric","rubber lined" kunye ne-"rubber seated" butterfly valve, inesihlalo serabha (okanye esiqinileyo) phakathi kobubanzi bangaphandle bediski kunye nodonga lwangaphakathi lwevalufa.Ivalvu yebhabhathane ikwasetyenziswa njengevalvu elawula ukuhamba kwamanzi, ukuba idiski ayijikelezi ukuya kumjikelo wekota epheleleyo, oko kuthetha ukuba ivalvu ivulekile kancinci, singalawula ukuhamba kwamanzi nge-open angle eyahlukeneyo.
Ivalvu yebhabhathane enomphetho ngerabha,Ihlala isetyenziswa apho ivalvu ikwisiphelo sombhobho kuba akukho flange yesibini yokubopha izikhonkwane. Endaweni yoko, iilugs ziphoswa kwivalvu enemingxuma eqhotyoshiweyo ehambelana nepateni yebolt yobukhulu kunye nohlu loxinzelelo lweflange. Iibolts zidlula kwimingxuma yeflange kwaye zifakwa kwimingxuma eqhotyoshiweyo yelug.
Ivalvu yebhabhathane enomphetho ngerabha,Uyilo oluncinci kakhulu olunemifutshane yobuso nobuso. Ingena phakathi kweeflange ezimbini, kunye neestud ezidlula ukusuka kwenye iflange ukuya kwenye. Ivalvu ibanjwe endaweni yayo kwaye ivalwe nge-gasket ngenxa yoxinzelelo lweestud. Uhlobo lwe-valve yebhabhathane ehleli phantsi ehlala iqinile sisisombululo esikhaphukhaphu, esingenakulungiswa, esingabizi kakhulu, nesithembekileyo kwizicelo ezahlukeneyo.
Iimpawu eziphambili ze-NORTECH resilient seated butterfly valve lug type
Iimpawu eziphambili yeIvalvu yebhabhathane enomphetho ngerabha
- I-flange ephezulu ye-ISO 5211 ilungele ukwenza kube lula ukwenza izinto ngokuzenzekelayo kunye nokulungiswa kwakhona kwe-actuator.
- Iitorque eziphantsi zokusebenza zibangela ukuba kube lula ukusebenza kunye nokukhetha i-actuator engabizi kakhulu.
- Iibheringi ezifakwe kwi-PTFE zenzelwe ukulwa nokungqubana kunye nokuguguleka, akukho lubrication ifunekayo.
- I-lining efakwe emzimbeni, i-liner kulula ukuyitshintsha, akukho mhlwa phakathi komzimba kunye ne-lining, ifanelekile ukusetyenziswa ekupheleni komgca.
- Ukwakhiwa okuncinci kwenza kube nzima kakhulu, kubekho indawo encinci yokugcina nokufakela.
- Indawo yeshafti ephakathi, ukuqina kweqamza eliya kwicala eliphakathi, okwenza ukufakwa kwamkeleke nakweyiphi na indlela.
- Umzimba ozele yimbobo awuniki ukumelana okuncinci nokuhamba kwamanzi
- Akukho mingxunya kwindlela yokuhamba kwamanzi, nto leyo eyenza kube lula ukuyicoca nokubulala iintsholongwane kwinkqubo yamanzi okusela njl.
