Flanged / Wafer Hom Triple Eccentric Npauj Npaim Valve rau qaub thiab alkaline nruab nrab
Khoom Paub meej
Triple eccentric npauj npaim valve, lub valve qia ncej qhov chaw deviates los ntawm qhov chaw ntawm lub phaj thiab lub cev qhov chaw, thiab lub rooj sib hloov axis muaj lub kaum sab xis ntawm lub axis ntawm lub cev channel.Thaum lub valve qhib tag nrho, lub phaj sealing nto yuav txawv txav ntawm lub rooj zaum sealing nto.Thaum lub phaj qhib los ntawm 0 mus rau 90 degrees, lub phaj sealing nto maj mam tawm ntawm lub rooj sealing nto, thiab lub valve qhib.Thaum lub phaj qhib los ntawm 90 mus rau 0 degrees, lub phaj sealing nto maj mam mus rau lub rooj sealing nto, thiab ces nias thiab lub valve kaw.
Qhov no tsis tsuas yog tshem tawm qhov txo qis thiab ploj ntawm qhov kev sib khi tshwj xeeb ntawm ob lub rooj sib khi nto hauv qhov qub eccentric npauj npaim valve vim lub rooj zaum elastic khoom, txias txaus, elastic tsis ua hauj lwm thiab lwm yam, ntxiv rau, lub sealing tshwj xeeb siab tuaj yeem hloov kho. arbitrarily los ntawm kev hloov lub sab nraud tsav lub sij hawm ntawm quab yuam, yog li txhim kho lub sealing kev ua tau zoo ntawm peb-eccentric npauj npaim valve, thiab zoo heev txhim kho lub neej kev pab cuam ntawm lub valve.
Valve Structure
Raws li pom nyob rau hauv daim duab hauv qab no, lub npauj npaim valve feem ntau yog tsim los ntawm lub cev valve, phaj, qia, lub nplhaib sealing, sealing packing thiab gearbox, thiab lwm yam. Peb eccentric npauj npaim valve yog nyob rau hauv lub hauv paus ntawm ob chav eccentric npauj npaim valve, tsim β Lub kaum ntse ntse. nruab nrab ntawm lub axis rotational ntawm lub rooj zaum thiab lub channel axis ntawm lub cev, eccentric lub kaum sab xis "a" ntawm lub phaj teb axis thiab lub rooj sealing axis, thiab eccentric lub kaum sab xis "b" ntawm lub phaj teb axis thiab lub axis ntawm lub cev channel rau tsim peb eccentric qauv.
Cov yam ntxwv ua haujlwm
1.Raws li qhov yuav tsum tau muaj, lub nplhaib sealing muaj ntau theem thiab tag nrho cov hlau xaiv;
2. Hlau zaum, muaj kev nyab xeeb thiab ntxuav tawm tsis kam, lub neej ntev;
3.Sealing self-compensation, zoo sealing kev ua tau zoo tsis jam ntawm qis thiab siab kub;
4.Triple eccentric qauv, muaj kev sib txhuam me ntsis ntawm lub rooj zaum thiab disc, yooj yim rau qhib thiab kaw, sealing muaj nuj nqi nrog kaw nruj dua;
5.High kub, tsis tshua muaj kub, corrosion kuj;
6. Kab rov tav mounting phau ntawv valve muaj bi-directional zaub muaj nuj nqi, qhib lub xeev ntawm lub valve tuaj yeem pom synchronously los ntawm kev khiav hauj lwm nto thiab sab.
Siv tau nruab nrab
Siv dav hauv kev siv dej thiab dej, metallurgy, roj av, tshuaj lom neeg kev lag luam, hluav taws xob hluav taws xob, kev tsim kho hauv nroog thiab lwm yam kev lag luam pipelines los txiav tawm, txuas thiab tswj kev siv nruab nrab.
