(1) Cov qauv ntawm lub ntiaj teb valve yog yooj yim dua li lub rooj vag valve, thiab kev tsim khoom thiab kev saib xyuas yooj yim dua.
(2) sealing nto tsis yooj yim rau hnav thiab khawb, zoo sealing, qhib thiab kaw ntawm lub valve disc thiab lub valve lub cev sealing nto yam tsis muaj tus txheeb ze zawv zawg, yog li hnav thiab khawb tsis hnyav, sealing kev ua tau zoo, kev pab lub neej ntev.
(3) thaum qhib thiab kaw, disc stroke me me, yog li qhov siab ntawm lub ntiaj teb valve yog me dua li lub rooj vag valve, tab sis qhov ntev ntawm cov qauv yog ntev dua li lub rooj vag valve.
(4) qhib thiab kaw torque loj, qhib thiab kaw stranding yog laborious, qhib thiab kaw lub sij hawm yog tus tseem ceeb.
(5) Cov dej tsis kam yog qhov loj, vim tias qhov nruab nrab ntawm lub valve lub cev yog tortuous, cov dej tsis kam yog loj thiab lub zog noj loj.
(6) thaum lub nominal siab Pn nyob rau hauv cov kev taw qhia ntawm nruab nrab ndlwg yog tsawg dua los yog sib npaug zos rau 16Mpa, nws yog feem ntau downstream, thiab qhov nruab nrab ntws los ntawm lub qis kev taw qhia ntawm lub valve disc;Nominal siab Pn ≥ 20Mpa, feem ntau siv countercurrent, nruab nrab ntws los ntawm cov kev taw qhia ntawm lub disc.Txhawm rau kom muaj peev xwm sealing.Thaum siv, qhov nruab nrab ntawm qhov txiav tawm tsuas tuaj yeem ntws mus rau hauv ib qho kev taw qhia thiab tsis tuaj yeem hloov cov kev taw qhia ntws.
(7) Thaum qhib tag nrho, lub disc feem ntau eroded.
Lub axis ntawm lub valve qia ntawm lub ntiaj teb valve yog perpendicular rau lub sealing nto ntawm lub rooj zaum valve.qia qhib / kaw stroke yog luv luv thiab muaj kev txhim khu kev qha txiav-tawm, ua rau lub valve no haum rau nruab nrab txiav tawm lossis tswj thiab siv throttling.

Nortech yog ib qho ntawm cov ua lag luam valve manufacturers hauv Suav teb nrog cov ntawv pov thawj zoo ISO9001.
