Qhov qhib thiab kaw cov tswv cuab (pob) yog tsav los ntawm lub valve qia thiab tig ib ncig ntawm lub axis ntawm lub valve qia.Feem ntau yog siv los txiav tawm lossis txuas qhov nruab nrab hauv cov raj xa dej, kuj tseem tuaj yeem siv rau kev tswj cov dej thiab tswj, hom valve hauv cov kav dej feem ntau yuav tsum tau nruab kab rov tav.
Yas pob valve nta:
(1) Kev ua haujlwm siab: kev ua haujlwm siab ntawm ntau yam khoom ntawm qhov kub thiab txias tuaj yeem ncav cuag 1.0Mpa.
(2) Kev siv dav dav: kev siv PVDF kub yog -20 ℃ ~ + 120 ℃;Kev khiav hauj lwm kub ntawm RPP yog -20 ℃ ~ + 95 ℃;Kev ua haujlwm kub ntawm UPVC yog -50 ℃ ~ + 95 ℃.
(3) Kev cuam tshuam zoo: RPP, UPVC, PVDF, CPVC muaj zog txhua yam thiab cuam tshuam.
(4) cov kua dej tsis kam yog me me: cov khoom sab hauv phab ntsa yog du, kev sib txhuam coefficient me me, kev thauj mus los yog siab.
(5) Kev ua tau zoo ntawm cov tshuaj lom neeg: cov khoom no tsis muaj tshuaj lom, tsis qab, acid thiab alkali tsis kam, corrosion kuj, ntau yam kev siv.PPR feem ntau yog siv rau zaub mov, dej haus, dej kais,
Cov dej ntshiab thiab lwm cov kav dej ua kua thiab cov khoom siv nrog kev huv huv, kuj tuaj yeem siv rau cov kav dej thiab cov khoom siv nrog me ntsis corrosion;
RPP, UPVC, PVDF, CPVC yog tsuas yog siv rau cov kua (gas) ntws ntawm cov kua qaub, muaj zog alkali thiab tov kua qaub nrog muaj zog corrosive.
(6) yooj yim installation, zoo sealing: cov khoom yog lub teeb nyob rau hauv zoo, kev siv ntawm kev sib txuas los yog vuam, ua tiav cov yeeb nkab fittings, yooj yim siv, zoo sealing, tsis tshua muaj zog siv.
Yas pob valve nws tus kheej yog cov yam ntxwv tseem ceeb ntawm cov qauv compact, txhim khu kev qha sealing, yooj yim qauv, yooj yim txij nkawm, sealing nto thiab kheej kheej feem ntau nyob rau hauv lub xeev kaw, tsis yooj yim rau nruab nrab erosion, yooj yim khiav lag luam thiab txij nkawm, muaj feem xyuam rau dej, hnyav, acid. thiab roj, xws li kev ua haujlwm nruab nrab, tab sis kuj yog qhov tsim nyog rau kev ua haujlwm ntawm kev tshaj tawm, xws li oxygen, hydrogen peroxide, methane thiab ethylene, Nws yog dav siv hauv ntau yam lag luam.Lub pob valve lub cev tuaj yeem ua ib qho lossis ua ke.
