Qhov qhib thiab kaw qhov (sphere) yog tsav los ntawm lub valve qia thiab tig ib ncig ntawm lub axis ntawm lub valve qia.Nws yog tsuas yog siv los txiav tawm lossis txuas qhov nruab nrab hauv cov kav dej, thiab tseem tuaj yeem siv rau kev hloov kho thiab tswj cov kua dej.Hom valve no feem ntau yuav tsum tau teeb tsa kab rov tav hauv cov kav dej.
Cov yam ntxwv ntawm cov yascompact pob valve:
(1) Kev ua haujlwm siab: kev ua haujlwm siab ntawm ntau yam ntaub ntawv tuaj yeem ncav cuag 1.0Mpa ntawm chav tsev kub.
(2) Kev khiav hauj lwm kub: PVDF kev khiav hauj lwm kub yog -20 ℃ ~ + 120 ℃;RPP kev khiav hauj lwm kub yog -20 ℃ ~ + 95 ℃;UPVC kev khiav hauj lwm kub yog -50 ℃ ~ + 95 ℃.
(3) Kev cuam tshuam zoo: RPP, UPVC, PVDF, CPVC muaj zog txhua yam thiab cuam tshuam.
(4) Tsis tshua muaj kua ntws tsis kam: du sab hauv phab ntsa ntawm cov khoom, me me kev sib txhuam coefficient, thiab siab conveying efficiency.
(5) Cov khoom siv tshuaj zoo heev: Cov khoom no tsis muaj tshuaj lom, tsis muaj ntxhiab, acid thiab alkali resistant, corrosion resistant, thiab muaj ntau yam kev siv.PPR feem ntau yog siv rau zaub mov, dej haus, dej kais dej,
Cov dej ntshiab thiab lwm cov kav dej ua kua thiab cov khoom siv huv si kuj tuaj yeem siv rau cov kav dej thiab cov khoom siv uas tsis muaj corrosiveness;
RPP, UPVC, PVDF, CPVC feem ntau yog siv rau kev ncig ntawm cov kua (gas) uas muaj zog corrosive acids, muaj zog alkalis thiab cov kua qaub sib xyaw.
(6) Yooj yim installation thiab airtightness zoo: cov khoom no yog lub teeb nyob rau hauv qhov hnyav, sib txuas los yog welded, ua tiav cov yeeb nkab fittings, kev tsim kho yooj yim, airtightness zoo, thiab kev siv zog tsawg.
Lub ntsiab nta ntawm lub pob valve yog nws cov qauv compact, txhim khu kev qha sealing, yooj yim qauv, thiab yooj yim txij nkawm.Lub sealing nto thiab spherical nto feem ntau raug kaw, tsis yooj yim rau eroded los ntawm nruab nrab, thiab yooj yim rau kev khiav lag luam thiab tswj.Nws yog tsim rau dej, kuab tshuaj, acids thiab natural gas.Qhov nruab nrab ua haujlwm kuj tseem haum rau nruab nrab nrog kev ua haujlwm hnyav, xws li oxygen, hydrogen peroxide, methane thiab ethylene, thiab lwm yam, uas tau siv dav hauv ntau yam lag luam.Lub pob valve lub cev tuaj yeem ua ib qho lossis ua ke.
