Izindaba - I-Polyurethane Knife Gate Valve Egcwele Ulayini Ongaguquki

Iyini i-valve yesango lommese we-polyurethane

I-valve yesango lommese we-polyurethaneibhekisela ku-valve yesango lommese enophawu lwesihlalo se-valve ye-polyurethane.I-Polyurethane (PU)Inezici zokumelana namafutha, ukumelana nokuguguleka, ukumelana nokushisa okuphansi, ukumelana nokuguga, ubulukhuni obuphezulu, ukuguquguquka okuhle kanye nokusebenza okuhle kokulwa nobuthi. Ivame ukusetshenziselwa izinhlayiya zokuqina okuphezulu kanye namapayipi aphakathi aqukethe igesi noketshezi. Isebenza kahle ekuvaleni kanye nokumelana nokuguguleka okunamandla aphezulu.

I-Polyurethane yaziwa ngokuthi “irabha engagugi”. Ukumelana kwayo namafutha akuphansi kunokwerabha ye-nitrile futhi kufana nerabha ye-polysulfide. Ifaneleka kakhulu kumapayipi ahlukahlukene aphakathi nendawo adinga ukuvalwa okuphezulu kanye nokuguguleka kwezinhlayiya ezinamandla aphezulu.

Izici Zokuklama:

I-Polyurethane Knife Gate Valveokwenza kube ngenye yezinto ezingcono kakhulu ezingamelani nokuklwebheka. I-Polyurethane Knife Gate Valve yethu (NSW) igcwele i-urethane esezingeni eliphezulu, edlula kakhulu isikhathi sokuguguleka kwerabha yensini nanoma iyiphi enye i-liner ethambile, noma izinto zesikhafu.

isithombe001

1.Akukho ukuvuza: Umzimba we-valve ye-urethane egcwele kanye ne-molded elastomer gate seal kuvimbela ukuvuza unomphela kokubili ukuvalwa kwe-valve kanye nomzimba we-valve uqobo ngesikhathi sokusebenza.

2.Isikhathi eside sokuguguleka: Ama-urethane liner aqinile amelana nokuklwebheka asezingeni eliphezulu, kanye namasango aqinile ommese ongagqwali kanye nomklamo oyingqayizivele wevalvu ngokwayo kunikeza impilo yesevisi ende kakhulu.

3.Ukuvala okuqondene nezinhlangothi ezimbiliUma kwenzeka ukugeleza kokubuyela emuva, i-NSW ingasetshenziswa njengesivikelo.

4.Idizayini ezihlanzayo: Ngesikhathi sokuvala ivalvu, isango lommese eligobile liqondisa kabusha i-slurry egelezayo iye esihlalweni se-urethane liner esigobile, idale i-turbulence futhi ikhulise ukugeleza bese ikhipha i-slurry phansi kwe-urethane njengoba isango lihlala esihlalweni.

5. Ukwakhiwa kabusha okulula: Uma ekugcineni kudingeka ukwakhiwa kabusha, izingxenye ezigugile (ama-urethane, izivalo zamasango, amasango ommese) zingashintshwa zonke ensimini. Imizimba yamavalvu nezinye izingxenye zingasetshenziswa kabusha.

Izinketho

1. Indandatho Yesihlalo (Ama-Liner):Izinhlobo ze-urethanes ziyatholakala.

2. Amasango E-Valve:Amasango e-SS304 ane-chromium eqinile ajwayelekile. Amanye ama-alloy ayatholakala (SS316, 410, 416, 17-4PH…) Kukhona nezingubo zokugqoka zamasango ongazikhethela.
