Umsebenzi we-Valve Gasket & Umhlahlandlela wokusebenzisa

Ama-gasket we-valve aklanyelwe ukukhandela ukuvuza okubangelwa kugandeleleka, ukugqwala, kanye nokunwebeka/ukuncipha hlangana neengcenye. Nanyana pheze zoke zifakweukuxhumana's amavalvu atlhoga ama-gasket, ukusetjenziswa kwawo nokuqakatheka kwawo kuyahluka ngokuya ngomhlobo wevalvu nomklamo. Esigabeni lesi,I-TWSuzokuhlathulula iindawo zokufakwa kwevalvu nokukhethwa kwepahla ye-gasket.

I. Ukusetjenziswa okuphambili kwama-gasket kuse-flange joint yokuhlanganiswa kwevalvu.

Ivalvu esetjenziswa khulu

1. Ivalvu yesango
2. I-Globe Valve
3. Ivalvu ye-butterfly(khulukhulu i-valve ye-butterfly ene-flanged ne-double eccentric)
4. Hlola ivalvu

Emavalvu la, i-gasket ayisetjenziselwa ukulawula ukugeleza nofana ukuvala ngaphakathi kwevalvu ngokwayo, kodwana ifakwa hlangana namafletjhi amabili (hlangana neflentjhi yevalvu ngokwayo neflentjhi yepayipi). Ngokuqinisa amabhawudo, amandla wokubopha aneleko akhiqizwa ukwenza isivalo esijameleko, ukukhandela ukuvuza kwe-medium ekuhlanganisweni. Umsebenzi wayo kukuvala iinkhala ezincani ezingalingani hlangana nama-flange ensimbi amabili, ukuqinisekisa ukuvala okuyi-100% ekuhlanganisweni.

II.Ukusetjenziswa kwe-Gasket ku-Valve "Isembozo se-Valve"

Amavalvu amanengi aklanyelwe abe nemizimba yamavalvu ehlukileko kanye namakhava ukwenzela bona kube lula ukutlhogonyelwa kwangaphakathi (isib., ukufaka iinhlalo zamavalvu, amavalvu wediski, nofana ukususa iimvuthuluka), ebese zibotjhwa ndawonye. I-gasket nayo iyatlhogeka ekuhlanganisweni lokhu ukuqinisekisa ukuvalwa okuqinileko.

1. Ukuhlangana hlangana kwesivalo sevalvu nomzimba wevalvu wevalvu yesango nevalvu ye-globe kuvame ukutlhoga ukusetjenziswa kwe-gasket nofana i-O-ring.
2. I-gasket kulendawo nayo isebenza njengesivalo esijameleko ukukhandela bona umphakathi ungavuzi usuka emzimbeni wevalvu ungene emoyeni.

III. I-gasket ekhethekileko yemihlobo ethileko yamavalvu

Amanye amavalvu afaka i-gasket njengengcenye yomhlangano wawo wokuvala, owenzelwe ukuhlanganiswa ngaphakathi kwesakhiwo samavalvu.

1. Ivalvu ye-butterfly-i-valve seat gasket

• Isihlalo se-butterfly valve empeleni siyi-ring gasket, ecindezelwe ebodeni langaphakathi lomzimba we-valve nofana ifakwe eduze ne-butterfly disc.
• Lokha ivivaneidiskiivala, igandelela isihlalo sevalvu ukwenza isivalo esinamandla (njengevivaneidiskiiyajikeleza).
• Into leyo ivamise ukuba yirabha (isib., i-EPDM, i-NBR, i-Viton) nofana i-PTFE, eyenzelwe ukwamukela ubujamo beendaba ezihlukahlukeneko kanye namazinga womtjhiso.

2. Ivalvu yebholo-Valve Seat Gasket

• Isihlalo se-valve se-ball valve nayo mhlobo we-gasket, evamise ukwenziwa ngezinto ezifana ne-PTFE (i-polytetrafluoroethylene), i-PEEK (i-polyetheretherketone), nofana amapulasitiki aqinisiweko.
• Inikela ngokuvala hlangana nebholo nomzimba wevalvu, isebenza kokubili njengesivalo esijameleko (ngokuhlobana nomzimba wevalvu) kanye nesivalo esiguquguqukako (ngokuhlobana nebholo elijikajikako).

IV. Ngimaphi amavalvu angasetjenziswa khulu nama-gasket?

1. Amavalvu ahlanganisiwe: Umzimba wevalvu uhlanganiswe ngqo epayipini, okuqeda isidingo samaflentshi nama-gasket.
2. Amavalvu aneenhlanganisela ezineentambo: Ngokuvamileko asebenzisa ukuvala okuneentambo (njengetheyiphu yezinto ezisetjenziswako nofana isivalo), ngokuvamileko ukuqeda isidingo samagasketi.
3. Amavalvu we-monolithic: Amanye amavalvu webholo abiza kancani nofana amavalvu akhethekileko anomzimba wevalvu ongakwazi ukuhlukaniswa, lokho-ke angenayo i-gasket yokuvala ivalvu.
4. Amavalvu anama-O-ring nofana ama-gasket ahlanganiswe ngensimbi: Ekusetjenzisweni okune-pressure ephezulu, okutjhisa khulu, nofana okukhethekileko, iinsombululo ezithuthukisiweko zokuvala zingathatha indawo yama-gasket avamileko angasiwo wensimbi.

V. Isifinyezo:

I-valve gasket mhlobo we-elementi yokuvala ikhiye yokusika, isetjenziswa khulu ekuhlanganiseni amapayipi wamavalvu ahlukahlukeneko, begodu isetjenziselwa nokuvala ivalvu yamavalvu amanengi. Ekukhetheni, kuyatlhogeka ukukhetha into efaneleko ye-gasket bese ibumba ngokuya ngohlobo lwevalvu, imodi yokuxhumana, isilinganiso, izinga lokushisa kanye nomfutho.
