Umsebenti weValve Gasket & Umhlahlandlela Wekusebentisa

Ema gaskets emavalvu aklanyelwe kuvikela kuvuza lokubangelwa kucindzeteleka, kugcola, kanye nekwandziswa kwekushisa/kuncipha emkhatsini wetincenye. Ngesikhatsi cishe bonkhe flanged .kuxhumana's emavalvu adzinga ema-gaskets, kusetjentiswa kwawo lokutsite kanye nekubaluleka kwawo kuyahluka ngeluhlobo lwevalvu kanye nekuklama. Kulesigaba, .TWSutawuchaza tikhundla tekufakwa kwevalve kanye nekukhetsa tintfo te-gasket.

I. Kusetjentiswa lokuyinhloko kwema-gaskets kusekuhlanganeni kwe-flange kwekuhlanganiswa kwevalve.

Ivalve levame kusetjentiswa kakhulu

1. Ivalvu yeLisango
2. Ivalvu Yemhlaba
3. Ivalvu yevivane(ikakhulukati i-valve yevivane lesemkhatsini nalephindvwe kabili)
4. Hlola ivalvu

Kulama valve, le gasket ayisetjentiswa kulawula kugeleta noma kuvala ngaphakatsi kwe valve yona, kepha ifakwa emkhatsini wema flanges lamabili (emkhatsini we flange ye valve yona kanye ne flange yephayiphi). Ngekucinisa emabhawudi, emandla lanele ekucindzetela akhicitwa kwenta luphawu lolumile, kuvikela kuvuza kwemkhatsi lapho kuxhumana khona. Umsebenti wayo kugcwalisa tikhala letincane letingalingani emkhatsini wetindzawo letimbili te flange yensimbi, kucinisekisa kuvala lokungu 100% lapho kuhlangana khona.

II.Kusetjentiswa kweGasket kuValve “Simbonyo Sevalve”

Emavalvu lamaningi aklanyelwe ngemitimba yemavalvu lehlukene kanye netimbonyo kwentela kugcinwa lokulula ngekhatsi (sib., kushintja tindzawo temavalvu, emavalvu ema disc, noma kuhlanta imfucumfucu), lese iyahlanganiswa ngemabhawudi. I-gasket nayo iyadzingeka kulokuxhumana kucinisekisa kuvalwa lokucinile.

1. Kuhlangana emkhatsini wesivalo sevalve kanye nemtimba wevalve wevalve yesango kanye nevalve yemhlaba kuvame kudzinga kusetjentiswa kwe gasket noma i-O-ring.
2. Le gasket kulesikhundla iphindze isebente njengesivalo lesimile kuvikela le medium kutsi ingavuti kusuka emtimbeni we valve iye emkhatsini.

III. I-gasket lekhetsekile yetinhlobo letitsite temavalvu

Lamanye emavalvu afaka le gasket njengencenye yekuhlangana kwawo kwekuvala lokuyinhloko, lokwentelwe kutsi kuhlanganiswe ngaphakatsi kwesakhiwo sevalvu.

1. Ivalvu yevivane-valve situlo gasket

• Sihlalo se valve ye butterfly empeleni siyi gasket yendandatho, lecindzetelwa eludongeni lwangekhatsi lwemtimba we valve noma ifakwe eceleni kwe disc ye butterfly.
• Ngesikhatsi luvivane .idiskikuvala, kucindzetela i-gasket yesihlalo sevalve kute yakhe luphawu lolushintjashintjako (njengobe luvivaneidiskiiyajikeleta).
• Lentfo ivame kuba yinjoloba (sib., EPDM, NBR, Viton) noma iPTFE, leyentelwe kufaka imidiya leyehlukene kanye netimo tekushisa.

2. Ivalvu yelibhola-I-Gasket Yesihlalo Sevalve

• Sihlalo sevalvu sevalvu yelibhola siphindze sibe luhlobo lwe-gasket, levame kwentiwa ngetintfo letifana ne-PTFE (i-polytetrafluoroethylene), i-PEEK (i-polyetheretherketone), noma emapulasitiki lacinisiwe.
• Iniketa sivalo emkhatsini webhola kanye nemtimba we valve, isebenta kokubili njengesivalo lesimile (lesihlobene nemtimba we valve) kanye nesivalo lesishintjashintjako (lesihlobene nelibhola lelijikeletako).

IV. Ngumaphi emavalvu langasetjentiswa ngalokuvamile nema-gasket?

1. Emavalvu lashiselwe: Umtimba wevalve ushiselwe ngco kuphayiphi, kucedza sidzingo sema flanges kanye nema gaskets.
2. Emavalvu lanekuhlanganiswa lokunetintsambo: Ngalokuvamile kusebentisa kuvala lokunetintsambo (njengetheyiphu yetintfo letiluhlata noma i-sealant), ngalokuvamile kucedza sidzingo sema-gaskets.
3. Emavalvu eMonolithic: Lamanye emavalvu ebhola labita kancane noma emavalvu lakhetsekile anemtimba wevalvu lohlanganisiwe longeke ukhishwe, ngaleyondlela ashoda nge gasket yekuvala ivalvu.
4. Emavalvu lane-O-rings noma ema-gaskets lagocotwe ngensimbi: Ekusebentiseni lokunemfutfo lomkhulu, lokushisa kakhulu, noma lokukhetsekile-lokusemkhatsini, tisombululo tekuvala letisezingeni lelisetulu tingatsatsa sikhundla sema-gaskets lavamile langasiwo ensimbi.

V. Sifinyeto:

Valve gasket luhlobo jikelele ukusika ukhiye kuvala element, it kusetjentiswa kakhulu uxhumano emapayipi valves ezahlukene flange, futhi kusetjentiswa valve cover ukuvala emavalvu amaningi. Ekukhetseni, kuyadzingeka kutsi ukhetse tintfo letifanele te-gasket bese tiyakheka ngekuya kweluhlobo lwe-valve, imodi yekuxhumana, lesemkhatsini, lokushisa kanye nemfutfo.
