Ivaluvu Engabuyi Emapayipini Kawoyela, Igesi kanye Namakhemikhali

I-disc iphakama iqonde esihlalweni lapho ingcindezi ingena, bese izinza yodwa uma ulayini ungasebenzi. Azikho iziphethu noma izikhonkwane zamahinge zokukhathala futhi azikho ukupakishwa okuzovuza, yingakho ibambelela ngokuqinile kusitimu, okuphakelayo kubhayela nezinye izinkonzo lapho ama-valve okuhlola avamile evame ukuxoxa noma aconse ngokuhamba kwesikhathi.

Iza ifakwe iziphetho ezicashile ezibhawodi ngqo emugqeni. Konjiniyela abasebenzisa amanzi, isitimu noma amasistimu omoya abafuna nje ivalve yesheke abangangena bese bekhohlwa, lokhu ukukhetha okuqondile.

Okwenziwa yi-valve yokuhlola i-lift

Imisa ukubuyela emuva. Uma iphampu ivaleka, umugqa uyadambisa, noma ivalvu ivaleka ngaphambi kwakho, uketshezi luhlehla luhlehle futhi lungazungeza iphampu lihlehle, lisando imitha, noma lulahle uketshezi lwenqubo lapho lungekho khona. I-valve yokuhlola i-lift imisa konke lokho ngaphambi kokuba iqale: ukugeleza phambili kuphakamisa i-disc esihlalweni, futhi umzuzu wokugeleza wehla, i-disc iwela emuva ngamandla adonsela phansi bese ivala umugqa.

Izimfanelo Ezibalulekile

Indlela umklamo wokuhlola i-lift uhluke ngayo

I-disc ihamba iqonde phezulu naphansi, igibele isiqondiso sokugeleza

Ivalwa ngamandla adonsela phansi, ngakho-ke akukho mthombo wokukhathala futhi akukho phini lehinge elizoguga

Izingxenye ezihambayo ezimbalwa zisho ukunakekelwa okuncane kanye nezincane ezingahluleka phakathi neminyaka yesevisi

Isebenza ngokuthula kokuphakelayo kwesitimu nokubhayela, lapho amasheke alayishwe intwasahlobo evamise ukuxoxa

Uhambo olufushane kanye nesenzo esisheshayo futhi kunciphisa ubungozi besando samanzi ekuguqulweni kokugeleza okungazelelwe

Yakhiwe ngani

Umzimba : insimbi ye-carbon steel, eyakhelwe ukuthatha ama-spikes okucindezelayo kanye nemijikelezo ephindaphindiwe evulekile / evaliwe ngaphandle kokuqhekeka

I-Disc & seat : ifaniswe nesevisi yakho ukuze kuvalwe okuhlanzekile, okuqinile; i-stainless trim itholakalela izinga lokushisa eliphezulu noma imidiya egqwala kancane

Wonke ama-valve agxivizwe ngenombolo yokushisa, ibanga lempahla, usayizi nesigaba sokucindezela, ukuze ukwazi ukuyilandelela ukusuka emshinini wensimbi ukuya kulayini wakho. Ama-MTC ahlinzekwa ngawo wonke ama-oda.

Ukuxhumana nokufakwa

Ibhawodi ephethe iziphetho eziqondile iqonde emugqeni; imiphetho ewuchungechunge iyatholakala ngenketho ehlangene, yokuklipha

Igibeleka kahle emigqeni eqondile, ngoba idiski ihamba phezulu naphansi kunokuba ijike ibheke emaceleni

Ubuso obujwayelekile RF / RTJ; akukho ukushisela okudingekayo - vula futhi uphakamise i-valve lapho ulungisa kabusha

Lapho ithola khona ukugcina kwayo

Isiphakeli se-steam nebhayela (indawo yokuhlola i-lift yakudala), amasistimu omoya acinene, amanzi noketshezi lwezinqubo ezihlanzekile okungafanele agezele emuva, imigqa yokukhipha impompo edinga ukuvikeleka ekuzungeziseni okubuyela emuva, kanye namapayipi avamile embonini kumasevisi angahubi.

Imininingwane yobuchwepheshe ngokubuka nje

Ibanga losayizi : DN15 - DN400, elikhudlwana ngesicelo

Isilinganiso sokucindezela: PN16 / PN25 / PN40, noma ASME Class 150 / 300 / 600

Uxhumano: i-flanged (RF / RTJ) noma intambo

Impahla yomzimba: insimbi eqinile ye-carbon, i-A105 / WCB nabanye

Imidiya : amanzi, isitimu, umoya ocindezelwe, uketshezi oluhlanzekile olungaqhumi

Amazinga: I-API, i-ASME namazinga we-GB afanayo

Isilinganiso esiqondile siqinisekiswa ngokumelene nemidiya yakho, ingcindezi nezinga lokushisa - asilingani imodeli ejwayelekile emugqeni wakho.

Indlela yokukhetha impahla

Isitimu, amanzi noma umoya ocindezelwe usitshela ukuthi udinga isakhiwo esinezinga lokushisa eliphezulu; ukuthi iyagqwala yini inquma ukuthi ngabe sishintshanisa u-trim ku-stainless; ingcindezi nezinga lokushisa kunquma izinga lomzimba nesihlalo. Sithumelele imidiya yakho, i-pH kanye nebanga lokushisa elisebenzayo, futhi ubunjiniyela buzokuhlanganisela ukunquma okungabizi kakhulu kuwe.

Ikhwalithi, iwaranti kanye nokulethwa

Wonke ama-valve adlula ukuhlolwa kwegobolondo le-hydrostatic kanye nokuvuza kwesihlalo ngaphambi kokuthi kuthunyelwe, futhi nokuhlolwa kofakazi benkampani yangaphandle kuyasekelwa. Ama-MTC, imibiko yokuhlola, imidwebo yobukhulu kanye nebhukwana lokusebenza kufika ne-oda. Iziphetho ze-Flange nentambo zivikelwe ukuze zihambe, futhi osayizi bensimbi ye-carbon ejwayelekile bafakwa esitokisini ngakho izinguqulo ezinemicu nezinguqulo zithunyelwa ngokushesha.

Yini esehlukanisa

Abahlinzeki abaningi bathumela isitifiketi se-hydrostatic yegobolondo futhi bayibize ngosuku. Sabelana ngombiko wokuhlola ukuvuza kwesihlalo futhi, ngoba leyo inombolo ekutshela ngempela ukuthi i-valve yokuhlola izobamba yini. Futhi ngokuphakelayo kwesitimu noma kubhayela, sincoma ukusika kwesevisi yakho yangempela esikhundleni sokuphusha imodeli ejwayelekile.

Imibuzo ejwayelekile ukubuzwa

Q1. Phakamisa isheke vs isheke lokushwiba?

I-lift check disc ihamba iqonde phezulu naphansi bese ivala amandla adonsela phansi; isheke lokujikijela lijika kuhinji. Uhlobo lokuphakamisa luvala kahle kakhulu okuphakelayo kwesitimu nokubhayela, kuyilapho uhlobo lokushwiba lunokumelana nokugeleza okuphansi kwemigqa emikhulu, egeleza kakhulu.

Q2. Ingabe ingafakwa iqonde phezulu?

Yebo. Ngenxa yokuthi i-disc ihamba phezulu naphansi, ukukhweza okuqondile kufanelana nendlela yayo yokuvala yemvelo; ukukhweza okuvundlile nakho kuyasebenza.

Q3. Ingabe ikhona inguqulo elayishwe entwasahlobo?

Yebo. Uhlobo olujwayelekile luvala amandla adonsela phansi; emigqeni enengcindezi ephansi edinga ukuvala okusheshayo, okuzwela kakhulu, sengeza isiphethu ukusiza idiski.

Q4. Ingabe ibangela isando samanzi?

I-lift disc ivala ngokushesha ngokuhamba okufushane, okusiza ukunqamula ukugeleza okubuyela emuva. Izihlalo zethu zihloliwe ukuvuza, ngakho uma sezivaliwe zihlala ziqinile.

Q5. Ingabe ngidinga i-welding ukuze ngiyifake?

Cha. Izinguqulo ezine-Flanged zilingana ne-gasket futhi zifake ama-torque amabhawodi; izinguqulo ezinemicu zigoqa ziqonde. Lapho ulungisa kabusha uyaqaqa futhi uphakamise i-valve ngaphandle kokusika ipayipi.

Q6. Ungakwazi ukunikeza izitifiketi zempahla?

Yebo. Ama-MTC, imibiko yokuhlola, imidwebo yobukhulu kanye nomkhumbi wokusebenza owenziwe nge-oda, nokuhlolwa kofakazi benkampani yangaphandle kuyatholakala.

Q7. Siyini isikhathi sokuhola?

Amasayizi ensimbi ye-carbon ejwayelekile afakwa futhi athunyelwa ngokushesha; izinto ezingajwayelekile noma isigaba sokucindezela okukhethekile sidinga isikhathi sokukhiqiza — thumela imininingwane futhi siyaqinisekisa.

Q8. Ngingathola isampula ukuze ngihlole kuqala?

Yebo. Sisekela ama-oda amasampula kumasayizi ajwayelekile ukuze uqinisekise ngaphambi kwe-oda lenqwaba, wehlise ubungozi bokukhetha.
