Ivalve engabuyiyo yeOli, iGesi kunye nemibhobho yeMichiza

I-disc iphakamisa ngqo esihlalweni xa uxinzelelo lungena, kwaye luhlala phantsi lodwa xa umgca ungasebenzi. Akukho mithombo okanye izikhonkwane zehinge zokudinwa kwaye akukho kupakishwa okuvuza, yiyo loo nto ibambelela ngokuqinileyo kumphunga, kwibhoyila yokutya kunye nezinye iinkonzo apho iivalvu eziqhelekileyo zokujonga zidla ngokuncokola okanye zithontsize ngokuhamba kwexesha.

Iza ifakelwe iziphelo eziphothiweyo ezithi ibholithi ngqo emgceni. Kwiinjineli eziqhuba amanzi, umphunga okanye iinkqubo zomoya ezifuna nje ivalve yokutshekisha banokungena kwaye balibale, oku kukhetho oluthe ngqo.

Yintoni eyenziwa yivalve yokuphakamisa

Imisa umva. Xa impompo icima, umgca ucinezelekile, okanye ivalve ivale phambi kwakho, ulwelo lutyhala ngasemva kwaye luyakwazi ukujikelezisa impompo umva, ihamile imitha, okanye ukulahla ulwelo apho lungekhoyo. I-valve yokujonga i-valve yokuphakamisa iyayeka yonke loo nto ngaphambi kokuba iqale: ukuhamba phambili kuphakamisa i-disc kwisihlalo, kwaye umzuzu wokuhamba uyancipha, i-disc iwa ngasemva ngobunzima kwaye itywine umgca.

Iimpawu eziphambili

Indlela i-lift check design yahluke ngayo

I-disc ihamba ngokuthe tye phezulu nangaphantsi, ikhwele i-flow direction

Ivala ngomxhuzulane, ngoko kungabikho ntwasahlobo yokudinwa kwaye akukho phini lokuhombisa eliza kuguga

Amalungu amancinci ashukumayo athetha ukugcinwa okuncinci kwaye okuncinci kunokusilela kwiminyaka yenkonzo

Isebenza ngokuzolileyo kwisondlo somphunga kunye nebhoyila, apho iitshekhi ezigcwele intwasahlobo zidla ngokuncokola

Uhambo olufutshane kunye neentshukumo ezikhawulezayo zikwaphungula umngcipheko wehamile yamanzi ekujikekeni ngesiquphe

Yenziwe ngantoni

Umzimba : Intsimbi yekhabhoni eqinileyo, eyakhelwe ukuthatha i-spikes yoxinzelelo kunye nemijikelo ephindaphindiweyo evulekileyo / evaliweyo ngaphandle kokuqhekeka

I-Disc & seat : ihambelana nenkonzo yakho yokucoca, ukuvalwa okuqinileyo; i-stainless trim ekhoyo kubushushu obuphezulu okanye imidiya eyonakalisa kancinci

Ivalve nganye isitampu ngenombolo yobushushu, ibakala lemathiriyeli, ubungakanani kunye neklasi yoxinzelelo, ukuze ukwazi ukuyilanda ukusuka kwintsimbi yentsimbi ukuya kumgca wakho. Ii-MTCs ezibonelelwa ngayo yonke iodolo.

Uqhagamshelo kunye nofakelo

Iziphelo ezijijelwe ngebhawuthi ezithe ngqo kumgca; iziphelo ezinemisonto ezifumanekayo zokhetho olubambeneyo, lokutshixa

Inyuka kakuhle kwimigca ethe nkqo, kuba idiski ihamba phezulu nasezantsi kunokuba ijiwuze emacaleni

Ubuso obusemgangathweni RF / RTJ; akukho welding efunekayo - vula kwaye uphakamise ivalve xa ulungisa

Apho ifumana ukugcinwa kwayo

Ukutya kwe-Steam kunye nebhoyila (indawo yokukhangela i-classic lift check), iinkqubo zomoya ezicinezelekileyo, amanzi kunye nolwelo lwenkqubo ecocekileyo ekungafuneki ibuye ngasemva, imigca yokukhupha impompo efuna ukukhuselwa kujikelezo olubuyela umva, kunye nemibhobho yemizi-mveliso ngokubanzi kwiinkonzo ezingarhabulisi.

Iinkcazo zobugcisa ngokujonga nje

Uluhlu lobungakanani: DN15 - DN400, inkulu xa uceliwe

Iqondo loxinzelelo: PN16 / PN25 / PN40, okanye ASME Class 150 / 300 / 600

Uqhagamshelo : i-flanged (RF / RTJ) okanye intambo

Izinto eziphathekayo: intsimbi yekhabhoni eqinileyo, i-A105 / WCB kunye nabanye

Imidiya : amanzi, umphunga, umoya oxinanisiweyo, ulwelo olucociweyo olungarhabulisi

Imigangatho: I-API, i-ASME kunye nemigangatho ehambelana ne-GB

Umlinganiselo ochanekileyo uqinisekisiwe ngokuchasene neendaba zakho, uxinzelelo kunye nobushushu - asiyingeni imodeli yegeneric kumgca wakho.

Indlela yokukhetha imathiriyeli

Umphunga, amanzi okanye umoya oxinanisiweyo usixelela ukuba ufuna ukwakha ubushushu obuphezulu; nokuba iyadleka ithatha isigqibo sokuba sitshintshisa isitrim kwi-stainless; Uxinzelelo kunye nobushushu bugqiba ngomzimba kunye nenqanaba lesihlalo. Sithumelele i-media yakho, i-pH kunye noluhlu lobushushu obusebenzayo, kwaye ubunjineli buya kuhlanganisa eyona trim inexabiso eliphezulu kuwe.

Umgangatho, iwaranti kunye nokuhanjiswa

Ivalve nganye idlula iqokobhe le-hydrostatic kunye novavanyo lokuvuza kwesitulo phambi kokuba ithunyelwe ngenqanawa, kwaye uvavanyo lomntu wesithathu luyaxhaswa. Ii-MTC, iingxelo zovavanyo, imizobo yomlinganiselo kunye nencwadana yokusebenza iza nomyalelo. I-Flange kunye neziphelo zomsonto zikhuselwe ukuhamba, kwaye ubungakanani bentsimbi yekhabhoni eqhelekileyo bugcinwe ngokohlobo lweflanged kunye nemisonto ephothiweyo ngenqanawa ngokukhawuleza.

Yintoni esahlulayo

Uninzi lwababoneleli bathumela isatifikethi se-hydrostatic yeqokobhe kwaye bayibize ngokuba lusuku. Sabelana ngengxelo yovavanyo lokuvuza kwesitulo, kuba lelo linani elikuxelela ukuba ivalve yokutshekisha iya kubamba. Kwaye kwisondlo somphunga okanye kwibhoyila, sicebisa ukuba kulungiswe inkonzo yakho yokwenyani endaweni yokutyhala imodeli yegeneric.

Imibuzo ebuzwa qho

Q1. Phakamisa itshekhi vs ujingi jonga?

I-disc yokukhangela i-lift ishukuma ngokuthe ngqo phezulu naphantsi kwaye ivale ngomxhuzulane; itshekhi yokujingi ijinga kwihenjisi. Uhlobo lokuphakamisa lutywina ngokufanelekileyo kwi-steam kunye ne-boiler feed, ngelixa uhlobo lwe-swing lunokumelana nokuhamba okuphantsi kwemigca emikhulu, ephezulu.

Q2. Ngaba inokufakwa ngokuthe nkqo?

Ewe. Ngenxa yokuba i-disc ihamba phezulu nasezantsi, ukunyuswa ngokuthe nkqo kuhambelana nesalathiso sayo sendalo sokuvala; ukunyuswa okuthe tyaba kuyasebenza.

Q3. Ngaba kukho inguqulelo elayishwe entwasahlobo?

Ewe. Uhlobo oluqhelekileyo luvalwa ngumxhuzulane; kwimigca yoxinzelelo oluphantsi olufuna ukukhawuleza, ukuvaleka ngokukhawuleza, songeza umthombo wokuncedisa i-disc.

Q4. Ngaba ibangela ihamile yamanzi?

I-disc yokuphakamisa ivala ngokukhawuleza kunye nohambo olufutshane, olunceda ukusika ukubuya kwe-backflow. Izihlalo zethu zivavanyiwe ukuvuza, ngoko xa zivaliwe zihlala ziqinile.

Q5. Ngaba ndifuna i-welding ukuyifaka?

Hayi. Iinguqulelo ezine-Flanged zihambelana ne-gasket kunye ne-torque iibholithi; iinguqulelo ezinemisonto zijija ngqo. Xa ulungisa ngokutsha uyakhulula kwaye uphakamise ivalve ngaphandle kokusika umbhobho.

Q6. Ngaba ungabonelela ngezatifikethi zemathiriyeli?

Ewe. Ii-MTCs, iingxelo zovavanyo, imizobo yomlinganiselo kunye nenqanawa yokusebenza ngesandla enomyalelo, kunye nokuhlolwa kobungqina bomntu wesithathu kuyafumaneka.

Q7. Lithini ixesha lokuhamba?

Ubungakanani obuqhelekileyo bentsimbi yekhabhoni bugcinwe kwaye buthunyelwa ngokukhawuleza; izinto ezingekho mgangathweni okanye iklasi yoxinzelelo olukhethekileyo idinga ixesha lokuvelisa - thumela i-specs kwaye siyaqinisekisa.

Q8. Ndingayifumana isampuli yokuvavanya kuqala?

Ewe. Sixhasa ii-odolo zesampulu kwiisayizi eziqhelekileyo ukuze uqinisekise phambi komyalelo wesambuku, wehlise umngcipheko wokhetho lwakho.
