Aho cheque valve ikwiye.

Intego yo gukoresha cheque ya cheque ni ukurinda gusubira inyuma kwikigereranyo, kandi cheque valve isanzwe ishyirwa kumasoko ya pompe.Mubyongeyeho, cheque valve nayo igomba gushyirwaho kumasoko ya compressor.Muri make, kugirango wirinde gutembera kwinyuma, hagomba gushyirwaho valve igenzura kubikoresho, ibikoresho cyangwa umuyoboro.

Mubisanzwe, vertical lift igenzura valve ikoreshwa kumiyoboro itambitse hamwe na diameter nominal ya 50mm.Kugenzura neza-kugenzurwa na valve irashobora gushyirwaho kumirongo itambitse kandi ihagaritse.Umuyoboro wo hasi usanzwe ushyizwe gusa kumuyoboro uhagaze wa pompe yinjira, kandi urwego rutemba ruva hasi rugana hejuru.

Swing cheque valve irashobora gukorwa mumuvuduko mwinshi wakazi, PN irashobora kugera kuri 42MPa, na DN nayo irashobora gukorwa nini cyane, ntarengwa irashobora kugera kuri 2000mm.Ukurikije ibikoresho bitandukanye byigikonoshwa hamwe na kashe, irashobora gukoreshwa muburyo ubwo aribwo bwose bukora hamwe nubushyuhe bwo gukora.Ikigereranyo ni amazi, amavuta, gaze, ibintu byangirika, amavuta, ibiryo, imiti, nibindi. Ubushyuhe bwakazi bwikigereranyo buri hagati ya -196 ~ 800 ℃.

Umwanya wo kwishyiriraho wa swing cheque valve ntugarukira, mubisanzwe ushyirwa kumuyoboro utambitse, ariko urashobora no gushyirwa kumuyoboro uhagaze cyangwa umuyoboro uhengamye.

Igihe cyakoreshwa cyo kugenzura ikinyugunyugu ni umuvuduko muke na diameter nini, kandi igihe cyo kwishyiriraho ni gito.Kuberako umuvuduko wakazi wikinyugunyugu kinyugunyugu ntushobora kuba hejuru cyane, ariko diameter nominal irashobora kuba nini cyane, ishobora kugera kuri mm 2000 zirenga, ariko umuvuduko wizina uri munsi ya 6.4MPa.Kugenzura ikinyugunyugu birashobora gukorwa muburyo bwa wafer, busanzwe bushyirwa hagati yibice bibiri byumuyoboro muburyo bwo guhuza wafer.

Imyanya yo kwishyiriraho ikinyugunyugu ntigishobora kugarukira, irashobora gushyirwaho kumuyoboro utambitse, umuyoboro uhagaze cyangwa umuyoboro uhengamye.

Diaphragm igenzura valve ikwiranye nimiyoboro ikunda inyundo.Diaphragm irashobora gukuraho neza inyundo y'amazi iterwa no kugaruka kwinyuma.Kubera ko ubushyuhe bwakazi hamwe nigitutu cyimikorere ya diaphragm igenzura valve igarukira kubintu bya diafragm, mubisanzwe bikoreshwa mumiyoboro yumuvuduko muke nubushyuhe busanzwe, cyane cyane kumiyoboro y'amazi.Mubisanzwe, ubushyuhe bwakazi buringaniye buri hagati ya -20 ~ 120 ℃, kandi igitutu cyakazi kiri munsi ya 1.6MPa, ariko igenzura rya diaphragm rishobora kugera kuri diameter nini, kandi DN ntarengwa irashobora kurenga 2000mm.

Diaphragm igenzura valve yakoreshejwe cyane mumyaka yashize kubera imikorere yayo itagira amazi, imiterere yoroshye hamwe nigiciro gito cyo gukora.

Igenzura ry'umupira rifite imikorere myiza yo gufunga, gukora neza no kurwanya inyundo y'amazi kuko kashe ni umuzingi utwikiriwe na reberi;kandi kubera ko kashe ishobora kuba umupira umwe cyangwa imipira myinshi, irashobora gukorwa mumurambararo munini.Ariko, kashe yacyo ni umwobo wuzuye utwikiriwe na reberi, idakwiriye imiyoboro y'umuvuduko ukabije, ariko ikwiriye gusa imiyoboro iciriritse kandi ntoya.

Kubera ko igikonoshwa cyumupira wo kugenzura umupira gishobora kuba gikozwe mubyuma bitagira umwanda, kandi umwobo wubusa wa kashe urashobora gutwikirwa na plastiki yubuhanga bwa PTFE, urashobora kandi gukoreshwa mumiyoboro hamwe nibitangazamakuru rusange byangiza.

Ubushyuhe bwo gukora bwubu bwoko bwa cheque valve iri hagati ya -101 ~ 150 ℃, umuvuduko wizina ni ≤4.0MPa, naho intera ya diameter iri hagati ya 200 ~ 1200mm.
