Itandukaniro hagati yo gucecekesha cheque ya valve na cecekesha igenzura ahanini biterwa nurwego rwo guceceka.Gucecekesha igenzurakuraho gusa urusaku no kugabanya urusaku.Kugenzura buceceIrashobora gukingira no gucecekesha amajwi iyo ikoreshejwe.
Kugenzura bucecezikoreshwa cyane cyane mumiyoboro ya sisitemu yamazi kandi igashyirwa kumasoko ya pompe yamazi. Igizwe numubiri wa valve, disiki ya valve, stem stem, isoko nibindi bice. Gufunga inkoni ni ngufi kandi umuvuduko winyuma ni muto mugihe cyo gufunga. Ikirangantego cya disiki gifata kashe ya reberi yoroshye, kandi kugaruka kwamasoko bituma valve ifunguka kandi igafunga nta ngaruka, bigabanya urusaku ningaruka zinyundo zamazi, bityo byitwa kugenzura icecekesha. Intanga ya valve ifata imiterere yo guterura kandi ni ubwoko bwo guterura igenzura.
Gucecekesha igenzuraByashizweho cyane. Kuburyo bubiri bwo kuyobora valve cores, zirashobora kandi gushyirwaho mu buryo butambitse. Nyamara, kububiko bunini bwa diameter, uburemere-bwa-disiki ya valve ni nini cyane, bizatera kwambara kuruhande rumwe ku kiyobora, kandi mubihe bikomeye bigira ingaruka ku kashe. Kubwibyo, birasabwa gushiraho uhagaritse kumpande nini ya diameter.
Igenzura ryicecekeye nanone ryitwa axial flow check valve, nigikoresho cyingenzi cyashyizwe kumasoko ya pompe cyangwa compressor kugirango wirinde gusubira inyuma. Kuberako imigozi ya axial igenzura valve ifite ibiranga ubushobozi bukomeye bwo gutembera, kwihanganira gutembera guto, uburyo bwiza bwo gutemba, gufunga byizewe kandi nta nyundo y'amazi iyo ifunguye no gufunga. Yashyizwe kumazi wamazi ya pompe yamazi kandi irashobora gufungwa vuba mbere yuko amazi atemba. , kugirango wirinde inyundo y'amazi, amajwi y'inyundo n'ingaruka zangiza kugirango ugere ku gacerere. Kubwibyo, yakoreshejwe cyane mumiyoboro ya peteroli na gaze intera ndende, uruganda rukora ingufu za kirimbuzi amazi meza, compressor na pompe nini mumashanyarazi manini ya etilene, nibindi.
Igizwe ahanini numubiri wa valve, intebe ya valve, disiki ya valve, isoko, kuyobora inkoni, kuyobora amaboko, kuyobora igifuniko nibindi bice. Ubuso bwimbere bwumubiri wa valve, igifuniko kiyobora, disiki ya valve nibindi bice bitambuka bigomba gutondekwa kugirango bihuze imiterere ya hydraulic, kandi bigomba kuzunguruka imbere hanyuma bikerekanwa inyuma kugirango ubone inzira nziza y'amazi meza. Amazi yitwara cyane cyane nka laminari itemba hejuru yayo, hamwe na turbulance nkeya. Umuyoboro w'imbere wumubiri wa valve ni imiterere ya Venturi. Iyo amazi atembera mumiyoboro ya valve, iragenda igabanuka buhoro buhoro, igabanya ibisekuruza byamazi. Gutakaza umuvuduko ni bito, uburyo bwo gutemba burahagaze, nta cavitation, n urusaku ruke.
Urashobora gushyirwaho utambitse kandi uhagaritse. Iyo umurambararo munini ushyizwe mu buryo butambitse, inkoni iyobora igomba gufata uburyo bubiri bwo kuyobora kugirango wirinde kwambara cyane kuruhande rumwe rwamaboko yubuyobozi hamwe ninkoni yo kuyobora iterwa nuburemere bwa disiki ya valve. Ibi bitera kashe ya valve igabanya ingaruka kandi urusaku rwiyongera iyo rufunze.
Itandukaniro hagati ya Gucecekesha kugenzura indangagaciro na cheque ituje:
1. Imiterere ya valve iratandukanye. Imiterere ya icecekesha igenzura valve iroroshye, kandi umuyoboro utemba ugenzura valve ifite imiterere isanzwe. Imiterere ya axial flow cheque valve irarenze gato. Umuyoboro w'imbere wumubiri wa valve nuburyo bwa Venturi hamwe nuyobora imbere. Ubuso bwuzuye butemba. Inzibacyuho yoroheje yumuyoboro utemba igabanya imigezi ya eddy kandi igabanya neza kwihanganira imigezi.
2. Imiterere yibanze ya valve iratandukanye. Igikoresho cyo gucecekesha icyuma gifata reberi yoroheje ifunze neza, kandi intoki zose zuzuyeho reberi, cyangwa intebe ya valve ifunze hamwe nimpeta. Kugenzura imigozi ya Axial irashobora gukoresha ibyuma bifunze kashe hamwe nibishobora gukomera, cyangwa byoroshye kandi bikomeye. Ubuso bwa kashe buraramba kandi bwongerera igihe umurimo.
3. Ibikorwa bikoreshwa mubikorwa biratandukanye. Kugenzura bucece bikoreshwa cyane cyane mumiyoboro isanzwe yubushyuhe nka sisitemu yamazi, hamwe numuvuduko wizina PN10 - PN25 na diameter DN25-DN500. Ibikoresho birimo ibyuma, ibyuma, hamwe nicyuma. Kugenzura imigezi ya Axial ikoreshwa muburyo bwagutse bwo gukoreshwa, kuva gaze gasanzwe ya lisukiya ku bushyuhe buke bwa -161 ° C kugeza ku bushyuhe bwo hejuru. Umuvuduko w'izina PN16-PN250, Abanyamerika basanzwe150-Icyiciro1500. Diameter DN25-DN2000.
