Vali z'isi, valves z'irembo, valves z'ibinyugunyugu, valves zo kugenzura, valves z'umupira, nibindi byose ni ibintu by'ingenzi mu kugenzura mu buryo butandukanye bw'imiyoboro. Buri valve iratandukanye mu miterere, imiterere ndetse no mu mikoreshereze yayo. Ariko, valve y'isi n'iy'irembo bifite aho bisa mu miterere, kandi byombi bifite akazi ko gukata mu muyoboro, bityo inshuti nyinshi zidafite aho zihuriye na valves zizabivanga. Mu by'ukuri, iyo witegereje neza, itandukaniro riri hagati ya valve y'isi n'iy'irembo ni rinini cyane.

1 Inyubako

Iyo umwanya wo gushyiramo ari muto, ugomba kwitondera guhitamo. Valve y'irembo ishobora gufungwa neza hamwe n'ubuso bufunga hakoreshejwe igitutu kiri hagati, kugira ngo hatazagira ingaruka zo kuva. Mu gufungura no gufunga,igice cy'imbere cya valve n'ubuso bwo gufunga icyicaro cya valveBihora bihura kandi bigaterana, bityo ubuso bwo gufunga buroroha kwambara. Iyo valve y'irembo iri hafi gufunga, itandukaniro ry'umuvuduko hagati y'imbere n'inyuma by'umuyoboro ni rinini cyane, bituma ubuso bwo gufunga burushaho kwangirika. Imiterere ya valve y'irembo izaba igoye kurusha valve y'isi. Ukurikije uko bigaragara, munsi y'ubunini bumwe, valve y'irembo iba iri hejuru kurusha valve y'isi, kandi valve y'isi ni ndende kurusha valve y'irembo. Byongeye kandi, valve y'irembo nayo igabanyijemo uruti ruzamuka n'uruti rwihishe. Valve y'isi ntabwo ifite.

2 Ihame ry'imikorere

Iyo valve yo guhagarara ifunguwe kandi igafungwa, iba ari ubwoko bw'umugozi w'ingunguru uzamuka, ni ukuvuga ko iyo icyuma gifunguye, icyuma gifunguye kizunguruka kikazamuka kikamanuka hamwe n'umugozi w'ingunguru. Valve y'irembo izunguruka umugozi kugira ngo icyuma gifunguye kikazamuka kikamanuka, kandi aho icyuma gifunguye ubwacyo kiguma gihinduka. Umuvuduko w'amazi uratandukanye. Valve y'irembo isaba gufungura neza cyangwa gufunga neza, mu gihe valve yo guhagarara idakora. Valve yo guhagarara ifite icyerekezo cy'injira n'isohoka cyagenwe; valve y'irembo nta byangombwa by'injira n'isohoka bifite. Byongeye kandi, valve y'irembo ifite imiterere ibiri gusa: gufungura neza cyangwa gufunga neza. Uburyo bwo gufungura no gufunga irembo ni bunini kandi igihe cyo gufungura no gufunga ni kirekire. Uburyo bwo kugenda kwa valve ya valve yo guhagarara ni buto cyane, kandi icyuma gifunguye cya valve yo guhagarara gishobora guhagarara ahantu runaka mu gihe cyo kugenda kugira ngo hagenzurwe uburyo amazi anyuramo. Valve y'irembo ishobora gukoreshwa gusa mu gukata kandi nta yindi mirimo ifite.

3 Itandukaniro mu mikorere

Valve yo guhagarara ishobora gukoreshwa mu gukata byombiKugenzura amazi ava mu gice cy’amazi no mu gice cy’amazi. Ubudahangarwa bw’amazi bwa valve yo guhagarika ni bunini, kandi biragoye gufungura no gufunga, ariko kubera ko icyuma cya valve ari gito uvuye ku gice cyo gufunga, uburyo bwo gufungura no gufunga ni bugufi. Kubera ko valve y’irembo ishobora gufungurwa neza no gufungwa neza gusa, iyo ifunguwe neza, ubudahangarwa bw’amazi hagati mu gice cy’umubiri wa valve buba hafi 0, bityo valve y’irembo izagabanya cyane imbaraga zo gufungura no gufunga, ariko irembo riri kure cyane y’igice cyo gufunga, kandi igihe cyo gufungura no gufunga ni kirekire.

4 Gushyiraho no kwerekeza aho amazi anyura

Valve y'irembo ifite ingaruka zimwe mu byerekezo byombi, kandi nta gisabwa ku cyerekezo cy'aho yinjira n'aho asohokera mu gihe cyo kuyishyiraho, kandi icyo cyuma gishobora gutembera mu byerekezo byombi. Valve yo guhagarara igomba gushyirwa neza mu cyerekezo cy'umwambi ku gice cy'imashini. Hariho kandi amabwiriza asobanutse ku cyerekezo cy'aho yinjira n'aho asohokera cya valve yo guhagarara. Valve yo mu gihugu cyanjye "itatu-muri-imwe" ivuga ko icyerekezo cy'aho valve yo guhagarara gihora gituruka hejuru kugeza hasi.

Valve yo guhagarara ifite aho yinjira hato kandi ifite aho isohoka hanini, kandi urebye inyuma biragaragara ko umuyoboro utari ku murongo umwe utambitse. Umuyoboro w'inzira ya valve yo guhagarara uri ku murongo umwe utambitse. Inzira ya valve yo guhagarara ni nini kuruta iya valve yo guhagarara.

Ukurikije uburyo amazi anyura, valve y'irembo ifite ubushobozi buke bwo guhangana n'amazi iyo ifunguye neza, kandi valve yo kugenzura ifite ubushobozi buke bwo guhangana n'amazi. Igipimo cyo guhangana n'amazi cya valve isanzwe y'irembo ni hafi 0.08 ~ 0.12, imbaraga zo gufungura no gufunga ni nto, kandi igikoresho gishobora gutembera mu byerekezo bibiri. Ubushobozi bwo guhangana n'amazi bwa valve isanzwe yo guhagarika ni inshuro 3-5 z'ingufu z'irembo. Iyo ufungura kandi ufunga, gufunga ku ngufu birakenewe kugira ngo habeho gufunga. Ipfundo ry'ingufu rya valve yo guhagarika rikorana n'ipfundo gusa iyo rifunze burundu, bityo gufunga ku buso bwo guhagarika ni gato cyane. Kubera ko imbaraga nyamukuru yo kugenda ari nini, valve yo guhagarika ikeneye actuator igomba kwitondera ihinduka ry'uburyo bwo kugenzura torque.

Hari uburyo bubiri bwo gushyiraho valve yo guhagarika. Ubwa mbere ni uko icyuma gishobora kwinjira mu gice cyo hasi cy'imbere cya valve. Akamaro ni uko gupakira bitaba biri munsi y'umuvuduko iyo valve ifunze, ibyo bikaba bishobora kongera igihe cyo gupakira, kandi gupakira bishobora gusimburwa iyo umuyoboro uri imbere ya valve uri munsi y'umuvuduko; ikibi ni uko imbaraga zitwara valve ari nini, zikubye inshuro imwe ugereranyije n'umuvuduko uva hejuru, kandi imbaraga z'umurongo ku gice cya valve ni nini, kandi igice cya valve cyoroshye kugonda. Kubwibyo, ubu buryo muri rusange bukwiriye gusa valve nto zo guhagarika (munsi ya DN50), kandi valve zo guhagarika ziri hejuru ya DN200 zikoresha uburyo bwo kwinjira mu gice cyo hejuru. (Valves zo guhagarika amashanyarazi muri rusange zikoresha uburyo bwo kwinjira mu gice cyo hejuru.) Ingorane z'uburyo bwo kwinjira mu gice cyo hejuru ni ikinyuranyo cy'uburyo bwo kwinjira mu gice cyo hejuru.
