Reka tuvuge itandukaniro riri hagati ya valve y'umubumbe n'iy'umubumbevalve y'irembo.
01
Imiterere
Iyo umwanya wo gushyiramo ari muto, witondere guhitamo:
Itsindavalve y'iremboishobora kwishingikiriza ku gitutu kiri hagati kugira ngo ifunge neza ubuso bwo gufunga, kugira ngo itagira ingaruka zo kuva. Mu gihe cyo gufungura no gufunga, igice cy'imbere cya valve n'igice cyo gufunga cy'intebe ya valve bihora bihura kandi bigaterana, bityo ubuso bwo gufunga bworoshye kwambara, kandi iyovalve y'iremboiri hafi gufunga, itandukaniro ry'umuvuduko hagati y'imbere n'inyuma by'umuyoboro ni rinini cyane, ibyo bigatuma ubuso bwo gufunga burushaho kwangirika cyane.
Imiterere y'ikigovalve y'irembobizaba bigoye kurusha valve y'umubumbe, ukurikije uko bigaragara, mu gihe cy'ubunini bumwe, valve y'irembo iruta valve y'umubumbe, naho valve y'umubumbe ikaba ndende kurusha valve y'umubumbe.valve y'iremboByongeye kandi,valve y'iremboigabanyijemo inkoni irabagirana n'icyuma cyijimye. Valve zifunga ntizikora.
Uko bikora
Iyo valve y'isi yose ifunguwe kandi igafungwa, iba ari uruti ruzamuka, ni ukuvuga ko iyo urutoki ruzungurutse, urutoki ruzunguruka kandi rukazamuka hamwe n'urutoki.valve y'iremboni ukuzunguruka uruziga rw'amaboko kugira ngo uruziga rw'amaboko rukore ingendo zo guterura, kandi aho uruziga rw'amaboko ubwarwo ruherereye ntihahinduke.
Igipimo cy'amazi agenda gitandukana, bitewe n'ukovalve zo mu irembobisaba gufungura neza cyangwa gufunga neza, mu gihe valve z'isi zidafunze neza. Valve y'isi ifite icyerekezo cyihariye cyo kwinjira n'aho isohoka, kandivalve y'irembonta byangombwa by'icyinjiriro n'icyerekezo cy'aho bisohokera bifite.
Byongeye kandi,valve y'iremboifite imiterere ibiri gusa: ifunguye cyangwa ifunze neza, kandi umurongo wo gufungura no gufunga icyuma cyo ku irembo ni munini cyane, kandi igihe cyo gufungura no gufunga ni kirekire. Umurongo wo kugenda w'icyuma cyo ku mpande ni muto cyane, kandi icyuma cyo ku mpande gishobora guhagarara ahantu runaka mu rugendo kugira ngo gihindure umurongo.valve y'iremboishobora gukoreshwa gusa mu gukata kandi nta yindi mirimo ifite.
Itandukaniro mu mikorere
Valve y'umubumbe ishobora gukoreshwa haba mu kugenzura uburyo ihagarara cyangwa itembera. Ubudahangarwa bw'amazi ya valve y'umubumbe ni bunini, kandi biragoye kuyifungura no kuyifunga, ariko kubera ko intera iri hagati y'ikibaho cy'umubumbe n'ubuso bwo gufunga ari ngufi, inzira yo gufungura no gufunga ni ngufi.
Kubera kovalve y'iremboishobora gufungurwa no gufungwa byuzuye gusa, iyo ifunguwe byuzuye, ubushobozi bwo kwirinda amazi anyura mu muyoboro w'umubiri wa valve buba hafi 0, bityo gufungura no gufunga kwavalve y'irembobizagabanya cyane abakozi, ariko icyapa cy'irembo kiri kure y'ubuso bwo gufunga, kandi igihe cyo gufungura no gufunga ni kirekire.

Gushyiraho n'icyerekezo cy'amazi
Ingaruka zavalve y'iremboIcyerekezo cy'amazi mu byerekezo byombi ni kimwe, nta gisabwa ku cyerekezo cy'aho amazi yinjira n'aho asohokera gishyirwaho, kandi icyo cyuma gishobora gutembera mu byerekezo byombi. Valve y'umubumbe igomba gushyirwaho hakurikijwe icyerekezo cyashyizweho n'umwambi w'umubiri wa valve, kandi hari ingingo isobanutse neza ku cyerekezo cy'aho amazi yinjira n'aho asohokera, kandi icyerekezo cy'amazi ya valve y'umubumbe gifatwa kuva hejuru kugeza hasi hakurikijwe "impinduka eshatu" za valve yo mu Bushinwa.
Valve yo kuzimya iri hasi cyane imbere no hanze hejuru, kandi inyuma hari umuyoboro usobanutse utari ku rwego rumwe.valve y'iremboinzira y'amazi iri ku murongo utambitse. Inzira y'amazivalve y'iremboni nini kurusha iy'umugozi w'isi.
Urebye uburyo amazi atemba, iyo ifunguye neza, uburyo amazi atemba bwa valve y'irembo buba buto, kandi uburyo amazi atemba bwa valve ihagarika imizigo buba bunini. Igipimo cyo kwirinda amazi atemba cya gisanzwevalve y'iremboni hafi 0.08 ~ 0.12, imbaraga zo gufungura no gufunga ni nto, kandi igikoresho gishobora gutembera mu byerekezo bibiri. Ubudahangarwa bw'amazi ya valve zisanzwe zo ku isi ni inshuro 3-5 z'umuvudukovalve z'irembo.Gufungura no gufunga bigomba gufungwa kugira ngo bishyirwe mu buryo bufunze, igice cy'umugozi w'umubumbe gifunga burundu iyo kigeze ku buso bwo gufunga, bityo ubusaza bw'umugozi bugahita buba buke cyane, bitewe n'umuvuduko munini w'imbaraga nyamukuru zo kongeramo umuyoboro w'umubumbe w'umubumbe ugomba kwitondera uburyo bwo kugenzura torque.
Hari uburyo bubiri bwo gushyiraho valve y’isi yose, bumwe ni uko icyuma gishobora kwinjira munsi y’umuyoboro, inyungu ni uko gupakira bidashyirwamo umuvuduko iyo valve ifunze, ibyo bikaba bishobora kongera igihe cyo gupakira, kandi bigasimbuza gupakira iyo umuyoboro uri imbere ya valve uri munsi y’umuvuduko; Ingorane ni uko imbaraga zitwara valve ari nini, zikubye inshuro imwe ugereranyije n’umuvuduko wo hejuru, imbaraga z’umurongo w’inyuma w’umuyoboro w’inyuma ari nini, kandi inkingi y’inyuma y’umuyoboro w’inyuma yo hasi ikaba ari nini, kandi inkingi y’inyuma yo hasi yoroshye kuyigonda.
Bityo rero, ubu buryo muri rusange bukwiriye gusa ku mashini ntoya zo mu bwoko bwa globe (DN50 cyangwa munsi yayo), kandi mashini zo mu bwoko bwa globe ziri hejuru ya DN200 zikoresha icyuma gisohoka kivuye hejuru. (Imashini zo mu bwoko bwa globe zikoresha icyuma gisohoka hejuru muri rusange zikoresha icyuma gisohoka hejuru.) Imbogamizi z'uburyo bwo kwinjira mu buryo bwa media buturutse hejuru ni ikinyuranyo cy'uburyo bwo kwinjira bwo hasi.

Gufunga
Ubuso bwo gufunga bwa valve y'isi ni uruhande ruto rwa trapezoidal rw'umutima wa valve (reba cyane cyane imiterere y'umutima wa valve), iyo umutima wa valve uguye, bingana no gufunga valve (niba itandukaniro ry'umuvuduko ari rinini, birumvikana ko gufunga bidakomeye, ariko ingaruka zo kugenzura si mbi),valve y'iremboifunze ku ruhande rw'ikibaho cy'inyuma cya valve, ingaruka zo gufunga ntabwo ari nziza nk'iya valve y'isi, kandi valve y'isi ntizagwa nk'iya valve y'isi ingana n'ifunga rya valve.
