Iremboni umusaruro wa revolution yinganda. Nubwo ibishushanyo mbonera bimwe na bimwe, nk'imibumbe ya globe na plaque, byabayeho kuva kera, indangagaciro z'irembo zifite umwanya wiganje mu nganda mu myaka ibarirwa muri za mirongo, kandi vuba aha ni zo zatanze umugabane munini ku isoko ku mupira w’umupira no mu binyugunyugu. .

Itandukaniro riri hagati ya valve valve na ball ball, plug valve na kinyugunyugu ni uko ikintu cyo gufunga, cyitwa disiki, irembo cyangwa occluder, kizamuka hepfo yikibabi cyangwa uruziga, kiva mumazi cyinjira hejuru ya valve, cyitwa bonnet, no kuzunguruka binyuze muri spindle cyangwa kuzunguruka muburyo bwinshi. Iyi mibande ifunguye mumurongo umwe uzwi kandi nka byinshi bihinduranya cyangwa umurongo ugereranya, bitandukanye na kimwe cya kane cyizenguruka, gifite uruti ruzunguruka dogere 90 kandi ntisanzwe ruzamuka.

Irembo ryamarembo riraboneka mubikoresho byinshi bitandukanye hamwe nu rutonde rwumuvuduko. Zifite ubunini kuva kuri NPS ihuye n'ukuboko kwawe ½ Injira mu gikamyo kinini NPS 144. Irembo ry'irembo rigizwe na casting, kwibagirwa, cyangwa ibice byahimbwe no gusudira, nubwo igishushanyo mbonera cyiganje.

Kimwe mu bintu byifuzwa cyane mumarembo y amarembo nuko ashobora gukingurwa byuzuye hamwe nimbogamizi nke cyangwa guterana mumyobo. Kurwanya urujya n'uruza rutangwa na rugi rufunguye rufunguye hafi ya kimwe nigice cyumuyoboro ufite ubunini bwicyambu. Kubwibyo, amarembo yamarembo aracyafatwa cyane muguhagarika cyangwa kuri / kuzimya porogaramu. Mubisobanuro bimwe na bimwe bya valve, amarembo y amarembo yitwa globe valve.

Irembo ry'irembo muri rusange ntabwo rikwiriye kugenga imigendekere cyangwa gukorera mu cyerekezo icyo aricyo cyose kitari gufungura byuzuye cyangwa byuzuye. Gukoresha igice gifunguye amarembo kugirango uhindurwe cyangwa ugenzure imigendekere bishobora kwangiza plaque ya valve cyangwa impeta yintebe ya valve, kubera ko ahantu hafunguye igice cyimyanya itera imivurungano, hejuru yintebe ya valve izagongana.

Irembo rya valve

Uhereye hanze, amarembo menshi arasa. Ariko, hariho uburyo bwinshi butandukanye bwo gushushanya. Ibyinshi mumarembo agizwe numubiri na bonnet, irimo ikintu cyo gufunga cyitwa disiki cyangwa irembo. Ikintu cyo gufunga cyahujwe nuruti runyura muri bonnet hanyuma amaherezo kuri handwheel cyangwa indi disiki kugirango ikore uruti. Umuvuduko ukikije uruti rwa valve ugenzurwa nugupakira gukusanyirizwa ahapakira cyangwa mucyumba.

Urujya n'uruza rw'irembo rw'irembo ku rubaho rwa valve rugena niba igiti cya valve kizamuka cyangwa cyinjiye mu isahani ya valve mugihe cyo gufungura. Iyi myitwarire isobanura kandi uburyo bubiri bwingenzi / disiki yuburyo bwamarembo: kuzamuka uruti cyangwa urwego rutazamuka (NRS). Igiti kizamuka nuburyo bukunzwe cyane bwo gushushanya / disiki yubushakashatsi ku isoko ryinganda, mugihe uruti rutazamuka rumaze igihe kinini rutoneshwa ninganda zamazi ninganda. Porogaramu zimwe zoherejwe zikoresha amarembo kandi zifite umwanya muto nazo zikoresha uburyo bwa NRS.

Igishushanyo gikunze kugaragara / bonnet kumurongo winganda ni urudodo rwo hanze hamwe ningogo (OS&Y). Igishushanyo cya OS&Y kirakwiriye cyane kubidukikije byangirika kuko insanganyamatsiko ziherereye hanze yikidodo cyamazi. Iratandukanye nibindi bishushanyo muburyo intoki zifatanije nigihuru hejuru yingogo, ntabwo kijyanye nigiti ubwacyo, kugirango intoki ntizamuka mugihe valve ifunguye.

Irembo rya valve isoko

Nubwo mu myaka 50 ishize, impande zombi zizenguruka zifite umwanya munini ku isoko ry’irembo, inganda zimwe na zimwe ziracyashingira cyane kuri zo, harimo n’inganda za peteroli na gaze. Nubwo imipira yumupira imaze gutera imbere mumiyoboro ya gaze karemano, peteroli ya peteroli cyangwa imiyoboro y'amazi iracyari ikibanza cyimyanya iringaniye.

Kubireba ubunini bunini, amarembo y amarembo aracyahitamo nyamukuru kubikorwa byinshi muruganda rutunganya. Gukomera kwishusho nigiciro cyose cya nyirubwite (harimo nubukungu bwo kubungabunga) ningingo zifuzwa ziki gishushanyo gakondo.

Kubijyanye no kubishyira mu bikorwa, gutunganya ibintu byinshi bikoresha ubushyuhe burenze ubushyuhe bwa Teflon bukora neza, nicyo kintu nyamukuru cyicaro cyumupira ureremba. Imikorere yikinyugunyugu ikora cyane hamwe nicyuma gifunze imipira yumupira utangiye gukoreshwa cyane mubikorwa byo gutunganya inganda, nubwo igiciro rusange cya nyirubwite gisanzwe kiri hejuru yicy'irembo.

Inganda z’amazi ziracyiganjemo amarembo yicyuma. Ndetse no mubisabwa byashyinguwe, birahendutse kandi biramba.

Inganda zikoresha ingufu zikoreshaalloy amarembokubisabwa birimo umuvuduko mwinshi cyane nubushyuhe bwo hejuru. Nubwo amashanyarazi mashya Y yo mu bwoko bwa Y hamwe nicyuma cyicaye cyumupira cyagenewe kuburizamo serivisi cyabonetse muruganda rwamashanyarazi, indangagaciro zamarembo ziracyatoneshwa nabashushanya nababikora.
