Umubumbe w'isi, amarembo y amarembo, ibinyugunyugu, kugenzura, imipira yumupira, nibindi byose nibice byingenzi bigenzura muri sisitemu zitandukanye. Buri valve iratandukanye mumiterere, imiterere ndetse no gukoresha imikorere. Nyamara, umubumbe wa globe na valve by irembo bifite aho bihuriye mumiterere, kandi byombi bifite umurimo wo guca mumiyoboro, inshuti nyinshi rero zidafite aho zihurira na valve zizitiranya byombi. Mubyukuri, niba witegereje neza, itandukaniro riri hagati yisi ya valve ninjoro nini nini.

1 Imiterere

Mugihe umwanya wo kwishyiriraho ari muto, ugomba kwitondera guhitamo. Irembo ry irembo rirashobora gufungwa cyane hamwe nubuso bwa kashe hamwe nigitutu giciriritse, kugirango ugere ku ngaruka zo kutameneka. Iyo gufungura no gufunga,intandaro ya valve hamwe nicyicaro cya kashe hejurubahora bahuza kandi bagasiba hagati yabo, kuburyo hejuru yikimenyetso byoroshye kwambara. Iyo irembo ry'irembo ryegereye gufunga, itandukaniro ryumuvuduko hagati yimbere ninyuma yumuyoboro ni munini cyane, bigatuma ubuso bwa kashe bwambara cyane. Imiterere ya irembo rya valve izagorana kuruta isi ya valve. Uhereye kubireba, munsi ya kalibiri imwe, irembo ry irembo rirenze hejuru yisi, kandi umubumbe wisi ni muremure kuruta irembo. Mubyongeyeho, valve yumuryango nayo igabanijwemo uruti ruzamuka nigiti cyihishe. Umuyoboro w'isi ntufite.

Ihame ry'akazi

Iyo guhagarara guhagarara gufunguye no gufungwa, ni ubwoko bwikigina cyizamuka, ni ukuvuga, mugihe intoki zahinduwe, intoki izunguruka ikazamuka ikagwa hamwe nigiti cya valve. Irembo ry'irembo rihindura intoki kugira ngo igiti cya valve kizamuke kandi kigwe, kandi umwanya wikiganza ubwacyo ntigihinduka. Igipimo cyo gutemba kiratandukanye. Irembo ry'irembo risaba gufungura byuzuye cyangwa gufunga byuzuye, mugihe guhagarara guhagarara ntabwo. Guhagarika valve byagaragaje icyerekezo cyo gusohoka no gusohoka; irembo ry irembo ntirishobora kwinjirira no gusohoka. Icyongeyeho, irembo ry irembo rifite leta ebyiri gusa: gufungura byuzuye cyangwa gufunga byuzuye. Gufungura amarembo no gufunga ni binini kandi igihe cyo gufungura no gufunga ni kirekire. Icyapa cya plaque yimodoka yahagaritswe ni ntoya cyane, kandi plaque ya valve yahagaritswe irashobora guhagarara ahantu runaka mugihe cyo kugendagenda kugenzura. Irembo ry'irembo rishobora gukoreshwa gusa mugukata kandi ntayindi mirimo ifite.

3 Itandukaniro ryimikorere

Guhagarika valve birashobora gukoreshwa mugukata byombikuzimya no gutemba. Kurwanya amazi ya valve ihagarara ni nini cyane, kandi biraruhije gukingura no gufunga, ariko kubera ko isahani ya valve ari ngufi kuva hejuru yikimenyetso, gufungura no gufunga ni bigufi. Kuberako irembo ry irembo rishobora gukingurwa gusa no gufungwa byuzuye, iyo rimaze gukingurwa byuzuye, imiyoboro iringaniye iringaniye mumiyoboro yumubiri wa valve ni 0, bityo valve yumuryango izakoresha imbaraga nyinshi kugirango ifungure kandi ifunge, ariko irembo ni kure yikimenyetso, kandi gufungura no gufunga ni birebire.

4 Kwinjiza no kuyobora icyerekezo

Irembo rya valve rifite ingaruka zimwe mubyerekezo byombi, kandi nta gisabwa icyerekezo cyinjira nisohoka mugihe cyo kwishyiriraho, kandi uburyo bushobora gutemba mubyerekezo byombi. Guhagarika valve bigomba gushyirwaho muburyo bwerekezo cyimyambi kumubiri. Hariho kandi amabwiriza asobanutse kumurongo winjira no gusohoka werekeza guhagarara. valve yigihugu cyanjye "bitatu-muri-imwe" iteganya ko icyerekezo gitemba cya valve ihagarara buri gihe kuva hejuru kugeza hasi.

Guhagarika valve ni bike byinjira kandi bisohoka, kandi bivuye hanze biragaragara ko umuyoboro utari kumurongo umwe utambitse. Irembo rya valve itemba iri kumurongo umwe utambitse. Inkoni ya rugi ya valve nini kuruta iyo guhagarara.

Urebye uburyo bwo kurwanya imigezi, irembo ry irembo rifite irwanya rito iyo rifunguye neza, kandi igenzura rya valve rifite irwanya rinini. Coefficient de coiffure ya valve isanzwe ya 0.08 ~ 0.12, imbaraga zo gufungura no gufunga ni nto, kandi uburyo bushobora gutemba mubyerekezo bibiri. Kurwanya gutembera kwimyanya isanzwe ihagarara ni inshuro 3-5 zububiko. Iyo gufungura no gufunga, gufunga ku gahato birasabwa kugirango ugere kashe. Intanga ya valve yahagaritse valve ihuza ubuso bwo gufunga gusa iyo ifunze burundu, bityo kwambara hejuru yikimenyetso ni bito cyane. Kubera ko imbaraga nyamukuru zitemba ari nini, guhagarika valve ikenera moteri igomba kwitondera ihinduka ryuburyo bwo kugenzura umuriro.

Hariho uburyo bubiri bwo gushiraho valve ihagarara. Imwe ni uko uburyo bushobora kwinjira kuva hepfo ya valve yibanze. Akarusho nuko gupakira bitaba munsi yigitutu mugihe valve ifunze, ishobora kongera igihe cyakazi cyo gupakira, kandi gupakira birashobora gusimburwa mugihe umuyoboro uri imbere ya valve uri mukibazo; ibibi ni uko moteri yo gutwara ya valve ari nini, ikubye inshuro 1 iy'umuvuduko uva hejuru, kandi imbaraga za axial ku giti cya valve nini, kandi uruti rwa valve rworoshye kugorama. Kubwibyo, ubu buryo busanzwe bukwiranye gusa na diameter ntoya yo guhagarara (munsi ya DN50), no guhagarara hejuru ya DN200 koresha uburyo bwo gutembera hagati kuva hejuru. .
