Mugihe umwanya wo kwishyiriraho ari muto, nyamuneka witondere:

Irembo ry irembo rirashobora gufungwa cyane hamwe nubuso bwa kashe hamwe nigitutu giciriritse, kugirango ugere ku ngaruka zo kutameneka.Iyo gufungura no gufunga, intoki ya valve hamwe nicyicaro cyikimenyetso cyo gufunga buri gihe bihura kandi bigasunikana, kuburyo gufunga byoroshye kwambara.Iyo irembo ry irembo riri hafi yo gufunga, itandukaniro ryumuvuduko hagati yimbere ninyuma yumuyoboro ni munini, bigatuma ubuso bwa kashe bwambara cyane.

Imiterere ya rugi ya valve izagorana kuruta iy'isi yose.Urebye uko bigaragara, irembo ry irembo rirerire kuruta umubumbe wisi kandi umubumbe wisi ni muremure kuruta irembo ryumuryango munsi ya diameter.Mubyongeyeho, indangagaciro z'irembo zigabanyijemo inkoni zifunguye hamwe n'inkoni zijimye.Gufunga valve ntabwo.

Ese isi ya valve na valve ya valve irashobora kuvangwa?

ihame ry'akazi

Iyo umubumbe wa globe ufunguye kandi ugafungwa, ni ubwoko bwikigina cyizamuka, nukuvuga, mugihe intoki zahinduwe, intoki izunguruka ikazamura hamwe hamwe nigiti cya valve.Irembo ry'irembo ni ukuzenguruka intoki kugirango igiti cya valve kizamuke hejuru no hepfo, kandi umwanya wikiganza ubwacyo ntigihinduka.

Ibiciro bitemba biratandukanye, amarembo yumuryango bisaba gufungura byuzuye cyangwa gufunga byuzuye, kandi isi yose ntabwo.Umubumbe w'isi werekanye icyerekezo cyo gusohoka no gusohoka, mugihe amarembo yo mumarembo adafite ibisabwa kugirango yinjire kandi asohoke.

Mubyongeyeho, valve yumuryango ifite leta ebyiri gusa: gufungura byuzuye cyangwa gufunga byuzuye, gufungura amarembo no gufunga ni binini, kandi igihe cyo gufungura no gufunga ni kirekire.Urujya n'uruza rw'ibibaho bya plaque ya valve ni ntoya cyane, kandi plaque ya plaque ya valve yisi irashobora guhagarara ahantu runaka mugihe cyo kugendana kugenzura.Irembo ry'irembo rishobora gukoreshwa gusa muguhagarika kandi ntayindi mirimo ifite.

Itandukaniro ryimikorere

Umuyoboro w'isi urashobora gukoreshwa muburyo bwo guca no gutemba.Kurwanya amazi ya valve yisi ni nini cyane, kandi biraruhije gukingura no gufunga, ariko kubera ko intera iri hagati yicyapa cya valve nubuso bwa kashe ari ngufi, gufungura no gufunga ni bigufi.

Kuberako irembo ryamarembo rishobora gukingurwa gusa no gufungwa byuzuye, iyo rifunguye byuzuye, imiyoboro iringaniye iringaniye mumiyoboro yumubiri wa valve ni 0, bityo gufungura no gufunga amarembo bizakiza cyane umurimo, ariko irembo riri kure yikimenyetso, kandi gufungura no gufunga ni birebire..

kwishyiriraho no gutemba

Uwitekairemboifite ingaruka zimwe mubyerekezo byombi.Nta gisabwa cyerekezo cyinjira no gusohoka, kandi uburyo bushobora gutemba mubyerekezo byombi.Umubumbe wisi ugomba gushyirwaho muburyo bukurikije icyerekezo cyerekanwe numwambi kumubiri wa valve.Hariho kandi amabwiriza asobanutse kubyerekezo byinjira no gusohoka kwisi ya valve.“Uburyo butatu bwa chimique” yimibande mugihugu cyanjye buteganya ko icyerekezo gitemba cyumubumbe wisi kizaba kuva hejuru kugeza hasi.

Umuyoboro w'isi uri hasi kandi muremure, kandi biragaragara hanze ko umuyoboro utari kumurongo utambitse w'icyiciro kimwe.Irembo rya valve itemba iri kumurongo utambitse.Inkoni ya rugi nini nini kuruta iy'isi yose.

Duhereye ku buryo bwo guhangana n’imigezi, irwanya umuvuduko w irembo rya rugi ni rito iyo rifunguye byuzuye, kandi irwanya umuvuduko wimitwaro igenzura ni nini.Coefficente yo kurwanya imigezi ya valve isanzwe ni 0.08 ~ 0.12, imbaraga zo gufungura no gufunga ni nto, kandi uburyo bushobora gutemba mubyerekezo bibiri.Kurwanya umuvuduko wibisanzwe byisi byikubye inshuro 3-5 ibyo mumarembo.Iyo gufungura no gufunga, bigomba guhatirwa gufunga kugirango ugere kashe.Intanga ya valve yisi yose ihuza gusa na kashe hejuru iyo ifunze burundu, kubwibyo kwambara hejuru yikimenyetso ni bito cyane.Bitewe no gutembera kwinshi kwingufu nyamukuru, valve yisi ikenera moteri igomba kwitondera uburyo bwo kugenzura umuriro.Guhindura.

Hariho uburyo bubiri bwo gushiraho isi ya valve.Imwe ni uko uburyo bushobora kwinjira kuva hepfo ya valve yibanze.Akarusho nuko gupakira bidafite igitutu mugihe valve ifunze, ishobora kongera igihe cyakazi cyo gupakira kandi irashobora kwihanganira umuvuduko mumuyoboro mbere ya valve.Mubihe, gusimbuza ibipapuro bikorwa;ibibi ni uko moteri yo gutwara ya valve ari nini, ikubye inshuro 1 iy'amazi yo hejuru, imbaraga za axial ku giti cya valve nini, kandi uruti rwa valve rworoshye kugorama.

Kubwibyo, ubu buryo busanzwe bukwiranye gusa na diyimetero ntoya ya globe yisi (munsi ya DN50), naho umubumbe wisi uri hejuru ya DN200 ukoresha uburyo uburyo butembera buva hejuru..

Ikidodo

Ubuso bwa kashe ya globe yisi ni uruhande ruto rwa trapezoidal rwibanze rwa valve (byumwihariko biterwa nuburyo imiterere ya valve).Iyo intoki ya valve imaze kugwa, ihwanye no gufunga valve (niba itandukaniro ryumuvuduko ari rinini, birumvikana ko ridafunze cyane, ariko ingaruka zo kurwanya ingaruka ntabwo ari mbi).Irembo ry'irembo rifunze ku ruhande rw'irembo ry'ibanze.
