Itandukaniro riri hagati yisi na valve, ihitamo gute?

Reka tumenye itandukaniro riri hagati ya valve yisi na airembo.

01

Imiterere

Mugihe umwanya wo kwishyiriraho ari muto, witondere guhitamo:

UwitekairemboIrashobora kwishingikiriza kumuvuduko wo hagati kugirango ufunge neza hejuru yikidodo, kugirango ugere ku ngaruka zo kumeneka. Mugihe cyo gufungura no gufunga, intoki ya valve hamwe nubuso bwa kashe yintebe ya valve ihora ihurira hamwe no gukubitana, bityo hejuru yikimenyetso biroroshye kwambara, kandi iyoiremboni hafi yo gufunga, itandukaniro ryumuvuduko hagati yimbere ninyuma yumuyoboro ni munini cyane, bigatuma ubuso bwa kashe bwambara cyane.

Imiterere yairemboBizaba bigoye kuruta isi ya valve, uhereye kumiterere igaragara, mugihe cya kalibiri imwe, irembo ry irembo rirenze hejuru yisi, kandi umubumbe wisi ni muremure kurutairembo. Byongeyeho ,.iremboigabanijwemo inkoni yaka ninkoni yijimye. Kuzimya indangagaciro ntabwo.

Uburyo ikora

Iyo umubumbe wa globe ufunguye kandi ugafunga, ni uruti ruzamuka, ni ukuvuga, mugihe intoki zizunguruka, intoki zizunguruka kandi zizamura hamwe nigiti. Uwitekairemboni ukuzenguruka intoki kugirango gukora igiti cya valve gikora ingendo, kandi umwanya wikiganza ubwacyo ntigihinduka.

Ibiciro bitemba biratandukanye, hamweamarembobisaba gufunguka byuzuye cyangwa gufunga byuzuye, mugihe isi ya valve ntabwo. Umubumbe wa globe ufite icyerekezo cyerekanwe kandi gisohoka, nairemboidafite icyerekezo cyo gusohoka no gusohoka.

Byongeyeho ,.iremboifite leta ebyiri gusa: gufungura byuzuye cyangwa gufunga byuzuye, kandi inkoni yo gufungura no gufunga icyapa cy'irembo ni nini cyane, kandi igihe cyo gufungura no gufunga ni kirekire. Kwimuka kwa plaque ya plaque ya valve yisi ni ntoya cyane, kandi plaque ya valve ya globe yisi irashobora guhagarara ahantu runaka kugirango ihindurwe neza. Uwitekairemboirashobora 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.

Kubera koiremboBirashobora gukingurwa gusa no gufungwa, iyo byafunguwe byuzuye, imiyoboro yo hagati irwanya imiyoboro yumubiri wa valve ni 0, bityo gufungura no gufunga kwairemboBizakoreshwa cyane, ariko isahani y irembo iri kure yikimenyetso, kandi igihe cyo gufungura no gufunga ni kirekire.

Kwinjiza no gutembera icyerekezo

Ingaruka zairemboicyerekezo gitemba mubyerekezo byombi ni kimwe, ntakintu gisabwa cyinjira no gusohoka cyerekezo cyo kwishyiriraho, kandi uburyo bushobora gutemba mubyerekezo byombi. Umubumbe wa globe ugomba gushyirwaho muburyo bukurikije icyerekezo cyaranzwe numwambi wumubiri wa valve, kandi hariho ingingo isobanutse kubyerekezo byinjira no gusohoka kwisi ya globe, kandi icyerekezo gitemba cyumubumbe wisi ni byemejwe kuva hejuru kugeza hasi ukurikije "impinduka eshatu" za valve y'Ubushinwa.

Gufunga-valve biri hasi kandi hejuru, kandi uhereye hanze hari umuyoboro usobanutse utari kurwego rwicyiciro kimwe. Uwitekairemboinzira itemba iri kumurongo utambitse. Inkoni yairemboni nini kuruta iy'isi ya valve.

Urebye uburyo bwo kurwanya imigezi, iyo ifunguye byuzuye, irwanya umuvuduko w irembo ni rito, kandi irwanya imizigo ihagarara valve nini. Coefficient de coiffure isanzweiremboni nka 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 ibyoamarembo.Gufungura no gufunga bigomba guhatirwa gufunga kugirango ugere ku kashe, isuka ya valve yisi irafunga burundu iyo ihuye nubuso bwa kashe, bityo kwambara hejuru yikidodo ni bito cyane, kubera umuvuduko munini wingufu nyamukuru kuri ongeramo actuator ya globe valve igomba kwitondera uburyo bwo kugenzura torque.

Hariho uburyo bubiri bwo kwinjizamo ububiko bwisi, bumwe nuko uburyo bushobora kwinjira munsi yigitereko, akarusho nuko gupakira bidashyizweho igitutu mugihe valve ifunze, ishobora kongera igihe cyumurimo wo gupakira, kandi irashobora gusimbuza gupakira iyo umuyoboro uri imbere ya valve uri mukibazo; Ikibi ni uko moteri yo gutwara ya valve ari nini, ikubye inshuro 1 iy'amazi yo hejuru, imbaraga za axial z'uruti rwa valve nini, kandi uruti rwa valve rworoshye kugorama.

Kubwibyo, ubu buryo busanzwe bukwiranye gusa na diametre ntoya yisi (DN50 cyangwa munsi yayo), kandi umubumbe wisi uri hejuru ya DN200 ukoresha uburyo butemba buva hejuru. .

Ikidodo

Ubuso bwa kashe ya globe yisi ni uruhande ruto rwa trapezoidal rwibanze rwa valve (reba cyane cyane imiterere yimiterere ya valve), iyo intoki ya valve imaze kugwa, ihwanye no gufunga valve (niba itandukaniro ryumuvuduko ari rinini, byumvikane, gufunga ntabwo bikomeye, ariko kugenzura ingaruka ntabwo ari bibi), theirembogifunzwe kuruhande rwurupapuro rwibanze rwa valve, ingaruka yo gufunga ntabwo ari nziza nkumubumbe wisi, kandi intanga ya valve ntizagwa nka valve yisi ihwanye no gufunga valve.
