Regulating valvenhoroondo yebudiriro inodzora kugadzwa kwevharuvhu sumo pfupi
1. Kuvandudzwa kwekugadzirisa mavharuvhu kwakabatana zvakanyanya nekuvandudzwa kwemaitiro ekugadzira maindasitiri.
Makarekare, kuti vagadzirise kuyerera kwemvura munzizi kana munzizi, vanhu vaishandisa matombo makuru kana hunde dzemiti kumisa kuyerera kwemvura kana kuti kuchinja kwaienda mvura.
Magariro eEgypt neGreek akagadzira akati wandei ekare mavharuvhu, anoshandiswa kudiridza zvirimwa, pakati pezvimwe zvinhu.
Zvakadaro, zvinobvumwa kuti maRoma ekare vakagadzira hurongwa hwemvura hwakaoma hwekudiridza zvirimwa, nemavharuvhu eplug nemaplunger uye kushandisa mavharuvhu ekudzivirira kuyerera kwemvura kune reverse.
Munguva yeRenaissance, maartist uye vagadziri. LeonardodaVinc akagadzira mavharuvhu emigero, mapurojekiti ekudiridza uye mamwe mahombe hydraulic masisitimu, uye mazhinji emagadzirirwo ake ehunyanzvi achiripo nhasi.
Nhoroondo yemazuva ano yeindasitiri yevharuvhu yakaenda pamwe chete neindasitiri. Nekufambira mberi kweindastiri, ThomasNewcomen akagadzira injini yekugadzira indasitiri nepamberi pedhesiki muna 1705, ichida kutonga kwekushanda kweinjini. JamesWatt akagadzira mutongi wekugadzirisa kumhanya nedhesiki rekumberi. Vanhu vakawanda vanoteerera kudzora kuyerera kwemvura.
Mutongi wepakutanga aiva pombi regulator yakagadzirwa naWilliamFisher muna 1880. Yaiva mutongi anozvimiririra ane sando inorema. Apo kudzvinyirirwa kuseri kwevhavha kwakawedzera, kuvhurwa kwemutongi kwakaderedzwa pasi pechiito chenyundo inorema, kuitira kuti iwane simba rekutonga rekugadzikana kwakagadzikana.

Eccentric rotary valve ine chisimbiso chakanaka, yakakura kuyerera simba, inogona kushandiswa mukumanikidza kwakakura kusiyanisa zviitiko.
Kubva pakutanga kwe80's, yakasiyana-siyana yakanaka diki yekudzora valve yakazvarwa, iyo inoita kuti uremu uye kukwirira kweiyo inodzora kudonha kwevhavha uye kuyerera kwesimba kuvandudza.
Kubva kutanga kwema1990, nekushandiswa kwakakura kwemichina yekudzora komputa, zvinodiwa zvemavharuvhu ekudzora akangwara zviri kuwedzera uye zvakanyanya, uye zvakazvarwa zvakasiyana-siyana zvine hungwaru zvemagetsi mavharuvhu chinzvimbo uye bhazi remumunda rinotonga mavharuvhu ane akangwara vharafu chinzvimbo.
Pakutanga kwezana remakore re2l, fieldbus regulating valve yakashandiswa, nekuderera kwekufamba kwebasa rekutonga, zvinodiwa zvekugadzirisa valve zvinowedzera uye zvakanyanya.
Iko kuvandudza kwekugadzirisa valve uye maindasitiri maitiro ekugadzirisa kunoitwa synchronously.
Kuti uvandudze hutongi hwehutongi hwehurongwa hwekutonga, zvinodiwa zvepamusoro zvinoiswa mberi kune chimwe nechimwe chikamu chekutonga.
Semuenzaniso, zvinhu zvekuona uye zvinotumira zvinoda kutariswa kwepamusoro uye kurongeka kwekufambisa, kukurumidza kupindura uye kugadzikana kwedata kwepamusoro; Iyo regulator uye mamwe ma actuators anoda diki nzvimbo yakafa uye kukweshana, zvirinani kudzokorora uye ipfupi nguva yekupindura, uye inogona kupa muripo weiyo isiri-mutsara yekuyerera maitiro echinhu.
Panguva imwecheteyo, nekuda kwehukuru-hukuru uye hwakanakisa kugadzirwa kwemaindasitiri, iyo regulator uye zvichingodaro zvakare inoisa pamberi pepamusoro zvinodiwa.
Pfungwa huru dzekugadzirisa kugadzika kwevhavha dzinounzwa muchidimbu
Ndedzipi nzira dzakakodzera dzekuisa dzekugadzirisa mavharuvhu ekuisa mapoinzi, ayo anogona kuvandudza kushanda kwevhavha uye kuderedza kupfeka kwevhavha? Izvi zvinotevera kusuma pfungwa huru dzekugadzirisa kugadzika kwevharuvhu yereferensi yako. 1) Nzvimbo yekuisa, kureba, inlet uye nzira yekubuda nayo inofanirwa kusangana nezvinodiwa zvekugadzira, uye kubatana kunofanirwa kuve kwakasimba uye kwakasimba. 2) Mubato wemarudzi ese emavharuvhu emaoko akaiswa papombi yekupisa yekupisa haifanirwe kudzika pasi. 3) Ivhavha inofanira kuongororwa isati yaiswa. Zita revhavhavha rinofanira kuenderana nezera remazuva ano "Universal Valve Mark" GB 12220. Nokuda kwevhavha iyo kushanda kwayo kwakakura kudarika 1.0MPa uye inoita basa rekucheka pane pombi huru, simba uye muedzo wekushanda wakaoma unofanira kutakurwa. kunze kusati kwaiswa, uye valve inokwanisa inogona kushandiswa. Muedzo wesimba, kudzvanywa kwebvunzo ndeye 1.5 nguva yekumanikidza kwezita, nguva yacho haisi pasi pe5min, goko revharuvhu, kurongedza kunofanirwa kuve kwakakodzera pasina kuvuza. Tightness bvunzo, bvunzo kudzvanywa ndeye 1.1 nguva dzezita rekumanikidza; Kudzvanywa kweyedzo panguva yekuyedzwa kunofanirwa kusangana nezvinodiwa zveGB 50243 yakajairwa, kune disc yekuisa chisimbiso pamusoro hapana kuvuza sekunokodzera.
