Somuenzaniso, funga nezvetangi hombe rine chivharo. Mvura inopinda mutangi yobuda pamusoro wecylinder. Musoro wecylinder unoshanda sechikamu chekuvhara chevhavha. Kana ruoko ruchikwira kumusoro wecylinder, yakaenzana nemutemo wekushanda wevhavha yekumira. Kana iwe ukafambisa musoro wecylinder kumativi ose, unoshanda nenzira imwechete sevhavha yekumisa.

Shandisa chigadzirwa chinotevera:
Vhura bhaa rutsigiro furemu mhando
Screw yakabatana single flow valve; Gasi rinodzvinyirira rinozvisimbisa rimwechete rinoyerera valve
Chimwe chidimbu chepamusoro chekuisa chisimbiso chigaro
A:
Zvikamu zvekuvhura nekuvhara zvevharuvhu yepasi ndeye cylindrical disc, uye iyo protruder surface is planar kana spherical. Ivhavha disc inofamba zvakafanana pamwe chete neakisi yemvura mumutsara wakatwasuka. Mafambiro echitsigiro chevhavhavha, kune magetsi ekusundira tsvimbo yemhando (valve stem adjustment, spindle haina kugadzirisa), uye kugadzirisa rotary rod rudzi (spindle uye valve stem rotation kusimudza, bhoti yakavakwa pairi ndiro). Iyo globe valve ndeyekuvhura nekuvhara chete, yakagadzirirwa inogona kugadziriswa uye throttle valve.
Kana iyo globe valve yakazarurwa, kureba kwakaenzana kwe disc kuvhura ndeye 25% ~ 30% yekunze dhayamita, kuyerera kwese kwasvika kune yakakura kwazvo, zvichiratidza kuti vheji yave yakawanda kupfuura nzvimbo yakazaruka. Nokudaro, nzvimbo yakazara yakazaruka yevhavha yepasi inofanira kugadziriswa ne disc stroke.
Mazano evharuvhu: Dzidzisa iwe kuona mhando yevharuvhu yevharuvhu uye yakajairika vharuvhu rudzi rwevharuvha yekuvharisa uye yekuvharisa kwayo chisimbiso nhanho ndiyo mikuru mikuru yekuona nhanho yekukosha kweindex yevharuvhu. Valve haina kunaka kana yakaipa, yakasarudzika yekushanda mamiriro application valve inogona kushandiswa kwenguva yakareba inogona zvakare kushandiswa kwenguva pfupi. Saka usatonga nezvakanaka. Zvinoenderana nekubatanidzwa kwemamiriro ekushanda. Plunger globe vharafu: Nenzira iyi vharuvhu yepasi ndeyekusiyana kweiyo yakakosha vharuvhu. Muvharuvhu iyi, disc uye high pressure gedhi mavharuvhu anowanzo gadziriswa maererano ne plunger rationale. Iyo dhisiki inokwenenzverwa kuita plunger uye yakabatana kune hunde. Chisimbiso chinowanikwa nemhete mbiri elastomer yakasvetwa muplunger.
Ziva kunaka kwevharuvhu yeshavishavi
Kusimba kwevhavha ndeyekuedza valve. Inogona kuzadzisa chisimbiso chakanyanya kunoenderana neiyo valve zvinhu, maitiro ekugadzira, maitiro ekugadzira uye mamiriro ekushanda anoshandiswa.
Iyo yekuisa chisimbiso yevhavha uye yekuvharisa kwayo chisimbiso nhanho ndiwo maparamita makuru eiyo index kukosha kuona kureba kwevhavha. Valve haina kunaka kana yakaipa, yakasarudzika yekushanda mamiriro application valve inogona kushandiswa kwenguva yakareba inogona zvakare kushandiswa kwenguva pfupi kwazvo. Saka usatonga nezvakanaka. Zvinoenderana nekubatanidzwa kwemamiriro ekushanda.
The shavishavi vharuvhu kuvhura uye kuvhara chikamu idhisiki rakaita shavishavi ndiro, iyo inotenderera ichitenderedza yaro yepakati mutsetse mukati memuviri wevharuvhu kuvhura nekuvhara kana kugadzirisa vharafu inonzi shavishavi vharafu. Varuvhu yeshavishavi kazhinji isingasviki madhigirii makumi mapfumbamwe kubva pakuvhurwa kusvika pakuvhara. Ivharuvhu neshavishavi tsvimbo hazvina kuvharwa zvakasimba. Kuti uise ndiro ye butterfly, inoderedza mapuraneti inofanira kuiswa pahunde yevharuvhu. Sarudzo yekudzikisa mapuraneti, kwete chete inogona kuita bhobhobhoti nerocking level, kuitira kuti butterfly plate igumise munzvimbo isina kurongeka, asi zvakare inogona kuvandudza maitiro ekushanda evhavha.
Mamiriro ekugadzirwa kwemaindasitiri butterfly valve anogona kusadzivirirwa nekupisa, kunowanikwa kushanda kwekumanikidza chikamu kwakawedzerawo, iyo inonzi dhayamita yevharuvhu yakakura, solenoid valve inogadzirwa nekabhoni simbi, iyo valve plate yekuvhara mhete inogadzirwa nesimbi panzvimbo ye mhete yerabha. Mahombe uye epakati-saizi anoenderera mberi tembiricha yeshavishavi mavharuvhu anogadzirwa nemarata esimbi anopinza, anonyanya kushandiswa mukuenderera mberi tembiricha yepakati chiutsi duct uye pombi yemafuta.
Yakajairika globe mavharuvhu marudzi
1, Angle globe valve muAngle globe valve, iyo mvura inongoda kushandura kutaridzika kamwe chete, kuitira kuti gasi rinomanikidza kuburikidza nevhavha ridiki pane yakakosha chimiro chevharuvhu.
2, DC mhando yeglobe vharafu mukuyerera kwakananga uye Y-yakaita globe vharafu, gedhi reoiri chiteshi ndiro uye nzira huru yekuyerera ichipinda mune slash, iyo yekuyerera nhanho yakaderera pane yekutanga globe vharafu, saka zvinoenderana ne bamboo Ze valve. kuyerera kupikisa kunoenderanawo nediki.
3, plunger mhando yeglobe vharafu: iyi nzira yevharuvhu yepasi ndiyo deformation yeiyo basic globe valve. Muvharuvhu iyi, disc uye high pressure gedhi mavharuvhu anowanzo gadziriswa maererano ne plunger rationale. Iyo dhisiki inokwenenzverwa kuita plunger uye yakabatana kune hunde. Chisimbiso chinowanikwa nemhete mbiri elastomer yakasvetwa muplunger. Zvisimbiso zviviri zve elastomeric zvakapatsanurwa ne clasp uye zvakabatanidzwa kutenderedza plunger nemutoro unowedzerwa kune imwechete kuyerera vharafu nekamwe kuyerera kwevharuvhu nzungu. Elastoseals inobviswa uye inogona kugadzirwa nezvinhu zvakasiyana-siyana. Iyo valve inonyanya kushandiswa "kuvhura" kana "kuvhara" vharafu, asi yakanyatsogadzirwa plungers kana yakakosha clasp inogona zvakare kushandiswa kugadzirisa vharafu.
