Resilient Seated Butterfly Valve Inoshanda Sei?

Ona Mufananidzo Mukuru
Imwe yeanonyanya kushandiswa mavharuvhu mupombi system.Nhengo yekota-turn mhuri, butterfly mavharuvhu anofamba achitenderera.Disiki revharuvhu yeshavishavi rakaiswa padzinde rinotenderera.Kana yakavhurika zvakazara, dhisiki iri pa90-degree angle maererano neiyo actuator.Iri vharuvhu rakakodzera kuyerera kwakakura nekudzika kwakaderera pamwe chete neve viscous media ine hombe yakasimba muzana.

Zvinoumba butterfly valve zvinosanganisira:
-Kuvhura kuri nyore
- Nyore kuisa
- Nyore kuchengetedza
-Isingadhure kuisa
- Inoda nzvimbo shoma
- Mutengo wekugadzirisa wakaderera
-Inokodzera maapuro mavharuvhu makuru

Imwe nzira yekuisa mumapoka mavharuvhu e butterfly inobva pakugadzirwa kwechigaro.Imwe dhizaini yakadaro kuve chigaro chakasimba.Sezviri kutaurwa, chinyorwa chino chinoongorora zvakadzama magadzirirwo evharuvhu yeshavishavi rinokwanisa kugara.Inogadzirisawo mutsauko pakati pesimbi yakagara butterfly valve uye resilient seat butterfly valve.

Mhando dzeButterfly Valves

Sezvambotaurwa, mavharuvhu eshavishavi akaiswa mumapoka munzira dzakawanda.Chikamu chega chega chinoshanda zvakanaka nemashandisirwo chaiwo.Sezvo paine nzira inopfuura imwe yekuisa mavharuvhu, unogona kugadzirisa mavharuvhu eshavishavi zvichienderana nezvaunoda uye kushandisa.

Butterfly Mavharuvhu neKubatanidza Type

Iyi kupatsanurwa kunobva pakuti vharafu yakabatana sei nemapombi.

Wafer Type

Iyi ndiyo yakanyanya hupfumi uye yakareruka.Iyi dhizaini ine chinangwa chekudzivirira bi-directional differential pressures uye backflows.Kune maviri mapaipi flanges anoisa sandwich valve.Vanoisa chisimbiso uye vanobatanidza valve kune pombi system kuburikidza nemabhoti.Kuti uvhare chisimbiso chakasimba, kune O-mhete uye gaskets akaiswa kumativi ose evhavha.

Ivharuvhu yerudzi rweshavishavi ine magumbeze akaiswa kunze nekutenderedza muviri wevharuvhu.Izvi zvinowanzo shandiswa mumasevhisi ekupedzisira kana mumashandisirwo anongoda kuderera.Malugs akaiswa thread.Mabhoti, anofanana neaya mapaipi, anobatanidza valve kune pombi.

Butt-Welded

Butt-weld butterfly vharuvhu ine zvinokochekera zvakanangwa papombi.Iri rudzi rwevharuvhu rinonyanya kushandiswa kune yakakwira-kumanikidza maapplication.

Flanged

Rudzi urwu runoratidzwa nekuve nechiso cheflange kumativi ese.Apa ndipo panosangana mavharuvhu.Iyi dhizaini yakajairika pakati pemavharuvhu makuru.

Butterfly Mavharuvhu neDisc Alignment Type

Rudzi urwu rwekuronga runobva pakugadzirwa kwechigaro uye kona iyo chigaro chinosungirirwa kune disc.

Concentric

Iyi ndiyo yakanyanya dhizaini pakati peiyo inosanganisirwa muchikamu ichi.Izvi zvinonziwo resilient-seated butterfly valve kana dzimwe nguva zero-offset butterfly valve design.Dzinde inopinda nepakati pe disc uye chigaro.Chigaro chiri mudhayamita yemukati yemuviri.Kazhinji yenguva, mavharuvhu akapfava akagara anoda iyo concentric dhizaini.

Kaviri Offset

Izvi dzimwe nguva zvinodaidzwa kuti double eccentric butterfly valve.Iyo dhisiki haina kuenderana nepakati pemuviri nevhavha yese.Izvi zvinofambisa chigaro kunze kwechisimbiso panguva yekushanda.Iyi nzira inoderedza kukanganisa kwekukwenya pane butterfly disc.

Triple Offset

Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhafhizwawo sevhavhavhavhavhavhavhavhavhavhavha eccentric.Nzvimbo yechigaro inogadzira imwe offset.Iyi dhizaini inogonesa kufamba kusina friction ye disc panguva yekushanda.Izvi zvinowanzoitika kana zvigaro zvakagadzirwa nesimbi.

Butterfly Valve Basa

Butterfly mavharuvhu ndeimwe yeaya mavharuvhu anogona kushandiswa kupuruzira uye kuvhara kana kudzima.Inogona kuenzanisa huwandu kana kuyerera kwe media inopfuura nepavhavha pane yakapihwa oparesheni.Nezvekusimba kwayo kuvharwa kwemaitiro, iwe unofanirwa kufunga nezvehukuru hwemutsara pamwe neiyo yakaderera inodiwa yekudonha inodonha kana vharuvhu yakavhurika.

Kuve vharuvhu yekudzora, shavishavi vharafu inoda maverengero chaiwo uye mvumo yezvinoda midhiya uye maverengero akadai sekuyerera kwezvinodiwa, kudonhedza madonhwe, uye vanofarira.

Mashandiro Akasimba Akagara Butterfly Valve Inoshanda

A resilient seated butterfly vharuvhu inoratidzwa nedzinde rinoboorwa mudisiki uye rakanamirwa kuzasi kwevharuvhu.Nguva zhinji, zvigaro zverudzi urwu rwevharuvhu zvinogadzirwa nerabha, saka, izwi rekuti resilient.
Saka nekudaro, iyo disc inotsamira pane yakakwirira yekubata kugona kwechigaro uye chigaro chekuvhara-kuvharika kwakasimba.Nemhando iyi yedhizaini, chigaro-ku-chisimbiso kubata chinotanga panosvika 85-degree kutendeuka.

Resilient seated butterfly mavharuvhu anogadzirwa nechidimbu chimwe.Izvi zvinowedzera simba revhavha pamwe nekuderedza uremu hwayo.Chigaro cherabha-chekumashure chinoita kuti zvive nyore kuisa kunyange kana shavishavi vharafu iri panze.Nekuda kwechimiro chechinhu chacho, ine yakavimbika yekuisa chisimbiso.

Kuti chigaro chivhare chisimbiso, chinofanira kunyatsokwana uye kuvhara kumucheto kwe disc.Izvi zvinoita kuti butterfly valve disc isazungunuke.Izvi zvinobva zvamisa kuyerera.Imwe nzira yekuitarisa ndiyo dhisiki inobata pachigaro chiri padhayamita yemukati yevharuvhu.

Resilient Seat Butterfly Valve Material

Zvigaro zvevharuvhu yeshavishavi zvinogona kuiswa muzvikamu zviviri.Izvi ndizvo zvinhu zvakapfava uye simbi-yakagara butterfly valve.The resilient seat butterfly valve ndeyekare.Inoshandiswa kune zvisiri zvakakosha, zvigaro zveshavishavi zvakadaro zvinogona kugadzirwa kubva kuEPDM (ethylene propylene diene terpolymer), VITON, uye acrylonitrile-butadiene rubber.

Musiyano pakati peMetal Seated Butterfly Mavharuvhu uye Resilient Seated Butterfly Mavharuvhu

Mavharuvhu eshavishavi anogadzika kana kuti akatsikirira anogara akapfava.Mukuenzanisa, eccentric kana iyo ine zvigadziriswe, inogadzirwa nezvigaro zvesimbi, kunze kwekugadzirwa kwekaviri.Izvi zvinogona kuva nezvinhu zvakapfava kana simbi.Mukupesana nedhizaini yakapetwa kaviri, iyo concentric valve dhizaini yakachipa.

Pakuvharika kwakasimba, pane nguva dzose kubvumidzwa kwesimbi kune mavharuvhu e butterfly.Kune rimwe divi, inogara iri zero leakage yevharuvhu yeshavishavi yakagadzikana, kunze kwekunge chigaro chakanganiswa.

Zvakare, neyakagadzika chigaro dhizaini, mavharuvhu eshavishavi akadaro anoregerera zvakanyanya kune yakakora media.Pasinei nemarara akabatwa pakati pezvikamu zvevharuvhu, chigaro chinogona kuramba chichipa kusimba kwechisimbiso.Zviri nyore zvakare kutsiva zvigaro zvakapfava zvichienzaniswa nezvigaro zvesimbi kana izvi zvisina kunaka.Zvisinei, nokuda kwekugadzirwa kwechigaro chesimbi, zvigaro zvinogona kunamatira panzvimbo kana pane marara pakati pezvikamu zvemukati zvevharuvhu.
