Ona Mufananidzo Mukuru
Kune zvakare kudiwa kuri kukura kwemavharuvhu ebhora sezvo nyika ichitsvaga mamwe manyuko esimba.Kunze kweChina, mavharuvhu ebhora anogona kuwanikwawo muIndia.Iko hakuna kuramba kukosha kwemavharuvhu akadaro mune chero maindasitiri pombi masisitimu.Asi, zvakawanda zvinofanira kudzidzwa pamusoro pemavharuvhu ebhora, uye unofanira kuzviziva usati waishandisa.Ichi chinyorwa chichakubatsira iwe kunzwisisa mavharuvhu ebhora zvakanyanya kuti iwe udzidze kana aya akakodzera maapplication ako.
Zvaunofanirwa Kuziva nezveBhora Mavhavha
Imwe yeanonyanya kushandiswa mavharuvhu eindasitiri, mavharuvhu ebhora anowanzo shandiswa mukusunga zvikumbiro zvekuvhara.Ivharuvhu yebhora yakawana zita rayo kubva kune hollowed-out sphere component inobvumira midhiya nzira painovhura kana kuivhara kana yakavharwa.Idzi inhengo dzekota-yekutendeuka mhuri yemaindasitiri mavharuvhu.
Ivhavhavha yebhora inowanzoshandiswa mumaindasitiri mazhinji saka hazvishamise kuwana kuti kudiwa kwayo kwakakwira.Mazuva ano, unogona kuwana mhando yepamusoro yakagadzirwa muChina bhora mavharuvhu kana bhora mavharuvhu anogadzirwa muIndia.
Common Ball Valve Features
Mazhinji mavharuvhu emhando dzebhora anogovana zvakafanana sezvakataurwa pazasi:
# Swing cheki - izvi zvinodzivirira kudzosera kumashure kwenhau
# Vavha inomira - izvi zvinongobvumira 90-degree kutendeuka
# Anti-static - izvi zvinodzivirira static magetsi kuvaka izvo zvinogona kukonzera sparks
# Moto-yakachengetedzeka - chigaro chesimbi chechipiri chakavakwa kuti chiite sezvigaro zvekuwedzera mune yakanyanya-tembiricha maapplication.
Zvakanakira uye Zvakaipa zveBhora Valve
Mavharuvhu ebhora akanakisa kushandisa kana sisitimu ichida kuvhurwa nekukurumidza nekuvhara.Izvi zvakare zvinobatsira mumashandisirwo apo inoda chisimbiso chakasimba pasina kufunga nezve kumanikidza kwemukati.
Nekudaro, mavharuvhu ebhora ane mashoma ekudhonza matinji.Muchokwadi, izvi hazvikurudzirwe kudzora kuyerera kwenhau.Mavharuvhu ebhora ane zvigaro zvakafumurwa zvishoma, izvo zvinogona kupera nekukurumidza kana slurries inoshandiswa.Izvi zvakare zvakaoma kuvhura nekukurumidza uye nemaoko kana kudzvanywa kwakakwira.
Common Ball Valve Materials
Mavharuvhu ebhora anouya mumhando dzakasiyana.Zvichienderana nemhando yekushandiswa, mavharuvhu ebhora anowanzo kuumbwa kana kukandwa pachishandiswa simbi, simbi isina tsvina, uye mamwe simbi alloys.Zvigaro zvevharuvhu bhora zvinogona kugadzirwa neye elastomeric zvinhu zvakaita sePTFE kana simbi, kazhinji simbi isina tsvina.
Ball Valve Zvikamu
Kunyangwe paine akati wandei akasiyana evharuvhu yebhora, pane zvishanu zvakajairika zvikamu zviripo mumavharuvhu ese ebhora sezvinoonekwa mumufananidzo uri pazasi:
# Muviri
Muviri unobata zvinhu zvese pamwechete
# Chigaro
Chigaro chinovhara valve panguva yekuvhara
# Bhora
Bhora rinobvumira kana kuvhara mafambiro ezvenhau.
#Actuator
Iyo actuator kana lever inofambisa bhora kuti rekupedzisira rivhure kana kuvhara.
# Dzinde
Dzinde rinobatanidza nhanho nebhora.
Ball Valve Ports
Kazhinji, mavharuvhu ebhora ane zviteshi zviviri.Asi nekuuya kwemasevhisi matsva, mavharuvhu ebhora anogona kunge ane zviteshi zvina.Aya anowanzo kunyorwa senzira mbiri, nzira nhatu kana mana-nzira bhora mavharuvhu.Ivhavha yenzira nhatu inogona kuva ne-L-configuration kana T-configuration.
Ball Valve Kushanda Mechanism
Bhora dhisiki rinovhurwa kana kuvharwa nekushandura actuator chikamu chekota kana 90-degrees.Kana iyo lever ichienderana nekuyerera kwe media, valve inobvumira iyo yekupedzisira kupfuura.Kana iyo lever ikava perpendicular kuyerera kwe media, valve inovhara kuyerera kweiyo yekupedzisira.
Ball Valve Classifications
Mavharuvhu ebhora anonyatso kukamurwa munzira dzinoverengeka.Iwe unogona kusangana nemapoka evharuvhu zvichienderana nehuwandu hwezvikamu kana rudzi rwemavharuvhu ebhora.
Kubva paHousing
Iwe unogona kuisa bhora mavharuvhu zvichienderana nehuwandu hwezvikamu izvo miviri yavo ine.Iyo yakachipa pakati pevatatu, iyo-chidimbu bhora vharafu inogadzirwa nebhuroko rimwe chete resimbi.Izvi hazvigone kuparadzaniswa kuti zvicheneswe kana kugadzirisa.Imwe-chidimbu bhora mavharuvhu akakodzera kune yakaderera-kudzvanywa maapplication.
Kune rumwe rutivi, maviri-chidimbu bhora valve yakagadzirwa nezvidimbu zviviri zvakabatanidzwa neshinda.Rudzi urwu runofanira kubviswa zvachose kubva papombi paunenge uchicheneswa kana kutsiviwa.Pakupedzisira, zvikamu zvevatatu-chidimbu bhora valve zvakabatanidzwa kuburikidza nemabhoti.Kuchengetedza kunogona kuitwa pavhavha kunyange ichiri kusungirirwa pombi.
Kubva paDisiki Dhizaini
Iyo dhizaini yebhora chikamu chikuru chebhora mavharuvhu.Yakanyorwa nemazvo nekuti bhora rakaturikwa pamusoro pehunde, vharafu yebhora inoyangarara ndiyo inonyanya kugadzirwa pachikamu ichi.Parinovhara, bhora rinofamba rakananga kuzasi kwerwizi.Mutoro wekumanikidza unobatsira kuvhara valve zvakasimba.
Kune rimwe divi, trunnion yakasimudzwa bhora dhizaini inobatwa yakatsiga nema trunnions ari pazasi pebhora.Chishandiso chakanyanya kufanira chetrunnion chakaiswa bhora mavharuvhu ndeaya ane mazaruro akakura uye akakwira-pressure siyana, kazhinji anodarika 30 bar.
Kubva paPipe Diameter
Mavharuvhu ebhora anogonawo kuiswa muzvikamu zvichienderana nehukuru hwekubatanidza maererano nehupamhi hwepombi.Iyo yakaderedzwa bore ball valve zvinoreva kuti dhayamita yevharuvhu idiki saizi imwe pane yepombi.Izvi zvinokonzeresa kuderera kwekumanikidza.Rimwe-chidimbu bhora mavharuvhu kazhinji ane redecate bore mhando.
Mhando dzemhando dzakakwana dzine dhayamita yakafanana neyemapombi.Zvakanakira rudzi urwu zvinosanganisira kusamanikidzwa kurasikirwa uye nyore kuchenesa.Mhando dzakakwana dzebore dzinodhura zvakanyanya nekuda kwehukuru hwevhavha.Chekupedzisira, Iyo V-yakaita mhando ine V-yakaita gomba iyo inogonesa chaiyo kutonga kwemvura pese pese vharafu yakavhurika.
Ball Valve Applications
Mavharuvhu ebhora anowanzo kuwanikwa mune zvakasiyana siyana zvekushandisa.Kazhinji kazhinji, waizovawana mumasisitimu anoyerera pangarava, masevhisi anoparadza uye masevhisi ekudzivirira moto.Izvi hazvishandiswe mumashandisirwo uko kusvibiswa iri nyaya senge iyo iri mumasevhisi ekugadzirisa chikafu.Mavharuvhu ebhora akaoma kuchenesa.
Summary
Mavharuvhu ebhora ari kusimukira pamwe chete nemaindasitiri aya akabatana nawo.Kuva vatengi, kuzvidzidzisa pamusoro peiyo bhora vharafu yakakosha.
