Yintoni naivelufa butterfly?
Ivalve yebhabhathane ibizwa ngokuba yivalve yebhabhathane kuba imilo yayo ifana nebhabhathane.I-actuator ijikeleza ipleyiti yevalve 0-90 degrees ukuvula nokuvala ivalve, okanye ukulungelelanisa ngokufutshane izinga lokuhamba.
Yintoni naivalve yebhola?
Iivalvu zebhola zikwasetyenziswa kwimibhobho yokulawula iivalvu ezilawula ukuhamba kolwelo.Ngokuqhelekileyo basebenzisa ingqukuva enomngxuma ukulawula ukuhamba kolwelo, olunokuthi ludlule okanye luvalwe njengoko ingqukuva ijikeleza.
Njengamacandelo okulawula ulwelo, iivalve zebhabhathane kunye neevalvu zebhola zinokusetyenziselwa zombini ukudibanisa nokusika okuphakathi kumbhobho.Yintoni umahluko, iingenelo kunye nezingeloncedo?Ngezantsi sihlalutya kwisakhiwo, ububanzi besicelo, kunye neemfuno zokutywinwa.
1. Isakhiwo kunye nomgaqo
- Inxalenye yokuvula nokuvalwa kwevalve yebhabhathane, ipleyiti yevalve, njengoko lisitsho igama, sisiqwenga esimilise okwepleyiti enobunzima obuthile, ngelixa indawo yokuvula nokuvalwa kwevalve yebhola iyingqukuva.
- Iivalve zebhabhathane zilula kwaye zinesakhiwo esibambeneyo, ngoko ke zikhaphukhaphu ngobunzima;ngelixa iivalve zebhola zinomzimba omde kwaye zifuna indawo enkulu xa uvula kwaye uvala.Zikholisa ukuba zikhulu kwaye zinzima.
- Xa ivalve yebhabhathane ivuleke ngokupheleleyo, ipleyiti yevalvu ijikeleza idibane necala lokuqukuqela, nto leyo evumela ukuhamba okungathintelwanga.Xa ivalve yebhabhathane ivaliwe, ipleyiti yevalve ikwicala eliphakathi, ngaloo ndlela ivalela ngokupheleleyo ukuhamba.
- Xa ivalve yebhola egcweleyo ivuleke ngokupheleleyo, imingxuma ihambelana nombhobho, ivumela ulwelo ukuba ludlule.Kwaye xa ivaliwe, ibhola ijikeleza i-90 degrees, ivimbela ngokupheleleyo ukuhamba.Ivalve yebhola egcweleyo inciphisa ukuhla koxinzelelo.
2. Ubungakanani besicelo
- Izivalo zebhabhathane zingasetyenziselwa kuphela ukuhamba ngeendlela ezimbini;iivalve zebhola zisenokusetyenziswa njengabaphambukisi bendlela-ntathu ukongeza kwindlela yokuhamba ngeendlela ezimbini.
- Iivalvu zebhabhathane zikulungele ukuvala/ukucima imibhobho yoxinzelelo oluphantsi;iivalvu zebhola zingasetyenziselwa ulawulo lokuhamba oluchanekileyo kubushushu obuphezulu kunye neemeko zoxinzelelo.
- Iivalve zebhabhathane zisetyenziswa ngokubanzi kunyango lwelindle, ukusetyenzwa kokutya, iinkqubo zeHVAC, iinkqubo zokupholisa umoya kunye neminye imimandla;iivalvu zebhola zisetyenziswa ikakhulu kwi-petroleum, igesi yendalo, ishishini lemichiza, isinyithi, amandla ombane kunye namanye amasimi oshishino.
3. Ukutywinwa
- Izivalo zebhabhathane ezitywina ngokuthambileyo zixhomekeke kwizitulo zevalvu ezilastiki ezifana nerabha okanye i-PTFE ukwenza itywina ngokucinezela ipleyiti yevalve.Kukho ithuba elithile lokuba eli tywina liya kuthotywa ngokuhamba kwexesha, okunokubangela ukuvuza.
- Iivalvu zebhola zihlala zinentsimbi ukuya kwintsimbi okanye isitywina esithambileyo esinikezela isitywina esithembekileyo nasemva kokusetyenziswa kwexesha elide.
Isishwankathelo, iivalve zebhabhathane kunye neevalve zebhola nganye ineengenelo kunye nokungona kwayo, kwaye yeyiphi ivalve yokukhetha ixhomekeke kwimiba ethile yesicelo kunye neemfuno.
INkampani yeValve ye-ZFA ngumzi-mveliso ojongene nokuvelisa iivalvu ezahlukeneyo zamabhabhathane.Ukuba unayo nayiphi na imibuzo, nceda uzive ukhululekile ukuqhagamshelana nathi.
