Chii chinonzi Butterfly Valve
Vharuvhu remashavi zvinoreva vharuvhu rine chikamu chekuvhara (dhisiki remashavi kana ndiro yemashavi) sedhisiki, rinotenderera rakatenderedza divi remashavi kuti rivhurike uye rivhare. Rinonyanya kushandiswa pakucheka nekukwenya paipi. Chikamu chekuvhura nekuvhara mashavi emashavi emashavi idhisiki remashavi rakaita sedhisiki rinotenderera rakatenderedza divi rayo mumuviri wevharuvhu kuti riwane chinangwa chekuvhura nekuvhara kana kutonga.
1. Maumbirwo evharuvhu yemashavishavi
Vharuvhu yemashavi inonyanya kuumbwa nemuviri wevharuvhu, ndiro yemashavi ...
Kona kubva pakuvhurwa kwakazara kusvika pakuvharwa kwakazara kwevharuvhu remashavi kazhinji isingasviki 90°. Vharuvhu remashavi netsinde remashavi hazvina kugona kuzvivharira. Kuti plate yeshavi riiswe, muchina wekuderedza mashavi emashavi unofanira kuiswa patsinde revharuvhu. Kushandisa muchina wekuderedza mashavi emashavi hakungoiti kuti plate yeshavi riiswe nekukwanisa kumisa plate yeshavi remashavi panzvimbo chero ipi zvayo, asiwo kunovandudza mashandiro evharuvhu.
2. Nheyo yekushanda kwevharuvhu yeshavishavi
Dhisiki revharuvhu idhisiki. Kuburikidza nekutenderera kwetsinde revharuvhu, dhisiki revharuvhu rinotenderera 90° mukati menzvimbo yechigaro chevharuvhu kuti rione kuvhurika nekuvharwa kwevharuvhu. Rinoita basa rekudzima mupaipi. Rinogonawo kugadzirisa kuyerera kwemvura. ??
Zvakanakira zvevharuvhu yemashavishavi: chimiro chiri nyore, vhoriyamu yakareruka, kushanda kuri nyore, kuvhara zvakanaka.
3. Kupatsanurwa kwemavharuvhu eshavishavi
Mavharuvhu eshavishavi anogona kukamurwa kuita mavharuvhu matatu eshavishavi (Triple offset), mavharuvhu eshavishavi anoshanda zvakanyanya (anonziwo mavharuvhu eshavishavi maviri-eccentric), uye mavharuvhu eshavishavi epakati (anonziwo mavharuvhu erabha echigaro cheshavishavi) zvichienderana nechimiro chechimiro.
Zvichienderana nechimiro chekuvhara, zvinogona kukamurwa kuita mhando yekuvhara yakapfava uye mhando yekuvhara yakaoma (mavharuvhu evharuvhu akakamurwa kuita mavharuvhu evharuvhu ane layer yakawanda uye mavharuvhu ebharuvhu esimbi yakachena). Mhando yekuvhara yakapfava inowanzo shandisa rabha ring sealing, uye mhando yekuvhara yakaoma inowanzo shandisa simbi ring sealing.
4. Nheyo dzekusarudza mavharuvhu eshavishavi
-Sezvo kurasikirwa nekumanikidzwa kwemavharuvhu eshavishavi kwakakura zvichienzaniswa nemavharuvhu egedhi nemavharuvhu ebhora, akakodzera masisitimu emapaipi asina zvinodiwa zvakanyanya zvekurasikirwa nekumanikidzwa.
-Sezvo mavharuvhu emapuruguru achigona kushandiswa kudzora kuyerera kwemvura, akakodzera mapaipi anoda kudzora kuyerera kwemvura.
-Nekuda kwekusakwana kwechimiro chevharuvhu remapuruguru nezvinhu zvekuvhara, harina kukodzera masisitimu emapaipi anodziya zvakanyanya uye ane kumanikidzwa kwakanyanya. Tembiricha yekushanda iri pasi pe300°C uye kumanikidzwa kwakaderera kuri pasi pePN40.
-Sezvo vharuvhu remashavishavi rine hurefu hupfupi hwechivakwa uye rinogona kugadzirwa kuita dhayamita hombe, zvinokurudzirwa kushandisa vharuvhu remashavishavi mumamiriro ezvinhu apo hurefu hwechivakwa hunodiwa kuti huve hupfupi kana vharuvhu hombe (senge DN1000 kana kupfuura).
-Sezvo vharuvhu remashavi richigona kuvhurwa kana kuvharwa nekutenderera 90° chete, zvinokurudzirwa kushandisa vharuvhu remashavi mumamiriro ezvinhu apo kuvhura nekuvharwa nekukurumidza kunodiwa.
Pfupiso
Misika yemavharuvhu emapuruvhu yave ichikura nekukurumidza mumakore achangopfuura, uye chinzvimbo chevatengesi vemavharuvhu emapuruvhu chave chichichinja. Patinosarudzafekitari yevharuvhu yemashavishavi, tinofanira kusanganisa zvatinoda isu pachedu, zvakaita semhando, mutengo, sevhisi nezvimwe zvinhu, kuti tisarudzemugadziri wemavharuvhu eshavishaviizvo zvinosangana nezvaunoda.
