Chii chinonzi Butterfly Valve: Mirayiridzo Yakadzama Inoshanda

Chii chinonzi Butterfly Valve

A vharuvhu yeshavishaviivharuvhu inotenderera kwekota ine dhisiki rinotenderera (puratifomu yeshavishavi) yakabatana nedanda repakati. Dhizaini iyi diki inobvumira kudzora kuyerera kana kupatsanurana kwemapaipi nekukurumidza. Anoshandiswa zvakanyanya mumaindasitiri, mavharuvhu eshavishavi anobudirira mukushandisa kunoda mhinduro dzisingadhuri uye dzakareruka dzine kuderedzwa kwesimba.

Maumbirwo eVhavha yeBhatafurayi: Zvikamu 4 Zvikuru

1. Muviri weVharuvhu: Housing yakagadzirwa ne cylindrical (simbi yakaumbwa, simbi isingasvibi, kana simbi yakapfava) ine magumo akapfava/akapfava/akakweshwa.

2. Dhisiki reVharuvhu: Kuyerera kweplate inotenderera - inowanikwa muchimiro chakabatana, chakapetwa kaviri/katatu.

3. Hunde: Inobatanidza actuator kudhisiki kuti itumirwe torque.

4. Chigaro: Kuvhara pamusoro (rabha yakapfava, PTFE, kana simbi) zvichiita kuti mvura ivhare zvakasimba.

Mavharuvhu eButterfly Anoshanda Sei

Mavharuvhu eshavishavi zvinhu zvakakosha muhurongwa hwemazuva ano hwekudzora mvura, anokosheswa nekuda kwekureruka kwawo, dhizaini diki, uye kushanda nekukurumidza. Asi vharuvhu iyi inoshanda sei chaizvo?

Nheyo Yekushanda Yepakati: Dhisiki Inotenderera

Mwoyo wevharuvhu remashavishavi idhisiki rakatenderera (kana kuti vane) rakaiswa padanda rinotenderera mukati mebhomba repombi. Kudzora mvura kunowanikwa zvizere kuburikidza nekufamba kwakakosha kwedhisiki:

Dhisiki iyi inotenderera 90° pakati pe:

-Vhura Zvizere: Dhisiki inorongeka zvakaenzana nekuyerera (kurasikirwa kushoma kwekumanikidzwa)

-Yakavharwa Zvizere: Madhisiki anoyerera akatarisana nepaipi

Kutanga & Kuyerera Kwemvura: Kutenderera kusvika pakubvumira Kuyerera Kwemvura

• Kana ikashandiswa (nemaoko kuburikidza neruoko, kana otomatiki kuburikidza nemagetsi/pneumatic actuators), tsinde rinotenderera dhisiki kubva panzvimbo yaro yakavharwa (yakatarisana nekuyerera) kuenda panzvimbo yakavhurika.

• Sezvo dhisiki richitenderera (kazhinji kubva pa0° kusvika pa90°), rinofamba kubva pachigaro chevharuvhu, zvichiita kuti mvura ifambe ichitenderedza mipendero yayo uye/kana kuti ipinde nepaburi repakati kana riripo.

• Kona yekuvhura inoenderana zvakananga nekukwanisa kuyerera, zvichibvumira kugadziriswa kwakanyatsoenderana nezvinodiwa nesystem.

Kudzora Kuyerera Kwakarurama: Angle Inorayira Mwero

• Simba guru remavharuvhu eshavishavi ndiko kugona kwawo kupinza zvinhu zvakanaka. Nekudzora kona yekutenderera kwedhisiki, vanoishandisa vanowana kudzora kuyerera kwemhepo.

• Pakutenderera kunenge 90° (diski iri pamwe chete nekuyerera kwayo), dhisiki iyi haivharidzike zvakanyanya, ichipa kuyerera kwepombi pedyo nekuzara kwayo uye mwero wepamusoro wekuyerera kwayo.

• Pamakona ari pakati nepakati (semuenzaniso, 30°, 45°, 60°), dhisiki iyi inovhara zvishoma nzira yekuyerera kwemvura, ichideredza nzvimbo yekuyerera kwemvura uye ichigonesa kudzora kuyerera kwemvura zvakanaka.

Kuvhara Kwakanaka: Kuvhara Kuyerera

Kuti kumisa kuyerera zvachose, actuator inotenderedza dhisiki kudzokera kunzvimbo ye0° (yakatarisana nekuyerera).

Munzvimbo iyi, divi redhisiki rinodzvanya zvakasimba pachigaro che elastomeric chinosimba (semuenzaniso, EPDM, Nitrile, PTFE) chakabatana kana kuchengetwa mumuviri wevharuvhu, zvichiita kuti chisimbiso chive chakasimba kuti chisapararire.

Mamwe Mashandiro: Mashandisirwo Ekudzora Mazinga

Kunze kwekungobatidza nekudzima kana kukanda, mavharuvhu emapuruguru dzimwe nguva anogona kushandiswa kudzora nhanho (musoro) mumatangi kana matangi emvura. Nekugadzirisa angle yedhisiki, mwero wekubuda kwemvura unogadziriswa, zvichikanganisa zvisina kunanga mwero wemvura iri kumusoro.

Hunhu Hukuru hweKushanda & Zvinhu Zvinoita Kuti Sarudzo Ive Yakanaka:

Kunzwisisa misimboti iyi yekushanda kunoratidza zvinhu zvakakosha zvekushanda zvakakosha pakusarudza uye kushandisa mavharuvhu nemazvo:

√Kuderera Kwekumanikidzwa (Kurasikirwa):Mavharuvhu eshavishavi anoratidza kudonha kwakaderera kwedzvinyiriro kana akavhurika zvizere (nekuda kwekuvharika kushoma) uye zvinobudirira kudonha zero kana akavharika (full seal). Zvisinei, munzvimbo dzakavhurika zvishoma (throttling), dhisiki inogadzira kutenderera kwakakosha uye kukanganiswa kwekuyerera kwemhepo, zvichikonzera kurasikirwa kwakanyanya kwedzvinyiriro zvichienzaniswa nemavharuvhu akazara senge mavharuvhu egedhi. Ichi chinhu chakakosha pakushandisa simba zvakanaka mukushanda kwethrottling.

√Midhiya Yakakodzera:Mavharuvhu emashavishavi anonyatsonaka nemafuta akachena, magasi, uye utsi - zvinhu zvinokwanisa "kuchekwa" nyore nyore nedhisiki.

√Madota kana midziyo ine zvinhu zvakasimba zvakawanda:Zvidimbu zvinokwenya zvinogona kukanganisa mupendero wedhisiki uye kukuvadza chigaro chakapfava, zvichiita kuti chivhariso chisashande zvakanaka. Tinokukurudzira kuti ushandiseMavharuvhu eSimbi eChigaro cheSimbikana Vharuvhu yeGedhi reSlurry

Kazhinji HAZVIKUMBIDZWE pa:

χMvura ine viscous yakawanda kana kuti media inokwanisa kuita crystallization: Izvi zvinogona kukonzera kunamira, kudzivirira kuvharika zvachose, kana kukuvadza chigaro. Tinokurudzira kushandisa mavharuvhu eSegment Ball.

Sei Uchifanira Kusarudza Vharuvhu Yeshavishavi? Pfupiso Yezvakanakira:

→ Kapfupi & Kareruka:Inoda nzvimbo shoma yekuisa.

→ Kushanda Nekukurumidza:Kushanda nekukurumidza kwe90° kunoita kuti kuvhurika/kuvhara kuvhurike nekukurumidza.

→ Mari Inoshanda:Mutengo wekutanga wakaderera uye kazhinji mari yekugadzirisa yakaderera kana tichienzanisa nemhando dzakawanda dzemavharuvhu.

→ Kurovera Kwakanaka Kwazvo:Inopa kutonga kwakanaka pamusoro pehuwandu hwemvura inoyerera.

→ Kudonha Kwekumanikidzwa Kwakaderera (Kuvhurika Kwakazara): Inoshanda zvakanaka pakushandisa magetsi akazara.

→ Chisimbiso Chinosunga Mabara (Chine Chigaro Chinosimba):Kuvharwa kwakavimbika kwemvura zhinji dzemumaindasitiri.
