Chii chinonzi butterfly valve?
A butterfly valveiri quarter-turn valve. Inoshandiswa kudzora kana kupatsanura kuyerera kwemvura mumapaipi. Butterfly valve uye nekuda kwekugadzirwa kwayo kuri nyore uye kushanda kwakanaka uye nemafambiro ese ehupenyu.
Kwakabva zita reshavishavi vharuvhu: iyo vharafu inoputika yakaumbwa seshavi uye inodanwa kudaro.
1. Chimiro
Butterfly valve ine zvinhu zvikuru zvinotevera:
- Muviri: iyo imba inobata zvese zvemukati uye inobatanidza kune pombi.
- Disc: ndiro yakatsetseka yedenderedzwa mukati memuviri wevhavha, iyo inodzora kuyerera kwemvura nekutenderera.
- Stem: Iyo shaft inobatanidza actuator kune iyo valve flap uye inoibvumira kutenderera.
- Chigaro: Iyo yekuisa chisimbiso mukati memuviri wevharuvhu, uko iyo flapper inosvina chigaro kuti iite hermetic chisimbiso kana yakavharwa kumisa kuyerera kwemvura.
-Actuator: Manual actuators senge zvibato, honye magiya, asiwo magetsi uye pneumatic.
Izvi zvikamu zvinosangana kuita compact, lightweight valve iri nyore kuisa nekuchengetedza.

2. Nheyo yekushanda
Kushanda kwevhavhavhavhavhavha rinobva pane torque uye hydrodynamics. Chinodiwa che torque chinosiyana zvichienderana nekutsikirira musiyano pakati pemativi maviri evharuvhu yeshavishavi uye nzvimbo yevhavhavhavha. Sezvineiwo, torque inokwira pa70-80% vharafu kuvhurwa nekuda kweiyo simba torque yemvura. Hunhu uhu hunoda kunyatsoenderana neactuator.
Pamusoro pezvo, mavharuvhu eshavishavi ane chiyero chakaenzana chekuyerera chimiro che curve, izvo zvinoreva kuti zvigadziriso diki mupepepi zvine mhedzisiro yakakura pane yekuyerera kweyevhavha yekuvhurika pane pedyo nekuvhurwa kwakazara. Izvi zvinoita kuti mavharuvhu eshavishavi aenderane nekudzora kutenderedza mumamiriro ezvinhu chaiwo, zvinopesana nezvinotendwa nevakawanda kuti anongokodzera kushandiswa pa/kudzima.
Butterfly mavharuvhu ari nyore uye anoshanda kushanda:
- Vhura nzvimbo: iyo valve flap inotenderedzwa yakafanana negwara remvura, ichibvumira mvura kuti ipfuure nepakati pese isingapikiswe.
- Yakavharwa nzvimbo: valve inotenderera perpendicular kune nzira yemvura, ichivhara zvachose mvura.
Sevhavhavha yekota-turn, inochinja pakati pekuzaruka uye yakavharwa zvizere nekutenderera chete 90 degrees, nekukurumidza uye nemazvo.

3. Zvakanakira nezvayakaipira
3.1 Zvakanakira mavharuvhu e butterfly
- Yakakwana uye isingaremi: Idiki uye iri nyore kuisa pane mamwe mavharuvhu akadai segedhi kana globe mavharuvhu.
- Economical uye inoshanda: yakaderera mutengo nekuda kwekureruka kuvaka uye kushoma zvinhu.
-Kurumidza kushanda: inogona kuvhurwa kana kuvharwa nekota kutendeuka, yakanakira mhinduro nekukurumidza kune zvinodiwa.
- Mutengo wekugadzirisa wakaderera: zvikamu zvishoma zvinofamba zvinoreva kusapfeka uye kubvarura uye kugadzirisa kuri nyore.
3.2 Kuipa kwemavharuvhu e butterfly
- Kudzivirirwa throttling: haina kukodzera kuyerera kwekudzora kuyerera, kunyanya pakumanikidzwa kwakanyanya, sezvo inogona kutungamirira kumhirizhonga uye kupera uye kubvaruka.
-Njodzi yekudonha: mamwe madhizaini anogona kusasunga zvakasimba semamwe marudzi emavharuvhu uye kune njodzi yekudonha.
- Kudonhedza kudonhedza: kunyangwe kana yakavhurika, iyo valve flap inoramba iri munzira yekuyerera, zvichikonzera kuderera kudiki kwekumanikidza.

4. Zvikumbiro
Mavharuvhu eButterfly anoshandiswa zvakanyanya mumaindasitiri mazhinji nekuda kwekugona kwavo kutonga huwandu hukuru hwemvura nekurasikirwa kushoma kwekumanikidzwa, zvichiita kuti ive yakanakira mapaipi makuru.
Muenzaniso:
- Kugadziriswa kwemvura: kugadzirisa kuyerera kwemvura mumakwenzi ekurapa mvura uye kugovera network.
- HVAC masisitimu: kudzora kuyerera kwemhepo mukudziya, kufefetedza uye mhepo yekumisikidza masisitimu.
- Chemical processing: Inogona kushandiswa kubata akasiyana siyana emakemikari nekuda kwekuenderana kwezvinhu.
- Chikafu uye Chinwiwa: chehutsanana maitiro nekuda kwekuchenesa kuri nyore.
-Oiri uye gasi: inogadzirisa uye inoparadzanisa kuyerera mumapaipi uye kuchenesa.
