Mavharuvhu emashavishavi anoita basa rakakosha kana zvasvika pakudzora kufamba kwemvura mumapombi. Mukushandiswa kwemaindasitiri,Mavharuvhu ePVC shavishaviisarudzo inozivikanwa nekuda kwekugara kwenguva refu uye kushanda zvakanaka. Muchinyorwa chino, tichaongorora zvakadzama mashandiro emavharuvhu emapuruvheta, kunyanya ayo akagadzirwa nePVC, uye toongorora kuti sei achikosha mumaindasitiri akasiyana-siyana.

Basa revharuvhu reshavishaviiri nyore asi yakakosha zvikuru. Chaizvoizvo, inodzora kufamba kwemvura nekushandisa dhisiki inonzi "butterfly" iri pakati pepombi. Kusiyana nemavharuvhu ebhora, anoshandisa bhora kudzora kufamba kwemvura, dhisiki yevharuvhu yebhatafurayi inoiswa pamugodhi unotenderera. Kana vharuvhu iri panzvimbo yakavharwa, dhisiki yacho inomira yakatarisana nekuyerera kwemvura, zvichivhara mvura yacho zvakanaka. Kana yakavhurika, dhisiki inotenderera yakatarisana nekwainoenda mvura, zvichiita kuti mvura ipfuure nepakati.

Zvinhu zvakagadzirwa nePVC zvinowedzera kushanda uye kuvimbika kumavharuvhu eshavishavi. PVC, kana kuti polyvinyl chloride, ipurasitiki inodziya ine simba rekudzivirira makemikari uye yakakodzera kushandiswa kwakasiyana-siyana. Kuwedzera pakudzivirira makemikari anoparadza, PVC yakareruka, iri nyore kuisa, uye inodhura zvishoma, zvichiita kuti ive chinhu chakanakira mavharuvhu eshavishavishavi.

Mavharuvhu ePVC butterfly anozivikanwamunzvimbo dzemaindasitiri uko mvura inoyerera nengura inowanzo pararira. Kukwanisa kwayo kutsungirira makemikari akaomarara uye tembiricha yakanyanya kunoita kuti ive chinhu chakakosha mumafekitori ekugadzirisa makemikari, nzvimbo dzekuchenesa mvura uye masisitimu ekuchengetedza mvura yakasviba. Kugara kwenguva refu uye kugara kwenguva refu kwemavharuvhu ePVC kunoita kuti ikwanise kupa sevhisi yenguva refu uye yakavimbika munzvimbo dzinoda kushanda nesimba.

Pamusoro pezvo, mavharuvhu ePVC butterfly anoshandiswawo zvakanyanya kutakura mvura nezvimwe zvinwiwa zvisingakanganisi. Pamusoro payo pakadzikama panoderedza kudonha kwesimba uye nyonganyonga, zvichiita kuti ive sarudzo isingadyi simba zvakanyanya yekudzora mvura. Izvi zvinoita kuti mavharuvhu ePVC butterfly ave sarudzo inozivikanwa muHVAC systems, irrigation systems uye water shipping networks.

Chimwe chinhu chakakosha pakushanda kwemavharuvhu eshavishavi, kusanganisira ayo akagadzirwa nePVC, kugona kwawo kudzora kuyerera kwemvura. Nekugadzirisa kona yedhisiki mukati mevharuvhu, mwero wekuyerera kwemvura unogona kudzorwa nemazvo. Izvi zvinoita kuti mavharuvhu eshavishavi ave akasiyana-siyana sezvo achigona kushandiswa kudzora kuyerera kwemvura mumabasa akasiyana-siyana emaindasitiri, zvichiita kuti zvive nyore kushanda uye kushanda zvakanaka.

Muchidimbu, basa remavharuvhu emabhatafura, kunyanya ayo akagadzirwa nePVC, rinokosha zvikuru mukutonga kwemvura mumaindasitiri. Kugona kwayo kudzora kuyerera kwemvura, kutsungirira makemikari anoparadza uye kupa basa rakavimbika kunoita kuti ive chinhu chakakosha mumaindasitiri akawanda. Ingave kugadzirisa kuyerera kwemakemikari anoparadza mumafekitori ekugadzirisa kana kudzora kupararira kwemvura mumasisitimu emaguta, mavharuvhu emabhatafura ePVC anoita basa rakakosha mukuona kuti maitiro akawanda emaindasitiri anofamba zvakanaka uye nemazvo.
