PVC (polyvinyl chloride) uye UPVC (unplasticized polyvinyl chloride) zvinhu zvinoshandiswa zvakanyanya mukugadzira akasiyana mavharuvhu ekuisa.

PVC (polyvinyl chloride) uye UPVC (unplasticized polyvinyl chloride) zvinhu zvinoshandiswa zvakanyanya mukugadzira zvakasiyana-siyana mavharuvhu. Zvishandiso izvi zvinozivikanwa nekusimba kwazvo, corrosion resistance, uye kukwanisa kutenga, zvichiita kuti ive sarudzo dzakakurumbira kune dzakasiyana siyana dzekushandisa. Imwe yeanonyanya kushandiswa mavharuvhu fittings akagadzirwa kubva PVC uye UPVC ndiyo butterfly valve.

Nheyo yekushanda yePVC butterfly valve yakavakirwa padhizaini iri nyore asi inoshanda. Rudzi urwu rwevharuvhu rine disc, inozivikanwawo se "butterfly," iyo yakamira pakati pepombi. Iyo dhisiki yakabatanidzwa kune tsvimbo kana shaft inosvika kunze kwevhavha, ichibvumira kushandiswa kwemanyore kana otomatiki.

Kana iyo valve iri munzvimbo yakavharwa, iyo disc inotenderera kune kuyerera kwemvura, inonyatso kuvharira nzira yenhau. Kusiyana neizvi, kana vharuvhu iri munzvimbo yakazaruka, dhisiki inofananidzwa nekuyerera, ichibvumira nzira isina kuvharwa yemvura. Iyi nzira yakapfava inobvumira kukurumidza uye kwakaringana kutonga kwekuyerera, kuita PVC butterfly mavharuvhu akakodzera kune akasiyana maapplication.

Kushandiswa kwePVC uye UPVC zvinhu mukuvaka mavharuvhu e butterfly kunopa akawanda mabhenefiti. Zvinhu izvi zvinoshingirira mukuora, zvichiita kuti zvive zvakanakira kushandiswa mumashandisirwo apo vharafu inosangana neanehasha kana corrosive media. Pamusoro pezvo, PVC neUPVC hazvina huremu uye zviri nyore kuisa, zvichiita kuti ive mhinduro inodhura kune akasiyana maindasitiri uye ekutengesa maapplication.

Uyezve, PVC uye UPVC butterfly mavharuvhu anozivikanwa nekudzikira kwekugadzirisa zvinodiwa uye hupenyu hurefu hwesevhisi, zvichiita kuti ive sarudzo yakavimbika kune masisitimu ekudzora mvura. Aya mavharuvhu anowanikwawo muhukuru hwakasiyana-siyana uye zvigadziriso kuti zvienderane nezvinoda kuyerera zvakasiyana uye zvinodiwa zvekuisa.

Mukupedzisa, PVC uye UPVC butterfly mavharuvhu zvinhu zvakakosha mumasisitimu ekudzora mvura, inopa yakavimbika uye inoshanda kuyerera kuyerera. Musimboti wavo wekushanda wakapfava asi unoshanda, wakasanganiswa nemabhenefiti ePVC neUPVC zvinhu, unovaita sarudzo yakakurumbira kune dzakasiyana siyana dzekushandisa mumaindasitiri akadai sekuchenesa mvura, kugadzirisa makemikari, uye masystem eHVAC.
