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

Zvishandiso izvi zvinozivikanwa nekusimba kwazvo, corrosion resistance, uye kukwanisa kutenga, zvichiita kuti ive sarudzo dzakakurumbira kune dzakasiyana siyana dzekushandisa. Imwe mhando yevharuvhu inokwana iyo inowanzo gadzirwa kubva kuPVC kana UPVC ivhavhavhavhavhavha.

Nheyo yePVC butterfly valve yakavakirwa padhizaini iri nyore asi inoshanda. Ivhavha inoumbwa ne diski, iyo yakasungirirwa pane shaft inotenderera. Kana iyo valve iri munzvimbo yakavharwa, iyo disc inotenderera kune kuyerera kwemvura, inonyatso kuivharira. Kana vharuvhu yakavhurwa, dhisiki inotenderera yakaenzana nekuyerera, ichibvumira mvura kuti ipfuure.

Kushandiswa kwePVC kana UPVC mukuvaka mavharuvhu e butterfly kunopa zvakati wandei zvakanakira. Zvinhu izvi zvakareruka, zvichiita kuti mavharuvhu ave nyore kubata nekuisa. Izvo zvakare zvinopesana nekuora, zvichiita kuti zvikodzere kushandiswa munzvimbo dzakasiyana siyana, kusanganisira idzo dzinosangana nemakemikari kana mamiriro ekunze akaomarara. Pamusoro pezvo, PVC neUPVC haina chepfu uye yakachengeteka kuti ishandiswe mumashandisirwo anosanganisira mvura inonwiwa kana kugadzira chikafu.

Iyo yakatsetseka yemukati mepamusoro yePVC uye UPVC butterfly mavharuvhu inoderedza kuyerera kwekudzivirira, kuderedza kudonha kwekumanikidza uye kushandiswa kwesimba. Izvi zvinovaita sarudzo inoshanda yekudzora kuyerera kwemvura muhurongwa. Uyezve, zvinhu izvi zvigadziriso zvakaderera, zvinoda kuchengetwa zvishoma pamusoro pehupenyu hwavo.

PVC uye UPVC butterfly mavharuvhu anowanzo shandiswa mumaindasitiri akadai sekuchenesa mvura, kudiridza, kugadzira makemikari, uye HVAC masisitimu. Kuita kwavo kwakasiyana-siyana uye kudhura-kushanda kunoita kuti vave sarudzo yakakurumbira yekudzora kuyerera kwemvura, mhepo, uye zvimwe zvinwiwa mune zvakasiyana-siyana zvekushandisa.

Mukupedzisa, musimboti wePVC butterfly valve unobva pakutenderera kwedisiki kudzora kuyerera kwemvura. Kushandiswa kwePVC uye UPVC zvinhu mukuvaka mavharuvhu aya kunopa akawanda mabhenefiti, anosanganisira kusimba, kusaita ngura, uye kushanda nesimba. Unhu uhwu hunoita kuti PVC neUPVC butterfly mavharuvhu ave akavimbika uye anodhura-mhinduro yekugadzirisa mvura munzvimbo dzakasiyana siyana dzeindasitiri neyekutengesa.
