Nheyo yePVC cheki vharafu uye kukosha kwayo mupurasitiki yekukodzera valve

PVC (polyvinyl chloride) uye UPVC (unplasticized polyvin) anoshandiswa zvakanyanya mukugadzira mavharuvhu epurasitiki nekuda kwekusimba kwazvo, kuramba kwemakemikari, uye kukwanisa kutenga. Zvinhu izvi zvinowanzoshandiswa mumaindasitiri akasiyana-siyana, kusanganisira kurapwa kwemvura, kudiridza, uye pombi dzemvura. Chimwe chinhu chakakosha chepurasitiki mavharuvhu fittings ndeye PVC cheki vharafu, inoita basa rakakosha mukudzora kuyerera kwemvura uye kudzivirira kuyerera.

Nheyo yePVC cheki vharafu yakavakirwa pane yakapusa asi inoshanda michina. Iyo ine hinged flap kana swinging disc inobvumira fluid kuyerera munzira imwe ichidzivirira kutenderera kuyerera. Apo mvura inoyerera ichienda kwainoda, kudzvinyirirwa kwemvura kunosimudza jira, kuchibvumira kuti ipfuure nepakati pevharuvhu. Zvisinei, kana kuyerera kunomira kana kudzoka shure, iyo flap inovhara pasi pehuremu hwayo, ichidzivirira chero kudzokera shure. Iyi meshini inovimbisa kuti iyo fluid inongofamba munzira yakatarwa, kuchengetedza kushanda uye kuchengetedzwa kwehurongwa.

Kukosha kwePVC cheki mavharuvhu mumidziyo yepurasitiki yevharuvhu haigone kuwedzeredzwa. Vanobatsira mukudzivirira kusvibiswa kwemvura yakachena nekudzokera shure kwemvura yakasvibiswa, kuve nechokwadi chekuchena kwemvura. Muzvirongwa zvekudiridza, PVC cheki mavharuvhu anobatsira kuchengetedza kudzvinyirirwa uye kuyerera kwemvura, kudzivirira kukuvadzwa kwegadziriro uye kuve nechokwadi chekugovera mvura kwakanyatsonaka. Mumapombi emvura, mavharuvhu aya anodzivirira kudzoreredzwa kwetsvina kana tsvina yemvura, kuderedza njodzi yekuvhara uye kuchengetedza hutsanana hwehurongwa.

Uyezve, PVC cheki mavharuvhu ari nyore kuisa uye anoda kushoma kugadziridzwa, zvichiita kuti ive inodhura-inoshanda mhinduro kune akasiyana maapplication. Kuenderana kwavo nePVC uye UPVC zvinhu zvinovaita sarudzo yakanaka yepurasitiki mavharuvhu fittings, kuve nechokwadi chisina musono uye yakavimbika kuyerera kuyerera system.

Mukupedzisa, musimboti wePVC cheki vharafu chinhu chakakosha chepurasitiki mavharuvhu fittings, ichiita basa rakakosha mukudzora kuyerera kwemvura uye kudzivirira kudzoka. Nekushandiswa kwakapararira kwePVC uye UPVC zvinhu mumaindasitiri akasiyana, kukosha kwePVC cheki mavharuvhu hakugone kufuratirwa. Muchina wavo wakapfava asi unoshanda, wakabatanidzwa nekusimba kwavo uye kuderera kwekugadzirisa zvinodiwa, zvinovaita chinhu chakakosha mumidziyo yepurasitiki mavharuvhu.
