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

Zvinhu izvi zvinozivikanwa nekusimba kwazvo, kuramba kwemakemikari, uye kugona, zvichiita kuti ive sarudzo dzakakurumbira kune dzakasiyana siyana maindasitiri nekugara. Diaphragm mavharuvhu, kunyanya, zvinhu zvakakosha mumasisitimu mazhinji ekudzora mvura, uye kunzwisisa misimboti kuseri kwePVC diaphragm mavharuvhu kunogona kupa ruzivo rwakakosha mukushanda kwavo nemashandisirwo.

Nheyo yePVC diaphragm valve iri mukugadzirwa kwayo, iyo ine diaphragm inoshanduka yakamisikidzwa kudzora kuyerera kwemvura mukati mevharuvhu. Kana vharuvhu iri munzvimbo yakavharwa, diaphragm inovhara pakatarisana nemuviri wevhavha, ichidzivirira kuyerera kwemvura. Kana vharuvhu yakavhurika, diaphragm inochinjika kure nemuviri wevharuvhu, ichibvumira mvura kuti ipfuure. Iyi nzira iri nyore asi inoshanda inoita mavharuvhu ePVC diaphragm akakodzera kudzora kuyerera kwezvinwiwa zvakasiyana siyana, zvinosanganisira zvinoparadza uye zvinokuvadza.

Iko kushandiswa kwePVC uye UPVC mune diaphragm valve fittings inopa akawanda mabhenefiti. Zvinhu izvi zvinoshingirira mukuora, zvichiita kuti zvive zvakanaka pakubata makemikari ane hasha nemaasidhi. Pamusoro pezvo, mavharuvhu ePVC neUPVC akareruka uye ari nyore kuisa, achidzikisa mutengo wevashandi nekugadzirisa. Nzvimbo dzadzo dzemukati dzakatsetseka zvakare dzinoderedza kukweshera kwemvura, zvichikonzera kudzora kuyerera kwakanaka uye kuderedza kushandiswa kwesimba.

Uyezve, PVC uye UPVC valve fittings inowanikwa muhukuru hwakasiyana-siyana uye zvigadziriso, zvichiita kuti zvive zvakakodzera kushandiswa kwakasiyana-siyana mumaindasitiri akadai sekuchenesa mvura, kushandiswa kwemakemikari, uye masisitimu ekudiridza. Kuita kwavo kwakasiyana-siyana uye kudhura-kushanda kwakabatsira mukugamuchirwa kwavo kwakapararira mumaindasitiri nedzimba dzekugara.

Mukupedzisa, musimboti wePVC diaphragm mavharuvhu, akasanganiswa nekushandiswa kwePVC uye UPVC zvinhu, inosimbisa kukosha kwezvikamu izvi mumagetsi ekudzora masisitimu. Kuita kwavo kwakavimbika, kuramba kwemakemikari, uye kuita-mutengo kunoita kuti zvive zvakakosha pakushandisa kwakasiyana-siyana, uye kuenderera mberi kwavo kusimudzira uye hunyanzvi huchawedzera kugona kwavo mune ramangwana.
