PVC Tarisa Valve Nheyo iyo Basics

PVC (polyvinyl chloride) uye UPVC (unplasticized polyvinyl chloride) zvinhu zvinoshandiswa zvakanyanya mukugadzira mavharuvhu nekuisa. Zvishandiso izvi zvinozivikanwa nekusimba kwazvo, kusamira kwemakemikari, uye kugona, zvichiita kuti ive sarudzo dzakakurumbira kune dzakasiyana siyana dzekushandisa, kusanganisira pombi dzemvura, kudiridza, uye maindasitiri maitiro.

Chimwe chezvinhu zvakakosha muPVC kana UPVC pombi system ndeye cheki vharuvhu. Rudzi urwu rwevharuvhu rwakagadzirirwa kubvumira mvura kuyerera munzira imwe ichidzivirira kutenderera kuyerera. Kunzwisisa musimboti uri kuseri kwePVC cheki mavharuvhu uye mafittings awo kwakakosha kuti uve nechokwadi chekushanda kwakanaka kwepombi system.

Nheyo yePVC cheki valve iri nyore. Iyo ine muviri wevharuvhu ine inlet uye yekubuda, uye inofambiswa michina, senge bhora, disc, kana diaphragm, inobvumira kuyerera kune imwe nzira uchiivharira kune yakatarisana. Kana mvura ichiyerera nenzira kwayo, mashandiro anovhura, achibvumira kuti mvura ipfuure. Zvisinei, kana kuyerera kuchidzokera shure, iyo nzira inovhara, ichidzivirira kudzokera shure.

Pamusoro pevhavha pachayo, zvigadziriso zvinoshandiswa pamwe chete nePVC cheki mavharuvhu anoita basa rakakosha mukuita kwese kwehurongwa. Zvishongedzo zvakadai sekubatanidza, magokora, uye tee zvinoshandiswa kubatanidza cheki valve kune pombi system uye kuona kurongeka kwakakodzera uye kutsigirwa. Izvo zvakakosha kuti usarudze mafittings anoenderana nePVC kana UPVC zvinhu uye akagadzirirwa kutsungirira kumanikidza uye kuyerera mamiriro ehurongwa.

Paunosarudza PVC kana UPVC cheki mavharuvhu uye mafittings, zvakakosha kuti utarise izvo chaizvo zvinodiwa zvekushandisa. Zvinhu zvakadai semhando yemvura iri kufambiswa, kudzvanywa kwekushanda uye tembiricha, uye mwero wekuyerera zvinokanganisa kusarudzwa kwevharuvhu yakakodzera uye mafittings. Pamusoro pezvo, zvakakosha kuve nechokwadi chekuti zvikamu zvinosangana neindasitiri zviyero uye mirau kuvimbisa kuchengetedzeka uye kuvimbika kweiyo system.

Kuiswa kwePVC cheki mavharuvhu uye zvigadziriso zvinofanirwa kuitwa nemazvo uye nehanya kudzivirira chero zvingangoitika. Kurongeka kwakakodzera, kubatana kwakachengeteka, uye kutsigirwa kwakakwana kwakakosha pakushanda kwakanaka kwehurongwa. Izvo zvakakoshawo kutevedzera nhungamiro yemugadziri uye kurudziro yekumisikidza, kusanganisira kushandiswa kweanoenderana sealants uye adhesives.

Kugara uchigadzirisa uye kuongororwa kwePVC cheki mavharuvhu uye mafittings kwakakosha pakuona uye kugadzirisa chero zvingangoitika. Izvi zvinosanganisira kutarisa zviratidzo zvekusakara, ngura, kana kukuvadzwa, pamwe nekuona kuti mavharuvhu ari kushanda nemazvo uye kuvhara zvakanaka. Chero zvinhu zvakasakara kana kukuvadzwa zvinofanirwa kutsiviwa nekukasira kudzivirira kutadza kwehurongwa uye kudonha.

Mukupedzisa, musimboti wePVC cheki mavharuvhu uye fittings yakavakirwa pakukwanisa kudzora kuyerera kwemvura mupombi system. Kunzwisisa kushanda uye kusarudzwa kwakakodzera kwezvikamu izvi zvakakosha pakushanda kwakanaka uye kwakavimbika kwepombi dzemvura, kudiridza, uye maindasitiri masisitimu. Nekuomerera kune indasitiri zviyero uye akanakisa maitiro, PVC uye UPVC cheki mavharuvhu uye zvigadziriso zvinogona kupa kushanda kwenguva refu uye kubatsira mukushanda kwese kwepombi system.
