Iwe unofanirwa kutenga mavharuvhu ePVC epurojekiti, asi iyo catalog inorema. Bhora, cheki, shavishavi, diaphragm — kusarudza isina kururama kunoreva gadziriro inobvinza, inokundikana, kana kuti isingashande zvakanaka.

Mhando huru dzemavharuvhu ePVC dzakakamurwa nebasa radzo: mavharuvhu ebhora ekuti on/off control, tarisa mavharuvhu ekudzivirira kubuda shure, mavharuvhu eshavishavi ekukwenya pombi hombe, uye mavharuvhu ediaphragm ekubata mvura inoparadza kana yehutsanana.

Uyu mubvunzo wandinogara ndichikurukura nevandinoshanda navo, kusanganisira Budi, maneja wepamusoro wekutenga muIndonesia. Vatengi vake, kubva kumakondirakiti kusvika kune vatengesi, vanofanirwa kuziva kuti vari kuwana chishandiso chakakodzera chebasa racho. Apombi systeminongosimba sechikamu chayo chisina kusimba, uye kusarudza iyo chaiyorudzi rwevharuvhundiro danho rokutanga pakuvaka gadziriro yakavimbika, inogara kwenguva refu. Kunzwisisa misiyano iyi haingori ruzivo rwehunyanzvi; ndiyo hwaro hwechirongwa chakabudirira.

Kune marudzi akasiyana ePCV mavharuvhu here?

Iwe unonzwa izwi rekuti "PVC vharafu" uye unogona kufunga kuti chinhu chimwe chete, chakajairwa chigadzirwa. Iyi fungidziro inogona kukutungamira iwe kuti uise vharafu isingakwanise kubata kumanikidza kana kuita basa raunoda.

Hongu, kune akawanda marudzi ePVC mavharuvhu, imwe neimwe ine yakasarudzika yemukati meshini yakagadzirirwa basa rakati. Inonyanya kuzivikanwa ndeyekutanga / kumisa kuyerera (mavharuvhu ebhora) uye otomatiki kudzivirira reverse kuyerera (tarisa mavharuvhu).

Kufunga kuti mavharuvhu ese ePVC akafanana kukanganisa kwakajairika. Muchokwadi, chikamu che "PVC" chinongotsanangura zvinhu izvo vharafu inogadzirwa kubva-inogara yakasimba, isingaiti ngura. Chikamu che "vharuvhu" chinotsanangura basa rayo. Kubatsira Budi nechikwata chake kutungamira vatengi vavo, tinovatyora nebasa ravo rekutanga. Iyi kupatsanurwa kwakapfava kunobatsira munhu wese kusarudza chigadzirwa chakakodzera nechivimbo.

Heino kupatsanurwa kwekutanga kwemhando dzakajairika dzauchasangana nazvo mukutarisira mvura:

Ndeapi marudzi mana ePVC?

Iwe unoona mavara akasiyana sePVC-U uye C-PVC uye unoshamisika kana ane basa. Kushandisa vheji yakajairika mumutsetse wemvura inopisa nekuti wanga usingazivi mutsauko unogona kukonzera kutadza kukuru.

Uyu mubvunzo uri pamusoro pezvinhu zvepurasitiki, kwete rudzi rwevharuvhu. Izvo zvina zvakajairika zvePVC-mhuri zvinhu PVC-U (yakajairwa, yemvura inotonhora), C-PVC (yemvura inopisa), PVC-O (yakakwirira-simba), uye M-PVC (impact-modified).

Uyu mubvunzo unonakidza nekuti unosvika pamwoyo wemhando yechigadzirwa uye kuchengetedza kwekushandisa. kuvhiringa mhando dzevharuvhu nemhando yezvinhu zviri nyore. PaPntek, tinotenda kuti mumwe munhu akadzidza mudiwa akabudirira, saka kujekesa izvi kwakakosha. Izvo vharafu yako inogadzirwa kubva kune inoraira tembiricha yayo, chiyero chekumanikidza, uye makemikari kuramba.

PVC-U (Unplasticized Polyvinyl Chloride)

Iyi ndiyo inonyanya kuzivikanwa mhando yePVC inoshandiswa papombi, mafittings, uye mavharuvhu muNorth America, Europe, neAsia. Iyo yakaoma, inodhura-inoshanda, uye inopikisa zvakanyanya kumhando dzakasiyana dzemakemikari. Ndiwo chiyero chekushandisa mvura inotonhora. Mazhinji ePntek mavharuvhu edu ebhora uye cheki mavharuvhu ayo Budi anoodha anogadzirwa kubva kune yepamusoro-giredhi PVC-U.

C-PVC (Chlorinated Polyvinyl Chloride)

C-PVC inopfuura neimwe nzira yekuwedzera chlorination. Kuchinja kuri nyore uku kunowedzera kuwedzera kwekushisa kwayo. Nepo PVC-U ichifanirwa kungoshandiswa kusvika pa60°C (140°F), C-PVC inokwanisa kubata tembiricha inosvika 93°C (200°F). Iwe unofanirwa kushandisa mavharuvhu eC-PVC kumitsetse yemvura inopisa.

Dzimwe Mhando

PVC-O (Oriented) neM-PVC (Yakagadziridzwa) haanyanye kuwanda kumavharuvhu uye akawanda kune akasarudzika pombi dzekumanikidza, asi zvakanaka kuziva kuti aripo. Iwo akagadzirirwa epamusoro kudzvinyirira ratings uye nani simba rekuita.

Ndeapi marudzi makuru matanhatu emavharuvhu?

Iwe uri kuvaka yakaoma sisitimu uye inoda zvinopfuura kungoita nyore pa/kudzima vharafu. Kuona mazita akaita se "Globe" kana "Gedhi" zvinogona kuvhiringa kana iwe uchinyanya kushanda nePVC bhora mavharuvhu.

Mhuri nhanhatu dzinoshanda dzevharuvhu iBhora, Gedhi, Globe, Cheki, Butterfly, uye Diaphragm mavharuvhu. Mazhinji anowanikwa muPVC kubata zvikumbiro apo mavharuvhu esimbi angaora kana kudhura zvakanyanya.

Nepo isu tichitarisa pane akajairika PVC marudzi, kunzwisisa mhuri yese yevharuvhu kunobatsira iwe kuziva kuti nei mamwe mavharuvhu achisarudzwa pane mamwe. Mamwe maindasitiri zviyero, nepo mamwe ari emabasa chaiwo. Iri ruzivo rwakakura runobatsira timu yaBudi kupindura kunyangwe yakadzama mibvunzo yemutengi.

Kune general management yemvura,bhora mavharuvhu, cheki mavharuvhu,uyebutterfly valvesndiyo inonyanya kukosha PVC marudzi kuziva.

Ndeapi marudzi akasiyana ePVC cheki mavharuvhu?

Unoda cheki vharuvhu kudzivirira kuyerera, asi iwe unoona sarudzo senge "swing," "bhora," uye "spring." Kuisa iyo isiriyo kunogona kukonzera kukundikana, sando yemvura, kana vharafu kusashanda zvachose.

Mhando huru dzePVC cheki mavharuvhu is swing cheki, cheki yebhora, uye cheki yechirimo. Imwe neimwe inoshandisa nzira yakasiyana yekumisa reverse kuyerera uye inokodzera kwakasiyana pombi kutaridzika uye kuyerera mamiriro.

Cheki vharuvhu ndiyo inochengetedza sisitimu yako yakanyarara, inoshanda otomatiki isina chero zvibato kana simba rekunze. Asi havasi vese vanochengeta vanoshanda nenzira imwechete. Kusarudza iyo chaiyo yakakosha pakudzivirira kwepombi uye kutendeseka kwehurongwa. Iyi inyaya yandinogara ndichisimbisa naBudi, sezvo ichikanganisa zvakananga kuvimbika kwenguva refu kwekumisikidzwa kwevatengi vake.

PVC Swing Tarisa Valve

Iyi ndiyo mhando yakapfava. Inosanganisira hinged flap (kana disc) inovhurika nekuyerera kwemvura. Kana kuyerera kwamira kana kudzosera kumashure, giravhiti uye kumashure-kudzvanya kunotenderedza bhapa kuvharika pachigaro chayo. Anoshanda zvakanyanya mumapombi akachinjika kana mumapombi akachinjika ane kuyerera kunokwira.

PVC Bhora Tarisa Vvhavha

Uku ndiko hunyanzvi hwedu paPntek. Bhora rakatenderera rinogara mukamuri. Kuyerera kwemberi kunosundira bhora kunze kwenzira yekuyerera. Kana kuyerera kuchidzokera kumashure, inosundidzira bhora kumashure, ichigadzira chisimbiso chakasimba. Iwo akavimbika zvakanyanya, anogona kuiswa akatwasuka kana akachinjika, uye haana hinge kana zvitubu zvekusakara.

PVC Spring Check Valve

Rudzi urwu runoshandisa chitubu kubatsira kuvhara vharafu nekukurumidza kana kuyerera kwamira. Ichi chiito chekuvhara nekukurumidza chakanakira kudzivirira nyundo yemvura-iyo inokuvadza shockwave inogadzirwa nekungoerekana yamira mukuyerera. Vanogona kuiswa mune chero maitiro.

Mhedziso

Kusarudza yakarurama PVC valve kunoreva kunzwisisa rudzi rwayo-bhora rekutonga, tarisa kuti inodzokera shure-uye zvinhu zvepurasitiki pachazvo. Iyi ruzivo inovimbisa kuvimbika kwehurongwa, inodzivirira kutadza, uye inovaka kuvimba kwevatengi.
