Unofanira kutenga mavharuvhu ePVC epurojekiti, asi katarogu yacho inonetsa. Bhora, cheki, shavishavi, diaphragm—kusarudza isiriyo zvinoreva sisitimu inodonha, inokundikana, kana kuti isingashande nemazvo.
Mhando huru dzemavharuvhu ePVC dzinorongwa zvichienderana nebasa radzo: mavharuvhu ebhora ekudzora anobatidza/adzima, mavharuvhu ekutarisa kudzivirira kudzokera shure, mavharuvhu ebhururu ekudzivirira kupwanya mapaipi makuru, uye mavharuvhu ediaphragm ekubata mvura inoparadza kana yehutsanana.
Uyu mubvunzo wandinowanzo kurukura nevamwe vangu, kusanganisira Budi, maneja wepamusoro wekutenga muIndonesia. Vatengi vake, kubva kune vanogadzira makontrakita kusvika kune vatengesi, vanofanirwa kuziva kuti vari kuwana chishandiso chakakodzera chebasa racho.sisitimu yepombiyakasimba chete sechikamu chayo chisina kusimba, uye kusarudza chakakodzerarudzi rwevharuvhundiyo nhanho yekutanga yekuvaka hurongwa hwakavimbika uye hunogara kwenguva refu. Kunzwisisa misiyano iyi hakusi ruzivo rwehunyanzvi chete; ndiyo hwaro hwepurojekiti inobudirira.
Kune mhando dzakasiyana dzemavharuvhu ePCV here?
Unonzwa izwi rekuti "vharuvhu yePVC" uye ungafunga kuti chigadzirwa chimwe chete, chakajairika. Kufungidzira uku kunogona kuita kuti uise vharuvhu isingakwanise kubata kumanikidzwa kana kuita basa raunoda.
Ehe, kune mhando dzakawanda dzemavharuvhu ePVC, rimwe nerimwe rine nzira yaro yemukati yakagadzirirwa basa rakati. Anonyanya kushandiswa ndeekutanga/kumisa kuyerera kwemvura (mavharuvhu ebhora) uye kudzivirira otomatiki kuyerera kwemvura (tarisa mavharuvhu).
Kufunga kuti mavharuvhu ese ePVC akafanana chikanganiso chinowanzoitika. Muchokwadi, chikamu che "PVC" chinongotsanangura zvinhu zvinogadzirwa nevharuvhu—purasitiki yakasimba, inodzivirira ngura. Chikamu che "vharuvhu" chinotsanangura basa rayo. Kuti tibatsire Budi nechikwata chake kutungamira vatengi vavo, tinovatsanangura nebasa ravo guru. Kupatsanura uku kuri nyore kunobatsira munhu wese kusarudza chigadzirwa chakakodzera nekuvimba.
Heino kupatsanurwa kwakakosha kwemhando dzakajairika dzauchasangana nadzo mukutarisira mvura:
| Rudzi rweVharuvhu | Basa Guru | Nyaya Inoshandiswa Kazhinji |
|---|---|---|
| Vharuvhu yeBhora | Kudzora Kushanda/Kudzima | Mitsetse mikuru yemvura, michina yekuparadzanisa, nzvimbo dzekudiridza |
| Vharuvhu Yekutarisa | Dzivisa Kudzokera Kwemvura | Pombi dzinobuda, dzinodzivirira kudzoka kwemvura inoyerera, dzinodzivirira mamita emvura |
| Vharuvhu yeBhatafurayi | Kurovera/Kubatidza/Kudzima | Mapaipi makuru (3″ zvichikwira), nzvimbo dzekuchenesa mvura |
| Vharuvhu yeDiaphragm | Kurovera/Kubatidza/Kudzima | Makemikari anoparadza, kushandiswa kwehutsanana, slurry |
Ndeapi marudzi mana ePVC?
Unoona mavara akasiyana-siyana akadai sePVC-U neC-PVC wobva washamisika kana aine basa nazvo. Kushandisa vharuvhu yakajairwa mumutsara wemvura inopisa nekuti waisaziva musiyano wacho kunogona kukonzera kutadza kushanda zvakanaka.
Mubvunzo uyu uri pamusoro pepurasitiki, kwete rudzi rwevharuvhu. Zvinhu zvina zvakajairika zvePVC-family ndeizvi: PVC-U (yakajairwa, yemvura inotonhora), C-PVC (yemvura inopisa), PVC-O (yakasimba kwazvo), uye M-PVC (yakagadziriswa).
Uyu mubvunzo wakanaka nekuti unosvika pamwoyo wemhando yechigadzirwa uye kuchengetedzeka kwekushandiswa. Kuvhiringidza mhando dzemavharuvhu nemhando dzezvinhu zviri nyore. KuPntek, tinotenda kuti mubatsiri akadzidza mubatsiri anobudirira, saka kujekesa izvi kwakakosha. Zvinhu zvakagadzirwa nevharuvhu yako zvinotema miganhu yekupisa kwayo, chiyero chekumanikidzwa, uye kuramba kwemakemikari.
PVC-U (Polyvinyl Chloride Isina Kugadzirwa nepurasitiki)
Iyi ndiyo mhando yePVC inonyanya kushandiswa pakuisa mapaipi, mafitting, uye mavharuvhu kuNorth America, Europe, neAsia. Yakasimba, inodhura zvishoma, uye inodzivirira zvakanyanya kumakemikari akasiyana-siyana. Ndiyo nzira inoshandiswa mumvura inotonhora. Mazhinji emavharuvhu edu ePntek ball uye check valves ayo Budi anoraira akagadzirwa nePVC-U yepamusoro.
C-PVC (Chlorinated Polyvinyl Chloride)
C-PVC inopfuura nekuwedzera chlorination process. Kuchinja kuri nyore uku kunowedzera zvakanyanya kuramba kwayo tembiricha. Kunyange hazvo PVC-U ichingofanira kushandiswa kusvika 60°C (140°F), C-PVC inogona kubata tembiricha inosvika 93°C (200°F). Unofanira kushandisa mavharuvhu eC-PVC pamigero yemvura inopisa.
Mamwe Marudzi
PVC-O (Oriented) neM-PVC (Modified) hazviwanzo kuwanikwa mumavharuvhu asi zvinonyanya kuwanikwa pamapombi epressure akasarudzika, asi zvakanaka kuziva kuti aripo. Akagadzirwa kuti awedzere kumanikidzwa uye ave nesimba rekubata.
Ndeapi marudzi matanhatu makuru emavharuvhu?
Uri kuvaka sisitimu yakaoma uye unoda zvinopfuura kungoshandisa vharuvhu yekudzima nekudzima chete. Kuona mazita akadai sekuti “Globe” kana kuti “Gate” kunogona kuvhiringidza kana uchishanda nemavharuvhu ebhora ePVC.
Mhuri nhanhatu huru dzemavharuvhu dzinoshanda zvakanaka ndedzeBall, Gate, Globe, Check, Butterfly, uye Diaphragm. Mazhinji acho anowanikwa muPVC kuti ashandiswe kana mavharuvhu esimbi achizoora kana kuti achidhura zvakanyanya.
Kunyange zvazvo tichitarisa pamhando dzePVC dzinonyanya kushandiswa, kunzwisisa mhuri yese yemavharuvhu kunokubatsira kuziva kuti nei mamwe mavharuvhu achisarudzwa pane mamwe. Mamwe ndiwo maitiro eindasitiri, nepo mamwe ari emabasa chaiwo. Ruzivo urwu rwakakura runobatsira timu yaBudi kupindura kunyangwe mibvunzo yevatengi yakadzama.
| Mhuri yeValve | Mashandiro Azvo | Zvakajairika muPVC? |
|---|---|---|
| Vharuvhu yeBhora | Bhora rine gomba rinotenderera kuti rivhurike/rivhare. | Zvakajairika.Yakakwana pakugadzirisa nekudzima. |
| Vharuvhu yeGedhi | Gedhi rakati sandara rinotsvedza richikwira nekudzika kuti rivhare kuyerera kwemvura. | Hazviwanzoitiki. Kazhinji zvinotsiviwa nemavharuvhu ebhora akavimbika. |
| Vharuvhu Yepasi | Puragi inofamba ichitenderedza chigaro kuti idzore kuyerera kwemvura. | Nzvimbo Yakakodzera. Inoshandiswa pakupinza madziro nemazvo, asi haiwanzoitiki paPVC. |

Ndeapi marudzi akasiyana emavharuvhu ekuongorora ePVC?
Unoda vharuvhu rekutarisa kuti mvura isadzokere shure, asi unoona sarudzo dzakadai sekuti “swing,” “ball,” uye “spring.” Kuisa risiri iro kunogona kukonzera kutadza kushanda, hammer yemvura, kana kuti vharuvhu isashande zvachose.
Mhando huru dzemavharuvhu ekuongorora ePVC ndedzekutarisa kweswing, kutarisa bhora, uye kutarisa kwechitubu. Imwe neimwe inoshandisa nzira yakasiyana yekumisa kuyerera kwemashure uye yakakodzera marongero akasiyana epombi nemamiriro ekuyerera.
Vharuvhu yekucheki ndiyo inochengetedza sisitimu yako, inoshanda yega isina mibato kana simba rekunze. Asi havasi vese vanochengetedza vanoshanda nenzira imwechete. Kusarudza chaiyo kwakakosha pakudzivirira pombi uye kusimba kwesisitimu. Ichi chinhu chandinogara ndichisimbisa naBudi, sezvo chinokanganisa zvakananga kuvimbika kwenguva refu kwekuisa kwevatengi vake.
Vharuvhu yekutarisa yePVC Swing
Iyi ndiyo mhando iri nyore. Ine hinged flap (kana disc) inovhurika nekuyerera kwemvura. Kana kuyerera kwacho kwamira kana kudzokera shure, simba rinokwevera pasi nekumanikidzwa kwemusana zvinotenderedza flap yacho pachigaro chayo. Inoshanda zvakanaka mumapaipi akatwasuka kana mumapaipi akamira ane kuyerera kumusoro.
Vharuvhu yekutarisa bhora rePVC
Iyi ndiyo hunyanzvi hwedu kuPntek. Bhora rakatenderera rinogara mukamuri. Kuyerera kwemberi kunosunda bhora kubva munzira yekuyerera. Kana kuyerera kwadzoka shure, kunosundira bhora kumashure muchigaro, zvichiita kuti rive rakanyatsosimba. Rakavimbika zvikuru, rinogona kuiswa rakamira kana kuti rakatwasuka, uye harina mahinji kana masprings ekusakara.
PVC Spring Check Valve
Rudzi urwu runoshandisa chitubu kuti chibatsire kuvhara vharuvhu nekukurumidza kana mvura yamira. Kuvhara uku nekukurumidza kwakanaka pakudzivirira mvura inodonha—mafungu anokuvadza anokonzerwa nekumira kamwe kamwe kwemvura. Anogona kuiswa chero kwaakananga.
Mhedziso
Kusarudza vharuvhu chaiyo yePVC zvinoreva kunzwisisa rudzi rwayo—bhora rekutonga, kutarisa kana ichidzokera shure—uye purasitiki pachayo. Ruzivo urwu runovimbisa kuvimbika kwesystem, runodzivirira kutadza kushanda, uye runovaka kuvimba kwevatengi.
