Uri kuyedza kuodha mavharuvhu, asi mumwe mutengesi anoadaidza kuti PVC uye mumwe anodaidza iwo UPVC. Iyi nyonganiso inoita kuti uzvinetse kuti uri kuenzanisa zvigadzirwa zvakasiyana kana kutenga zvisirizvo zvinhu.
Kune mavharuvhu akaomarara, hapana musiyano unoshanda pakati pePVC neUPVC. Mazwi ese ari maviri anoreva zvakafananaunplasticized polyvinyl chloride zvinhu, iyo yakasimba, isingadziviriri, uye yakanakira zvirongwa zvemvura.
Uyu ndiwo mumwe wemibvunzo yakajairika yandinowana, uye inokonzeresa nyonganiso isingakoshi muchikamu chekugovera. Nguva pfupi yadarika ndanga ndichitaura naBudi, maneja wekutenga kubva kune mumwe muparidzi mukuru muIndonesia. Vatengi vake vadiki vadiki vaive vamira, vachifunga kuti vaifanira kuburitsa marudzi maviri akasiyana emavharuvhu. Ndakamutsanangurira kuti kune mavharuvhu akaoma atinogadzira paPntek, uye kune akawanda emabhizimisi, mazita anoshandiswa zvakasiyana. Kunzwisisa chikonzero nei kuchizokupa chivimbo mumasarudzo ako ekutenga.
Pane musiyano pakati pePVC neUPVC?
Iwe unoona maviri akasiyana acronyms uye nemaitiro anofungidzira anomiririra maviri akasiyana zvinhu. Kusahadzika uku kunogona kudzikisira mapurojekiti ako paunenge uchiedza kuona zvakatemwa.
Chaizvoizvo, kwete. Muchirevo chepombi dzakaoma uye mavharuvhu, PVC uye UPVC zvakafanana. Iyo "U" muUPVC inomirira "unplasticized," inotova chokwadi kune ese akaomarara PVC mavharuvhu.
Kuvhiringidzika kunobva munhoroondo yemapurasitiki. Polyvinyl chloride (PVC) ndiyo nheyo yezvinhu. Kuita kuti ikwanise kuchinjika kune zvigadzirwa senge hosi dzegadheni kana magetsi ekudzivirira waya, vagadziri vanowedzera zvinhu zvinonzi plasticizers. Kuti tisiyanise fomu rekutanga, rakaomarara kubva kushanduro inoshanduka, izwi rekuti "isina purasitiki" kana "UPVC" rakabuda. Nekudaro, kune maapplication akaita seakamanikidzwa mvura masisitimu, haungambo shandisa iyo inoshanduka vhezheni. Mapaipi ese akaomarara ePVC, mafittings, uye mavharuvhu ebhora, nehunhu hwawo, haana purasitiki. Saka, nepo mamwe makambani achidaidza zvigadzirwa zvawo kuti "UPVC" kuti zvive zvakanyatsojeka, uye mamwe achingoshandisa iyo yakajairika "PVC," ivo vari kureva iyo chaiyo yakasimba, yakaoma zvinhu. PaPntek, tinovadaidza chetePVC bhora mavharuvhunekuti ndiro izwi rinowanzozivikanwa, asi ese ari tekinoroji UPVC.
Mavharuvhu ebhora ePVC akanaka here?
Iwe unoona kuti PVC ipurasitiki uye inodhura zvishoma pane simbi. Izvi zvinokuita kuti ubvunze hunhu hwayo uye kushamisika kana yakasimba zvakakwana kune yako yakakomba, yenguva refu yekushandisa.
Ehe, emhando yepamusoro PVC bhora mavharuvhu akanakisa kune chinangwa chavanoda. Iwo haadzivirirwe kune ngura uye ngura, akareruka, uye anopa hupenyu hurefu hwesevhisi mumashandisirwo emvura inotonhora, kazhinji achipfuura mavharuvhu esimbi.
Kukosha kwavo hakusi mumutengo wavo wakaderera chete; zviri mukuita kwavo munzvimbo chaidzo. Mavharuvhu esimbi, sendarira kana simbi, anosakara kana kupera nekufamba kwenguva, kunyanya mumasisitimu ane mvura yakabikwa, mvura yemunyu, kana mamwe makemikari. Kuora uku kunogona kuita kuti vharuvhu itore kumusoro, zvichiita kuti zvisaite kutendeuka mune emergency. PVC haigoni kuita ngura. Ikemikari inert kune akawanda ekuwedzera emvura, munyu, uye mild acids. Ichi ndicho chikonzero vatengi veBudi muindasitiri yemahombekombe egungwa muIndonesia vachishandisa mavharuvhu ePVC chete. Mvura yemunyu yaizoparadza mavharuvhu esimbi mumakore mashoma, asi mavharuvhu edu ePVC anoramba achishanda zvakanaka kwemakore gumi kana kupfuura. Kune chero application iri pasi pe60°C (140°F), aPVC bhora vharafuhaisiriyo “yakachipa” sarudzo; kazhinji isarudzo yakavimbika uye inogara kwenguva refu nekuti haife yakabata kubva mukuora.
Ndeipi yakanakisa mhando yevharuvhu yebhora?
Iwe unoda kutenga "yakanakisa" valve kuti uone kuti system yako yakavimbika. Asi nezvakawanda zvezvinhu zviripo, kusarudza iyo yakanyanya kunaka inonzwa ichirema uye ine njodzi.
Iko hakuna imwechete "yakanakisa" bhora vharafu yebasa rega rega. Iyo yakanakisa vharafu ndiyo ine zvinhu uye dhizaini yakanyatsoenderana nekushisa kwesystem yako, kudzvanywa, uye makemikari nharaunda.
"Zvakanakisa" zvinogara zvine chekuita nekushandisa. Kusarudza isina kururama kwakafanana nokushandisa motokari yemitambo kutakura matombo—chishandiso chisiricho chebasa racho. A Stainless simbi vharafu yakanakira tembiricha yakakwira uye kumanikidza, asi inodhura yakawandisa kune dziva rekutenderera system, uko PVC vharafu iri pamusoro nekuda kweiyochlorine kuramba. Ndinogara ndichitungamira vamwe vangu kuti vafunge nezve chaiwo mamiriro eprojekiti yavo. A PVC vharafu ndiyo shasha yemasisitimu emvura inotonhora nekuda kwekupokana kwayo uye mutengo. Pamvura inopisa, unofanirwa kukwira kusvikaCPVC. Kune yakakwira-kumanikidza gasi kana mafuta, ndarira itsika, yakavimbika sarudzo. Pakushandiswa kwegiredhi rekudya kana makemikari anoparadza zvakanyanya, simbi isina tsvina inowanzodiwa. Sarudzo yechokwadi "yakanakisa" ndiyo inopa kuchengetedzwa kunodiwa uye hupenyu hurefu hwemutengo wakaderera wakazara.
Ball Valve Material Guide
| Material | Best For | Temperature Limit | Kubatsira Kwakakosha |
|---|---|---|---|
| PVC | Mvura Inotonhora, Madziva, Kudiridza, Aquariums | ~60°C (140°F) | Haisi kuzoora, inokwanisika. |
| CPVC | Mvura Inopisa uye Inotonhora, Mild Industrial | ~90°C (200°F) | Higher kupisa kuramba kupfuura PVC. |
| Brass | Plumbing, Gasi, High Pressure | ~120°C (250°F) | Yakasimba, yakanaka kune yakakwirira-kudzvanywa zvisimbiso. |
| Simbi isina ngura | Chikafu Chekudya, Makemikari, High Temp / Pressure | >200°C (400°F) | Kusimba kwepamusoro uye kusagadzikana kwemakemikari. |
Ndeupi musiyano uripo pakati pePVC U neUPVC?
Pawaifunga kuti wanzwisisa PVC vs. UPVC, unoona "PVC-U" pagwaro rehunyanzvi. Iri izwi idzva rinowedzera imwe nhanho yekuvhiringidzika, zvichiita kuti iwe wechipiri-fembera kunzwisisa kwako.
Hapana mutsauko zvachose. PVC-U ingori imwe nzira yekunyora uPVC. Iyo "-U" inomirirawo unplasticized. Iri gungano rezita rinowanzoonekwa muEuropean kana pasi rose zviyero (seDIN kana ISO).
Funga nezvazvo sekutaura "madhora zana" maringe ne "100 mari." Iwo mazwi akasiyana echinhu chimwe chete. Munyika yemapurasitiki, matunhu akasiyana akagadzira nzira dzakasiyana siyana dzekuti zvinhu izvi. KuNorth America, "PVC" ndiro izwi rinowanzoreva pombi yakaoma, uye "UPVC" dzimwe nguva inoshandiswa kujekesa. MuEurope uye pasi pezviyero zvepasi rose, "PVC-U" ndiyo inonyanya kurongeka izwi reinjiniya kutsanangura "isina purasitiki." Kune mutengi saBudi, ichi chikamu chakakosha cheruzivo kuchikwata chake. Pavanoona nyoro yeEurope inotsanangura mavharuvhu ePVC-U, vanoziva nechivimbo kuti mavharuvhu edu ePVC anoenderana nezvinodiwa zvakakwana. Izvo zvese zvinodzika kune chinhu chimwe chete: yakasimba, yakasimba, isina purasitiki vinyl polymer iyo yakanakira mavharuvhu ebhora. Usabatwa netsamba; tarisa pazvinhu zvechinyorwa uye maitiro ekuita.
Mhedziso
PVC, UPVC, uye PVC-U ese anoreva kune imwechete yakaomarara, isina plastiki chinhu chakanakira mvura inotonhora mavharuvhu ebhora. Misiyano yemazita ingori kokorodzano dzematunhu kana nhoroondo.
