Iwe unofanirwa kusarudza vharafu, asi iyo ndarira nePVC sarudzo dzine mibairo mikuru yemutengo. Kusarudza isiriyo kunogona kukonzera ngura, kudonha, kana kushandisa zvakanyanya.
Musiyano mukuru ndeyezvinhu: PVC ipurasitiki yakareruka iyo inodzivirira zvachose kune ngura uye yakanakira mvura inotonhora. Brass inorema, yakasimba simbi alloy inokwanisa kubata tembiricha yakakwira uye kumanikidzwa asi inogona kukora nekufamba kwenguva.
Uyu ndiwo mubvunzo unowanzoitika wandinowana. Ndaingokurukura naBudi, maneja wekutenga wandinoshanda naye kuIndonesia. Anofanira kupa boka rake rekutengesa mhinduro dzakajeka, dzakareruka kune vatengi vavo, vanobva kuvarimi kusvika kune vanogadzira pombi kusvika kune vavaki vedziva. Vamiriri vake vepamusoro havangotengese zvikamu; vanogadzirisa matambudziko. Uye danho rekutanga rekugadzirisa dambudziko kunzwisisa mutsauko wakakosha pakati pezvishandiso. Kana zvasvika kune ndarira maringe nePVC, misiyano yakakura, uye kusarudza iyo chaiyo yakakosha kune yakachengeteka, inogara kwenguva refu sisitimu. Ngatiburitsei chaizvo zvamunoda kuziva.
Ndeipi iri nani ndarira kana PVC bhora mavharuvhu?
Uri kutarisa mavharuvhu maviri, imwe ipurasitiki yakachipa uye imwe simbi inodhura. Iyo simbi inokosha chaizvo mari yakawedzerwa here? Sarudzo isiriyo inogona kuve kukanganisa kunodhura.
Hapana chinhu chiri nani pasi rose. PVC ndiyo sarudzo iri nani yenzvimbo dzinoora uye ese akajairwa mvura inotonhora yekushandisa. Brass iri nani kune tembiricha yakakwira, kumanikidza kwakanyanya, uye kana simba remuviri riri chinhu chakakosha.
Mubvunzo wekuti "zviri nani" nguva dzose unouya kune rimwe basa. Kune vazhinji vevatengi veBudi vari kuvaka mapurazi ezvekurima pamhenderekedzo yegungwa, PVC iri nani. Mhepo ine munyu nemvura yaigona kukanganisa mavharuvhu endarira, zvichiita kuti abate kana kudonha mukati memakore mashoma. YeduPVC mavharuvhuhazvina kukanganiswa zvachose nemunyu uye zvichagara kwemakumi emakore. Nekudaro, kana mutengi ari plumber achiisa hita yemvura inopisa, PVC haisi sarudzo. Zvaizopfava zvokundikana. Muchiitiko ichocho, ndarira ndiyo chete sarudzo yakarurama nekuda kwekushivirira kwayo kwakanyanya. PVC hainawo kudzivirira ku dezincification, maitiro apo mamwe marudzi emvura anogona kubvongodza zinc kubva mundarira, zvichiita kuti iite brittle. Kune akawanda mabasa emvura inotonhora, PVC inopa zvirinani kuvimbika kwenguva refu uye kukosha.
PVC vs. Brass: Chii chirinani?
| Feature | PVC irinani kune… | Brass irinani kune… |
|---|---|---|
| Tembiricha | Cold Water Systems (< 60°C / 140°F) | Mvura Inopisa & Steam Systems |
| Corrosion | Mvura yemunyu, Fertilizer, Mild Chemicals | Mvura inonwiwa ine pH yakaenzana |
| Pressure | Standard Water Pressure (kusvika ku150 PSI) | High-Pressure Air kana Fluid |
| Mutengo | Yakakura Scale Projects, Budget-Kuziva Mabasa | Zvishandiso Zvinoda Kusimba Kwakanyanya |
Ndeipi iri nani ndarira kana PVC tsoka mavharuvhu?
Pombi yako inoramba ichirasikirwa nehukuru hwayo, ichikumanikidza kuti uitangezve nguva dzose. Unoda vharafu yetsoka isingakundikane, asi inenge iri pasi pemvura uye isingaonekwi.
Kune yakawanda yepombi yekushandisa mvura, PVC tsoka yevharuvhu iri nani zvakanyanya. Iyo ine huremu huremu, iyo inoderedza kushungurudza papombi, uye kusiyana nendarira, inodzivirira zvachose kune ngura uye kuora kunokonzera kukanganisa kwevhavha yetsoka.
Varuvhu yetsoka inorarama hupenyu hwakaoma. Inogara pasi petsime kana tangi, inogara yakanyura mumvura. Izvi zvinoita kuti ngura ive muvengi wekutanga. Kunyange zvazvo brass ichiita seyakaoma, uku kunyura kunogara kuchinyura ndiko kunonyanya kunetseka. Nokufamba kwenguva, mvura inoshatisa simbi, kunyanya yakapfava yemukati chitubu kana hinge michina, zvichiita kuti ibate yakavhurika kana kuvharika. Iyo valve inotadza kubata prime kana kumisa mvura kuyerera zvachose. Nokuti PVC ipurasitiki, haigoni kuita ngura. Nhengo dzomukati dzePntek tsoka dzemakumbo edu dzakagadzirwawo nezvinhu zvisingasviki, saka vanogona kugara pasi pemvura kwemakore uye vachiri kushanda zvakakwana. Imwe mukana mukuru uremu. Ivhavha yetsoka yendarira inorema inoisa kushushikana kwakawanda papombi yekukweva, zvichikonzera kuti ikotame kana kutyoka. A lightweightPVC tsoka vharafuzviri nyore kuisa uye kutsigira.
Chii chinonzi PVC bhora valve inoshandiswa?
Une purojekiti ine mitsetse yemvura yakawanda. Iwe unoda inokwanisika uye yakavimbika nzira yekudzora kuyerera mune yega yega pasina kunetseka nezve ramangwana matambudziko kubva ngura kana kuora.
A PVC bhora vharafu rinoshandiswa kupa kukurumidza on/off kudzora mu inotonhora mvura masisitimu. Ndiyo sarudzo yekusarudza yekudiridza, madziva ekutuhwina, aquaculture, uye pombi dzemvura zvakajairika uko mutengo wayo wakaderera uye hunhu hwekudzivirira ngura kwakakosha.
Ngatitarisei kune chaiwo mabasa apo PVC inokunda. Forkudiridza nekurima, mavharuvhu aya akakwana. Inogona kuvigwa muvhu kana kushandiswa nemitsara yefetereza pasina njodzi yekuora kubva munyoro kana makemikari. Fordziva dzokushambira uye spas, PVC dzemvura ndiyo indasitiri mwero nokuda kwechikonzero. Iyo haina kukanganiswa zvachose neklorini, munyu, uye mamwe makemikari edziva angakurumidza kuparadza zvikamu zvesimbi. Ndinogara ndichiudza Budi kutiaquaculturemusika wakakwana zvakakwana. Varimi vehove vanoda kudzora mvura chaiyo, uye havagone kuve nesimbi inopinza mumvura uye ichikuvadza pfuma yavo. PVC inert, yakachengeteka, uye yakavimbika. Pakupedzisira, kune chero basa ripi zvaro remvura inotonhora, sechivharo chikuru che sprinkler system kana kunyura nyore, PVC ball valve inopa yakaderera-mutengo, moto-uye-kukanganwa mhinduro yaunoziva kuti ichashanda paunoda.
Chii chinonzi bhora rendarira valve rinoshandiswa?
Uri kugadzira tambo yemvura inopisa kana mhepo yakamanikidzwa. Ivharuvhu yepurasitiki yakajairika inogona kuva nengozi uye inogona kuputika. Unoda vharafu yakasimba zvakakwana pabasa racho.
A bhora rendarira vharafurinoshandiswa pakuda maapplications anoda kushivirira kwakanyanya, kukwira kwepressure ratings, uye kusimba kwakanyanya kwemuviri. Iyo inonyanya kushandiswa ndeye mitsetse yemvura inopisa, gasi remvura, uye masisitimu emhepo akamanikidzwa mumaindasitiri.
Brass ndiro bhiza rekushanda remabasa ayo PVC asingagone kubata. Simba rayo guru ndirokupisa kuramba. Nepo PVC ichipfava pamusoro pe140 ° F (60 ° C), mhangura inogona kubata zviri nyore tembiricha inopfuura 200 ° F (93 ° C), ichiita iyo yega sarudzo kune inopisa mvura inopisa uye mimwe mitsetse yemvura inopisa. The next advantage ispressure. Iyo yakajairwa PVC bhora vharafu inowanzopihwa 150 PSI. Mavharuvhu mazhinji ebhora rendarira akatemerwa 600 PSI kana kupfuura, zvichiita kuti ave akakosha kune yakakwirira-kudzvanywa masisitimu senge.mitsara yemhepo yakamanikidzwa. Pakupedzisira, panesimba rezvinhu. Zvepombi dzemvuragasi rechisikigo, makodhi ekuvaka anogara achida mavharuvhu esimbi sendarira. Muchiitiko chemoto, vharuvhu yepurasitiki inonyunguduka uye kuburitsa gasi, nepo vharafu yendarira yaizoramba yakasimba. Kune chero kunyorera uko kupisa, kudzvanywa kwakanyanya, kana kuchengetedzwa kwemoto kuri kunetsekana, brass ndiyo chaiyo uye chete nyanzvi sarudzo.
Mhedziso
Sarudzo pakati pePVC nendarira ndeyekushandisa. Sarudza PVC nokuda kwayo isingakundiki corrosion kuramba mumvura inotonhora uye sarudza ndarira nokuda kwesimba rayo pakupisa uye high pressure.
