Unoona "vharuvhu yemubatanidzwa" ne "vharuvhu yebhora" zvakanyorwa, asi zvakasiyana here? Kusarudza zvisiri izvo zvinoreva kuti ungangofanira kucheka vharuvhu yakanaka kwazvo gare gare kuti ugadzirise pombi.
Vharuvhu yebhora inotsanangura nzira yekudzima (bhora). Vharuvhu inotsanangura rudzi rwekubatanidza runobvumira kubviswa (nzungu dzemubatanidzwa). Hadzisi dzakasiyana; vharuvhu inonyanya kushandiswa ivharuvhu yebhora yemubatanidzwa wechokwadi, iyo inosanganisa zvese zviri zviviri.
Iyi ndeimwe yepfungwa dzinowanzo vhiringidza dzandinoona, uye musiyano wakakosha kune chero nyanzvi. Ndinowanzo kurukura izvi nemumwe wangu Budi muIndonesia, nekuti vatengi vake vanoda mhinduro dzisiri dzekushanda chete asiwo dzinoshanda kuchengetedza kwenguva refu. Chokwadi ndechekuti, mazwi aya anotsanangura zvinhu zviviri zvakasiyana: chimwe chinokuudzaseivharuvhu inoshanda, uye imwe inokuudzakuti zvinobatana seikupombi. Kunzwisisa musiyano uyu ndicho chinhu chikuru pakugadzira sisitimu yakangwara uye inoshanda.
Ndeupi musiyano uripo pakati pevharuvhu yebhora nevharuvhu yebhora yemubatanidzwa?
Waisa vharuvhu yebhora yakajairika, uchiinamira zvachose mutambo. Gore rinotevera, chisimbiso chinokundikana, uye unoona kuti sarudzo yako chete ndeyekucheka vharuvhu yese wotanga patsva.
Vharuvhu yebhora yakajairika chinhu chimwe chete, chakaiswa zvachose. Vharuvhu yebhora yemubatanidzwa chaiyo ine nzungu dzakarukwa dzinokubvumira kubvisa muviri wevharuvhu yepakati pasina kucheka pombi, zvichiita kuti kugadzirisa kana kutsiva zvive nyore.
Uyu ndiwo musiyano unonyanya kukosha pakuronga kwenguva refu. Funga nezvazvo se "chigarire" kana "chinoshanda." Vharuvhu yebhora yakajairika, yakamanikana inosungirirwa zvakananga mupaipi. Kana yangoiswa, inenge yagadzirira zvachose. Izvi zvakanaka kune mitsetse iri nyore, isiri yekuongorora. Avharuvhu yebhora yemubatanidzwa wechokwadiZvisinei, yakagadzirirwa ramangwana. Unosanganisa zvidimbu zviviri zvemusana wepombi, uye vharuvhu huru inogara pakati pazvo. Inobatwa panzvimbo nenyuchi mbiri huru dzemuchina. Kana uchida kutsiva zvisimbiso zvevharuvhu kana muviri wese, unongosunungura nzungu wodziburitsa. Ndokusaka isu kuPntek tichitsigira dhizaini yemuchina wechokwadi; inoshandura kugadzirisa kukuru kuita basa riri nyore remaminitsi mashanu.
Valve yeBhora yeVarau ...
| Chinhu | Vharuvhu yeBhora Yakajairika (Yakamanikana) | Valve yeBhora reUnion Yechokwadi |
|---|---|---|
| Kuiswa | Chinogara (chakasungirirwa nemushonga) | Inogadziriswa (nzungu dzemubatanidzwa) |
| Kugadzirisa | Zvinoda kucheka pombi | Kubviswa kwemuviri kuti zvive nyore kugadzirisa |
| Mutengo wekutanga | Zasi | Yepamusoro |
| Kukosha Kwenguva Refu | Zvishoma (kugadzirisa kunodhura) | Yakakwirira (inochengetedza nguva nebasa) |
Chii chinonzi union valve?
Unoona izwi rekuti "union valve" wobva wafunga kuti imhando yakasiyana zvachose, senge gate valve kana check valve. Kuzeza uku kunogona kukutadzisa kusarudza sarudzo inonyanya kushanda.
Vharuvhu yekubatanidza haisi mhando yemuchina, asi rudzi rwekubatanidza. Ivharuvhu chero ipi zvayo inoshandisa union fittings (nzungu dzakarukwa) kubatanidza muviri wevharuvhu kumagumo epombi, zvichiita kuti zvive nyore kubvisa.
"Mubatanidzwa" pachawo inyanzvi yeinjiniya. Ine zvikamu zvikuru zvitatu: zvidimbu zviviri zvemusana zvinobatana nepaipi (kungave nekusveta solvent kana shinda), uye nati ine shinda inovabatanidza pamwe chete kuti vagadzire chisimbiso. A "vharuvhu yemubatanidzwa"Inongowedzera chimiro ichi mukugadzirwa kwevharuvhu. Saka, unogona kuva nevharuvhu yebhora remubatanidzwa wechokwadi, vharuvhu yekutarisa mubatanidzwa wechokwadi, kana vharuvhu yemubatanidzwa wechokwadi. Chinangwa chinogara chakafanana:kugona kushanda. Inokubvumira kubvisa mudziyo wega wega pasina kudzvinyirira sisitimu yese kana, chinonyanya kukosha, pasina kucheka pombi yako. Iyi nzira yekubatanidza ndiyo hwaro hwekugadzira mapaipi emvura emazuva ano uye inoshanda uye chikamu chikuru chepfungwa yekuti "zvose zvinobudirira" zvandinogovana nevamwe vakaita saBudi. Inochengetedza vatengi vake nguva nemari muhupenyu hwese hwesisitimu.
Ndeapi marudzi matatu emavharuvhu?
Wave uchishandisa mavharuvhu ebhora pazvinhu zvese, asi imwe chete inoda kudzorwa kwakanyatsojeka kwemvura. Unoedza kuvhara vharuvhu yebhora zvishoma, asi zvakaoma kudzora uye unonzwa ruzha rusinganzwisisike.
Mhando nhatu huru dzemavharuvhu dzinoshanda zvikuru ndedzekuti Shut-Off (On/Off), Throttling (Regulating), uye Non-Return (Backflow Prevention). Rudzi rumwe nerumwe rwakagadzirirwa basa rakasiyana zvachose, uye kushandisa risiri iro kunogona kukuvadza system yako.
Kuziva zvikamu zvekutanga kwakakosha pakusarudza chishandiso chakakodzera basa racho. Kushandisa vharuvhu isiriyo chikanganiso chinowanzoitika. Vharuvhu yebhora ivharuvhu yekudzima; yakagadzirwa kuti ivhurike zvizere kana kuti ivharwe zvizere. Kuishandisa kutenderedza bhora kunogona kukonzera kusagadzikana kunokuvadza bhora nezvigaro, zvichiita kuti ritadze kushanda.
Tsanangudzo yeMapoka eValve
| Rudzi rweVharuvhu | Basa Guru | Mienzaniso Yakajairika | Nyaya Yakanakisisa Yokushandisa |
|---|---|---|---|
| Kudzima (Kubatidza/Kudzima) | Kumisa zvachose kana kubvumira kuyerera kwemvura. | Vharuvhu yeBhora, Vharuvhu yeGedhi, Vharuvhu yeBhatafurayi | Kuparadzanisa zvikamu kana michina. |
| Kudzora Kurovera (Kudzora) | Kudzora kumhanya kana kumanikidzwa kwekuyerera kwemvura. | Vharuvhu Yepasi, Vharuvhu Yetsono | Kugadzirisa mwero chaiwo wekuyerera kwemvura. |
| Kusadzoka (Kudzokera shure) | Kubvumira kuyerera kwemvura munzira imwe chete. | Vharuvhu Yekutarisa, Vharuvhu Yetsoka | Kudzivirira pombi kubva pakudzokera shure. |
Ndedzipi mhando ina dzemavharuvhu ebhora?
Unoziva nezvemavharuvhu chaiwo emagetsi, asi unoona dzimwe sarudzo dzakadai se "compact" kana "one-piece." Hauzive kuti ndeipi yakanakira maapplication akasiyana, uye ungangove uchibhadhara zvakawandisa kune maficha ausingade.
Mhando huru ina dzemavharuvhu ebhora dzinosiyaniswa nekugadzirwa kwemuviri: Chidimbu Chimwe (chakavharwa), Chidimbu Chechipiri (muviri une shinda), Chidimbu Chetatu (senge mubatanidzwa chaiwo), uye Chidiki (dhizaini iri nyore, isingadhuri, kazhinji chidimbu chimwe chete).
Kunyange zvazvo mashandiro emukati akafanana (bhora rinotenderera), magadzirirwo emuviri anotsanangura mutengo waro uye kugona kwaro kushanda. Munyika yePVC, tinonyanya kutarisa pakugadzira magadzirirwo emuchina wechinhu chimwe chete/chidiki uye chetatu/chechokwadi.
- Chidimu chimwe /Vharuvhu yeBhora Yakamanikana:Muviri wevharuvhu chinhu chimwe chete, chakavharwa. Iyi ndiyo dhizaini inodhura zvakanyanya. Yakareruka, iri nyore, uye yakakwana kune mashandisirwo ayo kugadzirisa kusiri kunetseka uye mari ndiyo inonyanya kukosha.
- Vharuvhu yeBhora reTwo-Piece:Muviri wacho wakagadzirwa nezvidimbu zviviri zvinosunga bhora pamwe chete, zvichisunga bhora uye zvinovhara mukati. Izvi zvinobvumira kugadziriswa asi kazhinji zvinoda kubviswa patambo. Zvinonyanya kuwanikwa mumavharuvhu esimbi.
- Zvidimbu Zvitatu (True Union) Ball Valve:Iyi ndiyo dhizaini yepamusoro. Ine zvibatanidza zviviri (zvimedu zvemumashure) nechikamu chepakati. Izvi zvinobvumira chikamu chikuru kubviswa kuti chigadzirwe kana kutsiviwa pasina kukanganisa pombi. Iyi ndiyo sarudzo yakavimbika uye isingadhuri yekushandisa kwenguva yakareba.
KuPntek, tinonyanya kutarisa pakupa michina yakanakisa uyemavharuvhu emubatanidzwa wechokwadi, zvichipa vatinoshanda navo vakaita saBudi sarudzo dzakakodzera chero zvinodiwa nevatengi.
Mhedziso
Vharuvhu yebhora inzira inoshanda; kubatana inzira yekubatanidza. Vharuvhu yebhora yemubatanidzwa chaiyo inosanganisa izvi, ichipa kudzora kwakanyanya uye kugadzirisa kuri nyore kune chero sisitimu yepombi yehunyanzvi.
