Iwe unoona "vharuvhu yemubatanidzwa" uye "vharuvhu yebhora" yakanyorwa, asi zvakasiyana here? Kusarudza zvisizvo zvinoreva kuti ungangofanira kucheka vharafu yakanaka gare gare kuti ungosevhisi pombi.
Ivhavha yebhora inotsanangura nzira yekuvhara (bhora). Mubatanidzwa unotsanangura mhando yekubatanidza inobvumira kubvisa (union nuts). Havana kupindirana; vharuvhu inonyanyo siyana-siyana ndeye achokwadi mubatanidzwa bhora vharafu, iyo inobatanidza zvose zviri zviviri.
Iyi ndiyo imwe yeanonyanya kuzivikanwa mapoinzi enyonganiso yandinoona, uye mutsauko wakakosha kune chero nyanzvi. Ndinowanzo kurukura izvi nemumwe wangu Budi wekuIndonesia, nekuti vatengi vake vanoda mhinduro dzisiri dzinoshanda chete asiwo dzinoshanda kuchengetedza mukufamba kwenguva. Chokwadi ndechekuti, aya mazwi anotsanangura zvinhu zviviri zvakasiyana: chimwe chinokuudzaseivalve inoshanda, uye imwe inokuudzakuti inobatanidza seiku pombi. Kunzwisisa mutsauko uyu kwakakosha pakugadzira yakangwara, inoshanda sisitimu.
Ndeupi musiyano uripo pakati pevharuvhu yebhora nevhavhavha yebhora remubatanidzwa?
Iwe wakaisa chiyero chebhora vharafu, uchichiisa zvachose mumutsara. Kwapera gore, chisimbiso chinokundikana, uye iwe unoona sarudzo yako chete ndeyekucheka vharafu rose uye kutanga patsva.
A standard ball valve is a single, zvachose yakaiswa unit. Iyo yechokwadi yemubatanidzwa bhora vharuvhu yakasunga nzungu dzinokuita kuti ubvise muviri wepakati wevharuvhu pasina kucheka pombi, kuita kugadzirisa kana kutsiva kuve nyore.
Uyu ndiwo musiyano unonyanya kukosha wekuronga kwenguva refu. Funga nezvazvo maererano nezwi rekuti "chisingaperi" maringe ne"kushandirwa." A mwero, compact bhora vharafu inonyungudutsa-welded yakananga mupombi. Kana yangopinda, inenge yapinda zvachose. Izvi zvakanaka kune mitsetse yakapfava, isiri-yakakosha. Achokwadi mubatanidzwa bhora vharafu, zvisinei, rakagadzirirwa remangwana. Iwe solvent-weld maviri akapatsanurwa tailpiece kune pombi, uye huru vharafu muviri unogara pakati pavo. Inobatwa panzvimbo mbiri huru yemubatanidzwa nzungu. Kana iwe uchida kutsiva zvisimbiso zvevharuvhu kana muviri wese, unongosunungura nzungu woisimudza. Ichi ndicho chikonzero isu paPntek tichitsigira dhizaini yemubatanidzwa; inoshandura kugadzirisa kukuru kuita basa rakareruka remaminitsi mashanu.
Standard vs. True Union Ball Valve
| Feature | Standard (Compact) Bhora Valve | Chokwadi Union Ball Valve |
|---|---|---|
| Installation | Permanent (solvent-welded) | Inoshanda (union nuts) |
| Maintenance | Inoda kucheka pombi | Muviri unobvisa kuti zvive nyore kugadzirisa |
| Mutengo Wokutanga | Lower | Higher |
| Kukosha Kwenguva Yakareba | Yakaderera (inodhura kugadzirisa) | Yakakwirira (inochengetedza nguva nekushanda) |
Chii chinonzi vharuvhu yemubatanidzwa?
Iwe unoona izwi rekuti "vharuvhu yemubatanidzwa" uye unofunga kuti iboka rakasiyana zvachose, sevhavha yegedhi kana cheki vharuvhu. Kuzengurira uku kunogona kukuchengetedza kubva pakusarudza sarudzo inoshanda.
Ivhavha yemubatanidzwa haisi mhando yemaitiro, asi rudzi rwekubatanidza. Ivhavhavha inoshandisa mubatanidzwa fittings (threaded nuts) kubatanidza muviri wevharuvhu kumagumo epombi, zvichiita kuti zvive nyore kubviswa.
Iyo "mubatanidzwa" pachayo chikamu chakanakisa cheinjiniya. Inoumbwa nezvikamu zvitatu zvikuru: zvidimbu zviviri zvinosungirirwa papombi (zvichida nesolvent weld kana shinda), uye nati ine thread inodhonza pamwe chete kugadzira chisimbiso. A “vharafu yemubatanidzwa” inongogadzira chinhu ichi mukugadzirwa kwevharuvhu.Saka, unogona kuva nevharuvhu yebhora remubatanidzwa, yechokwadi yevharuvhu yekutarisa mubatanidzwa, kana vharuvhu yemubatanidzwa diaphragm yechokwadi. Chinangwa chinogara chakafanana:serviceability. Inokubvumira kuti uzviparadzanise uye ubvise chidimbu chemidziyo pasina kudzvinyirira hurongwa hwose kana, kunyanya kukosha, pasina kutema pombi yako. Iyi modular maitiro ndiyo hwaro hwemazuva ano, hunoshanda pombi dhizaini uye chikamu chepakati che "win-win" uzivi hwandinogovana nevabatsiri vakaita saBudi. Iyo inoponesa vatengi vake nguva nemari pamusoro pehupenyu hwehurongwa.
Ndeapi marudzi matatu emavharuvhu?
Wanga uchishandisa mavharuvhu ebhora kune zvese, asi imwe application inoda chaiyo kuyerera kwekutonga. Unoedza kuvhara vharavha yebhora, asi zvakaoma kudzora uye unonzwa ruzha runoshamisa.
Iwo matatu makuru anoshanda marudzi emavharuvhu anoti Shut-Off (On/Off), Throttling (Regulating), uye Non-Return (Backflow Prevention). Rudzi rumwe norumwe rwakagadzirirwa basa rakasiyana zvachose, uye kushandisa risiri iro rinogona kukuvadza system yako.
Kuziva zvikamu zvekutanga kwakakosha pakusarudza chishandiso chakakodzera chebasa racho. Kushandisa vharafu isiriyo kukanganisa kwakajairika. Vhuru yebhora ikuvhara-vharavhavha; rakagadzirwa kuti rivhurike zvakazara kana kuvharwa zvakazara. Kuishandisa throttle kuyerera kunogona kukonzera mhirizhonga inobvisa bhora nezvigaro, zvichiita kuti itadze.
Valve Categories Inotsanangurwa
| Valve Type | Primary Function | Common Mienzaniso | Best Use Case |
|---|---|---|---|
| Kuvhara-Kudzima (Kubatidzwa/Kudzima) | Kumisa zvachose kana kubvumira kuyerera. | Bhora Vavhavha, Gedhi Vavhavha, Butterfly Valve | Kuparadzanisa zvikamu kana midziyo. |
| Kudzora (Regulating) | Kudzora kumhanya kana kudzvanywa kwekuyerera. | Globe Valve, Tsono Valve | Kugadzirisa kuyerera chaiko. |
| Kusadzoka (Backflow) | Kubvumira kuyerera munzira imwe chete. | Tarisa Vhuru, Rutsoka rwetsoka | Kudzivirira pombi kubva kumashure. |
Ndeapi marudzi mana emavharuvhu ebhora?
Iwe unoziva nezve echokwadi mavharuvhu emubatanidzwa, asi iwe unoona dzimwe sarudzo senge "compact" kana "chimwe-chidimbu." Iwe hauna chokwadi chekuti ndechipi chakanakira maapplication akasiyana, uye unogona kunge uchibhadhara zvakanyanya kune zvausingade.
Iwo mana makuru emhando dzebhora mavharuvhu anosiyaniswa nekuvakwa kwemuviri: Imwe-Piece (yakasimwa), Mbiri-Piece (Threaded body), Three-Piece (sechokwadi mubatanidzwa), uye Compact (yakareruka, yehupfumi dhizaini, kazhinji-chidimbu chimwe).
Nepo magadzirirwo emukati akafanana (bhora rinotenderera), magadzirirwo emuviri anoraira mutengo wayo uye kushanda. Munyika yePVC, isu tinonyanya kutarisa pane imwe-chidimbu / compact uye matatu-chidimbu / echokwadi mubatanidzwa magadzirirwo.
- Chidimu chimwe /Compact Ball Valve:Muviri wevharuvhu chinhu chimwe chete, chakavharwa. Iyi ndiyo yakanyanya hupfumi dhizaini. Iyo yakareruka, yakapusa, uye yakanakira maapplication uko kugadzirisa kusiri kunetseka uye mutengo ndiye wekutanga mutyairi.
- Maviri-Piece Ball Valve:Muviri wakagadzirwa nezvidimbu zviviri zvinokochekera pamwe chete, zvichiteya bhora nekusunga mukati. Izvi zvinobvumira kumwe kugadzirisa asi kazhinji zvinoda kuibvisa kubva pamutsetse. Zvinonyanya kuwanda mumavharuvhu esimbi.
- Zvidimbu zvitatu (Chokwadi Union) Bhora Vavha:Iyi ndiyo premium dhizaini. Iyo ine maviri ekupedzisira ekubatanidza (tailpieces) uye yepakati muviri. Izvi zvinobvumira muviri mukuru kubviswa kuti ugadziriswe kana kuchinjwa pasina kukanganisa pombi. Iyi ndiyo yakavimbika uye inodhura-inoshanda sarudzo yeakakosha maapplication kwenguva refu.
PaPntek, isu tinotarisa pakupa yakanakisa kompakiti uyechokwadi mubatanidzwa mavharuvhu, kupa vatinoshanda navo seBudi sarudzo dzakakodzera kune chero chinodiwa nemutengi.
Mhedziso
Varuvhu yebhora ndiyo nzira; mubatanidzwa mubatanidzwa. Iyo yechokwadi yemubatanidzwa bhora vharafu inovasanganisa, ichipa kutonga kwepamusoro uye nyore kugadzirisa kune chero nyanzvi dzepombi system.
