Echokwadi mavharuvhu ebhora remubatanidzwa akakuriswa nesaizi yemupombi (NPS) yaanobatana nayo, senge 1/2 ″, 1 ″, kana 2 ″. Saizi iyi inoreva dhayamita yemukati yepombi inoenderana, kwete zviyero zvemuviri zvevharuvhu, kuve nechokwadi chekukwana kwakakwana.

Iyi saizi inoita seyakapusa, asi ndipo panoitika zvikanganiso zvakawanda. Mumwe wangu wekuIndonesia, Budi, anonyatsoziva izvi. Vatengi vake, kubva kumakondirakiti makuru kusvika kune vatengesi vepanzvimbo, havakwanise kutenga mismatch pa-saiti. Kurongeka kumwe chete kwakashata kunogona kukanganisa iyo yese yekugovera cheni uye chirongwa chenguva yeprojekiti. Ndiko kusaka tichigara takatarisa pakujeka. Ngatiburitsei mibvunzo yakajairika nezve aya akakosha mavharuvhu kuti tive nechokwadi chekuti odha yese ndiyo chaiyo kubva pakutanga.

Chii chechokwadi chekubatana bhora vharafu?

Ivhavha inokundikana, asi inonamirwa zvachose mumutsara. Iye zvino iwe unofanirwa kudonhedza iyo system yese uye kucheka chikamu chose chepombi kungogadzirisa nyore.

A yechokwadi yemubatanidzwa bhora vharuvhu dhizaini-matatu. Iine mutumbi wepakati unogona kubviswa nyore nyore kugadzirisa kana kuchinjwa nekusunungura maviri "mubatanidzwa" nzungu, pasina kumbocheka pombi yakabatana.

Ngatitaurei kuti sei dhizaini iyi yakakosha kune nyanzvi. Chikamu che "chokwadi chekubatana" chinoreva zvakananga kune zvakabatanidzwa kumativi ose maviri evharuvhu. Kusiyana nechiyerocompact valveiyo inonyungudika zvachose mumutsara, achokwadi chekubatana valveine zvikamu zvitatu zvakasiyana zvinogona kuparadzaniswa.

Izvo Zvikamu Zvikuru

• Zvikamu zviviri:Aya ndiwo magumo akabatanidzwa zvachose kumapombi, kazhinji kuburikidza nesolvent welding yePVC. Ivo vanogadzira iyo yakagadzikana yekubatanidza kune yako system.
• Imwe Central Body:Uyu ndiwo musimboti wevhavha. Iyo ine bhora mashandiro, dzinde, mubato, uye zvisimbiso. Inogara zvakachengetedzeka pakati pemapendekete maviri.
• Maviri Union Nuts:Idzi nzungu huru, dzine shinda ndiwo mashiripiti. Vanotsvedza pamusoro pematanho uye vanokwenya pane yepakati muviri, vachidhonza zvese pamwe nekugadzira yakasimba,mvura isina chisimbisoneO-mhete.

Izvimodular designinoshandura mutambo wekugadzirisa. Iwe unongosunungura nzungu, uye muviri wevhavha yose unosimudza kunze. Ichi chinhu chakakosha kukosha kwatinopa kuPntek-smart dhizaini inochengetedza vashandi, mari, uye system downtime.

Nzira yekuziva sei saizi yevhavha yebhora?

Une vharafu muruoko rwako, asi hapana mavanga ari pachena. Iwe unofanirwa kuodha yekutsiva, asi kufungidzira saizi ndiyo resipi yezvikanganiso zvinodhura uye kunonoka kweprojekiti.

Ukuru hwevhavhavha yebhora hunenge hunogara huchinyorwa kana kudhindwa zvakananga pamutumbi wevharuvhu. Tsvaga nhamba inoteverwa ne”inch” (“) kana “DN” (Diameter Nominal) yemametric size.Nhamba iyi inofambirana nesaizi yepombi yainokwana.

Valve saizi yakavakirwa pane system inonziNominal Pipe Size (NPS). Izvi zvinogona kuvhiringidza pakutanga nekuti nhamba haisi chiyero chakananga chechero chikamu chevhavha pachayo. Ireferensi yakajairika.

Kunzwisisa Zviratidzo

• Nominal Pipe Size (NPS):Pamavharuvhu ePVC, uchaona saizi dzakajairika senge 1/2 ″, 3/4 ″, 1 ″, 1 1/2 ″, 2 ″, zvichingodaro. Izvi zvinokuudza kuti yakagadzirirwa kukwana papombi ine saizi yezita rimwe chete. Muchidimbu, 1 ″ vharafu inokodzera 1″ pombi. Ndizvo zvakananga.
• Diameter Nominal (DN):Mumisika inoshandisa metric zviyero, iwe unowanzo kuona DN mamaki pachinzvimbo. Semuenzaniso, DN 25 ndiyo metric yakaenzana neNPS 1 ″. Ingori gungano rezita rakasiyana reiyo indasitiri-yakajairwa pombi saizi.

Paunenge uchiongorora vharafu, tarisa mubato kana muviri mukuru. Ukuru hunowanzo umbwa mukati chaimo mupurasitiki. Kana pasina zviratidzo zvachose, nzira chete yechokwadi ndeyekuyera mukati mepakati pevhavha yesocket, iyo iyo pombi inoenda. Chiyero ichi chinonyatsoenderana nedhayamita yekunze yepombi inoenderana iyo inoitirwa.

Ndeupi musiyano uripo pakati pemubatanidzwa wemubatanidzwa uye mavharuvhu maviri emubatanidzwa bhora?

Wakatenga "union" valve uchitarisira kubviswa nyore. Asi paunoedza kuisevhisi, unoona kuti divi rimwe chete ndiro rinokurura, zvoita kuti ukotame uye uise pombi kuti ibude.

Ivhavhavha yemubatanidzwa ine nzungu imwe yemubatanidzwa, inobvumira kubviswa kubva kune rumwe rutivi rwepombi. A double union (kana true union) ball valve ine nzungu mbiri dzemubatanidzwa, zvichiita kuti muviri ubviswe zvachose pasina kusimbisa pombi.

Musiyano uyu wakanyanya kukosha kune yechokwadi serviceability uye basa rehunyanzvi. Nepo vharuvhu yemubatanidzwa iri nani zvishoma pane yakajairwa compact valve, haipe kuchinjika kwakazara kunodiwa pakugadzirisa kwenguva refu.

Nei Double Union iri iyo Professional Standard

• Single Union:Nenyuti imwe yemubatanidzwa, rimwe divi revhavha rinogara rakagadziriswa kumagumo epombi. Kuti uibvise, unosunungura nati imwe chete, asi wozofanira kudhonza kana kukotama pombi kuti vharuvhu ibude. Izvi zvinoisa kushushikana kukuru pane zvimwe zvigadziriso uye zvinogona kukonzera kuvuza kutsva pasi pemutsara. Ndiyo mhinduro isina kukwana inogona kuunza mamwe matambudziko.
• Double Union (Mubatanidzwa Wechokwadi):Iyi ndiyo chiyero chehunyanzvi uye zvatinogadzira paPntek. Iine nzungu mbiri dzemubatanidzwa, zvese zvakabatanidzwa pombi zvinogona kusunungurwa zvakazvimirira. Muviri wevharuvhu unobva wasimudzwa wakananga kumusoro uye kunze kwemutsara uine zero kushushikana papombi. Izvi zvakakosha kana vharuvhu yakaiswa munzvimbo yakamanikana kana yakabatana nemidziyo inonzwisisika sepombi kana sefa.

Ndeipi saizi yakajairwa yevharuvhu yebhora yakazara?

Iwe wakaisa vharafu, asi ikozvino kumanikidza kwemvura muhurongwa kunoratidzika kuderera. Iwe unoziva kuti gomba riri mukati mevharuvhu idiki zvakanyanya pane pombi, richigadzira bhodhoro rinodzivirira kuyerera.

Muchibhorani chizere (kana chizere) chevhavha yebhora, ukuru hwegomba mubhora hunogadzirwa kuti huenderane nedhayamita yemukati yepombi. Saka, 1 ″ yakazara bore valve ine gomba iro zvakare 1 ″ mudhayamita, ichivimbisa zero kuyerera kurambidzwa.

Izwi rokuti "full bore”Inoreva magadzirirwo emukati nekushanda kwevharuvhu, kwete saizi yayo yekunze yekubatanidza.Iyo chinhu chakakosha pakubudirira mune dzakawanda maapplication.

Full Bore vs. Standard Port

• Full Bore (Chiteshi Chakazara):Gomba riri mubhora rakaenzana nedhayamita yemukati (ID) yepombi yayakabatana nayo. Kune 2 ″ vharafu, gomba iri zvakare 2 ″. Iyi dhizaini inogadzira nzira yakatsetseka, isina kuvharika zvachose yemvura. Kana vharuvhu yakavhurika, inoita kunge haipo. Izvi zvakakosha kune masisitimu kwaunoda kukwirisa kuyerera uye kuderedza kudonhedza kudonha, senge mitsetse mikuru yemvura, pombi yekudyara, kana madhiraini masisitimu.
• Chiteshi cheStandard (Chiteshi chakaderedzwa):Muchigadziro ichi, gomba kuburikidza nebhora rimwe saizi idiki pane saizi yepombi. A 1″ standard port valve inogona kunge iine 3/4″ gomba. Izvi zvishoma zvinorambidzwa zvinogamuchirwa mune zvakawanda zvinoshandiswa uye zvinoita kuti valve pachayo ive diki, yakareruka, uye isingadhure kugadzira.

PaPntek, mavharuvhu edu echokwadi emubatanidzwa akazara. Isu tinotenda mukupa mhinduro dzinosimudzira mashandiro ehurongwa, kwete kudzitadzisa.

Mhedziso

Saizi yechokwadi yevharuvhu yemubatanidzwa inoenderana nepombi yavanokwana. Kusarudza mubatanidzwa wakapetwa kaviri, yakazara bore dhizaini inovimbisa kugadzirisa kuri nyore uye zero kuyerera kurambidzwa kune yakavimbika, nyanzvi system.
