Uri kunetseka here nezvekusarudza rudzi rwekubatanidza rwusina kunaka pamavharuvhu ako? Tambo isina kuenderana kana kubatana kusina kunaka zvinogona kukonzera kubuda kwemvura nguva dzose, kunonoka kwepurojekiti, uye kukanganisa mukurumbira wako webasa.
A vharuvhu yebhora yakarukwaivharuvhu inoshandisa shinda dzekuruu pamagumo ayo kuti ibatanidze papombi kana pakuisa. Dhizaini iyi inobvumira kuiswa nekubviswa zviri nyore nezvishandiso zvepakutanga, pasina kuda michina yakakosha yekuwedera kana yekunamira. Inouya mumhando dzakasiyana dzeshinda.
Kubatana uku kuri nyore ndechimwe chezvinhu zvinonyanya kuwanikwa pasi rose, asi ruzivo rwacho ndirwo runokosha. Semunhu akavaka kambani ine mhinduro dzepasi rose dzekutarisira mvura, ndinoziva kuti kunyange chinhu chiri nyore chinofanira kunge chakarurama. Kune maneja wekutenga saCarlos, kupa vharuvhu yakakodzera zvinoreva kuti vatengi vake vanogona kupedzisa basa ravo nekukurumidza uye zvakavimbika. Chikamu chakakosha chekuvaka purojekiti inobudirira uye kushandira pamwe kwenguva refu.
NPT yakafanana here neyakaiswa tambo?
Uri kufunga kuti tambo dzese dzakafanana here? Kuraira vharuvhu "yakarukwa" pasina kutsanangura mwero wayo kunogona kutungamira kukugamuchira zvikamu zvisingabatanidzwe, zvichikonzera kudzoka kunodhura uye kunonoka kunoshungurudza vatengi vako.
Kwete, NPT haina kufanana neyakaiswa shinda; inyaya chaiyomhandoyeshinda. "Threaded" izwi rekuti connection ye screw-in, nepo NPT (National Pipe Thread) iri standard yeUS yeshinda dzakatetepa. Mamwe ma standard, seBSPT, aripowo.
Ndinoshanda nevatinoshanda navo munyika dzinopfuura makumi mashanu, saka kutarisira mitemo chikamu chikuru chebasa rangu. Musiyano uyu wakakosha pakutengeserana kwenyika dzese. Kana Carlos wekuMexico akaraira vharuvhu yepurojekiti inoshandisa pombi yeAmerica, anoda NPT. Dai achitsvaga purojekiti ine michina yeBritain, angangodaBSPT. Dzinotaridzika zvakafanana, asi hadzienderane. Kushandisa isiriyo kuchaita kuti pave nejointi isingavharike kana kukuvadza shinda.
Kunzwisisa Maitiro Anonyanya Kuenderana Nenyaya
Kuziva musiyano uyu ndicho chinhu chikuru pakudzivirira kutadza kushanda kwekubatanidza. Kune akawanda mashandisirwo muAmerica, NPT ndiyo inowanzo shandiswa, asi zvakakosha kuziva imwe nzira.
| Chinhu | NPT (NPT) | BSPT (British Standard Pipe Taper) |
|---|---|---|
| Dunhu | Zvikurukuru kuNorth America (USA, Canada, Mexico) | UK, Europe, Asia, Australia |
| Angle yeshinda | madhigirii makumi matanhatu | madhigirii makumi mashanu nemashanu |
| Mbiri | Makomo nemapani zvakati sandara | Makomo nemapani akatenderera |
| Kuenderana | Hazvienderane neBSPT. | Hazvienderane neNPT. |
Kuna Carlos, kuisa mavharuvhu nekuisa mazita akajeka zvichienderana nehurongwa hwavo hweshinda (NPT kana BSPT) zvinodzivirira kuvhiringidzika kwevatengi vake uye zvinoita kuti vawane chikamu chakakodzera kekutanga.
Chii chinonzi vharuvhu yebhora yeNPT?
Ko purojekiti yako inoda vharuvhu yeNPT here? Kana usina chokwadi kuti izvi zvinorevei pakuiswa, unogona kupotsa danho rakakosha wozopedzisira wava nekubatana kunobuda mvura.
Vharuvhu yebhora yeNPT ingori vharuvhu yebhora inogadzirwa neshinda dzakajairika dzeNPT (National Pipe Thread). Dhizaini yakatetepa yeshinda idzi inoita kuti vharuvhu iyi ivharwe zvakasimba nekubatanidza vharuvhu painosungirirwa papombi kana painofanira kusungirirwa.
Tambo yakatetepa ndiyo chinhu chakakosha pano. Kusiyana netambo yakatwasuka pabhoti, tambo yeNPT inowedzera kukura painokura. Dhizaini iyi yakagadzirirwa kugadzira kupindirana, ichidzvanya tambo pamwe chete kuti igadzire chisimbiso. Zvisinei, chisimbiso ichi chemuchina hachina kukwana. Ndinogara ndichisimbirira kuti vatinoshanda navo vanzwisise izvi:Kubatana kweNPT kunoda chisimbiso cheshinda nguva dzoseIzvi zvinogona kuvaTepi yePTFE (tepi yeTeflon) kana pombi yemvura. Chivharo chinozadza mipata midiki iri pakati peshinda dzisingakwanise kuvharwa nesimba remakanika. Kusvetuka danho iri ndechimwe chezvikonzero zvinowanzo kukonzera kubuda kwemvura mumasystem ane shinda. Danho riri nyore rinovimbisa mhedzisiro yehunyanzvi, isingadonhedze mvura. Mavharuvhu aya anouyawo nenzira dzakasiyana, dzakadai sedzine magumo maviri eshinda echikadzi (anonyanya kuzivikanwa), kana nerumwe divi rechirume nerimwe rechikadzi kune zvinodiwa zvekubatanidza.
Unogona here kuwedzera shinda papombi yePVC?
Unofanira kubatanidza vharuvhu ine shinda kune pombi yePVC isina magumo here? Kuedza kucheka shinda zvakananga mupombi chikanganiso chikuru chichaipedza simba uye chinoita kuti isashande zvakanaka.
Ehe, unogona kuwedzera shinda, asi unofanira kushandisa adapter fitting yakakosha. Haufanire kumbocheka shinda zvakananga mumadziro epombi yePVC. Pane kudaro, unoshandisa solvent simende kunamira adapter yePVC ine shinda dzakagadzirwa kare pamucheto wepombi isina chinhu.
KuPntek, mhando uye kuchengetedzeka ndizvo zvatinonyanya kukoshesa. Kucheka shinda pamadziro epombi yePVC, kunyanya Schedule 40, kunobvisa zvinhu uye kunoita kuti pave nekumanikidzwa. Zvinoderedza zvakanyanya kumanikidzwa kwepombi uye zvinoita kuti pave nekukasira kutsemuka kana kuputika kana paine kumanikidzwa. Nzira chaiyo uye yehunyanzvi ndeyekushandisaadapta.
Nzira Yakarurama Yekuwedzera Mashinda kuPVC
- Sarudza Adapter Yakakodzera:Sarudza chinokwana adapter yePVC. Kana uchida shinda dzechirume, shandisa "adapter yechirume." Kana uchida shinda dzechikadzi, shandisa "adapter yechikadzi." Kumucheto mumwe kuchava neshinda, uye mumwe uchava soketi yakatsetseka.
- Gadzirira Pombi uye Kuiisa:Geza magumo epombi yePVC nemukati me soketi yeadaptara. Isa primer yePVC pamusoro pese.
- Isa simende yekunyungudutsa:Isa simende yePVC solvent yakaenzana pamusoro pe primer papombi nepa fitting.
- Batanidza uye Bata:Isa pombi yacho ipapo ipapo musokisi readapta uchiitenderedza zvishoma. Ibatisise zvakasimba kwemasekondi angangoita makumi matatu kuti simende iome.
Izvi zvinogadzira nzvimbo yakasimba, inogara kwenguva refu, yekubatanidza tambo dzemufekitori pasina kukanganisa kuvimbika kwepombi.
Nzira yekubatanidza PVC isina tambo?
Uri kutsvaga imwe nzira yekubatanidza tambo panzvimbo pePVC system yako here? Dzimwe nguva, chisungo chinogara chakasungirirwa chichava sarudzo yakachengeteka uye yakavimbika kune mamwe mashandisirwo.
Kuti ubatanidze PVC isina shinda, unoshandisa simende inonyungudutsa uye soketi (kana kuti "inotsvedza"). Vharuvhu yebhora resoketi ine magumo akatsetseka ayo pombi yePVC inonyura maari. Unoisa primer nesimende kuti ugadzire chisungo chinogara kwenguva refu, chakasungirirwa nemakemikari chakasimba zvikuru.
Kunyange zvazvo kubatana kwetambo kwakanaka kuti kushande zvakanaka, majoini ane solvent-weld anowanzova akasimba uye ane nzira shoma dzinogona kudonhedza mvura. KuPntek, tinopa mhinduro dzakasiyana siyana nekuti tinoziva kuti basa rega rega rakasiyana. Kune nzvimbo dzinogara dziripo uko vharuvhu isingazodi kubviswa, avharuvhu yesoketiisarudzo yakanaka kwazvo.
Kuenzanisa Mhando dzeKubatanidza PVC
Kune maneja wekutenga akaita saCarlos, kuva nesarudzo dzakasiyana zvinoreva kuti anogona kugutsa zvinodiwa nevatengi vake zviri nani. Heino pfupiso pfupi yenzira dzakajairika dzekuisa vharuvhu yebhora mumutsara wePVC:
| Rudzi rwekubatanidza | Mashandiro Azvo | Zvakanakira | Chinhu Chinobatsira |
|---|---|---|---|
| Yakarukwa neshinda | Shinda dzechirume nedzechikadzi dzakasungirirwa pamwe chete. | Kubatanidza kunogoneka; kubatanidza nesimbi. | Inogona kuputswa kuti igadziriswe kana kutsiviwa. |
| Soketi (Slip) | Pombi inonamirwa zvakananga mumasoketi evharuvhu. | Kuiswa kwechigarire; kuyerera kwakanyanya. | Inogadzira chisungo chakasimba, chisingaperi, chisingadonhedze mvura. |
| Kubatana Kwechokwadi | Muviri wevharuvhu unobviswa; zvinobatanidza zvekupedzisira zvakanamirwa. | Nzvimbo dzinoda kugadziriswa; pombi nefirita zvinobatana. | Inosanganisa weld inogara iripo uye kubviswa kwevharuvhu kuri nyore. |
| Yakaputirwa | Mabhandi ekupedzisira akabatanidzwa pamwe chete. | Mapaipi makuru (>4″); mashandisirwo emaindasitiri. | Yakasimba kwazvo uye inogona kushandiswa zvakanyanya. |
IyoVharuvhu yebhora yeTrue UnionKazhinji ndiyo yakanakisisa pane dzose dziri mbiri, ichipa kuchengetedzwa kweweld inonyungudutsa ine kushanda kwakanaka sevharuvhu ine shinda kana kuti flange.
Mhedziso
Vharuvhu yebhora ine shinda inoshandisa shinda dzesikuruu, seNPT standard, kuti zvive nyore kuisa. Kuti ubatanidze kuPVC, shandisa adapta ine glue-on nguva dzose, kana kusarudzasoketi or vharuvhu yemubatanidzwapachinzvimbo.
