Watenga mavharuvhu akawanda ebasa guru. Asi paanosvika, mavharuvhu acho haaenderane nemapaipi ako, zvichikonzera kunonoka kukuru uye kudzoka kunodhura.

Mhando mbiri huru dzetambo dzemavharuvhu ebhora ndiNPT (National Pipe Taper) inoshandiswa kuNorth America, uye BSP (British Standard Pipe), inowanikwa kwese kwese. Kuziva kuti ndeipi inoshandiswa nedunhu rako ndiyo nhanho yekutanga yekubatanidza isingadonhedze mvura.

Kuwana mhando chaiyo yeshinda ndeimwe yezvinhu zviri nyore, asi zvakakosha, pakutsvaga. Ndakamboshanda naBudi, maneja wekutenga muIndonesia, uyo akaraira netsaona chirongo chemavharuvhu chine shinda dzeNPT panzvimbo peBSP standardyakashandiswa munyika make. Kwaive kukanganisa kuri nyore kwakakonzera musoro mukuru. Matambo acho akafanana, asi haaenderane uye anodonhedza mvura. Kunze kwetambo, kune dzimwe mhando dzekubatanidza dzakadai sesoketi neflange dzinogadzirisa matambudziko akasiyana. Ngativei nechokwadi chekuti munogona kuasiyanisa ese.

Chii chinonzi NPT pavharuvhu yebhora?

Unoona "NPT" pane spec sheet wobva wafunga kuti ingori thread yakajairika. Kusateerera ruzivo urwu kunogona kutungamira kune zvinobatanidzwa zvinoita sekunge zvakamanikana asi zvichibuda kana zvamanikidzwa.

NPT zvigadzikoyeNational Pipe Taper. Shoko guru nderekuti “taper.” Tambo dzacho dzakakombama zvishoma, saka dzinobatana kana uchidzisimbisa kuti dzigadzire chisimbiso chakasimba chemuchina.

Dhizaini yakatetepa ndiyo chakavanzika chesimba rekuvhara reNPT. Sezvo pombi yemurume yeNPT yakarukwa ichipinda muNPT yemukadzi, dhayamita yezvikamu zvese zviri zviviri inochinja. Kupindirana uku kunopwanya tambo pamwe chete, zvichiita chisimbiso chekutanga. Zvisinei, kuchinja uku kwesimbi-pane-simbi kana purasitiki-pane-purasitiki hakuna kukwana. Nguva dzose pane mipata midiki inosara. Ndosaka uchifanira kushandisa chisimbiso cheshinda, senge PTFE tepi kana pombi dope, ine NPT connections. Chisimbiso chinozadza mipata iyi midiki kuti kubatana kurambe kuchidzivirira kubuda kwemvura. Iyi standard ndiyo inonyanya kushandiswa muUnited States neCanada. Kune vatengi vekunze vakaita seBudi, zvakakosha kudoma "NPT" chete kana vaine chokwadi chekuti purojekiti yavo inoda izvozvo; zvikasadaro, vanoda BSP standard inowanikwa muAsia neEurope.

Ndedzipi mhando dzakasiyana dzekubatanidza mavharuvhu?

Unofanira kubatanidza vharuvhu papombi. Asi unoona sarudzo dze "threaded," "socket," uye "flanged," uye hauzive kuti ndeipi yakakodzera basa rako.

Mhando nhatu huru dzekubatanidza mavharuvhu dzinoshandiswa pakubatanidza mapaipi ane screws, socket yemapaipi ePVC ane glue, uye flanged yemasisitimu emapaipi makuru ane bholiti. Imwe neimwe yakagadzirirwa zvinhu zvakasiyana zvepaipi, saizi, uye kudiwa kwekugadzirisa.

Kusarudza rudzi rwekubatanidza rwakakodzera kwakakosha sekusarudza vharuvhu rakakodzera. Hazvichinjiki. Imwe neimwe ine basa rakasiyana uye yakakodzera mashandisirwo akasiyana. Funga nezvayo senzira dzakasiyana dzekubatanidza mugwagwa.Kubatana kwakabatanazvakafanana nenzvimbo yakajairwa inoungana,kubatana kwemasokisiZvakafanana nekubatana kwezvisingaperi uko migwagwa miviri inova imwe, uye zvinobatanidzwa zvine flange zvakafanana nechikamu chebhiriji rinochinjika rinogona kutsiviwa zviri nyore. Ndinogara ndichikurudzira timu yaBudi kuti itungamire vatengi vavo zvichienderana neramangwana rehurongwa hwavo. Mutsetse wekudiridza usingaperi hauzombochinjwa here? Shandisa socket weld. Kubatanidza pombi kungangoda kutsiviwa here? Shandisa vharuvhu ine tambo kana flange kuti zvive nyore kubvisa.

Mhando dzeKubatanidza Mavharuvhu Makuru

Ndeapi marudzi mana emavharuvhu ebhora?

Unonzwa vanhu vachitaura nezvemavharuvhu ekuti “one-piece,” “two-piece,” kana “three-piece”. Izvi zvinonzwika sekunge zvinovhiringidza uye unonetseka kuti uri kutenga isiriyo yakakodzera bhajeti rako uye zvinodiwa pakugadzirisa.

Mavharuvhu ebhora anowanzo kurongwa zvichienderana nekugadzirwa kwemuviri wavo: Chidimbu Chimwe (kana Chidiki), Chidimbu Chechipiri, uye Chidimbu Chetatu. Magadzirirwo aya anosarudza mutengo wevharuvhu uye kana ichigona kugadziriswa.

Kunyange zvazvo dzimwe nguva vanhu vachitaura nezvemhando ina, nzira nhatu huru dzekuvaka dzinobatanidza zvinenge zvese zvinoshandiswa.Vharuvhu ye "Chidimbu Chimwe", inowanzonzi vharuvhu diki, ine muviri wakagadzirwa nepurasitiki imwe chete yakaumbwa. Bhora racho rakavharirwa mukati, saka harigone kubviswa kuti rigadziriswe. Izvi zvinoita kuti rive sarudzo yakachipa, asi rinoraswa. Vharuvhu ye "Two-Piece" ine muviri wakagadzirwa nezvikamu zviviri zvinosunga pamwe chete zvakatenderedza bhora. Iyi ndiyo mhando inonyanya kushandiswa. Inogona kubviswa kubva papombi uye kubviswa kuti itsive zvisimbiso zvemukati, zvichipa mwero wakanaka wemutengo uye kushanda. Vharuvhu ye "Three-Piece" ndiyo yepamusoro-soro. Ine muviri wepakati une bhora, uye maviri akasiyana ekupedzisira ekubatanidza. Dhizaini iyi inokutendera kubvisa muviri mukuru kuti ugadziriswe kana kutsiviwa pasina kucheka pombi. Ndiyo inodhura zvakanyanya asi yakakodzera mitsetse yefekitori kwausingakwanise kubhadhara kudzima kwenguva refu kwekugadzirisa.

Ndeupi musiyano uripo pakati peNPT nekubatana kweflange?

Uri kugadzira sisitimu uye unofanira kusarudza pakati pemavharuvhu ane shinda kana kuti akaputirwa. Kuita ruzha rusina kunaka kunogona kuita kuti kuisa kwacho kuve kwakaoma uye kugadzirisa kudhura zvakanyanya.

Makochekedzo eNPT akagadzirwa neshinda uye akanakira mapaipi madiki, zvichiita kuti pave nekochekedzo inogara kwenguva refu iyo inonetsa kugadzirisa. Makochekedzo eFlange anoshandisa mabhoti uye akanakira mapaipi makuru, zvichiita kuti zvive nyore kubvisa mavharuvhu kuti agadziriswe.

Sarudzo pakati peNPT neflange inoenderana nezvinhu zvitatu: saizi yepombi, kudzvanywa, uye zvinodiwa pakugadzirisa. NPT threads dzakanaka kwazvo kumapombi madiki ane dhayamita, anowanzova masendimita 1.5 zvichidzika. Dzinodhura zvishoma uye dzinogadzira chisimbiso chakasimba, chine kudzvanywa kwepamusoro kana chakaiswa nemazvo nechisimbiso. Dambudziko radzo guru kugadzirisa. Kuti utsive vharuvhu ine shinda, unowanzo fanira kucheka pombi. Flanges ndiyo mhinduro yemapombi makuru uye kune chero sisitimu iyo kugadzirisa kuri chinhu chakakosha. Kusunga vharuvhu pakati peflanges mbiri kunoita kuti ibviswe uye itsiviwe nekukurumidza pasina kukanganisa pombi. Ndokusaka vatengi veBudi vanovaka nzvimbo huru dzekuchenesa mvura vanongoda chete mavharuvhu ane flanges. Anodhura zvakanyanya pakutanga, asi anochengetedza nguva yakawanda nebasa panguva yekugadzirisa mune ramangwana.

Kuenzanisa NPT vs. Flange

Mhedziso

Kusarudza shinda kana kubatana kwakakodzera—NPT, BSP, soketi, kana flange—ndiyo nhanho yakakosha pakuvaka sisitimu yakachengeteka, isingadonhedze mvura uye kuve nechokwadi chekuti kugadzirisa kuri nyore mune ramangwana.
