Waraira rori remavharuvhu epurojekiti hombe. Asi kana vasvika, tambo hadzienderane nepombi dzako, zvichikonzera kunonoka kukuru uye kudzoka kunodhura.

Mhando mbiri huru dzetambo dzevharuvhu iNPT (National Pipe Taper) inoshandiswa kuNorth America, uye BSP (British Standard Pipe), inowanikwa kwese kwese. Kuziva kuti ndeipi dunhu rako rinoshandisa ndiro danho rekutanga kune leak-proof yekubatanidza.

Kuwana mhando yeshinda chaiyo ndechimwe chezvinhu zvakakosha, asi zvakakosha, zvikamu zvekutsvaga. Ndakamboshanda naBudi, maneja wekutenga muIndonesia, uyo netsaona akaodha mudziyo wemavharuvhu ane shinda dzeNPT pachinzvimbo cheBSP chiyeroinoshandiswa munyika yake. Yakanga iri mhosho yakareruka yakakonzera kutema kukuru kwemusoro. Shinda dzinotaridzika zvakafanana, asi hadzienderane uye dzinodonha. Kupfuura tambo, kune mamwe marudzi ekubatanidza senge socket uye flange inogadzirisa matambudziko akasiyana. Ngative nechokwadi chekuti unokwanisa kuvasiyanisa vese.

Chii chinorehwa neNPT pavharuvhu yebhora?

Iwe unoona "NPT" pane imwe pepa uye unofunga kuti ingori shinda yakajairwa. Kuregeredza ruzivo urwu kunogona kutungamira kune zvinongedzo zvinoita sedzakasimba asi dzinodonha pasi pekumanikidzwa.

NPT inomirayeNational Pipe Taper. Izwi rakakosha ndere "taper". Shinda dzacho dzine makona zvishoma, saka dzinobatana pamwe chete paunenge uchidzisunga kuti dzigadzire chisimbiso chakasimba chemagetsi.

Iyo tapered dhizaini ndicho chakavanzika kuseri kweNPT yekuisa chisimbiso simba. Semurume NPT yakarukwa pombi masiruu mukati meNPT yemukadzi inokwana, dhayamita yezvikamu zvese zvinoshanduka. Kupindira uku kunopwanya shinda pamwe chete, kuita chisimbiso chekutanga. Nekudaro, iyi simbi-pa-simbi kana yepurasitiki-pa-plastiki deformation haina kukwana. Pane nguva dzose madiki anotenderera asara. Ndokusaka uchifanira kushandisa tambo sealant, senge PTFE tepi kana pombi dope, ine NPT zvinongedzo. Iyo sealant inozadza aya madiki madiki gap kuita kuti chinongedzo chinyatso kuvuza-chiratidzo. Iyi chiyero chakanyanya muUnited States neCanada. Kune vatengi vekunze vakaita seBudi, zvakakosha kuti utaure "NPT" chete kana vaine chokwadi chekuti chirongwa chavo chinochida; kana zvisina kudaro, ivo vanoda BSP yakajairwa muAsia neEurope.

Ndeapi marudzi akasiyana ekubatanidza mavharuvhu?

Iwe unoda kubatanidza valve kune pombi. Asi iwe unoona sarudzo dze "shinda," "socket," uye "flanged," uye hauzive kuti ndeipi yakakodzera basa rako.

Marudzi matatu makuru ekubatanidza mavharuvhu akaiswa shinda yepombi dzakarukwa, soketi yepombi dzakanamwa dzePVC, uye dzakachinjika kune hombe, dzakasungwa pombi masisitimu. Imwe neimwe yakagadzirirwa imwe yakasiyana pombi zvinhu, saizi, uye inoda kugadzirisa.

Kusarudza mhando yekubatanidza yakakodzera kwakangokosha sekusarudza vharafu chaiyo. Hazvichinjike. Chimwe nechimwe chine chinangwa chakasiyana uye chinokodzera kushandiswa kwakasiyana. Funga nezvavo senzira dzakasiyana dzekubatanidza mugwagwa.Zvisungo zvakabatanidzwavakaita semharadzano yakajairika,socket connectionsakaita semusanganiswa wechigarire apo migwagwa miviri inova imwe, uye mibatanidzwa ine mitsetse yakafanana nechikamu chebhiriji chinogona kuchinjika nyore nyore. Ini ndinogara ndichiraira timu yaBudi kutungamira vatengi vavo zvichienderana neremangwana rehurongwa hwavo. Iri tambo yekudiridza inogara isingachinji? Shandisa socket weld. Icho chinongedzo kune pombi ingangoda kutsiviwa? Shandisa tambo ine shinda kana kuti flanged valve kuti ibvise nyore.

Main Valve Connection Types

Ndeapi marudzi mana emavharuvhu ebhora?

Unonzwa vanhu vachitaura nezve "chimwe-chidimbu," "mbiri-chidimbu," kana "matatu-chidimbu" mavharuvhu. Izvi zvinonzwika kuvhiringa uye unonetsekana kuti uri kutenga isiriyo kune yako bhajeti uye kugadzirisa zvinodiwa.

Mavharuvhu ebhora anowanzo kupatsanurwa nekuvakwa kwemuviri wavo: One-Piece (kana Compact), Mbiri-Piece, uye Three-Piece. Aya madhizaini anosarudza mutengo wevharuvhu uye kana inogona kugadzirwa.

Nepo vanhu dzimwe nguva vachitaura marudzi mana, matatu makuru ekuvaka masitayipi anovhara anenge ese maapplication. A"One-Piece" valve, inowanzonzi Compact valve, ine muviri wakagadzirwa nechidimbu chimwe chepurasitiki yakaumbwa. Bhora rakavharirwa mukati, saka harigoni kuparadzaniswa kuti rigadziriswe. Izvi zvinoita kuti ive sarudzo yakachipa, asi inonyanya kuraswa. Vhuru ye "Two-Piece" ine muviri wakagadzirwa nemativi maviri anokochekera pamwe chete kutenderedza bhora. Iyi ndiyo mhando yakajairika. Inogona kubviswa kubva papombi uye kuparadzaniswa kuti itsive zvisimbiso zvemukati, ichipa chiyero chakanaka chemutengo uye kushanda. Ivhavha ye "Three-Piece" ndiyo inonyanya kufambira mberi. Iine muviri wepakati une bhora, uye maviri akapatsanurwa ekupedzisira ekubatanidza. Iyi dhizaini inokubvumira kuti ubvise muviri mukuru wekugadzirisa kana kutsiva pasina kucheka pombi. Ndiyo inodhura zvakanyanya asi yakanakira mitsara yefekitori kwausingakwanise kuvharika kwenguva refu kugadzirisa.

Ndeupi musiyano uripo pakati peNPT uye flange yekubatanidza?

Uri kugadzira sisitimu uye unoda kusarudza pakati pemavharuvhu ane threaded kana flanged. Kuita kufona kusiri iko kunogona kuita kuti kuisirwa kuve dambudziko uye kugadzirisa kudhura zvakanyanya munzira.

NPT yekubatanidza yakarukwa uye yakanakira mapaipi madiki, ichigadzira yekusingaperi-style yekubatanidza iyo inonetsa kushanda. Flange yekubatanidza inoshandisa mabhaudhi uye yakanakira pombi hombe, ichibvumira kubviswa kwevharuvhu kuri nyore kugadzirisa.

Sarudzo pakati peNPT neflange inonyatso kudzika kuzvinhu zvitatu: saizi yepombi, kudzvanywa, uye kugadzirisa zvinodiwa. Tambo dzeNPT dzakanakira mapaipi madiki dhayamita, anowanzo 4 inches uye pasi. Iyo inodhura-inoshanda uye inogadzira yakasimba kwazvo, yakakwira-kudzvanywa chisimbiso kana yaiswa nemazvo ine sealant. Dambudziko ravo guru nderokuchengetedza. Kuti utsive valve yakasungirirwa, iwe kazhinji unofanirwa kucheka pombi. Flanges ndiyo mhinduro yemapombi akakura uye kune chero hurongwa uko kuchengetedza kuri pamberi. Kuvhara vharafu pakati pemaflange maviri kunobvumira kuti ibviswe uye kutsiviwa nekukurumidza pasina kukanganisa pombi. Ichi ndicho chikonzero vatengi veBudi's kontrakta vanovaka mahombe ekuchenesa mvura anenge achingoda kuodha mavharuvhu. Vanodhura zvakanyanya kumberi, asi vanochengetedza yakawanda yenguva uye basa panguva yekugadzirisa mune ramangwana.

NPT vs. Flange Kuenzanisa

Mhedziso

Kusarudza shinda chaiyo kana kubatanidza—NPT, BSP, socket, kana flange—ndiro danho rinokosha zvikuru pakuvaka gadziriro yakachengeteka, inodonhedza uye kuona kuchengetedzwa kuri nyore kweramangwana.
