Kusarudza mhando yeshinda isiriyo yePVC fittings yako kunotungamira mukubuda kwemvura kunonetsa. Kubuda kwemvura uku kunokonzera kukuvara kwemvura, kunonoka kweprojekiti, uye kunokumanikidza kuti uitezve basa, zvichikutorera nguva nemari.

NPT neBSPT zviyero zviviri zvakasiyana zvisingaenderane. NPT chiyero chekuAmerica chine kona yeshinda ye60°. BSPT chiyero chekuBritain chine kona yeshinda ye55°. Unofanira kufananidza rudzi rweshinda nepombi yako.

Iyi inyaya yandinowanzo kurukura nemumwe wangu Budi kuIndonesia. Mukutengeserana kwenyika, zvinhu zvidiki zvakaita semitemo yeshindazvinogona kuita mutsauko mukuru. Musika wekuSoutheast Asia dzimwe nguva unoshandisa mwero weAmerican ANSI, unosanganisira NPT, kunyanya kumapurojekiti chaiwo.

Ngationei kuti chii chinovasiyanisa nevamwe.

Ndeupi musiyano chaiwo uripo pakati peBSPT neNPT threads?

Tambo dziri pazvibatiso zviviri dzinoita sedzakafanana. Kukanganisa nekufunga kuti dzakafanana kunogona kubvisa tambo dzacho nekukanganisa chibatiso chacho, zvichiita kuti pave nechimwe chinotsiva.

Musiyano mukuru ndewekona yeshinda uye pitch. NPT threads dzine angle ye60-degree, nepo BSPT threads dzine angle ye55-degree. Musiyano mudiki uyu unodzidzivirira kubva pakuumba chisimbiso chakakodzera, chakachengeteka pamwe chete.

Pakutanga, ungasaona musiyano. Asi mainjiniya ari shure kwavo akasiyana zvachose.

NPT kana BSP ndiyo shinda iri nani here?

Unoda kuunganidza mhando yepamusoro uye inobatsira yemidziyo yekubatanidza zvinhu. Kuunganidza zvinhu zvisina kunaka pamusika wako kuchaita kuti zvinhu zvako zvifambe zvishoma nezvishoma uye vatengi vako vasafare.

Hapana imwe yemhando yepamusoro iri nani pane imwe; asi yakasiyana chete. Sarudzo yakanakisisa ndiyo iri mumhando yepamusoro munharaunda yako uye inoenderana nemichina iri kushandiswa nevatengi vako.

Iyi inyaya yenzvimbo, kwete mhando. NPT ndiyo nzira inonyanya kushandiswa muUnited States neCanada. Kana uri kushanda papurojekiti yakagadzirwa nekambani yekuAmerica kana kushandisa michina yekuAmerica, zvechokwadi uchadaZvishandiso zveNPT. Kune rumwe rutivi, BSP ndiyo mwero unoshandiswa munzvimbo zhinji dzepasi rose, kusanganisira Europe, UK, Asia, Australia, neSouth Africa. Pamusika weBudi muSoutheast Asia, unogona kusanganiswa. Ndinoziva kuti mapurojekiti mazhinji emuno neeEurope anoda BSPT. Zvisinei, mapurojekiti ane mari yekudyara kana mainjiniya ekuAmerica anowanzo tsanangura mwero weANSI, zvichireva NPT. Vharuvhu "yakanakisa" ndiyo inopinza zvakanaka mupombi yemutengi wako. Ndosaka zvichikosha kubvunza uye kusimbisa kuti ndeipi mwero inodiwa papurojekiti yega yega.

Matambo eNPT anowanikwawo pazvigadziko zvePVC here?

Uri kuodha mavharuvhu ebhora ePVC uye unofanira kusarudza rudzi rweshinda. Unofanira kuziva kana zvigadziko zvepurasitiki zvichigona kugadzirwa neshinda idzi dzesimbi.

Ehe, zvigadziko zvePVC zvinowanzogadzirwa neshinda dzeNPT neBSP. Izvi zvinobvumira masisitimu epurasitiki ekubatanidza zviri nyore nemapombi esimbi ane shinda, mapombi, nezvimwe zvikamu zvepombi zvakajairika.

KuPntek, tinogadzira mhando dzakasiyana-siyana dzePVC fittings dzine NPT neBSP threads kuti dzibatsire vadyidzani vedu vepasi rose. Kubatanidza thread inzira yakajairika yekugadzira kubatana kunogona kubatanidzwa nekubviswa. Zvisinei, zvakakosha kufunga nezvesimba repurasitiki. Maitiro ekucheka threads anobvisa zvinhu uye anogadzira poindi yekushushikana. Nekuda kwechikonzero ichi, tinogara tichikurudzira kushandisa madziro akakora.Purogiramu 80 PVCyekubatana kwakabatana, kunyanya mumasisitimu ane kumanikidzwa kwakanyanya kana kumanikidzwa kwemuchina. Kunyange zvazvo uchigona kupinza mapaipi nemidziyo yeSchedule 40, kugona kwavo kubata kumanikidzwa kunoderedzwa zvakanyanya. Kushandisa PVC fitting yakagadzirwa nefekitori kunogara kwakavimbika kupfuura kucheka shinda kuita pombi isina chinhu iwe pachako.

Unogona kubatanidza BSPT neNPT threads pamwe chete here?

Une chibatiso cheNPT chechikadzi uye pombi yeBSPT yechirume mumunda. Zvinoita sekunge inogona kuvhiringika, uye unoedzwa kuimanikidza kuti ipedze basa racho.

Kwete, haufanirwe kumbobatanidza shinda dzeBSPT neNPT zvakananga. Makona asina kuenzana achaita kuti dzisunge, dzibatanidze shinda, uye dzikuvadze zvinobatanidzwa. Izvi zvinogadzira jointi isina kusimba iyo inovimbiswa kuti ichabuda mvura.

Kuedza kumanikidza mitemo iyi miviri pamwe chete inzira yekukundikana. Nekuti makona eshinda nepitches zvakasiyana, hazvigone kusungirirwa zvakanaka. Chinoitika inzira inonzi "kubatanidza tambo,” apo chikamu chepamusoro cheshinda imwe chinocheka mumudzi weimwe panzvimbo pekugara zvakanaka. Izvi zvinokuvadza zvachose shinda dzechirume nedzechikadzi. Kunyangwe ukashandisa tepi yakawanda yekuvhara shinda, haizozadzi mipata inogadzirwa nejometri isina kuenderana. Kubatana kuchabuda kana sisitimu yaiswa pasi pekumanikidzwa. Nzira chete chaiyo uye yehunyanzvi yekubatanidzaSisitimu yeBSPT kuenda kuNPT systemIzvi zvinoitwa nekushandisa adapter fitting yakakosha. Adapter idzi dzinogadzirwa neshinda dzechikadzi nedzechirume dzakakodzera pamativi akasiyana kuti dzigadzire shanduko yakachengeteka, isingadonhedze mvura.

Mhedziso

NPT neBSPT zviyero zvakasiyana, hazvienderane. Sarudzo chaiyo inoenderana nenzvimbo yepurojekiti yako uye zvakatemwa. Gara uchisimbisa chiyero chinodiwa kuti uve nechokwadi chekubatana kwakachengeteka, kwakavimbika, uye kusina kudonhedza mvura kwezvishandiso zvako zvePVC.
