Wategetse ikamyo yikamyo kumushinga munini. Ariko iyo zihageze, insanganyamatsiko ntizihuza imiyoboro yawe, itera gutinda cyane no kugaruka bihenze.

Ubwoko bubiri bwingenzi bwimipira ya valve ni NPT (National Pipe Taper) ikoreshwa muri Amerika ya ruguru, na BSP (British Standard Pipe), isanzwe ahandi hose. Kumenya akarere kawe gakoresha nintambwe yambere yo guhuza amakuru.

Kubona ubwoko bwurudodo iburyo nimwe mubyingenzi, nyamara binenga, ibice byo gushakisha. Nigeze gukorana na Budi, umuyobozi ushinzwe kugura muri Indoneziya, wategetse ku bw'impanuka ikintu cya valve gifite insinga za NPT aho kubaBSPyakoreshejwe mu gihugu cye. Byari ikosa ryoroshye ryateye umutwe munini. Urudodo rusa, ariko ntiruhuza kandi ruzatemba. Kurenga kumutwe, hariho ubundi bwoko bwihuza nka sock na flange bikemura ibibazo bitandukanye. Reka tumenye neza ko ushobora kubabwira bose.

NPT isobanura iki kuri valve yumupira?

Urabona "NPT" kurupapuro rwihariye hanyuma ukeka ko ari urudodo rusanzwe. Kwirengagiza ibi bisobanuro birashobora kuganisha kumihuza isa nkiyoroshye ariko igatemba mukibazo.

NPT ihagazeya Tipe y'igihugu. Ijambo ryibanze ni "taper." Utudodo dufite inguni nkeya, nuko zuzuzanya nkuko ubiziritse kugirango ukore kashe ikomeye ya mashini.

Igishushanyo cyafashwe ni ibanga ryihishe inyuma ya NPT. Nkumugabo NPT wapanze umuyoboro winjiza mumugore NPT ukwiranye, diameter yibice byombi irahinduka. Uku kwivanga gukwiranye gusya hamwe, gukora kashe yibanze. Nyamara, iki cyuma-cyuma cyangwa plastiki-kuri-plastiki ihindagurika ntabwo itunganye. Hama hariho utuzu duto twa spiral. Niyo mpamvu ugomba guhora ukoresha urudodo rudodo, nka kaseti ya PTFE cyangwa dope, hamwe na NPT. Ikidodo cyuzuza ibyo byuho bya microscopique kugirango bihuze rwose. Ibipimo byiganje muri Amerika na Kanada. Ku baguzi mpuzamahanga nka Budi, ni ngombwa kwerekana "NPT" gusa mugihe bazi neza ko umushinga wabo ubisaba; bitabaye ibyo, bakeneye BSP isanzwe muri Aziya no muburayi.

Ni ubuhe bwoko butandukanye bwo guhuza valve?

Ugomba guhuza valve kumuyoboro. Ariko urabona amahitamo ya "urudodo," "sock," na "flanged," kandi ntumenye neza igikwiye kumurimo wawe.

Ubwoko butatu bwingenzi bwihuza bwa valve buhujwe nu miyoboro isunitswe, sock ya miyoboro ya PVC yometse, kandi ihindagurika kuri sisitemu nini, ihindagurika. Buri kimwe cyagenewe ibikoresho bitandukanye, ubunini, nibikenewe kubungabungwa.

Guhitamo uburyo bwiza bwo guhuza ni ngombwa kimwe no guhitamo valve iburyo. Ntibishobora guhinduka. Buri kimwe gikora intego zitandukanye kandi gikwiranye nibisabwa bitandukanye. Tekereza nk'inzira zitandukanye zo guhuza umuhanda.Ihurironi nk'isangano risanzwe,ihurironi nkibihuru bihoraho aho imihanda ibiri ihinduka imwe, kandi guhuza guhuza ni nkigice cyikiraro gishobora guhinduka byoroshye. Buri gihe ndagira inama itsinda rya Budi kuyobora abakiriya babo nkurikije ejo hazaza ha sisitemu. Numurongo wo kuhira uhoraho utazigera uhinduka? Koresha sock weld. Nibihuza pompe ishobora gukenera gusimburwa? Koresha valve ifite umugozi cyangwa flanged kugirango ukureho byoroshye.

Ubwoko Bukuru Bwihuza Ubwoko

Ni ubuhe bwoko bune bw'imipira?

Urumva abantu bavuga kubyerekeye "igice kimwe," "ibice bibiri," cyangwa "ibice bitatu". Ibi bisa nkaho bitesha umutwe kandi ufite impungenge ko ugura ibitari byiza kuri bije yawe no kubikenera.

Imipira yumupira ikunze gushyirwa mubikorwa nubwubatsi bwumubiri wabo: Igice kimwe (cyangwa Compact), Ibice bibiri, na Bitatu. Ibishushanyo byerekana igiciro cya valve niba ishobora gusanwa.

Mugihe abantu rimwe na rimwe bavuga ubwoko bune, uburyo butatu bwubwubatsi bukubiyemo hafi ya porogaramu zose. A.“Igice kimwe”, bakunze kwita Compact valve, ifite umubiri wakozwe mubice bimwe bya plastiki yabumbwe. Umupira ufunzwe imbere, ntushobora gutandukana kugirango usanwe. Ibi bituma ihitamo bihendutse, ariko birashoboka cyane. Umuyoboro wa “Two-Piece” ufite umubiri ugizwe n'ibice bibiri bizunguruka hamwe umupira. Ubu ni ubwoko busanzwe. Irashobora gukurwa kumuyoboro hanyuma igatandukanwa kugirango isimbuze kashe yimbere, itanga impagarike nziza yikiguzi na serivisi. Umuyoboro wa “Three-Piece” niyo wateye imbere cyane. Ifite umubiri wo hagati urimo umupira, hamwe nibihuza bibiri bitandukanye. Igishushanyo kigufasha gukuramo umubiri wingenzi kugirango usane cyangwa usimburwe udatemye umuyoboro. Nibihe bihenze cyane ariko nibyiza kumurongo wuruganda aho udashobora kwigurira igihe kirekire kugirango ubungabunge.

Ni irihe tandukaniro riri hagati ya NPT na flange ihuza?

Urimo gukora sisitemu kandi ukeneye guhitamo hagati yimigozi cyangwa ingirakamaro. Guhamagara nabi birashobora gutuma kwishyiriraho inzozi no kubungabunga bihenze cyane mumuhanda.

Ihuriro rya NPT rifite urudodo kandi rwiza kumiyoboro mito, kurema uburyo buhoraho-buhuza bigoye kuri serivisi. Flange ihuza ikoresha bolts kandi nibyiza kumiyoboro minini, ituma kuvanaho byoroshye byoroshye kubungabunga.

Guhitamo hagati ya NPT na flange rwose biza mubintu bitatu: ubunini bwumuyoboro, igitutu, nibikenewe byo kubungabunga. Urudodo rwa NPT ni rwiza ku miyoboro ntoya ya diameter, mubisanzwe santimetero 4 no munsi. Birahenze kandi birema kashe ikomeye cyane, yumuvuduko mwinshi iyo ushyizweho neza hamwe na kashe. Ingaruka zabo nini ni ukubungabunga. Kugirango usimbuze valve ifite urudodo, akenshi ugomba guca umuyoboro. Flanges nigisubizo kumiyoboro minini no kuri sisitemu iyo ari yo yose aho kubungabunga ari byo byihutirwa. Guhindura valve hagati ya flanges ebyiri bituma ikurwaho kandi igasimburwa vuba bitabangamiye imiyoboro. Niyo mpanvu abakiriya ba rwiyemezamirimo Budi bubaka inganda nini zitunganya amazi hafi ya zose zitumiza indangagaciro. Bitwara byinshi imbere, ariko bizigama umwanya munini nakazi mugihe cyo gusana ejo hazaza.

NPT na Flange Kugereranya

Umwanzuro

Guhitamo urudodo rwukuri cyangwa ihuza-NPT, BSP, sock, cyangwa flange - nintambwe yingenzi cyane yo kubaka sisitemu itekanye, idashobora kumeneka no kubungabunga byoroshye ejo hazaza.
