Nokufaka - Iyini? izinhlobo valve

igama elithi "nokufakwa" ngokuvamile atholakala emibhalweni isakhiwo. Igama lesinye isizwe, futhi okuqukethwe semantic kungase kuphakame ukudideka phakathi kwabantu engayazi imininingwane uhlelo lwayo lokusebenza.

Nokufaka i-ukwakhiwa

Umqondo legatsha "ukuqinisa" zingahlukaniswa ngamaqembu amabili amakhulu yamanani - kwesakhiwo nakwezobuchwepheshe.

Okokuqala elisetshenziswa wokwakha izakhiwo. ngokhonkolo njalo nakakhulu lihlukile dwala usebenzisa umthwalo elula nithela izinduku, grid noma ezineka ezingodweni.

Ama-valve, efakwe yamapayipi, ihambisa futhi ilawula notshwala uketshezi kule amanethiwekhi amanzi kanye indle. Sihlanganisa le miqondo ukusebenza. Nokufaka - lokhu yikho okwenza ingxenye ukusebenza kohlelo jikelele.

ukuqinisa kwesakhiwo

izakhiwo zikakhonkolo yinhlobo main imikhiqizo wokwakha. Ukhonkolo ngezinye izikhathi ibizwa ngokuthi itshe yokufakelwa. It has ukumelana enhle kakhulu kokucindezelwa, kodwa uma kuqhathaniswa ngobugebengu kalula ngaphansi ukungezwani futhi eguqa. Lokhu ethile siqedwa afanayo ukhonkolo ukuqinisa izinto kokuba ikhono ukuthatha imithwalo eqine ngaphandle kokulahleka kwamandla. ukuthuthukiswa Progressive we zokwakha umkhakha yandile ulayini nokufakwa izipesheli. Ngaphezu steel ezivamile, ifakwe polymer umkhiqizo, okuyinto ukuqinisa oluyinhlanganisela. Ukufika kombuso izinto ezintsha evumela ukuthatha ngokugcwele ku-akhawunti ukusebenza imikhiqizo.

Amazinga ukuqinisa kwesakhiwo

Ukusetshenziswa izinto kanye nemikhiqizo ukuze kwakhiwe izakhiwo kanye nezinhlaka akuvunyelwe ezilawulwayo. ukusebenza Safe kudinga ukuhambisana namazinga akhiwa ochwepheshe futhi ivunyelwe ezingeni komthetho. Steel ukuqinisa kufanele athobele GOST 10884-94, kulawulwa nemingcele ngokomzimba futhi lobuchwepheshe material. Composite ihambisana nezidingo GOST 31938-2012. Steel ukuqinisa abasathomako, ngokujwayelekile phakathi sebhithi ngoba ine isizinda esungulwe ezimbonini kanye namasiko kwezobuchwepheshe. Ngeshwa, izakhi esakhiwe ngezinto polymeric kungase kudingeke eside ukushintshashintsha umthengi izakhiwo okudinga ukunakekela ngokucophelela ukuze imikhiqizo ethengiwe. Kulokhu, okuthandayo kufanele inikwe amabhizinisi, ukuhlinzeka izici egcwele kubo.

steel ukuqinisa

Steel, okuyinto ekhiqizwa kusuka armature (GOST 10884-94) carbon and ingxubevange ongaphakeme. Ukuze uthuthukise adhesion emzimbeni obuphathekayo izinduku okungenzeka unayo iphrofayela gqwa, nemingcele zazo elicacisiwe isimo ejwayelekile. Lolu hlobo ukuqinisa ivamile kanti kahle wafunda. Steel ukuqinisa - uhlobo bendabuko amaphuzu ukuqinisa. Ngokhonkolo njalo nakakhulu ngezinduku steel, ezinkanjini namanetha, eyaziwa ngokuthi ngokhonkolo njalo nakakhulu. Kusukela ke kwenziwa cishe zonke izakhiwo, kusukela esisekelweni kuze kube panel soffit nasekusekeleni izakhi yokwakha ozimele. Lesi sitshalo ukhiqiza ibanga elikhulu kwagcizelela izakhiwo zikakhonkolo izinjongo ezihlukahlukene. Namuhla kakhudlwana futhi uzuza kakhulu avuke isakhiwo, lapho iningi izakhi isakhiwo Senziwe isikhundla design ngokuqondileyo ngokuthela ukhonkolo ngaphakathi shuttering livulwa yezinyoni ukuqinisa. Uma eyakha izakhi eziyisisekelo inqubo kunenze nisondelane is Welding izinduku, lapho yokukhiqiza endaweni evame ukusetshenziswa esibophezelayo ukuqinisa ngocingo. Ngaphezu gqwa iphrofayela ukuqinisa, futhi sisetshenziswa izinduku bushelelezi. amandla abo adhesion nge ukhonkolo noma nosimende kakhulu ephansi, kodwa kwezinye izimo ukusetshenziswa ukuqinisa gladkokatanoy kuthethelelwe.

ukhonkolo rebar esiyinhlanganisela

ukwakhiwa Modern liyasondela ngaphezulu imiva lathumela, futhi banciphise izindleko. I nokufakwa polymer kukuvumela ukwenza ngempumelelo. Inzuzo ebalulekile polymers kuqhathaniswa metal kuyinto isisindo aphansi kanye ukumelana ukugqwala. Lezi zihlanganisa i-basalt, carbon fibre, fiberglass rebar.

Amandla izakhiwo ngokuvamile idlule polymeric amakhono ukuqinisa steel. Thanda steel, ukuqinisa esiyinhlanganisela kungaba gqwa sephrofayela njalo. Nokho, umsebenzi wayo umthwalo has izici zayo siqu. Ngokungafani steel, fiberglass ukuqinisa akusho flow, futhi lapho esiphezulu imithwalo avumelekile imbubhiso leso timphawu.

Steel esiyinhlanganisela ngokumelene: yini ukukhetha?

Uhlamvu umsebenzi ukhonkolo kusikisela ukuthi kungenzeka umswakama valve ngesikhathi imifantu ukuvulwa izihloko usebenza eguqa futhi ngilulekela. Njengoba ungacabanga, lokhu kwandisa ingozi siphelelwe amandla kunciphisa ukuphila inkonzo izakhiwo. Lapho concreting noma wokwakha ebusika steel asitholayo isinyathelo nolaka frost izithasiselo, nakho kudala amathuba ukusebenza kwehle. izinto Polymeric ukuvumela ukugwema imiphumela emibi ukugqwala phezu izakhi eziveza kwezakhiwo kanjalo nezinhlaka. ukuqinisa Zokwenziwa esinikezayo. Nokho, inhlanganisela ibe izinkomba okubi kakhulu ngomlilo, ngokushesha ukulahlekelwa amandla lapho sishiswa ngakho. Okuncane valve isisindo esiyinhlanganisela kuyinto impahla ezikhangayo nomuntu futhi ephansi liphumele izakhiwo, njengoba umthetho, kungukuthi kuvikelwe kokusiphakamisela imishini. Encishisiwe zokuthutha izindleko nokunyakaza esakhiweni kungaba lemali eziphathekayo.

iphayiphi izesekeli

Ububanzi kwesicelo ukuqinisa ukuze amapayipi sihlanganise indawo ebanzi kakhulu. Isetshenziselwa yonke indawo kusukela komncane-ubukhulu amanethiwekhi ezizimele kuze imikhiqizo omkhulu ezimbonini. Pipeline valve ku amanethiwekhi ukusatshalaliswa edingekayo ukuhlangabezana nezindinganiso eziphakeme zokuphepha nokwethembeka wokusebenza. Lezi zici inethiwekhi, ngokuhlanganisa nezimfuneko eziphikisa kungaba ukumisa eziyinkimbinkimbi kakhulu. Ngokwesibonelo, ama-valve kumelwe ukumelana ukushaqeka hydrodynamic, kube eningi yezindleko ipayipi diameters ezinkulu. Ngakho-ke, i-material ofanele kakhulu ngokuvamile zibhekwa izinsimbi non-ayoni ezifana nethusi lethusi, okuvumela ukukhiqiza izihloko nepepper futhi ukubunjwa yinkimbinkimbi nelula. Nokho, banalo zibiza ukuqina ongaphakeme. Ngakho-ke, steel isetshenziswa, yensimbi kanye polymers njengoba izinto okwenziwa ngazo ukuqinisa ikhiqizwa. Umenzi iqinisekisa nemingcele yokusebenza imikhiqizo elikuvumela ukuba wenze isinqumo esisekelwe unolwazi elinama ethile.

Nokunye okuningi kumanethiwekhi sanitary

Ukusatshalaliswa plastic ipayipi nokufakwa anikeza ugqozi ukuvela kwezindaba plastic noma nge esibalulekile izingxenye plastic. Ethandwa kakhulu abaphikisi bangamalungu nezinsiza zomphakathi kanye nezinhlaka ezizimele. Inzuzo elingenakuphikwa emimoya amadivayisi esinjalo, kuba isisindo kancane futhi ukungabi khona ukugqwala amapayipi namanethiwekhi izakhi. Inqawe materials polymeric kungaba ubude cishe angenamkhawulo, ngokungafani kuya ngosayizi ojwayelekile metal. Ziyakwazi kulula sasivumela ukuba uxhumane nomunye ngezindlela ezihlukahlukene.

Welding polymers kancane kukhathaza engangenwa umlilo, uma kuqhathaniswa nabangu-Welding metal. Ngaphandle ukuntuleka ukugqwala, polymer amapayipi kanye nokufakwa awekho ngaphansi ekuqongeleleni amanzi Ukushisa amanethiwekhi kwezulu okungaholela overgrowing isikhala elingaphakathi ukunciphisa ubukhulu ngempumelelo. Misa valve, ukusatshalaliswa kanye neminye ogibele piping by ezisetshenzisiwe apharathasi pipe amalunga omzimba.
