Kwesincane iphayiphi: amasu eziyisisekelo nezidingo zokuphepha

Cishe wonke umculi ebhekene isidingo tie ku emgqeni. Imisebenzi ubuchwepheshe kulokhu kuzoya kakhulu ngokuthi yikuphi impahla isetshenziswa iphayiphi. Okusetshenziswayo izinhlelo namuhla ababuthelwa kusukela cast iron, amapayipi lashukumisa and plastic, kodwa ngolwazi oluphelele kufanele kubhekwe uma zonke ubuchwepheshe. Asiqale incazelo imodi ngayinye.

Libhokisi nge ukuqinisa polymeric

Kwesincane ku iphayiphi kusukela polymers kuyoba ngokohlelo lweSitatimende ubuchwepheshe ethize. Isinyathelo sokuqala ukufinyelela umugqa ngokumba umumo emgodini square. Ubukhulu balo kufanele wenze 1,5x1,5 m. Imivubukulo kwenziwe lapho besanda kuqala ngosizo imishini ekhethekile. Kodwa uzobe kuphela azuzwe piping simiso strip metal, elisemnyango umugqa phezulu, kubalulekile ukusebenzisa lokwela izithathe ukuze ixazulule leyo asele 40 cm.

Uma ubona tube, ungakwazi uqhubekele amba umsele kuze kube isakhiwo. Lapho usuqedile nalokhu, kufanele uqale ukuhlomisa empompini. Ngenxa yale njongo, ezinjengenyanga ekhethekile, okuyizinto obizwa umhlengikazi. Lezo zinto egoqekayo futhi asetshenziselwa uthayi-amapayipi. Abakwazi kuqhathaniswa Tees, iqonde-ngokusebenzisa amapayipi ezithinta izingxenye ezimbili. On the imikhiqizo yepulasitiki ingafakwa izibopho olulodwa futhi Ukugunda. Nokho, option ezifanele kakhulu kungaba Izihlalo zamahhashi, ngenxa collar electric egoqekayo.

Uma kwenziwe komsele kwesincane kwalo buchwepheshe, a collar sibekwe phezu uthayi-iphuzu bese uxhuma nge electrofusion kulandzelana nekuhlunga tinsita. Uma idatha ukusebenza sezigcwalisekile, ezithela phezu kwalowaya mhlengikazi kufanele ifakwe komzimba ipayipi ezonikeza uxhumano futhi leakproofness okusezingeni eliphezulu.

Le ndlela yokwenza umsebenzi

Isinyathelo esilandelayo ukuze bayamba ipayipi kusukela umqhele sokuprakthiza noma ezivamile. Ithuluzi ubukhulu kufanele zibe zincane ziqhathaniswa ipharamitha eyinqaba Saddle umlomo wombhobho engenhla. Sokuprakthiza Kumelwe singene tube ngokusebenzisa shutoff valve tube ezedlulayo. Drilling Kwenziwa usebenzisa umlomo wombhobho ekhethekile, iqinisekisa yobunzima we ngokuhlanganyela.

Abanye onobuhle ukuphakamisa Saddles ukushumeka umqhele bezihlahla e amajika. Kufanele ajikelezwe usebenzisa ukhiye bifurcated. Ngesikhathi esigabeni sokugcina kuyodingeka babe ipayipi emseleni, yokuxhuma valve. Lisebenzisa emikhonweni crimp.

isazi izincomo

Lapho kwenziwe komsele kwesincane ubuchwepheshe ngenhla echazwe ingabekwa endaweni ukufakwa mgodi. Ngenxa yale njongo phansi emgodini ezijulile, ligcwele isihlabathi futhi amatshe, futhi ngemva iringi isethi, olokuqala okuzodingeka kunesikhala for ipayipi. Umcamelo egcwele kwagcizelela ukhonkolo, uma uthanda, ukushuba zazo kufanele kube-10 cm. Lokhu kuyadingeka ukuze isicelo uphawu M-150 noma M-200. Kubalulekile imenze zero ezingeni wesisekelo headroom kahle sunroof. Lo mklamo kusiza ukulungisa amanzi izinhlelo. Umthengi uzokwazi ukubhala ngaphezulu uhlelo usebenzisa valve emaphakathi.

I u we amapayipi metal

Uma une yensimbi amapayipi amapayipi, ubophele-kulo Kwenziwa nobunye ubuchwepheshe. Lokhu kungenxa yokuthi i-hardware kunokukwenza plastic, kodwa plasticity we indaba akuyona okusezingeni eliphezulu kangaka. Lokhu kubonisa ukuthi insimbi kungenzeka umane qhumisa.

Ngakho-ke, lapho tube kwesincane kumele bambe futhi bahlanza of nokugqwala endaweni lapho umsebenzi kuzokwenziwa. Ungqimba phezulu yensimbi ohlangene kumele ukusika besebenzisa grinder engela endaweni lapho ziyokhokhwa. Esikhathini isethi sehhashi tube, futhi uphawu iraba athambekele phakathi armature futhi ngokuqinisekile ijoka. Joint kumele uphawu.

Ubuchwepheshe umsebenzi

Uma une yensimbi amapayipi amapayipi, isinyathelo esilandelayo ukukhiya livaleke-off valve kuya flanged ekupheleni Saddles. Through the kuqala futhi sizoqala umqhele. Sakaza yensimbi ipayipi is yamba, nge isidingo kuphole endaweni umsebenzi futhi ushintshe ngezikhathi ezithile, bit kuhlulekile. Ngakho-ke kubalulekile ukusebenzisa osezingeni ithuluzi ekhethekile, okuyinto has a Carbide. cut impahla ngeke kwenzeke nezinye imishini. Ngesikhathi yokugcina umqhele esiteji isuswe, ukugeleza kwamanzi ivinjelwe, kanye ukufakwa umlenze yangaphandle wenziwa nezimiso ezijwayelekile.

Ukubeka mgodi endaweni uthayi

Lapho kwenziwe komsele kwesincane ingafakwa mgodi. Lesi senzo kuyinto efiselekayo, kodwa luqedwe. imikhiqizo Steel ring ukuqina akuzona wawungaphansi nokufakwa yensimbi, kodwa plastic ngaphezulu uma ziqhathaniswa cast iron. Lokhu kuchaza ukusetshenziswa ubuchwepheshe yokuqala, lapho kwesincane ibe steel pipe. Le nqubo sifana ezisetshenziswa imikhiqizo yepulasitiki.

Ukuhlelwa uthayi-e steel pipe kwenziwa ubuchwepheshe ethize. Ipayipi kufanele kucace, mahhala kusuka ukugqwala futhi ulungiselela umsebenzi. Umkhiqizo ashiselwe flanged tube kochungechunge eyehlayo kusukela ukuqinisa main. Ukuze ipayipi kuvunyelwe ukusebenzisa noma isiphi uhlobo ipayipi iphuma, into esemqoka ukuthi elele inhliziyo steel kwesakhiwo.

Kubalulekile ukukhumbula

Lapho kwenziwe kwesincane e okuwukuphela kwepayipi lamanzi, ngemva ukwakheka weld kufanele kuhlolelwe ukuzinza. Ingaphakathi is ugcobe nge iziketekete isikhala ngaphandle kuyadingeka ukumaka ngoshoki. Uma uyikha phezulu le yangaphandle kuyoba uwoyela amabala, okuzokwenza ukhulume izici esibonakalayo.

Izici imisebenzi

Uma kwenziwe wonke umsebenzi oye ezichazwe ngenhla, valve kochungechunge noma flanged zingaqiniswa kuya ingono. Leli payipi is yamba ngokusebenzisa valve futhi izingqimba engenhla kungenzeka sinqotshwe i sokuprakthiza kagesi. milimitha kwakamuva ungakwazi sokuprakthiza ngesandla. Ukuze umphini efakwe igatsha yangaphandle uhlelo kunomsele ezaholela endlini nge emseleni evulekile.

Lapho kwenziwe kwesincane e okuwukuphela kwepayipi lamanzi, ukuphambuka Saddles ipayipi legatsha yangaphandle kufanele kulingane 2 °, kodwa kudingekile ukuba ngithume ekhaya. Ngokushesha nje lapho igatsha zangaphandle uzokwazi ukuqoqa, kufanele kuhlolelwe ukuvuza. Umsele kufanele wangcwatshwa endaweni lapho kuyiswe ibha eseceleni indlu, kodwa kungenziwa kuphela emva kokuphothulwa isivivinyo ukuvuza.

Kwesincane iphayiphi

Iphayiphi kuyinto sakhiwo esasibizwa yaqaphela uhlelo lwezokuthutha igesi. Kuye isicelo ke kungenziwa enikeziwe at izingcindezi ezihlukahlukene. Ngokwesibonelo, endabeni amapayipi main, lapho ingcindezi kuqhathaniswa eziphakemeyo, kepha izinhlelo ukusatshalaliswa, kungaba ukushintshwa.

I u ka iphayiphi ngaphandle kokuma umsebenzi kungenziwa kwenziwe ukulungisa kanye uxhumano abathengi ngabanye. Uhlelo ngeke isebenze ngaphandle kokuphazamiseka, futhi ukucindezela ngeke ziyancipha. Le nqubo ibizwa ozimele abandayo ngaphezulu ngokuthi futhi ngezinye izikhathi indawo indlela ezivamile, okubandakanya Welding amapayipi kanye kubhekwa zabasebenzi okhandlayo.

Kwesincane ku iphayiphi uma usebenzisa amapayipi epulasitiki esebenzisa nokufakwa noma izingxenye okwenyanga. Ngenxa yale njongo izakhi zensimbi, futhi indlela kuhlanganisa ukuxhumana lwavutha is ethe njo izakhiwo ezikhethekile emva kokufakwa. Waphatha ngensimbi Faka izingoma ekwazi ukuvikela ubuso kusukela nokugqwala ngenxa amanzi ingress ingadala ukugqwala izinqubo.

Cutting wenziwa ngokudala ifaka ka Alloys perpendicular ipayipi. I faka has a obuphelele ezisukela 70 kuya ku-100 mm kanti abaqhubeke uxhumano isokhethi pin. Le ndlela isikisela ukuthi osuke usushisa kakade ngensimbi Faka ayaduduleka amashubhu plastic. Indlela esetshenziswa ukudala egoba ka iphayiphi nge ingcindezi kancane. Uma ingcindezi isilinganiso ke ngaphambi ukugcwala kwamanzi kufanele zisetshenziswe polyethylene indawo powder uxhumano esizayo evumela elihlangana Friend izinto ezimbili.

Izici ubophele

Kwesincane engena amakhaza amanzi supply komsele kungenziwa kugcinwe ubuchwepheshe eziningana. Lokhu kungasebenza izinhlobo ezahlukene welds, okuyilezi:

• T-bar;
• Butt;
• ekhoneni;
• ezedlulayo.

Ukuthepha ngaphandle depressurization kusetshenzisiwe hhayi Saddles kuphela, kodwa futhi amadivayisi ezaziwa ngokuthi PGVM. Ngaphezu kwalokho, kungenzeka ukusebenzisa valve futhi izibopho. Uma okukhethiwe nge isiqhebezo, lo coupling is eziphothene kuya ipayipi negenkle igatsha valve unamathele ngekhamera. Umgodi kumele abe umsiki inkomishi whereupon isinqamu cut isuswe ngokusebenzisa ekamelweni, ukweqa valve. Lapho ukusebenza ngo Ibhokisi ekhona iphayiphi ngokuvumelana lobu buchwepheshe, ke flange ngemva kokususwa imisebenzi ngenhla ixhunyiwe.

Ngokuphathelene PGVM, kuba idivayisi okuyinto senzelwe evunyelwe ngaphandle depressurization. elementi ezisebenzayo igesi izinhlelo ezithinta ububanzi ku ezahlukene 186 kuya ku-529 mm. Nale divayisi ongenza luhlaka, ukudala pre-wokuvula, ububanzi okuzokwenza ukuthi zisukela kweziyizigidi ezingu-80 ukuze 140 mm.

isiphetho

Uma usebenzisa i-mortise collar ukuze amapayipi, emgqeni eyinhloko indlu yokuhlala kungaqinisekisa alondoloze nemithombo yamanzi legatsha. Ngezinye izikhathi kudingeka ukuxhuma umthengi eyengeziwe noma idivaysi ukuchelela. Uma uhlelo isebenzisa amanzi emthonjeni, le kwesincane kungase zimiswe kunoma iyiphi indawo. Uma sikhuluma central amanzi, imisebenzi enjalo eyenziwa tibali amanzi ukusetshenziswa. Ngakho kwesincane e komsele ingcindezi kungaba sihluke ubuchwepheshe okuyinto echazwe ngenhla.

Lokhu kungenxa yokuthi ingcindezi inethiwekhi yangaphakathi kuvaliwe nganoma yisiphi isikhathi. Ukwenza kanjalo kuphela ukumboza valve isikhungo. Ngakho-ke, ukuze enze lo msebenzi udinga ukulungiselela tee. Izikhundla kuzobandakanya isidingo sokukhipha amanzi, lokhu kwenziwa ngokuvula valve aphansi.
