Namuhla siyaqhubeka nokukhuluma ngezinyathelo zokuphepha zokufakwa kwe-valve:
I-Taboo 7
Lapho ipayipi i-welding, umlomo ongalungile ngemva kwepayipi awukho emgqeni ophakathi nendawo, alikho igebe kubhangqa, ipayipi eliwugqinsi lodonga aliyifosholo i-groove, futhi ububanzi nokuphakama kwe-weld akuhlangabezani nezidingo zekhodi yokwakha. .
Imiphumela: ukuphuma okungalungile kwepayipi akukho emgqeni ophakathi kuthinta ngokuqondile ikhwalithi yokushisela kanye nekhwalithi yokubona. Alikho igebe ku-pair, ipayipi lodonga eliwugqinsi aliyifaki i-groove, ububanzi nokuphakama kwe-weld akuhlangabezani nezidingo ze-welding ayikwazi ukuhlangabezana nezidingo zamandla.
Izinyathelo: ngemva kokushisela ipayipi, ipayipi akufanele inyakaze emgqeni ophakathi; igebe kufanele lishiywe; ipayipi eliwugqinsi odongeni kufanele lifoswe. Ngaphezu kwalokho, ububanzi nobude be-weld buzoshiselwa ngokuya ngezidingo ezibekiwe.
I-Taboo 8
Ipayipi ligqitshwe ngokuqondile enhlabathini eqandisiwe kanye nomhlabathi ovulekile ongalungiswanga, futhi ukuhlukana kanye nendawo yezinsimbi zokusekela amapayipi akulungile, futhi ngisho nangesimo sesitini segceke esomile.
Imiphumela: Ngenxa yokwesekwa okungazinzile, ipayipi lonakaliswa ngesikhathi sokuminyana kokugcwalisa, okuholele ekusebenzeni kabusha nokulungiswa.
Izinyathelo: ipayipi akufanele lingcwatshwe enhlabathini eqandisiwe kanye nomhlabathi oxegayo ongalungiswanga, ukuhlukaniswa kwezinsimbi kufanele kuhlangabezane nezidingo zemininingwane yokwakha, indawo yokusekela kufanele ibe namandla, ikakhulukazi isixhumi esibonakalayo sepayipi, akufanele ithwale amandla okugunda. Izinsimbi zokusekela izitini kufanele zakhiwe ngamanzi kanye ne-sand slurry ukuqinisekisa ubuqotho nokuqina.
Isiqephu 9
Ibhawodi yokunweba yezinto ezisekela ipayipi engaguquki ingaphansi, indawo yokuvula ibhowodi yokunweba yokufakwa inkulu kakhulu noma ibholidi yokwandisa ifakwe odongeni lwezitini noma ngisho odongeni lokukhanya.
Imiphumela: ukusekelwa kwepayipi kukhululekile, ukuguquguquka kwepayipi, noma ukuwa.
Izinyathelo: amabhawodi okunweba kufanele akhethe imikhiqizo efanelekayo, uma kunesidingo, kufanele athathwe isampula ukuze ahlolwe, indawo yokuvula yokufaka amabhawodi okunweba akufanele ibe mkhulu kunobubanzi obungu-2mm obungaphandle bamabhawodi wokunweba, amabhawodi okunweba kufanele asetshenziswe esakhiweni sikakhonkolo.
Taboo 10
Ipuleti le-flange kanye ne-liner aziqinile ngokwanele, futhi ama-bolts okuxhuma mafushane noma amancane ngobubanzi. Iphedi yerabha isetshenziselwa ipayipi elishisayo, umcamelo ophindwe kabili noma iphedi ethambekele yepayipi lamanzi abandayo, kanye nomugqa we-flange ophumela eshubhu.
Imiphumela: ukuxhumeka kwepuleti le-flange akuqinile, noma ngisho nomonakalo, isenzakalo sokuvuza. I-flange efakwe ku-tube izokwandisa ukumelana nokugeleza.
Izinyathelo: Ipuleti le-pipe flange kanye ne-liner kumele ihlangabezane nezidingo zokucindezela kokusebenza kwe-design yamapayipi.
Iphedi ye-asbestos yerabha yokushisisa namapayipi okuhambisa amanzi ashisayo namapayipi enjoloba okuhambisa amanzi kanye namapayipi okukhipha amanzi.
I-flange liner akufanele ingene ku-tube, indilinga yayo yangaphandle ukuya emgodini we-flange bolt ifanelekile. Awekho iphedi ethambekele noma amalayini amaningana azobekwa phakathi kwe-flange. Ububanzi bebhawodi elixhuma i-flange kufanele bube buncane kuno-2mm ngaphezu kwendawo yokuvula ipuleti le-flange, futhi ubude bentonga yebhawodi ephumayo kufanele bube ngu-1/2 wogqinsi lwentongomane.
I-Taboo 11
Ukucaciswa namamodeli we-valve efakiwe akuhlangabezani nezidingo zokuklama.
Isibonelo, ingcindezi ebizwa ngokuthi i-valve ingaphansi kwengcindezi yokuhlola uhlelo; i-valve yesango yepayipi legatsha lamanzi okuphakelayo lapho ububanzi bepayipi bungaphansi noma bulingana no-50mm; okomile nezikhuphukeli zokufudumeza amanzi ashisayo; futhi ipayipi lokumunca iphampu yomlilo lithatha ivalve yevemvane.
Imiphumela: kuthinta ukuvulwa nokuvala okuvamile kwe-valve futhi ulungise ukumelana, ukucindezela neminye imisebenzi. Ngisho kubangele ukusebenza kwesistimu, umonakalo we-valve uphoqeleka ukuba ulungise.
Izinyathelo: Yazi ububanzi bokusetshenziswa kwamavalvu ahlukahlukene, bese ukhetha imininingwane namamodeli wamavalvu ngokuya ngezidingo zokuklama. Ukucindezela okulinganiselwe kwe-valve kuzohlangabezana nezidingo zokucindezela kokuhlolwa kwesistimu. Ngokusho kwekhodi yokwakha: i-valve yokumisa izosetshenziswa lapho ububanzi bepayipi bungaphansi noma bulingana no-50mm; I-valve yesango izosetshenziswa uma ububanzi bepayipi bukhulu kuno-50mm. Ukushisa kwamanzi ashisayo omile, i-valve yokulawula mpo kufanele isetshenziswe i-valve yesango, ipayipi lokudonsa amanzi omlilo akufanele lisetshenzisweuvemvane valve.
Ngaphandle kwalokho, i-Tianjin Tanggu Water Seal Valve Co., Ltd. iyi-valve yesihlalo esinwebekayo esezingeni eliphezulu esekela amabhizinisi, imikhiqizo i-elastic seat wafer butterfly valve, i-lug butterfly valve,i-valve ye-butterfly ene-flange ephindwe kabili, i-valve ye-butterfly ene-flange ephindwe kabili, i-valve yebhalansi,i-valve yokuhlola ipuleti elicwecwe kabili, Y-Strainer nokunye. E-Tianjin Tanggu Water Seal Valve Co., Ltd., siyaziqhenya ngokuhlinzeka ngemikhiqizo esezingeni eliphezulu ehlangabezana namazinga aphezulu embonini. Ngohlu lwethu olubanzi lwama-valve nokufakwa, ungasethemba ukuthi sizokunikeza isisombululo esiphelele sohlelo lwakho lwamanzi. Xhumana nathi namuhla ukuze ufunde kabanzi mayelana nemikhiqizo yethu nokuthi singakusiza kanjani.
