Yini okufanele yenziwe ngesikhathi sokufakwa kwevalvu – ingcenye yesibili

Namhlanjesi siragela phambili nokukhuluma ngeenqabo zokufaka amavalvu:

Lokha nakuwelda amapayipi, umlomo ongakalungi ngemva kwephayiphu awukho emgqeni ophakathi, akukho sikhala phakathi kwepayipi, iphayiphu ebodeni elidephileko ayifaki umgodi, begodu ububanzi nokuphakama kwe-weld akuhlangabezani neemfuneko zekhodi yokwakha.
Imiphumela: iphayiphu engakalungi yokuphuma ayikho emgqeni ophakathi kuthinta ngqo ikhwalithi yokuwelda nekhwalithi yokubona. Akukho igebe phakathi kwepayipi, ipayipi ebodeni elidephileko alifaki umsele, ububanzi nokuphakama kwe-weld akuhlangabezani neemfuneko zokuwelda akukwazi ukuhlangabezana neemfuneko zamandla.
Iindlela: ngemva kokuwelda ipayipi, ipayipi akukafaneli bona iphaphatheke emgqeni ophakathi; isikhala kufanele sitjhiywe; ipayipi ebodeni elidephileko kufanele likhutjhwe. Ukungezelela, ububanzi nokuphakama kwe-weld kuzokuhlanganiswa ngokuya ngeemfuneko zokucaciswa.

Iphayiphi ingcwatjhwe ngqo ehlabathini eliqandileko kanye nehlabathi engakahlanzwa, begodu ukuhlukaniswa nobujamo bamapayipi wokusekela akukalungi, begodu ngitjho nangendlela yesitina esomileko sejarada.
Imiphumela: Ngebanga lokusekelwa okungazinzileko, iphayiphi yalimala ngesikhathi sokugcwalisa emuva, okurholele ekusetjenzisweni kabutjha nokulungiswa.
Iinlinganiso: iphayiphi akukafaneli ingcwatjhwe ehlabathini eliqandileko nehlabathini engakahlanzwa, isikhala se-pier kufanele sihlangabezane neemfuneko zokwakha, iphedi yokusekela kufanele ibe namandla, khulukhulu isikhombisi sepayipi, akukafaneli sithwale amandla wokusika. Iinqhema ezisekela isitina kufanele zakhiwe ngamanzi nesihlabathi ukuqinisekisa ukuthembeka nokuqina.

Ibholthi yokunweba yezinto ezisekela amapayipi angaguqukiko iphansi, ukuvuleka kwebholthi yokunweba yokufaka kukhulu khulu nofana ibholthi yokunweba ifakwe ebodeni lesitina nofana ebodeni lokukhanya.
Imiphumela: isekelo lephayiphu likhululekile, iphayiphu iyaguquka, nofana iyawa.
Iindlela: amabhawudo wokunweba kufanele akhethe imikhiqizo efanelekako, nangabe kuyatlhogeka, kufanele athathwe isampula ukuhlolwa kokuhlolwa, ukuvuleka kokufaka amabhawudo wokunweba akukafaneli kube khulu kune-2mm ububanzi bangaphandle bamabhawudo wokunweba, amabhawudo wokunweba kufanele asetjenziswe esakhiweni sekhonkrithi.

Ipuleti ye-flange ne-liner azinamandla ngokwaneleko, begodu amabhawudo wokuhlanganisa amafitjhani nofana mncani ngobubanzi. Iphedi yerabha isetjenziselwa iphayiphu yokutjhisa, umcamelo ophindwe kabili nofana iphedi etjhingako yephayiphi yamanzi abandako, kanye ne-flange liner ephuma ngaphakathi kwetjhubhu.
Imiphumela: ukuxhumana kwepuleti ye-flange akukaqini, nofana kulimale, ukuvuza. Ukufakwa kwe-flange ngaphakathi kwetjhubhu kuzokwandisa ukujamelana nokugeleza.
Iinlinganiso: Ipuleti ye-flange yephayiphu kanye ne-liner kufanele ihlangabezane neemfuneko zokusebenza komtjhini wephayiphu.
Iphedi ye-asbestos yerabha yokufuthumeza namaphayiphi wokuphakela amanzi atjhisako kanye namaphedi werabha wokuphakela amanzi namaphayiphi wokukhipha amanzi.
I-flange liner akukafaneli ingene ngaphakathi kwetjhubhu, isiyingi sayo sangaphandle ukuya emgodini we-flange bolt sifanele. Akukho phedi etjhingako namkha amalayini amanengi azokufakwa phakathi kwefletjhi. Ububanzi bebholthi ehlanganisa iflanji kufanele bube ngaphasi kwe-2mm ubukhulu ukudlula ukuvuleka kwepuleti leflentjhi, begodu ubude be-nut ye-bolt rod ephumako kufanele bube yi-1 / 2 yobukhulu be-nut.

Iinqophiso namamodeli wevalvu efakiweko awahlangabezani neemfuneko zokuklama.
Ukwenza isibonelo, umfutho wevalvu ungaphasi komfutho wokuhlolwa kwesistimu; ivalvu yesango lephayiphu yamagatja wamanzi wokuphakela lokha ububanzi bephayiphu bungaphasi nofana bulingana nama-50mm; i-dry kanye ne-risers yokufuthumeza amanzi atjhisako; begodu iphayiphu yokudonsa yepompo yomlilo yamukela ivalvu ye-butterfly.
Imiphumela: ithinta ukuvulwa nokuvalwa okujayelekileko kwevalvu begodu ilungise ukujamelana, ukugandeleleka neminye imisebenzi. Ngitjho nanyana kubangele ukusebenza kwesistimu, ukulimala kwevalvu kukateleleka bona kulungiswe.
Iinlinganiso: Yazi ububanzi bokusetjenziswa kwamavalvu ahlukahlukeneko, begodu ukhethe ukucaciswa namamodeli wamavalvu ngokuya ngeemfuneko zokuklama. Umfutho wevalvu uzakuhlangabezana neemfuneko zomfutho wokuhlolwa kwesistimu. Ngokuya ngekhodi yokwakha: ivalvu yokumisa izakusetjenziswa lokha ububanzi bephayiphu bungaphasi nofana bulingana nama-50mm; ivalvu yesango izakusetjenziswa lokha ububanzi bephayiphu bungaphezu kwama-50mm. Ukufuthumala kwamanzi atjhisako omileko, ivalvu yokulawula eqondileko kufanele isetjenziswe ivalvu yesango, iphayiphu yokudosa ipompo yamanzi womlilo akukafaneli isetjenzisweivalvu yevivane.

Ngaphandle kwalokho, i-Tianjin Tanggu Water Seal Valve Co., Ltd. yi-elastic seat valve esekela amabhizinisi, imikhiqizo yi-elastic seat wafer butterfly valve, lug butterfly valve,i-velve ye-butterfly ye-flange ephindwe kabili, i-double flange eccentric butterfly valve, i-balance valve,i-wafer dual plate check valve, Y-Strainer njalonjalo. E-Tianjin Tanggu Water Seal Valve Co., Ltd., siyazikhakhazisa ngokunikela ngemikhiqizo esezingeni eliphezulu ehlangabezana namazinga aphezulu webubulo. Ngamavalvu wethu ahlukahlukeneko, ungasithemba bona sizokunikela ngesisombululo esihle khulu sehlelo lakho lamanzi. Sithinta namhlanjesi ukufunda kabanzi ngemikhiqizo yethu nokuthi singakusiza njani.
