Xa kudityaniswa imibhobho, umlomo ongalunganga emva kombhobho awukho kumgca osembindini, akukho sithuba kwisibini, umbhobho wodonga ongqindilili awuwufaki umngxuma, kwaye ububanzi nokuphakama kombhobho akuhlangabezani neemfuno zekhowudi yokwakha.
Iziphumo: umbhobho ophumayo ongalunganga awukho kumgca ophakathi uchaphazela ngqo umgangatho wokuwelda kunye nomgangatho wokuqonda. Akukho sithuba kwisibini, umbhobho wodonga otyebileyo awuwufaki umngxuma, ububanzi kunye nokuphakama kwe-weld akuhlangabezani neemfuno zokuwelda akunakuhlangabezana neemfuno zamandla.
Imilinganiselo: emva kokuwelda umbhobho, umbhobho akufuneki udityaniswe kumgca osembindini; isithuba kufuneka sishiywe; umbhobho wodonga otyebileyo kufuneka uxotyulwe ngefosholo. Ukongeza, ububanzi kunye nokuphakama kombhobho kufuneka kudityaniswe ngokweemfuno zeenkcukacha.

Umbhobho ungcwatywe ngqo kumhlaba oqandisiweyo kunye nomhlaba okhululekileyo onganyangwanga, kwaye isithuba kunye nendawo yeentsika zokuxhasa umbhobho azifanelekanga, kwaye zikwakwimo yezitena ezomileyo zeyadi.
Iziphumo: Ngenxa yenkxaso engaguqukiyo, umbhobho wonakele ngexesha lokuxinana kwe-backfill, nto leyo eyabangela ukulungiswa ngokutsha.
Amanyathelo: umbhobho awuzukugqunywa kumhlaba oqandisiweyo kwaye umhlaba okhululekileyo unganyangwanga, isithuba seepier kufuneka sihlangabezane neemfuno zeenkcukacha zokwakha, i-support pad kufuneka ibe namandla, ingakumbi indawo yokudibanisa umbhobho, ayifanele ithwale amandla okucheba. Ii-sitear support piers kufuneka zakhiwe ngamanzi kunye nesanti ukuze kuqinisekiswe ukuthembeka nokuqina.

Ibholthi yokwandisa yezinto ezixhasa umbhobho osisigxina iphantsi, umngxuma webholthi yokwandisa yokufaka mkhulu kakhulu okanye ibholthi yokwandisa ifakwe eludongeni lwezitena okanye eludongeni olukhanyayo.
Iziphumo: inkxaso yombhobho ikhululekile, ukuguquka kombhobho, okanye ukuwa.
Amanyathelo: iibholiti zokwandisa kufuneka zikhethe iimveliso ezifanelekileyo, ukuba kuyimfuneko, kufuneka zisampulwe ukuze zihlolwe uvavanyo, umngxuma wokufaka iibholiti zokwandisa akufuneki ube ngaphezu kwe-2mm ububanzi bangaphandle beebholiti zokwandisa, iibholiti zokwandisa kufuneka zifakwe kwisakhiwo sekhonkrithi.

Ipleyiti yeflange kunye ne-liner azinamandla ngokwaneleyo, kwaye iibholithi ezidibanisayo zimfutshane okanye zincinci ububanzi. I-rubber pad isetyenziselwa umbhobho wobushushu, i-cushion ephindwe kabini okanye i-integrated pad yombhobho wamanzi abandayo, kunye ne-flange liner ephumayo kwityhubhu.
Iziphumo: uqhagamshelo lwepleyiti yeflange aluqinanga, okanye alunamonakalo, luyinto evuzayo. Ukufakwa kweflange kwityhubhu kuya kwandisa ukumelana nokuhamba kwamanzi.
Imilinganiselo: Ipleyiti yeflange yombhobho kunye ne-liner kufuneka zihlangabezane neemfuno zoxinzelelo lokusebenza koyilo lombhobho.
Iphedi yerabha ye-asbestos yokufudumeza kunye nemibhobho yokuhambisa amanzi ashushu kunye neephedi zerabha zemibhobho yokuhambisa amanzi kunye neyokukhupha amanzi.
I-flange liner ayifanele ingene kwityhubhu, isangqa sayo sangaphandle ukuya kumngxuma we-flange bolt sifanelekile. Akukho pad etyebileyo okanye ii-liners ezininzi eziza kubekwa embindini we-flange. Ububanzi be-bolt edibanisa i-flange kufuneka bube ngaphantsi kwe-2mm bukhulu kunomngxuma wepleyiti ye-flange, kwaye ubude be-nut ephumayo yentonga ye-bolt kufuneka bube yi-1/2 yobukhulu be-nut.

Iinkcukacha kunye neemodeli zevalvu efakiweyo azihlangabezani neemfuno zoyilo.
Umzekelo, uxinzelelo oluqhelekileyo lwevalvu lungaphantsi koxinzelelo lovavanyo lwenkqubo; ivalvu yesango yombhobho wamanzi okutya xa ububanzi bombhobho bungaphantsi okanye bulingana ne-50mm; i-dry kunye ne-risers zokufudumeza amanzi ashushu; kwaye umbhobho wokufunxa umbhobho womlilo usebenzisa ivalvu yebhabhathane.
Iziphumo: zichaphazela ukuvulwa nokuvalwa okuqhelekileyo kwevalvu kwaye zilungelelanise ukumelana, uxinzelelo kunye neminye imisebenzi. Nokuba ibangele ukusebenza kwenkqubo, umonakalo wevalvu uyanyanzeleka ukuba ulungiswe.
Amanyathelo: Yazi ububanzi bokusetyenziswa kweevalvu ezahlukeneyo, kwaye ukhethe iinkcukacha kunye neemodeli zeevalvu ngokweemfuno zoyilo. Uxinzelelo oluqhelekileyo lwevalvu kufuneka luhlangabezane neemfuno zoxinzelelo lovavanyo lwenkqubo. Ngokwekhowudi yokwakha: ivalvu yokumisa mayisetyenziswe xa ububanzi bombhobho bungaphantsi okanye bulingana ne-50mm; ivalvu yesango mayisetyenziswe xa ububanzi bombhobho bungaphezulu kwe-50mm. Ivalvu yokulawula eshushu yomile, ethe nkqo mayisetyenziswe ivalvu yesango, iphayiphi yokufunxa amanzi omlilo akufuneki isetyenziswe.ivalvu yebhabhathane.
Ngaphandle koko, iTianjin Tanggu Water Seal Valve Co., Ltd. yivalvu yesihlalo elastiki ephucukileyo exhasa amashishini, iimveliso zezi: ivalvu yebhabhathane yesihlalo esithambileyo, ivalvu yebhabhathane yelug,ivalvu yebhabhathane ejikelezayo ephindwe kabini, ivalvu yebhabhathane engaqhelekanga ephindwe kabini, ivalvu yokulinganisela,ivalvu yokujonga ipleyiti ezimbini ye-wafer, i-Y-Strainer njalo njalo. KwiTianjin Tanggu Water Seal Valve Co., Ltd., siyazingca ngokubonelela ngeemveliso ezikumgangatho ophezulu ezihlangabezana nemigangatho ephezulu yoshishino. Ngoluhlu lwethu olubanzi lweevalvu kunye nezixhobo, ungasithemba ukuba siza kubonelela ngesisombululo esifanelekileyo kwinkqubo yakho yamanzi. Qhagamshelana nathi namhlanje ukuze ufunde ngakumbi malunga neemveliso zethu kunye nendlela esinokukunceda ngayo.
