Xa ukuwelda umbhobho, umlomo ongalunganga emva kombhobho awukho kumgca osembindini, akukho msantsa kwisibini, umbhobho ongqindilili wodonga awuwuhlakuli umjelo, kwaye ububanzi kunye nokuphakama kwe-weld akuhambelani neemfuno zekhowudi yokwakha. .
Iziphumo: umbhobho ongalunganga awukho kumgca ophakathi uchaphazela ngokuthe ngqo umgangatho we-welding kunye nomgangatho wokuqonda. Akukho msantsa kwesi sibini, umbhobho ongqindilili wodonga awuwuhlambi umjelo, ububanzi kunye nokuphakama kwe-weld akuhambelani neemfuno ze-welding ayikwazi ukuhlangabezana neemfuno zamandla.
Imilinganiselo: emva kwe-welding umbhobho, umbhobho akufanele uphazamiseke kumgca ophakathi; umsantsa kufuneka ushiywe; umbhobho ongqindilili wodonga kufuneka uhlatywe. Ukongeza, ububanzi kunye nobude be-weld buya kudityaniswa ngokweemfuno ezichaziweyo.

Umbhobho ungcwatywe ngokuthe ngqo kumhlaba onomkhenkce kunye nomhlaba ongacocwanga, kwaye izithuba kunye nendawo yokuxhasa imibhobho ayifanelekanga, kwaye nakwimo yesitena esomileyo seyadi.
Iziphumo: Ngenxa yenkxaso engazinzanga, umbhobho wonakaliswe kwinkqubo yokuxinwa kwe-backfill, okubangelwa ukulungiswa kwakhona kunye nokulungiswa.
Imilinganiselo: umbhobho awusayi kungcwatywa kumhlaba onomkhenkce kunye nomhlaba ongacocwanga, isithuba sepier kufuneka sihlangabezane neemfuno zemigaqo yolwakhiwo, i-pad yenkxaso kufuneka yomelele, ngakumbi ujongano lwemibhobho, akufuneki luthwale amandla okucheba. Izitena zokuxhasa izitena kufuneka zakhiwe ngamanzi kunye nodaka lwesanti ukuqinisekisa ukuthembeka kunye nokuqina.

Ibholithi yokwandiswa kwezinto zokuxhasa umbhobho osisigxina iphantsi, i-aperture ye-bolt yokwandisa ukufakela inkulu kakhulu okanye i-bolt yokwandisa ifakwe eludongeni lwezitena okanye nakwindonga yokukhanya.
Iziphumo: inkxaso yombhobho ikhululekile, i-deformation yombhobho, okanye iyawa.
Imilinganiselo: iibholiti zokwandisa kufuneka zikhethe iimveliso ezifanelekileyo, ukuba kuyimfuneko, kufuneka zithathwe isampuli zokuhlolwa kovavanyo, i-aperture yokufaka i-bolts yokwandisa akufanele ibe ngaphezu kwe-2mm ububanzi bangaphandle beebholiti zokwandisa, iibholiti zokwandisa kufuneka zisetyenziswe kwisakhiwo sekhonkrithi.

I-flange plate kunye ne-liner ayinamandla ngokwaneleyo, kwaye iibholiti zokudibanisa zifutshane okanye zincinci ububanzi. I-Rubber pad isetyenziselwa umbhobho we-thermal, i-cushion ephindwe kabini okanye i-pad ethambekele kumbhobho wamanzi abandayo, kunye ne-flange liner ephumela kwi-tube.
Iziphumo: udibaniso lwepleyiti yeflange aluqinanga, okanye nomonakalo, ukuvuza. I-flange ifake kwi-tube iya kwandisa ukuchasana nokuhamba.
Imilinganiselo: Ipleyiti yeflange yombhobho kunye ne-liner kufuneka ihlangabezane neemfuno zoyilo lombhobho woxinzelelo lokusebenza.
I-rubber asbestos pad yokufudumeza kunye nemibhobho yokuhambisa amanzi ashushu kunye neepads zerabha zokubonelela ngamanzi kunye nemibhobho yokuhambisa amanzi.
I-flange liner ayiyi kungena kwi-tube, isangqa sayo sangaphandle kwi-flange bolt hole ifanelekile. Akukho pad ethotyiweyo okanye iilinen ezininzi ziya kubekwa embindini weflange. Ububanzi bebholiti edibanisa i-flange kufuneka ibe ngaphantsi kwe-2mm enkulu kune-aperture yepleyiti ye-flange, kwaye ubude bentonga ye-bolt ephumayo kufuneka ibe yi-1 / 2 yobunzima be-nut.

Iinkcukacha kunye neemodeli zevalve efakiweyo ayihambelani neemfuno zoyilo.
Ngokomzekelo, uxinzelelo lwe-valve lungaphantsi koxinzelelo lovavanyo lwenkqubo; ivalve yesango kumbhobho wesebe lamanzi okutya xa ububanzi bombhobho bungaphantsi okanye bulingana no-50mm; ezomileyo kunye nezikhuphukeli zokufudumeza amanzi ashushu; kunye nombhobho wokufunxa wempompo yomlilo wamkela ivalve yebhabhathane.
Iziphumo: kuchaphazela ukuvulwa okuqhelekileyo kunye nokuvalwa kwe-valve kunye nokulungelelanisa ukuchasana, uxinzelelo kunye neminye imisebenzi. Nokuba kubangele ukusebenza kwenkqubo, umonakalo wevalve unyanzelekile ukuba ulungise.
Imilinganiselo: Ziqhelanise nomda wokusetyenziswa kweevalvu ezahlukeneyo, kwaye ukhethe ukucaciswa kunye neemodeli zeevalvu ngokweemfuno zoyilo. Uxinzelelo oluncinci lwevalvu luya kuhlangabezana neemfuno zoxinzelelo lovavanyo lwenkqubo. Ngokutsho kwekhowudi yokwakha: i-valve yokumisa iya kusetyenziswa xa ububanzi bombhobho bungaphantsi okanye bulingana no-50mm; Ivalve yesango iya kusetyenziswa xa i-diameter yombhobho ingaphezulu kwe-50mm. Ukufudumeza kwamanzi ashushu omile, ivelufa yokulawula ethe nkqo kufuneka isetyenziswe ivelufa yesango, umbhobho wokufunxa impompo yamanzi omlilo akufanelekanga ukusetyenziswaivelufa butterfly.
Ngaphandle koko, i-Tianjin Tanggu Water Seal Valve Co., Ltd yivalve yesitulo esinelastiki ephucukileyo exhasa amashishini, iimveliso zisitulo esilastiki sebhabhathane, ivalve yebhabhathane, ilug butterfly valve,Ivalve yebhabhathane eneflange kabini, ivalve yebhabhathane eneflange ephindwe kabini, ivalve yokulinganisa,Ivalve yokujonga ipleyiti ephindwe kabini, Y-Strainer njalo njalo. E-Tianjin Tanggu Water Seal Valve Co., Ltd., siyazingca ngokubonelela ngeemveliso zodidi lokuqala ezihlangabezana neyona migangatho iphezulu yoshishino. Ngoluhlu lwethu olubanzi lweevalvu kunye nokufakelwa, unokusithemba ukubonelela ngesisombululo esifanelekileyo kwinkqubo yakho yamanzi. Qhagamshelana nathi namhlanje ukuze ufunde ngakumbi malunga neemveliso zethu kunye nendlela esinokukunceda ngayo.
