I-valve yesango ye-flange yi-valve yesango kunye noqhagamshelwano lwe-flange, le ndlela yokudibanisa iyona nto ixhaphake kakhulu. Iivalvu zesango le-flange zizinzile kwaye zithembekile xa zisetyenziswa kwimibhobho, ngoko ke iivalve zesango le-flange zihlala zisetyenziswa kwimibhobho yoxinzelelo oluphezulu.

Xa ivalve yesango le-flange ivaliwe, umphezulu wokutywina unokuxhomekeka kuphela kuxinzelelo oluphakathi ukutywinwa, oko kukuthi, ukuxhomekeka kuxinzelelo oluphakathi ukucinezela indawo yokutywina yesango ukuya kwisihlalo sevalve kwelinye icala ukuqinisekisa ukutywinwa umphezulu wokutywina, onokuzitywina. Uninzi lweevalvu zesango zisebenzisa ukutywinwa okunyanzeliswayo, oko kukuthi, xa ivalve ivaliwe, isango kufuneka linyanzelwe ngokuchasene nesihlalo ngamandla angaphandle ukuqinisekisa ukutywinwa kwendawo yokutywina.

Isango levalve yesango lihamba ngokulandelelana kunye nesiqu sevalve, ebizwa ngokuba yivalve yesango lesikhondo sokuphakamisa (ekwabizwa ngokuba yivalve yesango elinyukayo). Ngokuqhelekileyo kukho intambo ye-trapezoidal kwintonga yokuphakamisa. Ngokusebenzisa i-nut engaphezulu kwevalve kunye ne-groove yesikhokelo kumzimba wevalve, intshukumo ejikelezayo iguqulwa ibe yintshukumo yomgca, oko kukuthi, i-torque yokusebenza ijikwa ibe yi-tyhust yokusebenza.

Xa i-valve ivuliwe, xa ukuphakama kokuphakama kwesango kufana ne-1: 1 amaxesha ububanzi be-valve, i-fluid passage ayivaliwe ngokupheleleyo, kodwa esi sikhundla asikwazi ukubeka iliso ngexesha lokusebenza. Ekusetyenzisweni kwangempela, i-apex ye-valve stem isetyenziswe njengophawu, oko kukuthi, indawo apho ayikwazi ukuvulwa, njengendawo yayo evulekile ngokupheleleyo. Ukuze kuthathelwe ingqalelo isenzeko sokutshixa ngenxa yokutshintsha kweqondo lobushushu, ivalve idla ngokuvulelwa kwi-apex position kwaye emva koko ibuyiselwe umva nge-1/2 ukuya ku-1 ukujika njengendawo evuleke ngokupheleleyo. Ngoko ke, indawo evuleke ngokupheleleyo yevalve imiselwa yindawo yesango (okt stroke>.

Kwezinye iivalve zesango, i-stem nut ibekwe kwisango, kwaye ukujikeleza kwe-handwheel kuqhuba ukujikeleza kwe-valve stem ukuphakamisa isango. Olu hlobo lwevalve lubizwa ngokuba yivalve yesango yesiqu esijikelezayo okanye ivelufa yesango elimnyama.

Ukufakwa kwevalve yesango leflange:

1. Qwalasela ingaphakathi lomngxuma wevalve kunye nendawo yokutywina phambi kofakelo, kwaye akukho bumdaka okanye amasuntswana esanti avumelekileyo ukuba abambelele;

2. Iibholithi zecandelo ngalinye loqhagamshelwano ziya kuqiniswa ngokulinganayo;

3. Khangela iindawo zokupakisha ukuba zixinzelelwe ngokuqinileyo, kungekhona nje ukuqinisekisa ukunyanzeliswa kokupakisha, kodwa nokuqinisekisa ukuvulwa okuguquguqukayo kwesango;

4. Ngaphambi kokufaka i-valve, umsebenzisi kufuneka ahlole imodeli yevalve, ubungakanani bokudibanisa kwaye anikele ingqalelo kwindlela ehamba ngayo ye-medium ukuqinisekisa ukuhambelana neemfuno zevalve;

5. Xa ufaka i-valve, umsebenzisi kufuneka agcine indawo efunekayo kwi-valve drive;

6. I-wiring yesixhobo sokuqhuba kufuneka iqhutywe ngokuhambelana nomzobo wocingo;

7. Ivalve yesango kufuneka igcinwe rhoqo, kwaye akukho kungqubana okanye ukucinezela kuvunyelwe ukuphepha ukuchaphazela isitywina.

Izixhobo ze-Newsway Valves

Umzimba wevalve ye-NSW kunye nemathiriyeli ye-trim inokubonelelwa ngohlobo lwe-Forged kunye nohlobo lokuCasa. Ecaleni kwezinto ezingenasici kunye ne-carbon steel, senza kwakhona iivalve kwizinto ezikhethekileyo ezifana ne-titanium, i-nickel alloys, i-HASTELLOY®*, i-INCOLOY®, i-MONEL®, i-Alloy 20, i-super-duplex, i-corrosion resistant alloys kunye ne-urea grade grade.
