I-Stainless Steel Check Valve Seat iyingxenye yokuvalwa okunembayo ehlinzeka indawo ebalulekile yokukhwelana yediski ye-valve yokuhlola noma ibhola, iqinisekisa ukuvala kahle nokuvimbela ukugeleza emuva kumasistimu amapayipi. Isihlalo se-valve kumele simelane nokuguguleka, ukugqwala, ukulimala kwe-cavitation, kanye ne-galling ngenkathi sigcina ukuzinza kwe-dimensional ngaphansi kwengcindezi nokuguquguquka kwezinga lokushisa. Ukuqedwa okungaphezulu kusixhumi esibonakalayo sokuvala kuthinta ngqo ukuvuza nempilo yomjikelezo wamavalvu.
I-Ningbo Ruican ikhiqiza izihlalo zamavalvu okuhlola insimbi engagqwali isebenzisa inqubo yokutshala imali ye-silica sol, ikhiqiza izihlalo ezinekhwalithi ephezulu kakhulu, ukujiya kodonga okungaguquki, kanye namaphrofayili angaphakathi ayinkimbinkimbi. Indlela yokufaka utshalomali ifaneleka ikakhulukazi ama-alloys amelana nokugqwala njenge-CF8M (316 stainless), CF3M (316L stainless), kanye namamaki angenasici ayi-duplex, okunzima ukuwafaka umshini osuka esitokisini sebha eqinile futhi othambekele ekusebenzeni lukhuni.
Ngemuva kokuphonswa, isihlalo ngasinye se-valve sisebenza ngokunemba ngomshini we-CNC futhi sifakwe izintambo ukuze kuzuzwe ukugqama okudingekayo kwendawo yokubeka uphawu kanye nokuqina kwendawo. Amandla ethu okugoqa angaphakathi afinyelela ukuvala indawo ephansi ibe ngaphakathi kwamabhendi okukhanya angu-2 (0.0005 mm), iqinisekisa ukuvala okuqinile kwebhamuza nge-API 598 kanye namazinga okuhlola we-MSS-SP-61. Sisebenzela abakhiqizi be-valve, osonkontileka be-EPC bamapayipi, nabahlinzeki besistimu yoketshezi lwezimboni emhlabeni jikelele.
