I-Stainless Steel Gate Valve

Ingxenye yokuvula nokuvala ye-valve yesango yensimbi engenasici yisango, futhi isiqondiso sokunyakaza kwesango sibhekene nesiqondiso soketshezi. Isango lensimbi engagqwali linezindawo ezimbili zokuvala. Izindawo ezimbili zokuvala zevalvu yesango eyimodeli evame ukusetshenziswa kakhulu zakha umcengezi, futhi i-engeli ye-wedge iyahlukahluka ngamapharamitha wevalvu. Isango le-valve yesango le-wedge lingenziwa libe liphelele, elibizwa ngokuthi isango eliqinile; kungenziwa futhi isango elingakhiqiza ukuguqulwa okuncane ukuze kuthuthukiswe ukwenziwa kwayo futhi kunxephezele ukuphambuka kwe-angle yokuvala uphawu ngesikhathi sokucubungula. Ipuleti libizwa ngokuthi isango elinwebekayo. Insimbi engagqwali isango valve izinto zihlukaniswe CF8, CF8M, CF3, CF3M, 904L, Duplex Stainless Steel (4A, 5A, 6A).
Izinhlobo zama-valve esango lensimbi engagqwali zingahlukaniswa zibe ama-valve esango le-wedge kanye nama-valve esango ahambisanayo ngokusho kokucushwa kwendawo yokubeka uphawu. Ama-valve wesango le-Wedge angahlukaniswa abe: uhlobo lwesango elilodwa, uhlobo lwesango eliphindwe kabili kanye nohlobo lwesango lokunwebeka; i-parallel isango uhlobo lwe-valve yesango Ingahlukaniswa ngohlobo olulodwa lwesango kanye nohlobo lwesango eliphindwe kabili. Ihlukaniswe ngokuma kwentambo yesiqu se-valve, ingahlukaniswa ngezinhlobo ezimbili: i-valve yesango ye-stem evulekile kanye ne-valve yesango elimnyama. Lolu hlobo lwe-valve ngokuvamile kufanele lufakwe ngokuvundlile epayipini.
Lapho i-valve ivuliwe, lapho ukuphakama kokuphakama kwesango lilingana no-1: 1 izikhathi zobubanzi be-valve, i-fluid passage ivuliwe ngokuphelele, kodwa lesi sikhundla asikwazi ukuqapha ngesikhathi sokusebenza. Ekusetshenzisweni kwangempela, i-apex ye-valve stem isetshenziswa njengophawu, okungukuthi, indawo lapho ingakwazi ukuvulwa khona, njengesikhundla sayo esivulekile ngokugcwele. Ukuze ucabangele ukwenzeka kokukhiya ngenxa yokushintsha kwezinga lokushisa, i-valve ivamise ukuvulelwa endaweni ephezulu bese ihlehliswa ngo-1/2 kuya ku-1 ukujika njengendawo evuleke ngokugcwele. Ngakho-ke, indawo evulekile ngokugcwele ye-valve inqunywa indawo yesango (okungukuthi unhlangothi).
Kwamanye ama-valve esango, i-stem nut ibekwe esangweni, futhi ukujikeleza kwesondo lesandla kushayela ukujikeleza kwesiqu se-valve ukuphakamisa isango. Lolu hlobo lwe-valve lubizwa ngokuthi i-valve yesango lesiqu esijikelezayo noma i-valve yesango elimnyama.
