Ii-valve yesangokuyisango elivulekayo nelivalayo.Indlela yokuhamba yesango i-perpendicular to the direction of the fluid.I-valve yesango ingavulwa ngokugcwele futhi ivalwe ngokugcwele, futhi ayikwazi ukulungiswa noma ukucindezelwa.I-valve yesango ivalwe ngokuthintana phakathi kwesihlalo se-valve nepuleti lesango.Ngokuvamile, indawo yokuvala izobe ibekwe phezu kwezinto zensimbi ukuze kwandiswe ukumelana nokugqokwa, njengokuvela ku-1Cr13, STL6, insimbi engagqwali, njll. Isango linesango eliqinile nesango elinwebekayo.Ngokusho kwamasango ahlukene, i-valve yesango ihlukaniswe i-valve yesango eliqinile kanye ne-valve yesango elinwebekayo.

Ingxenye yokuvula nokuvala ye-valve yesango yisango, futhi isiqondiso sokunyakaza kwesango sibhekene nesiqondiso soketshezi.Ii-valve yesangoingavulwa ngokugcwele futhi ivalwe ngokugcwele, futhi ayikwazi ukulungiswa noma ukuphonswa.Isango linezindawo ezimbili zokuvala.Izindawo ezimbili zokuvala zevalvu yesango yemodi evame ukusetshenziswa kakhulu zakha umumo we-wedge.I-engeli ye-wedge iyahlukahluka nemingcele yevalvu, ngokuvamile engu-5°, no-2°52' lapho izinga lokushisa elimaphakathi lingekho phezulu.Isango le-valve yesango le-wedge lingenziwa libe liphelele, elibizwa ngokuthi isango eliqinile;ingenziwa futhi isango elingakhiqiza inani elincane lokuguqulwa ukuze lithuthukise ubuciko bayo futhi lenze ukuphambuka kwe-angle yokuvala uphawu ngesikhathi sokucubungula.Ipuleti libizwa ngokuthi isango elinwebekayo.Lapho i-valve yesango ivaliwe, indawo yokuvala ingavalwa kuphela ngokucindezela okuphakathi, okungukuthi, ukuthembela ekucindezelweni okuphakathi ukuze ucindezele indawo yokuvala yesango esihlalweni se-valve ngakolunye uhlangothi ukuze kuqinisekiswe ukuvala uphawu. ubuso, obuzivala.Ama-valve amaningi esango avaliwe ngenkani, okungukuthi, lapho i-valve ivaliwe, isango kufanele liphoqwe ngokumelene nesihlalo se-valve ngamandla angaphandle ukuze kuqinisekiswe ukuqina kwendawo yokuvala.Isango levalvu yesango lihamba ngokulandelana nesiqu se-valve, ebizwa ngokuthi i-lift-rod gate valve, eyaziwa nangokuthi i-valve yesango lenduku ekhuphukayo.Ngokuvamile, kunemicu ye-trapezoidal ku-lift rod.Ngenati elingaphezulu kwevalvu kanye negroove eqondisayo emzimbeni wevalvu, ukunyakaza okujikelezayo kuguqulwa kube ukunyakaza okulandelanayo, okungukuthi, i-torque yokusebenza iguqulwa ibe i-thrust yokusebenza.Lapho i-valve ivuliwe, lapho ukuphakama kokuphakama kwesango lilingana no-1: 1 izikhathi ububanzi be-valve, isiteshi samanzi singenasici, kodwa lesi sikhundla asikwazi ukuqapha ngesikhathi sokusebenza.Ekusetshenzisweni kwangempela, i-apex ye-valve stem isetshenziswa njengesibonakaliso, okungukuthi, isikhundla lapho singakwazi ukuvulwa khona, njengendawo yayo evulekile ngokugcwele.Ukuze ucabangele isenzakalo sokukhiya esibangelwa ukushintsha kwezinga lokushisa, ngokuvamile sivulwa endaweni ephezulu, bese sibuyela ku-1 / 2-1 ukuphenduka, njengesikhundla se-valve evulekile ngokugcwele.Ngakho-ke, isikhundla esivulekile ngokugcwele se-valve sinqunywa ngokusho kwendawo yesango, okungukuthi, ukushaywa.Kwabanyeama-valve esango, i-stem nut ibekwe esangweni, futhi ukujikeleza kwesondo lesandla kuqhuba isiqu se-valve ukuze sijikeleze, okwenza isango liphakame.Lolu hlobo lwe-valve lubizwa ngokuthi i-valve yesango lesiqu esijikelezayo, noma i-valve yesango elimnyama.
