I I-Valve Yokulawula Izinga Lokushisaiyisango lokuvula nelokuvala. Indlela yokuhamba kwesango iqonde ngqo ohlangothini loketshezi. I-Valve Yokulawula Izinga Lokushisa ingavulwa ngokugcwele futhi ivalwe ngokuphelele, futhi ayikwazi ukulungiswa noma ukugoqwa. I-Valve Yokulawula Izinga Lokushisa ivalwe ngokuthintana phakathi kwesihlalo se-valve nepuleti lesango. Ngokuvamile, indawo yokuvala izobekwa ngezinto zensimbi ukwandisa ukumelana nokuguguleka, njengokufaka i-1Cr13, STL6, insimbi engagqwali, njll. Isango linesango eliqinile nesango elinwebekayo. Ngokusho kwamasango ahlukene, i-Valve Yokulawula Izinga Lokushisa ihlukaniswe ibe yi-Valve Yokulawula Izinga Lokushisa eqinile kanye ne-Valve Yokulawula Izinga Lokushisa enwebekayo.

Ingxenye yokuvula nokuvala yeI-Valve Yokulawula Izinga Lokushisayisango, futhi indlela yokunyakaza kwesango iqonde ngqo ohlangothini loketshezi. I-Valve Yokulawula Izinga Lokushisa ingavulwa ngokuphelele futhi ivalwe ngokuphelele, futhi ayikwazi ukulungiswa noma ukugoqwa. Isango linezindawo ezimbili zokuvala. Izindawo ezimbili zokuvala zemodi esetshenziswa kakhulu i-Valve Yokulawula Izinga Lokushisa zakha isimo se-wedge. I-engeli ye-wedge iyahlukahluka ngamapharamitha e-valve, ngokuvamile i-5°, kanye ne-2°52′ lapho izinga lokushisa eliphakathi lingekho phezulu. Isango le-Valve Yokulawula Izinga Lokushisa le-wedge lingenziwa libe yi-whole, elibizwa ngokuthi isango eliqinile; lingenziwa futhi libe isango elingakhiqiza inani elincane lokuguquguquka ukuze kuthuthukiswe ubuciko balo futhi kulungiswe ukuphambuka kwe-engeli yendawo yokuvala ngesikhathi sokucubungula. Ipuleti libizwa ngokuthi isango elinwebekayo. Lapho i-Valve Yokulawula Izinga Lokushisa ivaliwe, indawo yokuvala ingavalwa kuphela ngokucindezela okuphakathi, okungukuthi, kuncike ekucindezelweni okuphakathi ukuze kucindezelwe indawo yokuvala yesango esihlalweni se-valve ngakolunye uhlangothi ukuqinisekisa ukuvalwa kwendawo yokuvala, okuzivala ngokwayo. Ama-Valve Okulawula Ukushisa amaningi avalwa ngenkani, okungukuthi, lapho i-valve ivaliwe, isango kumele liphoqwe esihlalweni se-valve ngamandla angaphandle ukuqinisekisa ukuqina kwendawo yokuvala. Isango le-Valve Yokulawula Ukushisa lihamba ngokuqondile nesiqu se-valve, esibizwa ngokuthi i-lift-rod Temperature Control Valve, eyaziwa nangokuthi i-rising-rod Temperature Control Valve. Ngokuvamile, kunezintambo ze-trapezoidal entongeni yokuphakamisa. Nge-nut phezulu kwe-valve kanye nomsele wokuqondisa emzimbeni we-valve, ukunyakaza okujikelezayo kuguqulwa kube ukunyakaza okuqondile, okungukuthi, i-torque yokusebenza iguqulwa ibe yi-operating thrust. Lapho i-valve ivulwa, lapho ukuphakama kwesango kulingana nobubanzi obuphindwe ka-1:1 be-valve, isiteshi soketshezi asivimbeki, kodwa lesi sikhundla asikwazi ukubhekwa ngesikhathi sokusebenza. Ekusetshenzisweni kwangempela, i-top yesiqu se-valve isetshenziswa njengesibonakaliso, okungukuthi, indawo lapho ingenakuvulwa khona, njengendawo yayo evulekile ngokuphelele. Ukuze kucatshangelwe isenzakalo sokukhiya esibangelwa ukushintsha kwezinga lokushisa, ngokuvamile sivulwa siye endaweni ephezulu, bese sibuyela emuva ekujikeni okungu-1/2-1, njengendawo yevalvu evuleke ngokuphelele. Ngakho-ke, indawo evuleke ngokuphelele yevalvu inqunywa ngokuya ngendawo yesango, okungukuthi, ukushaya. Kwamanye amaValvu Okulawula Izinga lokushisa, i-stem nut isethwe esangweni, futhi ukujikeleza kwesondo lesandla kuqhuba i-valve stem ukuthi ijikeleze, okwenza isango liphakame. Lolu hlobo lwevalvu lubizwa ngokuthi i-rotary stem Temperature Control Valve, noma i-dark stem Temperature Control Valve.
