Primul tip este o capot\u0103 de tip \u0219urub, care este conectat\u0103 printr-o suprafa\u021b\u0103 concav-convex\u0103 \u0219i este f\u0103cut\u0103 dintr-o band\u0103 de o\u021bel inoxidabil \u0219i o garnitur\u0103 flexibil\u0103 de grafit \u0219i poate fi conectat\u0103 \u0219i printr-un inel dup\u0103 cum este necesar.
\nAl doilea tip este o capot\u0103 sudat\u0103 care este sudat\u0103 prin etan\u0219are a filetului \u0219i poate fi sudat\u0103 direct dup\u0103 cum este necesar.
\nAl treilea este o capot\u0103 cu autoetan\u0219are care este filetat\u0103 \u00een capacul cu autoetan\u0219are.<\/p>\n
Supapele din o\u021bel forjat trec adesea cu vederea problema injec\u021biei de gr\u0103sime. Dup\u0103 ce pistolul de unsoare este alimentat, operatorul selecteaz\u0103 supapa \u0219i metoda de injectare a gr\u0103simei dup\u0103 supapa de \u00eenchidere la temperatur\u0103 joas\u0103, apoi efectueaz\u0103 opera\u021bia de umplere cu gr\u0103sime. Exist\u0103 dou\u0103 cazuri: pe de o parte, cantitatea de gr\u0103sime este mai mic\u0103 dec\u00e2t cea a gr\u0103simii, iar suprafa\u021ba de etan\u0219are este accelerat\u0103 de lipsa lubrifiantului. Pe de alt\u0103 parte, injec\u021bia excesiv\u0103 de gr\u0103sime provoac\u0103 risip\u0103. Nu exist\u0103 un calcul precis al diferitelor capacit\u0103\u021bi de etan\u0219are a supapelor pe baza categoriei de tip de supap\u0103. Capacitatea de etan\u0219are poate fi calculat\u0103 \u00een func\u021bie de dimensiunea \u0219i tipul supapei, iar o cantitate adecvat\u0103 de unsoare poate fi injectat\u0103 \u00een mod rezonabil.<\/p>\n
