Cuplul de Supap\u0103 cu poart\u0103 API600<\/a> este cuplul de deschidere al supapei (cuplul supapei). Unitate: Newton. Metru.<\/p>\n

Cuplul de deschidere, cunoscut \u0219i sub denumirea de cuplu de operare, este cel mai important parametru pentru selectarea dispozitivului de antrenare a supapei. Cuplul de deschidere este, de asemenea, un alt indice important pentru m\u0103surarea calit\u0103\u021bii produselor supapelor. C\u00e2nd oamenii evalueaz\u0103 calitatea supapei, aceasta este adesea descris\u0103 ca deschidere u\u0219oar\u0103 \u0219i flexibil\u0103 a supapei. \u00cen standardele supapelor de conduct\u0103 ale unor \u021b\u0103ri industriale avansate, este considerat unul dintre indicatorii de evaluare \u0219i se prevede c\u0103 cuplul de deschidere al supapei manuale nu trebuie s\u0103 dep\u0103\u0219easc\u0103 360n \u2022 M. Dac\u0103 acest cuplu este dep\u0103\u0219it, este necesar s\u0103 se ia \u00een considerare selectarea dispozitivelor de conducere adecvate (cum ar fi dispozitivele electrice, pneumatice \u0219i hidraulice). Unii produc\u0103tori imprim\u0103 cuplul de deschidere \u00een proba de produs pentru a facilita selec\u021bia utilizatorilor.<\/p>\n

Cuplul de deschidere (cuplul) se refer\u0103 la for\u021ba sau cuplul care trebuie aplicat pentru deschiderea sau \u00eenchiderea supapei. La \u00eenchiderea supapei, este necesar s\u0103 se formeze o anumit\u0103 presiune specific\u0103 de etan\u0219are \u00eentre p\u0103r\u021bile de deschidere \u0219i de \u00eenchidere \u0219i cele dou\u0103 suprafe\u021be de etan\u0219are ale scaunului supapei. \u00cen acela\u0219i timp, este, de asemenea, necesar\u0103 dep\u0103\u0219irea frec\u0103rii dintre tija supapei \u0219i garnitur\u0103, \u00eentre filetele tijei supapei \u0219i piuli\u021b\u0103 \u0219i \u00eentre suportul de cap\u0103t al tijei supapei \u0219i alte p\u0103r\u021bi de frecare. Prin urmare, trebuie aplicate o anumit\u0103 for\u021b\u0103 de \u00eenchidere \u0219i un cuplu de \u00eenchidere. For\u021ba de deschidere \u0219i \u00eenchidere \u0219i cuplul de deschidere \u0219i \u00eenchidere cerute de supap\u0103 \u00een procesul de deschidere sunt modificate, iar valoarea maxim\u0103 este \u00een momentul final al \u00eenchiderii sau momentul ini\u021bial al deschiderii. C\u00e2nd proiecta\u021bi \u0219i fabrica\u021bi supape, \u00eencerca\u021bi s\u0103 reduce\u021bi for\u021ba de deschidere \u0219i \u00eenchidere \u0219i cuplul de deschidere \u0219i \u00eenchidere.<\/p>\n

Cuplul de deschidere poate fi calculat sau m\u0103surat pentru a ob\u021bine rezultate aproximative, sau m\u0103surat cu cheia dinamometric\u0103.<\/p>\n
