Abstract

VÁLVULA REGULADORA OCA. Para fornecer uma válvula reguladora oca tendo um efeito de redução de calor melhorado. Em uma válvula reguladora oca (10) tendo uma cabeça de válvula (14) e uma haste (12) integral com a cabeça de válvula (14), a válvula reguladora oca (10) é formada com uma cavidade interior S que se estende na cabeça de válvula (14) e a haste (12). A cavidade interior S é carregada com um refrigerante (19) e um gás inerte. A cavidade interior S tem uma cavidade interior geralmente em forma de disco S1 e uma cavidade de haste interior S2 formada na haste (12) e conectada à cavidade de cabeça de válvula interior S1 em um ângulo reto. Durante um movimento recíproco da válvula (10), um fluxo convectivo vertical de refrigerante (19) ao longo do eixo L da válvula (10) é estabelecido pelo menos na cavidade de cabeça de válvula interior S1, aumentando assim o seu efeito de redução de calor.
