Abstract

"MéTODO E APARELHO PARA LIBERAR VáLVULAS EMPERRADAS". Aparelho para liberar uma válvula emperrada tendo uma haste atuadora de válvula (10) que se projeta para fora da válvula compreendendo meios para repetidamente aplicar uma força de impacto à haste atuadora de válvula ao longo de seu eixo geométrico longitudinal. A força de impacto pode ser aplicada alternadamente em direções opostas ao longo do eixo geométrico longitudinal e o aparelho pode compreender meios de aperto para apertar e engatar uma porção projetante da haste atuadora de válvula. A aplicação repetida da força de impacto sobre a válvula ao longo de seu eixo geométrico longitudinal induz vibrações e provoca um movimento das porções da válvula que causam emperramento. Isto ajuda em desalojar carepas e outros depósitos, liberando a válvula.
