    摘要: A thermally activated valve is disclosed for attachment to a pressurized vessel such that substances contained therein can be released at a selected temperature value. The valve includes a body having an inlet and an outlet in fluid communication with each other. The inlet fluidly communicates with the interior of the pressurized vessel while the outlet is in communication with an area having a lower pressure value. Secured in the outlet is an insert having a stem. The stem has a helical groove formed about its outer periphery and has at least one small aperture which is in communication with the helical groove. The insert cooperates with the body to form a helical passageway therethrough. Positioned within the helical passageway is a material for normally blocking fluid flow therethrough which is fusible at a selected temperature to permit fluid flow therethrough. The helical passageway cooperates with the small aperture formed in the stem to extend the life of the valve by inhibiting the extrusion of the fusible material.

    摘要: A combination thermal or pressure activated relief valve is disclosed. The valve includes a housing having an inlet and an outlet formed therein. The inlet is adapted to be attached to a pressure source while the outlet is in communication with an area having a lower pressure value than said pressure source. An insert is secured in the outlet and includes a stem having a first passage formed therethrough and a helical groove formed about its outer periphery. The groove cooperates with the housing to form a helical passageway between the inlet and the outlet. A fusible material is inserted into the helical passageway and normally blocks fluid flow therethrough and is fusible at a selected temperature to permit fluid flow therethrough. A second member is secured to the insert and has a passage formed therethrough which communicates with the first passage formed in the insert. A pressure responsive lamina is positioned across the passage for normally blocking fluid flow therethrough. The lamina is rupturable in response to a selected pressure arising at the pressure source so as to permit pressurized fluid to be released to the lower pressure area.
