摘要： A biased safety valve for preventing the flow of materials therethrough in the presence of predetermined conditions is disclosed. Resilient means urges an outlet closure member upstream away from the outlet. When the predetermined conditions have been met, the closure member overcomes the resistance of the resilient means and is seated against the outlet to prevent further flow therethrough.

摘要： A safety valve for preventing the flow of materials therethrough in the presence of a predetermined external temperature condition is disclosed. A fusible plug maintains a spring-biased closure member out of contact with a seat in the outlet path. Upon melting of the fusible material, the closure member is released and urged into contact with the seat in the outlet path to prevent any further flow of material therethrough.
