The invention relates to a double-trigger umbrella type oil and gas pipeline explosion-proof valve which comprises a valve body, a support, a valve rod guide rail, a valve rod set, an explosion-proof cover, a left mechanical response mechanism, a right mechanical response mechanism, a locking mechanism and a temperature sensing action mechanism. Valve diameter parts are arranged at the two ends of the valve body, and the valve rod guide rail is arranged between the left mechanical response mechanism and the right mechanical response mechanism. The valve rod guide rail is located in the valve body, the valve rod set surrounds the valve rod guide rail, and the valve rod set is externally wrapped by a layer of anti-explosion cover. The left mechanical response mechanism and the right mechanical response mechanism are centrally installed in the valve diameter parts at the two ends of the valve body through the supports respectively. When a pipeline is burnt or exploded, a limiting disc at one end of the device is unfixed and rapidly moves in the guide rail, the valve rod set is rapidly shrunk, and therefore a valve clack is in an opened posture. When the limiting disc moves to the limit distance, the limiting disc and another limiting disc are locked through a locking block and a locking cavity and cannot move continuously, at the moment, the valve clack is tightly attached to the inner wall of the valve body, flames or shock waves can be blocked, and the explosion-proof effect is achieved.
