This invention provides a pressure relief check valve and a vulcanization shaping pipe assembly for rubber tire vulcanization. The pressure relief check valve has a first channel and a third channel connecting the valve cavity, and a second channel connecting the air release channel and the third channel, all on the valve stem. A first sealing element with a conical outer circumference is provided, with the smaller diameter end of the first sealing element facing the air inlet channel. In this way, nitrogen entering through the air inlet channel can compress the conical outer circumference of the first sealing element and enter the valve stem through the first channel, thus achieving air intake. When air intake ends and the pressure in the pipe connected to the valve stem is too high, nitrogen can flow back to the valve cavity through the first channel, and then sequentially through the third channel and the second channel before entering the exhaust channel. In this way, pressure relief can be achieved through the exhaust channel without the need for a nitrogen balancing valve, thus not affecting the service life and accuracy of the nitrogen balancing valve on the pipeline.

This invention discloses a preheating and temperature compensation method, system, medium, equipment, and product for a compressed air energy storage system's heat storage tank in the field of compressed air energy storage technology. The method includes: during cold start-up of the compressed air energy storage system, high-temperature air from the air compressor outlet and the heat storage medium are introduced into the expansion-side heat exchanger. A staged heating strategy is used to exchange heat between the high-temperature air and the heat storage medium, raising the heat storage medium to the target temperature. After preheating, the high-temperature water tank is switched to operating mode, and the low-temperature water tank is switched to standby mode for temperature compensation. During heat storage, if the temperature difference between the high and low-temperature water tanks exceeds a temperature threshold, or the pressure difference between the high and low-temperature water tanks exceeds a pressure threshold, a nitrogen balance system is used to adjust the nitrogen flow rate and nitrogen injection volume to achieve dynamic temperature balance. During heat release, if the inlet air temperature of the expansion-side air-water heat exchanger is lower than the heat release temperature threshold, an auxiliary electric heater is activated for supplementary heating.
