Tongwenhong of Xingtai zhengruntong Technology Co., Ltd. believes that it is the only enterprise in China that has mastered the manufacturing technology of normally closed shut-off valve. After four years of technical research, the explosion-proof emergency shut-off valve independently developed by it has won a number of national invention patents, filling the domestic gap. This safety assurance device is linked with the liquid level meter, combustible body alarm and other relevant safety instruments. In case of an emergency in the fuel oil depot, gas depot or hazardous chemicals depot, as long as the power supply is cut off, it can be automatically closed in 10 to 30 seconds, so as to prevent the accident from escalating again (generally, it takes about 10 minutes for the manual stop valve to close, and about 2 minutes for the electric stop valve). At present, the products have been widely used in the systems of PetroChina and Sinopec. Another 14.2% of the bridges are too outdated in function.
