Development of Fire-resistant Experimental Device for Valve Flange

Abstract

This paper mainly describes the principle of end fire resistance test equipment and the current research status of valve fire resistance test equipment at home and abroad. In view of the shortcomings of the traditional test device, we made several improvements: 1. We added the burner at the bottom. 2. We added the rail car that can be electrically driven in and out. 3. We optimized the cooling circulation system of the high pressure gas with internal leakage. 4. We improved the overall structure of the valve combustion chamber. 5. We added the end connection bending moment system. The test shows that the temperature, pressure and other performance indicators of the test device meet the relevant requirements of API standards.
