Explosion venting valve Applicable scope This kind of explosion venting valve is mainly apply for building materials, metallurgy, chemical industry, power plant and so on. Main technical parameter Nominal diameter Apply for bursting calculated pressure (absolate) Applicable temperature Applicable medium Material of valve body DN(mm) PN(Mpa) 300~1000 To be designed Not less than 350℃ Compressed explosive gases Carbon steel Working principle The explosion valve consists of valve body, rupture disc, holder/support, valve cover, heavy hammer and other parts. The rupture disc is in the middle of clamp holder and connected with valve body by bolt. When the system overpresses, the rupture disc will rupture. At the instant moment of relieving pressure, the valve cover will reset after upspringing under gravity action to prevent fire spread. When the valve change rupture disc, the valve body and clamp holder should be lifted upwards. Outline drawing
