The difference between the micro-Kai and the Kai-type safety valve
What is the difference between micro-Kai and Kai-type safety valve What is the micro-Kai-type safety valve is the degree of opening of the safety valve is a trace, does not allow sudden opening or closing of the "water hammer" phenomenon, mainly for liquid media; he The typical feature is the same import and export caliber. What is the full safety valve when the valve core is raised to the annular area of ​​the valve seat and the seat area equivalent to the inner diameter (increased height × spool sealing surface area generated by the circumference = valve sealing surface area ), Is all open; its typical feature is the export diameter greater than the import diameter. First, the whole Kai-type safety valve and the micro-Kai-type safety valve is the difference between its open height, the general opening degree of the micro-valve safety valve seat throat diameter of 1/20 ~ 1/40, and all Kai-type safety valve opening height of the valve seat throat diameter of more than 1/4. Second, the selection of precautions: a, safety valve emissions must be greater than the safe discharge of containers; b, the operating pressure requirements of the container is absolutely smooth, should consider the use of micro-Kai safety valve (such as the compressor cylinder); c, high pressure Containers, large containers and large volume of safe discharge, the best choice of all-relief valve (such as reactor type equipment). Third, the safety valve opening height refers to: the valve flap to leave the closed position of the actual lift.
