Project Name: Guizhou Tianfu chemical vapor vent valve at
Project time: December 2013
Project location: Guizhou, China
Guizhou Tianfu chemical the steam vent valves were originally used is a domestic regulating valve factory cam around the song valve is to the X-1321A of steam in the emptying valve, the valve position signal is 13XV-0X27 medium is the steam and temperature is 40 degrees Celsius, caliber is DN50 and valve pound class is ANSI 900#, valve before the pressure is 5.0MPA, after the valve is atmospheric pressure. Previously used valve leakage level is ANSI class IV, leakage is large, one to the winter, steaming, not only energy loss, looks is not very ideal. So I decided to change it.
Wuxi Kyle grams (kelk) scheme is a triple eccentric metal hard seal butterfly valve, leakage level is zero leakage, the difficulty lies in the caliber of the valve is relatively small (butterfly valve is usually only do DN80), only DN50, pounds of body level is relatively high body relatively thick, so the flow channel block, design difficulty is very great.
Finally, the design department or to overcome the difficulties, the design of the valve, and applied to practice, to achieve zero leakage, has been affirmed by the customer. Below is a picture of this valve.
