Maintenance and maintenance of breathing valve once a month and twice a month in winter.Its method: first open the valve cover slightly, take out the
Work discharge is a loss due to man-made loading and unloading.As a result of loading, when the pressure in the tank exceeds the release pressure, the
Respiratory emissions from fixed-top tanks can be estimated using the following equation:
LB=0.191×M(P/(100910-P)^0.68×D^1.73×H^0.51×Delta T^0.45×FP×
Respiratory valves are used more and more widely, and oil-sealed breathing valves with forced lubrication have appeared.An oil film forms between the
The self-sealing breathing valve is tightly sealed between the plug and the plug by the pressure of the medium itself.The small head of the plug exten
Packed breathing Valves seal plugs and plugs by pressing the packing.Good sealing performance due to packing.Usually this type of breathing valve has
Tightened breathing valves are commonly used in low-pressure through-line pipes and their sealing performance depends entirely on the fit between the
