Applications:
The man hole cover is mainly used for tanks in the fields of food,beverage,chemical,etc.
Operating principles:
The manhole cover is in the closed position, and the handwheel carried by the spring can ensure its safety. The handwheel and the seal in the cover together can ensure complete airtightness. The lid is attached to the frame by a strong hinge, thus allowing the lid to fall into place when closed. The hinge is also designed to limit the opening of the lid to 30° above the vertical position for the opening time.
Design and features:
Pressure manhole covers have 4 to 18 handwheels. The number of bolts depends on cover size, pressure, temperature, etc. The seal between the cover and the bracket is placed in the cover.
