Casting iron excavator's wheel
Swing
Check Valve:
The discs tightly cover the rubber with no
iron exposed. The media are pledged clear and pure. The rubber-coating layer of
the discs is added with durable nylon cord fabrics and soft mental cord
fabrics, which greatly improves the discs` capacities of enduring flexing and
stretch when unlocked or closed, meanwhile, prolongs service life.
When in the state of closeness, the discs
form a certain angle with the flowing direction.
The through-holes of the base and the discs
are all oval while the flowing channel is straight- through. Therefore, the
closed angle is relatively small, which decreases phenomena of the water
hammer, as a result, effectively secures the valve.
