Working Principle and Structure
Type TY is made of cast-iron, good in corrosion resistance, simple in structure. When the higher sealing at closed state is needed, the seal made of bronze can be inlaid on the gate frame. But the width couldn't exceed 2m.
Type TYZ is a steel structure with rubber seal. It can stop water on three sides. It isn't limited by the specification and is suitable for optional places. It can have a long life if it made of stainless steel.
Type TYX has fine seal effect; it almost reaches" zero leakage" state. The usable width can reach more than 5m; but the water level adjusted is less than 800mm; especially suitable for the sewage drainage in the alternatively working oxidation ditch, or for the distribution in large type of distributing well The headstock gear is specially matched for it. Please note the start- stop mode is hand or electric, start-stop devices are not necessary to specially choose.
