Advantage of the present invention: (1) this reasonable in design, intensity is good, and high density polyethylene (HDPE) material has corrosion resistance, mar proof, uses this material to improve the application life of gate, becomes semipermanent product;
(2) proportion of high density polyethylene (HDPE) material is 0.95, compared with irony gate, light about 1/3;
(3) during manual operation, because flashboard is light, processing ease, is convenient to administer and maintain repairing;
(4) structure of double disc and the design of ribs, add the Rigidity and strength of gate, is applicable to place or the Gate of the depth of water;
(5) because material itself has corrosion resistance, when restarting after Long-time Shut-down, initial stage load is not had;
(6) lock chamber material is high density polyethylene (HDPE) and ethylene propylene diene rubber, and sealing effectiveness is maximized;
(7) because material is light, open-close sluice gate required electric power is few, greatly saves the year required electricity charge;
(8) because material is light, chemical anchors can be used to install, save set-up time and mounting cost;
(9) generation polluted water quality after the corrosion of steel gate, high density polyethylene (HDPE) material is that macromolecular material long period of soaking can not pollute water source in water.
