Fixed wheeled round steel gate with a flat-screen slide gate advantage of differences, move the slider to scroll consequent lower friction coefficient. Flat slider-style round gate by the door leaf frame, rubber seal, lock beams, sliders, etc., in addition to sealing sealing round gate, the left and right ends of the beam is not locked when required maintenance, support in the circle gate gate slot , the slide using oil nylon, corrosion of steel having a third coefficient of friction. Round gate by the door, gate, rails, seals, drive screw, nut hanging block / lug and adjustable sealing mechanism and other components, rails are arranged symmetrically with stainless steel bolts and dowel pins and frame two side end connection (for small caliber round gate, pouring its rails and door frame into one), rail length is generally circular gates wide open height of 1/2 to 1/3, and thus the overall structure of the gate round of high strength, high rigidity, wear resistance, corrosion, pressure capacity.
Inlaid copper iron gate through circular wedge wedge device to seal, seal or rubber material is copper alloy and precision machining after with research, it is a good seal.
Cast iron flap valve with inlaid copper round hoist supporting the use of the gate as the working part of the hoist gates open and close the circle of the operative part, which open or close the gate to reach the water, turn off the water or the water level regulation purposes.
Round gate, gate fixed wheeled round, round cast iron copper inlay gates, iron gates flat slider-style round copper inlay side gate is mainly used for water supply and drainage, flood control, irrigation, water conservancy and hydropower project, is used to cut-off, dredging or regulate water flow The role of water.
1, the doors, door frames, etc. made of gray cast iron (or iron) made of high structural strength, good corrosion resistance, bearing capacity (positive pressure 0.1MPa)
2, the sealing surface of bronze precision machining, sealing, and a small amount of water seepage: Forward 0.72L/mxmin reverse 1.25l/mxmin
3, complete varieties, wide application, easy installation.
Cast shoot the door open with a one-way flow forward and backward off effect. Counterweight shoot the door by means of counterweight balancing role in the water under the action of the page automatically open or close the door, or a little external force to open or close the door page; pontoon shoot the door then use the leaf in water buoyancy in the water under the action page open or close the door.
Cast steel shot door into round and square shoot the door-to-door, knock on the door for drainage and sewage disposal works of the various pipes and water channels as an overflow, the non-return purposes, but also for a variety of shaft covers, it is used only unidirectional flow outlet structure characteristic round shoot the door open with a one-way flow forward and backward off effect. Counterweight shoot the door by means of a balanced counterweight role in the water under the action of the page automatically open or close the door, or a little external force to open or close the door page; pontoon-door door leaf is applied in water buoyancy in the water under the action page open or close the door.
1, with weight-door advantages and defects;
1) simple structure, reliable work;
2) Door opening page with counterweight balancing demand;
3) door leaf is closed, the impact is large, easy to damage the valve seat.
2, pontoon-door advantages defects;
1) gantry structure and distribution remake door, the door seal chamber constructed pages, doorway pages specific gravity of 1.2-1.5;
2) No suspension configuration counterweight;
3) door leaf is closed wallop.
