Widely used in hydraulic gate hydropower, municipal construction, water supply and drainage, aquaculture, agricultural water conservancy construction and other projects, mainly in the steel gate of welded steel plate to the substrate, the gate can be closed corrosion-resistant rubber seal, sealing degree. The shutter may be increased according to the head pulley grooves, positioning wheel, in order to reduce friction, to facilitate lifting off. Gate Features: 1. iron gate by the door, gate, rails, seals, drive screw, nut hanging block / lug and adjustable sealing mechanism and other components, including door frames and shutters are made of quality gray cast iron or ductile Guangzhou made of cast iron gates, rails arranged symmetrically with stainless steel bolts and dowel pins and frame two side ends of the connection (for small and medium caliber of the gate, which can be used with the door frame rail pouring into one), rail length is generally full gate opening height of 1 / 2 ~ 1/3, and thus the overall structure of high-strength, high rigidity, abrasion resistance, corrosion resistance, high pressure capability. Iron gate works and use of the structure in a certain sense gate, iron gate works and their structural characteristics influence each other, interrelated, because of it so it works requires a corresponding structure, because of it have such a structure to form a corresponding principle, first look at the iron gate works: When the gate and door frames installed in the underwater site, the rail is mounted on the upper end of the steel gate door, to ensure that the door to work, along door frame, the rail in a certain stroke for the upper and lower vertical reciprocating motion. Work, turn the crank hoist (electric hoist, simply pushed the control box power switch button) the nut or screw worm wheel rotates, the screw drive transmission work, so the door up and down relative to the frame reciprocates At the same time, the use of wedge wedge device can be tight loose works gate prices, door drops to the set limit position, door frames, door seal seat surface can effectively fit, play a role in water cut.
