Why is the plane steel gate good quality and durable? In this paper, a brief introduction is given to this problem: the control facilities of planar steel gates for closing and opening drainage channels are an important part of hydraulic structures, which can be used to intercept water flow, regulate flow, control water level, discharge sediment and floats, etc. Why is the plane steel gate good quality and durable? The steel gate is used to close and open the control facilities of drainage channels. It is an important part of hydraulic structures. It can be used to intercept water flow, regulate flow, control water level, discharge sediment and floats, etc. The gate blades of planar steel gates include: load-bearing structure, walking support, supporting arm, supporting hinges, water stopping device, lifting lugs, etc. The embedding part of plane steel gate includes track, hinge seat, water stop seat, angle guard, etc. The planar steel gate has the advantages of light weight, good corrosion resistance, good water-proof performance, good anticorrosion performance, long service life, bidirectional compressive stress condition and good sealing performance. The water-crossing section and channel of the planar steel gate are equal in width; the ultra-wide gate can be made into a double-hanging point opening and closing, which has strong adaptability to the depth of the channel; and the rubber seal. Planar steel gate consists of three parts: movable part (also known as gate blade), buried part and hoisting mechanism. Steel gate can be used to control the flow of water, steam, oil, gas, mud, corrosive medium, liquid metal and radioactive fluid, etc. The working pressure of the valve can be from 0.0013 MPa to 1000 MPa of ultra-high pressure. The manufacturer of steel gate hydraulic dam, Yantai Tiansheng Science and Technology, can realize continuous decontamination and complete decontamination in water section. The rake linear speed is 6 m/min, and the cleaning efficiency is high. The lattice beam supports the concrete foundation to make the cleaning machine run smoothly and work reliably. Insert the grille at the top of the grille, take the dirt to the top of the sweeper, complete the reverse unloading action, and keep the water section clean and clean. The motor is invisible in the frame, the protection effect is good, and the barrier-free decontamination is realized. Stainless steel traction chain ensures no rust and maintenance. The anticorrosion scheme is sand blasting and rust prevention + hot spraying zinc + epoxy varnish primer + epoxy mica iron intermediate paint + chlorinated rubber top paint, with protection capacity exceeding 20 years. Performance characteristics of cleaning machine: grille valve body, rotary gear harrow, transmission mechanism, overload protection mechanism and stainless steel traction chain, etc. The ambient temperature should not be less than 10 C and the relative humidity should not be more than 60%. The construction should not be carried out in windy or foggy weather. Primer painting should be carried out as soon as possible after the surface of steel is cleaned up. Primer painting should be finished in 4 hours in humid environment and not more than 12 hours in sunny and better weather. Paint brushing should be uniform and thoughtful, not to be omitted. The appearance of the upper coat should be checked before each coat is painted. If there are defects such as leakage, falling, wrinkles, etc., it should be dealt with in time. After finishing, the next coat should be constructed. Summarize steel gate hydraulic dam manufacturer, hoisting hoist is widely used in water conservancy project gate opening and closing, it is the matching machinery of water intake and withdrawal sluice, such as farmland irrigation, aquaculture, agricultural economic development zone, sewage treatment plant, water power station, reservoir (sluice, dike, tunnel, pipeline), etc. It can be used in mountainous area, plain area with or without electricity.
