Technical Problem

[0004]针对现有技术的不足，本申请提供了矿浆输送管道用防腐耐磨闸阀，解决了一体化设计闸阀在矿浆严苛工况下长期使用损坏后，因各结构紧密装配关联无法单独更换部件，需整体拆卸更换，导致维护成本高、造成资源浪费，不符合行业节能降耗趋势的问题

Benefits of technology

[0022]This corrosion-resistant and wear-resistant gate valve for slurry conveying pipelines, through the design of a limit ring, protective cylinder, observation plate, sleeve, and positioning plate, protects the threaded rod during use. The protective cylinder and observation plate prevent the threaded rod from contacting the external environment, thus preventing rust and affecting the valve's operation. The sleeve secures the positioning plate to the threaded rod, allowing the positioning plate to rise and fall with it. After the positioning plate has risen or fallen, the user can observe its position inside the protective cylinder through the observation plate and its height through the scale lines inside the protective cylinder. This eliminates the need for users to rely solely on experience to turn the handle or forcibly turn it to its limit, preventing damage to the threaded rod and avoiding incomplete opening or closing of the gate valve, thus improving safety and operational accuracy.

Abstract

The application relates to the technical field of ore pulp conveying, and discloses a corrosion-resistant and wear-resistant gate valve for an ore pulp conveying pipeline, which comprises a valve body, a fixed shell fixedly connected to the outer side of the valve body, a sealing shell arranged at the top outer side of the fixed shell, a rotating column rotatably connected to the inside of the sealing shell, a threaded rod screw-connected to the inside of the rotating column, a mounting seat fixedly connected to the bottom end of the threaded rod, a gate plate fixedly connected to the bottom of the mounting seat, a rotating disc fixedly connected to the outer side of the rotating column, a rotating handle fixedly connected to the outer side of the rotating disc, two retaining rings fixedly connected to the inside of the valve body, and the two retaining rings being arranged on the two sides of the gate plate. The corrosion-resistant and wear-resistant gate valve for the ore pulp conveying pipeline solves the problem that, after the integrated design gate valve is damaged after long-term use under harsh working conditions of ore pulp, the components cannot be replaced individually due to the close assembly and association of various structures, the gate valve needs to be replaced as a whole, the maintenance cost is high, resources are wasted, and the problem does not conform to the energy saving and consumption reduction trend of the industry.
