Hydraulically driven grille type gate valve

Abstract

The invention discloses a hydraulically driven grille type gate valve, and relates to a hydraulically driven grille type gate valve for controlling delivery of powder. A hydraulic driving head device is mechanically connected with a connecting rack by a bolt, a flat gasket, an elastic gasket and a nut. A hydraulic driving head core shaft sleeve is mechanically connected with a hydraulic driving head core shaft. The hydraulic driving head device is electrically connected with an electric control device. The grille type gate valve consists of the hydraulic driving head device, the electric control device, a gate valve body, a gate plate and a transmission device. When the gate valve is opened and closed, the travel of the gate plate is only one third of that of the gate plate of the conventional gate valve; the gate plate slides in the gate valve body, and a threaded sleeve connected with the gate plate in the transmission device slides under the action of a sealing ring, so the powder in the gate valve body cannot leak to the outside and cannot enter a barrel of the transmission device to affect normal operation of a screw, the threaded sleeve and a bearing. The grille type gate valve is simple in structure, convenient to install and low in cost. The hydraulically driven grille type gate valve can be operated in a long distance so as to protect the body health of workers.

Description

Technical field: [0001] The invention relates to a hydraulically driven grid-type gate valve for controlling powder conveying. Background technique: [0002] At present, powder silos and powder conveying pipelines generally use the opening and closing gate valve to control the powder transportation. Traditional gate valves have the disadvantages of long gate stroke, slow opening and closing speed, poor gate sealing, prone to dust leakage and exposure. The transmission parts of the machine are easily blocked by dust, resulting in difficult rotation and other defects, which bring a lot of inconvenience to the operator and even affect production. Manual operation brings fatigue to the workers and is polluted by close-range dust. Invention content: [0003] The purpose of the present invention is to provide a hydraulically driven grid-type gate valve, which overcomes the slow opening and closing speed of traditional gate valves, poor gate sealing and easy dust leakage, and exp...

Problems solved by technology

[0003] The object of the present invention is to provide a hydraulically driven grid-type gate valve, which overcomes the slow opening and closing speed of the traditional gate valve, poor gate sealing, easy dust leakage, and exposed transmission parts are easy to be blocked by dust Due to technical defects such as difficulty in rotating the net, it has the characteristics of short stroke of the gate, fast opening and closing speed, tight seal of the gate without dust leakage, grease lubrication for transmission parts and dust separation seal, light and fast operation
