Rack and pinion gate

Rack and pinion gate for coal flow shutoff

Category Coal handling plant

Product Details

Function

Rack and pinion gate is installed at raw coal bunker outlet to control feed stream into pulverizer in thermal power plant.

Structure

Rack and pinion gate consists of framework, rack and pinion, slide gate, enclosed casing, speed reducing unit, electric actuator, etc.

Working principle

Electric actuator drives pinion shaft to rotate. Pinion, which is welded to pinion shaft, travels on rack. Then two sliding gates made of thick metal sheet, which are connected with rack, moves horizontally and oppositely inside valve body to start or stop coal flow.

Features

Enclosed structure, no leakage.
Flexible operation, reliable performance.
Easy installation by flange.
Manual control & remote control available.
Sloping design for lower body. Coal lumps can slip into chute easily.

Actuator and transmission is the key components for rack and pinion gate. Geckointech uses excellent parts of high quality to make a perfect delivery.
