Main Features and Uses
In recent years, with the continuous mining of deep wells in coal mines, the impact of underground heat damage on production has increased, and centralized cooling equipment for mines has also been continuously adopted. At present, the commonly used method is to use a gate valve to adjust the flow rate on the branch channel between the mining area or the coal seam. However, the pipe is arranged at the top of the tunnel, and the valve on the pipe manually opens, closes, and adjusts the opening degree is difficult. Not only fine adjustment, and long-term use can easily lead to tight and leakage.
The downhole cooling regulator for the MT947H mine is designed and developed for the coal mine and plays a role in regulating the flow and pressure of each branch. The main features are high adjustment accuracy, uniform flow distribution to the pipeline system, convenient control and adjustment, can achieve remote control in the control box, and the adjustment data far to the set control system, real-time observation of the adjustment.
