The invention discloses a multiple ventilation flow partition control valve for coal mine ventilation and mainly relates to the technical field of coal mine ventilation. A main air pipeline, a valve body assembly, a first roadway ventilation pipe, a second roadway ventilation pipe and a third roadway ventilation pipe are included; the valve body assembly comprises a round valve cavity, a center shaft, a first sector-shaped valve switch and a second sector-shaped valve switch; the center shaft is arranged at the position of a circle center shaft of the round valve cavity, and provided with a first hub motor and a second hub motor; the first hub motor is used for controlling rotation of the first sector-shaped valve switch; the second hub motor is used for controlling rotation of the secondsector-shaped valve switch; and the first sector-shaped valve switch and the second sector-shaped valve switch are each provided with a ventilation hole. The multiple ventilation flow partition control valve for coal mine ventilation has the beneficial effects that the multiple ventilation flow partition control valve for coal mine ventilation is suitable for adjustment for guiding and partitioning off air flow on a multi-way roadway, and is an electronic control simple and practical air flow guiding and partitioning control valve.
Description
technical field [0001] The invention relates to the technical field of coal mine ventilation, in particular to a multi-ventilation flow interruption control valve for coal mine ventilation. Background technique [0002] The basic task of mine ventilation is to supply enough fresh air underground to meet the needs of personnel for oxygen; to dilute harmful gases and dust underground to ensure safe production; to adjust the underground climate and create a good working environment. [0003] In order to distribute the underground air flow along the designated route, it is necessary to build structures that guide and control the air flow in certain roadways, that is, ventilation facilities, which are divided into facilities that guide the air flow and block the air flow. For multi-pass roadways, the current facilities for guiding air flow and blocking air flow are relatively backward. There is no easy-to-use, special air flow blocking control valve to adjust the guiding air flow...
