Abstract

The invention discloses a ventilating fan three-way valve. The ventilating fan three-way valve comprises an air inlet, an A air outlet, a B air outlet, a box, a rotary shaft and a rotary baffle. The ventilating fan three-way valve is characterized in that the box is provided with the air inlet, the A air outlet, the B air outlet and the rotary shaft; the rotary baffle is arranged in the box; the rotary shaft is welded in the middle of the rotary baffle; the rotary shaft is connected with a chain plate; a rocking handle provided with a screw thread is arranged on the chain plate; a fixing nut is welded on the box; and by rotating the rocking handle, the baffle can be driven to rotate, the screw thread of the rocking handle is screwed into the fixing nut after reaching a predetermined position, the baffle is fixed, and air guiding is achieved. The ventilating fan three-way valve has the beneficial effects that operation is easy, time and labor are saved, and safety and reliability are guaranteed.

Description

technical field [0001] The invention relates to a mine ventilator three-way valve. Background technique [0002] At present, in the tunnel construction, there are many types of ventilation for the driving face of the roadway. Some use rotation to advance, and ventilation also uses two roadways to supply air in turn. It is necessary to configure three ventilators. The original method used to control the air supply in turn is the method of bundling the ventilator or inserting the plate. There are certain difficulties in the operation, the intensity is high, laborious and time-consuming, and the air duct is suspended on the top of the tunnel, so the operation has certain unsafety. Contents of the invention [0003] The object of the present invention is to provide an easy-to-operate ventilator three-way valve in order to overcome the deficiencies of the prior art. [0004] In order to realize the above object, the technical scheme adopted by the present invention is: [0...
