Embodiment Construction

[0016] Attached below Figure 1-2 The present invention will be further described. Such as figure 2 As shown, the top view structure schematic diagram of the new automatic two-way air regulating device. figure 2 The two sides of the center line are the left and right sides of the tee shell respectively.

[0017] A new type of automatic two-way air regulating device, comprising: a main air cylinder, a spare air cylinder, a three-way housing and an air outlet cylinder. An air guide valve 3 for switching air sources is installed inside the three-way housing. The new automatic two-way air conditioning device will figure 1 The traditional "T" shape is improved as figure 2 "Y" shaped tee housing shown.

[0018] The three-way housing 2 is a Y-shaped housing, and the wider end of the three-way housing 2 is equipped with a main air cylinder 4 and a spare air cylinder 5, and the other end is equipped with an air outlet 1, an air cylinder 4, and a spare air cylinder. 5 are respe...

Abstract

The invention discloses a novel automatic bidirectional air regulating device, and provides the bidirectional air regulating device for automatic switching between a local fan and a standby local fanduring normal operation; the maintenance rate of the local fan air regulating device is reduced, and internal air leakage of the regulating device is completely eradicated. According to the followingtechnical scheme, the novel automatic bidirectional air regulating device includes a main hair dryer, a standby hair dryer, a three-links shell body, and a chimney fan, wherein an air guiding valve for switching air sources is installed in the three-links shell body; the novel automatic bidirectional air regulating device is characterized in that the three-links shell body is a Y-shaped shell body, the main hair dryer and the standby hair dryer are installed at the wider end of the three-links shell body, and the chimney fan is installed at the other end of the three-links shell body, and themain hair dryer and the standby hair dryer are respectively connected with a main air blower and a standby air blower; and the air guiding valve is installed between the main hair dryer and the standby hair dryer in the three-links shell body, and a valve baffle of the air guiding valve is installed above a valve baffle seat through an articulated shaft.

Description

technical field [0001] The invention relates to an air guiding device used for fan switching in coal mine underground excavation working face. Background technique [0002] For ventilation of underground local fans in coal mines, an automatic switching test between normal working local fans and spare local fans should be carried out once a day. When switching, local ventilation must not be affected. [0003] Such as figure 1 As shown, when the main and standby local fans are switched, the air guide device consists of two air guide valves, the installation positions are perpendicular to each other, and the intersection angle of the main and backup air ducts is large, so the mechanical accident rate of the air control device is high. There is a risk of air leakage. The three-way housing of the vertical structure of the main air duct and the spare air duct generally has a large ventilation resistance, which reduces the air suction volume of the local fan and reduces the effe...
