WYM inclined wind shaft explosion-proof door product introduction
WYM inclined air shaft blast doors are special sealed manhole covers installed on the exhaust wellhead where the main ventilator is installed. In normal ventilation, it is used to isolate the underground airflow from the surface atmosphere, prevent the air flow from short circuit, and ensure the normal ventilation system. When a gas or coal dust explosion accident occurs in the underground, the explosion-proof door is opened by the impact of the explosion, so that the explosion air flow is directly discharged to the surface atmosphere, plays the role of pressure relief, and prevents the main ventilator from being damaged by the impact of the explosive air flow; When the main ventilator is not operating, the blast door can be opened to ventilate using natural air pressure.
The function of WYM inclined air shaft explosion-proof door is that when an explosion occurs in the mine, the shock wave will rush the door outward, which plays the role of releasing and alleviating the shock wave of the inclined wind shaft.

Working environment of WYM inclined wind shaft explosion-proof door

The WYM inclined air shaft explosion-proof door body is used for ventilation with a maximum negative pressure of 350 mm water column, and the fan is a withdraw-out type.  The equipment is suitable for the roadway of the inclined air shaft in the underground coal mine. The operator opens the damper by manually removing the welded steel pipe; Welded steel pipes should be used when the wind is reversed, and they should not be used during normal operation, and they should be properly preserved; When there is a backwind, the welded steel pipe must be placed on the deadbolt socket when closing the door.
Product structure of WYM inclined wind shaft explosion-proof door
WYM inclined wind shaft explosion-proof door is composed of door frame, door leaf and anti-wind device.
(1). The door frame is divided into symmetrical parts, and each piece is an angle steel group welded frame member.
(2). The door leaf is welded by steel plate, tic-tac-toe distribution angle steel, etc.
(3). The anti-wind device adopts steel pipe plugging.
