specific Embodiment approach
[0056] The gas path control system 21 of the present invention is connected with two dampers through two gas paths to realize the functions of opening, closing and interlocking. The specific implementation is as follows:
[0057] Such as figure 1 , image 3 , Figure 4 As shown, the air source enters the air source processing element 2 through the main intake valve 1, and is delivered to the entire system after being filtered and processed. In the air path A, when the first two-position three-way hand valve 5 in the air path A and the second two-position three-way hand valve 4 (corresponding to the front and rear sides of the damper) are opened, the control air path of the first damper is connected, and there are two results:
[0058] (1) After the air source reaches the big 2-position 5-way blocking valve 6 of the air circuit A, the big 2-position 5-way blocking valve 6 changes direction, and the gas source is sent to the second working port B of the big 2-position 5-way bl...

The invention discloses a full-servo safety interlocking air door. The full-servo safety interlocking air door comprises two air door bodies, wherein each air door body comprises two door columns, a left door leaf and a right door leaf are symmetrically mounted between the two door columns, the left door leaf and the right door leaf are arc-shaped door leaves of the same structure, and a plurality of transverse ribs are arranged on the arc-shaped door leaves from top to bottom; a top box is mounted above each door column and comprises a rectangular frame and a triangular frame which are fixedly connected into a whole, the length of the rectangular frames is equal to the width of the air door bodies, the width of the rectangular frames is equal to the width of the door columns, and the vertex angle alpha of each triangular frame is 140 degrees; the full-servo safety interlocking air door further comprises two groups of pneumatic assemblies used for driving the left door leaf and the right door leaf and a set of air path control system used for controlling the pneumatic assemblies, and the two air door bodies are opened, closed and interlocked through the air path control system. The invention further discloses the full-servo safety interlocking air door and a control method. The problems that door leaves and door bodies of existing mine air doors are prone to deformation, elements are prone to damage, and two air door bodies cannot be interlocked can be solved.
Description
technical field [0001] The invention relates to the technical field of underground ventilation control, in particular to a full-servo safety interlock damper and a control method. Background technique [0002] In order to have a good air environment and safe production requirements in the mine, there are large-scale ventilation equipment at the wellhead of the coal mine to forcibly supply air to the underground, and the fresh air sent fills the entire mine. There are two dampers for each damper, which can avoid the loss of air supply. The traffic rule of the two doors is that only one of the doors can be opened to pass, and the other door must be closed. When pedestrians or vehicles enter from either side of the roadway , one of the air doors is open, and the other air door needs to be closed. When one of the air doors is closed, the other air door can be opened to prevent both doors from being opened, causing a short circuit of the air flow and causing a safety hazard, whic...
