Description
Technical field
The invention belongs to Electrical Control Technology, relate to a kind of air door control and use the gas control device.
Background technology
According to " safety regulations in coal mine " requirement; Between advancing under the coal mine, the returnairshaft and mainly advance, each connection roadway that need use between the return aircourse must install the twice air door that reciprocal interlocks; The twice air door that reciprocal interlocks can be a closed condition simultaneously; When one air door was opening, another sect must be a closed condition.Prevent that like this two are opened simultaneously, cause the air inlet system short circuit, cause the mine ventilation accident.The non-pressure damper control device adopts automatically controlled or hydraulic control at present, necessary electricity consumption, and cost is also high, and potential safety hazard is big, and result of use is not ideal enough.
Summary of the invention
The present invention provides a kind of air door esy to use, safe and reliable control to use the gas control device in order to remedy the deficiency of prior art.
The present invention realizes through following technical scheme:
The gas control device is used in air door control of the present invention; Its special character is: comprise the source of the gas case that is arranged on A door one side and the control cabinet of opposite side; And the source of the gas case of B door one side and the control cabinet of opposite side; Comprise that also cylinder and locking on the door body that is separately positioned on A door and B door detect the magnetic control valve, source of the gas case and control cabinet are equipped with door open button, door close button and emergency pressure relief hand valve; Air line is connected under source of the gas case primary air inlet and the mine, after source of the gas case filtration treatment, links to each other with control cabinet through secondary air feed tracheae; The door open button of source of the gas case, door close button and emergency pressure relief hand valve are connected with the corresponding part of control cabinet; Cylinder on the door body and locking detect the magnetic control valve and link to each other with control cabinet the corresponding interface, and the control cabinet of A door is controlled out with the control cabinet locking of B door, incoming interface is connected for crossing one another.
There is air gauge described source of the gas case top.
The invention has the beneficial effects as follows that no any circuit devcie is thoroughly avoided the potential safety hazard at high fiery colliery in the whole system, substitute automatically controlled and hydraulic control fully, with low cost.Air door control has switching flexibly with the gas control device, and is easy and simple to handle, and consumption gas is few, safeguards characteristic of simple.This apparatus structure is simple, volume is little, in light weight, install simply, easy to use, being installed in does not influence the space on the underworkings wall, uses promptly reliably safety again, in this area, has practicality widely.When pedestrian and mine car pass through air door, through the keying of operation gas control device realization air door, automatic blocking.This device is applicable to the place that gas and coal dust explosion hazard are arranged under the coal mine.
Description of drawings
Fig. 1 is a structural representation of the present invention.Fig. 2 is a principle schematic of the present invention.
Among the figure, 1 tunnel, 2 A doors, 3 B doors, 4 source of the gas casees, 5 Pneumatic controlled boxes, 6 Pneumatic controlled boxes, 7 source of the gas casees.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.
The gas control device is used in air door control of the present invention; Comprise the source of the gas case 4 that is arranged on A door 2 one sides and the control cabinet 5 of opposite side; And the control cabinet 7 of the source of the gas case 6 of B door 3 one sides and opposite side; Comprise that also cylinder and locking on the door body that is separately positioned on A door and B door detect the magnetic control valve, source of the gas case and control cabinet are equipped with door open button, door close button and emergency pressure relief hand valve; Air line is connected under source of the gas case primary air inlet and the mine, after source of the gas case filtration treatment, links to each other with control cabinet through secondary air feed tracheae; The door open button of source of the gas case, door close button and emergency pressure relief hand valve are connected with the corresponding part of control cabinet; Cylinder on the door body and locking detect the magnetic control valve and link to each other with control cabinet the corresponding interface, and the control cabinet of A door is controlled out with the control cabinet locking of B door, incoming interface is connected for crossing one another.There is air gauge source of the gas case top.
The gas control device is used in air door control of the present invention, is made up of source of the gas case and control cabinet two parts.Be applicable to coal mine lower wind door control, pedestrian and mine car through the time by the keying of this gas control device realization air door, automatic blocking.
Gas control device tunnel layout such as Fig. 1: in twice air door (A door and B door) both sides source of the gas case and control cabinet are installed, the casing front all is furnished with green door open button and red door close button.There are pressure meter, real-time display system pressure in source of the gas case top.
Gas control apparatus system principle such as Fig. 2: air line is connected under source of the gas case primary air inlet and the mine, after source of the gas case filtration treatment, links to each other with the secondary air feed tracheae of control cabinet through secondary air feed tracheae.2 buttons of source of the gas case and emergency pressure relief hand valve interface are connected with the control cabinet corresponding interface.Door body upper cylinder and locking detect the magnetic control valve and link to each other with control cabinet the corresponding interface, and the control cabinet locking is controlled out, incoming interface is the connection that crosses one another.
The source of the gas case of A door and B door is provided with gas-filtering device, and the secondary air supply pipe of source of the gas case and control cabinet, locking detect magnetic control valve, emergency pressure relief hand valve, green door open button and red door close button and all be connected with cylinder, and the mechanical part of cylinder connects the switch door.
Operating principle:
1: normally pass through:
When the pedestrian arrives the A door; If when the B door is in closed condition at this moment (detecting the magnetic control valve through locking detects), press the green door open button of A door, its signal is output after control cabinet is handled; Directly control A door cylinder is opened air door A; Send block signal to B gate control case simultaneously, the B door is carried out forced blocking, the B door can not be opened again; The pedestrian closes air door A through the red door close button that A must press A door opposite side behind the door; Its signal is output after control cabinet is handled, and directly controls the A door cylinder and close air door A, after the A door is closed fully; The control cabinet block signal can break off voluntarily, and the B door just can be opened; During reverse passing through, operating procedure is identical.
2: urgent reaching passed through unusually
When emergency need to take place the emergency unchaining locking to open the door; Or air door and gas control device generation abnormal conditions are can't normal door the time; Can draw back emergency pressure relief valve on A door source of the gas case or the control cabinet; Can manually draw back air door A, draw back emergency pressure relief valve on B door source of the gas case or the control cabinet, can manually draw back air door B.As to recover the gas control device, and needing the source of the gas case of this road air door and the emergency pressure relief hand valve on the Pneumatic controlled box all pushed back and reset, the gas control device will return to the normal operating condition before the emergency decompression automatically, and blocking function will recover automatically.
