Description
Technical field
The utility model belongs to mine ventilation technology field, particularly relates to a kind of Full pneumatic air door switch device.
Background technology
The safety in colliery seems particularly important concerning colliery, wherein, mine ventilation system as the key factor of relation mine safety, and air door in mine ventilation system whether can keep playing a part in mine ventilation system stable operation very important.At present, existing self-acting door all relies on electronic component to control, as relied on infrared rays as sensing element, utilizing electron master control case to carry out the self closing door controlled, but there is infrared ray automatic induction apparatus and circuit Main Control Tank cost is higher, and electric device should not be arranged in return airway, its scope of application is restricted.
Summary of the invention
The utility model aims to provide a kind of Full pneumatic air door switch device, solves electric device of the prior art and should not be arranged on restriction in return airway and the high problem of cost, be conducive to large-scale promotion.
The utility model discloses a kind of Full pneumatic air door switch device, comprise: two vehicle induction installations, form by linking below two-position three way mechanical valve and lance respectively, described lance is provided with three operating positions, is respectively an erectility, two states tilted to both sides; Flap valve, the air inlet port of described flap valve is connected with described two-position three way mechanical valve; Two-position three-way, gas control import and the flap valve outlet being connected two-position three way mechanical valve of described two-position three-way, the air inlet port of described two-position three-way is given a dinner for a visitor from afar source; Cylinder, described cylinder is provided with and extends and shorten two air inlet ports, is communicated with respectively with two gas outlets of two-position three-way, shortens between air inlet port and described two-position three-way gas outlet install pneumatic delayer at described cylinder; Air door, under described lance is embedded in the base plate of described air door both sides, one end of the piston rod of described cylinder is connected with air door by the rope be arranged on fixed pulley.
In order to prevent when one air door is opened, another road air door enforced opening when receiving start signal causes throttle locking device to damage, at source of the giving a dinner for a visitor from afar place of described Full pneumatic air door switch device, two-position three-way is installed, the blocking device of Full pneumatic air door switch device is overlapped in the connection second of described two-position three-way, for realizing when another road air door is opened, cut off the power source of this air door cylinder, described blocking device can be wind blocking device, also can be electric locking device, for playing the effect of locking opposite side air door, usually, when selecting electric locking device to make block sytem, need to add electromagnetic valve between described electric locking device and described two-position three-way, electromagnetic valve being converted electrical signals to wind number can realize.
In order to farthest reduce the noise in mine, the two-position three way mechanical valve be connected with lance adding noise reduction valve, also can add noise reduction valve on the two-position three-way at source place of giving a dinner for a visitor from afar.
The operating principle of this Full pneumatic air door switch device is: when vehicle passes through the lance position of any side, air door both sides, lance inclination, gas circuit conducting, cylinder elongation, air door are opened, vehicle is by after lance, although cylinder shortens gas circuit conducting, but due to the effect of pneumatic delayer, signal is adjustable at 30s() after really could reach cylinder and shorten air inlet port, when vehicle is completely by after air door (by opposite side lance), air door is adjustable after 30s() after just can automatically close.
