1. there is a fire-protection equipment for automatic open function, it is characterized in that, comprise:

  • One pneumatic valve member, connect a piston apparatus and a gas supply valve group, described gas supply valve group exports gas carrys out control piston device push rod start through described pneumatic valve member to described piston apparatus, and described piston apparatus connects window, and can control window unlatching;

    Described pneumatic valve member also comprises;

    One valve member main body, forms one first air-flow port, one second air-flow port, one the 3rd air-flow port and one the 4th air-flow port in side;

    In addition, valve member main body also forms a fixing column and passes through hole;

    One temperature sensing module, is arranged at the side of valve member main body, and more comprises;

    One fixing frame, is arranged at the side of valve member main body;

    One temperature sensing component, is arranged in fixing frame;

    Temperature sensing component can break because ambient temperature changes;

    AndOne fixing column, one end is against temperature sensing component, and one end passes through fixing frame and fixing column passes through hole;

    One movable valve plug, is placed in described valve member main body, forms a limited impression, one first depression and one second depression, then form containing space in inside in side, and wherein, the corresponding described fixing column of described limited impression passes through hole;

    In addition, movable valve plug also comprises an elastic component, and described elastic component is arranged at containing space, and leans valve member main body and movable valve plug respectively;

    When fixing column pass through fixing column pass through hole and against limited impression time, elastic component is squeezed and stores potential energy, now, the described first corresponding first air-flow port of depression and the second air-flow port, and the corresponding 3rd air-flow port of the second depression and the 4th air-flow port;

    Two sides of described first depression are respectively equiped with one first seal ring and one second seal ring, make the gas being placed in the first depression, only can flow through the first air-flow port and the second air-flow port;

    Two sides of described second depression are respectively equiped with one the 3rd seal ring and one the 4th seal ring, make the gas being placed in the second depression, only can flow through the 3rd air-flow port and the 4th air-flow port;

    Wherein, gas supply valve group exports gas, sequentially through the first air-flow port, first depression and the second air-flow port to piston apparatus, simultaneously, piston apparatus Exhaust Gas, sequentially through the 3rd air-flow port, second depression and the 4th air-flow port to gas supply valve group, the push rod of piston apparatus is outwards pushed, and window is unlocked;

    In addition, gas supply valve group exports gas, sequentially through the 4th air-flow port, second depression and the 3rd air-flow port to piston apparatus, simultaneously, piston apparatus Exhaust Gas, sequentially through the second air-flow port, first depression and the first air-flow port to gas supply valve group, the push rod of piston apparatus is inwardly promoted, and window is closed;

    When fixing column leaves limited impression, elastic component release potential energy, promote movable valve plug displacement, gas then can flow to the second air-flow port from containing space, and the push rod of piston apparatus is outwards pushed, and window is unlocked;

    One fixed cover, is arranged at one end of valve member main body;

    AndOne lancet unit, is arranged at one end of movable valve plug, and passes through described fixed cover;

    Lancet unit is hollow aspect, and gas can pass through the center of lancet unit to containing space;

    AndOne gas cylinder, is installed in fixed cover, includes pressurized gas, and forms diaphragm seal at the bottleneck of gas cylinder;

    When fixing column is against limited impression, the position of movable valve plug restriction lancet unit, the diaphragm seal of lancet unit and gas cylinder is kept at a distance, and now, elastic component is squeezed and stores potential energy;

    When temperature sensing component breaks, fixing column leaves limited impression, and elastic component release potential energy also promotes the diaphragm seal that movable valve plug and lancet unit pierce through gas cylinder;

    After the diaphragm seal of gas cylinder is pierced, pressurized gas passes through lancet unit to containing space, then through the second air-flow port to piston apparatus, the push rod of piston apparatus is outwards pushed, and push rod then drives window, and window is opened automatically.
